17588 | We should talk of the transitivity of 'identity', and of 'definite identity' [Inwagen] |
Full Idea: In some contexts, the principle of 'the transitivity of identity' should be called 'the transitivity of definite identity'. | |
From: Peter van Inwagen (Material Beings [1990], 18) | |
A reaction: He is making room for a person to retain identity despite having changed. Applause from me. |
6157 | Tokens are dated, concrete particulars; types are their general properties or kinds [Rowlands] |
Full Idea: Tokens are dated, concrete, particular occurrences or instances; types are the general properties that these occurrences exemplify or the kinds to which they belong. | |
From: Mark Rowlands (Externalism [2003], Ch.2) | |
A reaction: It might be said that types are sets, of which tokens are the members. The question of 'general properties' raises the question of whether universals must exist to make kinds possible. |
