Outlines the core of the author's theory, according to which the concept of knowledge arises because of our interest in having true beliefs about our environment and thus in evaluating sources of information, and is used to flag approved ones. The hypothesis is used to account for epistemologists’ disagreement over the precise nature of the belief condition for knowledge. Ground is conceded to those who play down the requirement, in so far as an informant's being confident that p is not always taken as necessary for her to be a good informant. Equally, cases in which an informant is regarded as good, yet lacks belief entirely, are freakish and thus of little practical use, which explains both the attraction of the requirement and the feeling that there are genuine counter-examples to it.
