Abstract
Psychological experiments show that human behavior is often determined by features of the situation rather than general and persistent character traits of the agent. Therefore, it may seem naive to suppose that someone with a virtuous character will in general act virtuously. This is at least true if a character trait is taken to be a persistent characteristic or property that reliably causes certain behavior. On the basis of the conception of agency developed by Anscombe in Intention, I will argue against the assumption that virtues are such persistent traits. Rather, I will suggest that virtues stand in a conceptual relation to ways of acting in kinds of contexts in the same way in which intentions are not causes of actions but stand in a conceptual relation to them.
