Knowledge ascriptions of the form ‘S knows that p’ are a central area of research in philosophy. But why do humans think and talk about knowledge? What are knowledge ascriptions for? This article surveys a variety of proposals about the role of knowledge ascriptions and attempts to provide a unified account of these seemingly distinct views.

If epistemic contextualism is correct, then knowledge attributions do not have stable truth-conditions across different contexts. John Hawthorne, Timothy Williamson, and Patrick Rysiew argue that this unstable picture of knowledge attributions undermines the role that knowledge reports play in storing, retrieving, and transmitting useful information. Contrary to this view, I argue that the truth-conditions of knowledge attributions are more stable than critics have claimed, and that contextualism is compatible with the role knowledge attributions play in storing, retrieving, and transmitting information (...) across contexts. In particular, I discuss a social dimension of ‘knowledge’ that limits contextual variability. This indicates a new way of characterizing contextualism. (shrink)

Edward Craig has proposed that epistemology should eschew traditional conceptual analysis in favor of what he calls “conceptual synthesis.” He proposes we start not from the finding of necessary and sufficient conditions that match our intuitions; rather we start from considerations on what the concept of knowledge does for us. In this paper I will explore one aspect of Craig’s proposal – the good informant. It is this aspect that is central to Craig’s epistemic method and perhaps most problematic. I (...) will evaluate this concept by first articulating three initial worries that some have had about the concept and then show how each of the initial worries can be quelled by looking deeper into the features of what Craig’s proposal is. I then assess Craig’s proposal on its own terms by looking at the concept of a good informant in light of the criteria for an adequate explication. What I will show is that while there is much to be sympathetic with in Craig’s proposal, there are some open questions that need to be solved in order to say that an adequate explication has been reached.
