PREFACE

The following treatise on Sextus Empiricus and Greek Scepticism

has been prepared to supply a need much felt in the English

language by students of Greek philosophy. For while other

schools of Greek philosophy have been exhaustively and

critically discussed by English scholars, there are few sources

of information available to the student who wishes to make

himself familiar with the teachings of Pyrrhonism. The aim has

been, accordingly, to give a concise presentation of Pyrrhonism

in relation to its historical development and the Scepticism of

the Academy, with critical references to the French and German

works existing on the subject. The time and manner of the

connection of Sextus Empiricus with the Pyrrhonean School has

also been discussed.

As the First Book of the _Hypotyposes_, or Pyrrhonic Sketches by

Sextus Empiricus, contains the substance of the teachings of

Pyrrhonism, it has been hoped that a translation of it into

English might prove a useful contribution to the literature on

Pyrrhonism, and this translation has been added to the critical

part of the work.

In making this translation, and in the general study of the

works of Sextus, the Greek text of Immanuel Bekker, Berlin,

1842, has been used, with frequent consultation of the text of

J.A. Fabricius, 1718, which was taken directly from the existing

manuscripts of the works of Sextus. The divisions into chapters,

with the headings of the chapters in the translation, is the

same as Fabricius gives from the manuscripts, although not used

by Bekker, and the numbers of the paragraphs are the same as

those given by both Fabricius and Bekker. References to Diogenes

Laertius and other ancient works have been carefully verified.

The principal modern authors consulted are the following:

Ritter, _Geschichte der Philosophie_, II. Auf., Hamburg,

1836-38.

1879-89.

CHAPTER I.

_The Historical Relations of Sextus Empiricus._

Interest has revived in the works of Sextus Empiricus in recent

times, especially, one may say, since the date of Herbart. There

is much in the writings of Sextus that finds a parallel in the

methods of modern philosophy. There is a common starting-point

in the study of the power and limitations of human thought.

There is a common desire to investigate the phenomena of

sense-perception, and the genetic relations of man to the lower

animals, and a common interest in the theory of human knowledge.

While, however, some of the pages of Sextus' works would form a

possible introduction to certain lines of modern philosophical

thought, we cannot carry the analogy farther, for Pyrrhonism as

a whole lacked the essential element of all philosophical

progress, which is a belief in the possibility of finding and

establishing the truth in the subjects investigated.

Before beginning a critical study of the writings of Sextus

Empiricus, and the light which they throw on the development of

Greek Scepticism, it is necessary to make ourselves somewhat

familiar with the environment in which he lived and wrote. We

shall thus be able to comprehend more fully the standpoint from

which he regarded philosophical questions.

Let us accordingly attempt to give some details of his life,

including his profession, the time when he lived, the place of

his birth, the country in which he taught, and the general aim

and character of his works. Here, however, we encounter great

difficulties, for although we possess most of the writings of

Sextus well preserved, the evidence which they provide on the

points mentioned is very slight. He does not give us

biographical details in regard to himself, nor does he refer to

his contemporaries in a way to afford any exact knowledge of

them. His name even furnishes us with a problem impossible of

solution. He is called [Greek: Sextos ho empeirikos] by Diogenes

Laertius[1]: [Greek: Hêrodotou de diêkouse Sextos ho empeirikos

hou kai ta deka tôn skeptikôn kai alla kallista' Sextou de

diêkouse Satorninos ho Kythênas, empeirikos kai autos]. Although

in this passage Diogenes speaks of Sextus the second time

without the surname, we cannot understand the meaning otherwise

than that Diogenes considered Sextus a physician of the

Empirical School. Other evidence also is not wanting that Sextus

bore this surname. Fabricius, in his edition of the works of

Sextus, quotes from the _Tabella de Sectis Medicorum_ of

Lambecius the statement that Sextus was called Empiricus because

of his position in medicine.[2]

Pseudo-Galen also refers to him as one of the directors of the

Empirical School, and calls him [Greek: Sextos ho

empeirikos].[3] His name is often found in the manuscripts

written with the surname, as for example at the end of _Logic

II_.[4] In other places it is found written without the surname,

as Fabricius testifies, where Sextus is mentioned as a Sceptic

in connection with Pyrrho.

[2] Fabricius _Testimonia_, p. 2.

[3] Pseudo-Galen _Isag._ 4; Fabricius _Testimonia_, p. 2.

[4] Bekker _Math._ VIII. 481.

The Sceptical School was long closely connected with the

Empirical School of medicine, and the later Pyrrhoneans, when

they were physicians, as was often the case, belonged for the

most part to this school. Menedotus of Nicomedia is the first

Sceptic, however, who is formally spoken of as an Empirical

physician,[1] and his contemporary Theodas of Laodicea was also

an Empirical physician. The date of Menedotus and Theodas is

difficult to fix, but Brochard and Hass agree that it was about

150 A.D.[2] After the time of these two physicians, who were

also each in turn at the head of the Sceptical School,[3] there

seems to have been a definite alliance between Pyrrhonism and

Empiricism in medicine, and we have every reason to believe that

this alliance existed until the time of Sextus.

[2] Brochard _Op. cit. Livre_ IV. p. 311.

[3] Diog. IX. 12, 116.

The difficulty in regard to the name arises from Sextus' own

testimony. In the first book of the _Hypotyposes_ he takes

strong ground against the identity of Pyrrhonism and Empiricism

in medicine. Although he introduces his objections with the

admission that "some say that they are the same," in recognition

of the close union that had existed between them, he goes on to

say that "Empiricism is neither Scepticism itself, nor would it

suit the Sceptic to take that sect upon himself",[1] for the

reason that Empiricism maintains dogmatically the impossibility

of knowledge, but he would prefer to belong to the Methodical

School, which was the only medical school worthy of the Sceptic.

"For this alone of all the medical sects, does not proceed

rashly it seems to me, in regard to unknown things, and does not

presume to say whether they are comprehensible or not, but it is

guided by phenomena.[2] It will thus be seen that the Methodical

School of medicine has a certain relationship to Scepticism

which is closer than that of the other medical sects."[3]

[2] _Hyp_. I. 237.

[3] _Hyp_. I. 241.

We know from the testimony of Sextus himself that he was a

physician. In one case he uses the first person for himself as a

physician,[1] and in another he speaks of Asclepius as "the

founder of our science,"[2] and all his illustrations show a

breadth and variety of medical knowledge that only a physician

could possess. He published a medical work which he refers to

once as [Greek: iatrika hupomnêmata],[3] and again as [Greek:

empeirika hupomnêmata][4] These passages probably refer to the

same work,[5] which, unfortunately for the solution of the

difficult question that we have in hand, is lost, and nothing is

known of its contents.

In apparent contradiction to his statement in _Hypotyposes_ I.,

that Scepticism and Empiricism are opposed to each other, in

that Empiricism denies the possibility of knowledge, and

Scepticism makes no dogmatic statements of any kind, Sextus

classes the Sceptics and Empiricists together in another

instance, as regarding knowledge as impossible[6] [Greek: all oi

men phasin auta mê katalambanesthai, hôster hoi apo tês

empeirias iatroi kai hoi apo tês skepseôs phiolosophoi]. In

another case, on the contrary, he contrasts the Sceptics sharply

with the Empiricists in regard to the [Greek: apodeixeis].[7]

[Greek: hoi de empeirikoi anairousin, hoi de skeptikoi en epochê

tautên ephylaxan].

Pappenheim thinks that Sextus belonged to the Methodical School,

both from his strong expression in favor of that school in

_Hyp_. I. 236, as above, and also because many of his

medical opinions, as found in his works, agree with the

teachings of the Methodical School, more nearly than with those

of the Empiricists. Pappenheim also claims that we find no

inconsistency with this view in the passage given where Sextus

classes the Sceptics with the Empiricists, but considers that

statement an instance of carelessness in expressing himself, on

the part of Sextus.[1]

[1] _Lebensverhältnisse des Sex. Em._ 36.

The position of Pappenheim is assailable for the reason that in

dealing with any problem regarding an author on the basis of

internal evidence, we have no right to consider one of his

statements worthy of weight, and another one unworthy, on the

supposition that he expressed himself carelessly in the second

instance. Rather must we attempt to find his true standpoint by

fairly meeting all the difficulties offered in apparently

conflicting passages. This has been attempted by Zeller,

Brochard, Natorp and others, with the general result that all

things considered they think without doubt that Sextus belonged

to the Empirical School.[1] His other references are too strong

to allow his fidelity to it to be doubted. He is called one of

the leaders of Empiricism by Pseudo-Galen, and his only medical

work bore the title [Greek: empeirika hupomnêmata.] The opinion

of the writers above referred to is that the passage which we

have quoted from the _Hypotyposes_ does not necessarily mean

that Sextus was not an Empiricist, but as he was more of a

Sceptic than a physician, he gave preference to those doctrines

that were most consistent with Scepticism, and accordingly

claimed that it was not absolutely necessary that a Sceptic

physician should be an Empiricist. Natorp considers that the

different standpoint from which Sextus judges the Empirical and

Methodical Schools in his different works is accounted for on

the supposition that he was an Empiricist, but disagreed with

that school on the one point only.[2] Natorp points out that

Sextus does not speak more favourably of the medical stand of

the Methodical School, but only compares the way in which both

schools regarded the question of the possibility of knowledge,

and thinks that Sextus could have been an Empiricist as a

physician notwithstanding his condemnation of the attitude of

the Empirical School in relation to the theory of knowledge.

This difference between the two schools was a small one, and on

a subtle and unimportant point; in fact, a difference in

philosophical theory, and not in medical practice.

III. 15; Natorp _Op. cit._ p. 155.

[2] Natorp _Op. cit_. 157.

While we would agree with the authors above referred to, that

Sextus very probably recognized the bond between the Empirical

School of medicine and Pyrrhonism, yet to make his possible

connection with that school the explanation of his name, gives

him more prominence as a physician than is consistent with what

we know of his career. The long continued union of Empiricism

and Scepticism would naturally support the view that Sextus was,

at least during the earlier part of his life, a physician of

that school, and yet it may be that he was not named Empiricus

for that reason. There is one instance in ancient writings where

Empiricus is known as a simple proper name.[1] It may have been

a proper name in Sextus' case, or there are many other ways in

which it could have originated, as those who have studied the

origin of names will readily grant, perhaps indeed, from the

title of the above-named work, [Greek: empeirika hupomnêmata.]

The chief argument for this view of the case is that there were

other leaders of the Sceptical School, for whom we can claim far

greater influence as Empiricists than for Sextus, and for whom

the surname Empiricus would have been more appropriate, if it

was given in consequence of prominence in the Empirical School.

Sextus is known to the world as a Sceptic, and not as a

physician. He was classed in later times with Pyrrho, and his

philosophical works survived, while his medical writings did

not, but are chiefly known from his own mention of them.

Moreover, the passage which we have quoted from the

_Hypotyposes_ is too strong to allow us easily to believe that

Sextus remained all his life a member of the Empirical School.

He could hardly have said, "Nor would it suit the Sceptic to

take that sect upon himself," if he at the same time belonged to

it. His other references to the Empirical School, of a more

favorable character, can be easily explained on the ground of

the long continued connection which had existed between the two

schools. It is quite possible to suppose that Sextus was an

Empiricist a part of his life, and afterwards found the

Methodical School more to his liking, and such a change would

not in any way have affected his stand as a physician.

[1] Pappenheim _Leb. Ver. Sex. Em_. 6.

In regard to the exact time when Sextus Empiricus lived, we gain

very little knowledge from internal evidence, and outside

sources of information are equally uncertain. Diogenes Laertius

must have been a generation younger than Sextus, as he mentions

the disciple of Sextus, Saturninus, as an Empirical

physician.[1] The time of Diogenes is usually estimated as the

first half of the third century A.D.,[2] therefore Sextus cannot

be brought forward later than the beginning of the century.

Sextus, however, directs his writings entirely against the

Dogmatics, by whom he distinctly states that he means the

Stoics,[3] and the influence of the Stoics began to decline in

the beginning of the third century A.D. A fact often used as a

help in fixing the date of Sextus is his mention of Basilides

the Stoic,[4] [Greek: alla kai oi stôikoi, ôs oi peri ton

Basileidên]. This Basilides was supposed to be identical with

one of the teachers of Marcus Aurelius.[5] This is accepted by

Zeller in the second edition of his _History of Philosophy_, but

not in the third for the reason that Sextus, in all the work

from which this reference is taken, _i.e. Math_. VII.-XI.,

mentions no one besides Aenesidemus, who lived later than the

middle of the last century B.C.[6] The Basilides referred to by

Sextus may be one mentioned in a list of twenty Stoics, in a

fragment of Diogenes Laertius, recently published in Berlin by

Val Rose.[7] Too much importance has, however, been given to the

relation of the mention of Basilides the Stoic to the question

of the date of Sextus. Even if the Basilides referred to by

Sextus is granted to have been the teacher of Marcus Aurelius,

it only serves to show that Sextus lived either at the same time

with Marcus Aurelius or after him, which is a conclusion that we

must in any case reach for other reasons.

The fact that has caused the greatest uncertainty in regard to

the date of Sextus is that Claudius Galen in his works mentions

several Sceptics who were also physicians of the Empirical

School,[1] and often speaks of Herodotus, supposed to be

identical with the teacher of Sextus given by Diogenes

Laertius,[2] but makes no reference whatever to Sextus. As

Galen's time passes the limit of the second century A.D., we

must either infer that Sextus was not the well-known physician

that he was stated to be by Pseudo-Galen, and consequently not

known to Galen, or that Galen wrote before Sextus became

prominent as a Sceptic. This silence on the part of Galen in

regard to Sextus increases the doubt, caused by Sextus' own

criticism of the Empirical School of medicine, as to his having

been an Empiricist. The question is made more complicated, as it

is difficult to fix the identity of the Herodotus so often

referred to by Galen.[3] As Galen died about 200 A.D. at the age

of seventy,[4] we should fix the date of Sextus early in the

third century, and that of Diogenes perhaps a little later than

the middle, were it not that early in the third century the

Stoics began to decline in influence, and could hardly have

excited the warmth of animosity displayed by Sextus. We must

then suppose that Sextus wrote at the very latter part of the

second century, and either that Galen did not know him, or that

Galen's books were published before Sextus became prominent

either as a physician or as a Sceptic. The fact that he may have

been better known as the latter than as the former does not

sufficiently account for Galen's silence, as other Sceptics are

mentioned by him of less importance than Sextus, and the latter,

even if not as great a physician as Pseudo-Galen asserts, was

certainly both a Sceptic and a physician, and must have belonged

to one of the two medical schools so thoroughly discussed by

Galen--either the Empirical or the Methodical. Therefore, if

Sextus were a contemporary of Galen, he was so far removed from

the circle of Galen's acquaintances as to have made no

impression upon him, either as a Sceptic or a physician, a

supposition that is very improbable. We must then fix the date

of Sextus late in the second century, and conclude that the

climax of his public career was reached after Galen had finished

those of his writings which are still extant.

Sextus has a Latin name, but he was a Greek; we know this from

his own statement.[1] We also know that he must have been a

Greek from the beauty and facility of his style, and from his

acquaintance with Greek dialects. The place of his birth can

only, however, be conjectured, from arguments indirectly derived

from his writings. His constant references throughout his works

to the minute customs of different nations ought to give us a

clue to the solution of this question, but strange to say they

do not give us a decided one. Of these references a large

number, however, relate to the customs of Libya, showing a

minute knowledge in regard to the political and religious

customs of this land that he displays in regard to no other

country except Egypt.[2] Fabricius thinks Libya was not his

birth place because of a reference which he makes to it in the

_Hypotyposes_--[Greek: Thrakôn de kai Gaitoulôn (Libyôn de

ethnos touto)].[3] This conclusion is, however, entirely

unfounded, as the explanation of Sextus simply shows that the

people whom he was then addressing were not familiar with the

nations of Libya. Suidas speaks of two men called Sextus, one

from Chæronea and one from Libya, both of whom he calls

Sceptics, and to one of whom he attributes Sextus' books. All

authorities agree in asserting that great confusion exists in

the works of Suidas; and Fabricius, Zeller, and Pappenheim place

no weight upon this testimony of Suidas.[4] Haas, however,

contends[5] that it is unreasonable to suppose that this

confusion could go as far as to attribute the writings of Sextus

Empiricus to Sextus of Chæronea, and also make the latter a

Sceptic, and he considers it far more reasonable to accept the

testimony of Suidas, as it coincides so well with the internal

evidence of Sextus' writings in regard to his native land. It is

nevertheless evident, from his familiarity with the customs,

language, and laws of Athens, Alexandria and Rome, that he must

have resided at some time in each of these cities.

Of all the problems connected with the historical details of the

life of Sextus, the one that is the most difficult of solution,

and also the most important for our present purpose of making a

critical study of his teaching, is to fix the seat of the

Sceptical School during the time that he was in charge of it.

