[148]
Having got his principle of stability and his principle of change on an equal footing, Democritus next laid it down that all the differences visible in things were differences either of shape, of arrangement, or of position; practically, that is, he considered that what seem, to us to be qualitative differences in things, _e.g._ hot or cold, sweet or sour, green or yellow, are only resulting impressions from different shapes, or different arrangements, or different modes of presentation, among the atoms of which things are composed.
Coming now to that which _is_, Democritus, as against the Eleatics, maintained that this was not a unity, some one immovable, unchangeable existence, but an innumerable number of atoms, invisible by reason of their smallness, which career through empty s.p.a.ce (that which _is not_), and by their union bring objects into being, by their separation bring these to destruction. The action of these atoms on each other depended on the manner in which they were brought into contact; but in any case the unity of any object was only an apparent unity, it being really const.i.tuted of a mult.i.tude of interlaced and mutually related {77} particles, and all growth or increase of the object being conditioned by the introduction into the structure of additional atoms from without.
[149]
For the motions of the atoms he had no anterior cause to offer, other than necessity or fate. They existed, and necessarily and always had existed, in a state of whirl; and for that which always had been he maintained that no preceding cause could legitimately or reasonably be demanded.
[150]
Nothing, then, could come out of nothing; all the visible structure of the universe had its origin in the movements of the atoms that const.i.tuted it, and conditioned its infinite changes. The atoms, by a useful but perhaps too convenient metaphor, he called the _seeds_ of all things. They were infinite in number, though not infinite in the number, of their shapes. Many atoms were similar to each other, and this similarity formed a basis of union among them, a warp, so to speak, or solid foundation across which the woof of dissimilar atoms played to const.i.tute the differences of things.
[151]
Out of this idea of an eternal eddy or whirl Democritus developed a cosmogony. The lighter atoms he imagined flew to the outmost rim of the eddy, there const.i.tuting the heavenly fires and the heavenly aether. The heavier atoms gathered at the centre, forming successively air and water and the solid earth. Not that there was only one such {78} system or world, but rather mult.i.tudes of them, all varying one from the other; some without sun or moon, others with greater luminaries than those of our system, others with a greater number.
All, however, had necessarily a centre; all as systems were necessarily spherical.
[152]
As regards the atoms he conceived that when they differed in weight this must be in respect of a difference in their essential size. In this he was no doubt combating the notion that the atoms say of lead or gold were in their substance, taking equal quant.i.ties, of greater weight than atoms of water or air. The difference of weight in objects depended on the proportion which the atoms in them bore to the amount of empty s.p.a.ce which was interlaced with them. On the other hand, a piece of iron was lighter yet harder than a piece of lead of equal size, because of the special way in which the atoms in it were linked together. There were fewer atoms in it, but they were, in consequence of their structure and arrangement, more tightly strung.
[153]
In all this Democritus was with great resolution working out what we may call a strictly mechanical theory of the universe. Even the soul or life-principle in living creatures was simply a structure of the finest and roundest (and therefore most nimble) atoms, with which he compared the extremely attenuated dust particles visible in their never-ending {79} dance in a beam of light pa.s.sed into a darkened room.
This structure of exceeding tenuity and nimbleness was the source of the motion characteristic of living creatures, and provided that elastic counteracting force to the inward-pressing nimble air, whereby were produced the phenomena of respiration. Every object, in fact, whether living or not, kept its form and distinctive existence by its possession in degree of a kind of soul or spirit of resistance in its structure, adequate to counteract the pressure of external forces upon its particles.
[155]
Sensation and perception were forms in which these external forces acted upon the more nimble and lively existences, more particularly on living creatures. For every body was continually sending forth emanations or images resembling itself sufficiently in form and structure to affect perceptive bodies with an apprehension of that form and structure. These images travelled by a process of successive transmission, similar to that by which wave-motions are propagated in water. They were, in other words, not movements of the _particles_ of the objects, which latter must otherwise in time grow less and fade away, but a modification in the arrangement of the particles immediately next the object, which modification reproduced itself in the next following, and so on right through the medium to the perceptive body.
