I argue that the numbering system of the Tractatus lets us see how it was constructed, in two closely related senses of that term. First, it tells us a great deal about the genesis of the book, for the numbering system was used to assemble and rearrange a series of drafts, as recorded in MS 104. Second, it helps us understand the structure of the published book, as cryptically summarized in the opening footnote. I also discuss an unpublished letter from Anscombe to von Wright from 1948 which contains the very first sketch of a tree-structured reading, and what I believe is Stenius’s response to Anscombe’s proposal. The paper critically evaluates previous work on tree-structured readings and contends that we need to read the Tractatus in both the number order used in the published book and the tree order that Wittgenstein used to draft it. It also considers some of the main ways of turning this complex branching structure into a linear, printed text, and so serves as an introduction to the three tree-structured editions of the Tractatus that accompany this paper (the German text, and the translations by Ogden/Ramsey and Pears & McGuinness).

Wittgenstein's 'middle period' is often seen as a transitional phase connecting his better-known early and later philosophies. The fifteen essays in this volume focus both on the distinctive character of his teaching and writing in the 1930s, and on its pivotal importance for an understanding of his philosophy as a whole. They offer wide-ranging perspectives on the central issue of how best to identify changes and continuities in his philosophy during those years, as well as on particular topics in the philosophy of mind, religion, ethics, aesthetics, and the philosophy of mathematics. The volume will be valuable for all who are interested in this formative period of Wittgenstein's development.

In this new introduction to a classic philosophical text, David Stern examines Wittgenstein's Philosophical Investigations. He gives particular attention to both the arguments of the Investigations and the way in which the work is written, and especially to the role of dialogue in the book. While he concentrates on helping the reader to arrive at his or her own interpretation of the primary text, he also provides guidance to the unusually wide range of existing interpretations, and to the reasons why the Investigations have inspired such a diversity of readings. Following closely the text of the Investigations and meant to be read alongside it, this survey is accessible to readers with no previous background in philosophy. It is well-suited to university-level courses on Wittgenstein, but can also be read with profit by students in other disciplines.

Otto Weininger was one of the most controversial and widely read authors of fin-de-siècle Vienna. He was both condemned for his misogyny, self-hatred, anti-semitism and homophobia, as well as praised for his uncompromising and outspoken approach to gender and morality. For Wittgenstein Weininger was a 'remarkable genius'. He repeatedly recommended Weininger's Sex and Character to friends and students and included the author on a short list of figures who had influenced him. The purpose of this new collection of essays is to explore the various ways in which Wittgenstein absorbed and responded to Weininger's ideas. Written by an international team of experts on Wittgenstein and Weininger, the volume is especially timely in the light of recent translations of Weininger's work and will appeal to anyone interested in the history of 20th century philosophy, and the literary and cultural history of fin-de-siècle Vienna.

This edition of G. E. Moore's notes taken at Wittgenstein's seminal Cambridge lectures in the early 1930s provides, for the first time, an almost verbatim record of those classes. The presentation of the notes is both accessible and faithful to their original manuscripts, and a comprehensive introduction and synoptic table of contents provide the reader with essential contextual information and summaries of the topics in each lecture. The lectures form an excellent introduction to Wittgenstein's middle-period thought, covering a broad range of philosophical topics, ranging from core questions in the philosophy of language, mind, logic, and mathematics, to illuminating discussions of subjects on which Wittgenstein says very little elsewhere, including ethics, religion, aesthetics, psychoanalysis, and anthropology. The volume also includes a 1932 essay by Moore critiquing Wittgenstein's conception of grammar, together with Wittgenstein's response. A companion website offers access to images of the entire set of source manuscripts.

