Ten brilliant essays on logic appear in this collection, the work of one of the world’s best-known authorities on logic. In these thought-provoking arguments and meditations, Nobel Prize winner Bertrand Russell challenges the romantic mysticism of the 19th century, positing instead his theory of logical atomism. These essays are categorized by Russell as "entirely popular" and "somewhat more technical." The former include the well-known title essay plus "A Free Man’s Worship" and "The Place of Science in a Liberal Education"; the (...) latter comprise "On the Notion of Cause" and "Knowledge by Acquaintance and Knowledge by Description," along with other essays written in the cogent and witty style for which their author is justly renowned.

First published in 1973, Sir Anthony Kenny’s classic introduction to Wittgenstein was widely praised for offering a lucid and historically informed account of the philosopher’s core concerns. Kenny's study is also remarkable for demonstrating the continuity between Wittgenstein’s early and late writings. Focusing on Wittgenstein’s philosophy of mind and language, Kenny closely examines the works of the middle years. He exposes apparent conflicts and then goes on to reconcile them, providing a persuasive argument for the unity of Wittgenstein’s thought. This (...) revised edition includes an extensive new introduction in which Kenny outlines developments in Wittgenstein scholarship since the book was first published and assesses Wittgenstein’s influence in the latter part of the twentieth century.

Published in 1903, this book was the first comprehensive treatise on the logical foundations of mathematics written in English. It sets forth, as far as possible without mathematical and logical symbolism, the grounds in favour of the view that mathematics and logic are identical. It proposes simply that what is commonly called mathematics are merely later deductions from logical premises. It provided the thesis for which _Principia Mathematica_ provided the detailed proof, and introduced the work of Frege to a wider (...) audience. In addition to the new introduction by John Slater, this edition contains Russell's introduction to the 1937 edition in which he defends his position against his formalist and intuitionist critics.

Russell's involuted path in the development of his theory of logical types from 1903 to 1910-13 is examined and explained in terms of the development in his early philosophy of the notion of a logical subject vis-a-vis the problem of the one and many; i.e., the problem for russell, first, of a class-as-one as a logical subject as opposed to a class as many, and, secondly, of a propositional function as a single and separate logical subject as opposed to existing (...) only in the many propositions that are its values.

First published in 1946, History of Western Philosophy went on to become the best-selling philosophy book of the twentieth century. A dazzlingly ambitious project, it remains unchallenged to this day as the ultimate introduction to Western philosophy. Providing a sophisticated overview of the ideas that have perplexed people from time immemorial, it is 'long on wit, intelligence and curmudgeonly scepticism', as the New York Times noted, and it is this, coupled with the sheer brilliance of its scholarship, that has made (...) Russell's History of Western Philosophy one of the most important philosophical works of all time. (shrink)

Bertrand Russell is concerned in this book with the foundations of knowledge. He approaches his subject through a discussion of language, the relationships of truth to experience and an investigation into how knowledge of the structure of language helps our understanding of the structure of the world. This edition includes a new introduction by Thomas Baldwin, Clare College, Cambridge.

This is an extensively revised edition of Mr. Quine's introduction to abstract set theory and to various axiomatic systematizations of the subject. The treatment of ordinal numbers has been strengthened and much simplified, especially in the theory of transfinite recursions, by adding an axiom and reworking the proofs. Infinite cardinals are treated anew in clearer and fuller terms than before. Improvements have been made all through the book; in various instances a proof has been shortened, a theorem strengthened, a space-saving (...) lemma inserted, an obscurity clarified, an error corrected, a historical omission supplied, or a new event noted.

In his 1903 Principles of Mathematics, Russell holds that “it is a characteristic of the terms of a proposition”—that is, its “logical subjects”—“that any one of them may be replaced by any other entity without our ceasing to have a proposition”. Hence, in PoM, Russell holds that from the proposition ‘Socrates is human’, we can obtain the propositions ‘Humanity is human’ and ‘The class of humans is human’, replacing Socrates by the property of humanity and the class of humans, respectively. (...) Hence also, in PoM, Russell accepts the doctrine of the unrestricted variable: if we replace a logical subject of a proposition by a variable to yield a propositional function, the range of that variable includes absolutely every entity. For absolutely any entity can be taken as a value of that variable to yield a proposition, true or false. The doctrine of the unrestricted variable is thus incompatible with any type-theoretic metaphysics, according to which only entities of a certain restricted type can replace a logical subject of a given proposition so as to yield another proposition.

