 Finally, the teleological theorist must account for the connection between intentions with which one acts and psychological states of belief and desire. Why does it follow from the fact that one intends, of what one is doing, that it promote or constitute one’s doing A that one wants to do A and that one believes, of what one is doing, that it is a means to that end? These implications make sense if intention is a species of desire that interacts with means-end belief when one does A with the intention of doing B. They are more difficult to explain if intention-with-which is the basic material from which intention and intentional action are built. (This argument is developed at greater length in Setiya 2011, pp. 146–9.)
