INTRODUCTION

Ancient Greek philosophy arose in a culture whose world had always teemed with divinities. “Everything is full of gods, ”said Thales (Aristotle De an. 1.5, 411a8), and the earliest “theories of everything” were mythological panoramas such as Hesiod's Theogony, in which the genealogy of the gods is also a story about the evolution of the universe. Hence when certain Greeks began to think about the physical world in a philosophical way, they were concerning themselves with matters which it was still quite natural to term “divine, ” even in the context of their new scientific approach. Because of this, it is not entirely obvious where one should draw the line between the theology of the early Greek philosophers and their other achievements. But clarity is not served by classifying as “theological” every statement or view of theirs that features concepts of divinity. To theologize is not simply to theorize using such concepts in a non-incidental way. Rather, it is, for instance, to reflect upon the divine nature, or to rest an argument or explanation on the idea of divinity as such, or to discuss the question of the existence of gods, and to speculate on the grounds or causes of theistic belief.