{80}
[156]
These images tended by extension in all directions to reach vast dimensions at times, and to influence the minds of men in sleep and on other occasions in strange ways. Hence men imagined G.o.ds, and attributed those mighty phenomena of nature--earthquakes, tempests, lightning and thunder, and dire eclipses of sun and moon, to the vaguely visible powers which they imagined they saw. There was indeed a soul or spirit of the universe, as there was a soul or spirit of every individual thing that const.i.tuted it. But this was only a finer system of atoms after all. All else is convention or dream; the only realities are Atoms and Emptiness, Matter and s.p.a.ce.
[157]
Of absolute verity through the senses we know nothing; our perceptions are only conventional interpretations of we know not what. For to other living creatures these same sensations have other meanings than they have to us, and even the same person is not always affected alike by the same thing; which then is the true of two differing perceptions we cannot say. And therefore either there is no such thing as truth, or, at all events, we know through the senses nothing of it. The only genuine knowledge is that which transcends appearances, and reasons out what is, irrespective of appearances,--in other words, the only genuine knowledge is that of the (atomic) philosopher. And his knowledge is {81} the result of the happy mixture of his atoms whereby all is in equal balance, neither too hot nor too cold. Such a man seeing in the mind's eye the whole universe a tissue of whirling and interlacing atoms, with no real mystery or terror before or after, will live a life of cheerful fearlessness, undisturbed by terrors of a world to come or of powers unseen. His happiness is not in feastings or in gold, but in a mind at peace. And three human perfections he will seek to attain: to reason rightly, to speak graciously, to do his duty.

CHAPTER IX
THE SOPHISTS
_Anarchic philosophy--Success not truth--Man the measure--All opinions true--Reductio ad absurdum_
A certain a.n.a.logy may perhaps be discerned between the progression of philosophic thought in Greece as we have traced it, and the political development which had its course in almost every Greek state during the same period. The Ionic philosophy may be regarded as corresponding with the _kingly_ era in Greek politics. Philosophy sits upon the heights and utters its authoritative dicta for the resolution of the seeming contradictions of things. One principle is master, but the testimony of the senses is not denied; a harmony of thought and sensation is sought in the interpretation of appearances by the light of a ruling idea. In Pythagoras and his order we have an _aristocratic_ organisation of philosophy. Its truths are for the few, the best men are the teachers, equal as initiated partakers in the mysteries, supreme over all outside their society. A reasoned and reasonable order and method are {83} symbolised by their theory of Number; their philosophy is political, their politics oligarchic. In the Eleatic school we have a succession of personal attempts to construct a _domination_ in the theory of Nature; some ideal conception is attempted to be so elevated above the data of sensation as to override them altogether, and the general result we are now to see throughout the philosophic world, as it was seen also throughout the world of politics, in a total collapse of the principle of forced authority, and a development, of successively nearer approaches to anarchic individualism and doubt. The notion of an ultimately true and real, whatever form it might a.s.sume in various theorists' hands, being in its essence apart from and even antagonistic to the perceptions of sense, was at last definitely cast aside as a delusion; what remained were the individual perceptions, admittedly separate, unreasoned, unrelated; Reason was dethroned, Chaos was king. In other words, what _seemed_ to any individual sentient being at any moment to be, that for him was, and nothing else was. The distinction between the real and the apparent was definitely attempted to be abolished, not as. .h.i.therto by rejecting the sensually apparent in favour of the rationally conceived real, but by the denial of any such real altogether.
The individualistic revolution in philosophy not {84} only, however, had a.n.a.logies with the similar revolution contemporaneously going on in Greek politics, it was greatly facilitated by it. Each, in short, acted and reacted on the other. Just as the sceptical philosophy of the Encyclopaedists in France promoted the Revolution, and the Revolution in its turn developed and confirmed the philosophic scepticism, so also the collapse of contending philosophies in Greece promoted the collapse of contending systems of political authority, and the collapse of political authority facilitated the growth of that individualism in thought with which the name of the Sophists is a.s.sociated.
