Philosophers Index Abstract

    I argue against the thesis (E) that for every x, for every possible world w, Fx at w only if x exists at w, as follows: Premise 1. Iterated modal1 indexing is redundant; Premise 2. If iterated modal2 indexing is redundant, (E) is false; Conclusion. (E) is false. Premise 1 means that for every x, for every possible world w1, for every possible world w2, Fx at w1 at w2 if and only if Fx at w1. In support of this I cite the meter rod and alpha-transform examples. The crux of the paper consists in arguing for Premise 2. The article presents a new argument against the existence requirement. The article adds that it may appear that in order to be any way at all, a thing must exist. The article adds that E stands for every x, for every possible world w, Fx at w only if x exists at w. the letter. In (E) "F" is used as a schematic letter to be replaced with a one-place predicate. There are two arguments against (E). The first is by analogy. Philosopher Socrates is widely admired now but he does not exist now. So, it is not the case that for every x, for every time t, Fx at t only if x exists at t.
