Recent social psychology is skeptical about self-knowledge. Philosophers, on the other hand, have produced a new account of the source of the authority of self-ascriptions. On this account, it is not descriptive accuracy but authorship which funds the authority of one's self-ascriptions. The resulting view seems to ensure that self-ascriptions are authoritative, despite evidence of one's fallibility. However, a new wave of psychological studies presents a powerful challenge to the authorship account. This research suggests that one can author one's attitudes, but one's self- ascriptions may lack authority. I present this new challenge from social psychology and use it to argue that first-person authority is agential authority: one's self-ascriptions are authoritative, in part anyway, because they are reliable expressions of those attitudes that govern further choices and behavior

Epistemic closure, the idea that knowledge is closed under known implication, plays a central role in current discussions of skepticism and the semantics of knowledge reports. Contextualists in particular rely heavily on the truth of epistemic closure in staking out their distinctive response to the so-called "skeptical paradox." I argue that contextualists should re-think their commitment to closure. Closure principles strong enough to force the skeptical paradox on us are too strong, and closure principles weak enough to express unobjectionable epistemic principles are too weak to generate the skeptical paradox. I briefly consider how the contextualist might live without (strong) closure.
