Single Idea 15146

[catalogued under 26. Natural Theory / B. Natural Kinds / 4. Source of Kinds]

Full Idea

Many of the kinds we theorize about and experiment on today simply do not have essences. We can distinguish 'essence kinds', such as electrons, and 'cluster kinds', such as biological species.

Gist of Idea

Some kinds, such as electrons, have essences, but 'cluster kinds' do not


Anjan Chakravarrty (Inessential Aristotle: Powers without Essences [2012], 2)

A Reaction

This is an important point for essentialists. He offers a strict criterion, in Idea 15145, for mind membership, but we might allow species to have essences by just relaxing the criteria a bit, and acknowledging some vagueness, especially over time.
