ABSTRACT
I have examined Wittgenstein’s critique of classical sense-datum theories, according to which such theories are rooted in a literal construal of the figurative analogy between physical and phenomenal space (see especially §§2.3, 3.2). The power of that analogy to mislead, I have suggested, transcends its capacity to make us look for phenomenal objects. It extends also to its support for the logical privacy of experience (§§3.3, 3.4, 4.3) and to the epistemic interpretation of first-person authority (§§4.1-4.4). Moreover, as I noted in §4.3, many philosophers who have rejected the act-object analysis of perception (§1.2) have still clung to the logical privacy of experience.
