CHAPTER III.
THE ACADEMY AND THE PORCH.

Political changes of the 4th century.

58. Before a hundred years had passed since the death of Socrates, the face of the Greek world had been completely changed. Athens, Lacedaemon, Corinth, Thebes, which had been great powers, had sunk into comparative insignificance; their preeminence was gone, and even of their independence but little remained. Throughout Greece proper the Macedonian was master. But if the old-fashioned politician suffered a bitter disappointment, and the adherents of the old polytheism despaired of the future, there was rich compensation for the young and the hopeful. Petty wars between neighbouring cities, with their wearisome refrain ‘and the men they killed, and the women and children they enslaved[1],’ began to be less common; internal and still more murderous strife between bigoted oligarchs or democrats began to be checked from without. For the enlightened Greek a new world of enterprise had been opened up in the East. Alexander the Great had not only conquered Asia Minor, and established everywhere the Greek language and a Greek bureaucracy; he had opened the way to the far East, and pointed out India and even China as fields for the merchant and the colonizer. His work had been partly frustrated by the disorders that followed his death; but if achievement was thus hindered, hopes were not so quickly extinguished. These new hopes were not likely to be accompanied by any lasting regrets for the disappearance of ancient systems of government now regarded as effete or ridiculous, or of inherited mythologies which were at every point in conflict with the moral sense[2].

East and West.

59. The same historic events which opened the East to Hellenic adventurers also made the way into Europe easy for the Oriental. As the soldier and the administrator travelled eastward, so the merchant and the philosopher pushed his way to the West. Not merely in Persia had ancient superstitions been swept away by reforming zeal; the Jews were now spreading from town to town the enthusiasm of a universalized religion which was ridding itself of bloody sacrifices; and, for the time at least, the humane philosophy of the Buddha was dominant in India, was being preached far and wide by self-sacrificing monks, and was inspiring the policy of great monarchies. We find it hard to picture the clashing of ideals, enthusiasms, and ambitions which was at this time taking place in all the great cities of the old world; but it is certain that in the universal excitement the old distinctions of Greek and barbarian, Jew and Gentile, rich and poor, free and slave, man and woman were everywhere becoming weakened, and community of thought and temperament were beginning to reunite on a new basis individuals who had broken loose from the ties of ancient society.

New schools of philosophy.

60. During this fourth century B.C. the foundations were laid of the four philosophical schools which were destined to vie one with another for the allegiance of the Roman world. The Socratic schools which we have already mentioned, those of the Cynics and Cyrenaics, did not perhaps altogether die out; in particular the Cynic missionaries appear to have been a social force until the second century B.C. But their intellectual basis was too narrow to admit of their effective transplantation to new soil. At the end of the century each gave place to a new school, which preserved the central doctrines of its predecessor. The Socratic paradoxes were handed on from the Cynics to the Stoics; the doctrine that pleasure is the good was accepted by Epicurus. Stoics and Epicureans disputed with a bitterness as yet unequalled, finding themselves just as much opposed upon the subjects of logic and physics, which they introduced anew into popular philosophy, as upon the questions of ethics on which their antipathies were inherited. Between them stood two schools which had meanwhile established themselves. Plato, himself a companion of Socrates, founded the Academy at Athens about 380 B.C.; and if he did not impress his own teaching upon it with absolute fixity, still the school flourished under a succession of leaders, always proud of the fame of its founder, and rendering him at least a nominal allegiance. From the Academy branched off the school of the Peripatetics, founded by Plato’s pupil Aristotle about 350 B.C. After Aristotle’s death this school gravitated towards the Academics, and in later centuries there seemed little difference, if any, between the two. If Stoicism may be called the child of Cynism, it largely drew nourishment from these two schools and their founders. Some account of the teaching of Plato and Aristotle is therefore needed here, partly because of the great importance of both in the general history of philosophy, partly because of their direct influence upon the subject of this book. On account of the much greater prominence of the Academy in the later history we shall often use this term to refer to the general teaching of the two allied schools.

Plato.

61. Of all the companions of Socrates far the most famous is Plato of Athens (427-347 B.C.), the founder of the philosophical association known as the ‘Academy.’ In the general judgment of lovers of Greek letters he stands out not merely as a great master of Attic prose style, but also as the ablest exponent of the true mind of Socrates[3], and the most brilliant light of Greek philosophy[4]. On the first point this judgment stands unchallenged; for delicate and good-natured wit, felicity of illustration and suggestiveness of thought the Platonic dialogues are unrivalled. But it is only in his earlier writings that we can accept Plato as a representative of Socrates; after the death of his master he travelled for many years in Egypt, Lower Italy, and Sicily, and absorbed in particular much of the teaching of the Pythagoreans. The theory of ‘ideas,’ the special characteristic of Plato’s later work, is not strictly Socratic. Neither, we must add, is it of first-rate importance in the history of human thought; from our point of view it lies apart from the main current both of speculation and of practice. It was a still-born theory, not accepted even by Plato’s successors in the control of the Academy[5]. We are therefore very little concerned with the direct teaching of Plato; but all the more readily it should be acknowledged that the Stoics were often indebted to him for help in the treatment of important details, and that the Platonic attitude remained for them a factor of which they needed continuously to take account.
