Single Idea 17589

[filed under theme 9. Objects / E. Objects over Time / 9. Ship of Theseus ]

Full Idea

If you have rejected the Principle of the Transitivity of (vague) Identity, it is hard to see how the problem of the Ship of Theseus could arise.

Gist of Idea

If you reject transitivity of vague identity, there is no Ship of Theseus problem

A Reaction

I think this may well be the best solution to the whole problem

Idea 17588 We should talk of the transitivity of 'identity', and of 'definite identity' [Inwagen]

There is no reason to think that mere existence is a valuable thing [Inwagen]
The persistence of artifacts always covertly involves intelligent beings [Inwagen]

Mereology is 'nihilistic' (just atoms) or 'universal' (no restrictions on what is 'whole') [Inwagen, by Varzi]
