Abstract

Self-interest theories hold that rationality requires one always to choose what is best for oneself. Where these theories differ is in their accounts of what is best for one. Hedonism is a typical self-interest theory, distinguished from other versions by the claim that what is best for one is what gives one the greatest net balance of pleasure over pain. Gómez-Lobo thinks that Socrates is a self-interest theorist: Socrates believes that “a choice is rational if and only if it is a choice of what is best for the agent”. Gómez-Lobo also thinks that Socrates holds that “something is good for an agent if and only if it is morally right” ; this distinguishes his theory from hedonism and other self-interest theories. Finally, Gómez-Lobo thinks that Plato defends Socrates’ in arguing at Gorgias 506c5-507a3 that “a being is good if and only if it has the order proper to it”: follows from and other Socratic principles. These three claims constitute the “foundations” of Socratic ethics mentioned in Gómez-Lobo’s title.