The _Hypotyposes_ are lectures delivered in public in that

period of his life. Where then were they delivered? We know that

the Sceptical School must have had a long continued existence as

a definite philosophical movement, although some have contended

otherwise. The fact of its existence as an organized direction

of thought, is demonstrated by its formulated teachings, and the

list given by Diogenes Laertius of its principal leaders,[1] and

by references from the writings of Sextus. In the first book of

_Hypotyposes_ he refers to Scepticism as a distinct system of

philosophy, [Greek: kai taen diakrisin taes skepseos apo ton

parakeimenon autae philosophion].[2] He speaks also of the older

Sceptics,[3] and the later Sceptics.[4]

Pyrrho, the founder of the school, taught in Elis, his native

village; but even as early as the time of Timon, his immediate

follower, his teachings were somewhat known in Alexandria, where

Timon for a while resided.[5] The immediate disciples of Timon,

as given by Diogenes, were not men known in Greece or mentioned

in Greek writings. Then we have the well-known testimony of

Aristocles the Peripatetic in regard to Aenesidemus, that he

taught Pyrrhonism in Alexandria[6]--[Greek: echthes kai proaen

en Alexandreia tae kat' Aigypton Ainaesidaemos tis anazopyrein

aerxato ton huthlon touton].

[4] _Hyp_. I. 164.

[5] Chaignet _Op. cit._ 45.

[6] Aristocles of Euseb. _Praep. Ev._ XIV. E. 446.

This was after the dogmatic tendency of the Academy under

Antiochus and his followers had driven Pyrrhonism from the

partial union with the Academy, which it had experienced after

the breaking up of the school under the immediate successors of

Timon. Aenesidemus taught about the time of our era in

Alexandria, and established the school there anew; and his

followers are spoken of in a way that presupposes their

continuing in the same place. There is every reason to think

that the connection of Sextus with Alexandria was an intimate

one, not only because Alexandria had been for so long a time the

seat of Pyrrhonism, but also from internal evidence from his

writings and their subsequent historical influence; and yet the

_Hypotyposes_ could not have been delivered in Alexandria, as he

often refers to that place in comparison with the place where he

was then speaking. He says, furthermore, that he teaches in the

same place where his master taught.[1] [Greek: Blepon te hoti

entha ho huphaegaetaes ho emos dielegeto, entautha ego nun

dialegomai]. Therefore the school must have been removed from

Alexandria, in or before the time of the teacher of Sextus, to

some other centre. The _Hypotyposes_ are from beginning to end a

direct attack on the Dogmatics; therefore Sextus must have

taught either in some city where the dogmatic philosophy was

strong, or in some rival philosophical centre. The _Hypotyposes_

show also that the writer had access to some large library.

Alexandria, Rome and Athens are the three places the most

probable for selection for such a purpose. For whatever reason

the seat of the school was removed from Alexandria by the master

of Sextus, or by himself, from the place where it had so long

been united with the Empirical School of medicine, Athens would

seem the most suitable city for its recontinuance, in the land

where Pyrrhonism first had its birth. Sextus, however, in one

instance, in referring to things invisible because of their

outward relations, says in illustration, "as the city of Athens

is invisible to us at present."[2] In other places also he

contrasts the Athenians with the people whom he is addressing,

equally with the Alexandrians, thus putting Athens as well as

Alexandria out of the question.

[2] _Hyp._ II. 98.

Of the different writers on Sextus Empiricus, those who have

treated this part of the subject most critically are Haas and

Pappenheim. We will therefore consider, somewhat at length, the

results presented by these two authors. Haas thinks that the

_Hypotyposes_ were delivered in Rome for the following reasons.

Sextus' lectures must have been given in some centre of

philosophical schools and of learning. He never opposes Roman

relations to those of the place where he is speaking, as he does

in regard to Athens and Alexandria. He uses the name "Romans"

only three times,[1] once comparing them to the Rhodians, once

to the Persians, and once in general to other nations.[2] In the

first two of these references, the expression "among the Romans"

in the first part of the antithesis is followed by the

expression, "among us," in the second part, which Haas

understands to be synonymous. The third reference is in regard

to a Roman law, and the use of the word 'Roman' does not at all

show that Sextus was not then in Rome. The character of the laws

referred to by Sextus as [Greek: par' haemin] shows that they

were always Roman laws, and his definition of law[3] is

especially a definition of Roman law. This argument might, it

would seem, apply to any part of the Roman Empire, but Haas

claims that the whole relation of law to custom as treated of by

Sextus, and all his statements of customs forbidden at that time

by law, point to Rome as the place of his residence. Further,

Haas considers the Herodotus mentioned by Galen[4] as a

prominent physician in Rome, to have been the predecessor and

master of Sextus, in whose place Sextus says that he is

teaching.[5] Haas also thinks that Sextus' refutation of the

identity of Pyrrhonism with Empiricism evidently refers to a

paragraph in Galen's _Subfiguratio Empirica_,[6] which would be

natural if the _Hypotyposes_ were written shortly after Galen's

_Sub. Em._, and in the same place. Further, Hippolytus, who

wrote in or near Rome very soon after the time of Sextus,

apparently used the _Hypotyposes_, which would be more natural

if he wrote in the same place. According to Haas, every thing in

internal evidence, and outward testimony, points to Rome as

having been the city where Sextus occupied his position as the

head of the Sceptical School.

Coming now to the position of Pappenheim on this subject, we

find that he takes very decided ground against the seat of the

Sceptical School having been in Rome, even for a short time, in

his latest publication regarding it.[1] This opinion is the

result of late study on the part of Pappenheim, for in his work

on the _Lebensverhältnisse des Sextus Empiricus_ Berlin 1875, he

says, "Dass Herodotus in Rom lebte sagt Galen. Vermuthlich auch

Sextus." His reasons given in the later article for not

connecting the Sceptical School at all with Rome are as follows.

He finds no proof of the influence of Scepticism in Rome, as

Cicero remarks that Pyrrhonism is extinct,[2] and he also gives

weight to the well-known sarcastic saying of Seneca, _Quis est

qui tradat praecepta Pyrrhonis!_[3] While Haas claims that

Sextus would naturally seek one of the centres of dogmatism, in

order most effectively to combat it, Pappenheim, on the

contrary, contends that it would have been foolishness on the

part of Sextus to think of starting the Sceptical School in

Rome, where Stoicism was the favored philosophy of the Roman

Emperors; and when either for the possible reason of strife

between the Empirical and Methodical Schools, or for some other

cause, the Pyrrhonean School was removed from Alexandria,

Pappenheim claims that all testimony points to the conclusion

that it was founded in some city of the East. The name of Sextus

is never known in Roman literature, but in the East, on the

contrary, literature speaks for centuries of Sextus and Pyrrho.

The _Hypotyposes_, especially, were well-known in the East, and

references to Sextus are found there in philosophical and

religious dogmatic writings. The Emperor Julian makes use of the

works of Sextus, and he is frequently quoted by the Church

Fathers of the Eastern Church.[4] Pappenheim accordingly

concludes that the seat of Pyrrhonism after the school was

removed from Alexandria, was in some unknown city of the East.

Geschichte der Phil._ 1888.

[2] Cicero _De Orat._ III. 17, 62.

[3] Seneca _nat. qu._ VII. 32. 2.

[4] Fabricius _de Sexto Empirico Testimonia_.

In estimating the weight of these arguments, we must accept with

Pappenheim the close connection of Pyrrhonism with Alexandria,

and the subsequent influence which it exerted upon the

literature of the East. All historical relations tend to fix the

permanent seat of Pyrrhonism, after its separation from the

Academy, in Alexandria. There is nothing to point to its removal

from Alexandria before the time of Menodotus, who is the teacher

of Herodotus,[1] and for many reasons to be considered the real

teacher of Sextus. It was Menodotus who perfected the Empirical

doctrines, and who brought about an official union between

Scepticism and Empiricism, and who gave Pyrrhonism in great

measure, the _éclat_ that it enjoyed in Alexandria, and who

appears to have been the most powerful influence in the school,

from the time of Aenesidemus to that of Sextus. Furthermore,

Sextus' familiarity with Alexandrian customs bears the imprint

of original knowledge, and he cannot, as Zeller implies, be

accepted as simply quoting. One could hardly agree with

Zeller,[2] that the familiarity shown by Sextus with the customs

of both Alexandria and Rome in the _Hypotyposes_ does not

necessarily show that he ever lived in either of those places,

because a large part of his works are compilations from other

books; but on the contrary, the careful reader of Sextus' works

must find in all of them much evidence of personal knowledge of

Alexandria, Athens and Rome.

[1] Diog. IX. 12, 116.

[2] Zeller _Op. cit._ III. p. 39.

A part of Sextus' books also may have been written in

Alexandria. [Greek: Pros phusikous] could have been written in

Alexandria.[1] If these were also lectures, then Sextus taught

in Alexandria as well as elsewhere. The history of Eastern

literature for the centuries immediately following the time of

Sextus, showing as it does in so many instances the influence of

Pyrrhonism, and a knowledge of the _Hypotyposes_, furnishes us

with an incontestable proof that the school could not have been

for a long time removed from the East, and the absence of such

knowledge in Roman literature is also a strong argument against

its long continuance in that city. It would seem, however, from

all the data at command, that during the years that the

Sceptical School was removed from Alexandria, its head quarters

were in Rome, and that the Pyrrhonean _Hypotyposes_ were

delivered in Rome. Let us briefly consider the arguments in

favour of such a hypothesis. Scepticism was not unknown in Rome.

Pappenheim quotes the remark of Cicero that Pyrrhonism was long

since dead, and the sarcasm of Seneca, _Quis est qui tradat

praecepta Pyrrhonis?_ as an argument against the knowledge of

Pyrrhonism in Rome. We must remember, however, that in Cicero's

time Aenesidemus had not yet separated himself from the Academy;

or if we consider the Lucius Tubero to whom Aenesidemus

dedicated his works, as the same Lucius Tubero who was the

friend of Cicero in his youth, and accordingly fix the date of

Aenesidemus about 50 B.C.,[2] even then Aenesidemus' work in

Alexandria was too late to have necessarily been known to

Cicero, whose remark must have been referred to the old school

of Scepticism. Should we grant, however, that the statements of

Cicero and Seneca prove that in their time Pyrrhonism was

extinct in Rome, they certainly do not show that after their

death it could not have again revived, for the _Hypotyposes_

were delivered more than a century after the death of Seneca.

There are very few writers in Aenesidemus' own time who showed

any influence of his teachings.[3] This influence was felt

later, as Pyrrhonism became better known. That Pyrrhonism

received some attention in Rome before the time of Sextus is

nevertheless demonstrated by the teachings of Favorinus there.

Although Favorinus was known as an Academician, the title of his

principal work was [Greek: tous philosophoumenous autô tôn

logôn, hôn aristoi hoi Purrhôneioi].[4] Suidas calls Favorinus a

great author and learned in all science and philosophy,[5] and

Favorinus made Rome the centre of his teaching and writing. His

date is fixed by Zeller at 80-150 A.D., therefore Pyrrhonism was

known in Rome shortly before the time of Sextus.

Geschichte der Phil._, 1888; _Adv. Math._ X. 15, 95.

[3] Zeller _Op. cit._ p. 63.

[4] Zeller _Op. cit._ p. 67.

[5] Brochard _Op. cit._ 329.

The whole tone of the _Hypotyposes_, with the constant

references to the Stoics as living present opponents, shows that

these lectures must have been delivered in one of the centres of

Stoicism. As Alexandria and Athens are out of the question, all

testimony points to Rome as having been the seat of the

Pyrrhonean School, for at least a part of the time that Sextus

was at its head. We would then accept the teacher of Sextus, in

whose place he says he taught, as the Herodotus so often

referred to by Galen[1] who lived in Rome. Sextus' frequent

references to Asclepiades, whom he mentions ten different times

by name in his works,[2] speak in favour of Rome in the matter

under discussion, as Asclepiades made that city one of the

centres of medical culture. On the other hand, the fact that

there is no trace of the _Hypotyposes_ in later Roman

literature, with the one exception of the works of Hippolytus,

as opposed to the wide-spread knowledge of them shown in the

East for centuries, is incontestable historical proof that the

Sceptical School could not long have had its seat at Rome. From

the two passages given above from Sextus' work against physics,

he must either have written that book in Alexandria, it would

seem, or have quoted those passages from some other work. May we

not then conclude, that Sextus was at the head of the school in

Rome for a short time, where it may have been removed

temporarily, on account of the difficulty with the Empiricists,

implied in _Hyp_. I. 236-241, or in order to be better able to

attack the Stoics, but that he also taught in Alexandria, where

the real home of the school was certainly found? There it

probably came to an end about fifty years after the time of

Sextus, and from that centre the Sceptical works of Sextus had

their wide-spread influence in the East.

[1] Galen VIII. 751.

[2] Bekker _Index_.

The books of Sextus Empiricus furnish us with the best and

fullest presentation of ancient Scepticism which has been

preserved to modern times, and give Sextus the position of one

of the greatest men of the Sceptical School. His works which are

still extant are the _Pyrrhonean Hypotyposes_ in three volumes,

and the two works comprising eleven books which have been united

in later times under the title of [Greek: pros mathêmatikous],

one of which is directed against the sciences in general, and

the other against the dogmatic philosophers. The six books

composing the first of these are written respectively against

grammarians, rhetoricians, geometricians, arithmeticians,

astronomers and musicians. The five books of the latter consist

of two against the logicians, two against physics, and one

against systems of morals. If the last short work of the first

book directed against the arithmeticians is combined with the

one preceding against the geometricians, as it well could be,

the two works together would be divided into ten different

parts; there is evidence to show that in ancient times such a

division was made.[1] There were two other works of Sextus which

are now lost, the medical work before referred to, and a book

entitled [Greek: peri psuchês]. The character of the extant

works of Sextus is similar, as they are all directed either

against science or against the dogmatics, and they all present

the negative side of Pyrrhonism. The vast array of arguments

comprising the subject-matter, often repeated in the same and

different forms, are evidently taken largely from the Sceptical

works which Sextus had resource to, and are, in fact, a summing

up of all the wisdom of the Sceptical School. The style of these

books is fluent, and the Greek reminds one of Plutarch and

Thucydides, and although Sextus does not claim originality, but

presents in all cases the arguments of the Sceptic, yet the

illustrations and the form in which the arguments are presented,

often bear the marks of his own thought, and are characterized

here and there by a wealth of humor that has not been

sufficiently noticed in the critical works on Sextus. Of all the

authors who have reviewed Sextus, Brochard is the only one who

seems to have understood and appreciated his humorous side.

We shall now proceed to the consideration of the general

position and aim of Pyrrhonism.

CHAPTER II.

_The Position and Aim of Pyrrhonism_.

The first volume of the _Pyrrhonean Hypotyposes_ gives the most

complete statement found in any of the works of Sextus Empiricus

of the teachings of Pyrrhonism and its relation to other schools

of philosophy. The chief source of the subject-matter presented

is a work of the same name by Aenesidemus,[1] either directly

used by Sextus, or through the writings of those who followed

Aenesidemus. The comprehensive title [Greek: Purrhôneioi

hupotupôseis] was very probably used in general to designate

courses of lectures given by the leaders of the Sceptical

School.

In the opening chapters of the _Hypotyposes_ Sextus undertakes

to define the position and aim of Pyrrhonism.[2] In introducing

his subject he treats briefly of the differences between

philosophical schools, dividing them into three classes; those

which claim that they have found the truth, like the schools of

Aristotle and Epicurus and the Stoics; those which deny the

possibility of finding it, like that of the Academicians; and

those that still seek it, like the Sceptical School. The

accusation against the Academicians, that they denied the

possibility of finding the truth, was one that the Sceptics were

very fond of making. We shall discuss the justice of it later,

simply remarking here, that to affirm the "incomprehensibility

of the unknown," was a form of expression that the Pyrrhonists

themselves were sometimes betrayed into, notwithstanding their

careful avoidance of dogmatic statements.[3]

[1] Diog. IX. 11, 78.

[2] _Hyp._ I. 3, 4.

[3] _Adv. Math._ VIII. 191.

After defining the three kinds of philosophy as the Dogmatic,

the Academic and the Sceptic, Sextus reminds his hearers that he

does not speak dogmatically in anything that he says, but that

he intends simply to present the Sceptical arguments

historically, and as they appear to him. He characterizes his

treatment of the subject as general rather than critical,

including a statement of the character of Scepticism, its idea,

its principles, its manner of reasoning, its criterion and aim,

and a presentation of the Tropes, or aspects of doubt, and the

Sceptical formulae and the distinction between Scepticism and

the related schools of philosophy.[1]

The result of all the gradual changes which the development of

thought had brought about in the outward relations of the

Sceptical School, was to increase the earnestness of the claim

of the Sceptics to be simply followers of Pyrrho, the great

founder of the movement. In discussing the names given to the

Sceptics, Sextus gives precedence very decidedly to the title

"Pyrrhonean," because Pyrrho appears the best representative of

Scepticism, and more prominent than all who before him occupied

themselves with it.[2]

It was a question much discussed among philosophers in ancient

times, whether Pyrrhonism should be considered a philosophical

sect or not. Thus we find that Hippobotus in his work entitled

[Greek: peri haireseôn], written shortly before our era, does

not include Pyrrhonism among the other sects.[3] Diogenes

himself, after some hesitation remarking that many do not

consider it a sect, finally decides to call it so.[4]

[1] _Hyp._ I. 5, 6.

