Nunc pro tunc : The Problem of Retroactive Enactments

In this paper, I present a problem for the realist with respect to the institutional sphere, and suggest a solution. Roughly, the problem lies in a contradiction that arises as soon as institutional contexts are allowed to influence the institutional profile of objects and events not only in the present, but also in the past. If such Bretroactive enactments^ are effective, in order to avoid contradiction the realist seems to have to accept the unpleasant conclusion that institutions can create a past that has never been present. I will defend a solution which involves a distinction between temporal and atemporal types of institutional kinds that has, I maintain, independent interest.
