Change in View offers an entirely original approach to the philosophical study of reasoning by identifying principles of reasoning with principles for revising one's beliefs and intentions and not with principles of logic. This crucial observation leads to a number of important and interesting consequences that impinge on psychology and artificial intelligence as well as on various branches of philosophy, from epistemology to ethics and action theory.

In this paper I advance an alternative to Davidson’s conception of reasons that preserves the spirit of Davidson's account of effective reasons while avoiding a problem posed by a familiar species of intentional action - roughly, action done for its own sake, or what I shall call intrinsically motivated action.

What is it, precisely, that an agent intends when he intends, as we might say, to clean his stove today? What is the content of his intention? In recent years, Gilbert Harman and John Searle have maintained that all intentions are self-referential -- that is, that an adequate expression of the content of any intention makes essential reference to the intention whose content is being expressed. I shall call this the self-referentiality thesis (SRT). Harman, in his paper 'Practical Reasoning', argues (...) that "the intention to do A is the intention that, because of that very intention, one will do A". Searle, in his book, Intentionality, contends similarly that the "Intentional content" of an agent's "prior intention" to A identifies that very intention as a cause of the agent's (prospective) A-ing. In Sections 1-3 below, I show that the main arguments for the SRT are unsuccessful and that the thesis is problematic. In Section 4, I sketch an alternative account of the contents of intentions.

My goal is to define intending. I defend the view that believing and desiring something are necessary for intending it. They are not sufficient, however, for some things we both expect and want (e.g., the sun to rise tomorrow) are unintendable. Restricting the objects of intention to our own future actions is unwarranted and unhelpful. Rather, the belief involved in intending must be based on the desire in a certain way. En route, I argue that expected but unwanted consequences are (...) not intended, examine the two senses of "desire," distinguish intending from being willing, and relate intending to a variety of other propositional at? titudes.