[2] _Hyp._ I. 7.

[3] Diog. _Pro._ 19.

[4] Diog. _Pro._ 20.

Sextus in discussing this subject calls Scepticism an [Greek:

agogê], or a movement, rather than a [Greek: hairesis], saying

that Scepticism is not a sect, if that word implies a systematic

arrangement of dogmas, for the Sceptic has no dogmas. If,

however, a sect may mean simply the following of a certain

system of reasoning according to what appears to be true, then

Scepticism is a sect.[1] From a quotation given later on by

Sextus from Aenesidemus, we know that the latter used the term

[Greek: agogê].[2] Sextus gives also the other titles, so well

known as having been applied to Scepticism, namely, [Greek:

zêtêtikê], [Greek: ephektikê], and [Greek: aporêtikê].[3] The

[Greek: dunamis][4] of Scepticism is to oppose the things of

sense and intellect in every possible way to each other, and

through the equal weight of things opposed, or [Greek:

isostheneia], to reach first the state of suspension of

judgement, and afterwards ataraxia, or "repose and tranquillity

of soul."[5] The purpose of Scepticism is then the hope of

ataraxia, and its origin was in the troubled state of mind

induced by the inequality of things, and uncertainty in regard

to the truth. Therefore, says Sextus, men of the greatest talent

began the Sceptical system by placing in opposition to every

argument an equal one, thus leading to a philosophical system

without a dogma, for the Sceptic claims that he has no dogma.[6]

The Sceptic is never supposed to state a decided opinion, but

only to say what appears to him. Even the Sceptical formulae,

such as "Nothing more,"[7] or "I decide nothing,"[8] or "All is

false," include themselves with other things. The only

statements that the Sceptic can make, are in regard to his own

sensations. He cannot deny that he is warm or cold or hungry.

Sextus replies to the charge that the Sceptics deny phenomena by

refuting it.[1] The Sceptic does not deny phenomena, because

they are the only criteria by which he can regulate his actions.

"We call the criterion of the Sceptical School the phenomenon,

meaning by this name the idea of it."[2] Phenomena are the only

things which the Sceptic does not deny, and he guides his life

by them. They are, however, subjective. Sextus distinctly

affirms that sensations are the phenomena,[3] and that they lie

in susceptibility and voluntary feeling, and that they

constitute the appearances of objects.[4] We see from this that

Sextus makes the only reality to consist in subjective

experience, but he does not follow this to its logical

conclusion, and doubt the existence of anything outside of mind.

He rather takes for granted that there is a something unknown

outside, about which the Sceptic can make no assertions.

Phenomena are the criteria according to which the Sceptic orders

his daily life, as he cannot be entirely inactive, and they

affect life in four different ways. They constitute the guidance

of nature, the impulse of feeling; they give rise to the

traditions of customs and laws, and make the teaching of the

arts important.[5] According to the tradition of laws and

customs, piety is a good in daily life, but it is not in itself

an abstract good. The Sceptic of Sextus' time also inculcated

the teaching of the arts, as indeed must be the case with

professing physicians, as most of the leading Sceptics were.

Sextus says, "We are not without energy in the arts which we

undertake."[6] This was a positive tendency which no philosophy,

however negative, could escape, and the Sceptic tried to avoid

inconsistency in this respect, by separating his philosophy from

his theory of life. His philosophy controlled his opinions, and

his life was governed by phenomena.

The aim of Pyrrhonism was ataraxia in those things which pertain

to opinion, and moderation in the things which life imposes.[1]

In other words, we find here the same natural desire of the

human being to rise above and beyond the limitations which pain

and passion impose, which is expressed in other forms, and under

other names, in other schools of philosophy. The method,

however, by which ataraxia or peace of mind could be reached,

was peculiar to the Sceptic. It is a state of psychological

equilibrium, which results from the equality of the weight of

different arguments that are opposed to each other, and the

consequent impossibility of affirming in regard to either one,

that it is correct.[2] The discovery of ataraxia was, in the

first instance, apparently accidental, for while the Sceptic

withheld his opinion, unable to decide what things were true,

and what things were false, ataraxia fortunately followed.[3]

After he had begun to philosophize, with a desire to

discriminate in regard to ideas, and to separate the true from

the false[4] during the time of [Greek: epochê], or suspension

of judgement, ataraxia followed as if by chance, as the shadow

follows the body.[5]

[5] _Hyp._ I. 29.

The Sceptic in seeking ataraxia in the things of opinion, does

not entirely escape from suffering from his sensations. He is

not wholly undisturbed, for he is sometimes cold and hungry, and

so on.[1] He claims, nevertheless, that he suffers less than the

dogmatist, who is beset with two kinds of suffering, one from

the feelings themselves, and also from the conviction that they

are by nature an evil.[2] To the Sceptic nothing is in itself

either an evil or a good, and so he thinks that "he escapes from

difficulties easier."[3] For instance, he who considers riches a

good in themselves, is unhappy in the loss of them, and in

possession of them is in fear of losing them, while the Sceptic,

remembering the Sceptical saying "No more," is untroubled in

whatever condition he may be found, as the loss of riches is no

more an evil than the possession of them is a good.[4] For he

who considers anything good or bad by nature is always troubled,

and when that which seemed good is not present with him, he

thinks that he is tortured by that which is by nature bad, and

follows after what he thinks to be good. Having acquired it,

however, he is not at rest, for his reason tells him that a

sudden change may deprive him of this thing that he considers a

good.[5] The Sceptic, however, endeavours neither to avoid nor

seek anything eagerly.[6]

Ataraxia came to the Sceptic as success in painting the foam on

a horse's mouth came to Apelles the painter. After many attempts

to do this, and many failures, he gave up in despair, and threw

the sponge at the picture that he had used to wipe the colors

from the painting with. As soon as it touched the picture it

produced a representation of the foam.[1] Thus the Sceptics were

never able to attain to ataraxia by examining the anomaly

between the phenomena and the things of thought, but it came to

them of its own accord just when they despaired of finding it.

The intellectual preparation for producing ataraxia, consists in

placing arguments in opposition to each other, both in regard to

phenomena, and to things of the intellect. By placing the

phenomenal in opposition to the phenomenal, the intellectual to

the intellectual, and the phenomenal to the intellectual, and

_vice versa_, the present to the present, past, and future, one

will find that no argument exists that is incontrovertible. It

is not necessary to accept any statement whatever as true, and

consequently a state of [Greek: epochê] may always be

maintained.[2] Although ataraxia concerns things of the opinion,

and must be preceded by the intellectual process described

above, it is not itself a function of the intellect, or any

subtle kind of reasoning, but seems to be rather a unique form

of moral perfection, leading to happiness, or is itself

happiness.

[1] _Hyp._ I. 28, 29.

[2] _Hyp._ I. 32-35.

It was the aim of Scepticism to know nothing, and to assert

nothing in regard to any subject, but at the same time not to

affirm that knowledge on all subjects is impossible, and

consequently to have the attitude of still seeking. The

standpoint of Pyrrhonism was materialistic. We find from the

teachings of Sextus that he affirmed the non-existence of the

soul,[1] or the ego, and denied absolute existence

altogether.[2] The introductory statements of Diogenes regarding

Pyrrhonism would agree with this standpoint.[3]

There is no criterion of truth in Scepticism. We cannot prove

that the phenomena represent objects, or find out what the

relation of phenomena to objects is. There is no criterion to

tell us which one is true of all the different representations

of the same object, and of all the varieties of sensation that

arise through the many phases of relativity of the conditions

which control the character of the phenomena.

Every effort to find the truth can deal only with phenomena, and

absolute reality can never be known.

CHAPTER III.

_The Sceptical Tropes_.

The exposition of the Tropes of Pyrrhonism constitutes

historically and philosophically the most important part of the

writings of Sextus Empiricus. These Tropes represent the sum

total of the wisdom of the older Sceptical School, and were held

in high respect for centuries, not only by the Pyrrhoneans, but

also by many outside the narrow limits of that School. In the

first book of the _Hypotyposes_ Sextus gives two classes of

Tropes, those of [Greek: epochê] and the eight Tropes of

Aenesidemus against Aetiology.

The Tropes of [Greek: epochê] are arranged in groups of ten,

five and two, according to the period of the Sceptical School to

which they belong; the first of these groups is historically the

most important, or the Ten Tropes of [Greek: epochê], as these

are far more closely connected with the general development of

Scepticism, than the later ones. By the name [Greek: tropos] or

Trope, the Sceptic understood a manner of thought, or form of

argument, or standpoint of judgement. It was a term common in

Greek philosophy, used in this sense, from the time of

Aristotle.[1] The Stoics, however, used the word with a

different meaning from that attributed to it by the Sceptics.[2]

Stephanus and Fabricius translate it by the Latin word

_modus_[3] and [Greek: tropos] also is often used

interchangeably with the word [Greek: logos] by Sextus, Diogenes

Laertius, and others; sometimes also as synonymous with [Greek:

topos],[4] and [Greek: typos] is found in the oldest edition of

Sextus.[5] Diogenes defines the word as the standpoint, or

manner of argument, by which the Sceptics arrived at the

condition of doubt, in consequence of the equality of

probabilities, and he calls the Tropes, the ten Tropes of

doubt.[6] All writers on Pyrrhonism after the time of

Aenesidemus give the Tropes the principal place in their

treatment of the subject. Sextus occupies two thirds of the

first book of the _Hypotyposes_ in stating and discussing them;

and about one fourth of his presentation of Scepticism is

devoted to the Tropes by Diogenes. In addition to these two

authors, Aristocles the Peripatetic refers to them in his attack

on Scepticism.[7] Favorinus wrote a book entitled _Pyrrhonean

Tropes_, and Plutarch one called _The Ten ([Greek: topoi]) Topes

of Pyrrho_.[8] Both of these latter works are lost.

[8] Fabricius on _Hyp._ I. 36.

All authorities unite in attributing to Aenesidemus the work of

systematizing and presenting to the world the ten Tropes of

[Greek: epochê]. He was the first to conceive the project of

opposing an organized philosophical system of Pyrrhonism to the

dogmatism of his contemporaries.[1] Moreover, the fact that

Diogenes introduces the Tropes into his life of Pyrrho, does not

necessarily imply that he considered Pyrrho their author, for

Diogenes invariably combines the teachings of the followers of a

movement with those of the founders themselves; he gives these

Tropes after speaking of Aenesidemus' work entitled _Pyrrhonean

Hypotyposes_, and apparently quotes from this book, in giving at

least a part of his presentation of Pyrrhonism, either directly

or through, the works of others. Nietzsche proposes a correction

of the text of Diogenes IX. 11, 79, which would make him quote the

Tropes from a book by Theodosius,[2] author of a commentary on

the works of Theodas. No writer of antiquity claims for the

Tropes an older source than the books of Aenesidemus, to whom

Aristocles also attributes them.[3] They are not mentioned in

Diogenes' life of Timon, the immediate disciple of Pyrrho.

Cicero has no knowledge of them, and does not refer to them in

his discussion of Scepticism.

[2] Brochard _Op. cit._ 254, Note 4.

[3] Aristocles _Eus. praep. ev._ XIV. 18. 8.

Aenesidemus was undoubtedly the first to formulate these Tropes,

but many things tend to show that they resulted, in reality,

from the gradual classification of the results of the teachings

of Pyrrho, in the subsequent development of thought from his own

time to that of Aenesidemus. The ideas contained in the Tropes

were not original with Aenesidemus, but are more closely

connected with the thought of earlier times. The decidedly

empirical character of the Tropes proves this connection, for

the eight Tropes of Aetiology, which were original with

Aenesidemus, bear a far stronger dialectic stamp, thus showing a

more decided dialectic influence of the Academy than is found in

the Tropes of [Greek: epochê]. Many of the illustrations given

of the Tropes also, testify to a time of greater antiquity than

that of Aenesidemus. The name Trope was well known in ancient

times, and the number ten reminds us of the ten opposing

principles of Pythagoras, and the ten categories of Aristotle,

the fourth of which was the same as the eighth Trope. The

terminology, however, with very few exceptions, points to a

later period than that of Pyrrho. Zeller points out a number of

expressions in both Diogenes' and Sextus' exposition of the

Tropes, which could not date back farther than the time of

Aenesidemus.[1] One of the most striking features of the whole

presentation of the Tropes, especially as given by Sextus, is

their mosaic character, stamping them not as the work of one

person, but as a growth, and also an agglutinous growth, lacking

very decidedly the symmetry of thought that the work of one mind

would have shown.

[1] Zeller _Op. cit._ p. 25.

At the time of the separation of Pyrrhonism from the Academy, no

other force was as strong in giving life to the school as the

systematic treatment by Aenesidemus of the Ten Tropes of [Greek:

epochê]. The reason of this is evident. It was not that the

ideas of the Sceptical Tropes were original with Aenesidemus,

but because a definite statement of belief is always a far more

powerful influence than principles which are vaguely understood

and accepted. There is always, however, the danger to the

Sceptic, in making a statement even of the principles of

Scepticism, that the psychological result would be a dogmatic

tendency of mind, as we shall see later was the case, even with

Aenesidemus himself. That the Sceptical School could not escape

the accusation of dogmatizing, from the Dogmatics, even in

stating the grounds of their Scepticism, we know from

Diogenes.[1] To avoid this dogmatic tendency of the ten Tropes,

Sextus makes the frequent assertion that he does not affirm

things to be absolutely true, but states them as they appear to

him, and that they may be otherwise from what he has said.[2]

[1] Diog. IX. 11, 102.

[2] _Hyp._ I. 4, 24.

Sextus tells us that "Certain Tropes, ten in number, for

producing the state of [Greek: epochê] have been handed down

from the older Sceptics."[1] He refers to them in another work

as the "Tropes of Aenesidemus."[2] There is no evidence that the

substance of these Tropes was changed after the time of

Aenesidemus, although many of the illustrations given by Sextus

must have been of a later date, added during the two centuries

that elapsed between the time of Aenesidemus and Sextus. In

giving these Tropes Sextus does not claim to offer a systematic

methodical classification, and closes his list of them, in their

original concise form, with the remark, "We make this order

ourselves."[3] The order is given differently by Diogenes, and

also by Favorinus.[4] The Trope which Sextus gives as the tenth

is the fifth given by Diogenes, the seventh by Sextus is the

eighth given by Diogenes, the fifth by Sextus, the seventh by

Diogenes, the tenth by Diogenes, the eighth by Sextus. Diogenes

says that the one he gives as the ninth Favorinus calls the

eighth, and Sextus and Aenesidemus the tenth. This statement

does not correspond with the list of the Tropes which Sextus

gives, proving that Diogenes took some other text than that of

Sextus as his authority.[5] The difference in the order of the

Tropes shows, also, that the order was not considered a matter

of great importance. There is a marked contrast in the spirit of

the two presentations of the Tropes given by Sextus and

Diogenes. The former gives them not only as an orator, but as

one who feels that he is defending his own cause, and the school

of which he is the leader, against mortal enemies, while

Diogenes relates them as an historian.

Pappenheim tries to prove[1] that Aenesidemus originally gave

only nine Tropes in his _Pyrrhonean Hypotyposes_, as Aristocles

mentions only nine in referring to the Tropes of Aenesidemus,

and that the tenth was added later. Had this been the case,

however, the fact would surely have been mentioned either by

Diogenes or Sextus, who both refer to the ten Tropes of

Aenesidemus.

The Tropes claim to prove that the character of phenomena is so

relative and changeable, that certain knowledge cannot be based

upon them, and as we have shown, there is no other criterion of

knowledge for the Sceptic than phenomena.[2] All of the Tropes,

except the tenth, are connected with sense-perception, and

relate to the difference of the results obtained through the

senses under different circumstances. They may be divided into

two classes, _i.e._, those based upon differences of our

physical organism, and those based upon external differences. To

the first class belong the first, second, third and fourth; to

the second class, the fifth, sixth, seventh and eighth, and also

the ninth. The eighth, or that of relation, is applied

objectively both by Sextus and Diogenes in their treatment of

the Tropes, and is not used for objects of thought alone, but

principally to show the relation of outward objects to each

other. The tenth is the only one which has a moral significance,

and it has also a higher subjective value than the others; it

takes its arguments from an entirely different sphere of

thought, and deals with metaphysical and religious

contradictions in opinion, and with the question of good and

evil. That this Trope is one of the oldest, we know from its

distinct mention in connection with the foundation theories of

Pyrrho, by Diogenes.[3] In treating of the subjective reasons

for doubt as to the character of external reality, the Sceptics

were very near the denial of all outward reality, a point,

however, which they never quite reached.

