Dretske on Introspection and Knowledge

In Naturalizing the Mind, Fred Dretske articulates and defends a naturalistic theory of the mind which he calls «the Representation Thesis.» In brief, this thesis states that «(1) All mental facts are representational facts, and (2) All representational facts are facts about information functions.» From this it follows that introspective knowledge, the mind's direct knowledge of its own states, is a case of «displaced perception»-that is, knowledge of mental (i.e., representational) facts through an awareness of external (i.e., physical) objects. In an earlier work, Dretske presents a general account of knowledge which is intended to circumvent Gettier-type counterexamples. According to this view, S knows that P if and only if: (1) S believes, without doubt, reservation, or question, that P is the case; (2) P is the case; (3) S has a reason, R, for believing that P such that, if P were not the case, then S would not have R (i.e., S has a conclusive reason, R, for believing that P). In this paper, my aim is to explore the relation between these two theories. After summarizing both in brief detail, I argue that Dretske's account of introspective knowledge cannot be reconciled with his account of knowledge broadly construed.
