 Klein says that the second condition is what makes the belief subjectively immune to doubt, presumably because it is the beliefs and experiences that constitute S’s subjective perspective that render her warranted in denying all propositions that would reduce the warrant for p. However, S’s belief system might contain false beliefs that could warrant her in denying every g relevant to p—even, in some cases, where the g in question is itself true—and so her belief that p might meet condition (2) and yet still be false. Condition (3) is meant to prevent this situation; if p is false, the true belief that ~p can be added to S’s belief system, thereby reducing the warrant S has for p. In requiring both (2) and (3), then, the account focuses on beliefs where the subject’s subjective situation is in a sense properly aligned with an objective structure of reasons (for a similar view, see Pollock 1986).
