 It [impartiality] is involved in the very meaning of Utility, or the Greatest-Happiness Principle. That principle is a mere form of words without rational signification, unless one person’s happiness, supposed equal in degree (with the proper allowance made for kind), is counted for exactly as much as another’s. Those conditions being supplied, Bentham’s dictum ‘everybody to count for one, nobody for more than one,’ might be written under the principle of utility as an explanatory commentary. The equal claim of everybody to happiness in the estimation of the moralist and the legislator involves an equal claim to all the means of happiness …. And hence all social inequalities which have ceased to be considered expedient, assume the character not of simple inexpediency, but of injustice. The entire history of social improvement has been a series of transitions, by which one custom or institution after another, from being supposed a primary necessity of social existence, has passed into the rank of universally stigmatized injustice and tyranny. So it has been with the distinctions of slaves and freemen, nobles and serfs, patricians and plebeians; and so it will be, and in part already is, with the aristocracies of colour, race, and sex. (V 36)
