On the Possibility of Four-Dimensional Objects

In this paper I will be examining the possibility of four-dimensional objects on Mark Heller’s view. I will begin by explaining Heller’s “unpleasant alternatives” argument to three-dimensional objects and why he believes these unpleasant alternatives should lead us to accept a view of four-dimensional objects. I will then examine a challenge to Heller’s view based on an earlier argument by Peter van Inwagen. I will show two ways to interpret van Inwagen and will argue that, based on the strong interpretation of van Inwagen, we should reject Heller’s idea that material objects are four-dimensional
