Single Idea 16199

[filed under theme 9. Objects / E. Objects over Time / 4. Four-Dimensionalism ]

Full Idea

The mass of an object is the sum of its nonoverlapping parts. Analogy would suggest that a persisting banana has, atemporally speaking, a mass that is the sum of all the masses of the 100g temporal parts, a worryingly large figure.

Gist of Idea

If an object is the sum of all of its temporal parts, its mass is staggeringly large!

A Reaction

This is an objection to the Perdurance view that an object is the sum of all of its temporal parts. Their duration tends towards instantaneous, so the aggregate mass tends towards infinity. She says they should deny atemporal mass.
