Koslicki's Four-Dimensionalism

1247 Words3 Pages

In his work Four-Dimensionalism: An Ontology of Persistence and Time (2001 as cited in Koslicki, 2003; 107), Sider offers an “argument from vagueness,” which is concerned with the question: “Under what conditions do objects come into and go out of existence,” or “Which arrangements of matter are suitable for objects to come into (and go out of) existence?” (Koslicki, 2003; 112). In his answer which allegedly proves universalism, Sider believes this can be extended to spatiotemporal dimension and hence Four-Dimensionalism. The structure of the essay is as follows: first I will consider the possible solutions to the question posed above. Second, I will reiterate Sider’s argument and how it attempts to answers the question. Thirdly, I will consider the position known as the “intermediate” position, using Koslicki’s criticism to Sider to demonstrate my point. Finally, I will attempt to critique the areas that Koslicki grants Sider in a defense of the nihilistic position. Thus in this essay, I will attempt to evaluate the argument from vagueness for the four-dimensionalist metaphysics of material objects and following Koslicki, argue that the non-temporalized argument does not fare as well as Sider claims. Hence, the dependent temporalized argument fares similarly.
I argue that there are three solutions to the question “Under what conditions do objects come into and go out of existence:
S1: Under all conditions (Sider’s view which is referred to as universalism).
S2: Under some conditions (Intermediate).
S3: Under no conditions (Nihilism).
The argument posited by Sider (S1) can be seen as an argument by elimination, where the premises if accepted, reject the possibility of S2 and S3. As such, the argument suffers from whether the re...

...iticisms can be applied (120). Koslicki does consider whether or not Sider’s argument entails four-dimensionalism, and comes to the conclusion that it does not since a three-dimensionalist can accept the conclusion, but remain a three-dimensionalist (121-122). A similar argument cannot be made for nihilist since fusion is done away, although one could make the argument of a simple at each particular time, rather than an object.
As such, I believe that I have provided potential alternatives to the question that the argument from vagueness attempts to solve. While the arguments that I have provided for the alternatives are prone to errors, the goal is to show that it is possible to entertain such alternatives as opposed to accepting universalism, and hence four-dimensionalism. As the non-temporal argument suffers from this weakness, so too does the temporal one.
