Single Idea 7693

[filed under theme 10. Modality / E. Possible worlds / 3. Transworld Objects / b. Rigid designation ]

Full Idea

Objects we find in the actual world might have been so different than they actually are that it appears impossible to identify the same objects from world to world. Kripke sidesteps the problem by saying transworld identity is a decision, not a discovery.

Gist of Idea

Kripke avoids difficulties of transworld identity by saying it is a decision, not a discovery

A Reaction

This is the strategy that opposes Lewis's proposal of 'counterpart' objects that have properties in common. It is also the source of Kripke's causal theory of reference, and hence a key to massive modern debates.
