Bentham and Mill on the ‘quality’ of Pleasures

John Stuart Mill and Jeremy Bentham are often said to have held opposed views concerning the way “the value” of different pleasures should be estimated. Mill is accused of being an inconsistent utilitarian because he thought that, when comparing the value of two pleasures, we should not forget to take their “quality” into account.

No Philosophy for Swine: John Stuart Mill on the Quality ...

2011-11-7  I argue that Mill introduced the distinction between quality and quantity of pleasures in order to fend off the then common charge that utilitarianism is ‘a philosophy for swine’ and to accommodate the (still) widespread intuition that the life of a human is better, in the sense of being intrinsically more valuable, than the life of an animal. I argue that in this he fails because
