Handout #4: The Authority of Desire and Perfectionism

STAMPE AND THE PER SE AUTHORITY OF DESIRE

  1. Beliefs and desires are to be distinguished by their different directions of fit to the world: beliefs aim to conform themselves to the world, whereas desires aim to conform the world to them.
  2. Moreover, we should understand belief as aiming at the true and desire as aiming at the good.
  3. But then desire can provide defeasible reason to act, as perceptual belief can provide defeasible reason to believe.
  4. The per se authority of perception implies that one has reason to believe as one perceives even when one has no other reason to trust one's perceptions or knows it to be unreliable (mistaken?).  Reasons to believe can be overridden and need not even be good reasons.
  5. The per se authority of desire implies that one has reason to act as one desires even if one has no other reason to regard the object of one's desire as good or one knows it to be valueless.  Reasons to act can be defeasible and need not be good reasons.
(4) and (5) simply elaborate the implications of (3).  This argument derives the per se authority of desire from the good-dependence of desire.  But one might question (a) whether per se authority follows from the good-dependence of desire and (b) whether desire, as such, is good-dependent.

(a) It's not clear that we ought to accept the authority of perception or desire when there is good reason to doubt that the perception tracks the truth or that the desire tracks the good. For example, it is doubtful that perceiving that the gas gauge registers F provides reason to believe that my tank is full even if I know it is malfunctioning.  The same seems true of the desire to collect lint.  Reasons to believe or act can be defeasible, but what are they if they are not good reason?

(b) Though desires can be good-dependent, they do not seem to be necessarily good-dependent.  (i) The desires might be unwelcome (e.g. the self-loathing drug addict or pedophile), (ii) desire might be produced by sub-rational processes (e.g. hypnosis or suggestion), and (iii) brutes and small children appear to have desires without belief in the value of their objects.  How can we bo so sure?  (2) is an independent premise; it does not follow from (1).  In fact, we can appeal to (1) to argue against (2).  States with the functional profile of desires can, but need not, be based upon beliefs about the value of their objects.
