Whenever individuals come to self-consciousness, and have the leisure and security which were enjoyed in many Greek cities of this time as the result of improved social and economic conditions, men find not only the opportunity but also the occasion for reflection. This was the case in our period. Men began to think and question about themselves and the world around them, to reflect not only concerning the political and social world in which they lived, to ask what their place in it was, but also to inquire still deeper into the meaning of things. They debated with themselves questions relating to the gods, the nature and justice of their rule; and most significant for our present interest they began to ask whence men came and whither they were going. One great monument of this period is Hesiod’s “Works and Days,” of which I spoke in my last lecture. It is also important to remember that the seventh and sixth centuries were the age of the so-called Seven Wise Men, to whom were assigned many moral precepts which became revered proverbs in Greece. These sayings, no less than the works of Hesiod and the Gnomic Poets, bear witness to an age of increasing reflection. In the seventh century Ionia controlled the trade between Asia and Europe. Its chief center was Miletus. Here in the first half of the sixth century before our era began Greek philosophy, with Thales, Anaximander, and Anaximenes as the leaders. The modest task which they set themselves was nothing less than the solution of the universe. Their philosophic views are of no special interest to us now; but it is a fact of supreme importance that here for the first time in Greece appeared men whose reflection had made them bold enough to wrestle with the whole problem of nature including man, and to propose solutions entirely at variance with the traditional views. This philosophic development was one result of the factors which we have been considering—factors which produced also new ethical and religious movements that do concern us directly.
