Single Idea 13971

[catalogued under 9. Objects / D. Essence of Objects / 14. Knowledge of Essences]

Full Idea

Kripke's first (good) route to the necessary a posteriori is based on the idea that certain properties of objects that they can be known to have only a posteriori, may be known a priori to be essential properties of anything that has them.

Gist of Idea

Kripke claims that some properties, only knowable posteriori, are known a priori to be essential

A Reaction

Interesting, and a key issue. I think this is precisely where I disagree with the Kripkean view of necessities. Logicians want to know a priori what is essential for identity, but scientists want to know what makes things tick. See Kripke on pain.
