Abstract

Contextualists explain certain intuitions regarding knowledge ascriptions by means of the thesis that 'knowledge' behaves like an indexical. This explanation denies what Peter Unger has called invariantism, i.e., the idea that knowledge ascriptions have truth value independent of the context in which they are issued. This paper aims to provide an invariantist explanation of the contextualist's intuitions, the core of which is that 'knowledge' has many different senses.
