Presentism and the Problem of Singular Propositions about Non-Present Objects – Limitations of a Proposed Solution

In “A Defense of Presentism ”, Ned Markosian addresses the problem of singular propositions about non-present objects. The proposed solution uses a paraphrasing strategy that differentiates between two kinds of meaning in declarative sentences, and also distinguishes between two truth-conditions for singular propositions. The solution, however, is unsatisfactory. I demonstrate that the both truth-conditions suffer from the same problems in spite of the examples used to support the claim that one is a proper treatment for singular propositions. Part of the difficulty is in the limited expressivity of logical formalisms, a limitation not unique to the philosophy of time, but which calls for greater attention
