 However none of the other answers seem to be entirely adequate either. It may seem, as in 1, that you could still be justified in believing F—in case your calculation was actually right—but no longer have strong enough reason to believe that the calculation was right. However, this would also mean that you could justifiably believe “F, but my overall evidence doesn’t support F”. Feldman (2005: 110–111) argues that it is impossible for this belief to be both true and reasonable since the second conjunct undermines the reasonableness of the first conjunct (cf. Bergmann 2005: 243; Gibbons 2006: 32; Adler 2002). And if you were aware of having this belief then you would be believing something that you know is unreasonable if true. You would be, in the view of Feldman and others, disrespecting the evidence. The state in which you believe “F and my evidence does not support F” is a case of “level-splitting”, also called epistemic akrasia, because you believe you ought not to have a particular belief state but you have it anyway.
