Sainsbury and Tye present a new theory, 'originalism', which provides natural, simple solutions to puzzles about thought that have troubled philosophers for centuries. They argue that concepts are to be individuated by their origin, rather than epistemically or semantically. Although thought is special, no special mystery attaches to its nature.

Research in mathematics is much more than solving puzzles, but most people will agree that solving puzzles is not just fun: it helps focus the mind and increases one's armory of techniques for doing mathematics. Mathematical Puzzles makes this connection explicit by isolating important mathematical methods, then using them to solve puzzles and prove a theorem. Features A collection of the world’s best mathematical puzzles Each chapter features a technique for solving mathematical puzzles, examples, and finally a genuine theorem of mathematics that features that technique in its proof Puzzles that are entertaining, mystifying, paradoxical, and satisfying; they are not just exercises or contest problems.

Fully illustrated in color, this treasure trove features 250 puzzles on every imaginable theme and subject. The book is a bonanza of mazes, word games, visual and logic puzzles, and more.

Besides being fun, puzzles increase student involvement and can lead to higher scores on problem-solving tests. Each book in this series has over 175 activities divided into four categories: picture, word, number, and logic. The puzzles are for individual students; the games are designed for pairs. Teachers can use them as fill-in activities for early finishers, to spice up homework packets, or as part of a reward system or weekly challenge. Beware! These puzzles can be addictive!

Establishing trans philosophy as a unique field of inquiry, offering tools for our quest toward a more just and equitable world Trans Philosophy defines this burgeoning and polymorphous discipline as philosophical work that is accountable to and illuminative of cross-cultural and global trans experiences, histories, and cultural productions. Across language and politics, feminism and phenomenology, and decolonial theory, it addresses trans worldmaking in all its beauty and mundanity. Critically, the editors center the contributions of trans and gender-nonconforming philosophers from around the globe. Showcasing work from a range of emerging and established voices, Trans Philosophy addresses discrimination, embodiment, identity, language, and law, utilizing diverse philosophical methods to attend to significant intersections between trans experience and class, disability, race, nationality, and sexuality. At a time when trans-exclusionary views are gaining traction in politics as well as philosophy, this volume urgently redraws the contours of trans discourse, centering the wisdom already generated in trans and other gender-disruptive communities.

Written by an international team of leading scholars, this collection of thirteen new essays explores the implications of semantic externalism for self-knowledge and skepticism, bringing recent developments in the philosophy of mind, the philosophy of language, and epistemology to bear on the issue. Structured in three parts, the collection looks at self-knowledge, content transparency, and then meta-semantics and the nature of mental content. The chapters examine a wide range of topics in the philosophy of mind and the philosophy of language, including 2D semantics, transparency views of self-knowledge, and theories of linguistic understanding, as well as epistemological debates on contextualism, contrastivism, pragmatic encroachment, anti-luminosity arguments and testimony. The scope of the volume will appeal to graduate students and researchers in epistemology, philosophy of mind, philosophy of language, cognitive science, psychology and linguistics.

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.

Cora Felton, the Puzzle Lady, is stunned when Benny Southstreet, a two-bit gambler, accuses her of stealing a crossword puzzle, a case that is further complicated when her own attorney files a plagiarism suit against her and the police arrest her for murder.

This volume attempts to solve a grave problem about critical self-reflection. The worry is that we critical thinkers are all in "epistemic bad faith" in light of what psychology tells us. After all, the research shows not merely that we are bad at detecting "ego-threatening" thoughts à la Freud. It also indicates that we are ignorant of even our ordinary thoughts—e.g., reasons for our moral judgments of others (Haidt 2001), and even mundane reasons for buying one pair of stockings over another! (Nisbett & Wilson 1977) However, reflection on one’s thoughts requires knowing what those thoughts are in the first place. So if ignorance is the norm, why attempt self-reflection? The activity would just display naivety about psychology. Yet while respecting all the data, this book argues that, remarkably, we are sometimes infallible in our self-discerning judgments. Even so, infallibility does not imply indubitability, and there is no Cartesian ambition to provide a "foundation" for empirical knowledge. The point is rather to explain how self-reflection as a rational activity is possible.

Mental fragmentation is the thesis that the mind is fragmented, or compartmentalized. Roughly, this means that an agent's overall belief state is divided into several sub-states-fragments. These fragments need not make for a consistent and deductively closed belief system. The thesis of mental fragmentation became popular through the work of philosophers like Christopher Cherniak, David Lewis, and Robert Stalnaker in the 1980s, and has recently attracted increased attention. This volume is the first collection of essays devoted to the topic of mental fragmentation. It features important new contributions by leading experts in the philosophy of mind, epistemology, and philosophy of language. Opening with an accessible introduction providing a systematic overview of the current debate, the fourteen essays cover a wide range of issues: foundational issues and motivations for fragmentation, the rationality or irrationality of fragmentation, fragmentation's role in language, the relationship between fragmentation and mental files, and the implications of fragmentation for the analysis of implicit attitudes.
