Abstract

I have two basic goals in this paper. The one is to suggest that in thinking about objections to presentism, it is useful to structure those objections in a certain way. The second is then to set out, and evaluate, objections to presentism, and to show that presentism is untenable. My discussion is organized as follows. In section 1, I briefly distinguish between two very different varieties of presentism, on only one of which I shall focus here. In section 2, I discuss how presentism is best defined. That discussion is inconclusive, but I am inclined to recommend a different characterization of presentism than is normally offered. Sections 3 through 9 are then concerned with objections to presentism. In section 3, I refer briefly to tenseless objections to all tensed views, including presentism, and to one central objection in particular that I think is very important. But I do not attempt either to answer that objection, or to support it, in this paper. In section 4, I discuss four objections to presentism that seem to me either problematic or unconvincing as they are ordinarily stated. I shall also consider, however, whether some of these objections can be reinstated. In discussing, in section 4, a version of the truthmaker objection set out by David Armstrong, I suggest that, in thinking about objections to presentism, it is best to divide up sentences about the past in a certain way, and my brief statement, in section 5, of what I take to be the crucial objections to presentism, is organized along those lines. In sections 6 and 7, I set out two objections to tensed-facts presentism that are concerned with general propositions about the past that do not involve cross-temporal relations, and that are not expressed by sentences that contain proper names. The first of these objections is concerned with the meaning of statements about the past or about the future; the second is the truthmaker objection. Section 8 is then concerned with objections to tensed-facts presentism that focus upon cross-temporal relations. Here I argue that it is the relation of causation that is crucial. In section 9, I then turn to the question of whether sentences containing names of individuals that no longer exist pose an additional, independent problem for tensed-facts presentism.
