This paper contributes to a debate that has arisen in the recent self-knowledge literature between agentialists and empiricists. According to agentialists, in order for one to know what one believes, desires, and intends, rational agency needs to be exercised in centrally significant cases. Empiricists disagree: while they acknowledge the importance of rationality in general, they maintain that when it comes to self- knowledge, empirical justification, or warrant, is always sufficient. In what follows, I defend agentialism. I argue that if we (...) could only come to know our judgement-sensitive attitudes in the way described by empiricism, then we would be self-estranged from them when we acquire knowledge of them. We would relate to our own attitudes as if we were watching the movies of our inner lives unfold. Given that this is not the position we typically inhabit, with respect to our judgement-sensitive attitudes, I conclude that empiricism fails. This is the self-estrangement argument against empiricism. I then consider a response that Brie Gertler, an empiricist, offers to the objection that empiricism fatally portrays us ‘mere observers of a passing cognitive show’ (2016, p. 1). I argue that her response is unsuccessful. Hence, we should endorse agentialism. (shrink)
