This Institute's Yearbook for the most part, documents its recent activities and provides a forum for the discussion of exact philosophy, logical and empirical investigations, and analysis of language. This volume holds a collection of papers on various aspects of the work of Rudolf Carnap by an international group of distinguished scholars.​

First Published in 1996. This volume reprints pieces from the Vienna Circle period between the manifesto and the adoption of semantics, as well as two commentaries. During this period, the logical empiricists were the most ambitious and the most confident about the success of their enterprise. The first section consists of four ideological classics, The second section reprints three papers on physicalism. The third section consists of three papers on logic and the fourth on reprints three papers on truth, induction, and confirmation.

The first volume of the Library of Living Philosophers (LLP) appeared in 1939, the brainchild of the late Professor Paul A. Schilpp. Schilpp saw that it would help to eliminate confusion and endless sterile disputes over interpretation if great philosophers could be confronted by their capable philosophical peers and asked to reply. As well as a number of critical essays with the chosen philosopher's replies to each essay, each volume would include an intellectual autobiography and an up-to-date bibliography The LLP series has exceeded even Schilpp's expectations, enabling great philosophers to do more than clarify by extending and elaborating their thoughts. A volume in the Library of Living Philosophers is not merely a commentary on a philosopher's work; it is a critical part of that work.

Rudolf Carnap (1891–1970) is widely regarded as one of the most important philosophers of the twentieth century. Born in Germany and later a US citizen, he was a founder of the philosophical movement known as Logical Empiricism. He was strongly influenced by a number of different philosophical traditions (including the legacies of both Kant and Husserl), and also by the German Youth Movement, the First World War (in which he was wounded and decorated), and radical socialism. This book places his central ideas in a broad cultural, political and intellectual context, showing how he synthesised many different currents of thought to achieve a philosophical perspective that remains strikingly relevant in the twenty-first century. Its rich account of a philosopher's response to his times will appeal to all who are interested in the development of philosophy in the twentieth century.

This book explores the complexity of two philosophical traditions, extending from their origins to the current developments in neopragmatism. Chapters deal with the first encounters of these traditions and beyond, looking at metaphysics and the Vienna circle as well as semantics and the principle of tolerance. There is a general consensus that North-American (neo-)pragmatism and European Logical Empiricism were converging philosophical traditions, especially after the forced migration of the European Philosophers. But readers will discover a pluralist image of this relation and interaction with an obvious family resemblance. This work clarifies and specifies the common features and differences of these currents since the beginning of their mutual scientific communication in the 19th century. The book draws on collaboration between authors and philosophers from Vienna, Tübingen, and Helsinki, and their networks. It will appeal to philosophers, scholars in the history of philosophy, philosophers of science, pragmatists and beyond.

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.

Logical empiricism is a philosophical movement that flourished in the 1920s and 30s in Central Europe and in the 1940s and 50s in the United States. With its stated ambition to comprehend the revolutionary advances in the empirical and formal sciences of their day and to confront anti-modernist challenges to scientific reason itself, logical empiricism was never uncontroversial. Uniting key thinkers who often disagreed with one another but shared the aim to conceive of philosophy as part of the scientific enterprise, it left a rich and varied legacy that has only begun to be explored relatively recently. The Routledge Handbook of Logical Empiricism is an outstanding reference source to this challenging subject area, and the first collection of its kind. Comprising 41 chapters written by an international and interdisciplinary team of contributors, the Handbook is organized into four clear parts: The Cultural, Scientific and Philosophical Context and the Development of Logical Empiricism Characteristic Theses of and Specific Issues in Logical Empiricism Relations to Philosophical Contemporaries Leading Post-Positivist Criticisms and Legacy Essential reading for students and researchers in the history of twentieth-century philosophy, especially the history of analytical philosophy and the history of philosophy of science, the Handbook will also be of interest to those working in related areas of philosophy influenced by this important movement, including metaphysics and epistemology, philosophy of mind and philosophy of language.

Rudolf Carnap and W. V. Quine, two of the twentieth century's most important philosophers, corresponded at length--and over a long period of time--on matters personal, professional, and philosophical. Their friendship encompassed issues and disagreements that go to the heart of contemporary philosophic discussions. Carnap (1891-1970) was a founder and leader of the logical positivist school. The younger Quine (1908-) began as his staunch admirer but diverged from him increasingly over questions in the analysis of meaning and the justification of belief. That they remained close, relishing their differences through years of correspondence, shows their stature both as thinkers and as friends. The letters are presented here, in full, for the first time. The substantial introduction by Richard Creath offers a lively overview of Carnap's and Quine's careers and backgrounds, allowing the nonspecialist to see their writings in historical and intellectual perspective. Creath also provides a judicious analysis of the philosophical divide between them, showing how deep the issues cut into the discipline, and how to a large extent they remain unresolved. Dear Carnap, I enclose a copy of a paper which I am ready to send off for publication. . . . I am anxious to have you look this over as soon as possible, to see whether you have reason to suppose the system contradictory: for it looks dangerous. Dear Quine: I read your paper very carefully and with the highest interest. . . . So far, I do not see any contradiction in the system itself . . . but I share your feeling that the whole looks rather dangerous. Rudolf Carnap and W. V.

Available for the first time in 20 years, here are two important works from the 1920s by the best-known representative of the Vienna Circle. In The Logical Structure of the World, Carnap adopts the position of "methodological solipsism" and shows that it is possible to describe the world from the immediate data of experience. In his Pseudoproblems in Philosophy, he asserts that many philosophical problems are meaningless.
