Original and engaging, this exploration of early Western philosophy traces the religious roots of science and systematic speculation. Author F. M. Cornford, a distinguished historian of ancient philosophy, combines deep classical scholarship with anthropological and sociological insights to examine the mythic precursors of enduring metaphysical concepts--such as destiny, God, the soul, substance, nature, and immortality. Cornford illustrates the rise of a new spirit of rational inquiry from traditional beliefs, demonstrating that philosophy’s modes of clear definition and explicit statement were already implicit in the unreasoned intuitions of mythology.
