A broad, though not unanimous, consensus among commentators is that the later Wittgenstein subscribes to a redundancy conception of truth. I reject that interpretation. No doubt much depends on what is meant by a redundancy theory. But once even mildly plausible versions of that view are isolated a review of the relevant texts shows that the evidence for that interpretation collapses. Moreover, the redundancy interpretation is at odds with guiding prescriptions in the post‐1932 corpus. Wittgenstein doesn’t hold that truth can (...) be defined or characterized thinly, as redundancy theorists propose, but that it isn’t susceptible to any such generic treatment. (shrink)

In this book Saul Kripke brings his powerful philosophical intelligence to bear on Wittgenstein's analysis of the notion of following a rule.

Wittgenstein's work remains, undeniably, now, that off one of those few philosophers who will be read by all future generations.

We argue that Wittgenstein’s philosophical perspective on Gödel’s most famous theorem is even more radical than has commonly been assumed. Wittgenstein shows in detail that there is no way that the Gödelian construct of a string of signs could be assigned a useful function within (ordinary) mathematics. — The focus is on Appendix III to Part I of Remarks on the Foundations of Mathematics. The present reading highlights the exceptional importance of this particular set of remarks and, more specifically, emphasises (...) its refined composition and rigorous internal structure. (shrink)

Bertrand Russell remains one of the greatest philosophers and most complex and controversial figures of the twentieth century. Here, in this frank, humorous and decidedly charming autobiography, Russell offers readers the story of his life – introducing the people, events and influences that shaped the man he was to become. Originally published in three volumes in the late 1960s, _Autobiography_ by Bertrand Russell is a revealing recollection of a truly extraordinary life written with the vivid freshness and clarity that has (...) made Bertrand Russell’s writings so distinctively his own.

Perhaps the most important work of philosophy written in the twentieth century, the Tractatus Logico-Philosophicus first appeared in 1921 and was the only philosophical work that Ludwig Wittgenstein (1889-1951) published during his lifetime. Written in short, carefully numbered paragraphs of extreme compression and brilliance, it immediately convinced many of its readers and captivated the imagination of all. Its chief influence, at first, was on the Logical Positivists of the 1920s and 30s, but many other philosophers were stimulated by its philosophy (...) of language, finding attractive, if ultimately unsatisfactory, its view that propositions were pictures of reality. Perhaps most of all, Wittgenstein himself, after his return to philosophy in the late 1920s, was fascinated by its vision of an inexpressible, crystalline world of logical relationships. The posthumous publication of other writings has, therefore, only served to reawaken interest in the Tractatus and to illuminate its more neglected aspects. David Pears and Brian McGuinness revised their translation in the light of Wittgenstein's own suggestions and comments in his correspondence with C.K. Ogden about the first translation. In addition, this edition contains the introduction by Bertrand Russell which appeared in the original English translation. (shrink)

pt. 1. The proposition and its sense.--pt. 2. On logic and mathematics.

Truth is one of the most debated topics in philosophy; Wolfgang Kunne presents a comprehensive critical examination of all major theories, from Aristotle to the present day. He argues that it is possible to give a satisfactory 'modest' account of truth without invoking problematic notions like correspondence, fact, or meaning. The clarity of exposition and the wealth of examples will make Conceptions of Truth an invaluable and stimulating guide for advanced students and scholars.

What is the relationship between our perceptions and reality? What is the relationship between the mind and the body? These are questions with which philosophers have grappled for centuries, and they are topics of considerable contemporary debate as well. Hilary Putnam has approached the divisions between perception and reality and between mind and body with great creativity throughout his career. Now, in _The Threefold Cord: Mind, Body, and World,_ he expounds upon these issues, elucidating both the strengths and weaknesses of (...) current schools of thought. With his characteristic wit and acuity, Putnam offers refreshing solutions to some of philosophy's most vexing problems. Putnam first examines the problem of realism: is objective truth possible? He acknowledges the deep impasse between empirical and idealist approaches to this question, critiquing them both, however, by highlighting the false assumption they share, that we cannot perceive the world directly. Drawing on the work of J. L. Austin and William James, Putnam develops a subtle and creative alternative, which he calls "natural realism." The second part of the book explores the mind-body question: is the mind independent of our interactions with the physical world? Again, Putnam critically assesses two sharply antithetical contemporary approaches and finds them both lacking. _The Threefold Cord_ shows the entire mind-body debate to be miscast and draws on the later work of Wittgenstein, once more advancing original views on perception and thought and their relationship with both the body and the external world. Finally, Putnam takes up two related problems--the role of causality in human behavior and whether or not thoughts and sensations have an "existence" all their own. With Putnam's lucid prose and insightful examples, _The Threefold Cord_ loosens the Gordian knots into which philosophy has bound itself over the issue of epistemology. (shrink)

Review of Wittgenstein on Meaning by Colin McGinn.

