 But a relevant alternatives compatibilist might still rescue the Cartesian intuition. First, note that in many slow switch arguments, the issue is not whether Oscar knows that he thinks that p from the armchair; rather, it is whether Oscar knows what he thinks. And unlike ascriptions of “knowledge that,” ascriptions of “knowledge what” are appropriate only relative to one’s goals or purposes in a context (Boër &amp; Lycan 1986, Braun 2006, DeRose 2009, ch. 2,  appendix).[22]  Hence, whether it is apt to say “Oscar knows what he thinks” partly depends on contextually salient goals or purposes. Granted, if Oscar’s goal is to discriminate between a content and a twin content, then he cannot “know what” he thinks from the armchair. However, it may be that for other anti-skeptical purposes, Oscar can indeed “know what” (Parent 2015b, 2017, chs. 5 and 10). For instance, suppose the skeptic challenges Oscar on whether he knows the truth of anything with certainty. Then, if Oscar points to his self-verifying judgment (W) (“I am thinking forthwith that water is wet”) this could count as meeting the challenge. It is a case where the truth of his judgment is certain, even if its content is in question. So at least relative to that goal, Oscar may know what he thinks (Parent 2015b, 2017, ch. 5).
