Abstract

Thomas Aquinas situates virtues of character in the noncognitive appetite. He also claims that virtues of character provide the ends in practical matters. Since providing proper ends seems to be a cognitive act, it is unclear how virtues of character, qua perfections of the noncognitive appetite, provide ends. After criticizing three approaches to this interpretive challenge, we suggest that Aquinas provides us with a theory of practical identity. We argue that that on Aquinas's view a practical identity is constituted both by a virtuous disposition in the appetitive power and by a rational commitment to proximate ends, a rational commitment that results from acquiring the virtuous disposition. With this account of practical identity in mind, we explain how Aquinas can consistently claim that virtues, qua perfections of the appetite, provide ends.
