Single Idea 16203
[filed under theme 9. Objects / E. Objects over Time / 5. Temporal Parts
]
Full Idea
The first worry for Stage Theory is that many present stages are bananas, and many stages tomorrow are bananas, but this seems to omit the important fact that some of those stages are intimately linked, that certain stages are the same banana.
Gist of Idea
Stage Theory seems to miss out the link between stages of the same object
Source
Katherine Hawley (How Things Persist [2001], 2.3)
Book Ref
Hawley,Katherine: 'How Things Persist' [OUP 2004], p.46
A Reaction
Hawley has a theory to do with external relations, which I didn't find very persuasive. Just to say stages have a 'relation' seems too abstract. Stages of disparate things can also have 'relations', but presumably the wrong sort.
