Ordinarily, if a person produces a nonreflective, ‘unstudied’ self-attribution of a present mental state – an avowal – we do not presume that they have produced the avowal on some specific epistemic basis; and we do not expect them to know how they know the self-attribution to be true. This no-‘how’ character of basic self-knowledge is puzzling, given that we regard avowals as manifesting factual, and indeed privileged, knowledge. I am here interested in views that accommodate both the baseless, no-‘how’ (...) and the factual, privileged character of basic self-knowledge. I argue that leading constitutivist views, which embrace both, fail properly to meet the doxastic (as opposed to justificatory) requirement on basic self-knowledge, thereby failing to preserve its genuinely factual character. I then argue that an alternative, neo-expressivist approach is better placed to meet the doxastic requirement, as well as being at least as well-placed as constitutivist views to address the justificatory requirement on baseless self-knowledge.
