of the universe, and thus to pass from ethics to metaphysics.
Others again, whose demand for knowledge was more easily
satisfied, and who were more impressed with the positive and
practical side of the master’s teaching, made the quest a much
simpler affair. They took the Good as already known, and held
philosophy to consist in the steady application of this knowledge
to conduct. Among these were Antisthenes the Cynic and
Aristippus of Cyrene. It is by their recognition of the duty of
living consistently by theory instead of mere impulse or custom,
their sense of the new value given to life through this rationalization,
and their effort to maintain the easy, calm, unwavering
firmness of the Socratic temper, that we recognize both Antisthenes
and Aristippus as “Socratic men,” in spite of the completeness
with which they divided their master’s positive doctrine
into systems diametrically opposed. Of their contrasted principles
we may perhaps say that, while Aristippus took the most
obvious logical step for reducing the teaching of Socrates to clear
dogmatic unity, Antisthenes certainly drew the most natural
inference from the Socratic life.
Aristippus (see Cyrenaics) argued that, if all that is beautiful or admirable in conduct has this quality as being useful, i.e. productive of some further good; if virtuous action is essentially action done with insight, or rational apprehension of the act as a means to this good, this Aristippus. good must be pleasure. Bodily pleasures and pains Aristippus held to be the keenest, though he does not seem to have maintained this on any materialistic theory, as he admitted the existence of purely mental pleasures, such as joy in the prosperity of one’s native land. He fully recognized that his good was capable of being realized only in successive parts, and gave even exaggerated emphasis to the rule of seeking the pleasure of the moment, and not troubling oneself about a dubious future. It was in the calm, resolute, skilful culling of such pleasures as circumstances afforded from moment to moment, undisturbed by passion, prejudices or superstition, that he conceived the quality of wisdom to be exhibited; and tradition represents him as realizing this ideal to an impressive degree. Among the prejudices from which the wise man was free he included all regard to customary morality beyond what was due to the actual penalties attached to its violation; though he held, with Socrates, that these penalties actually render conformity reasonable. Thus early in the history of ethical theory appeared the most thoroughgoing exposition of hedonism.
Far otherwise was the Socratic spirit understood by Antisthenes and the Cynics (q.v.). They equally held that no speculative research was needed for the discovery of good and virtue, and maintained that the Socratic wisdom was exhibited, not in the skilful pursuit, but in the rational The Cynics. disregard of pleasure,—in the clear apprehension of the intrinsic worthlessness of this and most other objects of men’s ordinary desires and aims. Pleasure, indeed, Antisthenes declared roundly to be an evil; “Better madness than a surrender to pleasure.” He did not overlook the need of supplementing merely intellectual insight by “Socratic force of soul”; but it seemed to him that, by insight and self-mastery combined, an absolute spiritual independence might be attained which left nothing wanting for perfect well-being (see also Diogenes). For as for poverty, painful toil, disrepute, and such evils as men dread most, these, he argued, were positively useful as means of progress in spiritual freedom and virtue. There is, however, in the Cynic notion of wisdom, no positive criterion beyond the mere negation of irrational desires and prejudices. We saw that Socrates, while not claiming to have found the abstract theory of good or wise conduct, practically understood by it the faithful performance of customary duties, maintaining always that his own happiness was therewith bound up. The Cynics more boldly discarded both pleasure and mere custom as alike irrational; but in so doing they left the freed reason with no definite aim but its own freedom. It is absurd, as Plato urged, to say that knowledge is the good, and then when asked “knowledge of what?” to have no positive reply but “of the good”; but the Cynics do not seem to have made any serious effort to escape from this absurdity.
The ultimate views of these two Socratic schools we shall have to notice presently when we come to the post-Aristotelian schools. We must now proceed to trace the fuller development of the Socratic theory in the hands of Plato and Aristotle.
The ethics of Plato cannot properly be treated as a finished result, but rather as a continual movement from the position of Socrates towards the more complete, articulate system of Aristotle; except that there are ascetic and mystical suggestions in some parts of Plato’s teaching which Plato. find no counterpart in Aristotle, and in fact disappear from Greek philosophy soon after Plato’s death until they are revived and fantastically developed in Neopythagoreanism and Neoplatonism. The first stage at which we can distinguish Plato’s ethical view from that of Socrates is presented in the Protagoras, where he makes a serious, though clearly tentative effort to define the object of that knowledge which he with his master regards as the essence of all virtue. Such knowledge, he here maintains, is really mensuration of pleasures and pains, whereby the wise man avoids those mistaken under-estimates of future feelings in comparison with present which we commonly call “yielding to fear or desire.” This hedonism has perplexed Plato’s readers needlessly (as we have said in speaking of the Cyrenaics), inasmuch as hedonism is the most obvious corollary of the Socratic doctrine that the different common notions of good—the beautiful, the pleasant and the useful—were to be somehow interpreted by each other. By Plato, however, this conclusion could have been held only before he had accomplished the movement of thought by which he carried the Socratic method beyond the range of human conduct and developed it into a metaphysical system.
This movement may be expressed thus. “If we know,” said Socrates, “what justice is, we can give an account or definition of it”; true knowledge must be knowledge of the general fact, common to all the individual cases to which we apply our general notion. But this must be no less true of other objects of thought and discourse; the same relation of general notions to particular examples extends through the whole physical universe; we can think and talk of it only by means of such notions. True or scientific knowledge then must be general knowledge, relating, not to individuals primarily, but to the general facts or qualities which individuals exemplify; in fact, our notion of an individual, when examined, is found to be an aggregate of such general qualities. But, again, the object of true knowledge must be what really exists; hence the reality of the universe must lie in general facts or relations, and not in the individuals that exemplify them.
So far the steps are plain enough; but we do not yet see how this logical Realism (as it was afterwards called) comes to have the essentially ethical character that especially interests us in Platonism. Plato’s philosophy is now concerned with the whole universe of being; yet the ultimate object of his philosophic contemplation is still “the good,” now conceived as the ultimate ground of all being and knowledge. That is, the essence of the universe is identified with its end,—the “formal” with the “final” cause of things, to use the later Aristotelian phraseology. How comes this about?
Perhaps we may best explain this by recurring to the original application of the Socratic method to human affairs. Since all rational activity is for some end, the different arts or functions of human industry are naturally defined by a statement of their ends or uses; and similarly, in giving an account of the different artists and functionaries, we necessarily state their end, “what they are good for.” In a society well ordered on Socratic principles, every human being would be put to some use; the essence of his life would consist in doing what he was good for (his proper ἔργον). But again, it is easy to extend this view throughout the whole region of organized life; an eye that does not attain its end by seeing is without the essence of an eye. In short, we may say of all organs and instruments that they are what we think them in proportion as they fulfil their function and attain their end. If, then, we conceive the whole universe organically, as a complex arrangement of means to ends, we shall
