Will and Utilitarianism

According to Utilitarianism, the value of an act is determined by its consequences, specifically the subsequent pleasure and pain that it causes. As is widely recognized, the prime target of this Consequentialism is Kantianism, for which the value of an act is determined by the antecedents that motivate it. Less appreciated is that Utilitarianism precludes the possibility that Will, i. e. the performance itself of the act, can be a bearer of value. One problem that that preclusion presents to the doctrine is that the performance itself can be pleasurable. Furthermore, even if that pleasure were to be classified as a 'consequence' of the performance, it still does not take into account how that pleasure can be a function of some antecedents of the performance--e. g. to what extent the performance is innovative in the biography of the performer, whether or not it is an accomplishment of what was initially intended, etc. Hence, Utilitarianism does not, and, apparently, cannot account for at least some of the pleasure involved in the performance of an act.
