Bertrand Russell and the Nature of Propositions offers the first book-length defence of the Multiple Relation Theory of Judgement (MRTJ). Although the theory was much maligned by Wittgenstein and ultimately rejected by Russell himself, Lebens shows that it provides a rich and insightful way to understand the nature of propositional content. In Part I, Lebens charts the trajectory of Russell’s thought before he adopted the MRTJ. Part II reviews the historical story of the theory: What led Russell to deny the existence of propositions altogether? Why did the theory keep evolving throughout its short life? What role did G. F. Stout play in the evolution of the theory? What was Wittgenstein’s concern with the theory, and, if we can’t know what his concern was exactly, then what are the best contending hypotheses? And why did Russell give the theory up? In Part III, Lebens makes the case that Russell’s concerns with the theory weren’t worth its rejection. Moreover, he argues that the MRTJ does most of what we could want from an account of propositions at little philosophical cost. This book bridges the history of early analytic philosophy with work in contemporary philosophy of language. It advances a bold reading of the theory of descriptions and offers a new understanding of the role of Stout and the representation concern in the evolution of the MRTJ. It also makes a decisive contribution to philosophy of language by demonstrating the viability of a no-proposition theory of propositions.

Wittgenstein’s May–June 1913 critique of Russell’s multiple-relation theory of judgement (or MRTJ) marked a crucial turning point in the lives of two great twentieth-century thinkers. It was also a watershed moment within the history of analytic philosophy itself. Yet scholarly consensus around a satisfactory interpretation of the nature of the critique, the extent of and reasons for its impact on Russell, along with the role it played within Wittgenstein’s development have remained elusive. With these facts in mind, this book aims to accomplish four interrelated goals. The first is to develop a compelling reading of Wittgenstein’s May–June 1913 critique of Russell’s MRTJ. The second is to defend this reading, called the ‘logical interpretation’ (or LI) against its most prominent competitors in the scholarly literature. Third, the book aims to situate Wittgenstein’s critique of the MRTJ and Russell’s reaction to it, within the broader context of each of Wittgenstein’s and Russell’s respective philosophical developments. Fourth and finally, the book aims to introduce students and scholars of early analytic philosophy to, and familiarize them with the historical events, textual evidence, scholarly controversies, letters, notes and diagrams, consideration of which is integral to constructing a plausible reading of Wittgenstein’s objection.

Jos L. Zalabardo puts forward a new interpretation of central ideas in Wittgenstein's Tractatus Logico-Philosophicus concerning the structure of reality and our representations of it in thought and language. He shows the origins of Wittgenstein's picture theory of propositional representation in Russell's theories of judgment, arguing that the picture theory is Wittgenstein's solution to some of the problems that he found in Russell's position. Zalabardo defends the view that, for Wittgenstein, facts in general, and the facts that play the role of propositions in particular, are not composite items, arising from the combination of their constituents. They are ultimate, irreducible units, and what we think of as their constituents are features that facts have in common with one another. These common features have built into them their possibilities of combination with other features into possible situations. This is the source of the Tractarian account of non-actual possibilities. It is also the source of the idea that it is not possible to produce propositions answering to certain descriptions, including those that would give rise to Russell's paradox. Zalabardo then considers Wittgenstein's view that every proposition is a truth function of elementary propositions. He argues that this view is motivated by Wittgenstein's epistemology of logic, according to which we should be able to see logical relations by inspecting the structures of propositions. Finally, Zalabardo considers the problems that we face if we try to extend the application of the picture theory from elementary propositions to truth functions of these.

This volume comprises nine lively and insightful essays by leading scholars on the early philosophy of Ludwig Wittgenstein. They explore three central themes: the relationship between Wittgenstein's account of representation and Russell's theories of judgment; the role of objects in the tractarian system; and Wittgenstein's philosophical method.

Wittgenstein's Tractatus has generated many interpretations since its publication in 1921, but over the years a consensus has developed concerning its criticisms of Russell's philosophy. In Wittgenstein's Apprenticeship with Russell, Gregory Landini draws extensively from his work on Russell's unpublished manuscripts to show that the consensus characterises Russell with positions he did not hold. Using a careful analysis of Wittgenstein's writings he traces the 'Doctrine of Showing' and the 'fundamental idea' of the Tractatus to Russell's logical atomist research program, which dissolves philosophical problems by employing variables with structure. He argues that Russell and his apprentice Wittgenstein were allies in a research program that makes logical analysis and reconstruction the essence of philosophy. His sharp and controversial study will be essential reading for all who are interested in this rich period in the history of analytic philosophy.

In the early twentieth century, an apparently obscure philosophical debate took place between F.H. Bradley and Bertrand Russell. The outcome was momentous: the demise of British Idealism and the rise of analytic philosophy. Stewart Candlish examines afresh this formative period in twentieth-cenutry thought and comes to some surprising conclusions.

This analysis of Wittgenstein's concept of a Spielraum, in which the author approaches the Tractatus Logico-philosophicus both systematically and from the perspective of the history of philosophy and knowledge, opens up a new and important perspective in Wittgenstein research. In establishing unexpected cross-connections between physics, the theory of perception, and logic, Hyder also makes a valuable contribution to the history of 19th century science. In particular, the links he establishes between early sensory physiology and the logicism of Russell and Frege yield a sharper and more plausible account of the notion of a "space" of possible meanings than has hitherto been available in the secondary literature. In showing this notion to be a formal precursor to that of a language game, the study also provides important pointers for the interpretation of Wittgenstein's late work.
