 John Hawthorne (2004; cf. Stanley 2005; Fantl &amp; McGrath 2002) has argued that knowledge is valuable because of the role it plays in practical reasoning. More specifically, Hawthorne (2004: 30) argues for the principle that one should use a proposition p as a premise in one’s practical reasoning only if one knows p. Hawthorne primarily motivates this line of argument by appeal to the lottery case. This concerns an agent’s true belief that she holds the losing ticket for a fair lottery with long odds and a large cash prize, a belief that is based solely on the fact that she has reflected on the odds involved. Intuitively, we would say that such an agent lacks knowledge of what she believes, even though her belief is true and even though her justification for what she believes—assessed in terms of the likelihood, given this justification, of her being right—is unusually strong. Moreover, were this agent to use this belief as a premise in her practical reasoning, and so infer that she should throw the ticket away without checking the lottery results in the paper for example, then we would regard her reasoning as problematic.
