Wittgenstein’s Whewell’s Court Lectures contains previously unpublished notes from lectures given by Ludwig Wittgenstein between 1938 and 1941. The volume offers new insight into the development of Wittgenstein’s thought and includes some of the finest examples of Wittgenstein’s lectures in regard to both content and reliability. Many notes in this text refer to lectures from which no other detailed notes survive, offering new contexts to Wittgenstein’s examples and metaphors, and providing a more thorough and systematic treatment (...) of many topics Each set of notes is accompanied by an editorial introduction, a physical description and dating of the notes, and a summary of their relation to Wittgenstein’s Nachlass Offers new insight into the development of Wittgenstein’s ideas, in particular his ideas about certainty and concept-formation The lectures include more than 70 illustrations of blackboard drawings, which underline the importance of visual thought in Wittgenstein’s approach to philosophy Challenges the dating of some already published lecture notes, including the Lectures on Freedom of the Will and the Lectures on Religious Belief.

The contribution reports the inclusion of Ludwig Wittgenstein’s _Nachlass_ into the UNESCO Memory of the World register.

As a celebration of theTractatus100th anniversary it might be worth revisiting its relation to the later writings. From the former to the latter, David Pears recalls that “everyone is aware of the holistic character of Wittgenstein’s later philosophy, but it is not so well known that it was already beginning to establish itself in theTractatus” (The False Prison, 1987). From the latter to the former, Stephen Hilmy’s (The Later Wittgenstein, 1987) extensive study of theNachlasshas helped removing classical misconceptions such (...) as Hintikka’s claim that “Wittgenstein in thePhilosophical Investigationsalmost completely gave up the calculus analogy.” Hilmy points out that even in theInvestigationsone finds the use of the calculus/game paradigm to the understanding of language, such as “in operating with the word” (Part I, §559) and “it plays a different part in the calculus”. Hilmy also quotes from a late (1946) unpublished manuscript (MS 130) “this sentence has use in the calculus of language”, which seems to be compatible with “asking whether and how a proposition can be verified is only a particular way of asking ‘How do you mean?’” Central in this back and forth there is an aspect which seems to deserve attention in the discussion of a semantics for the language of mathematics which might be based on (normalisation of) proofs and/or Hintikka/Lorenzen game-dialogue: the explication of consequences. Such a discussion is substantially supported by the use of the open and searchableThe Wittgenstein Archives at the University of Bergen. These findings are framed within the discussion of the meaning of logical constants in the context of natural deduction style rules of inference. (shrink)

The main goals of this paper are to highlight the new philosophical aspects emerging from Wittgenstein’s Nachlass and to analyze some of the philological questions that should be considered by editors and translators of Wittgenstein’s writings and by scholars of Wittgenstein’s philosophy. There are undoubtedly advantages to be had from exploring Wittgenstein’s Nachlass and this contribution will be focused on them. However, there are also some critical issues to be taken into account. They concern (...) Wittgenstein’s way of writing and doing philosophy as well as the status of Wittgenstein’s manuscripts and the history of their publication. The advantages of investigating Wittgenstein’s movements of thought through and across the Nachlass and the resulting critical issues will be argued from the perspective of direct work editing Wittgenstein (e. g., the edition of two discovered letters of 1934 from Wittgenstein to Sraffa) and through the semantic reconstruction of crucial concepts from Wittgenstein’s philosophy. This reconstruction has been realized by the searching of Wittgenstein’s concepts occurrences and the recording and exploration of the nuances of meaning represented by each occurrence within the project to compose a Wittgenstein dictionary from the Nachlass.

Gordon Baker and I had been colleagues at St John’s for almost ten years when we resolved, in 1976, to undertake the task of writing a commentary on Wittgenstein’s Philosophical Investigations. We had been talking about Wittgenstein since 1969, and when we cooperated in writing a long critical notice on the Philosophical Grammar in 1975, we found that working together was mutually instructive, intellectually stimulating and great fun. We thought that we still had much to say about Wittgenstein’s (...) philosophy, and it seemed to us that misinterpretations of passages in the Investigations were so extensive that it would be worth trying to write a detailed analytical commentary. It is difficult to recapture the excitement of those early days in being among the first to work on the microfilms and, subsequently, on the photocopies of Wittgenstein’s Nachlass. We spent many hundreds of hours poring over the typescripts and the often only semi-legible manuscripts, fascinated and privileged to be able to try to follow the development of the thoughts of a great philosophical genius. We talked endlessly about what we had found in Wittgenstein’s manuscripts and typescripts, and debated how it should be understood. The first fruit of our labours was Wittgenstein – Understanding and Meaning. Its guiding idea was to draw attention to the manner in which Wittgenstein linked the concepts of meaning, understanding and explanation, and so to bypass the connections between meaning, truth and truth-conditions that so fascinated philosophers of the 1970s, and to abandon the red-herring of assertion-conditions and anti-realism. After a hiatus of four years, during which time we wrote a controversial book entitled Frege – Logical Excavations and a polemical book on contemporary philosophy of language – Language, Sense.

