 One immediately odd aspect of Scanlon’s position that ‘well-being’ is an otiose notion in ethics is that he himself seems to have a view on what well-being is. It involves, he believes, among other things, success in one’s rational aims, and personal relations. But Scanlon claims that his view is not a ‘theory of well-being’, since a theory must explain what unifies these different elements, and how they are to be compared. And, he adds, no such theory is ever likely to be available, since such matters depend so much on context.