There is considerable debate amongst philosophers as to the basic philosophical problem Wittgenstein is attempting to solve in _Philosophical Investigations_. In this bold and original work, Meredith Williams argues that it is the problem of "normative similarity". In _Blind Obedience_ Williams demonstrates how Wittgenstein criticizes traditional, representationalist theories of language by employing the ‘master/novice’ distinction of the learner, arguing that this distinction is often overlooked but fundamental to understanding philosophical problems about mind and language. The book not only provides revealing (...) discussions of Wittgenstein’s corpus but also intricate analyses of the work of Brandom, Dummett, Frege, Sellars, Davidson, Cavell and others. These are usefully compared in a bid to better situate Wittgenstein’s non-intellectualist, non-theoretical approach and to highlight is unique features. (shrink)

My paper takes issue both with the standard view that the Tractatus contains a correspondence theory and with recent suggestions that it features a deflationary or semantic theory. Standard correspondence interpretations are mistaken, because they treat the isomorphism between a sentence and what it depicts as a sufficient condition of truth rather than of sense. The semantic/deflationary interpretation ignores passages that suggest some kind of correspondence theory. The official theory of truth in the Tractatus is an obtainment theory – a (...) sentence is true iff the state of affairs it depicts obtains. This theory differs from deflationary theories in that it involves an ontology of states of affairs/facts; and it can be transformed into a type of correspondence theory: a sentence is true iff it corresponds to, i.e. depicts an obtaining state of affairs (fact). Admittedly, unlike correspondence theories as commonly portrayed, this account does not involve a genuinely truth-making relation. It features a relation of correspondence, yet it is that of depicting, between a meaningful sentence and its sense – a possible state of affairs. What makes for truth is not that relation, but the obtaining of the depicted state of affairs. This does not disqualify the Tractatus from holding a correspondence theory, however, since the correspondence theories of Moore and Russell are committed to a similar position. Alternatively, the obtainment theory can be seen as a synthesis of correspondence, semantic and deflationary approaches. It does justice to the idea that what is true depends solely on what is the case, and it combines a semantic explanation of the relation between a sentence and what it says with a deflationary account of the agreement between what the sentence says and what obtains or is the case if it is true.

Bazzocchi disposes the text of the Tractatus in a user-friendly manner, exactly as Wittgenstein's decimals advise. This discloses the logical form of the book by distinct reading units, linked into a fashioned hierarchical tree. The text becomes much clearer and every reader can enjoy, finally, its formal and literary qualities.

Long awaited by the scholarly community, Wittgenstein's so-called Big Typescript is presented here in an en face English-German scholar's edition. Presents scholar's edition of important material from 1933, Wittgenstein's first efforts to set out his new thoughts after the publication of the Tractatus Logico Philosophicus Includes indications to help the reader identify Wittgenstein's numerous corrections, additions, deletions, alternative words and phrasings, suggestions for moves within the text, and marginal comments.

A survey of current evidence available concerning Wittgenstein's attitude toward, and knowledge of, Gödel's first incompleteness theorem, including his discussions with Turing, Watson and others in 1937–1939, and later testimony of Goodstein and Kreisel; 2) Discussion of the philosophical and historical importance of Wittgenstein's attitude toward Gödel's and other theorems in mathematical logic, contrasting this attitude with that of, e.g., Penrose; 3) Replies to an instructive criticism of my 1995 paper by Mark Steiner which assesses the importance of Tarski's semantical (...) work, both for our understanding of Wittgenstein's remarks on Gödel, and our understanding of Gödel's theorem itself.

Ludwig Wittgenstein's philosophical work is informed throughout by a particular broad theme: that the semantic and mentalistic attributes of language and human life are shown by verbal and nonverbal conduct, but that they resist incorporation into the domain of the straightforwardly factual. So argues John Koethe, in contrast to the standard view that Wittgenstein's earlier and later philosophical positions are sharply opposed. According to the received view, Wittgenstein's thinking underwent a radical transformation after the Tractatus, leading him to abandon classical (...) realism and to develop an alternative semantics based on the notion of warranted assertability. Koethe maintains that the thesis that semantic claims are not made true by any facts whatsoever, which was a central part of Wittgenstein's early theory of elementary propositions, was one he continued to develop in his later writings, and that it is perfectly compatible with classical realism. In making his case for the essential continuity of Wittgenstein's thought, Koethe ranges over the entire corpus of the philosopher's writing, and concludes by pointing out connections between Wittgenstein's views and those of several contemporary philosophers, including Nagel, Dennett, Davidson, and Dummett.
