Single Idea 12298

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

Full Idea

In order to have genuine motion, rather than mere variation in position, it is necessary that the object should be 'entirely present' at each moment of the change. Thus without entire presence, or existence, genuine motion will not be possible.

Gist of Idea

Genuine motion, rather than variation of position, requires the 'entire presence' of the object

A Reaction

See Idea 4786 for a rival view of motion. Of course, who says we have to have Kit Fine's 'genuine' motion, if some sort of ersatz motion still gets you to work in the morning?
