[Footnote 97: Ibid. b. 8-13.]

Again, among opinions generally received, there are some which the

public recognize as matters of more or less doubt and uncertainty;

others, on which they are firmly assured that every one who

contradicts them speaks falsely. When it is uncertain to which of

these two classes the question put is referable, the respondent will

be safer in answering neither affirmatively nor negatively, but

simply, "I go with the received opinions."[98] In cases where

opinions are divided, he may find opportunity for changing the terms,

and for substituting a metaphorical equivalent as what he concedes.

Such change of terms may pass without protest, in consequence of the

doubtful character of the matter; while it will embarrass the

questioner in constructing his refutation.[99] The respondent may

further embarrass him by anticipating questions that seem likely to

be put, and by objecting against them beforehand.[100]

[Footnote 98: Soph. El. **xvii. p. 176, b. 14-20.

Both the text and the meaning of this difficult clause are

differently given by various commentators. The text and construction

of Waitz appears to me the best, and I have followed him. I cannot

agree with Mr. Poste when he declares (notes, p. 143) [Greek:

a)popha/neis] to be the true reading, instead of [Greek:

a)popha/seis], which last is adopted both by Bekker and in the

edition of **Firmin Didot.]

[Footnote 99: Ibid. b. 20-25.]

[Footnote 100: Ibid. b. 26.]

When the questioner has obtained the premisses which he thinks

necessary, and has drawn from them a refutative syllogism, the

respondent must see whether he can properly solve that syllogism or

not.[101] A good and proper solution is, to point out on which

premiss the fallacy of the conclusion depends. First, he must examine

whether it is formally correct, or whether it has only a false

appearance of being so: if the last be the case, he must distinguish

in which of the premisses and in what way such false appearance has

arisen. If on the other hand the syllogism is formally correct, he

must look whether the conclusion is true or false. Should it be true,

he cannot solve the syllogism except by controverting one or both of

the premisses; but should the conclusion be false, two modes of

solution are open to him. One mode is, if he can point out an

equivocation or amphiboly in the terms of the conclusion; another

mode will be, to controvert, or exhibit a fallacy in, one of the

premisses.[102] The respondent, however, must learn to apply this

examination rapidly and unhesitatingly: to do so at once is very

difficult, though it may be easily done if he has leisure to

reflect.[103]

[Footnote 101: Soph. El. xviii. p. 176, b. 29: [Greek: ê( me/n

o)rthê\ lu/sis e)mpha/nisis pseudou=s sullogismou=, par' o(poi/an

e)rô/têsin sumbai/nei to\ pseu=dos.]]

[Footnote 102: Soph. El. xviii. p. 176, b. 38: [Greek: tou\s me\n

Mr. Poste translates these last words--"or by a counterproof directed

against the conclusion:" and he remarks in his note (pp. 145-147),

"that this assertion--disproof of the conclusion of the refutative

syllogism is one mode of _solution_--is both manifestly

inadmissible, and flatly contradicted by Aristotle himself

elsewhere." The words of Aristotle doubtless seem to countenance Mr.

Poste's translation; yet the contradiction pointed out by Mr. Poste

(and very imperfectly explained, p. 147) ought to make us look out

for another meaning; which is suggested by the chapter immediately

following (xix. p. 177, a. 9), where Aristotle treats of the

Fallacies of Equivocation and Amphiboly. He tells us that

equivocation may be found either in the conclusion or in the

premisses; and that to show it in the conclusion is one mode of

solving or invalidating the refutation. This is what Aristotle means

by the words cited at the beginning of this note: [Greek: tô=|

dei=xai to\ sumpe/rasma e)/chon ou)ch o)rthô=s]. In Mr. Poste's

translation these words mean the same as [Greek: a)nelei=n] used just

before, which Aristotle obviously does not intend.]

[Footnote 103: Soph. El. xviii. p. 177, a. 7.]

Aristotle then proceeds to indicate the modes in which the respondent

may provide solutions for each of the thirteen heads of fallacious

refutation above enumerated. For these thirteen classes, he

pronounces that one and the same solution will be found applicable to

all fallacies contained in one and the same class.[104]

[Footnote 104: Scholia, p. 312, a. 4, Br.; Soph. El. 20, p. 177, b.

31: [Greek: tô=n ga\r para\ tau)to\n lo/gôn ê( au)tê\ lu/sis], &c.]

Thus, in the two first of them--Equivocation of Terms and Amphiboly

of Propositions--duplicity of meaning must be either in the

conclusion, or in the premisses, of the refutative syllogism. If it

be in the conclusion, the refutation must at once be rejected, unless

the respondent has previously admitted some proposition containing

the equivocal word as one of its terms, so that the refutation may

appear to contradict it expressly and distinctly. But, if it be in

the premisses, then there is no necessity that the respondent should

have previously admitted such a proposition; for the equivocal word

may form the middle term of the refutative syllogism, and may thus

not appear in the conclusion thereof.[105] The proper way for the

respondent to deal with these questions, involving equivocation or

amphiboly, is to answer them, at the outset, with a reserve for the

double meaning, thus: "In one sense, it is so; in another sense, it

is not." If he does not perceive the double meaning until he has

already answered the first question, he must recover himself, when he

answers the second, by pointing out the equivocation more distinctly,

and by specifying how much he is prepared to concede.[106] Even if he

has been taken unawares, and has not perceived the equivocation until

the refutative syllogism has been constructed simply and absolutely,

he should still contend that he never meant to concede what has been

apparently refuted, and that the refutation tells only against the

name, not against the thing meant;[107] so that there is no genuine

refutation at all.

[Footnote 105: Soph. El. xix. p. 177, a. 18: [Greek: o(/sois d' e)n

toi=s e)rôtê/masin, ou)k a)na/gkê proapophê=sai to\ ditto/n; ou) ga\r

Instead of [Greek: a)\n kai/], Julius Pacius reads [Greek: ka)/n]:

the meaning is much the same.]

In the next two Fallacies--those of Composition and Division, or

Conjunction and Disjunction--when the questioner draws up his

refutative syllogism as if one of the two had been conceded, the

respondent will retort by saying that his concession was intended

only in the other construction of the words. This fallacy is distinct

from Equivocation; and it is a mistake to try (as some have tried) to

reduce all fallacies to Equivocation or Amphiboly.[108] The

respondent will distinguish, in each particular case, that

construction of the words which he intended in his admission, from

that which the questioner assumes in his pretended refutation.[109]

[Footnote 108: Soph. El. xx. p. 177, a. 33-b. 9. [Greek: ou) pa/ntes

oi( e)/legchoi para\ to\ ditto/n, katha/per tine/s phasin.]

This is another of the evidences showing that there were theorists

prior to Aristotle on logical proof; and that his declaration of

originality (in the concluding chapter of Sophist. Elenchi) must be

taken with reserve.]

[Footnote 109: Soph. El. xx. p. 177, b. 10-26: [Greek: diairete/on

ou)=n tô=| a)pokrinome/nô|;] &c.]

The Fallacies of Accent rarely furnish sophistical refutations,[110]

but those of _Figura Dictionis_ furnish a great many. When two words

have the like form and structure, it may naturally be imagined that

the signification of one belongs to the same Category as that of the

other. But this is often an illusion; and in such cases a sophistical

refutation may be founded thereupon. The respondent will solve it by

denying the inference from similarity of form to similarity of

meaning, and by distinguishing accurately to which among the ten

Categories the meaning of each several word or each proposition

belongs. When two words thus seem, by their form, to belong to the

same Category, the questioner will often take it for granted, without

expressly asking, that they do belong to the same, and will found a

confutation thereupon; but the respondent must not admit the

confutation to be valid, unless this question has been explicitly put

to him and conceded.[111] A question is put which, in its direct and

obvious meaning, bears only on the category of Quantity, of Quality,

of Relation, of Action, or of Passion; but the respondent, not aware

of the equivocation, answers it in such a manner as to comprehend the

Category of Substance, and is so understood by the questioner when he

constructs his refutative syllogism. The respondent will secure

himself from being thus confuted, by keeping constantly in view to

which of the Categories his answer is intended to refer.[112]

[Footnote 110: Ibid. xxi. p. 177, b. 35.]

[Footnote 111: Ibid. xxii. p. 178, a. 4-28. [Greek: to\ ga\r loipo\n

au)to\s prosti/thêsin o( a)kou/ôn ô(s o(moi/ôs lego/menon; to\ de\

le/getai me\n ou)ch o(moi/ôs, phai/netai de\ dia\ tê\n le/xin.]]

[Footnote 112: Several illustrative examples of this mode of

sophistical refutation, founded on the Fallacy called _Figura

Dictionis_, are indicated in this chapter by Aristotle. The

indication however, is often so brief and elliptical, that there is

great difficulty in restoring the fallacies in full, and still

greater difficulty in translating them into any modern language.

1. Is it possible at the same time to do and to have done the same

thing?--No. To see something is to do something; to have seen

something is to have done something?--Yes. Is it possible at the same

time to see and to have seen the same thing?--Yes.

The respondent has thus contradicted himself. The form of the word

[Greek: o(ra=n] appears to rank it under the Category [Greek:

poiei=n]. However, I think that the mistake really made here was,

that the respondent returned an answer universally negative to the

first question.

2. Does anything coming under the Category _Pati_ come under the

Category _Agere_?--No. But [Greek: te/mnetai, kai/etai,

ai)stha/netai], all show by their form that they belong to the

Category _Pati_?--Yes. Again, [Greek: le/gein, tre/chein, o(ra=n],

show by their form that they belong to the Category _Agere_?--Yes.

You will admit, however, that [Greek: to\ o(ra=n] is [Greek:

ai)stha/nesthai/ ti]?--Certainly. Therefore something that belongs to

the Category _Agere_ belongs also to that of _Pati_.

If we turn back to Aristot. Categ. viii. p. 11, a. 37, we shall find

that he admits the possibility that the same subject may belong to

two distinct Categories.

3. Did any one write that which stands here written?--Yes. It stands

here written that you are standing up--a false statement; but when it

was written the statement was true?--Yes. Therefore the writer has

written a statement both true and false?--Yes.

Here _true_ and _false_ belong to the Category Quality; the statement

or matter written belongs to that of Substance. What the writer wrote

had nothing to do with the former of the two Categories; and no

contradiction has been made out by admitting that the statement _was_

once true and _is_ now false.

4. Does a man tread that which he walks?--Yes. But he walks the whole

day?--Yes. Therefore he treads the whole day.

Here the Category of _Quando_ is confused with that of Substance.

5. But the most interesting illustration of this confusion of one

Category with another, is furnished by Aristotle in respect of the

difference between himself and Plato as to Ideas or Universals.

