This book presents a study of two discussions contained in Porphyry's De Abstinentia. Both of them deal with an often forgotten aspect of antiquity: vegetarianism. The author discusses the connections between the fragments Against the Vegetarians and On Piety and shows how Porphyry, in an open debate with the Stoics, develops a spatial terminology to present his own ethics.
