Socrates, (470–399 BC) being a class unto himself, occupies a unique position in the history of Greek philosophy which fails to mention anyone other than him to belong to that class. There must have been prophets before and after him but of them we can only infer from some oblique references by Socrates himself. For instance, he is known to have said that he is not the only one from God who has been the recipient of revelation; there have been great men before who did the same to serve the cause of goodness. Again, he warns Athenians not to put him to death otherwise they would never see the like of him again, except if God so desires to teach the right path to the Athenians by sending someone else.
This chapter is largely devoted to Socrates and what he stood for, because he manifests a perfect balance of revelation and rationality; but it is impossible not to mention Plato and Aristotle when one talks of Greek philosophy. It is indeed they who pioneered a new mode which has become almost eternal, but they certainly owed their greatness to their revered master.
It was Socrates who had introduced into philosophical discussions of the time, the elements of knowledge, truth and rationality with emphasis so powerful that some biographers describe him as having brought high-flown ethereal philosophies from the heavens down to earth. We believe that the converse is true; the philosophical babble of the sophists before him were the acts of earthly men. It is knowledge, truth and rationality which lift human thoughts to sublime loftiness. That is why though Plato and Aristotle left a most profound and rich heritage for us concerning all philosophical discussions, there is nothing like the lasting noble influence of Socratic integrity which went largely into the making of Plato and Aristotle. The philosophies of Plato and Aristotle are but briefly dealt with, just by way of introduction.