According to Plato the universal term denoted a separate something

apart from the particulars, yet of which each of these particulars

partook. According to Aristotle it denoted nothing separate from the

particulars, but something belonging (essentially or non-essentially)

to all and each of the particulars. In the Platonic theory it was an

_Hoc Aliquid_ ([Greek: to/de ti]), or had an existence substantive

and separate: in the Aristotelian it was a _Quale_ or _Quale Quid_

([Greek: poio/n]), having an existence merely adjective or

predicative. Aristotle maintains that Plato or the Platonists placed

it in the wrong Category--in the Category of Substance instead of in

that of Quality.

Now it is by rectifying this confusion of Categories that Aristotle

solves two argumentative puzzles which he ranks as sophistical:--(1)

The argument concluding in what was called the 'Third Man;' (2) The

following question: Koriskus, and the musical Koriskus--are these the

same, or is the second different from the first?

What is called the 'Third Man' was a refutation of the Platonic

theory of Ideas. Because Plato recognized a substantive existence,

corresponding to each common denomination connoting likeness, apart

from all the similar particulars denominated, _e.g._, a Self-man, or

separate self-existent man, corresponding to the Idea, and apart from

all individual men, Caius, &c.--opponents argued against him,

saying:--If this is recognized, you must also recognize that the

Self-man, and the individual man called Caius, have also a common

denomination and similarity, which (upon your principles) corresponds

to another Ideal Man, or a Third Man. You must, therefore, go on

inferring upwards to a Fourth Man, a Fifth Man, &c., and so onwards

to an indefinite number of Ideal Men, one above the other. This was

intended as a refutation, by _Reductio ad Impossibile_, of the

Platonic view of Ideas as separate Entities, each of them One and

Universal. But Aristotle here treats it as a Sophistical Refutation;

and he indicates what he calls the solution of it by saying that it

confounds the Categories of Substance and Quality, putting the

Universal (which ought to be under the Category of Quality) under the

Category of Substance. He has no right, however, to include this

among Sophistical Refutations, which are (as he himself defines them)

not real but fallacious refutations, invented by a dishonest

money-getting profession called Sophists, and which are solved by

pointing out the precise seat of the fallacy. The refutation called

the 'Third Man' is so far from being fallacious, that it is valid,

and is recited as such elsewhere by Aristotle himself (Metaphs. A. ix.

p. 990, b. 17**); while the solution tendered by Aristotle, instead of

being a solution, is a confirmation, pointing out, not where the

fallacy of the refutation resides but, where the fallacy of the

doctrine refuted resides. Moreover, if we are to treat the refutation

called the 'Third Man' as sophistical, we must number Plato himself

among the dishonest class called Sophists. Here is one among the many

proofs that the strong line drawn by Aristotle between the

Dialectician and the Sophist is quite untenable. The argument is

distinctly enunciated in the Platonic Parmenides (pp. 131-133).

The meaning of the Universal (Aristotle maintains) must be considered

as predicative only, tacked on to some _Hoc Aliquid_, and belonging

to _Quale_ or some other of the nine latter Categories. It may be set

out as a distinct subject for logical consideration and reasoning:

but it cannot be set out as a distinct existence beyond and apart

from its particulars ([Greek: para\ tou\s pollou\s e(/n ti]). It is

[Greek: poio/n], and it cannot even be recognized as [Greek: o(/per

poio/n] or [Greek: au)to-poio/n], for this would put it apart from

all the other [Greek: poia/], and would be open to the refutation

above noticed called the 'Third Man.' Such is the drift of the very

difficult passage of the Sophistici Elenchi (xxii. p. 178, b. 37-p.

179, a. 10**). I differ from Mr. Poste's translation (p. 71) of part

of this passage, and still more from the explanation given in the

latter part of his note (p. 155). I think that the doctrine of

[Greek: to\ e(\n para\ ta\ polla/] is produced by Aristotle here and

elsewhere in his work as untrue and inadmissible, not as his own

doctrine. Mr. Poste understands this passage differently from the

previous translators, with whom I agree for the most part, though M.

Barthélemy St. Hilaire appears to me to have missed the hinge upon

which Aristotle's argument turns, by translating [Greek: o(/per

poio/n]--id ipsum, quod quale est (J. Pacius)--"une qualité:" the

argument turns upon the distinction between [Greek: o(/per poio/n]

and [Greek: poio/n].

I come now to the second sophistical refutation given by Aristotle:

Koriskus, and the musician Koriskus--are the two the same or

different? This is what Aristotle calls a sophistical or fallacious

argument (compare Metaphys. E. ii. p. 1026, b. 15); but it can hardly

be so called with propriety, for the only solution that Aristotle

himself gives of it is, that the two are _idem numero_, but in an

improper or secondary sense (Topic. I. vii. p. 103, a. 30); _i. e._,

that they are in one point of view the same, in another point of view

different--they are [Greek: e(\n kata\ sumbebêko/s]. See Arist.

Metaph. [Greek: D]. vi. p. 1015, b. 16; Scholia, p. 696, a. 22, seq.;

and Alexand. Aphrodis. ad Metaph. pp. 321, 322, 414, 415, ed. Bonitz.

I understand Aristotle to say that [Greek: Ko/riskos mousiko/s]

cannot be properly _set out_ or abstracted ([Greek: ou)k e)/stin

au)to\ e)kthe/sthai]), because it includes two Categories (Substance

and Quality) in one; wherefore it cannot be properly compared either

with [Greek: Ko/riskos] simply (Category of Substance) or with

[Greek: mousiko/s] simply (Category of Quality). It seems strange

that Aristotle does not notice this argumentative difficulty in the

discussion which he bestows on [Greek: tau)to/n] in the Seventh Book

of the Topica. The subtle reasonings, very hard to follow, which

Aristotle employs (Physic. V. iv. p. 227) might have made him

cautious in treating the difficulties of opponents as so many

dishonest cavils. It is curious that Alexander, in reciting the

sophistical argument, assumes as a matter of course that [Greek: o(

grammatiko\s Sôkra/tês] is [Greek: o( au)to\s tô=| Sôkra/tei] (Schol.

ad Metaphys. p. 736, b. 26, Brand.).]

As a general rule, in all the refutations founded on the seven

Fallacies _In Dictione_, the respondent will solve the refutation by

distinguishing the double meaning of the words or of the phrase, and

by adopting as his own the one opposite to that which the questioner

proceeds upon. If the Fallacy is of Conjunction and Disjunction, and

if the questioner assumes Conjunction, the respondent will adopt

Disjunction; if it be a Fallacy of Accent, and if the questioner

assumes the grave accent, the respondent will adopt the acute.[113]

[Footnote 113: Soph. El. xxiii. p. 179, a. 11-25.]

Passing to the Fallacies _Extra Dictionem_, where the sophistical

refutation is founded upon a Fallacy of Accident, the respondent

ought to apply one and the same solution to all. He will say: "The

conclusion does not necessarily follow from the premisses"; and he

will be prepared with an example, in which the conclusion obtained

under this fallacy is notoriously untrue.[114] "Do you know

Koriskus?"--"Yes." "Do you know the distant person coming this

way?"--"No." "That distant person is Koriskus: therefore you know,

and you do not know, the same person." The inference here is not

necessary. To be coming this way--is an accident of Koriskus; and,

because you do not know the accident, we cannot infer that you do

not know the subject; such may or may not be the case.[115]

[Footnote 114: Soph. El. xxiv. p. 179, a. 30: [Greek: r(ête/on ou)=n

sumbibasthe/ntas o(moi/ôs pro\s a(/pantas o(/ti ou)k a)nagkai=on;

e)/chein de\ dei= prophe/rein to\ oi(=on.]]

[Footnote 115: Ibid. a. 35-b. 7.]

The major premiss upon which the preceding sophistical refutation

must rest, is, That it is impossible both to know and not to know the

same thing. This must be put as a direct question by the questioner,

and must be conceded by the respondent, before the intended

refutation can be made good. Now there are some persons who solve the

refutation by answering this question in the negative, and by saying

that it is possible both to know and not to know the same thing, only

not in the same respect: such is the case when we know Koriskus, but

do not know Koriskus approaching from a distance.[116] Aristotle

disapproves this mode of solution, as well as another mode which

refers the fallacy to equivocation of terms. He points out that there

are many other sophistical refutations, coming under the general head

of _Fallaciæ Accidentis_, to which such solution will not apply; and

that there ought to be one uniform mode of solution applicable to

every fallacy coming under the same general head; though he admits at

the same time that particular sophistical refutations may be vicious

in more than one way. He says, moreover, that this contradiction or

negation of the premiss is no true solution; for a solution ought to

bring to view clearly the reason why the fallacious refutation

appears to be a real refutation. Thus the _Fallacia Accidentis_

consists in an inference that what is true of an accident is true

also of the subject thereof: you explain that such inference, though

apparently cogent, has no real cogency, and in that explanation

consists the only proper solution of the fallacy.[117]

[Footnote 116: Ibid. b. 7, 18, 37: [Greek: lu/ousi de/ tines

a)nairou=ntes tê\n e)rô/têsin; phasi\ ga\r e)nde/chesthai tau)to\

pra=gma ei)de/nai kai\ a)gnoei=n, a)lla\ mê\ kata\ tau)to/.]

Mr. Poste (pp. 152-157) translates [Greek: a)nairou=ntes tê\n

e)rô/têsin]--"contradicting the thesis," and he expresses his

surprise at the assertion, observing (very truly) that contradiction

of the thesis is the very opposite of a solution; it helps in the

very work which the refutation aims at accomplishing. But I cannot

think that [Greek: e)rô/têsis] does mean "the thesis," either here or

in the other passage to which Mr. Poste refers (xxii. p. 178, b. 14).

I think it means a premiss which the respondent has conceded, or must

be presumed to have conceded, essential to the validity of the

refutation. The term [Greek: e)rô/têsis] cannot surely, with any

propriety, be applied to the thesis. It means either a question, or

what is conceded in reply to a question; and the _thesis_ cannot come

under either one meaning or the other, being the proposition which

the respondent sets out by affirming and undertakes to defend.]

[Footnote 117: Soph. El. xxiv. p. 179, b. 23: [Greek: ê)=n ga\r ê(

lu/sis e)mpha/nisis pseudou=s sullogismou=, par' o(\ pseudê/s.]]

