Au cœur du Tractatus logico-philosophicus est le projet de délimiter « la forme générale de la proposition ». Nous nous intéressons à un versant de ce projet : l’analyse de la notion de vérité. Nous examinons cette analyse et nous identifions quelques-unes de ses conséquences majeures. Puis, nous revenons sur les remarques que fait Wittgenstein sur cette analyse dans les Recherches philosophiques, où l’interrogation sur la possibilité d’une telle analyse sert à remettre en question le projet même (...) du Tractatus.

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)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 63.2 (2002) 345-363 [Access article in PDF] Tractatus Logico-Philosophicus: A "Poem" by Ludwig Wittgenstein David Rozema In the Fall term of 1911 the 22-year-old Ludwig Wittgenstein presented himself to the Cambridge philosopher of mathematics, Bertrand Russell, as a prospective student of philosophy. Wittgenstein had left off his studies as a promising young aeronautical engineer because, in the course of his (...) engineering studies, he had become obsessed with problems in the foundations of mathematics, the very problems Russell himself had tried to solve in his Principia Mathematica, a work he had completed just the year before. Wittgenstein, it seems, did not consider Russell's work to be the end of the matter, and so he had planned a book of his own on the subject. Although this work never materialized, Wittgenstein's interest in philosophy grew under his studies with Russell. And although Wittgenstein's early work in the philosophy of mathematics and logic were the initial impetus for his interest in philosophy, the events of his life soon led him back to the concerns which have always been central to the spirit of philosophy: How ought a man to live? What constitutes the good for man? What sort of life is a worthy or a beautiful one?It is likely that Wittgenstein's concern with these questions was heightened by what he saw in Russell, who followed a notoriously loose way of life outside of his academic studies. 1 If Wittgenstein ever wondered whether or not there was any connection between Russell's philosophical commitments and Russell's way of life, he never directly confronted Russell with the question. Russell was, after all, his benefactor, his mentor, and the source for his initial interest in philosophical problems. 2 Nevertheless, I maintain, Wittgenstein did confront Russell indirectly: he confronted the part of himself that was like Russell and, by attempting [End Page 345] to describe it in writing—the Tractatus Logico-Philosophicus—he discovered its barrenness. Insofar as such an act of writing is elucidatory of a person's soul in what and in how it pictures, it can legitimately be called a kind of poetry, for it bears the essential feature of all poetics: it serves to shape, through catharsis, the passions.Thus, though Wittgenstein neither considered the Tractatus to be a poem nor intentionally wrote it as a poem, it turned out to be a kind of poem in the sense that its form fits its content, both of which, in turn, accurately picture a specific form of life, and the passional result of this poetic construction is (and was, for Wittgenstein) a certain appropriate disdain for the form of life it pictures. This is what I suggest with regard to the Tractatus: it is most helpful and is best read as a poem. I will also try to show that this is how Wittgenstein himself came to think it should be read, which in turn helps to explain why he initially allowed and later continued to allow its publication.What does it mean to read the Tractatus as a poem picturing the form of life implicated by a philosophy like that of Russell's? In this poem Wittgenstein takes the fundamental principles of Russell's philosophy—that all words are signs that stand for objects or kinds of objects and that all meaningful propositions represent a possible arrangement of these objects—and draws out the full-blown implications of these principles. In the last section of the poem Wittgenstein shows the practical consequences of a life lived on these principles, concluding: "Whereof one cannot speak, thereof one must be silent." 3 The two-edged nature of this remark carries the force appropriate to the last line of a poem, for it is both descriptive and imagistic. It describes Wittgenstein's own thought when he realizes that, because of his Russellian philosophical commitments, he has nothing to say with regard to the good, the truth, and the beauty of life; and it is an image of the necessity that a...

