Single Idea 9120
[filed under theme 7. Existence / D. Theories of Reality / 10. Vagueness / c. Vagueness as ignorance
]
Full Idea
Vagueness in a concept is its indiscriminability from other possible concepts; this can be reconciled with our knowledge of vague terms.
Gist of Idea

A Reaction
Sorensen objects that this makes vagueness too relative to members of a speech community. He prefers 'absolute borderline cases'. If you like the epistemic view, then Williamson seems more plausible. My 'vague' might differ from yours.
