Abstract
My aim in this paper is to show a tension in the nozickian entitlement theory. The tension is between the enforcement of the rectification principle in ideal epistemic conditions and the first two clauses of the theory. In order to do that, I argue that the principle of rectification in the above conditions entails a weird theoretical result: it is better applied under relative ignorance than under ideal conditions, which suggests that Nozick’s theory is too rigid. The underlying point is that Nozick neglects some important aspects concerning the effects of time in property claims. I finish the paper suggesting that we can face this problem in two ways and that both imply costs. The first one is to keep the theory as it was conceived, accepting the objection that it is, in a way, implausible. Or we can change the theory and weaken its purely historical character. And it is not clear how this can be done without raising difficulties.
