Some self-knowledge must be arrived at by the subject herself, rather than being transmitted by another’s testimony. Yet in many cases the subject interacts with an expert in part because she is likely to have the relevant knowledge of their mind. This raises a question: what is the expert’s knowledge like that there are barriers to simply transmitting it by testimony? I argue that the expert’s knowledge is, in some circumstances, proleptic, referring to attitudes the subject would hold were she (...) to reflect in certain ways. The expert’s knowledge cannot be transmitted by testimony because self-knowledge cannot be proleptic. (shrink)

Pessimists about moral testimony hold that there is something suboptimal about forming moral beliefs by deferring to another. This paper motivates an analogous claim about self-knowledge of the reason-responsive attitudes. When it comes to your own mind, it seems important to know things “from the inside”, in the first-personal way, rather than putting your trust in another. After motivating Pessimism, the paper offers an explanation of its truth. First-person knowledge is distinctive because it involves knowing a state of mind and (...) finding it intelligible from one’s point of view. It concludes by considering the value of this form of self-understanding. (shrink)