[2] _Hyp._ I. 22.

[3] Diog. IX. 11, 61.

There is evidently much of Sextus' own thought mixed with the

illustrations of the Tropes, but it is impossible to separate

the original parts from the material that was the common

property of the Sceptical School. Many of these illustrations

show, however, perfect familiarity with the scientific and

medical teachings of the time. Before entering upon his

exposition of the Tropes, Sextus gives them in the short concise

form in which they must first have existed[1]--

(i) Based upon the variety of animals.

(ii) Based upon the differences between men.

(iii) Based upon differences in the constitution of

the sense organs.

(iv) Based upon circumstances.

(v) Based upon position, distance and place.

(vi) Based upon mixtures.

(vii) Based upon the quantities and constitutions

of objects.

(viii) Relation.

(ix) Based upon frequency or rarity of occurences.

(x) Based upon systems, customs and laws,

mythical beliefs, and dogmatic opinions.

[1] _Hyp._ I. 36-38.

Although Sextus is careful not to dogmatise regarding the

arrangement of the Tropes, yet there is in his classification of

them a regular gradation, from the arguments based upon

differences in animals to those in man, first considering the

latter in relation to the physical constitution, and then to

circumstances outside of us, and finally the treatment of

metaphysical and moral differences.

_The First Trope_.[1] That the same mental representations are

not found in different animals, may be inferred from their

differences in constitution resulting from their different

origins, and from the variety in their organs of sense. Sextus

takes up the five senses in order, giving illustrations to prove

the relative results of the mental representations in all of

them, as for example the subjectivity of color[2] and sound.[3]

All knowledge of objects through the senses is relative and not

absolute. Sextus does not, accordingly, confine the

impossibility of certain knowledge to the qualities that Locke

regards as secondary, but includes also the primary ones in this

statement.[4] The form and shape of objects as they appear to us

may be changed by pressure on the eyeball. Furthermore, the

character of reflections in mirrors depend entirely on their

shape, as the images in concave mirrors are very different from

those in convex ones; and so in the same way as the eyes of

animals are of different shapes, and supplied with different

fluids, the ideas of dogs, fishes, men and grasshoppers must be

very different.[5]

In discussing the mental representations of animals of different

grades of intelligence, Sextus shows a very good comprehension

of the philogenetic development of the organs of sense, and

draws the final conclusion that external objects are regarded

differently by animals, according to their difference in

constitution.[1] These differences in the ideas which different

animals have of the same objects are demonstrated by their

different tastes, as the things desired by some are fatal to

others.[2] The practical illustrations given of this result show

a familiarity with natural history, and cognizance of the tastes

and habits of many animals,[3] but were probably few of them

original with Sextus, unless perhaps in their application; that

this train of reasoning was the common property of the Sceptic

School, we know from the fact that Diogenes begins his

exposition of the first Trope in a way similar to that of

Sextus.[4] His illustrations are, however, few and meagre

compared with those of Sextus, and the scientific facts used by

both of them may mostly be found in other authors of antiquity

given in a similar way.[5] The logical result of the reasoning

used to explain the first Trope, is that we cannot compare the

ideas of the animals with each other, nor with our own; nor can

we prove that our ideas are more trustworthy than those of the

animals.[6] As therefore an examination of ideas is impossible,

any decided opinion about their trustworthiness is also

impossible, and this Trope leads to the suspension of judgment

regarding external objects, or to [Greek: epochê.][7]

After reaching this conclusion, Sextus introduces a long chapter

to prove that animals can reason. There is no reference to this

in Diogenes, but there is other testimony to show that it was a

favourite line of argument with the Sceptics.[1] Sextus,

however, says that his course of reasoning is different from

that of most of the Sceptics on the subject,[2] as they usually

applied their arguments to all animals, while he selected only

one, namely the dog.[3] This chapter is full of sarcastic

attacks on the Dogmatics, and contains the special allusion to

the Stoics as the greatest opponents of the Sceptics, which has

been before referred to.[4]

Sextus claims with a greater freedom of diction than in some

apparently less original chapters, and with a wealth of special

illustrations, that the dog is superior to man in acuteness of

perception,[5] that he has the power of choice, and possesses an

art, that of hunting,[6] and, also, is not deprived of

virtue,[7] as the true nature of virtue is to show justice to

all, which the dog does by guarding loyally those who are kind

to him, and keeping off those who do evil.[8] The reasoning

power of this animal is proved by the story taken from

Chrysippus, of the dog that came to a meeting of three roads in

following a scent. After seeking the scent in vain in two of the

roads, he takes the third road without scenting it as a result

of a quick process of thought, which proves that he shares in

the famous dialectic of Chrysippus,[9] the five forms of [Greek:

_anapodeiktoi logoi_,] of which the dog chooses the fifth.

Either _A_ or _B_ or _C_, not _A_ or _B,_ therefore _C_.

The dog and other irrational animals may also possess spoken

language, as the only proof that we have to the contrary, is the

fact that we cannot understand the sounds that they make.[1] We

have an example in this chapter of the humor of Sextus, who

after enlarging on the perfect character of the dog, remarks,

"For which reason it seems to me some philosophers have honoured

themselves with the name of this animal,"[2] thus making a

sarcastic allusion to the Cynics, especially Antisthenes.[3]

_The Second Trope_. Passing on to the second Trope, Sextus aims

to prove that even if we leave the differences of the mental

images of animals out of the discussion, there is not a

sufficient unanimity in the mental images of human beings to

allow us to base any assertions upon them in regard to the

character of external objects.[1] He had previously announced

that he intended to oppose the phenomenal to the intellectual

"in any way whatever,"[2] so he begins here by referring to the

two parts of which man is said to be composed, the soul and the

body, and proceeds to discuss the differences among men in

sense-perception and in opinion.[3] Most of the illustrations

given of differences in sense-perception are medical ones; of

the more general of these I will note the only two which are

also given by Diogenes in his exposition of this Trope,[4] viz.,

Demophon, Alexander's table waiter, who shivered in the sun, and

Andron the Argive, who was so free from thirst that he travelled

through the desert of Libya without seeking a drink. Some have

reasoned from the presence of the first of these illustrations

in the exposition of the Tropes, that a part of this material at

least goes back to the time of Pyrrho, as Pyrrho from his

intimacy with Alexander, when he accompanied him to India, had

abundant opportunities to observe the peculiarities of his

servant Demophon.[5] The illustration of Andron the Argive is

taken from Aristotle, according to Diogenes.[6]

phil._, Paris 1885, No. 5; Victor Brochard, p. 521.

[6] Diog. IX. 11, 81.

Passing on to differences of opinion, we have another example of

the sarcastic humor of Sextus, as he refers to the [Greek:

physiognômonikê sophia][1] as the authority for believing that

the body is a type of the soul. As the bodies of men differ, so

the souls also probably differ. The differences of mind among

men is not referred to by Diogenes, except in the general

statement that they choose different professions; while Sextus

elaborates this point, speaking of the great differences in

opposing schools of philosophy, and in the objects of choice and

avoidance, and sources of pleasure for different men.[2] The

poets well understand this marked difference in human desires,

as Homer says,

"One man enjoys this, another enjoys that."

Sextus also quotes the beautiful lines of Pindar,[3]

"One delights in getting honours and crowns through

stormfooted horses,

Others in passing life in rooms rich in gold,

Another safe travelling enjoys, in a swift ship,

on a wave of the sea."

[2] _Hyp._ I. 87-89.

[3] _Hyp._ I. 86.

_The Third Trope_. The third Trope limits the argument to the

sense-perceptions of one man, a Dogmatic, if preferred, or to

one whom the Dogmatics consider wise,[1] and states that as the

ideas given by the different sense organs differ radically in a

way that does not admit of their being compared with each other,

they furnish no reliable testimony regarding the nature of

objects.[2] "Each of the phenomena perceived by us seems to

present itself in many forms, as the apple, smooth, fragrant

brown and sweet." The apple was evidently the ordinary example

given for this Trope, for Diogenes uses the same, but in a much

more condensed form, and not with equal understanding of the

results to be deduced from it.[3] The consequence of the

incompatibility of the mental representations produced through

the several sense organs by the apple, may be the acceptance of

either of the three following propositions: (i) That only those

qualities exist in the apple which we perceive. (ii) That more

than these exist. (iii) That even those perceived do not

exist.[4] Accordingly, any experience which can give rise to

such different views regarding outward objects, cannot be relied

upon as a testimony concerning them.

[3] Diog. IX. 11 81.

[4] _Hyp._ I. 99.

The non-homogeneous nature of the mental images connected with

the different sense organs, as presented by Sextus, reminds us

of the discussion of the same subject by Berkeley in his _Theory

of Vision_.

Sextus says that a man born with less than the usual number of

senses, would form altogether different ideas of the external

world than those who have the usual number, and as our ideas of

objects depend on our mental images, a greater number of sense

organs would give us still different ideas of outward

reality.[1] The strong argument of the Stoics against such

reasoning as this, was their doctrine of pre-established harmony

between nature and the soul, so that when a representation is

produced in us of a real object, a [Greek: katalêptikê

phantasia],[2] by this representation the soul grasps a real

existence. There is a [Greek: logos] in us which is of the same

kind, [Greek: syngenos], or in relation to all nature. This

argument of pre-established harmony between the faculties of the

soul and the objects of nature, is the one that has been used in

all ages to combat philosophical teaching that denies that we

apprehend the external world as it is. It was used against Kant

by his opponents, who thought in this way to refute his

teachings.[3] The Sceptics could not, of course, accept a theory

of nature that included the soul and the external world in one

harmonious whole, but Sextus in his discussion of the third

Trope does not refute this argument as fully as he does later in

his work against logic.[4] He simply states here that

philosophers themselves cannot agree as to what nature is, and

furthermore, that a philosopher himself is a part of the

discord, and to be judged, rather than being capable of judging,

and that no conclusion can be reached by those who are

themselves an element of the uncertainty.[5]

[5] _Hyp._ I. 98-99.

_The Fourth Trope_. This Trope limits the argument to each

separate sense, and the effect is considered of the condition of

body and mind upon sense-perception in relation to the several

sense-organs.[1] The physical states which modify

sense-perception are health and illness, sleeping and waking,

youth and age, hunger and satiety, drunkenness and sobriety. All

of these conditions of the body entirely change the character of

the mental images, producing different judgments of the color,

taste, and temperature of objects, and of the character of

sounds. A man who is asleep is in a different world from one

awake, the existence of both worlds being relative to the

condition of waking and sleeping.[2]

The subjective states which Sextus mentions here as modifying

the character of the mental representations are hating or

loving, courage or fear, sorrow or joy, and sanity or

insanity.[3] No man is ever twice in exactly the same condition

of body or mind, and never able to review the differences of his

ideas as a sum total, for those of the present moment only are

subject to careful inspection.[4] Furthermore, no one is free

from the influence of all conditions of body or mind, so that he

can be unbiassed to judge his ideas, and no criterion can be

established that can be shown to be true, but on the contrary,

whatever course is pursued on the subject, both the criterion

and the proof will be thrown into the _circulus in probando_,

for the truth of each rests on the other.[5]

Diogenes gives in part the same illustrations of this Trope, but

in a much more condensed form. The marked characteristic of this

train of reasoning is the attempt to prove that abnormal

conditions are also natural. In referring at first to the

opposing states of body and mind, which so change the character

of sense-perception, Sextus classifies them according to the

popular usage as [Greek: kata physin] and [Greek: para physin].

This distinction was an important one, even with Aristotle, and

was especially developed by the Stoics[1] in a broader sense

than referring merely to health and sickness. The Stoics,

however, considered only normal conditions as being according to

nature. Sextus, on the contrary, declares that abnormal states

are also conditions according to nature,[2] and just as those

who are in health are in a state that is natural to those who

are in health, so also those not in health are in a state that

is natural to those not in health, and in some respects

according to nature. Existence, then, and non-existence are not

absolute, but relative, and the world of sleep as really exists

for those who are asleep as the things that exist in waking

exist, although they do not exist in sleep.[3] One mental

representation, therefore, cannot be judged by another, which is

also in a state of relation to existing physical and mental

conditions. Diogenes states this principle even more decidedly

in his exposition of this Trope. "The insane are not in a

condition opposed to nature; why they more than we? For we also

see the sun as if it were stationary."[4] Furthermore, in

different periods of life ideas differ. Children are fond of

balls and hoops, while those in their prime prefer other things,

and the aged still others.[5] The wisdom contained in this Trope

in reference to the relative value of the things most sought

after is not original with Sextus, but is found in the more

earnest ethical teachings of older writers. Sextus does not,

however, draw any moral conclusions from this reasoning, but

only uses it as an argument for [Greek: epochê].

_The Fifth Trope_. This Trope leaves the discussion of the

dependence of the ideas upon the physical nature, and takes up

the influence of the environment upon them. It makes the

difference in ideas depend upon the position, distance, and

place of objects, thus taking apparently their real existence

for granted. Things change their form and shape according to the

distance from which they are observed, and the position in which

they stand.[1]

The same light or tone alters decidedly in different

surroundings. Perspective in paintings depends on the angle at

which the picture is suspended.[2] With Diogenes this Trope is

the seventh,[3] and his exposition of it is similar, but as

usual, shorter. Both Sextus and Diogenes give the

illustration[4] of the neck of the dove differing in color in

different degrees of inclination, an illustration used by

Protagoras also to prove the relativity of perception by the

senses. "The black neck of the dove in the shade appears black,

but in the light sunny and purple."[5] Since, then, all

phenomena are regarded in a certain place, and from a certain

distance, and according to a certain position, each of which

relations makes a great difference with the mental images, we

shall be obliged also by this Trope to come to the reserving of

the opinion.[6]

_The Sixth Trope_. This Trope leads to [Greek: epochê] regarding

the nature of objects, because no object can ever be presented

to the organs of sense directly, but must always be perceived

through some medium, or in some mixture.[1] This mixture may be

an outward one, connected with the temperature, or the rarity of

the air, or the water[2] surrounding an object, or it may be a

mixture resulting from the different humors of the

sense-organs.[3] A man with the jaundice, for example, sees

colors differently from one who is in health. The illustration

of the jaundice is a favorite one with the Sceptics. Diogenes

uses it several times in his presentation of Scepticism, and it

occurs in Sextus' writings in all, as an illustration, in eight

different places.[4] The condition of the organ of the [Greek:

hêgemonikon], or the ruling faculty, may also cause mixtures.

Pappenheim thinks that we have here Kant's idea of _a priori_,

only on a materialistic foundation.[5] A careful consideration

of the passage, however, shows us that Sextus' thought is more

in harmony with the discoveries of modern psychiatry than with

the philosophy of Kant. If the sentence, [Greek: isôs de kai

autê (hê dianoia) epimixian tina idian poieitai pros ta hypo tôn

aisthêseôn anangellomena],[6] stood alone, without further

explanation, it might well refer to _a priori_ laws of thought,

but the explanation which follows beginning with "because" makes

that impossible.[7] "Because in each of the places where the

Dogmatics think that the ruling faculty is, we see present

certain humors, which are the cause of mixtures." Sextus does

not advance any opinion as to the place of the ruling faculty in

the body, which is, according to the Stoics, the principal part

of the soul, where ideas, desires, and reasoning originate,[8]

but simply refers to the two theories of the Dogmatics, which

claim on the one hand that it is in the brain, and on the other

that it is in the heart.[9] This subject he deals with more

fully in his work against logic.[10] As, however, he bases his

argument, in discussing possible intellectual mixtures in

illustration of the sixth Trope, entirely on the condition of

the organ of the intellect, it is evident that his theory of the

soul was a materialistic one.

