CHAPTER XXI

THE SCEPTICS AND EPICUREANS

_Greek decay--The praises of Lucretius--Canonics--Physics--The proofs

of Lucretius--The atomic soul--Mental pleasures--Natural

pleasures--Lower philosophy and higher_

Philosophy, equally complete, equally perfect in all its parts, had its

final word in Plato and Aristotle; on the great lines of universal

knowledge no further really original structures were destined to be

raised by Greek hands. We have seen a parallelism between Greek

philosophy and Greek politics in their earlier phases (see above, p.

82); the same parallelism continues to the end. Greece broke the bonds

of her intense but narrow civic life and civic thought, and spread

herself out over the world in a universal monarchy and a cosmopolitan

philosophy; but with this widening of the area of her influence

reaction came and disruption and decay; an immense stimulus was given

on the one hand to the political activity, on the other, to the thought

and knowledge of the world as a whole, but at the centre Greece was

'living Greece no more,' her politics sank to the level of a dreary

farce, her philosophy died down to a dull and spiritless scepticism, to

an Epicureanism {211} that 'seasoned the wine-cup with the dust of

death,' or to a Stoicism not undignified yet still sad and narrow and

stern. The hope of the world, alike in politics and in philosophy,

faded as the life of Greece decayed.

[356]

The first phase of the change, _Scepticism_, or Pyrrhonism, as it was

named from its first teacher, need not detain us long. Pyrrho was

priest of Elis; in earlier life he accompanied Alexander the Great as

far as India, and is said to have become acquainted with certain of the

philosophic sects in that country. In his sceptical doctrine he had,

like his predecessors, a school with its succession of teachers; but

the [358] world has remembered little more of him or them than two

phrases 'suspense of judgment'--this for the intellectual side of

philosophy; 'impassibility'--this for the moral. The doctrine is a

negation of doctrine, the idle dream of idle men; even Pyrrho once,

when surprised in some sudden access of fear, confessed that it was

hard for him 'to get rid of the man in himself.' Vigorous men and

growing nations are never agnostic. They decline to rest in mere

suspense; they are extremely the opposite of impassive; they believe

earnestly, they feel strongly.

[365]

A more interesting, because more positive and constructive, personality

was that of Epicurus. This philosopher was born at Samos, in the year

341 B.C., of Athenian parents. He came to Athens in his eighteenth

year. Xenocrates was then teaching at {212} the Academy, Aristotle at

the Lyceum, but Epicurus heard neither the one nor the other. After

some wanderings he returned to Athens and set up on his [366] own

account as a teacher of philosophy. He made it a matter of boasting

that he was a self-taught philosopher; and Cicero (_De Nat. Deor._ i.

26) sarcastically remarks that one could have guessed as much, even if

Epicurus had not stated it himself; as one might of the proprietor of

an ugly house, who should boast that he had employed no architect. The

style of Epicurus was, in fact, plain and unadorned, but he seems all

the same to have been able to say what he meant; and few if any writers

ancient or modern have ever had so splendid a literary tribute, as

Epicurus had from the great Roman poet Lucretius, his follower and

expositor.

"Glory of the Greek race," he says, "who first hadst power to raise

high so bright a light in the midst of darkness so profound, shedding a

beam on all the interests of life, thee do I follow, and in the

markings of thy track do I set my footsteps now. Not that I desire to

rival thee, but rather for love of thee would fain call myself thy

disciple. For how shall the swallow rival the swan, or what speed may

the kid with its tottering limbs attain, compared with the brave might

of the scampering steed? Thou; O father, art the discoverer of nature,

thou suppliest to us a father's teachings, and from thy pages, {213}

illustrious one, even as bees sip all manner of sweets along the

flowery glades, we in like manner devour all thy golden words, golden

and right worthy to live for ever. For soon as thy philosophy, birth

of thy godlike mind, hath begun to declare the origin of things,

straightway the terrors of the soul are scattered, earth's walls are

broken apart, and through all the void I see nature in the working. I

behold the gods in manifestation of their power, I discern their

blissful seats, which never winds assail nor rain-clouds sprinkle with

their showers, nor snow falling white with hoary frost doth buffet, but

cloudless aether ever wraps them round, beaming in broad diffusion of

glorious light. For nature supplies their every want nor aught impairs

their peace of soul. But nowhere do I see any regions of hellish

darkness, nor does the earth impose a barrier to our sight of what is

done in the void beneath our feet. Wherefore a holy ecstasy and thrill

of awe possess me, while thus by thy power the secrets of nature are

disclosed to view" (Lucret. _De Nat. Rer._ iii, 1-30).