Review of Venturinha, Nuno : The Textual Genesis of Wittgenstein’s Philosophical Investigations. Routledge: New York, 2013.

We will discuss a mathematical proof found in Wittgenstein’s Nachlass, a constructive version of Euler’s proof of the infinity of prime numbers. Although it does not amount to much, this proof allows us to see that Wittgenstein had at least some mathematical skills. At the very last, the proof shows that Wittgenstein was concerned with mathematical practice and it also gives further evidence in support of the claim that, after all, he held a constructivist stance, at least during (...) the transitional period of his thought (1929-33).

This volume is dedicated to Wittgenstein's remarks on Frazer's The Golden Bough and represents a collaboration of scholars within philosophy and the study of religion. For the first time, specialized investigations of the philological and philosophical aspects Wittgenstein's manuscripts are combined with the outlook of philosophical anthropology and ritual studies. In the first section of the book Wittgenstein's remarks are presented and discussed in light of his Nachlass and relevant lecture-notes by G.E. Moore, reproduced in this book as facsimiles. (...) The second section deals with the cultural and philosophical background of the early remarks, while the third section focuses specifically on the general problem of understanding as being a main issue of these remarks. The fourth section concentrates on the philosophical development characteristic of the later remarks. Finally, the fifth section reviews Wittgenstein's opposition to Frazer, and the ramifications of his remarks, in light of ritual studies. The book is intended for scholars in philosophy and religious studies, as well as for the general reader with an academic interest in philosophy and the philosophy of religion. (shrink)

Philosopher Ludwig Wittgenstein had an enormous influence on twentieth-century philosophy even though only one of his works, the famous Tractatus Logico-Philosophicus, was published in his lifetime. Beyond this publication the impact of his thought was mainly conveyed to a small circle of students through his lectures at Cambridge University. Fortunately, many of his ideas have survived in both the dictations that were subsequently published, and the notes taken by his students, among them Alice Ambrose and the late Margaret Macdonald, from (...) 1932 to 1935. These notes, now edited by Professor Ambrose, are here published, and they shed much light on Wittgenstein's philosophical development. Among the topics considered are the meaning of a word and its relation to common usage, rules of grammar and their relation to fact, the grammar of first person statements, language games, and the nature of philosophy. This volume is indispensable to any serious discussion of Wittgenstein's work. (shrink)

The edition of the Nachlass from the early thirties by Michael Nedo and the completion of the "Bergen Electronic Edition" (BEE) have provided Wittgenstein scholars with all the material required to investigate the author's philosophical development starting with his auto-criticism of the "Tractatus" and leading to his later views. Wittgenstein's strategy of dictating from his notebooks and cutting up the typescripts to rearrange paragraphs into sequences of remarks is well documented in Nedo's edition and the BEE provides convenient facsimile (...) access to every page Wittgenstein wrote or edited throughout the process. Some researchers have begun to revise received opinions that were based upon the "books" previously published by the trustees. (Hrachovec 2002, 2004, Kientzler 1997, Nyiri 2002, Pichler 2004, Stern 2002) Yet, the scientific community has barely begun to discover the richness and density of the philosophical endeavor manifesting itself in this material. There has, understandably, been an interest to trace the origin of remarks, well-known from the "Philosophical Investigations", providing some background to Wittgenstein's most popular ideas. Various doctrines of what is becoming known as the "middle Wittgenstein" have been noticed, but they have themselves been perceived as more or less consolidated theories. Wittgenstein's editorial activity has been recognized as a hypertextual undertaking avant la lettre, yet there has been insufficient attention to the philosophical impact of these hypertextual strategies themselves. It is all too easy to be caught by someprovisional result captured on a printed page and to overlook the fact that some of its philosophical significance can only be recognized by considering its genesis.

Rush Rhees, Elizabeth Anscombe and Georg Henrik von Wright were Wittgenstein’s literary heirs and edited many posthumous volumes from Wittgenstein’s writings. Their archived correspondence provides unique insights into this editorial work. The selection of letters written by Rhees which is presented here stems from an early phase of his editorial endeavour to shed light on Wittgenstein’s philosophical development between the _TLP_ and the _PI_. The letters were written between 1962 and 1964, in connection with the volume that (...) appeared as _Philosophische Bemerkungen_, and show how Rhees’ understanding of Wittgenstein’s texts developed during editing. They contain some of the central considerations that governed Rhees’ work as Wittgenstein’s literary executor. (shrink)

Building on the unpublished correspondence between Ludwig Wittgenstein's literary executors Rush Rhees, Elizabeth Anscombe and Georg Henrik von Wright, this paper sketches the historical development of different editorial approaches to Wittgenstein's Nachlass. Using the metaphor of a ladder, it is possible to distinguish seven significant “rungs” or “steps” in the history of editing Wittgenstein's writings. The paper focuses particularly on the first four rungs, elucidating how Rhees, Anscombe and von Wright developed different editorial approaches that resulted in significant differences (...) in their editions. The paper sheds light on how these editorial differences are grounded in the editors' divergent understandings of their task. It is suggested that future research may investigate the development of editorial approaches to Wittgenstein's Nachlass as a human story of philosophical inheritance. (shrink)

