A comprehensive, systematic, and historical collection of essays on Rudolf Carnap's philosophy and legacy, written by leading international experts. This volume provides a redressing of Carnap's place in the history of analytic philosophy, through his approach to metaphysics, values, politics, epistemology and philosophy of science.

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.

Since the 1930s, philosophy has been divided into two camps: the analytic tradition which prevails in the Anglophone world and the continental tradition which holds sway over the European continent. A Parting of the Ways looks at the origins of this split through the lens of one defining episode: the disputation in Davos, Switzerland, in 1929, between the two most eminent German philosophers, Ernst Cassirer and Martin Heidegger. This watershed debate was attended by Rudlf Carnap, a representative of the Vienna Circle of logical positivists. Michael Friedman shows how philosophical differences interacted with political events. Both Carnap and Heidegger viewd their philosophical efforts as tied to their radical social outlooks, with Carnap on the left and Heidegger on the right, while Cassirer was in the conciliatory classical tradition of liveral republicanism. The rise of Hitler led to the emigration from Europe of most leading philosophers, including Carnap and Cassirer, leaving Heidegger alone on the continent.

Rudolf Carnap's deflationary approach to ontology is once again attracting considerable interest and support. Eleven original essays by leading voices in metametaphysics deepen our understanding of Carnap's contributions to metaontology, and explore how his legacy can be mined for insights into the contemporary debate.

The book consists of a series of chapters on Carnap's ideal of explication as an alternative to the naturalistic conceptions of science, setting it in its historical context, discussing specific cases of explications, and enriching the on-going debate on conceptual engineering and naturalism in analytic philosophy.
