In the blink of an eye, I can redirect my thought from London to Austin, from apples to unicorns, from former president Obama to the mythical flying horse, Pegasus.How is this possible? How can we think about things that do not exist, like unicorns and Pegasus? They are not there to be thought about, yet we think about them just as easily as we think about things that do exist.Thinking About Things addresses these and related questions, taking as its framework a representational theory of mind. It explains how mental states are attributed, what their aboutness consists in, whether or not they are relational, and whether any of them involve nonexistent things.The explanation centers on a new theory of what is involved in attributing attitudes like thinking, hoping, and wanting. These attributions are intensional: some of them seem to involve nonexistent things, and they typically have semantic and logical peculiarities, like the fact that one cannot always substitute one expression for another that refers to the same thing without affecting truth. Mark Sainsburys new theory, display theory, explains these anomalies. For example, substituting coreferring expressions does not always preserve truth because the correctness of an attribution depends on what concepts it displays, not on what the concepts refer to. And a concept that refers to nothing may be used in an accurate display of what someone is thinking.

How can one think about the same thing twice without knowing that it's the same thing? How can one think about nothing at all (for example Pegasus, the mythical flying horse)? Is thinking about oneself special? One could mistake one's car for someone else's, but it seems one could not mistake one's own headache for someone else's. Why not?Mark Sainsbury and Michael Tye provide an entirely new theory--called 'originalism'-- which provides simple and natural solutions to these puzzles and more. Originalism's central thesis is that concepts, the constituents of thoughts, are to be individuated by their origin, rather than epistemically or semantically. The doctrine has further valuable consequences for the nature of thought, our knowledge of our own thoughts, the nature of experience, the epistemology of perception-based beliefs, and for arguments based on conceivability. Sainsbury and Tye argue that although thought is special, there is no special mystery attaching to the nature of thought. Their account of the mind considers it as part of nature, as opposed to something with supernatural powers--which means that human beings have more opportunities to make mistakes than many have liked to think.

Frege is now regarded as one of the world's greatest philosophers, and the founder of modern logic. Mark Sainsbury argues that we must depart considerably from Frege's views if we are to work towards an adequate conception of natural language. This is an outstanding contribution to philosophy of language and logic and will be invaluable to all those interested in Frege and the philosophy of language.

Logical Forms explains both the detailed problems involved in finding logical forms and also the theoretical underpinnings of philosophical logic. In this revised edition, exercises are integrated throughout the book. The result is a genuinely interactive introduction which engages the reader in developing the argument. Each chapter concludes with updated notes to guide further reading.
