Utilitarianism, like most consequentialist moral theories, can be broken down into two broad components: (1) a theory of goodness, and (2) a theory of how the goodness of the outcome of an act relates to that act’s rightness. Utilitarianism says that (1) goodness is constituted by the total summation of the pleasure over pain of all sentient creatures where each creature is given equal consideration, and (2) an act is right if and only if the actual consequences of that act have more goodness than any other alternative. Further, I believe that a theory of goodness can be broken down into two subcomponents: (1a) a theory of individual goodness, and (1b) a theory of how the goodness of individuals relates to the collective goodness (e.g. using some sort of aggregation function). Utilitarianism says that (1a) individual goodness is constituted by the total amount of pleasure and pain for that individual, and (1b) the collective goodness is simply the total summation of every sentient creature’s individual goodness. In this post, I will criticize each of these three components of utilitarianism. These criticisms, I believe, provide sufficient reason to reject utilitarianism.
