1946
Silver Professor of Philosophy at New York University. His 1975 paper "Vagueness, Truth and Logic" gave supervaluationism its definitive form, showing how a vague language can be evaluated across all its admissible sharpenings while preserving the logical truths of classical logic. He has since moved away from that view himself.
