The Cynics.
Antisthenes, the founder of the Cynic School, repeated the familiar propositions that virtue is founded upon knowledge, is teachable, and is one. But what aroused the admiration of Antisthenes was not Socrates, the man of intellect, the man of science, the philosopher, but Socrates, the man of independent character, who followed his own notions of right with complete indifference to the opinions of others. This independence was in fact merely a by-product of the Socratic life. Socrates had been independent of all earthly goods and possessions, caring neither for riches nor for applause, only because his heart was set upon a greater treasure, the acquisition of wisdom. Mere independence and indifference to the [{159}] opinions of others were not for him ends in themselves. He did not make fetishes of them. But the Cynics interpreted his teaching to mean that the independence of earthly pleasures and possessions is in itself the end and object of life. This, in fact, was their definition of virtue, complete renunciation of everything that, for ordinary men, makes life worth living, absolute asceticism, and rigorous self-mortification. Socrates, again, thinking that the only knowledge of supreme value is ethical knowledge, had exhibited a tendency to disparage other kinds of knowledge. This trait the Cynics exaggerated into a contempt for all art and learning so great as frequently to amount to ignorance and boorishness. "Virtue is sufficient for happiness," said Antisthenes, "and for virtue nothing is requisite but the strength of a Socrates; it is a matter of action, and does not require many words, or much learning." The Cynic ideal of virtue is thus purely negative; it is the absence of all desire, freedom from all wants, complete independence of all possessions. Many of them refused to own houses or any dwelling place, and wandered about as vagrants and beggars. Diogenes, for the same reason, lived in a tub. Socrates, following single-heartedly what he knew to be good, cared nothing what the vulgar said. But this indifference to the opinion of others was, like his independence of possessions, not an end in itself. He did not interpret it to mean that he was wantonly to offend public opinion. But the Cynics, to show their indifference, flouted public opinion, and gave frequent and disgusting exhibitions of indecency.
Virtue, for the Cynics, is alone good. Vice is the only evil. Nothing else in the world is either good or bad. [{160}] Everything else is "indifferent." Property, pleasure, wealth, freedom, comfort, even life itself, are not to be regarded as goods. Poverty, misery, illness, slavery, and death itself, are not to be regarded as evils. It is no better to be a freeman than a slave, for if the slave have virtue, he is in himself free, and a born ruler. Suicide is not a crime, and a man may destroy his life, not however to escape from misery and pain (for these are not ills), but to show that for him life is indifferent. And as the line between virtue and vice is absolutely definite, so is the distinction between the wise man and the fool. All men are divided into these two classes. There is no middle term between them. Virtue being one and indivisible, either a man possesses it whole or does not possess it at all. In the former case he is a wise man, in the latter case a fool. The wise man possesses all virtue, all knowledge, all wisdom, all happiness, all perfection. The fool possesses all evil, all misery, all imperfection.
The Cyrenaics.
For the Cyrenaics, too, virtue is, at least formally, the sole object of life. It is only formally, however, because they give to virtue a definition which robbed it of all meaning. Socrates had not infrequently recommended virtue on account of the advantages which it brings. Virtue, he said, is the sole path to happiness, and he had not refrained from holding out happiness as a motive for virtue. This did not mean, however, that he did not recognize a man's duty to do the right for its own sake, and not for the sake of the advantage it brings. "Honesty," we say, "is the best policy," [{161}] but we do not mean thereby to deny that it is the duty of men to be honest even if it is not, in some particular case, the best policy. Socrates, however, had not been very clear upon these points, and had been unable to find any definite basis for morality, other than that of happiness. It was this side of his teaching which Aristippus now pressed to its logical conclusions, regardless of all other claims. Doubtless virtue is the sole end of life, but the sole end of virtue is one's own advantage, that is to say, pleasure. One may as well say at once that the sole end of life is pleasure.
The influence of Protagoras and the Sophists also played its part in moulding the thought of Aristippus. Protagoras had denied the objectivity of truth, and the later Sophists had applied the same theory to morals. Each man is a law unto himself. There is no moral code binding upon the individual against his own wishes. Aristippus combined this with his doctrine of pleasure. Pleasure being the sole end of life, no moral law externally imposed can invalidate its absolute claims. Nothing is wicked, nothing evil, provided only it satisfies the individual's thirst for pleasure.
Whether such a philosophy will lead, in practice, to the complete degradation of its devotees, depends chiefly upon what sort of pleasure they have in mind. If refined and intellectual pleasures are meant, there is no reason why a comparatively good life should not result. If bodily pleasures are intended, the results are not likely to be noble. The Cyrenaics by no means wholly ignored the pleasures of the mind, but they pointed out that feelings of bodily pleasure are more potent and intense, and it was upon these, therefore, that they chiefly [{162}] concentrated their attention. Nevertheless they were saved from the lowest abysses of sensuality and bestiality by their doctrine that, in the pursuit of pleasure, the wise man must exercise prudence. Completely unrestrained pursuit of pleasure leads in fact to pain and disaster. Pain is that which has to be avoided. Therefore the wise man will remain always master of himself, will control his desires, and postpone a more urgent to a less urgent desire, if thereby in the end more pleasure and less pain will accrue to him. The Cyrenaic ideal of the wise man is the man of the world, bent indeed solely upon pleasure, restrained by no superstitious scruples, yet pursuing his end with prudence, foresight, and intelligence. Such principles would, of course, admit of various interpretations, according to the temperament of the individual. We may notice two examples. Anniceris, the Cyrenaic, believed indeed that pleasure is the sole end, but set such store upon the pleasures that arise from friendship and family affection, that he admitted that the wise man should be ready to sacrifice himself for his friends or family--a gleam of light in the moral darkness. Hegesias, a pessimist, considered that positive enjoyment is impossible of attainment. In practice the sole end of life which can be realized is the avoidance of pain.
The Megarics.
Euclid of Megara was the founder of this school. His principle was a combination of Socraticism with Eleaticism. Virtue is knowledge, but knowledge of what? It is here that the Eleatic influence became visible. With Parmenides, the Megarics believed in the One Absolute Being. All multiplicity, all motion, are illusory. [{163}] the world of sense has in it no true reality. Only Being is. If virtue is knowledge, therefore, it can only be the knowledge of this Being. If the essential concept of Socrates was the Good and the essential concept of Parmenides Being, Euclid now combined the two. The Good is identified with Being. Being, the One, God, the Good, divinity, are merely different names for one and the same thing. Becoming, the many, Evil, are the names of its opposite, not-being, Multiplicity is thus identified with evil, and both are declared illusory. Evil has no real existence. The Good alone truly is. The various virtues, as benevolence, temperance, prudence, are merely different names for the one virtue, knowledge of Being.
Zeno, the Eleatic, had shown that multiplicity and motion are not only unreal but even impossible, since they are self-contradictory. The Megarics appropriated this idea, together with the dialectic of Zeno, and concluded that since not-being is impossible, Being includes all possibility. Whatever is possible is also actual. There is no such thing as a possible something, which yet does not exist.
