Single Idea 16206
[filed under theme 9. Objects / E. Objects over Time / 5. Temporal Parts
]
Full Idea
To account for change, stages and temporal parts must be as fine-grained as change: a material thing must have as many stages or parts as it is in incompatible states during its lifetime.
Gist of Idea
Stages must be as fine-grained in length as change itself, so any change is a new stage

A Reaction
There seems to be a dilemma for stages here, of being so fat that they are divisible and change, or so thin that they barely exist. Lose-lose, I'd say.