Ludwig Wittgenstein was trained as a scientist and an engineer. He received a diploma in mechanical engineering from the Technische Hochschule in Charlottenburg, Berlin, in 1906, after which he did several years of research on aeronautics before turning to the full-time study of logic and philosophy. Hertz, Boltzmann, Mach, Weininger, and William James, all important influences on Wittgenstein, are authors whose work was both philosophical and scientific. The relationship between everyday life, science, and philosophy, is a central concern throughout the course of his writing. He regarded philosophy, properly conducted, as an autonomous activity, a matter of clarifying our understanding of language, or investigating grammar. Wittgenstein thought philosophy should state the obvious as a way of disabusing us of the desire to formulate philosophical theories of meaning, knowledge, language, or science, and was deeply opposed to the naturalist view that philosophy is a form of science. In his later work, Wittgenstein rejected systematic approaches to understanding language and knowledge. Wittgenstein’s answer to the Socratic question about the nature of knowledge is that it has no nature, no essence, and so it is a mistake to think one can give a single systematic answer:If I was asked what knowledge is, I would list items of knowledge and add “and suchlike.” There is no common element to be found in all of them, because there isn’t one.

Wittgenstein’s writings and lectures during the first half of the 1930s play a crucial role in any interpretation of the relationship between the Tractatus and the Philosophical Investigations . G. E. Moore’s notes of Wittgenstein’s Cambridge lectures, 1930-1933, offer us a remarkably careful and conscientious record of what Wittgenstein said at the time, and are much more detailed and reliable than previously published notes from those lectures. The co-authors are currently editing these notes of Wittgenstein’s lectures for a book to be published by Cambridge University Press. We describe the materials that make up Moore’s notes, explain their unique value, review the principal editorial challenges that these materials present, and provide a brief outline of our editorial project

While Wittgenstein wrote unconventionally and denied that he was advancing philosophical theses, most of his interpreters have attributed conventional philosophical theses to him. But the best recent interpretations have taken the form of his writing and his distinctive way of doing philosophy seriously. The 1980s have also seen the emergence of a body of work on Wittgenstein that makes extensive use of the unpublished Wittgenstein papers. This work on Wittgenstein's method and his way of writing are the main themes of this literature review.Section 1 surveys Wittgenstein's conception of philosophical method and its reception. Section 2 is a review of recent work on rule-following and the methodological issues it raises. Section 3 concerns research on the WittgensteinNachlass and its implications for the interpretation of his philosophy.

This is an original, ambitious, and provocative book. It argues that Wittgenstein’s later philosophy can best be understood as a response to two problems that animate post-Kantian idealism and romanticism, drawing primarily on the work of Fichte, Schiller, Schlegel, Hegel, Wordsworth, and Goethe. The first is the metaphilosophical problem of the “critique of critique,” the question of what basis can there possibly be for critical philosophy if Kant’s own appeal to the categories proves unacceptable. The second is the ethical problem of expressive freedom, the question of the relationship between Willkür, volitional freedom, or the power to choose between alternatives, and Wille, rational freedom, that is, free choice informed by rational norms or laws. Eldridge argues that the romantic response to these problems is simultaneously philosophical and literary: to argue that the desperately needed solution must remain beyond our grasp, and to enact this tragic drama of aspiration and its disappointment in writing that continually aspires to yet fails to reach its goal.

