Early Greek Philosophy

This is a comprehensive look at the development of Ancient Greek philosophy back in antiquity. From the intro: "IT was not till the traditional view of the world and the customary rules of life had broken down, that the Greeks began to feel the needs which philosophies of nature and of conduct seek to satisfy. Nor were those needs felt all at once. The ancestral maxims of conduct were not seriously questioned till the old view of nature had passed away; and, for this reason, the earliest philosophers busied themselves mainly with speculations about the world around them. In due season, Logic was called into being to meet a fresh want. The pursuit of cosmological inquiry had brought to light a wide divergence between science and common sense, which was itself a problem that demanded solution, and moreover constrained philosophers to study the means of defending their paradoxes against the prejudices of the unscientific. Later still, the prevailing interest in logical matters raised the question of the origin and validity of knowledge; while, about the same time, the break-down of traditional morality gave rise to Ethics. The period which precedes the rise of Logic and Ethics has thus a distinctive character of its own, and may fitly be treated apart."
