Full Idea
Scientific essentialism is less concerned with questions of identity, and more with questions of explanation, than is the essentialism of Aristotle or of Kripke. It is closest to the kind of essentialism described by Locke.

A Reaction
Locke is popularly held to be anti-essentialist, but that is only because of his epistemological problems. I think Ellis is here misreading Aristotle, and I would ally Aristotle, Locke (cautiously), Leibniz, Ellis and Fine against Kripkeans on this one.