In like manner, all those Fallacies which come under the general head

of _A dicto Secundum Quid ad dictum Simpliciter_, can only be solved

by pointing out, in each particular case, in what terms this

confusion is concealed--wherein resides the inference apparently

cogent which is mistaken for one really cogent. The respondent is

driven to an apparent contradiction, by having granted premisses from

which the inference is derivable that both sides of the _Antiphasis_

are true--that the same predicate A may be both affirmed and denied

of the same subject B. He solves the contradiction by analysing the

_Antiphasis_, and by showing that affirmation is _secundum quid_,

while denial is _simpliciter_; and that there is a contradiction not

real, but only apparent, between the two.[118]

[Footnote 118: Ibid. xxv. p. 180, a. 23-31.]

In like manner, the Fallacy _Ignoratio Elenchi_ will be solved by

analysing the two supposed counter-propositions of the _Antiphasis_,

and by showing that there is no real contradiction or inconsistency

between them.[119]

[Footnote 119: Ibid. xxvi. p. 181, a. 1-14.]

In regard to the Fallacies under _Petitio Principii_, the respondent

if he perceives that the premiss asked of him involves such a

fallacy, must refuse to grant it, however probable it may be in

itself. If he does not perceive this until after he has granted it,

he must throw back the charge of mal-procedure upon the questioner;

declaring that an Elenchus involving assumption of the matter in

question is null, and that the concession was made under the

supposition that some separate and independent syllogism was in

contemplation.[120]

[Footnote 120: Ibid. xxvii. p. 181, a. 15-21.]

There are two distinct ways in which the _Fallacia Consequentis_ may

be employed. The predicate may be an universal, comprehending the

subject: because animal always goes along with man, it is falsely

inferred that man always goes along with animal; or it is falsely

inferred that not-animal always goes along with not-man. The fallacy

is solved when this is pointed out. The last inference is only valid

when the terms are inverted; if animal always goes along with man,

not-man will always go along with not-animal.[121]

[Footnote 121: Ibid. xxviii. p. 181, a. 22-30. [Greek: a)na/palin

ga\r ê( a)kolou/thêsis].]

If the sophistical refutation includes more premisses than are

indispensable to the conclusion, the respondent, after having

satisfied himself that this is the fact, will point out the

mal-procedure of the questioner, and will say that he conceded the

superfluous premiss, not because it was in itself probable but,

because it seemed relevant to the debate; while nevertheless the

questioner has made no real or legitimate application of it towards

that object.[122] This is the mode of solution applicable in the case

of the Fallacies coming under the head _Non Causa pro Causâ_.[123]

[Footnote 122: Soph. El. xxix. p. 181, a. 31-35.]

[Footnote 123: Schol. p. 318, a. 36, Br.]

Where the sophistical questioner tries to refute by the _Fallacia

Plurium Interrogationum_ (_i.e._, by putting two or more questions as

one), the respondent should forthwith divide the complex question

into its component simple questions, and make answer accordingly. He

must not give one answer, either affirmative or negative, to that

which is more than one question. Even if he does give one answer, he

may sometimes not involve himself in any contradiction; for it may

happen that the same predicate is truly affirmable, or truly

deniable, of two or more distinct and independent subjects. Often,

however, the contrary is the case: no one true answer, either

affirmative or negative, can be given to one of these complex

questions: the one answer given, whatever it be, must always be

partially false or inconsistent.[124] Suppose two subjects, A and B,

one good, the other bad: if the question be, Whether A and B are good

or bad, it will be equally true to say--Both are good, or, Both are

bad, or, Both are neither good nor bad. There may indeed be other

solutions for this fallacy: Both or All may signify two or more items

taken individually, or taken collectively; but the only sure

precaution is--one answer to one question.[125]

[Footnote 124: Soph. El. xxx. p. 181, a. 38: [Greek: ou)/te plei/ô

kath' e(no\s ou)/te e(\n kata\ pollô=n, a)ll' e(\n kath' e(no\s

phate/on ê)\ a)pophate/on.]]

[Footnote 125: Ibid. b. 6-25.]

Suppose that, instead of aiming at a seeming refutation, the Sophist

tries to convict the respondent of Tautology. The source of this

embarrassment is commonly the fact that a relative term is often used

and conveys clear meaning without its correlate, though the correlate

is always implied and understood. The respondent must avoid this trap

by refusing to grant that the relative has any meaning at all without

its correlate; and by requiring that the correlate shall be

distinctly enunciated along with it. He ought to treat the relative

without its correlate as merely a part of the whole significant

expression--as merely syncategorematic; just as ten is in the

phrase--ten minus one, or as the affirmative word is in a negative

proposition.[126] Thus he will not recognize double as significant by

itself without its correlate half, nor half without its correlate

double; although in common parlance such correlate is often

understood without being formally enunciated.

Mr. Poste observes in his note:--"The sophistic locus of tautology

may be considered as a caricature of a dialectic locus. One fault

which dialectic criticism finds with a definition is the introduction

of superfluous words." He then cites Topic. VI. ii. (p. 141, a. 4,

seq.); but in this passage we find that the repetition of the same

word is declared not to be an argumentative impropriety, so that the

Sophist would gain nothing by driving his opponent into tautology.]

Lastly, another purpose which Aristotle ascribes to the Sophist, is

that of driving the respondent into a Solecism--into some grammatical

or syntactical impropriety, such as, using a noun in the wrong case

or gender, using a pronoun with a different gender or number from the

noun to which it belongs, &c. He points out that the solution of

these verbal puzzles must be different for each particular case; in

general, when thrown into a regular syllogistic form, even the

questioner himself will be found to speak bad Greek. The examples

given by Aristotle do not admit of being translated into a modern

language, so as to preserve the solecism that constitutes their

peculiarity.[127]

[Footnote 127: Soph. El. xxxii. p. 182, a. 7-b. 5.]

After having thus gone through the different artifices ascribed to

the Sophist, and the ways of solving or meeting them, Aristotle

remarks that there are material distinctions between the different

cases which fall under one and the same general head of Sophistical

Paralogism. Some cases there are in which both the fallacy itself,

and the particular point upon which it turns, are obvious and

discernible at first sight. In other cases, again, an ordinary person

does not perceive that there is any fallacy at all; or, if he does

perceive it, he often does not detect the seat of the fallacy, so

that one man will refer the case to one general head, and another, to

a different one.[128] Thus, for example, Fallacies of Equivocation

are perhaps the most frequent and numerous of all fallacies; some of

them are childish and jocular, not really imposing upon any one; but

there are others again in which the double meaning of a word is at

first unnoticed, and is disputed even when pointed out, so that it

can only be brought to light by the most careful and subtle analysis.

This happens especially with terms that are highly abstract and

general: which are treated by many, including even **philosophers

like Parmenides and Zeno, as if they were not equivocal at all, but

univocal.[129] Again, the _Fallaciæ Accidentis_, and the other

classes _Extra Dictionem_, are also often hard to detect. On the

whole, it is often hard to determine, not merely to which of the

classes any case of fallacy belongs, but even whether there is any

fallacy at all--whether the refutation is, or is not, a valid one.[130]

The pungent arguments in debate are those which bite most keenly, and

create the greatest amount of embarrassment and puzzle.[131] In

dialectical debate a puzzle arises, when the respondent finds that a

correct syllogism has been established against him, and when he does

not at once see which among its premisses he ought to controvert, in

order to overthrow the conclusion. In the eristic or sophistic debate

the puzzle of the respondent is, in what language to enunciate his

propositions so as to keep clear of the subtle objections which will

be brought against him by the questioner.[132] It is these pungent

arguments that most effectually stimulate the mind to investigation.

The most pungent of all is, where the syllogistic premisses are

highly probable, yet where they nevertheless negative a conclusion

which is also highly probable. Here we have an equal antithesis as to

presumptive credibility, between the premisses taken together on one

side and the conclusion on the other.[133] We do not know whether it

is in the premisses only, or in the conclusion, that we are to look

for untruth: the conclusion, though improbable, may yet be true,

while we may find that the true conclusion has been obtained from

untrue premisses; or the conclusion may be both improbable and

untrue, in which case we must look for untruth in one of the

premisses also--either the major or the minor. This is the most

embarrassing position of all. Another, rather less embarrassing, is,

where our thesis will be confuted unless we can show the confuting

conclusion to be untrue, but where each of the premisses on which the

conclusion depends is equally probable, so that we do not at once see

in which of them the cause of its untruth is to be sought. These two

are the most pungent and perplexing argumentative conjunctures of

dialectical debate.

it is given by Bekker, Waitz, Bussemaker, and Mr. Poste. The editions

anterior to Bekker had the additional words [Greek: ê)\

kataskeua/zê|] after [Greek: a)nairê=|] in the fourth line; and M.

Barthélemy St. Hilaire in his translation defends and retains them.

Bekker and the subsequent editors have omitted them, but have

retained the last words [Greek: ê)\ kataskeua/sei] in the seventh

line. To me this seems inconsistent: the words ought either to be

retained in both places or omitted in both. I think they ought to be

omitted in both. I have enclosed them in brackets in the fifth line.

This difficult passage (not well explained by Alexander, Schol. p.

320, b. 9) requires the explanations of Waitz and Mr. Poste. The note

of Mr. Poste is particularly instructive, because he expands in full

(p. 164) the three "similar syllogisms" to which Aristotle here

briefly alludes. The phrase [Greek: metatitheme/nês tê=s

a)ntipha/seôs] is determined by a passage in Analyt. Priora, II.

viii. p. 59, b. 1: it means "employment of the contradictory of the

conclusion, in combination with either one of the premisses, to upset

the other." The original syllogism is assumed to have two premisses,

each highly probable, while the conclusion is highly improbable,

being the negation of a highly probable proposition. The original

syllogism will stand thus: All M is P; All S is M; _Ergo_, All S is

P: the two premisses being supposed highly probable, and the

conclusion highly improbable. Of course, therefore, the contradictory

of the conclusion will be highly probable--Some S is not P. We take

this contradictory and employ it to construct two new syllogisms as

follows:--"All M is P; Some S is not P; _Ergo_ Some S is not M. And

again, Some S is not P: All S is M; _Ergo_, Some M is not P. All

these three syllogisms are similar in this respect: that each has two

highly probable premisses, while the conclusion is highly

improbable.]

But in eristic or sophistic debate our greatest embarrassment as

respondents will arise when we do not at once see whether the

refutative syllogism brought against us is conclusive or not, and

whether it is to be solved by negation or by distinction.[134] Next

in order as to embarrassment stands the case, where we see in which

of the two processes (negation or distinction) we are to find our

solution, yet without seeing on which of the premisses we are to

bring the process to bear; or whether, if distinction be the process

required, we are to apply it to the conclusion, or to one of the

premisses.[135] A defective syllogistic argument is silly, when the

deficient points are of capital importance--relating to the minor or

to the middle term, or when the assumptions are false and strange;

but it will sometimes be worthy of attention, if the points deficient

are outlying and easily supplied; in which cases it is the

carelessness of the questioner that is to blame, rather than the

argument itself.[136] Both the line of argument taken by the

questioner, and the mode of solution adopted by the respondent, may

be directed towards any one of three distinct purposes: either to the

thesis and main subject discussed; or to the adversary personally

(_i.e._, to the particular way in which he has been arguing); or to

neither of these, but simply to prolong the discussion (_i.e._,

against time). The solution may thus be sometimes such that it would

take more time to argue upon it than the patience of the auditors

will allow.[137]

[Footnote 134: Soph. El. xxxiii. p. 183, a. 7.]

