I thank the members of the Law and Philosophy Discussion Group in Los Angeles and those who attended a talk sponsored by the philosophy department at New York University, where I presented earlier versions of this paper. I would also like to thank G. A. Cohen, Stephen Munzer, Seana Shiffrin, Peter Vallentyne, Andrew Williams, and the editors of Philosophy & Public Affairs, who read and provided written commentary on earlier drafts.

In this book G. A. Cohen examines the libertarian principle of self-ownership, which says that each person belongs to himself and therefore owes no service or product to anyone else. This principle is used to defend capitalist inequality, which is said to reflect each person's freedom to do as as he wishes with himself. The author argues that self-ownership cannot deliver the freedom it promises to secure, thereby undermining the idea that lovers of freedom should embrace capitalism and the inequality (...) that comes with it. He goes on to show that the standard Marxist condemnation of exploitation implies an endorsement of self-ownership, since, in the Marxist conception, the employer steals from the worker what should belong to her, because she produced it. Thereby a deeply inegalitarian notion has penetrated what is in aspiration an egalitarian theory. Purging that notion from socialist thought, he argues, enables construction of a more consistent egalitarianism. (shrink)

Libertarianism holds that agents initially fully own themselves and have moral powers to acquire property rights in external things under certain conditions. It is normally advocated as a theory of justice in the sense of the duties that we owe each other. So understood, it is silent about any impersonal duties (i.e., duties owed to no one) that we may have.
