[catalogued under 9. Objects / E. Objects over Time / 3. Three-Dimensionalism]

Full Idea

Some might even regard inconsistency with time travel as an advantage of three-dimensionalism, as a vindication of a prior belief that time travel is impossible! I see no merit in these claims.

Gist of Idea

Some might say that its inconsistency with time travel is a reason to favour three-dimensionalism

A Reaction

I do! Sider cheerfully says that there are good reasons to believe that time travel is possible, and then use this possibility to support his four-dimensional view, but I personally doubt his assumption. The evidence for time travel is flimsy and obscure.