Mr. Poste translates these last words very correctly:--"Whether it is

one of the premisses or the conclusion that requires distinction."

Here Aristotle again speaks of a mode of solution furnished by

applying _distinction_ ([Greek: diai/resis]) to _the conclusion_ as

well as to the premisses, though he does not say that solution can be

furnished by applying _disproof_ ([Greek: a)nai/resis]) to _the

conclusion_. See my remarks, a few pages above, on Mr. Poste's note

respecting ch. xviii. (supra, p. 406).]

[Footnote 136: Soph. El. xxxiii. p. 183, a. 14-20.]

[Footnote 137: Ibid. a. 21.]

The last chapter of the Sophistici Elenchi is employed by Aristotle

in recapitulating the scope and procedure of the nine Books of Topica

(reckoning the Sophistici Elenchi as the Ninth, as we ought in

propriety to do); and in appreciating the general bearing and value

of that treatise, having regard to the practice and theory of the

day.

The business of Dialectic and Peirastic is to find and apply the

syllogizing process to any given thesis, with premisses the most

probable that can be obtained bearing on the thesis. This Aristotle

treats as the proper function of Dialectic _per se_ and of Peirastic;

considering both--the last, of course--as referring wholly to the

questioner. His purpose is to investigate and impart this syllogizing

power--the power of questioning and cross-examining a respondent who

sets up a given thesis, so as to drive him into inconsistent answers.

It appears that Aristotle would not have cared to teach the

respondent how he might defend himself against this procedure, if

there had not happened to be another art--Sophistic, closely

bordering on Dialectic and Peirastic. He considers it indispensable

to furnish the respondent with defensive armour against sophistical

cross-examination; and this could not be done without teaching him at

the same time modes of defence against the cross-examination of

Dialectic and Peirastic. For this reason it is (Aristotle **tells

us[138]) that he has included in the Topica precepts on the best mode

of defending the thesis by the most probable arguments, as well as of

impugning it. The respondent professes to know (while the questioner

does not), and must be taught how to maintain his thesis like a man

of knowledge. Sokrates, the prince of dialecticians, did nothing but

question and cross-examine: he would never be respondent at all; for

he explicitly disclaimed knowledge. And if it were not for the

neighbourhood of Sophistic, Aristotle would have thought it

sufficient to teach a procedure like that of Sokrates. It was the

danger from sophistical cross-examination that led him to enlarge his

scheme--to unmask the Sophists by enumerating the paralogisms

peculiar to them, and to indicate the proper scheme of the responses

and solutions whereby the respondent might defend himself against

them. We remember that Aristotle treats all paralogisms and fallacies

as if they belonged to a peculiar art or profession called Sophistic,

and as if they were employed by Sophists exclusively; as if the

Dialecticians and the Peirasts, including among them Sokrates and

Plato, put all their questions without ever resorting to or falling

into paralogisms.

It appears to me that in one line of this remarkable passage a word

has dropped out which is necessary to the sense. We now read (about

the middle) [Greek: ô(s ou) mo/non pei=ran du/natai labei=n

dialektikô=s, a)lla\ kai\ ô(s ei)dô/s]. Now the words [Greek: pei=ran

labei=n] as the passage stands, must be construed along with [Greek:

ô(s ei)dô/s], and this makes no meaning at all, or an inadmissible

meaning. I think it clear that the word [Greek: u(pe/chein] or

[Greek: dou=nai] has dropped out before [Greek: ei)dô/s]. The passage

will then stand:--[Greek: ô(s ou) mo/non pei=ran du/natai labei=n

dialektikô=s, a)lla\ kai\ _u(pe/chein_] (or [Greek: _dou=nai_) ô(s

ei)dô/s]. When this verb is supplied the sense will be quite in

harmony with what follows, which at present it is not. [Greek:

Pei=ran labei=n] applies to the questioner, but not to the

respondent; [Greek: ô(s ei)dô/s] applies to the respondent, but not

to the questioner; [Greek: pei=ran u(pe/chein] applies to the

respondent, and is therefore the fit concomitant of [Greek: ô(s

ei)dô/s]. The translation given by Mr. Poste _first_

(p. 93):--"professing not only to test knowledge with the resources

of Dialectic, but also to maintain any thesis with the infallibility

of science" appears to me (excepting the word _infallibility_, which

is unsuitable) to render Aristotle's thought, though not his words as

they now stand; but Mr. Poste has given what he thinks an amended

translation (p. 175):--"Since it claims the power of catechizing or

cross-examining not only dialectically but also scientifically." This

second translation may approach more nearly to the present words of

Aristotle, but it departs more widely from his sense and doctrine.

Aristotle does not claim for either Dialecticians or Sophists the

power of cross-examining scientifically. He ascribes to the Sophists

nothing but cavil and fallacy--verbal and extra-verbal--the pretence

and sham of being wise or knowing (Soph. El. i., ii. p. 165).]

Aristotle, we have already more than once seen, asserts emphatically

his claim to originality as having been the first to treat these

subjects theoretically, and to suggest precepts founded on the

theory. On all important subjects (he remarks) the elaboration of any

good theory is a gradual process, the work of several successive

authors. The first beginnings are very imperfect and rudimentary;

upon these, however, subsequent authors build, both correcting and

enlarging, until, after some considerable time, a tolerably complete

scheme or system comes to be constructed. Such has been the case with

Rhetoric and other arts. Tisias was the first writer and preceptor on

Rhetoric, yet with poor and insufficient effect. To him succeeded

Thrasymachus, next Theodorus, and various others; from each of whom

partial improvements and additions were derived, until at length we

have now (it is Aristotle that speaks) a copious body of rhetorical

theory and precept, inherited from predecessors and accumulated by

successive traditions. Compared with this, the earliest attempt at

theory was indeed narrow and imperfect; but it was nevertheless the

first step in a great work, and, as such, it was the most difficult

and the most important. The task of building on a foundation already

laid, is far easier.[139]

While rhetorical theory has thus been gradually worked up to

maturity, the case has been altogether different with Dialectic. In

this I (Aristotle) found no basis prepared; no predecessor to follow;

no models to copy. I had to begin from the beginning, and to make

good the first step myself. The process of syllogizing had never yet

been analysed or explained by any one; much less had anything been

set forth about the different applications of it in detail. I worked

it out for myself, without any assistance, by long and laborious

application.[140] There existed indeed paid teachers, both in

Dialectic and in Eristic (or Sophistic); but their teaching has been

entirely without analysis, or theory, or system. Just as rhetoricians

gave to their pupils orations to learn by heart, so these dialectical

teachers gave out dialogues to learn by heart upon those subjects

which they thought most likely to become the topics of discourse.

They thus imparted to their pupils a certain readiness and fluency;

but they communicated no art, no rational conception of what was to

be sought or avoided, no skill or power of dealing with new

circumstances.[141] They proceeded like men, who, professing to show

how comfortable covering might be provided for the feet, should not

teach the pupil how he could make shoes for himself, but should

merely furnish him with a good stock of ready-made shoes--a present

valuable indeed for use, but quite unconnected with any skill as an

artificer. The syllogism as a system and theory, with precepts

founded on that theory for Demonstration and Dialectic, has

originated first with me (Aristotle). Mine is the first step, and

therefore a small one, though worked out with much thought and hard

labour: it must be looked at as a first step, and judged with

indulgence. You, my readers, or hearers of my lectures, if you think

that I have done as much as can fairly be required for an initiatory

start, compared with other more advanced departments of theory, will

acknowledge what I have achieved, and pardon what I have left for

others to accomplish.[142]

Cicero, in describing his own treatise De Oratore, insists upon the

marked difference between his mode of treatment and the common

rhetorical precepts; he claims to have followed the manner of the

Aristotelian Dialogues:--"Scripsi Aristoteleo more, quemadmodum

quidem volui, tres libros in disputatione ac dialogo de Oratore, quos

arbitror Lentulo tuo fore non inutiles. Abhorrent enim a communibus

præceptis, atque omnem antiquorum et Aristoteleam et Isocrateam

rationem oratoriam complectuntur" (Cicero, Epist. ad Famill. i. 9).]

It would seem that by [Greek: toi=s theasame/nois] Aristotle means to

address the readers of the present treatise, while by [Greek: tô=n

ê)kroame/nôn] he designates those who had heard his oral expositions

on the same subject.]

Such is the impressive closing chapter of the Sophistici Elenchi. It

is remarkable in two ways: first, that Aristotle expressly addresses

himself to hearers and readers in the second person; next, that he

asserts emphatically his own claim to originality as a theorist on

Logic, and declares himself to have worked out even the first

beginnings of such theory by laborious application. I understand his

claim to originality as intended to bear, not simply on the treatise

called Sophistici Elenchi and on the enumeration of Fallacies therein

contained, but, in a larger sense, on the theory of the Syllogism; as

first unfolded in the Analytica Priora, applied to Demonstration in

the Analytica Posteriora, applied afterwards to Dialectic in the

Topica, applied lastly to Sophistic (or Eristic) in the Sophistici

Elenchi. The phrase, "Respecting the _process of syllogizing_,[143] I

found absolutely nothing prepared, but worked it out by laborious

application for myself"--seems plainly to denote this large

comprehension. And, indeed, in respect to Sophistic separately, the

remark of Aristotle that nothing whatever had been done before him,

would not be well founded: we find in his own treatise of the

Sophistici Elenchi allusion to various prior doctrines, from which he

dissents.[144] In these prior doctrines, however, his predecessors

had treated the sophistical modes of refutation without reference to

the Syllogism and its general theory.[145] It is against such

separation that Aristotle distinctly protests. He insists upon the

necessity of first expounding the Syllogism, and of discussing the

laws of good or bad Refutation as a corollary or dependant of the

syllogistic theory. Accordingly he begins this treatise by intimating

that he intends to deduce these laws from the first and highest

generalities of the subject;[146] and he concludes it by claiming

this method of philosophizing as original with himself.

CHAPTER XI.

PHYSICA AND METAPHYSICA.

