It is my view that one essential difference between persons and other creatures is to be found in the structure of a person's will. Besides wanting and choosing and being moved to do this or that, men may also want to have certain desires and motives. They are capable of wanting to be different, in their preferences and purposes, from what they are. Many animals appear to have the capacity for what I shall call "first-order desires" or "desires of the (...) first order," which are simply desires to do or not to do one thing or another. No animal other than man, however, appears to have the capacity for reflective self-evaluation that is manifested in the formation of second-order desires. (shrink)

The first part of the paper focuses on the role played in thought and action by possession of the first‐person concept. It is argued that only one who possesses the I concept is in a position to fully articulate certain fundamental, a priori aspects of the concept of reason. A full understanding of the concept of reason requires being inclined to be affected or immediately motivated by reasons—to form, change or confirm beliefs or other attitudes in accordance with them—when those (...) reasons apply to one's own attitudes. The cases where rational evaluations of acts and attitudes rationally motivate immediate implementation of the evaluations to shape the acts and attitudes are distinguished from cases where they do not, by the use of the first‐person concept to mark those acts and attitudes as one's own. The second part of the paper examines asymmetries between self‐knowledge and knowledge of other minds. The usual view that self‐knowledge has an immediate and a priori warrant, whereas knowledge of others’ minds rests on observation and inference is disputed. A sketch is given of knowledge of other minds that can be non‐inferential and can rest on an intellectual, non‐perceptual entitlement. When one seemingly understands an utterance in interlocution, one is a priori prima facie entitled to suppose that it comes from a rational source, and because knowledge of other minds can be immediate and epistemically grounded in intellectual, non‐empirical entitlements, it is distinguished from self‐knowledge not by being necessarily inferential or by being necessarily grounded in perception, but by being in some known contrast with thought known as one's own.
