Overall, Gregory provides a thorough introduction to the debates on Presocratic naturalism. He successfully shows that, in many instances, what may seem at first glance to be supernatural was actually carefully integrated into a naturalist conception of the world. His inclusive approach should be particularly invaluable for those who have not yet ventured beyond the confines of the standard philosophical canon.
