 The “many”’s worry about the inadequacy of knowledge to ensure virtuous action suggests that virtuous character includes not only a cognitive element, but also some affective element. Both Plato and Aristotle argue that virtuous character requires a distinctive combination of cognitive and affective elements. In the Republic, Plato divides the soul into three parts and gives to each a different kind of desire (rational, appetitive, or spirited). As types of non-rational desire, appetitive and spirited desires can conflict with our rational desires about what contributes to our overall good, and they will sometimes move us to act in ways we recognize to be against our greater good. When that happens, we are incontinent. To be virtuous, then, we must both understand what contributes to our overall good and have our spirited and appetitive desires educated properly, so that they agree with the guidance provided by the rational part of the soul. Plato describes the education of the non-rational parts of the soul in Books II and III of the Republic. A potentially virtuous person learns when young to love and take pleasure in virtuous actions, but must wait until late in life to develop the understanding that explains why what he loves is good. Once he has learned what the good is, his informed love of the good explains why he acts as he does and why his actions are virtuous.
