ABSTRACT: Contextualism is the view that the word ‘knows’ is context sensitive and shifts according to the relevant standards in play. I argue that Contextualism is best paired with internalism about contexts. That is to say, an attributor’s context is completely determined by mental facts. Consequently, in the absence of awareness, external facts do not lead to contextual shifts. I support this view by appealing to the typical cases contextualists employ, such as DeRose’s Bank Cases and Cohen’s Airport Case. I conclude by reflecting on the nature of attributor’s themselves, and suggest this also supports the view that Contextualism is internalistic about contextual shifts.
