I’ll start by giving a very brief summary of Sider’s position and will identify some points on which my own position differs from his. I’ll then raise four issues, viz., how to articulate the 3-dimensionalist view, the trade-offs between Ted’s stage view of persistence and endurance with respect to intrinsic properties, the endurantist’s response to the argument from vagueness, and finally more general questions about what’s at stake in the debate. I don’t believe that anything I say raises insurmountable problems for Sider’s view; and in fact, I’m sure he’s in a better position to defend his view more convincingly than I’m able to defend mine. However, there is plenty worth discussing further.