Aristotle distinguishes, in clear and explicit language, a science

which he terms Wisdom, Philosophy, or First Philosophy; the

subject-matter of which he declares to be _Ens quatenus _Ens__,

together with the concomitants belonging to it as such. With this

Ontology the treatise entitled Metaphysica purports to deal, and the

larger portion of it does really so deal. At the same time, the line

that parts off Ontology from Logic (Analytic and Dialectic) on the

one hand, and from Physics on the other, is not always clearly marked.

For, though the whole process of Syllogism, employed both in Analytic

and Dialectic, involves and depends upon the Maxim of Contradiction,

yet the discussion of this Maxim is declared to belong to First

Philosophy;[1] while not only the four Aristotelian varieties of

Cause or Condition, and the distinction between Potential and Actual,

but also the abstractions Form, Matter and Privation, which play so

capital a part in the Metaphysica, are equally essential and equally

appealed to in the Physica.[2]

[Footnote 1: Metaphys. [Greek: G]. iii. p. 1005, a. 19-b. 11. Whether

that discussion properly belongs to _Philosophia Prima_, or not,

stands as the first [Greek: A)pori/a] enumerated in the list which

occupies Book B. in that treatise, p. 995, b. 4-13; compare K. i. p.

1059, a. 24.]

ed. Bonitz; p. 689, b. Schol. Br.]

If we include both what is treated in the Analytica Posteriora (the

scientific explanation of Essence and Definition) and what is treated

in the Physica, we shall find that nearly all the expository

processes employed in the Metaphysica are employed also in these two

treatises. To look upon the general notion as a cause, and to treat

it as a creative force (_der schöpferische Wesensbegriff_, to use the

phrase of Prantl and other German logicians[3]), belongs alike to the

Physica and to the Analytica Posteriora. The characteristic

distinction of the treatise entitled Metaphysica is, that it is

all-comprehensive in respect to the ground covered; that the

expository process is applied, not exclusively to any separate branch

of _Ens_, but to _Ens_ as a whole _quatenus Ens_--to all the varieties

of _Ens_ that admit of scientific treatment at all;[4] that the same

abstractions and analytical distinctions, which, both in the

Analytica and in the Physica, are indicated and made to serve an

explanatory purpose, up to a certain point--are in the Metaphysica

sometimes assumed as already familiar, sometimes followed out with

nicer accuracy and subtlety.[5] Indeed both the Physica and the

Metaphysica, as we read them in Aristotle, would be considered in

modern times as belonging alike to the department of Metaphysics.

The primary distinction and classification recognized by Aristotle

among Sciences or Cognitions, is, that of (1) Theoretical, (2)

Practical, (3) Artistic or Constructive.[6] Of these three divisions,

the second and third alike comprise both intelligence and action, but

the two are distinguished from each other by this--that in the

Artistic there is always some assignable product which the agency

leaves behind independent of itself, whereas in the Practical no such

independent result remains,[7] but the agency itself, together with

the purpose (or intellectual and volitional condition) of the agent,

is every thing. The division named Theoretical comprises intelligence

alone--intelligence of _principia_, causes and constituent elements.

Here again we find a tripartite classification. The highest and most

universal of all Theoretical Sciences is recognized by Aristotle as

Ontology (First Philosophy, sometimes called by him Theology) which

deals with all _Ens_ universally _quatenus Ens_, and with the _Prima

Moventia_, themselves immoveable, of the entire Kosmos. The two other

heads of Theoretical Science are Mathematics and Physics; each of

them special and limited, as compared with Ontology. In Physics we

scientifically study natural bodies with their motions, changes, and

phenomena; bodies in which Form always appears implicated with

Matter, and in which the principle of motion or change is immanent

and indwelling (_i.e._, dependent only on the universal _Prima

Moventia_, and not impressed from without by a special agency, as in

works of human art). In Mathematics, we study immoveable and

unchangeable numbers and magnitudes, apart from the bodies to which

they belong; not that they can ever be really separated from such

bodies, but we intellectually abstract them, or consider them

apart.[8]

[Footnote 6: Metaphys. E. i. p. 1025, b. 25.]

[Footnote 7: Ibid. b. 22.]

[Footnote 8: Metaphys. E. i. p. 1026; K. vii. p. 1064, a. 28-b. 14;

M. iii. pp. 1077-1078; Bonitz, Commentar. p. 284.]

Such is Aristotle's tripartite distribution of Theoretical or

Contemplative Science. In introducing us to the study of First

Philosophy, he begins by clearing up the meaning of the term _Ens_.

It is a term of many distinct significations; being neither univocal,

nor altogether equivocal, but something intermediate between the two,

or multivocal. It is not a generic whole, distributed exhaustively

among correlative species marked off by an assignable difference:[9]

it is an analogical whole, including several genera distinct from

each other at the beginning, though all of them branches derivative

from one and the same root; all of them connected by some sort of

analogy or common relation to that one root, yet not necessarily

connected with each other by any direct or special tie.

[Footnote 9: Metaphys. [Greek: G]. ii. p. 1003, a. 33-p. 1004, a. 5:

[Greek: to\ d' o)\n le/getai me\n pollachô=s, a)lla\ pro\s e(\n kai\

mi/an tina\ phu/sin, kai\ ou)ch o(mônu/m ôs--u(pa/rchei ga\r

eu)thu\s ge/nê e)/chonta to\ o)\n kai\ to\ e(/n.]

Compare K. iii. p. 1060, b. 32. See also above, ch. iii. p. 60, of

the present work.]

Of these various significations, he enumerates, as we have already

seen, four:--(1) _Ens_ which is merely concomitant with, dependent

upon, or related to, another _Ens_ as terminus; (2) _Ens_ in the

sense of the True, opposed to _Non-Ens_ in the sense of the False;

(3) _Ens_ according to each of the Ten Categories; (4) _Ens_

potentially, as contrasted with _Ens_ actually. But among these four

heads, the two last only are matters upon which science is

attainable, in the opinion of Aristotle. To these two, accordingly,

he **confines Ontology or First Philosophy. They are the only

two that have an objective, self-standing, independent, nature.

That which falls under the first head (_Ens per Accidens_) is

essentially indeterminate; and its causes, being alike indeterminate,

are out of the reach of science. So also is that which falls under

the second head--_Ens tanquam verum_, contrasted with _Non-Ens

tanquam falsum_. This has no independent standing, but results from

an internal act of the judging or believing mind, combining two

elements, or disjoining two elements, in a way conformable to, or

non-conformable to, real fact. The true combination or disjunction is

a variety of _Ens_; the false combination or disjunction is a variety

of _Non-Ens_. This mental act varies both in different individuals,

and at different times with the same individual, according to a

multitude of causes often unassignable. Accordingly, it does not fall

under Ontological Science, nor can we discover any causes or

principles determining it.[10] When Aristotle says that the two first

heads are out of the reach of science, or not proper subjects of

science, he means that their first _principia_, causes, or deepest

foundations, cannot be discovered and assigned; for it is in

determining these _principia_ and causes that true scientific

cognition consists.[11]

[Footnote 10: Aristot. Met. E. iv. p. 1027, b. 17; [Greek: Th]. p.

1051, b. 2; p. 1052, a. 17-30; K. viii. p. 1065, a. 21.

There remains much obscurity about this meaning of _Ens_ (_Ens_

[Greek: ô(s a)lêthe/s]), even after the Scholia of Alexander (p. 701,

a. 10, Sch. Brand.), and the instructive comments of Bonitz,

Schwegler, and Brentano (Ueber die Bedeutung des Seienden nach

Aristoteles, ch. iii. pp. 21-39).

The foundation of this meaning of _Ens_ lies in the legitimate

_Antiphasis_, and the proper division thereof ([Greek: to\ de\

su/nolon peri\ merismo\n a)ntipha/seôs], p. 1027, b. 20). It is a

first principle (p. 1005, b. 30) that, if one member of the

_Antiphasis_ must be affirmed as true, the other must be denied as

false. If we fix upon the right combination to affirm, we say _the

thing that is_: if we fix upon the wrong combination and affirm it,

we say _the thing that is not_ (p. 1012, b. 10). "Falsehood and Truth

(Aristotle says, E. iv. p. 1027, b. 25) are not in things but in our

mental combination; and as regards simple (uncombined) matters and

essences, they are not even in our mental combination:" [Greek: ou)

ga/r e)sti to\ pseu=dos kai\ to\ a)lêthe\s e)n toi=s pra/gmasin,

e)stin ou)d' e)n tê=| dianoi/a|.] Compare Bonitz (ad Ar. Metaph. Z.

iv. p. 1030, a.), p. 310, Comm.

In regard to _cogitabilia_--simple, indivisible, uncompounded--there

is no combination or disjunction; therefore, strictly speaking,

neither truth nor falsehood (Aristot. De Animâ, III. vi. p. 430, a.

26; also Categor. x. p. 13, b. 10). The intellect either apprehends

these simple elements, or it does not apprehend them; there is no

[Greek: dia/noia] concerned. Not to apprehend them is ignorance,

[Greek: a)/gnoia], which sometimes loosely passes under the title of

[Greek: pseu=dos] (Schwegler, Comm. Pt. II., p. 32).]

There remain, as matter proper for the investigation of First

Philosophy, the two last-mentioned heads of _Ens_; viz., _Ens_

according to the Ten Categories, and _Ens_ potential and actual. But,

along with these, Aristotle includes another matter also; viz., the

critical examination of the Axioms and highest generalities of

syllogistic proof or Demonstration. He announces as the first

principle of these Axioms--as the highest and firmest of all

Principles--the Maxim of Contradiction:[12] The same predicate cannot

both belong and not belong to the same subject, at the same time and

in the same sense; or, You cannot both truly affirm, and truly deny,

the same predicate respecting the same subject; or, The same

proposition cannot be at once true and false. This Axiom is by nature

the beginning or source of all the other Axioms. It stands first in

the order of knowledge; and it neither rests upon nor involves any

hypothesis.[13]

[Footnote 12: Metaph. [Greek: G]. iii. p. 1005, b. 7, 17, 22, 34:

ei)=nai a)lêthei=s a(/ma ta\s a)ntikeime/nas pha/seis]--(He here

applies the term [Greek: do/xa] to designate this fundamental maxim.

This deserves notice, because of the antithesis, common with him

elsewhere, between [Greek: do/xa] and [Greek: e)pistê/mê]).]

[Footnote 13: Metaph. [Greek: G]. iii. p. 1005, b. 13-14: [Greek:

gnôrimôta/tên--a)nupo/theton].]

