This book maintains that our conception of consciousness and cognition begins with and depends upon a few fundamental errors. Thau elucidates these errors by discussing three important philosophical puzzles - Spectrum Inversion, Frege's Puzzle, and Black-and-White Mary - each of which concerns some aspect of either consciousness or cognition. He argues that it has gone unnoticed that each of these puzzles presents the very same problem and, in bringing this commonality to light, the errors in our natural conception of consciousness (...) and cognition are also reviewed.

Most philosophers agree that beliefs and perceptions represent the world to us and that a particular belief or perception is sometimes distinct from another particular belief or perception because what they represent is different; for example, one thing that distinguishes the belief that snow is white from the belief that grass is green is that the former represents snow while the latter represents grass. However, most philosophers of mind hold that a particular belief or perception is sometimes distinct from another (...) particular belief or perception because of how they represent. Indeed, though few philosophers explicitly recognize a distinction between what something represents and how it represents, the view that there is more to belief and perception than what they represent is about as close to philosophical orthodoxy as anything is. In this dissertation, I give a substantive account the relevant notion of representation and the distinction between what something represents and how it represents. I also bring out this hidden orthodoxy and argue that it is mistaken. Contrary to the orthodoxy, I defend the view that belief and perception present a single class of mental phenomena marked by their representational nature and that any mental difference between any two members of the class must be a difference in what they represent.

Richard Heck, in "The Sense of Communication" (Mind, 104, pp. 79-106, 1995), argues against the "Hybrid View"--the claim, roughly, that names are Millian while beliefs are Fregean. We argue that Heck's argument fails.

We prove that all proofs in -logic (a first order logic with -rule added) in which -rule is used finitely many times can be turned into proofs in which the -rule is used at most one time. Next, we prove that the word finitely above cannot be changed by the word infinitely.
