This collection of essays by eminent philosopher Fred Dretske brings together work on the theory of knowledge and philosophy of mind spanning thirty years. The two areas combine to lay the groundwork for a naturalistic philosophy of mind. The essays focus on perception, knowledge, and consciousness. Together, they show the interconnectedness of Dretske's work in epistemology and his more contemporary ideas on philosophy of mind, shedding light on the links that can be made between the two. This collection will be a valuable resource for a wide range of philosophers and their students, and will also be of interest to cognitive scientists, psychologists, and philosophers of biology.

Does the self - a unified, separate, persisting thinker/owner/agent - exist? Drawing on Western philosophy, neurology and Theravadin Buddhism, this book argues that the self is an illusion created by a tier of non-illusory consciousness and a tier of desire-driven thought and emotion, and that separateness underpins the self's illusory status.

Carl Gustav Hempel (1905-97) was one of the preeminent figures in the philosophical movement of logical empiricism. He was a member of both the Berlin and Vienna circles, fled Germany in 1934 and finally settled in the US where he taught for many years in New York, Princeton, and Pittsburgh. The essays in this collection come from the early and late periods of Hempel's career and chart his intellectual odyssey from a rigorous commitment to logical positivism in the 1930s (when Hempel allied himself closely with Carnap) to a more sociological approach close in spirit to the work of Neurath and Kuhn. The collection brings together essays which have up till now been difficult to find, four of which are appearing in English for the first time. Cumulatively they offer a fresh perspective on Hempel's intellectual development and on the rise and demise of logical empiricism.

Carl G. Hempel (1905-1997) was one of the preeminent figures in the philosophical movement of logical empiricism. The essays in this collection come from the early and late periods of Hempel's career. Most of these essays are hard to track down and four of them are appearing in English for the first time. Cumulatively they offer a fresh perspective on Hempel's intellectual development and on the rise and demise of logical empiricism. Richard Jeffrey has prepared the collection for publication, and has supplied introductory surveys to the essays as well as a brief biographical sketch of Hempel.

This volume collects the most substantial correspondence and documents relating to Wittgenstein's long association with Cambridge between the years 1911 and his death in 1951, including the letters he exchanged with his most illustrious Cambridge contemporaries Russell, Keynes, Moore, and Ramsey (and previously published as Cambridge Letters). * Now expanded to include 200 previously unpublished letters and documents, including correspondence between Wittgenstein and the economist Piero Sraffa, and between Wittgenstein and his pupils * Includes extensive editorial annotations * Provides a fascinating and intimate insight into Wittgenstein's life and thought

Ludwig Wittgenstein (1889-1951) is one of the most important and influential philosophers in modern times, but he is also one of the least accessible. In this volume, leading experts chart the development of his work and clarify the connections between its different stages. The essays, which are both expository and original, address central themes in Wittgenstein's writing on a wide range of topics, particularly his thinking about the mind, language, logic, and mathematics. The contributors illuminate the character of the whole body of work by focusing on key topics: the style of the philosophy, the conception of grammar contained in it, rule-following, convention, logical necessity, the self, and what Wittgenstein called, in a famous phrase, 'forms of life'. This revised edition includes a new introduction, five new essays - on Tractarian ethics, Wittgenstein's development, aspects, the mind, and time and history - and a fully updated comprehensive bibliography.

This is the first collection of papers devoted to Ludwig Wittgenstein's cryptic but brilliant "On Certainty." This work, Wittgenstein's last, extends the thinking of his earlier, better known writings, and in so doing, makes the most important contribution to epistemology since Kant's "Critique of Pure Reason"--a claim the essays in this volume help to demonstrate. The essays have been grouped under four headings, reflecting current approaches to the work: the Framework, Transcendental, Epistemic, and Therapeutic readings.

This book is a major contribution to the history of analytic philosophy in general and of logical positivism in particular. It provides the first detailed and comprehensive study of Rudolf Carnap, one of the most influential figures in twentieth-century philosophy. The focus of the book is Carnap's first major work: Der logische Aufbau der Welt (The Logical Structure of the World). It reveals tensions within the context of German epistemology and philosophy of science in the early twentieth century. Alan Richardson argues that Carnap's move to philosophy of science in the 1930s was largely an attempt to dissolve the tension in his early epistemology. This book fills a significant gap in the literature on the history of twentieth-century philosophy. It will be of particular importance to historians of analytic philosophy, philosophers of science, and historians of science.