Russell's 1913 manuscript Theory of Knowledge was not published until 1984. He supposedly abandoned the main part of the manuscript, while publishing the first six chapters as articles in The Monist, due to Wittgenstein's criticisms of his “multiple relation” analysis of belief. There have been numerous unsuccessful and erroneous attempts to interpret the manuscript, including those of D. Pears and G. Landini. The paper explores the Russell‐Wittgenstein “controversy” and shows the radical way Russell altered his earlier versions of his analysis (...) of belief and the connections the changes had to his new, and very important, analyses of relational order, of truth as correspondence, and of propositions. Russell's analysis of relational order reveals the first recognition by a correspondence theorist of a fundamental problem the correspondence theory faces as well as a long overlooked and unappreciated application Russell made of his theory of definite descriptions.

The paper describes the evolution of russell's theory of judgment between 1910 and 1913, With especial reference to his recently published "theory of knowledge" (1913). Russell abandoned the book and with it the theory of judgment as a result of wittgenstein's criticisms. These criticisms are examined in detail and found to constitute a refutation of russell's theory. Underlying differences between wittgenstein's and russell's views on logic are broached more sketchily.

This paper offers an interpretation of Russell's multiple-relation theory of judgment which characterizes it as direct application of the 1905 theory of definite descriptions. The paper maintains that it was by regarding propositional symbols (when occurring as subordinate clauses) as disguised descriptions of complexes, that Russell generated the philosophical explanation of the hierarchy of orders and the ramified theory of types of _Principia mathematica (1910). The interpretation provides a new understanding of Russell's abandoned book _Theory of Knowledge (1913), the 'direction (...) problems' and Wittgenstein's criticisms. (shrink)

Translation of Frege's 'Über Begriff und Gegenstand' (1892). Translation by Peter Geach, revised by Max Black.

Since the first publication of Insight and Illusion in l972, a wealth of Wittgenstein's writings have become accessible. Accordingly, in this edition Professor Hacker has rewritten six of his eleven original chapters and revised the others to incorporate the new abundant material. Insight and Illusion now fully clarifies the historical backgrounds of Wittgenstein's highly different masterpieces, the Tractatus and the Investigations, and traces the evolution of Wittgenstein's thought. Hacker explains all of Wittgenstein's writings in detail, focusing on his critique of (...) metaphysics, his famous "private language argument," and his account of self-consciousness. (shrink)

G. E. Moore was one of the most interesting and influential philosophers of the first half of the twentieth century. This selection of his writings makes the best of his work once again available, and also includes previously unpublished writings. Moore's first published writings, represented in this collection by his papers "The Nature of Judgment" and "The Refutation of Idealism," contributed decisively to the break with idealism which led to the development of analytic philosophy. Moore went on to develop his (...) own style, which combined a defense of the common sense view of the world with a controversial analysis of the content of this view. Also included is Moore's famous "Proof of an External World," which marked a return late in his career to the critique of idealism. Other papers address perception and important issues in logical theory. The collection ends with three new pieces which illustrate Moore's relationship with Wittgenstein. In these pieces Moore discusses his "paradox" whichso fascinated Wittgenstein; the nature of our knowledge of our own sensations; and Malcolm's views about doubt and knowledge which were themselves inspired by Wittgenstein.

This book explores an important central thread that unifies Russell's thoughts on logic in two works previously considered at odds with each other, the Principles of Mathematics and the later Principia Mathematica. This thread is Russell's doctrine that logic is an absolutely general science and that any calculus for it must embrace wholly unrestricted variables. The heart of Landini's book is a careful analysis of Russell's largely unpublished "substitutional" theory. On Landini's showing, the substitutional theory reveals the unity of Russell's (...) philosophy of logic and offers new avenues for a genuine solution of the paradoxes plaguing Logicism. (shrink)
