Full Idea
Some would say that annihilating grains of stone from the statue of David (playing the 'Sorites Game') could never make its identity vague, because metaphysical vagueness is simply unintelligible.
Clarification
The 'Sorites Game' tests identity by gradually removing parts
Gist of Idea
A crumbling statue can't become vague, because vagueness is incoherent

A Reaction
He cites Russell, Dummett and Lewis in support. But Russell is a logical atomist, and Lewis says identity is composition. It strikes me as obvious that identity can be vague; the alternative is the absurdities of the Sorites paradox.
