 Contemporary contextualists include Michael Blome-Tillmann, Michael Williams, Stewart Cohen, Keith DeRose, David Lewis, Gail Stine, and George Mattey.The standards for attributing knowledge to someone, the contextualist claims, vary from one user's context to the next.Thus, if I say "John knows that his car is in front of him", the utterance is true if and only if (1) John believes that his car is in front of him, (2) the car is in fact in front of him, and (3) John meets the epistemic standards that my (the speaker's) context selects.