[367]

This devotion to the memory of Epicurus on the part of Lucretius was

paralleled by the love felt for him by his contemporaries; he had

crowds of followers who loved him and who were proud to learn his words

by heart. He seems indeed to have been a man of exceptional kindness

and amiability, and the 'garden of Epicurus' became proverbial as {214}

a place of temperate pleasures and wise delights. Personally we may

take it that Epicurus was a man of simple tastes and moderate desires;

and indeed throughout its history Epicureanism as a rule of conduct has

generally been associated with the finer forms of enjoyment, rather

than the more sensual. The 'sensual sty' is a nickname, not a

description.

[369]

Philosophy Epicurus defined as a process of thought and reasoning

tending to the realisation of happiness. Arts or sciences which had no

such practical end he contemned; and, as will be observed in Lucretius'

praises of him above, even physics had but one purpose or interest, to

free the soul from [370] terrors of the unseen. Thus philosophy was

mainly concerned with conduct, _i.e._ with Ethics, but secondarily and

negatively with Physics, to which was appended what Epicurus called

Canonics, or the science of testing, that is, a kind of logic.

[371]

Beginning with _Canonics_, as the first part of philosophy in order of

time, from the point of view of human knowledge, Epicurus laid it down

that the only source of knowledge was the senses, which gave us an

immediate and true perception of that which actually came into contact

with them. Even the visions of madmen or of dreamers he considered

were in themselves true, being produced by a physical cause of some

kind, of which these visions were the direct and immediate report.

Falsity came in with {215} people's interpretations or imaginations

with respect to these sensations.

Sensations leave a trace in the memory, and out of similarities or

analogies among sensations there are developed in the mind general

notions or types, such as 'man,' 'house,' which are also true, because

[373] they are reproductions of sensations. Thirdly, when a sensation

occurs, it is brought into relation in the mind with one or more of

these types or notions; this is _predication_, true also in so far as

its elements are true, but capable of falsehood, as subsequent or

independent sensation may prove. If supported or not contradicted by

sensation, it is or may be true; if contradicted or not supported by

sensation, it is or may be false. The importance of this statement of

the canon of truth or falsehood will be understood when we come to the

physics of Epicurus, at the basis of which is his theory of Atoms,

which by their very nature can never be directly testified to by

sensation.

[374]

This and no more was what Epicurus had to teach on the subject of

logic. He had no theory of definition, or division, or ratiocination,

or refutation, or explication; on all these matters Epicurus was, as

Cicero said, 'naked and unarmed.' Like most self-taught or ill-taught

teachers, Epicurus trusted to his dogmas; he knew nothing and cared

nothing for logical defence.

{216}

[375]

In his _Physics_ Epicurus did little more than reproduce the doctrine

of Democritus. He starts from the fundamental proposition that

'nothing can be produced from nothing, nothing can really perish.' The

veritable existences in nature are the Atoms, which are too minute to

be discernible by the senses, but which nevertheless have a definite

size, and cannot further be divided. They have also a definite weight

and form, but no qualities other than these. There is an infinity of

empty space; this Epicurus proves on abstract grounds, practically

because a limit to space is unthinkable. It follows that there must be

an infinite number of the atoms, otherwise they would disperse

throughout the infinite void and disappear. There is a limit, however,

to the number of varieties among the atoms in respect of form, size,

and weight. The existence of the void space is proved by the fact that

motion takes place, to which he adds the argument that it necessarily

exists also to separate the atoms one from another. So far Epicurus

and Democritus are agreed.

