 On the other hand, it would certainly be unfair to Nozick to insist that there be one or a few core foundationalist arguments on which all of the rest of his doctrine firmly rests. It is clear that Nozick thinks that the coherence that obtains among the stances he develops within ASU enhances the plausibility of each of those stances. For instance, while his historical entitlement theory of justice in holdings is largely grounded in his critique of alternative conceptions of economic justice, Nozick takes the coherence between this theory with his affirmation of basic moral side constraints to increase the plausibility of his doctrine as a whole. Similarly, Nozick takes the coherence of his rights based defense of the minimal state in Part I of ASU with his less moralistic defense of the minimal state as a framework for utopia in Part III to enhance the overall case for the minimal  state.[15]