_The Seventh Trope_. This Trope, based upon the quantities and

compositions of objects, is illustrated by examples of different

kinds of food, drink, and medicine, showing the different

effects according to the quantity taken, as the harmfulness and

the usefulness of most things depend on their quantity. Things

act differently upon the senses if applied in small or large

quantities, as filings of metal or horn, and separate grains of

sand have a different color and touch from the same taken in the

form of a solid.[1] The result is that ideas vary according to

the composition of the object, and this Trope also brings to

confusion the existence of outward objects, and leads us to

reserve our opinion in regard to them.[2] This Trope is

illustrated by Diogenes with exceeding brevity.[3]

_The Eighth Trope_. The Trope based upon relation contains, as

Sextus rightly remarks, the substance of the other nine,[1] for

the general statement of the relativity of knowledge includes

the other statements made. The prominence which Sextus gave this

Trope in his introduction to the ten Tropes leads one to expect

here new illustrations and added[2] arguments for [Greek:

epochê]. We find, however, neither of these, but simply a

statement that all things are in relation in one of two ways,

either directly, or as being a part of a difference. These two

kinds of relation are given by Protagoras, and might have been

used to good purpose in the introduction to the Tropes, or at

the end, to prove that all the others were really subordinate to

the eighth. The reasoning is, however simply applied to the

relation of objects to each other, and nothing is added that is

not found elsewhere where as an argument for [Greek: epochê].[3]

This Trope is the tenth by Diogenes, and he strengthens his

reasoning in regard to it, by a statement that Sextus does not

directly make, _i.e._, that everything is in relation to the

understanding.[4]

_The Ninth Trope_. This is based upon the frequency and rarity

of events, and refers to some of the phenomena of nature, such

as the rising of the sun, and the sea, as no longer a source of

astonishment, while a comet or an earthquake are wonders to

those not accustomed to them.[1] The value of objects also

depends on their rarity, as for example the value of gold.[2]

Furthermore, things may be valuable at one time, and at another

not so, according to the frequency and rarity of the

occurrence.[3] Therefore this Trope also leads to [Greek:

epochê]. Diogenes gives only two illustrations to this Trope,

that of the sun and the earthquake.[4]

_The Tenth Trope_. We have already remarked on the difference in

the character of the tenth Trope, dealing as it does, not with

the ideas of objects, like the other nine Tropes, but with

philosophical and religious opinions, and questions of right and

wrong. It was the well-known aim of the Sceptics to submit to

the laws and customs of the land where they were found, and to

conform to certain moral teachings and religious ceremonies;

this they did without either affirming or denying the truth of

the principles upon which these teachings were based,[1] and

also without any passion or strong feeling in regard to them,[2]

as nothing in itself can be proved to be good or evil. The tenth

Trope accordingly, brings forward contradictions in customs,

laws, and the beliefs of different lands, to show that they are

also changeable and relative, and not of absolute worth. The

foundation-thought of this Trope is given twice by Diogenes,

once as we have before stated in his introduction[3] to the life

of Pyrrho, and also as one of the Tropes.[4] As it is apparently

one of the oldest of the Tropes, it would naturally be much used

in discussing with the Stoics, whose philosophy had such a wide

ethical significance, and must also have held an important place

in the Sceptical School in all metaphysical and philosophical

discussions. The definition[5] in the beginning of Sextus'

exposition of this Trope Fabricius thinks was taken from

Aristotle, of schools, laws, customs, mythical beliefs and

dogmatic opinions,[6] and the definition which Diogenes gives of

law in his life of Plato[7] is similar. Pappenheim, however,

thinks they were taken from the Stoics, perhaps from

Chrysippus.[8] The argument is based upon the differences in

development of thought, as affecting the standpoint of judgment

in philosophy, in morals, and religion, the results of which we

find in the widely opposing schools of philosophy, in the

variety in religious belief, and in the laws and customs of

different countries. Therefore the decisions reached in the

world of thought leave us equally in doubt regarding the

absolute value of any standards, with those obtained through

sense-perception, and the universal conflict of opinion

regarding all questions of philosophy and ethics leads us also

according to this Trope to the reserving of the opinion.[9] This

Trope is the fifth as given by Diogenes, who placed it directly

after the first four which relate more especially to human

development,[10] while Sextus uses it as the final one, perhaps

thinking that an argument based upon the higher powers of man

deserves the last place, or is the summation of the other

arguments.

Following the exposition of the ten Tropes of the older

Sceptics, Sextus gives the five Tropes which he attributes to

the "later Sceptics."[1] Sextus nowhere mentions the author of

these Tropes. Diogenes, however, attributes them to Agrippa, a

man of whom we know nothing except his mention of him. He was

evidently one of the followers of Aenesidemus, and a scholar of

influence in the Sceptical School, who must have himself had

disciples, as Diogenes says, [Greek: hoi peri Agrippan][2] add

to these tropes other five tropes, using the plural verb.

Another Sceptic, also mentioned by Diogenes, and a man unknown

from other sources, named some of his books after Agrippa.[3]

Agrippa is not given by Diogenes in the list of the leaders of

the Sceptical School, but[4] his influence in the development of

the thought of the School must have been great, as the

transition from the ten Tropes of the "older Sceptics" to the

five attributed to Agrippa is a marked one, and shows the

entrance into the school of a logical power before unknown in

it. The latter are not a reduction of the Tropes of Aenesidemus,

but are written from an entirely different standpoint. The ten

Tropes are empirical, and aim to furnish objective proofs of the

foundation theories of Pyrrhonism, while the five are rather

rules of thought leading to logical proof, and are dialectic in

their character. We find this distinction illustrated by the

different way in which the Trope of relativity is treated in the

two groups. In the first it points to an objective relativity,

but with Agrippa to a general subjective logical principle. The

originality of the Tropes of Agrippa does not lie in their

substance matter, but in their formulation and use in the

Sceptical School. These methods of proof were, of course, not

new, but were well known to Aristotle, and were used by the

Sceptical Academy, and probably also by Timon,[5] while the

[Greek: pros ti] goes back at least to Protagoras. The five

Tropes are as follows.

(i) The one based upon discord.

(ii) The _regressus in infinitum_.

(iii) Relation.

(iv) The hypothetical.

(v) The _circulus in probando_.

Two of these are taken from the old list, the first and the

third, and Sextus says that the five Tropes are intended to

supplement the ten Tropes, and to show the audacity of the

Dogmatics in a variety of ways.[6] The order of these Tropes is

the same with Diogenes as with Sextus, but the definitions of

them differ sufficiently to show that the two authors took their

material from different sources. According to the first one

everything in question is either sensible or intellectual, and

in attempting to judge it either in life, practically, or "among

philosophers," a position is developed from which it is

impossible to reach a conclusion.[7] According to the second,

every proof requires another proof, and so on to infinity, and

there is no standpoint from which to begin the reasoning.[8]

According to the third, all perceptions are relative, as the

object is colored by the condition of the judge, and the

influence of other things around it.[9] According to the fourth,

it is impossible to escape from the _regressus in infinitum_ by

making a hypothesis the starting point, as the Dogmatics attempt

to do.[10] And the fifth, or the _circulus in probando_, arises

when that which should be the proof needs to be sustained by the

thing to be proved.

Sextus claims that all things can be included in these Tropes,

whether sensible or intellectual.[1] For whether, as some say,

only the things of sense are true, or as others claim, only

those of the understanding, or as still others contend, some

things both of sense and understanding are true, a discord must

arise that is impossible to be judged, for it cannot be judged

by the sensible, nor by the intellectual, for the things of the

intellect themselves require a proof; accordingly, the result of

all reasoning must be either hypothetical, or fall into the

_regressus in infinitum_ or the _circulus in probando_.[2] The

reference above to some who say that only the things of sense

are true, is to Epicurus and Protagoras; to some that only the

things of thought are true, to Democritus and Plato; and to

those that claimed some of both to be true, to the Stoics and

the Peripatetics.[3] The three new Tropes added by Agrippa have

nothing to do with sense-perception, but bear entirely upon the

possibility of reasoning, as demanded by the science of logic,

in contrast to the earlier ones which related almost entirely,

with the exception of the tenth, to material objects. Sextus

claims that these five Tropes also lead to the suspension of

judgment,[4] but their logical result is rather the dogmatic

denial of all possibility of knowledge, showing as Hirzel has

well demonstrated, far more the influence of the New Academy

than the spirit of the Sceptical School.[5] It was the

standpoint of the older Sceptics, that although the search for

the truth had not yet succeeded, yet they were still seekers,

and Sextus claims to be faithful to this old aim of the

Pyrrhonists. He calls himself a seeker,[6] and in reproaching

the New Academy for affirming that knowledge is impossible,

Sextus says, "Moreover, we say that our ideas are equal as

regards trustworthiness and untrustworthiness."[7] The ten

Tropes claim to establish doubt only in regard to a knowledge of

the truth, but the five Tropes of Agrippa aim to logically prove

the impossibility of knowledge. It is very strange that Sextus

does not see this decided contrast in the attitude of the two

sets of Tropes, and expresses his approval of those of Agrippa,

and makes more frequent use of the fifth of these, [Greek: ho

diallêlos], in his subsequent reasoning than of any other

argument.[8]

We find here in the Sceptical School, shortly after the time of

Aenesidemus, the same tendency to dogmatic teaching that--so far

as the dim and shadowy history of the last years of the New

Academy can be unravelled, and the separation of Pyrrhonism can

be understood, at the time that the Academy passed over into

eclecticism--was one of the causes of that separation.

It is true that the Tropes of Agrippa show great progress in the

development of thought. They furnish an organisation of the

School far superior to what went before, placing the reasoning

on the firm basis of the laws of logic, and simplifying the

amount of material to be used. In a certain sense Saisset is

correct in saying that Agrippa contributed more than any other

in completing the organisation of Scepticism,[1] but it is not

correct when we consider the true spirit of Scepticism with

which the Tropes of Agrippa were not in harmony. It was through

the very progress shown in the production of these Tropes that

the school finally lost the strength of its position.

Not content with having reduced the number of the Tropes from

ten to five, others tried to limit the number still further to

two.[2] Sextus gives us no hint of the authorship of the two

Tropes. Ritter attributes them to Menodotus and his followers,

and Zeller agrees with that opinion,[3] while Saisset thinks

that Agrippa was also the author of these,[4] which is a strange

theory to propound, as some of the material of the five is

repeated in the two, and the same man could certainly not appear

as an advocate of five, and at the same time of two Tropes.

The two Tropes are founded on the principle that anything must

be known through itself or through something else. It cannot be

known through itself, because of the discord existing between

all things of the senses and intellect, nor can it be known

through something else, as then either the _regressus in

infinitum_ or the _circulus in probando_ follow.[1] Diogenes

Laertius does not refer to these two Tropes.

In regard to all these Tropes of the suspension of judgment,

Sextus has well remarked in his introduction to them, that they

are included in the eighth, or that of relation.[2]

[1] _Hyp._ I. 178-179.

[2] _Hyp._ I. 39.

_The Tropes of Aetiology_. The eight Tropes against causality

belong chronologically before the five Tropes of Agrippa, in the

history of the development of sceptical thought. They have a

much closer connection with the spirit of Scepticism than the

Tropes of Agrippa, including, as they do, the fundamental

thought of Pyrrhonism, _i.e._, that the phenomena do not reveal

the unknown.

The Sceptics did not deny the phenomena, but they denied that

the phenomena are signs capable of being interpreted, or of

revealing the reality of causes. It is impossible by a research

of the signs to find out the unknown, or the explanation of

things, as the Stoics and Epicureans claim. The theory of

Aenesidemus which lies at the foundation of his eight Tropes

against aetiology, is given to us by Photius as follows:[1]

"There are no visible signs of the unknown, and those who

believe in its existence are the victims of a vain illusion."

This statement of Aenesidemus is confirmed by a fuller

explanation of it given later on by Sextus.[2] If phenomena are

not signs of the unknown there is no causality, and a refutation

of causality is a proof of the impossibility of science, as all

science is the science of causes, the power of studying causes

from effects, or as Sextus calls them, phenomena.

It is very noticeable to any one who reads the refutation of

causality by Aenesidemus, as given by Sextus,[3] that there is

no reference to the strongest argument of modern Scepticism,

since the time of Hume, against causality, namely that the

origin of the idea of causality cannot be so accounted for as to

justify our relying upon it as a form of cognition.[4]

[2] _Adv. Math._ VIII. 207.

[3] _Hyp._ I. 180-186.

[4] Ueberweg _Op. cit._ p. 217.

The eight Tropes are directed against the possibility of

knowledge of nature, which Aenesidemus contested against in all

his Tropes, the ten as well as the eight.[1] They are written

from a materialistic standpoint. These Tropes are given with

illustrations by Fabricius as follows:

I. Since aetiology in general refers to things that are unseen,

it does not give testimony that is incontestable in regard to

phenomena. For example, the Pythagoreans explain the distance of

the planets by a musical proportion.

II. From many equally plausible reasons which might be given for

the same thing, one only is arbitrarily chosen, as some explain

the inundation of the Nile by a fall of snow at its source,

while there could be other causes, as rain, or wind, or the

action of the sun.

III. Things take place in an orderly manner, but the causes

presented do not show any order, as for example, the motion of

the stars is explained by their mutual pressure, which does not

take into account the order that reigns among them.

IV. The unseen things are supposed to take place in the same way

as phenomena, as vision is explained in the same way as the

appearance of images in a dark room.

V. Most philosophers present theories of aetiology which agree

with their own individual hypotheses about the elements, but not

with common and accepted ideas, as to explain the world by atoms

like Epicurus, by homoeomeriae like Anaxagoras, or by matter and

form like Aristotle.

VI. Theories are accepted which agree with individual

hypotheses, and others equally probable are passed by, as

Aristotle's explanation of comets, that they are a collection of

vapors near the earth, because that coincided with his theory of

the universe.

VII. Theories of aetiology are presented which conflict not only

with individual hypotheses, but also with phenomena, as to admit

like Epicurus an inclination or desire of the soul, which was

incompatible with the necessity which he advocated.

VIII. The inscrutable is explained by things equally

inscrutable, as the rising of sap in plants is explained by the

attraction of a sponge for water, a fact contested by some.[2]

[1] _Hyp._ I. 98.

[2] _Hyp._ I. 180-186; Fabricius, Cap. XVII. 180 z.

Diogenes does not mention these Tropes in this form, but he

gives a _resumé_ of the general arguments of the Sceptics

against aetiology,[1] which has less in common with the eight

Tropes of Aenesidemus, than with the presentation of the subject

by Sextus later,[2] when he multiplies his proofs exceedingly to

show [Greek: mêden einai aition]. Although the Tropes of

Aenesidemus have a dialectic rather than an objective character,

it would not seem that he made the distinction, which is so

prominent with Sextus, between the signs [Greek: hypomnêstika]

and [Greek: endeiktika],[3] especially as Diogenes sums up his

argument on the subject with the general assertion, [Greek:

Sêmeion ouk einai],[4] and proceeds to introduce the logical

consequence of the denial of aetiology. The summing up of the

Tropes of Aenesidemus is given as follows, in the _Hypotyposes_,

by Sextus:--"A cause in harmony with all the sects of

philosophy, and with Scepticism, and with phenomena, is perhaps

not possible, for the phenomena and the unknown altogether

disagree."[5]

It is interesting to remark in connection with the seventh of

these Tropes, that Aenesidemus asserts that causality has only a

subjective value, which from his materialistic standpoint was an

argument against its real existence, and the same argument is

used by Kant to prove that causality is a necessary condition of

thought.[6]

Chaignet characterises the Tropes of Aenesidemus as false and

sophistical,[7] but as Maccoll has well said, they are

remarkable for their judicious and strong criticism, and are

directed against the false method of observing facts through the

light of preconceived opinion.[8] They have, however, a stronger

critical side than sceptical, and show the positive tendency of

the thought of Aenesidemus.

CHAPTER IV.

_Aenesidemus and the Philosophy of Heraclitus._

A paragraph in the First Book of the _Hypotyposes_ which has

given rise to much speculation and many different theories, is

the comparison which Sextus makes of Scepticism with the

philosophy of Heraclitus.[1] In this paragraph the statement is

made that Aenesidemus and his followers, [Greek: hoi peri ton

Ainêsidêmon], said that Scepticism is the path to the philosophy

of Heraclitus, because the doctrine that contradictory

predicates appear to be applicable to the same thing, leads the

way to the one that contradictory predicates are in reality

applicable to the same thing.[2] [Greek: hoi peri ton

Ainêsidêmon elegon hodon einai tên skeptikên agôgên epi tên

Hêrakleiteion philosophian, dioti proêgeitai tou tanantia peri

to auto hyparchein to tanantia peri to auto phainesthai]. As the

Sceptics say that contradictory predicates appear to be

applicable to the same thing, the Heraclitans come from this to

the more positive doctrine that they are in reality so.[3]

[1] _Hyp._ I. 210.

[2] _Hyp._ I. 210.

[3] _Hyp._ I. 210.

This connection which Aenesidemus is said to have affirmed

between Scepticism and the philosophy of Heraclitus is earnestly

combated by Sextus, who declares that the fact that

contradictory predicates appear to be applicable to the same

thing is not a dogma of the Sceptics, but a fact which presents

itself to all men, and not to the Sceptics only. No one for

instance, whether he be a Sceptic or not, would dare to say that

honey does not taste sweet to those in health, and bitter to

those who have the jaundice, so that Heraclitus begins from a

preconception common to all men, as to us also, and perhaps to

the other schools of philosophy as well.[1] As the statement

concerning the appearance of contradictory predicates in regard

to the same thing is not an exclusively sceptical one, then

Scepticism is no more a path to the philosophy of Heraclitus

than to other schools of philosophy, or to life, as all use

common subject matter. "But we are afraid that the Sceptical

School not only does not help towards the knowledge of the

philosophy of Heraclitus, but even hinders that result. Since

the Sceptic accuses Heraclitus of having rashly dogmatised,

presenting on the one hand the doctrine of 'conflagration' and

on the other that 'contradictory predicates are in reality

applicable to the same thing.'"[2] "It is absurd, then, to say

that this conflicting school is a path to the sect with which it

conflicts. It is therefore absurd to say that the Sceptical

School is a path to the philosophy of Heraclitus."[3]

[1] _Hyp._ I. 211.

