[catalogued under 7. Existence / D. Theories of Reality / 9. Vagueness / b. Vagueness of reality]

Full Idea

Fuzzy boundaries do not in any way require vague identity. Objects are identical only if their boundaries have exactly the same fuzziness.

Gist of Idea

Equally fuzzy objects can be identical, so fuzziness doesn't entail vagueness


Timothy Williamson (Vagueness [1994], 9.2)

A Reaction

This all rests on the Fregean idea that determinate existence requires the ability to participate in an identity statement.
