Four people with radically different outlooks on the world meet on a train and start talking about what they believe. Their conversation varies from cool logical reasoning to heated personal confrontation. Each starts off convinced that he or she is right, but then doubts creep in. In a tradition going back to Plato, Timothy Williamson uses a fictional conversation to explore questions about truth and falsity, and knowledge and belief. Is truth always relative to a point of view? Is every ...

In his Rutgers Lectures, Timothy Williamson explains how contemporary philosophy suffers from a widespread pathology known as overfitting to natural and social scientists, but little understood by most philosophers. Overfitting involves an insufficiently critical attitude towards data, which leads to over-complicated theories designed to fit what are in fact errors in the data. In philosophy, the data typically comprise verdicts on hypothetical or actual cases. Errors in such data...

What are philosophers trying to achieve? How can they succeed? Does philosophy make progress? Is it in competition with science, or doing something completely different, or neither? Timothy Williamson tackles some of the key questions surrounding philosophy in new and provocative ways, showing how philosophy begins in common sense curiosity, and develops through our capacity to dispute rationally with each other. Discussing philosophy's ability to clarify our thoughts, he explains why such...

Good as Usual argues that contemporary discussion on the nature of norms and values goes wrong by treating them as exceptional and mysterious, since they do not fit popular philosophical assumptions about metaphysics, epistemology, and the philosophy of language. Timothy Williamson shows that, once we throw out those preconceived and outdated ideas, we can understand moral and evaluative features of reality as similar to its other features, and capable of being known and described...

What does 'if' mean? It is one of the most commonly used words in the English language, in itself a sign to the importance of conditional thinking to human cognitive life. We make conditional statements, ask conditional questions, and issue conditional orders. We need to think and talk conditionally for many purposes, from everyday decision-making to mathematical proof. Yet the meaning of conditionals has been debated for thousands of years. Suppose and Tell brings together ideas ...

The Philosophy of PhilosophyThe Blackwell / Brown Lectures in PhilosophyThe Philosophy of Philosophy presents an original, unified concept of philosophy as a non-natural science. In this provocative work, distinguished philosopher Timothy Williamson challenges widely-held assumptions and clarifies long-standing misconceptions about the methodology and nature of philosophical inquiry. The author rejects the standard narratives of contempora...

What kind of knowledge could be obtainable just by thinking? Debating the A Priori presents a series of exchanges between two leading philosophers on how to answer this question. In this extended debate, Boghossian and Williamson contribute alternating chapters which develop radically contrasting views and present detailed replies to each other's arguments. A central case is the nature of basic logical knowledge and the justification for basic deductive inferences, but the argumen...

Are there such things as merely possible people, who would have lived if our ancestors had acted differently? Are there future people, who have not yet been conceived? Questions like those raise deep issues about both the nature of being and its logical relations with contingency and change. In Modal Logic as Metaphysics, Timothy Williamson argues for positive answers to those questions on the basis of an integrated approach to the issues, applying the technical resources of modal...

Identity and DiscriminationThis updated edition of Identity and Discrimination, first published in 1990 and the first book by well-known philosopher Timothy Williamson, is now reissued with the inclusion of significant new material. This major work – influential in philosophy of perception and the theory of vagueness – continues in an original and rigorous way to highlight the necessity of discrimination and the thresholds which determine the approximate c...

If you keep removing single grains of sand from a heap, when is it no longer a heap? From discussions of the heap paradox in classical Greece, to modern formal approaches like fuzzy logic, Timothy Williamson traces the history of the problem of vagueness. He argues that standard logic and formal semantics apply even to vague languages and defends the controversial, realist view that vagueness is a form of ignorance - there really is a grain of sand whose removal turns a heap into a non-hea...

A care bundle is a group of specific, non-prescriptive, evidence-based components that, when performed collectively and reliably, have been established to improve patient outcomes. Emergency medicine care bundles support healthcare professionals in providing focused management plans for common presentations. They are explicitly focused on the initi