To the Democritean doctrine, however, Epicurus made a curious addition,

to which he himself is said to have attached much importance. The

natural course (he said) for all bodies having weight is downwards in a

straight line. It struck Epicurus that this being so, the atoms would

all travel for ever in parallel lines, and those 'clashings and

interminglings' of {217} atoms out of which he conceived all visible

forms to be produced, could never occur. He therefore laid it down

that the atoms _deviated_ the least little bit from the straight, thus

making a world possible. And Epicurus considered that this supposed

deviation of the atoms not only made a world possible, but human

freedom also. In the deviation, without apparent cause, of the

descending atoms, the law of necessity was broken, and there was room

on the one hand for man's free will, on the other, for prayer to the

gods, and for hope of their interference on our behalf.

It may be worth while summarising the proofs which Lucretius in his

great poem, professedly following in the footsteps of Epicurus, adduces

for these various doctrines.

Epicurus' first dogma is, 'Nothing proceeds from nothing,' that is,

every material object has some matter previously existing exactly equal

in quantity to it, out of which it was made. To prove this Lucretius

appeals to the _order of nature_ as seen in the seasons, in the

phenomena of growth, in the fixed relations which exist between life

and its environment as regards what is helpful or harmful, in the

limitation of size and of faculties in the several species and the

fixity of the characteristics generally in each, in the possibilities

of cultivation and improvement of species within certain limits and

under certain conditions.

{218}

To prove his second position, 'Nothing passes into nothing,' Lucretius

points out to begin with that there is a law even in destruction;

_force_ is required to dissolve or dismember anything; were it

otherwise the world would have disappeared long ago. Moreover, he

points out that it is from the elements set free by decay and death

that new things are built up; there is no waste, no visible lessening

of the resources of nature, whether in the generations of living

things, in the flow of streams and the fulness of ocean, or in the

eternal stars. Were it not so, infinite time past would have exhausted

all the matter in the universe, but Nature is clearly immortal.

Moreover, there is a correspondence between the structure of bodies and

the forces necessary to their destruction. Finally, apparent

violations of the law, when carefully examined, only tend to confirm

it. The rains no doubt disappear, but it is that their particles may

reappear in the juices of the crops and the trees and the beasts which

feed on them.

Nor need we be surprised at the doctrine that the atoms, so

all-powerful in the formation of things, are themselves invisible. The

same is true of the forest-rending blasts, the 'viewless winds' which

lash the waves and overwhelm great fleets. There are odours also that

float unseen upon the air; there are heat, and cold, and voices. There

is the process of evaporation, whereby we know that the water has gone,

{219} yet cannot see its vapour departing. There is the gradual

invisible detrition of rings upon the finger, of stones hollowed out by

dripping water, of the ploughshare in the field, and the flags upon the

streets, and the brazen statues of the gods whose fingers men kiss as

they pass the gates, and the rocks that the salt sea-brine eats into

along the shore.

That there is Empty Space or Void he proves by all the varied motions

on land and sea which we behold; by the porosity even of hardest

things, as we see in dripping caves. There is the food also which

disperses itself throughout the body, in trees and cattle. Voices pass

through closed doors, frost can pierce even to the bones. Things equal

in size vary in weight; a lump of wool has more of void in it than a

lump of lead. So much for Lucretius.

For abstract theories on physics, except as an adjunct and support to

his moral conceptions, Epicurus seems to have had very little

inclination. He thus speaks of the visible universe or Cosmos. [373]

The Cosmos is a sort of skyey enclosure, which holds within it the

stars, the earth, and all visible things. It is cut off from the

infinite by a wall of division which may be either rare or dense, in

motion or at rest, round or three-cornered or any other form. That

there is such a wall of division is quite admissible, for no object of

which we have observation is without its limit. Were this wall of

division to {220} break, everything contained within it would tumble

out. We may conceive that there are an infinite number of such Cosmic

systems, with inter-cosmic intervals throughout the infinity of space.

He is very disinclined to assume that similar phenomena, _e.g._

eclipses of the sun or moon, always have the same cause. The various

accidental implications and interminglings of the atoms may produce the

same effect in various ways. In fact Epicurus has the same impatience

of theoretical physics as of theoretical philosophy. He is a

'practical man.'

