"Knowledge and Its Limits presents a systematic new conception of knowledge as a fundamental kind of mental state sensitive to the knower's environment. It makes a major contribution to the debate between externalist ad internalist philosophies of mind, and breaks radically with the epistemological tradition of analysing knowledge in terms of true belief. The theory casts light on a wide variety of philosophical issues: the problem of scepticism, the nature of evidence, probability and assertion, the dispute between realism and anti-realism and the paradox of the surprise examination. Williamson relates the new conception to structural limits on knowledge which imply that what can be known never exhausts what is true. The arguments are illustrated by rigorous models based on epistemic logic and probability theory. The result is a new way of doing epistemology for the twenty-first century."--BOOK JACKET.

Eighteen leading philosophers offer critical assessments of Timothy Williamson's ground-breaking work on knowledge and its impact on philosophy today. They discuss epistemological issues concerning evidence, defeasibility, scepticism, testimony, assertion, and perception, and debate Williamson's central claim that knowledge is a mental state.

"For those new to philosophy, 'Tetralogue' is a marvellous way into the subject. For those who are old hands, it neatly poses serious questions about truth and falsity, relativism and dogma."--Dust jacket flap.

Imagination is celebrated as our vehicle for escape from the mundane here and now. It transports us to distant lands of magic and make-believe. It provides us with diversions during boring meetings or long bus rides. It enables creation of new things that the world has never seen. Yet the focus on imagination as a means of escape from the real world minimizes the fact that imagination seems also to furnish us with knowledge about it. Imagination seems an essential component in our endeavor to learn about the world in which we live--whether we're planning for the future, aiming to understand other people, or figuring out whether two puzzle pieces fit together. But how can the same mental power that allows us to escape the world as it currently is also inform us about the world as it currently is? The ten original essays in Knowledge Through Imagination, along with a substantial introduction by the editors, grapple with this neglected question; in doing so, they present a diverse array of positions ranging from cautious optimism to deep-seated pessimism. Many of the essays proceed by considering specific domains of inquiry where imagination is often employed--from the navigation of our immediate environment, to the prediction of our own and other peoples' behavior, to the investigation of ethical truth. Other essays assess the prospects for knowledge through imagination from a more general perspective, looking at issues of cognitive architecture and basic rationality. Blending perspectives from philosophy of mind, cognitive science, epistemology, aesthetics, and ethics, Knowledge Through Imagination sheds new light on the epistemic role of imagination.

What does 'if' mean? Timothy Williamson presents a controversial new approach to understanding conditional thinking, which is central to human cognitive life. He argues that in using 'if' we rely on psychological heuristics, fast and frugal methods which can lead us to trust faulty data and prematurely reject simple theories.

'Knowledge-First' constitutes what is widely regarded as one of the most significant innovations in contemporary epistemology in the past 25 years. Knowledge-first epistemology is the idea that knowledge per se should not be analysed in terms of its constituent parts (e.g., justification, belief), but rather that these and other notions should be analysed in terms of the concept of knowledge. This volume features a substantive introduction and 13 original essaysfrom leading and up-and-coming philosophers on the topic of knowledge-first philosophy. The contributors' essays range from foundational issues to applications of this project to other disciplinesincluding the philosophy of mind, the philosophy of perception, ethics and action theory. Knowledge First: Approaches in Epistemology and Mind aims to provide a relatively open-ended forum for creative and original scholarship with the potential to contribute and advance debates connected with this philosophical project.

The expanded new edition of one of the most influential and controversial books about the nature of philosophy published in the past several decades The 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 contemporary philosophy developed from naturalism, the linguistic turn, postmodern irony, and other prominent trends of the twentieth century. Viewing the method of philosophy as evolving from non-philosophical pursuits, Williamson provides readers with fresh insight into the “self-image” of philosophy and offers new ways of understanding what philosophy is and how it actually works. Now in its second edition, this landmark volume comprises the original book and the author’s subsequent work. New topics include the recent history of analytic philosophy, assessments of experimental philosophy, theories of concepts and understanding, Wittgensteinian approaches, popular philosophy, naturalism, morally-loaded examples in philosophy, philosophical applications of scientific methods, and many more. This edition features the author’s latest thoughts on a variety of issues, autobiographical reflections, and replies to critics. Proposes an alternative narrative about the nature of philosophy Argues that the common assumption of philosophical exceptionalism is false Highlights the similarities between philosophy and the other sciences in both methodology and subject matter Explores why contemporary philosophy has failed to articulate an adequate methodology Emphasizes increasing the methodological standards of reasoning in philosophy The Philosophy of Philosophy, Second Edition remains essential reading for philosophers, scholars, graduate and advanced undergraduate students in philosophy, and other readers with a sustained interest in the method and rationale of the doing of philosophy.
