Full Idea
We might agree with Wiggins's theory of individuation, but reject his thesis that a thing's principle of individuation (of distinctness and persistence) must be preserved in all counterfactual situations.
Gist of Idea
We can accept criteria of distinctness and persistence, without making the counterfactual claims

A Reaction
I'm not even convinced that initial individuation consists of falling under a sortal, and I prefer to discuss the powers of the thing, rather than counterfactual facts about behaviour.