[378]

He is getting nearer his object when he comes to the nature of the

soul. The soul, like everything else, is composed of atoms, extremely

delicate and fine. It very much resembles the breath, with a mixture

of heat thrown in, sometimes coming nearer in nature to the first,

sometimes to the second. Owing to the delicacy of its composition it

is extremely subject to variation, as we see in its passions and

liability to emotion, its phases of thought and the varied experiences

without which we cannot live. It is, moreover, the chief cause of

sensation being possible for us. Not that it could of itself have had

sensation, without the enwrapping support of the rest of the structure.

The rest of the structure, in fact, having prepared this chief cause,

gets from it a share of what comes to it, but not a share of all which

the soul has.

The soul being of material composition equally {221} with the other

portions of the bodily structure, dies of course with it, that is, its

particles like the rest are dispersed, to form new bodies. There is

nothing dreadful therefore about death, for there is nothing left to

know or feel anything about it.

As regards the process of sensation, Epicurus, like Democritus,

conceived bodies as having a power of emitting from their surface

extremely delicate images of themselves. These are composed of very

fine atoms, but, in spite of their tenuity, they are able to maintain

for a considerable time their relative form and order, though liable

after a time to distortion. They fly with great celerity through the

void, and find their way through the windows of the senses to the soul,

which by its delicacy of nature is in sympathy with them, and

apprehends their form.

[379]

The gods are indestructible, being composed of the very finest and

subtlest atoms, so as to have not a body, but _as it were_ a body.

Their life is one of perfect blessedness and peace. They are in number

countless; but the conceptions of the vulgar are erroneous respecting

them. They are not subject to the passions of humanity. Anger and joy

are alike alien to their nature; for all such feelings imply a lack of

strength. They dwell apart in the inter-cosmic spaces. As Cicero

jestingly remarks: "Epicurus by way of a joke introduced his gods so

pure that you could see through them, {222} so delicate that the wind

could blow through them, having their dwelling-place outside between

two worlds, for fear of breakage."

[380]

Coming finally to Epicurus' theory of Ethics, we find a general

resemblance to the doctrine of Democritus and Aristippus. The end of

life is pleasure or the absence of pain. He differs, however, from the

Cyrenaics in maintaining that not the pleasure of the moment is the

end, but pleasure throughout the whole of life, and that therefore we

ought in our conduct to have regard to the future. Further he denies

that pleasure exists only in activity, it exists equally in rest and

quiet; in short, he places more emphasis in his definition on the

absence of pain or disturbance, than on the presence of positive

pleasure. And thirdly, while the Cyrenaics maintained that bodily

pleasures and pains were the keenest, Epicurus claimed these

characteristics for the pleasures of the mind, which intensified the

present feeling by anticipations of the future and recollections of the

past. And thus the wise man might be happy, even on the rack. Better

indeed was it to be unlucky and wise, than lucky and foolish. In a

similar temper Epicurus on his death-bed wrote thus to a friend: "In

the enjoyment of blessedness and peace, on this the last day of my life

I write this letter to you. Strangury has supervened, and the

extremest agony of internal {223} pains, yet resisting these has been

my joy of soul, as I recalled the thoughts which I have had in the

past."

[381]

We must note, however, that while mental pleasures counted for much

with the Epicureans, these mental pleasures consisted not in thought

for thought's sake in any form; they had nothing to do with

contemplation. They were essentially connected with bodily

experiences; they were the memory of past, the anticipation of future,

bodily pleasures. For it is to be remembered that thoughts were with

Epicurus only converted sensations, and sensations were bodily

processes. Thus every joy of the mind was conditioned by a bodily

experience preceding it. Or as Metrodorus, Epicurus' disciple, defined

the matter: "A man is happy when his body is in good case, and he has

good hope that it will continue so." Directly or indirectly,

therefore, every happiness came back, in the rough phrase of Epicurus,

to one's belly at last.

[382]

This theory did not, however, reduce morality to bestial

self-indulgence. If profligate pleasures could be had free from mental

apprehensions of another world and of death and pain and disease in

this, and if they brought with them guidance as to their own proper

restriction, there would be no reason whatever to blame a man for

filling himself to the full of pleasures, which brought no pain or

sorrow, that is, {224} no evil, in their train. But (Epicurus argues)

this is far from being the case. Moreover there are many pleasures

keen enough at the time, which are by no means pleasant in the

remembering. And even when we have them they bring no enjoyment to the

highest parts of our nature. What those 'highest parts' are, and by

what standard their relative importance is determined, Epicurus does

not say. He probably meant those parts of our nature which had the

widest range in space and time, our faculties, namely, of memory and

hope, of conception, of sight and hearing.