"Ludwig Wittgenstein's brief Tractatus Logico-Philosophicus is one of the most important philosophical works of the Twentieth Century, yet it offers little orientation for the reader. The first-time reader is left wondering what it could be about, and the scholar is left with little guidance for interpretation. In Tractatus in Context, James C. Klagge presents the vital background necessary for appreciating Wittgenstein's gnomic masterpiece. Tractatus in Context contains the early reactions to the Tractatus, including the (...) initial reviews written in 1922-1924. And while we can't talk with Wittgenstein, we can do the next best thing-hear what he had to say about the Tractatus. Klagge thus presents what Wittgenstein thought about germane issues leading up to his writing the book, in discussions and correspondence with others about his ideas, and what he had to say about the Tractatus after it was written-in letters, lectures and conversations. It offers, you might say, Wittgenstein's own commentary on the book. Key Features: Illuminates what is at stake in the Tractatus, by providing the views of others that engaged Wittgenstein as he was writing it. Includes Wittgenstein's earlier thoughts on ideas in the book as recorded in his notebooks, letters, and conversations as well as his later, retrospective comments on those ideas. Draws on new or little-known sources, such as Wittgenstein's coded notebooks, Hermine's notes, Frege's letters, Hänsel's diary, Ramsey's notes, and Skinner's dictations. Draws connections between the background context and specific passages in the Tractatus, using a proposition-by-proposition commentary"--. (shrink)

The aim of the paper is to compare the role played by logical analysis in Wittgenstein’s Tractatus logico-philosophicus and Russell’s On Denoting. Whereas in Russell’s work it is an important element of his argument in support of description theory, in his pupil’s it does not function this way. Russell, while analysing various propositions, including descriptions translates them into formal language, indicating that those propositions, despite the appearances, in fact do not denote. Logical analysis shall be a tool (...) decisive in favour of Russell’s thesis. Wittgenstein similarly analyses some troublesome propositions and claims that they are meaningless. The difference is that Russell’s final conclusion is derived from logical analysis, whereas Wittgenstein’s from pure speculation. In Tractatus logico-philosophicus logical analysis is not a method thanks to which the author gets certain result, just as it was the case with his teacher and his On Denoting. In Wittgenstein’s early philosophy logical analysis concerns just a few technical problems connected only to some ideas from Principia mathematica, and not to the main subject of his work, which is the analysis of philosophical theses.

There are historically three main trends in understanding Wittgenstein's Tractatus. The first is the interpretation offered by the Vienna Circle. They read Wittgenstein as arguing that neither metaphysical nor normative propositions have any cognitive meaning, and thus are to be considered nonsense. This interpretation understands Wittgenstein as setting the limits of sense, and prescribing that nothing of substantive philosophical importance lies beyond that line. The second way of reading the Tractatus, which has became popular since the 1950s, is (...) the interpretation which most currently accept as the early Wittgenstein's view; for this reason I refer to it as the 'standard reading.' According to this interpretation, Wittgenstein did not consider metaphysical and ethical discourse as nonsense. Rather, relying upon the distinction between saying [sagen] and showing [zeigen], he meant that these truths cannot be uttered, but instead are only shown. The standard reading can perhaps be best understood in contrast with the third interpretation, dubbed the "resolute reading." The resolute reading takes seriously Wittgenstein's remark at 6.54 that "[m]y propositions are elucidatory in this way: he who understands me finally recognizes them as nonsense [unsinnig]." According to the resolute interpretation, Wittgenstein is not advancing a series of philosophical theses in the Tractatus. Rejecting the distinction characteristic of standard readings, between propositions without sense [sinnlos] and just plain nonsense [unsinnig], these interpreters read Wittgenstein as treating ethical and metaphysical inquiry, as well as a bulk of the doctrines in the text, as nonsense. To them, Wittgenstein did not intend to put forth any theses in the the text. Instead his methodology is therapeutic, similar to the later philosophy. It In this essay I explain each interpretation, and evaluate them in terms of textual and philosophical viability. I conclude by arguing that the biases which exist in the tradition of analytic philosophy substantively temper the interpretation of historical texts, which ultimately leads to the fundamental distinction between these three interpretations.