This book is conceived as an introductory text into the theory of syntactic and semantic information, and information flow. Syntactic information theory is concerned with the information contained in the very fact that some signal has a non-random structure. Semantic information theory is concerned with the meaning or information content of messages and the like. The theory of information flow is concerned with deriving some piece of information from another. The main part will take us to situation semantics as a foundation of modern approaches in information theory. We give a brief overview of the background theory and then explain the concepts of information, information architecture and information flow from that perspective.

This radical reading of Wittgenstein's third and last masterpiece, On Certainty, has major implications for philosophy. It elucidates Wittgenstein's ultimate thoughts on the nature of our basic beliefs and his demystification of skepticism. Our basic certainties are shown to be nonepistemic, nonpropositional attitudes that, as such, have no verbal occurrence but manifest themselves exclusively in our actions. This fundamental certainty is a belief-in, a primitive confidence or ur-trust whose practical nature bridges the hitherto unresolved catagorial gap between belief and action.

This 1997 collection of essays addresses topics that are of crucial importance to the lives of us all. Is there a mode of thinking peculiar to human life and its concerns, which is different from and irreducible to scientific rationality? Is historical understanding different from scientific understanding? Do psychology, religion and aesthetics have their own forms of rationality? Can you be rational about human life without being scientific? The contributors address these and related questions, some focusing on the history of the development of the notion of Verstehen, others examining particular areas of discourse and practice.

We inhabit a world of differences - cultural, religious, moral, philosophical. The question that preoccupies the contributors to this volume is whether the fact of difference - plurality - inevitably leads to the conclusion that there cannot be a single truth, even in moral matters. As befits a volume on pluralism, it brings together a wide variety of contributors with different backgrounds and distinctive skills and attitudes. The implications of plurality are examined with regard to religion, morality and philosophy itself, but the essays range widely to consider how we should respond at the social and political levels to the facts of plurality and the claims of the pluralist. No reader will be left in any doubt that the debate about pluralism raises questions that are fundamental not only for philosophical argumentation but for society at large.

Few philosophers in this century have had either Karl Popper's range or his influence, inside and outside philosophy. This collection of essays by fifteen distinguished philosophers, several of whom have been closely associated with Popper and his work, provides a timely assessment of Popper's contributions in a number of key areas: the methodology and philosophy of science; probability and determinism; quantum theory; biology; the theory of evolution; and the theory and practice of politics. The volume offers the specialist and the general reader alike fresh insights into the life and work of one of the twentieth century's most original thinkers.

This 1996 book provides a detailed, systematic reconsideration of the neglected nineteenth-century positivist Auguste Comte. Apart from offering an accurate account of what Comte actually wrote, the book argues that Comte's positivism has never had greater contemporary relevance than now. The aim of the first part of the book is to rescue Comte from the influential misinterpretation of his work by John Stuart Mill. The second part argues that this deep historically-minded concern with the tradition of philosophy for current philosophical practice places Comte in the same camp as such well-known post-positivists as Richard Rorty, Charles Taylor, and Hilary Putnam. Professor Scharff concludes that, even though he was the first positivist, Comte is also the only positivist who retains his relevance today.

Michael Devitt is a distinguished philosopher of language. In this book he takes up one of the most important difficulties that must be faced by philosophical semantics: namely, the threat posed by holism. Three important questions lie at the core of this book: what are the main objectives of semantics; why are they worthwhile; how should we accomplish them? Devitt answers these 'methodological' questions naturalistically and explores what semantic programme arises from the answers. The approach is anti-Cartesian, rejecting the idea that linguistic or conceptual competence yields any privileged access to meanings. This new methodology is used first against holism. Devitt argues for a truth-referential localism, and in the process rejects direct-reference, two-factor, and verificationist theories. The book concludes by arguing against revisionism, eliminativism, and the idea that we should ascribe narrow meanings to explain behaviour.

Supervenience is one of the 'hot discoveries' of analytic philosophy, and this collection of essays on the topic represents an examination of it and its application to major areas of philosophy. The interest in supervenience has much to do with the flexibility of the concept. To say that x supervenes on y indicates a degree of dependence without committing one to the view that x can be reduced to y. Thus supervenience is a relationship that has the potential of replacing the traditional notion of dependence, while performing at least part of the function reductive relationships were supposed to fulfil. Moreover, since it is a topic-neutral concept, supervenience has a wide range of applicability.

