In this paper, I attempt to demonstrate the structure of Sellars' critical direct realism in the philosophy of perception. This position is original because it attempts to balance two claims that many have thought to be incompatible: (1) that perceptual knowledge is direct, i.e., not inferential, and (2) that perceptual knowledge is irreducibly conceptual. Even though perceptual episodes are not the result of inferences, they must still stand within the space of reasons if they are to be counted not only (...) as knowledge, but also as thoughts directed at the world. The goal of this paper is to demonstrate how Sellars elaborates and defends this position. (shrink)
