  John Stuart Mill (1806–1873) was a follower of Bentham, and, through most of his life, greatly admired Bentham's work even though he disagreed with some of Bentham's claims — particularly on the nature of ‘happiness.’ Bentham, recall, had held that there were no qualitative differences between pleasures, only quantitative ones. This left him open to a variety of criticisms. First, Bentham's Hedonism was too egalitarian. Simple-minded pleasures, sensual pleasures, were just as good, at least intrinsically, than more sophisticated and complex pleasures. The pleasure of drinking a beer in front of the T.V. surely doesn't rate as highly as the pleasure one gets solving a complicated math problem, or reading a poem, or listening to Mozart. Second, Bentham's view that there were no qualitative differences in pleasures also left him open to the complaint that on his view human pleasures were of no more value than animal pleasures and, third, committed him to the corollary that the moral status of animals, tied to their sentience, was the same as that of humans. While harming a puppy and harming a person are both bad, however, most people had the view that harming the person was worse. Mill sought changes to the theory that could accommodate those sorts of intuitions.
