[catalogued under 9. Objects / F. Identity among Objects / 9. Sameness]

Full Idea

When the identity relation is vague, it may seem intransitive; a claim of apparent identity may yield an apparent non-identity. Some sort of 'counterpart' notion may have some utility here.

Gist of Idea

A vague identity may seem intransitive, and we might want to talk of 'counterparts'

A Reaction

He firmly rejects the full Lewis apparatus of counterparts. The idea would be that a river at different times had counterpart relations, not strict identity. I like the word 'same' for this situation. Most worldly 'identity' is intransitive.