The Syllogism is defined by Aristotle as consisting of premisses and

a conclusion: if the two propositions called premisses be granted as

true, a third as conclusion must for that reason be granted as true

also.[14] The truth of the conclusion is affirmed conditionally on

the truth of the premisses; and the rules of Syllogism set out those

combinations of propositions in which such affirmation may be made

legitimately. The rules of the Syllogism being thus the rules for

such conditional affirmation, the Principle or Axiom thereof

enunciates in the most general terms what is implied in all those

rules, as essential to their validity. And, since the syllogistic or

deductive process is applicable without exception to every variety of

the _Scibile_, Aristotle considers the Axioms or Principles thereof

to come under the investigation of Ontology or First Philosophy. Thus

it is, that he introduces us to the Maxim of Contradiction, and its

supplement or correlative, the Maxim of the Excluded Middle.

[Footnote 14: Analyt. Prior. I. i. p. 24, b. 18-20, et alib.]

His vindication of these Axioms is very illustrative of the

philosophy of his day. It cannot be too often impressed that he was

the first either to formulate the precepts; or to ascend to the

theory, of deductive reasoning; that he was the first to mark by

appropriate terms the most important logical distinctions and

characteristic attributes of propositions; that before his time,

there was abundance of acute dialectic, but no attempt to set forth

any critical scheme whereby the conclusions of such dialectic might

be tested. Anterior to Sokrates, the cast of Grecian philosophy had

been altogether either theological, or poetical, or physical, or at

least some fusion of these three varieties into one. Sokrates was the

first who broke ground for Logic--for testing the difference between

good and bad ratiocination. He did this by enquiry as to the

definition of general terms,[15] and by dialectical exposure of the

ignorance generally prevalent among those who familiarly used them.

Plato in his Sokratic dialogues followed in the same negative track;

opening up many instructive points of view respecting the erroneous

tendencies by which reasoners were misled, but not attempting any

positive systematic analysis, nor propounding any intelligible scheme

of his own for correction or avoidance of the like. If Sokrates and

Plato, both of them active in exposing ratiocinative error and

confusion, stopped short of any wide logical theory, still less were

the physical philosophers likely to supply that deficiency. Aristotle

tells us that several of them controverted the Maxim of

Contradiction.[16] Herakleitus and his followers maintained the

negative of it, distinctly and emphatically;[17] while the disciples

of Parmenides, though less pronounced in their negative, could not

have admitted it as universally true. Even Plato must be reckoned

among those who, probably without having clearly stated to himself

the Maxim in its universal terms, declared doctrines quite

incompatible with it: the Platonic Parmenides affords a conspicuous

example of contradictory conclusions deduced by elaborate reasoning

and declared to be both of them firmly established.[18] Moreover, in

the Sophistes,[19] Plato explains the negative proposition as

expressing what is different from that which is denied, but nothing

beyond; an explanation which, if admitted, would set aside the Maxim

of Contradiction as invalid.

also the conclusion of the Platonic Parmenides, and the elaborate

dialectic or antinomies by which the contradictions involved in it

are proved.]

[Footnote 19: Plato, Sophistes, p. 257, B.]

While Aristotle mentions these various dissentients, and especially

Herakleitus, he seems to imagine that they were not really in

earnest[20] in their dissent. Yet he nevertheless goes at length into

the case against them, as well as against others, who agreed with him

in affirming the Maxim, but who undertook also to demonstrate it. Any

such demonstration Aristotle declares to be impossible. The Maxim is

assumed in all demonstrations; unless you grant it, no demonstration

is valid; but it cannot be itself demonstrated. He had already laid

down in the Analytica that the premisses for demonstration could not

be carried back indefinitely, and that the attempt so to carry them

back was unphilosophical.[21] There must be some primary,

undemonstrable truths; and the Maxim of Contradiction he ranks among

the first. Still, though in attempting any formal demonstration of

the Maxim you cannot avoid assuming the Maxim itself and thus falling

into _Petitio Principii_, Aristotle contends that you can demonstrate

it in the way of refutation,[22] relatively to a given opponent,

provided such opponent will not content himself with simply denying

it, but will besides advance some affirmative thesis of his own, as a

truth in which he believes; or provided he will even grant the fixed

meaning of words, defining them in a manner significant alike to

himself and to others,--each word to have either one fixed meaning,

or a limited number of different meanings, clear and well

defined.[23] It is impossible for two persons to converse, unless

each understands the other. A word which conveys to the mind not one

meaning, but a multitude of unconnected meanings, is for all useful

purposes unmeaning.[24] If, therefore, the opponent once binds

himself to an affirmative definition of any word, this definition may

be truly predicated of the _definitum_ as subject; while he must be

considered as interdicting himself from predicating of the same

subject the negative of that definition. But when you ask for the

definition, your opponent must answer the question directly and _bonâ

fide_. He must not enlarge his definition so as to include both the

affirmative and negative of the same proposition; nor must he tack on

to the real essence (declared in the definition) a multitude of

unessential attributes. If he answers in this confused and perplexing

manner, he must be treated as not answering at all, and as rendering

philosophical discussion impossible.[25] Such a mode of speaking goes

to disallow any ultimate essence or determinate subject, and shuts

out all predication; for there cannot be an infinite regress of

predicates upon predicates, and accidents upon accidents, without

arriving at an ultimate substratum--Subject or Essence.[26] If,

wherever you can truly affirm a predicate of any subject, you can

also truly deny the same predicate of the same subject, it is

manifest that all subjects are one: there is nothing to discriminate

man, horse, ship, wall, &c., from each other; every one speaks truth,

and every one at the same time speaks falsehood; a man believes and

disbelieves the same thing at the same time; or he neither believes

nor disbelieves, and then his mind is blank, like a vegetable.[27]

[Footnote 20: Aristot. Metaph. [Greek: G]. iii. p. 1005, b. 26; K. v.

p. 1062, a. 32. Here Aristotle intimates that Herakleitus may have

asserted what he did not believe; though we find him in another place

citing Herakleitus as an example of those who adhered as obstinately

to their opinions as other persons adhered to demonstrated truth

(Ethic. Nik. VII. v. p. 1146, b. 30.).]

The man who professes this doctrine, however (continues

Aristotle[28]), shows plainly by his conduct that his mind is not

thus blank; that**, in respect of the contradictory alternative, he

does not believe either both sides or neither side, but believes one

and disbelieves the other. When he feels hungry, and seeks what he

knows to be palatable and wholesome, he avoids what he knows to be

nasty and poisonous. He knows what is to be found in the

market-place, and goes there to get it; he keeps clear of falling into

a well or walking into the sea; he does not mistake a horse for a man.

He may often find himself mistaken; but he shows by his conduct that

he believes certain subjects to possess certain definite attributes,

and not to possess others. Though we do not reach infallible truth,

we obtain an approach to it, sometimes nearer, sometimes more remote;

and we thus escape the extreme doctrine which forbids all definite

affirmation.[29]

It is in this manner that Aristotle, vindicating the Maxims of

Contradiction and of Excluded Middle as the highest _principia_ of

syllogistic reasoning, disposes of the two contemporaneous dogmas

that were most directly incompatible with these Maxims:--(1) The

dogma of Herakleitus, who denied all duration or permanence of

subject, recognizing nothing but perpetual process, flux, or change,

each successive moment of which involved destruction and generation

implicated with each other: _Is_ and _is not_ are both alike and

conjointly true, while neither is true separately, to the exclusion

of the other;[30] (2) The dogma of Anaxagoras, who did not deny

fixity or permanence of subject, but held that everything was mixed

up with everything; that every subject had an infinite assemblage of

contrary predicates, so that neither of them could be separately

affirmed or separately denied: The truth lies in a third alternative

or middle, between affirmation and denial.[31]

Having thus refuted these dogmas to his own satisfaction, Aristotle

proceeds to impugn a third doctrine which he declares to be analogous

to these two and to be equally in conflict with the two syllogistic

_principia_ which he is undertaking to vindicate. This third doctrine

is the "_Homo Mensura_" of Protagoras: Man is the measure of all

things--the measure of things existent as well as of things

non-existent: To each individual that is true or false which he

believes to be such, and for as long as he believes it. Aristotle

contends that this doctrine is homogeneous with those of Herakleitus

and Anaxagoras, and must stand or fall along with them; all three being

alike adverse to the Maxim of Contradiction.[32] Herein he follows

partially the example of Plato, who (in his Theætêtus[33]), though

not formally enunciating the Maxim of Contradiction, had declared the

tenets of Protagoras to be coincident with or analogous to those of

Herakleitus, and had impugned both one and the other by the same line

of arguments. Protagoras agreed with Herakleitus (so Plato and

Aristotle tell us) in declaring both affirmative and negative (in the

contradictory alternative) to be at once and alike true; for he

maintained that what any person believed was true, and that what any

person disbelieved was false. Accordingly, since opinions altogether

opposite and contradictory are held by different persons or by the

same person at different times, both the affirmative and the negative

of every _Antiphasis_ must be held as true alike;[34] in other words,

all affirmations and all negations were at once true and false. Such

co-existence or implication of contradictions is the main doctrine of

Herakleitus.

I have already in another work,[35] while analysing the Platonic

dialogues Theætêtus and Kratylus, criticized at some length the

doctrine here laid down by Plato and Aristotle. I have endeavoured to

show that the capital tenet of Protagoras is essentially distinct

from the other tenets with which these two philosophers would

identify it: distinct both from the dogma of Herakleitus, That

everything is in unceasing flux and process, each particular moment

thereof being an implication of contradictions both alike true; and

distinct also from the other dogma held by others, That all cognition

is sensible perception. The Protagorean tenet "_Homo Mensura_" is

something essentially distinct from either of these two; though

possibly Protagoras himself may have held the second of the two,

besides his own. His tenet is nothing more than a clear and general

declaration of the principle of universal Relativity. True belief and

affirmation have no meaning except in relation to some believer, real

or supposed; true disbelief and negation have no meaning except in

relation to some disbeliever, real or supposed. When a man affirms

any proposition as true, he affirms only what he (perhaps with some

other persons also) believes to be true, while others may perhaps

disbelieve it as falsehood. Object and Subject are inseparably

implicated: we may separate them by abstraction, and reason about

each apart from the other; but, as reality, they exist only locked up

one with the other.

[Footnote 35: 'Plato and the Other Companions of Sokrates,' Vol. II.

c. xxvi. pp. 325-363: "The Protagorean doctrine--Man is the measure

of all things--is simply the presentation in complete view of a

common fact; uncovering an aspect of it which the received

phraseology hides. Truth and Falsehood have reference to some

believing subject--and the words have no meaning except in that

relation. Protagoras brings to view this subjective side of the same

complex fact, of which Truth and Falsehood denote the objective side.

