Relativism and contextualism have been suggested as candidate semantics for “knowledge” sentences. I argue that relativism faces a problem concerning the preservation of beliefs in memory. Contextualism has been argued to face a similar problem. I argue that contextualists, unlike relativists, can respond to the concern. The overall upshot is that contextualism is superior to relativism in at least one important respect.

The possibility of knowledge attributions across contexts (where attributor and subject find themselves in different epistemic contexts) can create serious problems for certain views of knowledge. Amongst such views is subject—sensitive invariantism—the view that knowledge is determined not only by epistemic factors (belief, truth, evidence, etc.) but also by non—epistemic factors (practical interests, etc.). I argue that subject—sensitive invariantism either runs into a contradiction or has to make very implausible assumptions. The problem has been very much neglected but is so (...) serious that one should look for alternative accounts of knowledge. (shrink)
