Chapter III. Aristocles on the Philosophy of Plato

[ARISTOCLES] [1] ‘IF any man ever yet taught a genuine and complete system of philosophy, it was Plato. For the followers of Thales were constantly engaged in the study of Nature: and the school of Pythagoras wrapped all things in mystery: and Xenophanes and his followers, by stirring contentious discussions, caused the philosophers much dizziness, but yet gave them no help.

‘And not least did Socrates, exactly according to the proverb, add fire to fire, as Plato himself said. For being a man of great genius, and clever in raising questions upon any and every matter, he brought moral and political speculations into philosophy, and moreover was the first who attempted to define the theory of the Ideas: but while still stirring up every kind of discussion, and inquiring about all subjects, he died too early a death.

‘Others took certain separate parts and spent their time upon these, some on Medicine, others on the Mathematical Sciences, and some on the poets and Music. Most of them, however, were charmed with the powers of language, and of these some called themselves rhetoricians and others dialecticians.

‘In fact the successors of Socrates were of all different kinds, and opposed to each other in their opinions. For some sang the praises of cynical habits, and humility, and insensibility; but others, on the contrary, of pleasures. And some used to boast of knowing all things, and others of knowing absolutely nothing.

‘Further some used to roll themselves about in public and in the sight of all men, associating with the common people, while others on the contrary could never be approached nor accosted.

‘Plato however, though he perceived that the science of things divine and human was one and the same, was the first to make a distinction, asserting that there was one kind of study concerned with the nature of the universe, and another concerned with human affairs, and a third with dialectic.

‘But he maintained that we could not take a clear view of human affairs, unless the divine were previously discerned: for just as physicians, when treating any parts of the body, attend first to the state of the whole, so the man who is to take a clear view of things here on earth must first know the nature of the universe; and man, he said, was a part of the world; and good was of two kinds, our own good and that of the whole, and the good of the whole was the more important, because the other was for its sake.

‘Now Aristoxenus the Musician says that this argument comes from the Indians: for a certain man of that nation fell in with Socrates at Athens, and presently asked him, what he was doing in philosophy: and when he said, that he was studying human life, the Indian laughed at him, and said that no one could comprehend things human, if he were ignorant of things divine.

‘Whether this, however, is true no one could assert positively: but Plato at all events distinguished the philosophy of the universe, and that of civil polity, and also that of dialectic.’

Such being the philosophy of Plato, it is time to examine also that of the Hebrews, who had studied philosophy in the like manner long before Plato was born. Accordingly you will find among them also this corresponding tripartite division of Ethical, and Dialectical, and Physical studies, by setting yourself to observe in the following manner:
