It has been objected, however, that regardless of which model is adopted, the linguistic data surrounding ‘know’ and cognate expressions is not what one would expect were the term genuinely context-sensitive. For example, Jason Stanley (2004) argues that, unlike terms like ‘flat’ and ‘tall’, ‘know’ is not clearly gradable. Thus, it makes sense to describe someone as “very tall”; but while I might say that someone knows something “very well,” ‘very’ does not appear here to be functioning as a degree modifier. And while ‘justified’ is obviously gradable, even if gradability were sufficient for context-sensitivity, from the fact that knowledge requires justification it would not follow that ‘know’ is context-sensitive as well (pace Cohen 1999, 60). Nor, Stanley argues, does ‘know’ behave like indexicals (‘I’, ‘here’) or relational terms (such as ‘enemy’).