Walter Benjamin's work represents one of the most radical and controversial responses to the problems of twentieth-century culture and society. This new interpretation analyzes some of the central enigmatic features of his writing, arguing that they result from the co-presence of religious scepticism and the desire for a religious foundation of social life. Margarete Kohlenbach focuses on the structure of self-reference as an expression of Benjamin's sceptical religiosity and examines its significance in his writing on language, literature and the cinema, as well as history, politics and modern technology.

The eighteenth and nineteenth centuries witnessed a change in the perception of the arts and of philosophy. In the arts this transition occurred around 1800, with, for instance, the breakdown of Vitruvianism in architecture, while in philosophy the foundationalism of which Descartes and Spinoza were paradigmatic representatives, which presumed that philosophy and the sciences possessed a method of ensuring the demonstration of truths, was undermined by the idea, asserted by Nietzsche and Wittgenstein, that there exist alternative styles of enquiry among which a choice is open. The essays in this book examine the circumstances, features, and consequences of this historical transition, exploring in particular new aspects and instances of the inter-relatedness of content and its formal representation in both the arts and philosophy.

This book explores in detail the relation between ontology and ethics in the early work of Ludwig Wittgenstein, notably the "Tractatus Logico-Philosophicus" and, to a lesser extent, the "Notebooks 1914-1916." Self-contained and requiring no prior knowledge of Wittgenstein's thought, it is the first book-length argument that his views on ethics decisively shaped his ontological and semantic thought.
The book's main thesis is twofold. It argues that the ontological theory of the "Tractatus" is fundamentally dependent on its logical and linguistic doctrines: the tractarian world is the world as it appears in language and thought. It also maintains that this interpretation of the ontology of the "Tractatus" can be argued for not only on systematic grounds, but also via the contents of the ethical theory that it offers. Wittgenstein's views on ethics presuppose that language and thought are but one way in which we interact with reality.
Although detailed studies of Wittgenstein's ontology and ethics exist, this book is the first thorough investigation of the relationship between them. As an introduction to Wittgenstein, it sheds new light on an important aspect of his early thought.

It is widely held in contemporary moral philosophy that moral agency must be explained in terms of some more basic account of human nature. This book presents a fundamental challenge to this view. Specifically, it argues that sympathy, understood as an immediate and unthinking response to another's suffering, plays a constitutive role in our conception of what it is to be human, and specifically in that conception of human life on which anything we might call a moral life depends.

Gottlob Frege has exerted an enormous influence on the evolution of twentieth-century philosophy, yet the real significance of that influence is still very much a matter of debate. This book provides a completely new and systematic account of Frege's philosophy by focusing on its cornerstone: the theory of sense and reference. Two features distinguish this study from other books on Frege. First, sense and reference are placed absolutely at the core of Frege's work; the author shows that no adequate account of the theory can avoid analysing the notion of thought that underpins it, or explaining how it has clarified our concept of judgement. Second, the theory is situated within the development of Frege's thought; the author reveals how the theory caused Frege to alter many of his fundamental views. In doing so the author presents a clearer picture of the problems the theory was intended to solve, and delineates more sharply the characteristic features of Frege's philosophy.

Wittgenstein's Metaphysics offers a radical new interpretation of the fundamental ideas of Ludwig Wittgenstein. It takes issue with the conventional view that after 1930 Wittgenstein rejected the philosophy of the Tractatus and developed a wholly new conception of philosophy. By tracing the evolution of Wittgenstein's ideas, Cook shows that they are neither as original nor as difficult as is often supposed. Wittgenstein was essentially an empiricist, and the difference between his early views (as set forth in the Tractatus) and the later views (as expounded in the Philosophical Investigations) lies chiefly in the fact that after 1930 he replaced his early version of reductionism with a subtler version. So he ended where he began, as an empiricist armed with a theory of meaning. This iconoclastic interpretation is sure to influence all future study of Wittgenstein and will provoke a reassessment of the nature of his contribution to philosophy.

Bertrand Russell was a towering intellectual figure of the twentieth century. In his nineties, he dictated more than twelve letters a day. This acclaimed second volume of his letters provides a unique insight into Russell and covers most of his adult life. Russell was a philosophical genius but also an impassioned campaigner for peace and social reform and these letters reveal the astonishing range of his correspondence. There are intense personal letters to his lovers Ottoline Morrell and Colette O'Niel, as well as letters to Niels Bohr, Jean-Paul Sartre, Einstein and Lyndon Johnson, which provide a unique insight into Russell's views on education, war and the Russian Revolution. Invaluable for anyone interested in Russell, these letters also present a fascinating picture of Twentieth century history.
