 In general, every indubitability account of certainty will face a dilemma: when the subject finds herself incapable of doubting one of her beliefs, either she has good reasons for being incapable of doubting it, or she does not. If she does not have good reasons for being unable to doubt the belief, the type of certainty in question can be only psychological, not epistemic, in nature. On the other hand, if the subject does have good reasons for being unable to doubt the belief, the belief may be epistemically certain. But, in this case, what grounds the certainty of the belief will be the subject’s reasons for holding it, and not the fact that the belief is indubitable.
