The key argument against utilitarianism in all of moral subjectivism, nor that it cannot provide an adequate measure of utility, nor do even that such measurements not adequately take into account the differences between people. Its most problematic assumption is its inherent welfarism that is, the belief that only social utility matters. It is this problem that leads to all the arguments covered earlier in the chapter about how utilitarianism can apparently justify the oppression of minorities, terrible personal injustices and a wide variety of unsavoury social outcomes when not countered by other ethical discourses. It is to one of these discourses that we now turn, that of human rights.
