Single Idea 12763

[filed under theme 9. Objects / D. Essence of Objects / 7. Essence and Necessity / b. Essence not necessities ]

Full Idea

We can remain anti-essentialist while allowing some necessary properties: those essential to everything (self-identity), relational properties (being what it is), and world-indexed properties (being snub-nosed-only-in-Kronos).

Gist of Idea

Necessarily self-identical, or being what it is, or its world-indexed properties, aren't essential

Robert C. Stalnaker (Anti-essentialism [1979], p.73)

A Reaction

[a summary] He defined essential properties as necessary properties (Idea 12761), and now backpeddles. World-indexed properties are an invention of Plantinga, as essential properties to don't limit individuals. But they are necessary, not essential!
