For instance, an evidentialist account of knowledge can be an instance of contextualism if it's held that strength of justification is a contextually varying matter. And one who accepts a relevant alternative's account of knowledge can be a contextualist by holding that what range of alternatives are relevant is sensitive to conversational context. DeRose adopts a type of modal or "safety" (as it has since come to be known) account on which knowledge is a matter of one's belief as to whether or not p is the case matching the fact of the matter, not only in the actual world, but also in the sufficiently close possible worlds: Knowledge amounts to there being no "nearby" worlds in which one goes wrong with respect to p. But how close is sufficiently close? It's here that DeRose takes the modal account of knowledge in a contextualist direction, for the range of "epistemically relevant worlds" is what varies with context: In high standards contexts one's belief must match the fact of the matter through a much wider range of worlds than is relevant to low standards contexts.
