 When Nozick asserts that individuals possess pre-political, pre-contractual moral rights against certain things being done to them—even for the sake of ends that are or purport to be socially optimal—he is most obviously ascribing claim-rights to individuals correlative to which are pre-political and pre-contractual moral obligations of each agent not to do certain things to other individuals. Since, all state of nature obligations (that are rights-correlative and, hence, enforceable) are negative, in the state of nature individuals are morally at liberty to engage in any conduct that does not transgress others’ state of nature claim-rights. Thus, Nozick’s opening proclamation of rights affirms for each individual extensive liberty-rights—extensive freedom from obligations, especially positive obligations—that are systematically protected against interference by moral claim-rights. It needs to be mentioned that these moral rights are taken to be people’s baseline rights; they are rights that are subject to contraction or expansion through an individual’s actions and interactions. So, e.g., although each individual has a natural right against all others not to be struck in her nose, each may waive that right by agreeing to take place in a boxing match, and each may acquire a liberty-right to strike the other party to the boxing contract.
