Single Idea 14729
[filed under theme 9. Objects / E. Objects over Time / 4. Four-Dimensionalism
]
Full Idea
Four-dimensionalism may be formulated as the claim that, necessarily, each spatiotemporal object has a temporal part at every moment at which it exists.
Gist of Idea
4D says each spatiotemporal object must have a temporal part at every moment at which it exists

A Reaction
If there were tiny quantum gaps between temporal parts, that would presumably ruin the story. On this view an object has to be a 'worm', to be the thing which has the parts.
