 In one sense, such accounts are in competition with one another, in that they offer different practical explications of ‘knowledge’. However, these accounts all accept (explicitly or tacitly) a more general insight, which is that considerations about the function that the concept of knowledge plays in fulfilling practical needs should inform our theories of the nature and corresponding value of knowledge. This more general point remains controversial in contemporary metaepistemology. For some arguments against supposing that a practical explication of ‘knowledge’, in terms of some need-fulfilling function, should inform our accounts of the nature or knowledge, see for example Gerken (2015). For a more extreme form of argument in favor of divorcing considerations to do with how and why we use ‘knows’ from epistemological theorizing altogether, see Hazlett (2010; cf. Turri 2011b).
