The paper explores a possible connection between epistemic contextualism and hinge epistemology. My basic idea is that Wittgenstein’s hinge propositions play a possibility-governing role, in the sense that they govern our knowledge attributions by determining which possibilities count as relevant alternatives. This is a novel proposal with several theoretical advantages for both hinge epistemology and epistemic contextualism. On the one hand, in order to offer a substantial account of the way in which knowledge attributions work, the contextualist needs more than (...) mere formal tools. She needs to tell us what goes inside the contexts that govern our conversations. On the other hand, the hinge epistemologist cannot be satisfied by mere metaphors (like the hinge metaphor). She needs to tell us how hinges can effectively govern our conversations. I take hinge contextualism to be the answer. With the help of hinges, we can furnish contexts; and with the help of contexts, we can put hinges at work. (shrink)

A very natural view about perceptual knowledge is articulated, one on which perceptual knowledge is closely related to perceptual discrimination, and which fits well with a relevant alternatives account of knowledge. It is shown that this kind of proposal faces a problem, and various options for resolving this difficulty are explored. In light of this discussion, a two-tiered relevant alternatives account of perceptual knowledge is offered which avoids the closure problem. It is further shown how this proposal can: accommodate our (...) intuitions about perceptual knowledge and perceptual discrimination in terms of the notion of primary relevance, give an account of how alternatives can be rationally excluded without appeal to perceptual discrimination in terms of the notion of secondary relevance, and deal with the problem posed by inverted Gettier cases, and hence explain what it means to rationally exclude alternatives which are of secondary relevance.
