  In addition to considerations in moral psychology, there are also reasons to prefer a pleasure-based theory of desire that stem from the philosophy of mind. Galen Strawson defends a pleasure-based theory on two grounds: first, Strawson holds that being a desire for anything (or being a belief about anything or otherwise exhibiting intentionality) requires consciousness, and pleasure and displeasure are the states of consciousness most closely linked to desire. And second, Strawson holds that it is conceivable that there be creatures who would lack dispositions to act but who would have dispositions to feelings of pleasure and displeasure, and that these creatures would seem to have desires for the things that would please them. These creatures might include actual human beings suffering from neurological injuries removing their dispositions to act, and they might include purely imaginary beings never born with capacities to act, just capacities to feel (Strawson 1994).