[2] _Hyp._ I. 212.

[3] _Hyp._ I. 212.

This is not the only place in the writings of Sextus which

states that Aenesidemus at some time of his life was an advocate

of the doctrines of Heraclitus. In no instance, however, where

Sextus refers to this remarkable fact, does he offer any

explanation of it, or express any bitterness against

Aenesidemus, whom he always speaks of with respect as a leader

of the Sceptical School. We are thus furnished with one of the

most difficult problems of ancient Scepticism, the problem of

reconciling the apparent advocacy of Aenesidemus of the

teachings of Heraclitus with his position in the Sceptical

School.

A comparison with each other of the references made by Sextus

and other writers to the teachings of Aenesidemus, and a

consideration of the result, gives us two pictures of

Aenesidemus which conflict most decidedly with each other. We

have on the one hand, the man who was the first to give

Pyrrhonism a position as an influential school, and the first to

collect and present to the world the results of preceding

Sceptical thought. He was the compiler of the ten Tropes of

[Greek: epochê], and perhaps in part their author, and the

author of the eight Tropes against aetiology.[1] He develops his

Scepticism from the standpoint that neither the senses nor the

intellect can give us any certain knowledge of reality.[2] He

denied the possibility of studying phenomena as signs of the

unknown.[3] He denied all possibility of truth, and the reality

of motion, origin and decay. There was according to his teaching

no pleasure or happiness, and no wisdom or supreme good. He

denied the possibility of finding out the nature of things, or

of proving the existence of the gods, and finally he declared

that no ethical aim is possible.

[1] _Hyp._ I. 180.

[2] Photius 170, B. 12.

[3] _Adv. Math._ VIII. 40.

The picture on the other hand, presented to us by Sextus and

Tertullian, is that of a man with a system of beliefs and

dogmas, which lead, he says, to the philosophy of Heraclitus. In

strange contradiction to his assertion of the impossibility of

all knowledge, he advocates a theory that the original substance

is air,[1] which is most certainly a dogma, although indeed a

deviation from the teachings of Heraclitus, of which Sextus

seemed unconscious, as he says, [Greek: to te on kata ton

Hêrakleiton aêr estin, hôs physin ho Ainêsidêmos]. Aenesidemus

dogmatised also regarding number and time and unity of the

original world-stuff.[2] He seems to have dogmatised further

about motion,[3] and about the soul.[4]

If Sextus' language is taken according to its apparent meaning,

we find ourselves here in the presence of a system of beliefs

which would be naturally held by a follower of the

Stoic-Heraclitan physics,[5] and absolutely inexplicable from

the standpoint of a man who advocated so radical a Scepticism as

Aenesidemus. Sextus in the passage that we first quoted,[6]

expresses great indignation against the idea that Scepticism

could form the path to the philosophy of Heraclitus, but he does

not express surprise or indignation against Aenesidemus

personally, or offer any explanation of the apparent

contradiction; and while his writings abound in references to

him as a respected leader of the Sceptical School, he sometimes

seems to include him with the Dogmatics, mentioning him with the

[Greek: dogmatikôn philosophôn].[7] In fact, the task of

presenting any consistent history of the development of thought

through which Aenesidemus passed is such a puzzling one, that

Brochard brilliantly remarks that possibly the best attitude to

take towards it would be to follow the advice of Aenesidemus

himself, and suspend one's judgment altogether regarding it. Is

it possible to suppose that so sharp and subtle a thinker as

Aenesidemus held at the same time such opposing opinions?

[5] Compare Zeller _Op. cit._ III. p. 33.

[6] _Hyp._ I. 210-212.

[7] _Adv. Math._ VIII. 8; X. 215.

The conjecture that he was first a Heraclitan Stoic, and later a

Sceptic, which might be possible, does not offer any explanation

of Sextus' statement, that he regarded Scepticism as a path to

the philosophy of Heraclitus. Nor would it be logical to think

that after establishing the Sceptical School in renewed

influence and power, he reverted to the Heraclitan theories as

they were modified by the Stoics. These same theories were the

cause of his separation from the Academy, for his chief

accusation against the Academy was that it was adopting the

dogmatism of the Stoics.[1] The matter is complicated by the

fact that Tertullian also attributes to Aenesidemus

anthropological and physical teachings that agree with the

Stoical Heraclitan doctrines. It is not strange that in view of

these contradictory assertions in regard to the same man, some

have suggested the possibility that they referred to two

different men of the same name, a supposition, however, that no

one has been able to authoritatively vindicate.

Let us consider briefly some of the explanations which have been

attempted of the apparent heresy of Aenesidemus towards the

Sceptical School. We will begin with the most ingenious, that of

Pappenheim.[2]

Pappenheim claims that Sextus was not referring to Aenesidemus

himself in these statements which he joins with his name. In the

most important of these, the one quoted from the

_Hypotyposes_,[3] which represents Aenesidemus as claiming that

Scepticism is the path to the philosophy of Heraclitus, the

expression used is [Greek: hoi peri ton Ainêsidêmon], and in

many of the other places where Sextus refers to the dogmatic

statements of Aenesidemus, the expression is either [Greek: hoi

peri ton Ainêsidêmon], or [Greek: Ainêsidêmos kath'

Hêrakleiton], while when Sextus quotes Aenesidemus to sustain

Scepticism, he uses his name alone.

[1] Compare Zeller _Op. cit._ III. p. 16.

[2] _Die angebliche Heraclitismus des Skeptikers

Ainesidemos_, Berlin 1889.

[3] _Hyp._ I. 210-212.

Pappenheim thinks that Sextus' conflict was not with the dead

Aenesidemus, who had lived two centuries before him, but with

his own contemporaries. He also seeks to prove that Sextus could

not have gained his knowledge of these sayings of Aenesidemus

from any of Aenesidemus' own writings, as neither by the

ancients, nor by later writers, was any book spoken of which

could well have contained them. Neither Aristocles nor Diogenes

mentions any such book.

Pappenheim also makes much of the argument that Sextus in no

instance seems conscious of inconsistency on the part of

Aenesidemus, even when most earnestly combating his alleged

teachings, but in referring to him personally he always speaks

of him with great respect.

Pappenheim suggests, accordingly, that the polemic of Sextus was

against contemporaries, those who accepted the philosophy of

Heraclitus in consequence of, or in some connection with, the

teachings of Aenesidemus. He entirely ignores the fact that

there is no trace of any such school or sect in history, calling

themselves followers of "Aenesidemus according to Heraclitus,"

but still thinks it possible that such a movement existed in

Alexandria at the time of Sextus, where so many different sects

were found. Sextus use Aenesidemus' name in four different

ways:--alone, [Greek: hoi peri ton Ainesidêmon], [Greek:

Ainêsidêmos kath' Hêrakleiton], and in one instance [Greek: hoi

peri ton Ainêsidêmon kath' Hêrakleiton].[1]

[1] _Adv. Math._ VIII. 8.

Pappenheim advances the theory that some of these contemporaries

against whom Sextus directed his arguments had written a book

entitled [Greek: Ainêsidêmos kath' Hêrakleiton], to prove the

harmony between Aenesidemus and Heraclitus, and that it was from

this book that Sextus quoted the dogmatic statements which he

introduced with that formula. He claims, further, that the

passage quoted from _Hypotyposes I._ even, is directed

against contemporaries, who founded their system of proofs of

the harmony between Aenesidemus and Heraclitus on the connection

of the celebrated formula which was such a favourite with the

Sceptics: "Contrary predicates appear to apply to the same

thing," with the apparent deduction from this, that "Contrary

predicates in reality apply to the same thing." Sextus wishes,

according to Pappenheim, to prove to these contemporaries that

they had misunderstood Aenesidemus, and Sextus does not report

Aenesidemus to be a Dogmatic, nor to have taught the doctrines

of Heraclitus; neither has he misunderstood Aenesidemus, nor

consequently misrepresented him; but on the contrary, these

dogmatic quotations have nothing to do with Aenesidemus, but

refer altogether to contemporaries who pretended to be Sceptics

while they accepted the teachings of Heraclitus. Sextus

naturally warmly combats this tendency, as he wishes to preserve

Pyrrhonism pure.

Brochard advocates a change of opinion on the part of

Aenesidemus as an explanation of the difficulty in question.[1]

He starts from the supposition, the reasonableness of which we

shall consider later, that Aenesidemus had passed through one

change of opinion already when he severed his connection with

the New Academy; and to the two phases of his life, which such a

change has already made us familiar with, he adds a third.

Aenesidemus would not be the first who has accepted different

beliefs at different periods of his life, and Brochard claims

that such a development in the opinions of Aenesidemus is

logical. He does not accuse Aenesidemus of having, as might seem

from the perusal of Sextus, suddenly changed his basis, but

rather of having gradually come to accept much in the teachings

of Heraclitus. Aenesidemus modifies his Scepticism only to the

extent of pretending to know something of absolute reality. The

Sceptic says, "Contradictory predicates are apparently

applicable to the same thing," and Aenesidemus accepts the

Heraclitan result--"Contradictory predicates are in reality

applicable to the same thing." From Sextus' report, Aenesidemus

would seem to have renounced his position as a Sceptic in saying

that Scepticism is the path to the philosophy of Heraclitus. He

does not, however, renounce Scepticism, but he finds it

incomplete. In deliberating concerning the appearance of

contradictory predicates in regard to the same object, he would

naturally ask, "Whence come these contradictory appearances?"

After having doubted all things, he wished to know wherefore he

doubts. The system of Heraclitus offers a solution, and he

accepts it. Contradictory predicates produce equilibrium in the

soul because they are an expression of reality.

[1] Brochard _Op. cit._ 272.

As a Sceptic he claims that knowledge is impossible, and he does

not find that the statement of Heraclitus disproves this, but

rather that it supports his theory. He had denied the existence

of science. He still does so, but now he knows why he denies it.

Brochard asks why it is any more impossible that Aenesidemus

should have been a follower of Heraclitus than that Protagoras

was so, as Protagoras was after all a Sceptic. In conclusion,

Brochard claims that the dogmatic theories attributed to

Aenesidemus relate to the doctrine of the truth of contradictory

predicates, which seemed to him a logical explanation of the

foundation theories of Scepticism. It is right to call him a

Sceptic, for he was so, and that sincerely; and he deserves his

rank as one of the chiefs of the Sceptical School.

Coming now to the opinion of Zeller,[1] we find that he

advocates a misconception of Aenesidemus on the part of Sextus.

The whole difficulty is removed, Zeller thinks, by the simple

fact that Sextus had not understood Aenesidemus; and as

Tertullian and Sextus agree in this misconception of the views

of Aenesidemus, they must have been misled by consulting a

common author in regard to Aenesidemus, who confused what

Aenesidemus said of Heraclitus with his own opinion. Zeller

maintains that the expression so often repeated by

Sextus--[Greek: Ainêsidêmos kath' Hêrakleiton]--shows that some

one of Aenesidemus' books contained a report of Heraclitus'

doctrines, as Aenesidemus was in the habit of quoting as many

authorities as possible to sustain his Scepticism. To justify

his quotations from Heraclitus, he had possibly given a short

abstract of Heraclitus' teachings; and the misconception

advocated by Zeller and found both in Tertullian and Sextus,

refers rather to the spirit than to the words quoted from

Aenesidemus, and is a misconception due to some earlier author,

who had given a false impression of the meaning of Aenesidemus

in quoting what Aenesidemus wrote about Heraclitus. That is to

say, Heraclitus was classed by Aenesidemus only among those who

prepared the way for Scepticism, just as Diogenes[2] mentions

many philosophers in that way; and that Soranus[3] and Sextus

both had the same misunderstanding can only be explained by a

mistake on the part of the authority whom they consulted.

Geschichte der Griechischen Phil._ p. 263.

[2] Diog. Laert. IX. 11, 71-74.

[3] Tertullian.

This explanation, however, makes Sextus a very stupid man.

Aenesidemus' books were well known, and Sextus would most

certainly take the trouble to read them. His reputation as an

historian would not sustain such an accusation, as Diogenes

calls his books [Greek: ta deka tôn skeptikôn kai alla

kallista].[1] Furthermore, that Sextus used Aenesidemus' own

books we know from the direct quotation from them in regard to

Plato,[2] which he combines with the ideas of Menodotus[3] and

his own.

[1] Diog. IX. 12, 116.

[2] _Hyp._ I. 222.

[3] Following the Greek of Bekker.

Sextus' references to Aenesidemus in connection with Heraclitus

are very numerous, and it is absurd to suppose that he would

have trusted entirely to some one who reported him for authority

on such a subject. Even were it possible that Sextus did not

refer directly to the works of Aenesidemus, which we do not

admit, even then, there had been many writers in the Sceptical

School since the time of Aenesidemus, and they certainly could

not all have misrepresented him. We must remember that Sextus

was at the head of the School, and had access to all of its

literature. His honor would not allow of such a mistake, and if

he had indeed made it, his contemporaries must surely have

discovered it before Diogenes characterised his books as [Greek:

kallista]. Whatever may be said against the accuracy of Sextus

as a general historian of philosophy, especially in regard to

the older schools, he cannot certainly be accused of ignorance

respecting the school of which he was at that time the head.

The opinion of Ritter on this subject is that Aenesidemus must

have been a Dogmatic.[1] Saisset contends[2] that Aenesidemus

really passed from the philosophy of Heraclitus to that of

Pyrrho, and made the statement that Scepticism is the path to

the philosophy of Heraclitus to defend his change of view,

although in his case the change had been just the opposite to

the one he defends. Saisset propounds as a law in the history of

philosophy a fact which he claims to be true, that Scepticism

always follows sensationalism, for which he gives two examples,

Pyrrho, who was first a disciple of Democritus, and Hume, who

was a disciple of Locke It is not necessary to discuss the

absurdity of such a law, which someone has well remarked would

involve an _a priori_ construction of history. There is no

apparent reason for Saisset's conjecture in regard to

Aenesidemus, for it is exactly the opposite of what Sextus has

reported. Strange to say, Saisset himself remarks in another

place that we owe religious respect to any text, and that it

should be the first law of criticism to render this.[3] Such

respect to the text of Sextus, as he himself advocates, puts

Saisset's explanation of the subject under discussion out of the

question.

Hirzel and Natorp do not find such a marked contradiction in the

two views presented of the theories of Aenesidemus, nor do they

think that Sextus has misrepresented them. They rather maintain,

that in declaring the coexistence of contradictory predicates

regarding the same object, Aenesidemus does not cease to be a

Sceptic, for he did not believe that the predicates are

applicable in a dogmatic sense of the word, but are only

applicable in appearance, that is, applicable to phenomena. The

Heraclitism of Aenesidemus would be then only in appearance, as

he understood the statement, that "Contradictory predicates are

in reality applicable to the same thing," only in the phenomenal

sense.[1] Hirzel says in addition, that contradictory predicates

are in reality applicable to those phenomena which are the same

for all, and consequently true, for Aenesidemus considered those

phenomena true that are the same for all.[2] As Protagoras, the

disciple of Heraclitus, declared the relative character of

sensations, that things exist only for us, and that their nature

depends on our perception of them; so, in the phenomenal sense,

Aenesidemus accepts the apparent fact that contradictory

predicates in reality apply to the same thing.

[1] Natorp _Op. cit._ 115, 122.

[2] _Adv. Math._ VIII. 8; Hirzel _Op. cit._ p. 95.

This explanation entirely overlooks the fact that we have to do

with the word [Greek: huparchein], in the statement that

contradictory predicates in reality apply to the same thing;

while in the passage quoted where Aenesidemus declares common

phenomena to be true ones, we have the word [Greek: alêthê], so

that this explanation of the difficulty would advocate a very

strange use of the word [Greek: huparchein].

All of these different views of the possible solution of this

perplexing problem are worthy of respect, as the opinion of men

who have given much thought to this and other closely Belated

subjects. While we may not altogether agree with any one of

them, they nevertheless furnish many suggestions, which are very

valuable in helping to construct a theory on the subject that

shall satisfactorily explain the difficulties, and present a

consistent view of the attitude of Aenesidemus.

First, in regard to the Greek expression [Greek: hoi peri] in

connection with proper names, upon which Pappenheim bases so

much of his argument. All Greek scholars would agree that the

expression does not apply usually only to the disciples of any

teacher, but [Greek: hoi peri ton Ainêsidêmon], for instance,

includes Aenesidemus with his followers, and is literally

translated, "Aenesidemus and his followers." It is noticeable,

however, in the writings of Sextus that he uses the expression

[Greek: hoi peri] often for the name of the founder of a school

alone, as Pappenheim himself admits.[1] We find examples of this

in the mention of Plato and Democritus and Arcesilaus, as

[Greek: hoi peri ton Platôna kai Dêmokriton][2] and [Greek: hoi

peri ton Arkesilaon],[3] and accordingly we have no right to

infer that his use of the name Aenesidemus in this way has an

exceptional significance. It may mean Aenesidemus alone, or it

may signify Aenesidemus in connection with his followers.

