Adam Drozdek 
Greek Philosophers as Theologians [PDF ebook] 
The Divine Arche

Concepts of God presented by Greek philosophers were significantly different from the image of the divine of popular religion and indicate a fairly sophisticated theological reflection from the very inception of Greek philosophy. This book presents a comprehensive history of theological thought of Greek philosophers from the Presocratics to the early Hellenistic period. Concentrating on views concerning the attributes of God and their impact on eschatological and ethical thought, Drozdek explains that theology was of paramount importance for all Greek philosophers even in the absence of purely theological or religious language.
