 Stalnaker suggests an alternative way in which Mary’s new knowledge is demonstrative in character. On this proposal, what Mary acquires is essentially contextual information, where “the content of what is expressed or believed in a context is not detachable from the context in which it is expressed or believed” (2008, 81). As an example of such information, Stalnaker describes a bomb disposal expert pointing at the ground and saying “A bomb is buried there, and unless we defuse it now it will explode within five minutes” (2008, 85). This information, Stalnaker suggests, cannot be known by someone who was not in that situation at that time, even if they know the exact co-ordinates of where the bomb is located and when it will detonate. Daniel Stoljar (2011) argues that phenomenal knowledge is not essentially contextual. In defence of this claim, he suggests there is an important dis-analogy between the difference between Mary, pre- and post-release, and the difference between the bomb disposal expert and anyone who was not with her when she made her utterance. The thought which the bomb disposal expert expressed in her utterance could not even be entertained by someone who was not present at that time; it is for this reason that someone not there could not know what the expert knew. In contrast, Stoljar suggests that “the fact that post-release Mary learnt could have been entertained by pre-release Mary (e.g., she can wonder whether it obtains)” (2011, 441). This suggests that what Mary learns upon release is not essentially contextual, at least not in the sense which Stalnaker has in mind.