In reply to Zeller's position, that Sextus and Tertullian have

misunderstood Aenesidemus, and quote from some common author who

misrepresents him, we would admit that such a misunderstanding

might be possible where Sextus gives long explanations of

Heraclitus' teachings, beginning with quoting Aenesidemus, and

continuing in such a way that it is not always possible to

distinguish just the part that is attributed to Aenesidemus; but

such a misunderstanding certainly cannot be asserted in regard

to the direct statement that Aenesidemus regarded Scepticism as

the path to the philosophy of Heraclitus, for the reasons

previously given. Neither would we agree with Brochard, whose

solution of the difficulty is on the whole the most logical,

_i.e._, that Aenesidemus had necessarily already passed through

two phases of philosophical belief. It is possible to admit a

gradual evolution of thought in Aenesidemus without supposing in

either case a change of basis. His withdrawal from the Academy

is an argument against, rather than in favor of a change on his

part, and was caused by the well-known change in the attitude of

the Academy.

Many of the teachings of the Sceptical School were taken

directly from the Academy, belonging to those doctrines

advocated in the Academy before the eclectic dogmatic tendency

introduced by Antiochus. In fact, Sextus himself claims a close

relation between the Middle Academy and Pyrrhonism.[1]

Aenesidemus, although he was a Sceptic, belonged to the Academy,

and on leaving it became, as it were, a pioneer in Pyrrhonism,

and cannot be judged in the same way as we should judge a

Sceptic of Sextus' time.

It seems a self-evident fact that during the two centuries which

elapsed between the time of Aenesidemus and Sextus, the

standpoint of judgment in the Sceptical School had greatly

changed. An example illustrating this change we find in a

comparison of the presentation of Scepticism by Diogenes with

that of Sextus. The author Whom Diogenes follows, probably one

of the Sceptical writers, considers Xenophanes, Zeno, and

Democritus, Sceptics, and also Plato,[2] while Sextus, in regard

to all of these men, opposes the idea that they were

Sceptics.[3] Diogenes also calls Heraclitus a Sceptic, and even

Homer,[4] and quotes sceptical sayings from the Seven Wise

Men;[5] he includes in the list of Sceptics, Archilochus,

Euripides, Empedocles, and Hippocrates,[6] and, furthermore,

says that Theodosius, probably one of the younger Sceptics,

objected to the name 'Pyrrhonean' on the ground that Pyrrho was

not the first Sceptic.[7]

We have given the testimony from many sources to the effect that

before the time of Sextus the Empirical School of Medicine was

considered identical with Scepticism, although not so by Sextus

himself. From all of these things we may infer a narrowing of

the limits of Pyrrhonism in the time of Sextus.

Let us accept with Brochard the development of thought seen in

Aenesidemus from the beginning to the end of his career, without

agreeing with him that Aenesidemus ever consciously changed his

basis. He was a Sceptic in the Academy. He left the Academy on

that account, and he remained a Sceptic to the end, in so far as

a man can be a Sceptic, and take the positive stand that

Aenesidemus did.

Two things might account for his apparent dogmatism--

(i) The eclectic spirit of his time.

(ii) The psychological effect upon himself of this

careful systemisation of the Sceptical teachings.

Let us consider the first of these causes. Aenesidemus, although

not the first of the later Sceptics, was apparently the first to

separate himself from the Academy. He was the founder of a new

movement, the attempt to revive the older Scepticism as taught

by Pyrrho and Timon, and separate it from the dogmatic teachings

of the Stoics which were so greatly affecting the Scepticism of

the New Academy. It was the spirit of his time to seek to

sustain all philosophical teaching by the authority of as many

as possible of the older philosophers, and he could hardly

escape the tendency which his training in the Academy had

unconsciously given him. Therefore we find him trying to prove

that the philosophy of Heraclitus follows from Scepticism. It is

not necessary either to explain the matter, as both Hirzel and

Natorp so ingeniously attempt to do, by claiming that the truth

of contradictory predicates which Aenesidemus accepted from

Heraclitus referred only to phenomena. The history of philosophy

gives us abundant proof of the impossibility of absolute

Scepticism, and Aenesidemus furnishes us with one example of

many of this impossibility, and of the dogmatism that must exist

in connection with all thought. In the case of Aenesidemus, who

evidently gave the best efforts of his life to establish the

Sceptical School, the dogmatism was probably unconscious. That

he remained to the end a Sceptic is shown by the fact that he

was known as such to posterity. Nowhere do we find a change of

basis referred to in regard to him, and Sextus, in refuting the

mistakes which he attributes to Aenesidemus, does it, as it

were, to point out something of which Aenesidemus had been

unconscious.

Let us consider here the second cause of Aenesidemus' Dogmatism,

the psychological effect upon himself of formulating Sceptical

beliefs. The work that he did for the Sceptical School was a

positive one. It occupied years of his life, and stamped itself

upon his mental development. In formulating Scepticism, and in

advocating it against the many enemies of the School, and amidst

all the excitement of the disruption from the Academy, and of

establishing a new School, it was inevitable that his mind

should take a dogmatic tendency. He remained a Sceptic as he had

always been, but must have grown dogmatic in his attitude

towards the Sceptical formulae, and was thus able to adopt some

of the teachings of Heraclitus, unconscious of their

inconsistency.

Where should we find a modern writer who is consistent in all

his statements? Could we read the works of Aenesidemus, we might

better understand the connection between the apparently

contradictory ideas in his teaching, but the inconsistencies in

statement would probably remain. It is necessary to remember the

position of Aenesidemus in breaking away from the Academy and in

founding a new school, the full significance of which he could

not foresee. There must necessarily be some crudeness in pioneer

work, and some failure to see the bearing of all its parts, and

a compiler like Sextus could point out the inconsistencies which

the two centuries since the time of Aenesidemus had made plain.

Aenesidemus was too positive a character to admit of absolute

Sceptical consistency. He was nevertheless the greatest thinker

the Sceptical School had known since the age of Pyrrho, its

founder. In claiming a union between Pyrrhonism and the

philosophy of Heraclitus, he recognised also the pre-Socratic

tendency of the Sceptical School. The name of Socrates was all

powerful in the Academy, but Aenesidemus comprehended the fact

that the true spirit of Pyrrhonism was of earlier origin than

the Academic Scepsis.

CHAPTER V.

_Critical Examination of Pyrrhonism_.

The distinct philosophical movement of which Pyrrho was the

author bore his name for five centuries after his death. It had

an acknowledged existence as a philosophical tendency, if indeed

not a sect, for a great part of that time. Yet, when we

carefully analyse the relation of Pyrrhonism, as presented to us

by Sextus, to the teachings of Pyrrho himself, in so far as they

can be known, we find many things in Pyrrhonism for which Pyrrho

was not responsible.

The foundation elements of the movement, the spirit of Empirical

doubt that lay underneath and caused its development in certain

directions rather than others, are due to Pyrrho. The methods of

the school, however, were very foreign to anything found in the

life or teachings of Pyrrho. Pyrrho was eminently a moralist. He

was also to a great degree an ascetic, and he lived his

philosophy, giving it thus a positive side wanting in the

Pyrrhonism presented to us by Sextus. Timon represents him as

desiring to escape from the tedious philosophical discussions of

his time--

[Greek:

ô geron ô Purrhôn, pôs ê pothen ekdusin heures

latreiês doxôn te kenophrosunês te sophistôn;]

and again he speaks of his modest and tranquil life--

[Greek:

touto moi, ô Purrhôn, himeiretai êtor akousai

pôs pot' anêr et' ageis panta meth' hêsuchiês

mounos d'anthrôpoisi theou tropon hêgemoneueis

..... phêista meth' hêsuchiês

aiei aphrontistôs kai akinêtôs kata tauta

mê prosech' indalmois hêdulogou sophiês.][1]

Pyrrho wished more than anything else to live in peace, and his

dislike of the Sophists[2] may well have made him try to avoid

dialectic; while, on the contrary, in the Pyrrhonean School of

later times discussion was one of the principal methods of

contest, at least after the time of Agrippa. Pyrrhonism seems to

have been originally a theory of life, like the philosophy of

Socrates, to whom Pyrrho is often compared,[3] and Pyrrho, like

Socrates, lived his philosophy. Our knowledge of Pyrrho is

gained from Aristocles, Sextus Empiricus, and Diogenes, and from

the Academic traditions given by Cicero. Diogenes gives us

details of his life which he attributes to Antigonus of

Carystius, who lived about the time of Pyrrho.[4] Pyrrho was a

disciple and admirer of Democritus,[5] some of whose teachings

bore a lasting influence over the subsequent development of

Pyrrhonism. He accompanied Alexander the Great to India, where

he remained as a member of his suite for some time, and the

philosophical ideas of India were not without influence on his

teachings. Oriental philosophy was not unknown in Greece long

before the time of Pyrrho, but his personal contact with the

Magi and the Gymnosophists of the far East, apparently impressed

upon his mind teachings for which he was not unprepared by his

previous study and natural disposition. In his indifference to

worldly goods we find a strong trace of the Buddhistic teaching

regarding the vanity of human life. He showed also a similar

hopelessness in regard to the possibility of finding a

satisfactory philosophy, or absolute truth. He evidently

returned from India with the conviction that truth was not to be

attained.[6]

After the death of Alexander and Pyrrho's return to Greece, he

lived quietly with his sister at Elis, and Diogenes says that he

was consistent in his life, asserting and denying nothing, but

in everything withholding his opinion, as nothing in itself is

good or shameful, just or unjust.[1] He was not a victim of

false pride, but sold animals in the market place, and, if

necessary, washed the utensils himself.[2] He lived in equality

of spirit, and practised his teachings with serenity. If one

went out while he was talking he paid no attention, but went

calmly on with his remarks.[3] He liked to live alone, and to

travel alone, and on one occasion, being knocked about in a

vessel by a storm at sea, he did not lose his imperturbability,

but pointed to a swine calmly eating on board, and said that the

wise man should have as much calmness of soul as that. He

endured difficult surgical operations with indifference,[4] and

when his friend Anaxarchus was once unfortunate enough to fall

into a morass, he went calmly by without stopping to help him,

for which consistency of conduct Anaxarchus afterwards praised

him. There are two instances given by Diogenes when he lost

control of himself; once in getting angry with his sister, and

once in trying to save himself when chased by a dog. When

accused of inconsistency, he said it was difficult to entirely

give up one's humanity.[5] He was greatly venerated by the

people among whom he lived, who made him high priest, and on his

account exempted all philosophers from taxation,[6] and after

his death erected a statue to his memory. These facts testify to

his moral character, and also to fulfil the functions of high

priest a certain amount of dogmatism must have been necessary.

According to Diogenes, "We cannot know," said Pyrrho, "what

things are in themselves, either by sensation or by judgment,

and, as we cannot distinguish the true from the false, therefore

we should live impassively, and without an opinion." The term

[Greek: epochê], so characteristic of Pyrrhonism, goes back,

according to Diogenes, to the time of Pyrrho.[1] Nothing is, in

itself, one thing more than another, but all experience is

related to phenomena, and no knowledge is possible through the

senses.[2] Pyrrho's aim was [Greek: ataraxia] and his life

furnished a marked example of the spirit of indifference, for

which the expression [Greek: apatheia] is better suited than the

later one, [Greek: ataraxia]. The description of his life with

his sister confirms this, where the term [Greek: adiaphoria] is

used to describe his conduct.[3] He founded his Scepticism on

the equivalence of opposing arguments.[4]

The picture given of Pyrrho by Cicero is entirely different from

that of Diogenes, and contrasts decidedly with it.[1] Cicero

knows Pyrrho as a severe moralist, not as a Sceptic. Both

authors attribute to Pyrrho the doctrine of indifference and

apathy, but, according to Cicero, Pyrrho taught of virtue,

honesty, and the _summum bonum_, while Diogenes plainly tells us

that he considered nothing as good in itself, "and of all things

nothing as true."[2] Cicero does not once allude to Pyrrhonean

doubt. We see on the one hand, in Cicero's idea of Pyrrho, the

influence of the Academy, perhaps even of Antiochus himself,[3]

which probably colored the representations given of Pyrrho; but,

on the other hand, there is much in Diogenes' account of

Pyrrho's life and teachings, and in the writings of Timon, which

shows us the positive side of Pyrrho. Pyrrho, in denying the

possibility of all knowledge, made that rather a motive for

indifference in the relations of life, than the foundation

thought of a philosophical system. His teaching has a decided

ethical side, showing in that respect the strong influence of

Democritus over him, who, like Pyrrho, made happiness to consist

in a state of feeling.[4] The one motive of all of Pyrrho's

teaching is a positive one, the desire for happiness.

[2] Diog. IX. 11, 61.

[3] Compare Natorp _Op. cit._ p. 71.

[4] Zeller _Grundriss der Griechischen Phil._ p. 70.

The essence of Pyrrhonism as given by Timon is as follows:[1]

Man desires to be happy. To realise his desire he must consider

three things:

(i) What is the nature of things?

(ii) How should man conduct himself in relation to

them?

(iii) What is the result to him of this relation?

The nature of things is unknown. Our relation to them must be

one of suspension of judgment, without activity, desire, or

belief,--that is, an entirely negative relation. The result is

that state of having no opinion, called [Greek: epochê], which

is followed in turn by [Greek: ataraxia].

[1] Aristocles _ap. Eusebium Praep. Ev._ XIV. 18.

[1]The problem of philosophy is here proposed very nearly in the

terms of Kant, but not with the positive motive, like that of

the great philosopher of Germany, of evolving a system to

present the truth. Yet the importance of these questions shows

the originality of Pyrrho. The earnestness of Pyrrho is further

shown by an example given by Diogenes. Once on being found

talking to himself alone, he said, when asked the reason, that

he was meditating how to become a good man ([Greek:

chrêstos]),[2] thus showing an entirely different spirit from

anything found in Sextus' books. The explanation of his life and

teachings is to be found largely in his own disposition. Such an

attitude of indifference must belong to a placid nature, and

cannot be entirely the result of a philosophical system, and,

while it can be aimed at, it can never be perfectly imitated.

One of his disciples recognised this, and said that it was

necessary to have the disposition of Pyrrho in order to hold his

doctrines.[3] Diogenes tells us that he was the first to advance

any formulae of Scepticism,[4] but they must have been very

elementary, as Pyrrho himself wrote nothing. We find no trace of

formulated Tropes in Pyrrho's teachings, yet it is probable that

he indicated some of the contradictions in sensation, and

possibly the Tropes in some rudimentary form. Of the large

number of sceptical formulae, or [Greek: phônai], the three

which seem to have the oldest connection with Scepticism are the

[Greek: antilogia], the [Greek: ouden horizô], and the [Greek:

ou mallon].[5] We know from Diogenes that Protagoras is the

authority for saying that in regard to everything there are two

opposing arguments.[6] The saying "to determine nothing" is

quoted from Timon's _Python_ by Diogenes,[7] and the other two

mentioned are also attributed to him by Aristocles.[8] We have

also in the [Greek: ou mallon] a direct connection with

Democritus, although the difference in the meaning which he

attributed to it is shown by Sextus.[9] So while the expression

is the same, the explanation of it given by Pyrrho must have

been different. It would seem probable that Pyrrho used all of

these three sayings, from the account of Diogenes, and that even

then they gave rise to the accusation of the Dogmatics, that

simply by possessing such sayings the Sceptics dogmatised,[10]

for the refutation of this used by Sextus occurs in the old

account of the sayings, namely, that these formulae include also

themselves in the meaning, as a cathartic removes itself

together with other harmful objects.[11]

In comparing the later Pyrrhonism with the teachings of Pyrrho,

we would sharply contrast the moral attitude of the two. With

Pyrrho equilibrium of soul was a means to be applied to his

positive theory of life; with the later Pyrrhoneans it was the

end to be attained. We would attribute, however, the empirical

tendency shown during the whole history of Pyrrhonism to Pyrrho

as its originator. He was an empirical philosopher, and the

result of his influence in this respect, as seen in the

subsequent development of the school, stands in marked contrast

to the dialectic spirit of the Academic Scepsis. The empiricism

of the school is shown in its scientific lore, in the fact that

so many of the Sceptics were physicians, and in the character of

the ten Tropes of [Greek: epochê]. We may safely affirm that

the foundation principles of Pyrrhonism are due to Pyrrho, and

the originality which gave the school its power. The elaborated

arguments, however, and the details of its formulae belong to

later times.

