 This proposition that “pleasure alone is good as an end,” the fundamental proposition of Ethical Hedonism [is] in Professor Sidgwick’s language, … an object of intuition. I shall try to shew you why my intuition denies it, just as his intuition affirms it. It may always be true notwithstanding; neither intuition can prove whether it is true or not; I am bound to be satisfied, if I can “present considerations capable of determining the intellect” to reject it. (PE: §45)