[178]
Cicero (_Brut_. 12) definitely connects the rise of these teachers with the expulsion of the tyrants and the establishment of democratic republics in Sicily. From 466 to 406 B.C. Syracuse was democratically governed, and a 'free career to talents,' as in revolutionary France, so also in revolutionary Greece, began to be promoted by the elaboration of a system of persuasive argument. Devices of method called 'commonplaces' were constructed, whereby, irrespective of the truth or falsehood of the subject-matter, a favourable vote in the public a.s.semblies, a successful verdict in the public courts, might more readily be procured. Thus by skill of verbal rhetoric, the worse might be made to appear the better reason; and philosophy, so far as it continued its functions, {85} became a search, not for the real amidst the confusions of the seeming and unreal, but a search for the seeming and the plausible, to the detriment, or at least to the ignoring, of any reality at all.
The end of philosophy then was no longer universal truth, but individual success; and consistently enough, the philosopher himself professed the individualism of his own point of view, by teaching only those who were prepared to pay him for his teaching. All over Greece, with the growth of democracy, this philosophy of persuasion became popular; but it was to Athens, under Pericles at this time the centre of all that was most vivid and splendid in Greek life and thought, that the chief teachers of the new philosophy flocked from every part of the Greek world.
[177]
The first great leader of the Sophists was _Protagoras_. He, it is said, was the first to teach for pay; he also was the first to adopt the name of Sophist. In the word Sophist there was indeed latent the idea which subsequently attached to it, but as first used it seems to have implied this only, that _skill_ was the object of the teaching rather than _truth_; the new teachers professed themselves 'practical men,' not mere theorists.
The Greek word, in short, meant an able cultivated man in any branch of the arts; and the development of practical capacity was doubtless what Protagoras {86} intended to indicate as the purpose of his teaching, when he called himself a Sophist. But the ability he really undertook to cultivate was ability to _persuade_, for Greece at this time was nothing if not political; and persuasive oratory was the one road to political success. And as Athens was the great centre of Greek politics, as well as of Greek intellect, to Athens Protagoras came as a teacher.
He was born at Abdera, in Thrace (birthplace also of Democritus), in 480 B.C., began to teach at Athens about 451 B.C., and soon acquired great influence with Pericles, the distinguished leader of the Athenian democracy at this time. It is even alleged that when in 445 the Athenians were preparing to establish a colony at Thurii in Italy, Protagoras was requested to draw up a code of laws for the new state, and personally to superintend its execution.
After spending some time in Italy he returned to Athens, and taught there with great success for a number of years. Afterwards he taught for some time in Sicily, and died at the age of seventy, after [178]
about forty years of professional activity. He does not seem to have contented himself with the merely practical task of teaching rhetoric, but in a work which he, perhaps ironically, ent.i.tled _Truth_, he enunciated the principles on which he based his teaching. Those principles were summed up in the sentence, "Man (by which he meant _each_ man) is {87} the measure of all things, whether of their existence when they do exist, or of their non-existence when [179] they do not." In the development of this doctrine Protagoras starts from a somewhat similar a.n.a.lysis of things to that of Herac.l.i.tus and others.
Everything is in continual flux, and the apparently real objects in nature are the mere temporary and illusory result of the in themselves invisible movements and minglings of the elements of which they are composed; and not only is it a delusion to attempt to give a fact.i.tious reality to the things which appear, it is equally a delusion to attempt to separate the (supposed) thing perceived from the perception itself.
A thing is only as and when it is perceived. And a third delusion is to attempt to separate a supposed perceiving mind from the perception; all three exist only in and through the momentary perception; the supposed reality behind this, whether external in the object or internal in the mind, is a mere imagination. Thus the Herac.l.i.tean flux in Nature was extended to Mind also; only the sensation exists, and that only at the moment of its occurrence; this alone is truth, this alone is reality; all else is delusion.