Coming now to the relation of Pyrrhonism to the Academy, the

connection between the two is difficult to exactly determine,

between the time of Pyrrho and that of Aenesidemus. Scepticism

in the Academy was, however, never absolutely identical with

Pyrrhonism, although at certain periods of the history of the

Academy the difference was slight. We can trace throughout the

evolution of doubt, as shown to us in Pyrrhonism, and in

Academic Scepticism, the different results which followed the

difference in origin of the two movements, and these differences

followed according to general laws of development of thought.

Arcesilaus, who introduced doubt into the Academy, claimed to

return to the dialectic of Socrates, and suppressing the

lectures,[1] which were the method of teaching in the later

schools of philosophy, introduced discussions instead, as being

more decidedly a Socratic method. Although, according to Sextus,

he was the one leader of the Academy whose Scepticism most

nearly approached that of Pyrrhonism,[2] yet underneath his

whole teaching lay that dialectic principle so thoroughly in

opposition to the empiricism of Pyrrho. The belief of Socrates

and Plato in the existence of absolute truth never entirely lost

its influence over the Academy, but was like a hidden germ,

destined to reappear after Scepticism had passed away. It

finally led the Academy back to Dogmatism, and prepared the way

for the Eclecticism with which it disappeared from history.

[1] Compare Maccoll _Op. cit._ p. 36.

[2] _Hyp_. I. 232.

The history of Pyrrhonism and that of Academic Scepticism were

for a time contemporaneous. The immediate follower of Pyrrho,

Timon, called by Sextus the "prophet of Pyrrho,"[1] was a

contemporary of Arcesilaus. That he did not consider the

Scepticism of the Academy identical with Pyrrhonism is proved

from the fact that he did not himself join the Academy, but was,

on the contrary, far from doing so. That he regarded Arcesilaus

as a Dogmatic is evident from his writings.[2] One day, on

seeing the chief of the Academy approaching, he cried out, "What

are you doing here among us who are free?"[3] After the death of

Timon, the Pyrrhonean School had no representative till the time

of Ptolemy of Cyrene,[4] and Greek Scepticism was represented by

the Academy. That Pyrrho had a strong influence over Arcesilaus,

the founder of the Middle Academy, is evident[5]; but there was

also never a time when the Academy entirely broke away from all

the teachings of Plato, even in their deepest doubt.[6] It is

true that Arcesilaus removed, nominally as well as in spirit,

some of the dialogues of Plato from the Academy, but only those

that bore a dogmatic character, while those that presented a

more decided Socratic mode of questioning without reaching any

decided result, men regarded as authority for Scepticism.

Sextus does not deny that Arcesilaus was almost a Pyrrhonean,

but he claims that his Pyrrhonism was only apparent, and not

real, and was used as a cloak to hide his loyalty to the

teachings of Plato.[1] As Ariston said of him,[2] "Plato before,

Pyrrho behind, Diodorus in the middle." Sextus also

characterises the method of Arcesilaus as dialectic,[3] and we

know from Cicero that it was his pride to pretend to return to

the dialectic of Socrates.

It is interesting to note that Sextus, in his refutation of the

position that the Academy is the same as Pyrrhonism, takes up

the entire development of Academic thought from the time of

Plato till that of Antiochus, and does not limit the argument to

Scepticism under Arcesilaus. The claim made by some that the two

schools were the same, is stated by him,[4] and the word 'some'

probably refers to members of both schools at different periods

of their history. Sextus recognises three Academies, although he

remarks that some make even a further division, calling that of

Philo and Charmides, the fourth, and that of Antiochus and his

followers, the fifth.

That many in the Academy, and even outside of it, regarded Plato

as a Sceptic, and an authority for subsequent Scepticism, we

find both from Sextus and Diogenes.[1] As Lewes justly remarks,

one could well find authority for Scepticism in the works of

Plato, as indeed the Academicians did, but not when the sum

total of his teachings was considered. The spirit of Plato's

teachings was dogmatic, as Sextus most decidedly recognises, and

as Aenesidemus and Menodotus[2] recognised before him.[3] Sextus

himself shows us that Plato's idealism and ethical teachings can

have nothing in common with Scepticism, for if he accepts the

desirability of the virtuous life, and the existence of

Providence, he dogmatises; and if he even regards them as

probable, he gives preference to one set of ideas over another,

and departs from the sceptical character. Sextus characterises

the sceptical side of Plato's writings as mental gymnastics,[4]

which do not authorise his being called a Sceptic, and affirms

that Plato is not a Sceptic, since he prefers some unknown

things to others in trustworthiness. The ethical difference

underlying the teachings of the Academy and Pyrrhonism, Sextus

was very quick to see, and although it is very probable that the

part of the _Hypotyposes_ which defines the difference between

the Academy and Pyrrhonism may be largely quoted from the

introduction to Aenesidemus' works, yet Sextus certainly gives

these statements the strong stamp of his approval. He condemns

the Academy because of the theory that good and evil exist, or

if this cannot be decidedly proved, yet that it is more probable

that what is called good exists than the contrary.[5]

The whole Academic teaching of probabilities contradicted the

standpoint of the Sceptics--that our ideas are equal as regards

trustworthiness and untrustworthiness,[1] for the Academicians

declared that some ideas are probable and some improbable, and

they make a difference even in those ideas that they call

probable.

Sextus claims that there are three fundamental grounds of

difference between Pyrrhonism and the Academy. The first is the

doctrine of probability which the Academicians accept in regard

to the superior trustworthiness of some ideas over others.[2]

The second is the different way in which the two schools follow

their teachers. The Pyrrhoneans follow without striving or

strong effort, or even strong inclination, as a child follows

his teacher, while the Academicians follow with sympathy and

assent, as Carneades and Clitomachus affirm.[3] The third

difference is in the aim, for the Academicians follow what is

probable in life. The Sceptics follow nothing, but live

according to laws, customs, and natural feelings

undogmatically.[4]

The difference between the later teaching of the Academy and

Pyrrhonism is evident, and Sextus treats of it briefly, as not

requiring discussion,[5] as Philo taught that the nature of

facts is incomprehensible, and Antiochus transferred the Stoa to

the Academy. It is therefore evident, from the comparison which

we have made, that we do not find in the Academy, with which

Scepticism after the death of Timon was so long united, the

exact continuance of Pyrrhonism. The philosophical enmity of the

two contemporaries, Timon and Arcesilaus, the Academician who

had most in common with Pyrrhonism, is an expression of the

fundamental incompatibility between the two schools.

During all the chequered history of the Academy the dormant

idealism was there, underlying the outward development. Although

during the time of Arcesilaus and Carneades the difference was

so slight as to seem a mere matter of form of expression, yet

the different foundations on which the two schools stood was

always recognisable. On the one hand there was the germ of

idealism which was destined to awake to a new life, and on the

other, the attempt at absolute negation which was to result in

the final extinction of Pyrrhonism. We find in both, it is true,

especially in the time of Arcesilaus, the aim of [Greek:

epochê].[1] Both placed great weight on [Greek: isostheneia], or

the equal value of opposing arguments.[2] The foundation of the

[Greek: epochê] was, however, different in the two cases.

Arcesilaus founded his on dialectic, while Pyrrho's was

empirical.

[1] _Hyp._ I. 232.

[2] Diog. IX. 73; _Hyp._ II. 130; III. 65.

The Pyrrhonean believed that ideas give us no knowledge of the

outer world; the Academic Sceptic believed that we cannot

distinguish between true and false ideas, so such knowledge is

impossible. The Pyrrhonean denied that truth could exist in

ideas because of their contradictory nature, and consequently

the existence of all truth, [Greek: mêden einai tê alêtheia epi

pantôn].[1] The Academic Sceptic granted that the truth was

possibly contained in ideas, but affirmed that it could never be

known to us. The Pyrrhoneans prided themselves on still being

seekers, for although ordinary ideas are too contradictory to

give knowledge of the outer world, they did not deny that such

knowledge might be possible, but simply suspended the judgment

regarding it. To the Pyrrhonean the result corresponded to the

method. All ideas thus far known revealed nothing of the truth,

therefore he still sought. The Academician tried logically to

prove that the truth is impossible to find. It is the relation

of the dialectician to the empiricist, and the two varieties of

Scepticism are explained by their difference in origin. In

Pyrrhonism there was no constructive element. In the Academic

Scepsis such an element was found throughout all its history in

the theory of Probability. Arcesilaus himself laid great stress

upon this doctrine, which Sextus carefully shows us[2] is

utterly inconsistent with Pyrrhonism. Arcesilaus plainly teaches

that, having suspended one's judgment in regard to matters of

knowledge, one should control his choices, his refusals, and his

actions by the probable.[3]

[1] Diog. IX. 11, 61.

[2] _Hyp._ I. 229.

[3] Compare Maccoll _Op. cit._ 39.

After Antiochus introduced Eclecticism into the Academy,

Pyrrhonism was the only representative of Greek Scepticism, and

it flourished for over two centuries after our era, and then

also disappeared, no more to exist as a regular philosophical

school.

Having considered at length the essence of Pyrrhonism as

presented by Sextus Empiricus, it now remains to briefly note

the characteristics that formed its strength and weakness, and

the causes of its final downfall. Herbart says that every

philosopher is a Sceptic in the beginning, but every Sceptic

remains always in the beginning. This remark may well be applied

to Pyrrhonism. We find in its teachings many fundamental

philosophical truths which might have formed the beginning of

great philosophical progress, but which were never developed to

any positive results. The teachings of Pyrrhonism were some of

them well fitted to prepare the way to idealism. The great idea

of the relativity of _Vorstellungen_ is made very prominent by

the ten Tropes of [Greek: epochê]. Aenesidemus, in his eight

Tropes against aetiology, shows the absurdity of the doctrine of

causality when upheld on materialistic grounds. That was to him

final, [Greek: epei ouk estai aition.] He could not divine that

although the result which he presented was logical, it only led

to a higher truth. It was reserved for the greatest of modern

philosophers to reveal to the world that causality is a

condition, and a necessary condition, of thought. When

Aenesidemus proved by his seventh Trope that causality is

subjective, he regarded it as fatal to the doctrine; yet this

conclusion was a marked step in advance in critical philosophy,

although Aenesidemus could not himself see it in all its

bearings. The great difference between Aenesidemus and Kant is

the difference between the materialist and the believer in

subjective reality. Both agreed in the unknown nature of the

_Ding an sich_, but this was to the Pyrrhonist the end of all

his philosophy; to Kant, however, the beginning.

Pyrrhonism has rendered, notwithstanding its points of fatal

weakness, marked service to the world in science, philosophy,

ethics, and religion. It quickened scientific thought by

emphasising empirical methods of investigation, and by

criticising all results founded without sufficient data upon

false hypotheses. If, instead of denying the possibility of all

science because of the want of a criterion of the truth of

phenomena, the Pyrrhonists had comprehended the possibility of a

science of phenomena, they might have led the world in

scientific progress.[1] Their service to philosophy lay in the

stimulus to thought that their frequent attacks on dogmatic

beliefs occasioned. Pyrrhonism brought together all the most

prominent theories of the old schools of philosophy to test

their weakness and expose their contradictions, and this very

process of criticism often demonstrated the power of the truth

which they contained.

Sextus Empiricus was often charged by the Church Fathers with

corrupting religious belief, and yet the greatest service which

Pyrrhonism has rendered the world was in religious and ethical

lines. This service did not, naturally, consist in destroying

belief in absolute truth, as the Sceptic professed to do, but in

preparing the way to find it. The bold attacks of Scepticism on

all truth led men to investigate ethical and religious

teachings, to examine the grounds of their belief, and to put in

practical use the right of reason and free discussion.

Scepticism was the antecedent of freedom of conscience and

rational criticism,[2] and the absolute right of scientific

thought. The Sceptics, however, reaped none of the benefits of

their own system. They remained, as it were, always on the

threshold of possible progress. With the keys to great

discoveries in their hands, the doors of philosophical and

scientific advancement were for ever closed to them by the

limitations of their own system. The inherent weakness of

Pyrrhonism lay in its psychological inconsistency and in its

negative character. I think that we may safely say that

Pyrrhonism was the most consistent system of Scepticism ever

offered to the world, and yet it proves most decidedly that

complete Scepticism is psychologically impossible. A man may

give up his belief in one set of ideas, and, if they are ideas

that are popularly accepted, he will be called a Sceptic, as was

the case with Hume. He must, however, replace these ideas by

others equally positive, and then he is no longer a Sceptic, but

a Dogmatic, for he believes in something.

[1] Compare Lewes _Op. cit._ p. 463.

[2] Compare Chaignet _Op. cit._ p. 460.

We have shown that the greatest thinkers of Pyrrhonism, Pyrrho,

Aenesidemus, and Agrippa, were not examples of absolute

Scepticism, and although Sextus Empiricus realised what

consistency demanded in this respect, and affirmed on almost

every page that he was asserting nothing, yet there is not a

paragraph of his books in which he does not, after all,

dogmatise on some subject. Complete Scepticism is contrary to

the fundamental laws of language, as all use of verbs involves

some affirmation. The Pyrrhonists realised this, and therefore

some of them wrote nothing, like Pyrrho, their leader, and

others advocated [Greek: aphasia][1] as one of the doctrines of

their system.

[1] _Hyp._ I. 192.

The very aim of Pyrrhonism was an inconsistent one. [Greek:

Ataraxia] was only another name for happiness, and in one

instance, even, is given as [Greek: hêdonê], and thus, in spite

of themselves, the Sceptics introduced a theory of happiness.

Pyrrho, like others of his time, sought the highest good, and

thought that he had found it in [Greek: ataraxia], the peace of

mind that appears in other systems of philosophy in other forms.

The difference of aim between the Pyrrhonists, Stoics, and

Epicureans was more apparent than real. To them all philosophy

was a path to lead to happiness. The method of Pyrrhonism was,

however, negative. Its strength consisted in its attacks on

Dogmatism, and not in any positive aim of its own, for its

positive side could not be recognised according to its own

doctrines. Therefore there was no real development in

Pyrrhonism, for a negative thought cannot be developed.

We find, accordingly, from the time of Pyrrho to Sextus, no

growth in breadth of philosophical outlook, only improvement in

methods. Philosophical activity can never have doubt as its aim,

as that would form, as we have shown, a psychological

contradiction. The true essence of Pyrrhonism was passivity, but

passivity can never lead to progress. Much of the polemical work

of Pyrrhonism prepared the way for scientific progress by

providing a vast store of scientific data, but progress was to

the Pyrrhonists impossible. They sounded their own scientific

death-knell by declaring the impossibility of science, and

putting an end to all theories.

The life of all scientific and philosophic progress is in the

attempt to find the hidden truth. To the Sceptic there was no

truth, and there could be no progress. As progress is a law in

the evolution of the human race, so Scepticism as a philosophy

could never be a permanent growth, any more than asceticism in

religion can be a lasting influence. Both of them are only

outgrowths. As the foundation principles of Scepticism were

opposed to anything like real growth, it was a system that could

never originate anything. Pyrrho taught from the beginning that

the Sceptic must live according to law and custom; not, however,

because one law or custom is better than another in itself, but

simply for the sake of peace. This basis of action was itself a

death-blow to all reform in social or political life. It was a

selfish, negative way of seeking what was, after all, a positive

thing, the [Greek: ataraxia] that the Sceptic desired. Life with

the Pyrrhonist was phenomenal, and not phenomenal simply in

regard to the outer world, but also subjectively, and no

absolute knowledge of the subjective life or of personal

existence was possible.

The cause of the downfall of Pyrrhonism lay in the fact that it

had nothing to offer to humanity in the place of what it had

destroyed. It made no appeal to human sympathies, and ignored

all the highest motives to human action. The especial

materialistic standpoint from which Pyrrhonism judged all that

pertains to knowledge and life shut out the ideal, and all

possibility of absolute truth. It was an expression of the

philosophic decadence of the age when it flourished, and

although it possessed some philosophic worth, yet it bore in

itself the causes of its decay.

CHAPTER I.

_The Principal Differences between Philosophers._

It is probable that those who seek after anything whatever, will 1

either find it as they continue the search, will deny that it

can be found and confess it to be out of reach, or will go on

seeking it. Some have said, accordingly, in regard to the things

sought in philosophy, that they have found the truth, while 2

others have declared it impossible to find, and still others

continue to seek it. Those who think that they have found it are

those who are especially called Dogmatics, as for example, the

Schools of Aristotle and Epicurus, the Stoics and some others.

Those who have declared it impossible to find are Clitomachus, 3

Carneades, with their respective followers, and other

Academicians. Those who still seek it are the Sceptics. It

appears therefore, reasonable to conclude that the three 4

principal kinds of philosophy are the Dogmatic, the Academic,

and the Sceptic. Others may suitably treat of the other Schools,

but as for the Sceptical School, we shall now give an outline of

it, remarking in advance that in respect to nothing that will be

said do we speak positively, that it must be absolutely so, but

we shall state each thing historically as it now appears to us.
