    This paper critically examines currently influential transparency accounts of our knowledge of our own beliefs that say that self-ascriptions of belief typically are arrived at by “looking outward” onto the world. For example, one version of the transparency account says that one self-ascribes beliefs via an inference from a premise to the conclusion that one believes that premise. This rule of inference reliably yields accurate self-ascriptions because you cannot infer a conclusion from a premi…Read more

    Is Memory Merely Testimony from One's Former Self?
    Philosophical Review 124 (3): 353-392. 2015.
    A natural view of testimony holds that a source's statements provide one with evidence about what the source believes, which in turn provides one with evidence about what is true. But some theorists have gone further and developed a broadly analogous view of memory. According to this view, which this essay calls the “diary model,” one's memory ordinarily serves as a means for one's present self to gain evidence about one's past judgments, and in turn about the truth. This essay rejects the diary…Read more

    Perceptual Justification and the Cartesian Theater
    Oxford Studies in Epistemology 6. forthcoming.

If you are to justifiably believe that the wall is red, you must be in a position to justifiably infer this conclusion about the externa…Read more

    What’s the matter with epistemic circularity?
    Philosophical Studies 171 (2): 177-205. 2014.
    If the reliability of a source of testimony is open to question, it seems epistemically illegitimate to verify the source’s reliability by appealing to that source’s own testimony. Is this because it is illegitimate to trust a questionable source’s testimony on any matter whatsoever? Or is there a distinctive problem with appealing to the source’s testimony on the matter of that source’s own reliability? After distinguishing between two kinds of epistemically illegitimate circularity—bootstrappi…Read more
