1. Anarchy, State, and Utopia is routinely characterized as libertarian, an epithet which suggests that liberty enjoys unrivalled pride of place in Nozick's political philosophy. But that suggestion is at best misleading. For the primary commitment of his philosophy is not to liberty but to the thesis of self-ownership, which says that each person is the morally rightful owner of his own person and powers, and, consequently, that each is free (morally speaking) to use those powers as he wishes, provided that he does not deploy them aggressively against others. ‘Libertarianism’ affirms not freedom as such, but freedom of a certain type, whose shape is delineated by the thesis of self-ownership.

In so designating what is central and what is derivative in Nozick, I am denying that he thinks that freedom comes first and that people qualify as self-owners because lack of self-ownership means lack of freedom.
