According to this approach, the dynamical laws ground the unity of a thing, and the time just as they "occupy" space: by existing as a unity that is spatiotemporally extended. adopting spacetime as the ground of ontological unity is better than using the dynamical laws. you choose to adopt dynamical laws as the ground of unity, an alternative version of presentism ./cache/work_hhkkxl7j2nhdnbgm42732d46ei.pdf ./txt/work_hhkkxl7j2nhdnbgm42732d46ei.txt