[180]
It followed from this that as a man felt a thing to be, so for him it veritably was. Thus abstract truth or falsity could not be; the same statements could be indifferently true or false--to different {88} individuals at the same time, to the same individual at different times. It followed that all appearances were equally true: what seemed to be to any man, that was alone the true for him. The relation of such a doctrine as this to politics and to morals is not far to seek.
Every man's opinion was as good as another's; if by persuasion you succeeded in altering a man's opinion, you had not deceived the man, his new opinion was as true (to him) as the old one. Persuasiveness, therefore, was the only wisdom. Thus if a man is ill what he eats and drinks seems bitter to him, and it is so; when he is well it seems the opposite, and is so. He is not a wiser man in the second state than in the first, but the second state is pleasanter. If then you can persuade him that what he thinks bitter is really sweet, you have done him good. This is what the physician tries to do by his drugs; this is what the Sophist tries to do by his words. Virtue then is teachable in so far as it is possible to persuade a boy or a man by rhetoric that that course of conduct which pleases others is a pleasant course for him. But if any one happens not to be persuaded of this, and continues to prefer his own particular course of conduct, this _is_ for him the good course. You cannot blame him; you cannot say he is wrong. If you punish him you simply endeavour to supply the dose of unpleasantness which may {89} be needed to put the balance in his case on the same side as it already occupies in the case of other people.
It may be worth while to antic.i.p.ate a little, and insert here in summary the refutation of this position put into the mouth of Socrates by Plato in the _Theaetetus_: "But I ought not to conceal from you that there is a serious objection which may be urged against this doctrine of Protagoras. For there are states, such as madness and dreaming, in which perception is false; and half our life is spent in dreaming; and who can say that at this instant we are not dreaming? Even the fancies of madmen are real at the time. But if knowledge is perception, how can we distinguish between the true and the false in such cases? ...
Shall I tell you what amazes me in your friend Protagoras? 'What may that be?' I like his doctrine that what appears is; but I wonder that he did not begin his great work on truth with a declaration that a pig, or a dog-faced baboon, or any other monster which has sensation, is a measure of all things; then while we were reverencing him as a G.o.d he might have produced a magnificent effect by expounding to us that he was no wiser than a tadpole. For if truth is only sensation, and one man's discernment is as good as another's, and every man is his own judge, and everything that he judges is right and true, then {90} what need of Protagoras to be our instructor at a high figure; and why should we be less knowing than he is, or have to go to him, if every man is the measure of all things?" ... Socrates now resumes the argument. As he is very desirous of doing justice to Protagoras, he insists on citing his own words: 'What appears to each man is to him.'
"And how," asks Socrates, "are these words reconcilable with the fact that all mankind are agreed in thinking themselves wiser than others in some respects, and inferior to them in others? In the hour of danger they are ready to fall down and wors.h.i.+p any one who is their superior in wisdom as if he were a G.o.d. And the world is full of men who are asking to be taught and willing to be ruled, and of other men who are willing to rule and teach them. All which implies that men do judge of one another's impressions, and think some wise and others foolish. How will Protagoras answer this argument? For he cannot say that no one deems another ignorant or mistaken. If you form a judgment, thousands and tens of thousands are ready to maintain the opposite. The mult.i.tude may not and do not agree in Protagoras' own thesis, 'that man is the measure of all things,' and then who is to decide? Upon hip own showing must not his 'truth' depend on the number of suffrages, and be more or less true in proportion as he has more or fewer of them? And {91} [the majority being against him] he will be bound to acknowledge that they speak truly who deny him to speak truly, which is a famous jest. And if he admits that they speak truly who deny him to speak truly, he must admit that he himself does not speak truly. But his opponents will refuse to admit this as regards themselves, and he must admit that they are right in their refusal. The conclusion is, that all mankind, including Protagoras himself, will deny that he speaks truly; and his truth will be true neither to himself nor to anybody else" (Jowett, _Plato_, iv. pp. 239 _sqq._)
The refutation seems tolerably complete, but a good deal had to happen before Greece was ready to accept or Plato to offer such a refutation.
