Single Idea 17595

[catalogued under 9. Objects / F. Identity among Objects / 1. Concept of Identity]

Full Idea

The concept of identity is central in specifying spatio-temporally broad objects by ostension. Without identity, n acts of ostension merely specify up to n objects. ..But when we affirm identity of object between ostensions, they refer to the same object.

Gist of Idea

To unite a sequence of ostensions to make one object, a prior concept of identity is needed

A Reaction

Quine says that there is an induction involved. On the whole, Quine seems to give a better account of identity than Geach or Wiggins can offer.