In my paper I will discuss the difference between Wittgenstein’s notebooks, personal diaries and his so called diaristic remarks scattered throughout the Nachlass. This includes a distinction between his philosophical and his diaristic entries. Secondly, I will outline the editing history of Wittgenstein’s Notebooks 1914 – 1916, his Secret Diaries (Geheime Tagebücher 1914 – 1916), Culture & Value and his diaries of the 1930s (Denkbewegungen). Finally, I will focus on Wittgenstein’s coded remarks (in the wartime notebooks (...) and in his diaristic remarks found in the Nachlass) and then discuss their significance not only in terms of his personal attitude toward life, ethics and religion but also in terms of their role in the context of his philosophizing. In doing so, I will discuss the question of the extent to which Wittgenstein’s method of encoding can be seen as a means for a special type of text, conceived for a sphere not readily accessible to normal language and science – a sphere he avoided talking about in the context of strict philosophical dispute.

The German physicist Heinrich Hertz played a decisive role for Wittgenstein's use of a unique philosophical method. Wittgenstein applied this method successfully to critical problems in logic and mathematics throughout his life. Logical paradoxes and foundational problems including those of mathematics were seen as pseudo-problems requiring clarity instead of solution. In effect, Wittgenstein's controversial response to David Hilbert and Kurt Gödel was deeply influenced by Hertz and can only be fully understood when seen in this context. To comprehend the arguments (...) against the metamathematical programme, and to appreciate how profoundly the philosophical method employed actually shaped the content of Wittgenstein's philosophy, it is necessary to make an intellectual biographical reconstruction of their philosophical framework, tracing the Hertzian elements in the early as well as in the later writings. In order to write Wittgenstein's biography, we have to take seriously the coherence of his thought throughout his life, and not let convenient philosophical ideologies be our guidance in drawing up a “Wittgensteinian philosophy”. To do so, we have to take a second look upon what he actually wrote, not only in the already published material, but in the entire Nachlass. Clearly, this is not easily done, but it is a necessary task in the historical reconstruction of Wittgenstein's life and work. (shrink)

Sixty years after its first edition, there is an increasing consensus among scholars that the work posthumously published as _Philosophical Investigations _represents something that is far from a complete picture of Wittgenstein’s second book project. G.H. von Wright’s seminal research on the _Nachlass_ was an important contribution in this direction, showing that the Wittgenstein papers can reveal much more than the source of specific remarks. This book specifically explores Wittgenstein’s _Philosophical_ _Investigations_ from the different angles of its originary (...) conceptions, including the mathematical texts, shedding new light on fundamental issues in twentieth century and contemporary philosophy. Leading authorities in the field focus on newly published or hitherto unpublished sources for the interpretation of Wittgenstein’s later work and a Wittgenstein typescript, translated for the first time into English, is included as an appendix.

The influence of William James on Ludwig Wittgenstein has been widely studied, as well as the criticism that the latter addresses to the former, but one aspect that has only rarely been focused on is the two philosophers’ use of the image of the flux, stream, or river. The analysis of some notes belonging to Wittgenstein’s Nachlass support the possibility of a comparison between James’ stream of thought, as outlined in the Principles of Psychology, and Wittgenstein’s river-bed (...) of thoughts, presented in On Certainty.

Notes taken by these last four are the basis for the thirty-one lectures in this book.

Between 1937 and 1951 Wittgenstein had numerous philosophical conversations with his student and close friend, Rush Rhees. This article is composed of Rhees’s notes of twenty such conversations — namely, all those which have not yet been published — as well as some supplements from Rhees’s correspondence and miscellaneous notes. The principal value of the notes collected here is that they fill some interesting and important gaps in Wittgenstein ’s corpus. Thus, firstly, the notes touch on a wide range of (...) subjects, a number of which are only briefly addressed by Wittgenstein elsewhere, if at all. The subjects discussed include: explanation, ethics, anarchism, contradiction, psychoanalysis, colour, religion, concepts, classification, seeing-as, evolution, the relation between science and philosophy, and free will, amongst others. Secondly, the notes contain references to, and brief remarks about, philosophers of whom Wittgenstein otherwise says very little, if anything — such as Brentano, Heidegger, Aquinas, and Marx, amongst others. And thirdly, the notes provide us with valuable examples of Wittgenstein ’s use of some key ‘Wittgensteinian’ terms of art which are surprisingly rare in his written works, such as ‘surface-’ and ‘depth-grammar’, and ‘centres of variation’.

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.

David Bohm's interpretation of quantum mechanics yields a quantum potential, Q. In his early work, the effects of Q are understood in causal terms as acting through a real (quantum) field which pushes particles around. In his later work (with Basil Hiley), the causal understanding of Q appears to have been abandoned. The purpose of this paper is to understand how the use of certain metaphors leads Bohm away from a causal treatment of Q, and to evaluate the use of (...) those metaphors. (shrink)
