Abstract

It is well known that Socrates sketches, through his similes of the sun, line, and cave, an account of the form of the good in the middle books of the Republic and that this conception of the good relies heavily on his theory of forms. What is less well-noted is that Socrates presents a distinct account of goodness - a functional account - in Republic I. In numerous influential articles, Gerasimos Santas has presented an interpretation of Plato's two theories of goodness and their relationship to one another. In this discussion, I argue that Santas's account cannot be correct. My critique has implications with regard to the issue of the relationship between form and function in Plato's metaphysics of value.
