Single Idea 16129

[catalogued under 7. Existence / D. Theories of Reality / 10. Vagueness / b. Vagueness of reality]

Full Idea

Evans tries to derive a contradiction from the supposition that a given identity statement is of indeterminate truth-value. (As it happens, I consider that this argument is flawed)

Gist of Idea

Evans argues (falsely!) that a contradiction follows from treating objects as vague

A Reaction

A priori, I wouldn't expect to be able to settle the question of whether there are any vague objects simply by following some logical derivation. Empirical examination, and conceptual analysis (or stipulation) have to be involved.
