On the Vagueness of “Know” as a Gradable Term

Epistemic contextualists interpreted the predicate “know” either as indexical, comparable to expressions like “I”, “here” or “this”, or as a gradable term, like “tall or “flat”. Mark Heller (1999) categorized “know” as a broadly vague term. In this paper, it is argued that “know” does behave or can be considered as a vague term, rather than only as indexical or gradable. In contrast to Heller's contextualist interpretation, the vagueness of “know” can be explained in a non- contextualist manner by referring to its intra- contextual gradability, which is not due to inter- contextually shifting standards.
