The guiding spirit of the philosophical engagement of Bertrand Russell was to outline a scientific philosophy with the intention of introducing progress and continuity in the subject. With this aim in view, he developed the analytic method which has inspired one of the most influential philosophical currents of this century. Russell's confidence was confirmed by the result of his analysis of perception and physics. This book examines three different theories that Russell used in an effort to provide a lasting solution to the problem of perception and its relation with the external world. Despite the merits of Russell's attempts, the author is convinced that Russell failed to achieve his aim, but that his failure points the way to a better understanding of the nature and purpose of philosophy.

This classic work, first published in 1912, has never been supplanted as an approachable introduction to the theory of philosophical enquiry. It gives Russell's views on such subjects as the distinction between appearance and reality, the existence and nature of matter, idealism, knowledge by acquaintance and by description, induction, truth and falsehood, the distinction between knowledge, error and probable opinion, and the limits and value of philosophical knowledge.

In Russell's Theory of Perception, Sajahan Miah re-examines and evaluates the development of Russell's concept of perception and the relation of perception to our knowledge of the external world. With the introduction of logical construction (in which physical objects are constructed from actual and possible sense-data) Russell's theory of perception seems to become a causal theory with phenomenalist overtones. The book argues that there is a consistency of purpose and direction which motivated Russell to introduce logical construction. The purpose was to strike a compromise between his empiricism and his realism and to establish a bridge between the objects of perception and the objects of physics and common sense.

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.

Theory of Knowledge gives us a picture of one of the great minds of the twentieth century at work. It is possible to see the unsolved problems left without disguise or evasion. Historically, it is invaluable to our understanding of both Russell's own thought and his relationship with Wittgenstein.
