Against Presentism: Two Very Different Types of Objections
Abstract
I argue that the most familiar forms of presentism can be seen, upon reflection, to involve two very different claims. Most arguments against such forms of presentism are directed against one of those claims, and I think that the arguments in question, properly formulated, are sound. In this paper, however, I want to set out an argument directed against the second claim, and to consider the prospects for that type of argument.
My discussion is organized as follows. In section 1, I describe four different forms that presentism can take, which I refer to as extreme presentism, austere, reductive presentism, tensed-facts presentism, and ersatzer presentism. Of these four forms of presentism, only the last two are popular today.
In section 2, I briefly describe the more important types of objections that are standardly advanced against presentism.
Then, in section 3, I argue that the dispute between presentists other than extreme presentists, on the one hand, and non-presentists, on the other, is very different from the dispute between, say, theists and atheists, and that this difference has important implications with regard to the types of objection that can be directed against presentism.
Finally, in section 4, I set out the alternative line of argument against presentism that arises out of that difference.
