Abstract

In this study, we will examine two important issues that we encountered in the debates such as the metaphysics of temporal parts in the context of Sider’s arguments about four-dimensionalism. First one of these issues is the difference between perduring objects and three-dimensional objects; and the second one is that the problem of temporal parts. Likewise, we will try to explain what temporal extention and perdurantism is and also, we will try to expose difference between four-dimensional and three-dimesional object.