He refuses to admit the object absolute--the pretended _thing in

itself_--Truth without a believer. His doctrine maintains the

indefeasible and necessary involution of the percipient mind in every

perception--of the concipient mind in every conception--of the

cognizant mind in every cognition. Farther, Protagoras acknowledges

many distinct believing or knowing Subjects: and affirms that every

object known must be relative to (or in his language, _measured by_)

the knowing Subject: that every _cognitum_ must have its

_cognoscens_, and every _cognoscibile_ its _cognitionis capax_; that

the words have no meaning unless this be supposed; that these two

names designate two opposite poles or aspects of the indivisible fact

of cognition--actual or potential--not two factors, which are in

themselves separate or separable, and which come together to make a

compound product. A man cannot in any case get clear of or discard

his own mind as a Subject. Self is necessarily omnipresent, concerned

in every moment of consciousness, &c." Compare also c. xxiv. p. 261.]

That such is and always has been the state of the fact, in regard to

truth and falsehood, belief and disbelief, is matter of notoriety:

Protagoras not only accepts it as a fact, but formulates it as a

theory. Instead of declaring that what he (or the oracle which he

consults and follows) believes to be true, is absolute truth, while

that which others believe, is truth relatively to them,--he lowers

his own pretensions to a level with theirs. He professes to be a

measure of truth only for himself, and for such as may be satisfied

with the reasons that satisfy him. Aristotle complains that this

theory discourages the search for truth as hopeless, not less than

the chase after flying birds.[36] But, however serious such

discouragement may be, we do not escape the real difficulty of the

search by setting up an abstract idol and calling it Absolute Truth,

without either relativity or referee; while, if we enter, as sincere

and _bonâ fide_ enquirers, on the search for reasoned truth or

philosophy, we shall find ourselves not departing from the

Protagorean canon, but involuntarily conforming to it. Aristotle,

after having declared that the Maxim of Contradiction was true beyond

the possibility of deception,[37] but yet that there were several

eminent philosophers who disallowed it, is forced to produce the best

reasons in his power to remove their doubts and bring them round to

his opinion. His reasons must be such as to satisfy not his own mind

only, but the minds of opponents and indifferent auditors as

referees. This is an appeal to other men, as judges each for himself

and in his own case: it is a tacit recognition of the autonomy of

each individual enquirer as a measure of truth to himself. In other

words, it is a recognition of the Protagorean canon.

[Footnote 36: Aristot. Metaph. [Greek: G]. v. p. 1009, b. 38.]

[Footnote 37: Ibid. [Greek: G]. iii. p. 1005, b. 11: [Greek:

bebaiota/tê d' a)rchê\ pasô=n, peri\ ê(\n diapseusthê=nai

a)du/naton.]]

We know little about the opinions of Protagoras; but there was

nothing in this canon necessarily at variance either with the Maxim

of Contradiction or with that of Excluded Middle. Both Aristotle and

Plato would have us believe that Protagoras was bound by his canon to

declare every opinion to be alike false and true, because every

opinion was believed by some and disbelieved by others.[38] But

herein they misstate his theory. He did not declare any thing to be

_absolutely_ true, or to be _absolutely_ false. Truth and Falsehood

were considered by him as always relative to some referee, and he

recognized no universal or infallible referee. In his theory the

necessity of _some_ referee was distinctly enunciated, instead of

being put out of sight under an ellipsis, as in the received theories

and practice. And this is exactly what Plato and Aristotle omit, when

they refute him. He proclaimed that each man was a measure for

himself alone, and that every opinion was true _to the believer_,

false _to the disbeliever_; while they criticize him as if he had

said--Every opinion is alike true and false; thus leaving out the

very qualification which forms the characteristic feature of his

theory. They commit that fallacy which Plato shows up in the

Euthydêmus, and which Aristotle[39] numbers in his list of _Fallaciæ

Extra Dictionem_, imputing it as a vice to the Sophists: they slide

_à dicto secundum quid ad dictum simpliciter_. And it is remarkable

that Aristotle, in one portion of his argument against "_Homo

Mensura_," expressly admonishes the Protagoreans that they must take

care to adhere constantly to this qualified mode of enunciation;[40]

that they must not talk of apparent truth generally, but of truth as

it appears _to themselves_ or _to some other persons_, now or at a

different time. Protagoras hardly needed such an admonition to keep

to what is the key-note and characteristic peculiarity of his own

theory; since it is only by suppressing this peculiarity that his

opponents make the theory seem absurd. He would by no means have

disclaimed that consequence of his theory, which Aristotle urges

against it as an irrefragable objection; viz., that it makes every

thing relative, and recognizes nothing as absolute. This is perfectly

true, and constitutes its merit in the eyes of its supporters.

Another argument of Aristotle[41] against the Protagorean "_Homo

Mensura_"--That it implies in every affirming Subject an equal

authority and equal title to credence, as compared with every other

affirming Subject--I have already endeavoured to combat in my review

of the Platonic Theætêtus, where the same argument appears fully

developed. The antithesis between Plato and Aristotle on one side,

and Protagoras on the other, is indeed simply that between Absolute

and Relative. The Protagorean doctrine is quite distinct from the

other doctrines with which they jumble it together--from those of

Herakleitus and Anaxagoras, and from the theory that Knowledge is

sensible perception. The real opponents of the Maxim of Contradiction

were Herakleitus, Anaxagoras, Parmenides, and Plato himself as

represented in some of his dialogues, especially the Parmenides,

Timæus, Republic, Sophistes. Each of these philosophers adopted a

First Philosophy different from the others: but each also adopted one

completely different from that of Aristotle, and not reconcileable

with his logical canons. None of them admitted determinate and

definable attributes belonging to determinate particular subjects,

each with a certain measure of durability.

[Footnote 41: Ibid. v. p. 1010, b. 11.]

Now the common speech of mankind throughout the Hellenic world was

founded on the assumption of such fixed subjects and predicates.

Those who wanted information for practical guidance or security,

asked for it in this form; those who desired to be understood by

others, and to determine the actions of others, adopted the like mode

of speech. Information was given through significant propositions,

which the questioner sought to obtain, and which the answer, if

cognizant, enunciated: _e.g._, Theætêtus **is sitting down[42]--to

repeat the minimum or skeleton of a proposition as given by Plato,

requiring both subject and predicate in proper combination, to convey

the meaning. Now the logical analysis, and the syllogistic precepts

of Aristotle,--as well as his rhetorical and dialectical suggestions

for persuading, for refuting, or for avoiding refutation--are all

based upon the practice of common speech. In conversing (he says) it

is impossible to produce and exhibit the actual objects signified;

the speaker must be content with enunciating, instead thereof, the

name significant of each.[43] The first beginning of rhetorical

diction is, to speak good Greek;[44] the rhetor and the dialectician

must dwell upon words, propositions, and opinions, not peculiar to

such as have received special teaching, but common to the many and

employed in familiar conversation; the auditors, to whom they address

themselves, are assumed to be commonplace men, of fair average

intelligence, but nothing beyond.[45] Thus much of acquirement is

imbibed by almost every one as he grows up, from the ordinary

intercourse of society. The men of special instruction begin with it,

as others do; but they also superadd other cognitions or

accomplishments derived from peculiar teachers. Universally--both in

the interior of the family, amidst the unscientific multitude, and by

the cultivated few--habitual speech was carried on through terms

assuming fixed subjects and predicates. It was this recognized

process in its two varieties of Analytic and Dialectic, which

Aristotle embraced in his logical theory, and to which he also

adapted his First Philosophy.

But the First Philosophy that preceded his, had not been so adapted.

The Greek philosophers, who flourished before dialectical discussion

had become active, during the interval between Thales and Sokrates,

considered Philosophy as one whole--_rerum divinarum et humanarum

scientia_--destined to render Nature or the Kosmos more or less

intelligible. They took up in the gross all those vast problems,

which the religious or mythological poets had embodied in divine

genealogies and had ascribed to superhuman personal agencies.

Thales and his immediate successors (like their predecessors the

poets) accommodated their hypotheses to intellectual impulses and

aspirations of their own; with little anxiety about giving

satisfaction to others,[46] still less about avoiding inconsistencies

or meeting objections. Each of them fastened upon some one grand and

imposing generalization (set forth often in verse) which he stretched

as far as it would go by various comparisons and illustrations, but

without any attention or deference to adverse facts or reasonings.

Provided that his general point of view was impressive to the

imagination,[47] as the old religious scheme of personal agencies was

to the vulgar, he did not concern himself about the conditions of

proof or disproof. The data of experience were altogether falsified

(as by the Pythagoreans)[48] in order to accommodate them to the

theory; or were set aside as deceptive and inexplicable from the

theory (as by both Parmenides and Herakleitus).[49]

But these vague hypotheses became subjected to a new scrutiny, when

the dialectical age of Zeno and Sokrates supervened. Opponents of

Parmenides impugned his theory of _Ens Unum Continuum Immobile_, as

leading to absurdities; while his disciple Zeno replied, not by any

attempt to disprove such allegations but, by showing that the

counter-theory of _Entia Plura Discontinua Moventia_, or _Mutabilia_,

involved consequences yet more absurd.[50] In the acute dialectical

warfare, to which the old theories thus stood exposed, the means of

attack much surpassed those of defence; moreover, the partisans of

Herakleitus despised all coherent argumentation, confining themselves

to obscure oracular aphorisms and multiplied metaphors.[51] In point

of fact, no suitable language could be found, consistently with

common speech or common experience, for expanding in detail either

the Herakleitean[52] or the Parmenidean theory; the former

suppressing all duration and recognizing nothing but events--a

perpetual stream of _Fientia_ or interchange of _Ens_ with _Non-Ens_;

the latter discarding _Non-Ens_ as unmeaning, and recognizing no real

events or successions, but only _Ens Unum_ perpetually lasting and

unchangeable. The other physical hypotheses, broached by Pythagoras,

Empedokles, Anaxagoras, and Demokritus, each altogether discordant

with the others, were alike imposing in their general enunciation and

promise, alike insufficient when applied to common experience and

detail.

Plato applies this remark to the theory of Protagoras; but the remark

belongs properly to that of Herakleitus.]