Moreover there are distinctions among desires; some are both natural

and compulsory, such as thirst; some are natural but not compulsory, as

the desire for dainties; some are neither natural nor compulsory, such

as the desire for crowns or statues. The last of these the wise man

will contemn, the second he will admit, but so as to retain his

freedom. For independence of such things is desirable, not necessarily

that we may reduce our wants to a minimum, but in order that if we

cannot enjoy many things, we may be content with few. "For I am

convinced," Epicurus continues, "that they have the greatest enjoyment

of wealth, who are least dependent upon it for enjoyment."

Thus if Epicurus did not absolutely teach simplicity of living, he

taught his disciples the necessity of being capable of such simplicity,

which they could {225} hardly be without practice. So that in reality

the doctrine of Epicurus came very near that of his opponents. As

Seneca the Stoic observed, "Pleasure with him comes to be something

very thin and pale. In fact that law which we declare for virtue, the

same law he lays down for pleasure."

One of the chief and highest pleasures of life Epicurus found in the

possession of friends, who provided for each other not only help and

protection, but a lifelong joy. For the 'larger friendship' of the

civic community, Epicurus seems to have had only a very neutral regard.

Justice, he says, is a convention of interests, with a view of neither

hurting or being hurt. The wise man will have nothing to do with

politics, if he can help it.

In spite of much that may offend in the doctrines of Epicurus, there is

much at least in the man which is sympathetic and attractive. What one

observes, however, when we compare such a philosophy with that of Plato

or Aristotle, is first, a total loss of constructive imagination. The

parts of the 'philosophy,' if we are so to call it, of Epicurus hang

badly together, and neither the Canonics nor the Physics show any real

faculty of serious thinking at all. The Ethics has a wider scope and a

more real relation to experience if not to reason. But it can never

satisfy the deeper apprehension of mankind.

The truest and most permanently valid revelations {226} of life come

not to the many but to the one or the few, who communicate the truth to

the many, sometimes at the cost of their own lives, always at the cost

of antagonism and ridicule. A philosophy therefore which only

represents in theoretical form the average practice of the average man,

comes into the world still-born. It has nothing to say; its hearers

know it all, and the exact value of it all, already. And in their

heart of hearts, many even of those who have stooped to a lower ideal,

and sold their birthright of hopes beyond the passing hour, for a mess

of pottage in the form of material success and easy enjoyment, have a

lurking contempt for the preachers of what they practise; as many a

slaveholder in America probably had for the clerical defenders of the

'divine institution.'

There is a wasting sense of inadequacy in this 'hand-to-mouth' theory

of living, which compels most of those who follow it to tread softly

and speak moderately. They are generally a little weary if not

cynical; they don't think much of themselves or of their success; but

they prefer to hold on as they have begun, rather than launch out into

new courses, which they feel they have not the moral force to continue.

"May I die," said the Cynic, "rather than lead a life of pleasure."

"May I die," says the Epicurean, "rather than make a fool of myself."

The Idealist is to them, if not {227} a hypocrite, at least a

visionary,--if not a Tartuffe, at least a Don Quixote tilting at

windmills. Yet even for poor Don Quixote, with all his blindness and

his follies, the world retains a sneaking admiration. It can spare a

few or a good many of its worldly-wisdoms, rather than lose altogether

its enthusiasms and its dreams. And the one thing which saves

Epicureanism from utter extinction as a theory, is invariably the

idealism which like a 'purple patch' adorns it here and there. No man

and no theory is wholly self-centred. Pleasure is supplanted by

Utility, and Utility becomes the greatest Happiness of the greatest

Number, and so, as Horace says (_Ep._ I. x. 24)--

Naturam expellas furca, tamen usque recurret,

Nature (like Love) thrust out of the door, will come back by the

window; and the Idealism which is not allowed to make pain a pleasure,

is required at last to translate pleasure into pains.
