Abstract

D. Lewis said that there are three solutions for the problem of temporary intrinsics, namely, relationalism, presentism, and four-dimensionalism. Lewis also argued that the only tenable one is four-dimensionalism. But advocates of the other solutions reject it. Although objection is possible, it seems that Lewis' argument is not enough to show that four-dimensionalism is the best. However, it doesn't mean that four-dimensionalism is not worth considering. For relationalism and presentism are inconsistent. Moreover, relationalism must deny.ordinary talk and presentism doesn't contradict with four-dimensionalism. So it is concluded that four-dimensionalist doesn't have to throw away his position.