The "standard account" of Wittgenstein’s relations with the Vienna Circle is that the early Wittgenstein was a principal source and inspiration for the Circle’s positivistic and scientific philosophy, while the later Wittgenstein was deeply opposed to the logical empiricist project of articulating a "scientific conception of the world." However, this telegraphic summary is at best only half-true and at worst deeply misleading. For it prevents us appreciating the fluidity and protean character of their philosophical dialogue. In retrospectively attributing clear-cut positions to Wittgenstein and his interlocutors, it is very easy to read back our current understanding of familiar distinctions into a time when those terms were used in a much more open-ended way. The paper aims to to provide a broader perspective on this debate, starting from the protagonists’ understanding of their respective positions. Too often, the programmatic statements about the nature of their work that are repeated in manifestoes, introductions, and elementary textbooks have occupied center stage in the subsequent secondary literature. Consequently, I focus on a detailed examination of a turning point in their relationship. That turning point is Wittgenstein's charge, in the summer of 1932, that a recently published paper of Carnap's, "Physicalistic Language as the Universal Language of Science", made such extensive and unacknowledged use of Wittgenstein's own ideas that Wittgenstein would, as he put it in a letter to Schlick, "soon be in a situation where my own work shall be considered merely as a reheated version or plagiarism of Carnap’s." While the leading parties in this dispute shared a basic commitment to the primacy of physicalistic language, and the view that all significant languages are translatable, there was a remarkable lack of mutual understanding between them, and deep disagreement about the nature of the doctrines they disputed. Three quarters of a century later, we are so much more conscious of the differences that separated them than the points on which they agreed that it takes an effort of historical reconstruction to appreciate why Wittgenstein once feared that his own work would be regarded as a pale shadow of Carnap’s.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Taking Wittgenstein at his Word: A Textual StudyDavid SternRobert J. Fogelin. Taking Wittgenstein at his Word: A Textual Study. Princeton-Oxford: Princeton University Press. 2009. Pp. xviii + 181. Cloth, $35.00.This is an excellent book, which should be read widely. It is a short, lucid, and accessible introduction to Wittgenstein’s later philosophy, written by a leading expert. It is the ideal sequel to Saul Kripke’s Wittgenstein on Rules and Private Language on a short list of required readings for a course on Wittgenstein. Part 1 concerns rule following and the conceivability of a private language, while part 2 discusses three topics in his philosophy of mathematics: the status of mathematical expressions, Wittgenstein’s treatment of Cantor on transfinite cardinals, and his approach to logical consistency. There is very little discussion of the secondary literature on any of these topics. Instead, apart from a few prefatory methodological [End Page 147] passages, almost all of the book is devoted to extensive quotations from Wittgenstein’s writing and to close reading of what he says there.Fogelin’s chief aim, to take Wittgenstein at his word, is in a sense a very modest one. Wittgenstein insisted throughout his career that he was not presenting philosophical theses, and that philosophy should not be a matter of defending theses. Indeed, Fogelin explicitly acknowledges that in taking Wittgenstein at his word, he is not presenting “a novel—hitherto unrecognized—way of understanding Wittgenstein’s later philosophy” (xii–xiii). Nevertheless, most interpreters have read Wittgenstein as failing to follow his own methodological precepts, and their interpretations have focused on the theses that they attribute to him. Instead, Fogelin lets “Wittgenstein speak for himself” (xi), not only quoting at length from his writings, but also from Wittgenstein’s “self-commentaries” (xi), passages where Wittgenstein helps us appreciate the philosophical significance he assigns to his words. Crucially, these quotations are held together by a close reading that provides a lucid and perceptive statement of what Wittgenstein is saying there and why, highlighting the intimate connection between Wittgenstein’s philosophical methods and his treatment of key topics in the philosophy of language and mathematics.A leading theme in Fogelin’s book is what he calls Wittgenstein’s “defactoist” approach to rule following. While he does not define this neologism, he does say that it involves “the rejection of appeals to rational processes where philosophers typically have attempted to find or supply them” (41). Furthermore, Fogelin connects it with the central role Wittgenstein gives to natural responses and training, the fact that the kind of training a creature can undergo depends on its natural or instinctive responses and Wittgenstein’s “rejection of the idea that training is merely an external device intended to induce in the trainee a grasp of the correctness, the legitimacy, of what he has been trained to do” (35–36).Although Fogelin never explicitly addresses the crucial question of which texts to draw on in taking Wittgenstein “at his word,” in practice he makes use of a wide range of publications from every stage of Wittgenstein’s career. The Tractatus, written during the First World War, is treated as belonging to an earlier stage of his thought, and some similarities to and differences from his later work are discussed. No such distinctions are drawn between material written in the early 1930s, editors’ reconstruction of lecture notes from the early 1930s and late 1930s, passages from the Philosophical Investigations, assembled in the mid-1940s, the different parts of the Remarks on the Foundations of Mathematics, from the mid-1930s to early 1940s, and selections from On Certainty, dating from the late 1940s and early 1950s. While Fogelin acknowledges that there was some development in Wittgenstein’s views during these years, he puts great weight on passages taken from manuscripts and student lecture notes from the 1930s. For instance, in his crucial opening chapter on rule following, he relies heavily on the words with which Wittgenstein first formulated his paradox of interpretation in the early 1930s (20–21) and on his statement of the connection between meaning and rules in his 1932 lectures (17). While these passages are attractive precisely because they...

