““To have understood the polymorphous character of pleasure and happiness is of course to have rendered those concepts useless for utilitarian purposes; if the prospect of his or her own future pleasure or happiness cannot for reasons which I have suggested provide criteria for solving the problems of action in the case of each individual, it follows that the notion of the greatest happiness of the greatest number is a notion without any clear content at all. It is indeed a pseudo-concept available for a variety of ideological uses, but no more than that.””
