This paper considers on what basis justice may require that people be treated as equals. It begins with an examination of the argument that people are to be treated as equals because they are equals, and suggests reasons for thinking that such an argument is unlikely to succeed. The remainder of the paper considers, and tries to make plausible, the argument that justice requires people be treated as equals because they are individuals. Thus the paper offers some support for the view that the proper foundation of egalitarianism is individualism.
