The Sorites Paradox
One grain of sand is not a heap. Adding a single grain never turns a non-heap into a heap. So heaps do not exist.

Wykeham Professor of Logic at the University of Oxford from 2000 to 2024. His 1994 book Vagueness is the canonical statement of epistemicism: the view that vague terms do have sharp boundaries and that vagueness is a form of ignorance, not of meaning. The position keeps classical logic intact at the cost of a claim most people find hard to swallow.