But the great development of Dialectic during the Sokratic age,

together with the new applications made of it by Sokrates and the

unrivalled acuteness with which he wielded it, altered materially the

position of these physical theories. Sokrates was not ignorant of

them;[53] but he discouraged such studies, and turned attention to

other topics. He passed his whole life in public and in

indiscriminate conversation with every one. He deprecated astronomy

and physics as unbecoming attempts to pry into the secrets of the

gods; who administered the general affairs of the Kosmos according to

their own pleasure, and granted only, through the medium of prophecy

or oracles, such special revelations as they thought fit. In his own

discussions Sokrates dwelt only on matters of familiar conversation

and experience--social, ethical, political, &c., such as were in

every one's mouth, among the daily groups of the market-place. These

he declared to be the truly _human_ topics[54]--the proper study of

mankind--upon which it was disgraceful to be ignorant, or to form

untrue and inconsistent judgments. He found, moreover, that upon

these topics no one supposed himself to be ignorant, or to require

teaching. Every one gave confident opinions, derived from intercourse

with society, embodied in the familiar words of the language, and

imbibed almost unconsciously along with the meaning of these words.

Now Sokrates not only disclaimed all purpose of teaching, but made

ostentatious profession of his own ignorance. His practice was to ask

information from others who professed to know; and with this view, to

question them about the import of vulgar words with the social

convictions contained in them.[55] To the answers given he applied an

acute cross-examination, which seldom failed to detect so much

inconsistency and contradiction as to cover the respondent with

shame, and to make him sensible that he was profoundly ignorant of

matters which he had believed himself to know well. Sokrates

declared, in his last speech before condemnation by the Athenian

Dikasts, that such false persuasion of knowledge, combined with real

ignorance, was universal among mankind; and that the exposure

thereof, as the great misguiding force of human life, had been

enjoined upon him as his mission by the Delphian God.[56]

The peculiarities which Aristotle ascribes to Sokrates are--that he

talked upon ethical topics instead of physical, that he fastened

especially on the definitions of general terms, and that his

discussions were inductive, bringing forward many analogous

illustrative or probative particulars to justify a true general

proposition, and one or a few to set aside a false one.[57] This

Sokratic practice is copiously illustrated both by Plato in many of

his dialogues, and by Xenophon throughout all the Memorabilia.[58] In

Plato, however, Sokrates is often introduced as spokesman of

doctrines not his own; while in Xenophon we have before us the real

man as he talked in the market-place, and apparently little besides.

Xenophon very emphatically exhibits to us a point which in Plato's

Dialogues of Search is less conspicuously marked, though still

apparent: viz., the power possessed by Sokrates of accommodating

himself to the ordinary mind in all its varieties--his habit of

dwelling on the homely and familiar topics of the citizen's daily

life--his constant appeal to small and even vulgar details, as the

way of testing large and imposing generalities.[59] Sokrates

possessed to a surprising degree the art of selecting arguments

really persuasive to ordinary non-theorizing men; so as often to

carry their assent along with him, and still oftener to shake their

previous beliefs, if unwarranted, or even if adopted by mere passive

receptivity without preliminary reflection and comparison.

Without departing from Aristotle's description, therefore, we may

conceive the change operated by Sokrates in philosophical discussion

under a new point of view. In exchanging Physics for Ethics, it

vulgarized both the topics and the talk of philosophy. Physical

philosophy as it stood in the age of Sokrates (before Aristotle had

broached his peculiar definition of Nature) was merely an obscure,

semi-poetical, hypothetical _Philosophia Prima_,[60] or rather

_Philosophia Prima_ and _Philosophia Secunda_ blended in one. This is

true of all its varieties,--of the Ionic philosophers as well as of

Pythagoras, Parmenides, Herakleitus, Anaxagoras, Empedokles, and even

Demokritus. Such philosophy, dimly enunciated and only half

intelligible,[61] not merely did not tend to explain or clear up

phenomenal experiences, but often added new difficulties of its own.

It presented itself sometimes even as discrediting, overriding, and

contradicting experience; but never as opening any deductive road

from the Universal down to its particulars.[62] Such theories, though

in circulation among a few disciples and opponents, were foreign and

unsuitable to the talk of ordinary men. To pass from these cloudy

mysteries to social topics and terms which were in every one's mouth,

was the important revolution in philosophy introduced in the age of

Sokrates, and mainly by him.

Aristotle indicates how much the _Philosophia Prima_ of his earlier

predecessors was uncongenial to and at variance with phenomenal

experience--Metaphys. A. v. p. 986, b. 31.

To shape their theories in such a way--[Greek: ta\ phaino/mena ei)

me/llei tis a)podô/sein] (Metaphys. [Greek: L]. viii. p. 1073, b.

36), was an obligation which philosophers hardly felt incumbent on

them prior to the Aristotelian age. Compare Simplikius (ad. Aristot.

Physic. I.), p. 328, a. 1-26, Schol. Br.; Schol. (ad. Aristot. De

Coelo III. I.) p. 509, a. 26-p. 510, a. 13.]

The drift of the Sokratic procedure was to bring men into the habit

of defining those universal terms which they had hitherto used

undefined, the definitions being verified by induction of particulars

as the ultimate authority. It was a procedure built upon common

speech, but improving on common speech; the talk of every man being

in propositions, each including a subject and predicate, but neither

subject nor predicate being ever defined. It was the mission of

Sokrates to make men painfully sensible of that deficiency, as well

as to enforce upon them the inductive evidence by which alone it

could be rectified. Now the Analytic and Dialectic of Aristotle grew

directly out of this Sokratic procedure, and out of the Platonic

dialogues in so far as they enforced and illustrated it. When

Sokrates had supplied the negative stimulus and indication of what

was amiss, together with the appeal to Induction as final authority,

Aristotle furnished, or did much to furnish, the positive analysis

and complementary precepts, necessary to clear up, justify, and

assure the march of reasoned truth.[63] What Aristotle calls the

syllogistic _principia_, or the principles of syllogistic

demonstration, are nothing else than the steps towards reasoned

truth, and the precautions against those fallacious appearances that

simulate it. The steps are stated in their most general terms, as

involving both Deduction and Induction; though in Aristotle we find

the deductive portion copiously unfolded and classified, while

Induction, though recognized as the only verifying foundation of the

whole, is left without expansion or illustration.

[Footnote 63: Though the theorizing and the analysis of Aristotle

presuppose and recognize the Sokratic procedure, yet, if we read the

Xenophontic Memorabilia, IV. vii., and compare therewith the first

two chapters of Aristotle's Metaphysica, in which he describes and

extols _Philosophia Prima_, we shall see how radically antipathetic

were the two points of view: Sokrates confining himself to practical

results--[Greek: me/chri tou= ô)phelimou=]; Aristotle extolling

_Philosophia Prima_, because it soars above practical results, and

serves as its own reward, elevating the philosopher to a partial

communion with the contemplative self-sufficiency of the Gods. Indeed

the remark of Aristotle, p. 983, a. 1-6, denying altogether the

jealousy ascribed to the Gods, &c., is almost a reply to the opinion

expressed by Sokrates, that a man by such overweening researches

brought upon himself the displeasure of the Gods, as prying into

their secrets (Xen. Mem. IV. vii. 6; I. i. 12).]

If we go through the Sokratic conversations as reported in the

Memorabilia of Xenophon, we shall find illustration of what has been

just stated: we shall see Sokrates recognizing and following the

common speech of men, in propositions combining subject and

predicate; but trying to fix the meaning of both these terms, and to

test the consistency of the universal predications by appeal to

particulars. The syllogizing and the inductive processes are

exhibited both of them in actual work on particular points of

discussion. Now on these processes Aristotle brings his analysis to

bear, eliciting and enunciating in general terms their _principia_

and their conditions. We have seen that he expressly declares the

analysis of these _principia_ to belong to First Philosophy.[64] And

thus it is that First Philosophy as conceived by Aristotle,

acknowledges among its _fundamenta_ the habits of common Hellenic

speech; subject only to correction and control by the Sokratic

cross-examining and testing discipline. He stands distinguished among

the philosophers for the respectful attention with which he collects

and builds upon the beliefs actually prevalent among mankind.[65]

Herein as well as in other respects his First Philosophy not only

differed from that of all the pre-Sokratic philosophers (such as

Herakleitus, Parmenides, Anaxagoras, &c.) by explaining the

_principia_ of Analytic and Dialectic as well as those of Physics and

Physiology, but it also differed from that of the post-Sokratic and

semi-Sokratic Plato, by keeping up a closer communion both with

Sokrates and with common speech. Though Plato in his Dialogues of

Search appears to apply the inductive discipline of Sokrates, and to

handle the Universal as referable to and dependent upon its

particulars; yet the Platonic _Philosophia Prima_ proceeds upon a

view totally different. It is a fusion of Parmenides with

Herakleitus;[66] divorcing the Universal altogether from its

particulars; treating the Universal as an independent reality and as

the only permanent reality; negating the particulars as so many

unreal, evanescent, ever-changing copies or shadows thereof.

Aristotle expressly intimates his dissent from the divorce or

separation thus introduced by Plato. He proclaims his adherence to

the practice of Sokrates, which kept the two elements together, and

which cognized particulars as the ultimate reality and test for the

Universal.[67] Upon this doctrine his First Philosophy is built:

being distinguished hereby from all the other varieties broached by

either his predecessors or contemporaries.

Aristotle: that it also included an intimate conjunction or fusion of

Parmenides with Herakleitus is made out in the ingenious Dissertation

of Herbart, De Platonici Systematis Fundamento, Göttingen (1805),

which winds up with the following epigrammatic sentence as result (p.

The Maxim of Contradiction, which Aristotle proclaims as the first

and firmest _principium_ of syllogizing, may be found perpetually

applied to particular cases throughout the Memorabilia of Xenophon

and the Sokratic dialogues of Plato. Indeed the Elenchus for which

Sokrates was so distinguished, is nothing more than an ever-renewed

and ingenious application of it; illustrating the painful and

humiliating effect produced even upon common minds by the shock of a

plain contradiction, when a respondent, having at first confidently

laid down some universal affirmative, finds himself unexpectedly

compelled to admit, in some particular case, the contradictory

negative. As against a Herakleitean, who saw no difficulty in

believing both sides of the contradiction to be true at once, the

Sokratic Elenchus would have been powerless. What Aristotle did was,

to abstract and elicit the general rules of the process; to classify

propositions according to their logical value, in such manner that he

could formulate clearly the structure of the two propositions between

which an exact contradictory antitheses subsisted. The important

logical distinctions between propositions _contradictory_ and

propositions _contrary_, was first clearly enunciated by Aristotle;

and, until this had been done, the Maxim of Contradiction could not

have been laid down in a defensible manner. Indeed we may remark

that, while this Maxim is first promulgated as a formula of First

Philosophy in Book [Greek: G]. of the Metaphysica, it had already

been tacitly assumed and applied by Aristotle throughout the De

Interpretatione, Analytica, and Topica, as if it were obvious and

uncontested. The First Philosophy of Aristotle was adapted to the

conditions of ordinary colloquy as amended and tested by Sokrates,

furnishing the theoretical basis of his practical Logic.
