 A second kind of certainty is epistemic. Roughly characterized, a belief is certain in this sense when it has the highest possible epistemic status. Epistemic certainty is often accompanied by psychological certainty, but it need not be. It is possible that a subject may have a belief that enjoys the highest possible epistemic status and yet be unaware that it does. (More generally, a subject’s being certain that p does not entail that she is certain that she is certain that p; on this point, see Van Cleve 1979, and see Alston 1980 on level confusions in epistemology.) In such a case, the subject may feel less than the full confidence that her epistemic position warrants. I will say more below about the analysis of epistemic certainty and its relation to psychological certainty.
