Belief Retention: A Fregean Account

Concerning cases involving temporal indexicals Kaplan has argued that Fregean thoughts cannot be the bearers of cognitive significance due to the alleged fact that one can think the same thought from one occasion to the next without realizing this—thus linking the issue of cognitive significance to that of belief retention. Kaplan comes up with his own version of the Fregean strategy for accounting for belief retention that does not face this kind of a problem; but he finds it deficient because it leads us to implausibly deny that one who is lost in time retains the beliefs one held before this occurred. I take issue with Kaplan though in conformity with his plausible demands about belief retention and argue that a situation does not arise in which one can fail to realize that one is thinking the same thought from one occasion to the next. I also argue that thoughts are the bearers of cognitive significance as well as explanatory of belief retention
