 We should also note that this passage about earlier theorists speaking of people as having property in themselves is the closest Nozick ever comes to formulating his own position in terms of a doctrine of self-ownership. Contrary to common presentations of Nozick’s doctrine, there is no mention of self-ownership within his Part I discussion of state of nature  theory.[14]  Throughout Part I, Nozick is content to have his readers fill in the content of moral side constraints by drawing on their intuitions that, if there are any moral side constraints, they must include constraints against (unprovoked) killing, assaulting, maiming, enslaving. There is, at most, a hint that all of these constraints can be subsumed under a general constraint against aggression (34). (It seems, however, that aggression itself requires explication on the basis of a prior and independent specification of persons’ rights.)
