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 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.

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

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.

Tree-Structured Readings of the Tractatus : 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 the original English-language publication of this paper in NWR 11 (the German text, and the translations by Ogden & Ramsey and Pears & McGuinness).

Wittgenstein's principal works, the Tractatus Logico‐Philosophicus and Philosophical Investigations, are each written in such strikingly unconventional ways that it takes considerable effort to translate them into conventional philosophical writing. The most important aspect of Wittgenstein's style for an understanding of his philosophy is his use of multiple voices, and the way he forces his reader to engage with those voices in order to understand him. This chapter provides an outline of the leading macro‐level answers to the question which of Wittgenstein's writings set out his philosophy, and which set out views he rejected. Wittgenstein's method of composition, revision, and rearrangement, leads from the remarks written down in his wartime notebooks, to a manuscript containing several stages of construction of the Prototractatus, and from there to the polished typescript of the Tractatus. The chapter illustrates how to interpret Wittgenstein's remarks without taking a position on questions about texts and style, voice and authorship.

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 mera-mente como 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 ObservaçõesFilosóficase outros escritos entre 1929-1932, a assuntos relacionados.

Ludwig Wittgenstein's treatment of private language has received more attention than any other aspect of his philosophy. Yet, for more than fifty years, a remarkably self-contained exegetical tradition has defined the terms of debate and the principal positions that are discussed. Orthodox interpreters hold that the proof that a private language is impossible turns on showing it is ruled out by some set of systematic philosophical commitments about logic, meaning, and knowledge. Leading candidates for this ground on which the argument depends have included the analysis of concepts, the grammar of our everyday language, the logic of criteria, or the nature of our rule-following, practical activity, or form of life. This article introduces an alternative interpretive tradition, which not only rejects the orthodox methodology, but also rejects the presupposition that Wittgenstein's principal aim is to provide a deductive proof that the idea of a private language leads to contradiction. Finally, it examines some of the leading readings of Philosophical Investigations §258, the passage most frequently discussed by orthodox interpreters.
