Abstract

According to a dominant assumption the truth of instrumental thoughts—thoughts in which one action is identified as a means to another—are not affected by agents’ normative conceptions of their ends. Agents could in principle grasp these thoughts, and thereby the correct means to their ends, without consulting any conception they may have as to the pursuit-worthiness of those ends. I argue this assumption (the ‘Theoretical Conception’) prevents us from explaining how agents can identify means to their ends. I sketch an alternative account according to which the contents of instrumental thoughts are directly determined by agent's reasons for acting. This is explained by the fact that an agent's reasons for action reveal what they take the good of their ends to be. Ultimately, I argue, agents must have a conception of their final ends as intrinsically good if they are to successfully specify means to them.
