"The theory that all action aims at attaining pleasure for the agent. In a formulation of John Stuart Mill: all actions are determined by pleasure and pain in prospect, pains and pleasures to which we look forward as the consequences of our acts. Mill held that this, as a universal truth, can in no way be maintained.) The classical objections are those of Butler."
