Single Idea 16991

[catalogued under 9. Objects / E. Objects over Time / 1. Objects over Time]

Full Idea

Adequate necessary and sufficient conditions for identity which do not beg the question are very rare. I don't know of such conditions for identity of material objects over time, or for people. Everyone knows what a problem this is.

Gist of Idea

No one seems to know the identity conditions for a material object (or for people) over time

A Reaction

Typical of Kripke, who only seems to commit to conclusions suggested to him by his modal logic, and is baffled by almost everything else. I think one can at least attempt an essentialist approach to this problem.
