Rawls' remarks about natural endowments provoked an often-referred response by Robert Nozick. Nozick claimed that to treat peoples' natural talents as collective assets is to contradict the very basis of the deontological liberalism Rawls wishes to defend, i.e. respect for the individual and the distinction between persons. Nozick argued that Rawls' suggestion that not only natural talents but also virtues of character are undeserved aspects of ourselves for which we cannot take credit, "can succeed in blocking the introduction of a person's autonomous choices and actions (and their results) only by attributing everything noteworthy about the person completely to certain sorts of 'external' factors. So denigrating a person's autonomy and prime responsibility for his actions is a risky line to take for a theory that otherwise wishes to buttress the dignity and self-respect of autonomous beings."