The paper maps out and responds to some of the main areas of disagreement over the nature of Wittgenstein’s philosophy: (1) Between defenders of a “two Wittgensteins” reading (which draws a sharp distinction between early and late Wittgenstein) and the opposing “one Wittgenstein” interpretation. (2) Among “two-Wittgensteins” interpreters as to when the later philosophy emerged, and over the central difference between early and late Wittgenstein. (3) Between those who hold that Wittgenstein opposes only past philosophy in order to do philosophy better and those who hold that Wittgenstein aimed to bring an end to philosophy and teach us to get by without a replacement. It is shown that each of these debates depends on some deeply un-Wittgensteinian, and quite mistaken, assumptions. It is concluded that Wittgenstein’s most polished writing, most notably in Philosophical Investigations I §§ 1–425, is best understood as a kind of Pyrrhonism which aims to subvert philosophical theorizing, by means of a polyphonic dialogue. Because this delicate balance between philosophical questions and their dissolution is not achieved in most of his other published and unpublished writings, we should be very cautious when using the theories and methods we find in those other writings as a guide to reading the Philosophical Investigations.

No verão de 1932, Wittgenstein alegou que o artigo recentemente publicado porCarnap “Linguagem Física como Linguagem Universal da Ciência” fez uso extensivo e semmenções das idéias do próprio Wittgenstein. Em uma carta a Schlick, ele se queixou que“em breve estaria em uma situação na qual seu próprio trabalho seria considerado meramentecomo uma versão requentada ou plágio do de Carnap”. Neste artigo, examino arelação entre o artigo de Carnap, posteriormente reimpresso como A Unidade da Ciência, eo tratamento dispensado por Wittgenstein, nos primeiros sete capítulos das ObservaçõesFilosóficas e outros escritos entre 1929-1932, a assuntos relacionados.

Ludwig Wittgenstein is one of the most important, influential, and often-cited philosophers of the twentieth century, yet he remains one of its most elusive and least accessible. The essays in this volume address central themes in Wittgenstein's writings on the philosophy of mind, language, logic, and mathematics. They chart the development of his work and clarify the connections between its different stages. The contributors illuminate the character of the whole body of work by keeping a tight focus on some key topics: the style of the philosophy, the conception of grammar contained in it, rule-following, convention, logical necessity, the self, and what Wittgenstein called, in a famous phrase, 'forms of life'.

Drawing on recent work on the nature of the numbering system of the _Tractatus_ and Wittgenstein’s use of that system in his composition of the _Prototractatus_, the paper sets out the rationale for the online tool called__ __ The University of Iowa Tractatus Map. The map consists of a website with a front page that links to two separate subway-style maps of the hypertextual numbering system Wittgenstein used in his _Tractatus_. One map displays the structure of the published _Tractatus_; the other lays out the structure of the _Prototractatus_. The site makes available the full text of the German and the two canonical English translations.__ __While we envisage the map as a tool that we would like a wide variety of readers to find helpful, we argue that our website amounts to a radically new edition of Wittgenstein’s early masterpiece, with far-reaching implications for the interpretation of that text. In particular, we claim that our visually compelling presentation of the book’s overall structure delivers on Wittgenstein’s cryptic claim in a letter to his publisher that it is the numbers that “make the book surveyable and clear”.
