 A second author who thinks that our understanding of the concept of knowledge can have important ramifications for the value of knowledge is Edward Craig (1990). Craig’s project begins with a thesis about the value of the concept of knowledge. Simplifying somewhat, Craig hypothesises that the concept of knowledge is important to us because it fulfills the valuable function of enabling us to identify reliable informants. The idea is that it is clearly of immense practical importance to be able to recognize those from whom we can gain true beliefs, and that it was in response to this need that the concept of knowledge arose. As with Hawthorne’s theory, this proposal, if correct, could potentially offer a resolution of at least the secondary value problem.
