Contrastive Knowledge Surveyed

Suppose that Ann says, “Keith knows that the bank will be open tomorrow.” Her audience may well agree. Her knowledge ascription may seem true. But now suppose that Ben—in a different context—also says “Keith knows that the bank will be open tomorrow.” His audience may well disagree. His knowledge ascription may seem false. Indeed, a number of philosophers have claimed that people’s intuitions about knowledge ascriptions are context sensitive, in the sense that the very same knowledge ascription can seem true in one conversational context but false in another. This purported fact about people’s intuitions serves as one of the main pieces of evidence for epistemic contextualism, which is (roughly speaking) the view that the truth conditions of a knowledge attribution can differ from one conversational context to another. Opponents of contextualism have replied by trying to explain these purported intuitions in other ways. For instance, they have proposed that these purported intuitions may be explained via shifts in what is at stake for the subject, pragmatic shifts in what is assertible, or performance shifts in our liability to error. Yet a recent series of empirical studies threatens to undermine this whole debate. These studies presented ordinary people with precisely the sorts of cases that have been discussed in the contextualism literature and gave them an opportunity to say whether they agreed or disagreed with the relevant knowledge attributions. Strikingly, the results suggest that people simply do not have the intuitions they were purported to have. Looking at this recent evidence, it is easy to come away with the feeling that the whole contextualism debate was founded on a myth. The various sides offered
