 One important view of this sort is that defended by Edward Craig (1990). Craig’s entry-point into the analysis of knowledge was not intuitions about cases, but rather a focus on the role that the concept of knowledge plays for humans. In particular, Craig suggested that the point of using the category of knowledge was for people to flag reliable informants—to help people know whom to trust in matters epistemic. Craig defends an account of knowledge that is designed to fill this role, even though it is susceptible to intuitive counterexamples. The plausibility of such accounts, with a less intuitive extension but with a different kind of theoretical justification, is a matter of controversy.
