Abstract
According to a common view of human agency, desires determine at least some of the ends that agents set for themselves. In this paper, I argue that this view is false. I show that without reason’s ability to determine the means to an end it is impossible to determine ends. Furthermore, even when an end is determined in light of a desire, only reason can make sense of the distinction between an end and merely a means to that end. In fact, in many cases the end which is determined in light of desires is to remove these desires, rather than to “serve and obey” them. Hence, reason is necessary for determining our ends, and thus explaining the teleological aspect of agency.
