In this thesis I argue for three central points: spacetime is substantival, spacetime is not composed of points, and a particular form of spatiotemporal monism is true. More detailedly, I argue that the three points are interconnected and that the truth of the first two claims, if established, serves as strong evidence for spatiotemporal monism. Additionally, while I do offer positive argumentation in support of spatiotemporal monism and region theory, I argue that the most compelling evidence in favor of spatiotemporal monism is it stands to potentially help unify metaphysics in virtue of compatibility with related metaphysical theories in a way that point theory cannot. |
