Book excerpt: This book argues that Aristotle used "the most traditional Greek ideas about the gods" to develop and defend his physical, metaphysical, and ethical teachings. This revolutionary thesis stands in stark contrast to studies of Aristotle's texts that normally portray him as a "natural theologian" using rational tools to elaborate his own conception of God or the gods. Bodeus argues that Aristotle is more closely aligned with popular Greek religion than is usually thought, and attention to the ethical and political writings reveals more about Aristotle's resources for conceiving the gods than study of his theoretical works.
