Abstract

Self-fulfilling beliefs are, in at least some cases, a kind of belief that is rational to form and hold in the absence of evidence. The rationality of such beliefs have significant implications for a range of debates in epistemology. Most startlingly, it undermines the idea that having sufficient evidence for the truth of is necessary for it to be rational to believe that. The rationality of self-fulfilling beliefs is here defended against the idea that their rationality is incompatible with a compelling closure principle.
