Presentism, eternalism, and growing-blockism are theories or models of what the temporal and ontic structure of the world is, or could be. i shall set aside the question of whether whichever theory is true is necessarily true or only contingently true. since defenders of each of these views at the very least think that they are competing views about the way our world is in fact, i focus discussion on this aspect of the dialectic.Presentism, eternalism, and growing-blockism are, in part, theories about what exists. "Exists" is used in ordinary English in a number of ways. To understand what is at issue between these three views we need to understand what each view intends when it makes claims about what exists. suppose i stand in my kitchen and utter the following three claims:A. There is no santa Claus. B. There is no beer. C. There are no dinosaurs.When i utter (B) in my kitchen, what i say is true. That is because it is natural to understand me as claiming that there is no beer in my kitchen. since there is beer at the local shop, the claim that there is no beer at all anywhere is false. That is, the claim "there is no beer" is false if we do not relativize the claim to some particular domain, like my kitchen, in which there is no beer.When i utter (A) this is also true. 1 But a natural reading of my utterance of (A) in my kitchen is not that that there is no santa Claus in my kitchen, though that is true, but that there is no santa Claus anywhere: no santa simpliciter, as we put it. The difference between (A) and (B) is that a natural reading of (B) tacitly restricts the domain 21 A Companion to the Philosophy of Time, First Edition. Edited by Heather Dyke and Adrian Bardon.