The author offers a new look at one of the most influential books in the history of philosophy: Ludwig Wittgenstein's "Tractatus Logico-Philosophicus". He presents the Tractatus as expressing the intellectual anxietes of its modernist epoch. The most intruiging but usually unanswered question concerning the Tractatus is why Wittgenstein had to think that only propositions of natural science have meaning. The author reviews the most popular interpretations of the Tractatus and comes to the conclusion that (...) the early Wittgenstein was an ethical subjectivist. With this insight, he solves the tension between Tractarian theses that influenced neopositivism and its mystical part. (shrink)

From Prototractatus to Tractatus Logico-Philosophicus. The author aims to show that in the notebook in which Wittgenstein composed his Tractatus there is no discontinuity between the part published as ‘Prototractatus’ and the last few pages, not published because quite indistinguishable from the final work. The process by which the propositions are combined is homogeneous, following a rigorously top-down strategy: from the six main propositions on the first page to further levels of commentary and, finally, to the (...) more detailed remarks of the last stages. The puzzling chaos of the manuscript derives from his chronological recording of coherent interventions relating to the most different branches of the logic tree. In the first as in the final stage, these interventions were possible thanks to a ‘twin’ text, possibly organized on separate sheets of paper. Therefore, if we read the Tractatus by progressive levels of commentary, rather than sequentially, we then find the same progression of thought developed by Wittgenstein himself during the three years of compiling his manuscript.

This study aims to propose a rational reconstruction of the theory-core ofWittgenstein's Tractatus, in order to bring into prominence its theoreticaland philosophical sources, its epistemological nature and metaphysical significance.The main idea of my approach is that when we take due account of the scientific andphilosophical context of the Tractatus, we see that its central philosophicalinnovation is a new form of metaphysics, namely a structural theory of representation.``I am not interested in constructing a building,so much as in having a (...) perspicuous view of the foundation of possible buildings.''``Und nun sehen wir die gegenseitige Stellung von Logik und Mechanik.''.

This thesis discusses some central aspects of Wittgenstein's conception of language and logic in his Tractatus Logico-Philosophicus and brings them into relation with the philosophies of Frege and Russell. The main contention is that a fruitful way of understanding the Tractatus is to see it as responding to tensions in Frege's conception of logic and Russell's theory of judgement. In the thesis the philosophy of the Tractatus is presented as developing from these two strands of (...) criticism and thus as the culmination of the philosophy of logic and language developed in the early analytic period. Part one examines relevant features of Frege's philosophy of logic. Besides shedding light on Frege's philosophy in its own right, it aims at preparing the ground for a discussion of those aspects of the Tractatus' conception of logic which derive from Wittgenstein's critical response to Frege. Part two first presents Russell's early view on truth and judgement, before considering several variants of the multiple relation theory of judgement, devised in opposition to it. Part three discusses the development of Wittgenstein's conception of language and logic, beginning with Wittgenstein's criticism of the multiple relation theory and his early theory of sense, seen as containing the seeds of the picture theory of propositions presented in the Tractatus. I then consider the relation between Wittgenstein's pictorial conception of language and his conception of logic, arguing that Wittgenstein's understanding of sense in terms of bipolarity grounds his view of logical complexity and of the essence of logic as a whole. This view, I show, is free from the internal tensions that affect Frege's understanding of the nature of logic. (shrink)

The essay has as its main theme proposition 6.5 of Wittgenstein’s Tractatus logico-philosophicus and, in particular, its second paragraph "The riddle does not exist". In the first section, the notion of riddle is compared with that of problem, emphasising, among other things, the great relevance that, for Wittgenstein, the distinction between problems of philosophy and problems of natural science has; in the second, an attempt is made to clarify the meaning that Wittgenstein assigns to the word “riddle”: (...) a riddle would be a question “in the void”, without any “direction”, that is, so to speak, a question that does not know what it is asking. This means that, even if it presents itself as a question, the riddle is a non-question. The third section highlights how the denial that there is the enigma is complementary to the denial, so characteristic of the Tractatus, that there are a priori true thoughts or propositions.

Albert Maslow points out that Wittgenstein dedicated a copy of the Tractatus to Morris Schlick with the following sentence: “ Jeder disese Sätze ist der Ausdruck einer Krankheit ” (Each of this propositions is the manifestation of a disease.) We will try to see some of the treatments to see if the remedy is not, in many cases, worse than the disease. Few philosophical texts have so many material surrounding it as the Tractatus, but and at the same (...) time do maintain such a vast spectrum of interpretations. To the point that one can expect every now and then, exegetical revolutions. Like the political ones, they usually burry the past in its way. An example: the appearance in the 1980s of Wittgenstein's Vienna was a fundamental milestone that showed that it is impossible to dissociate the author from the Viennese intellectual environment. However, attempts have been made to present this new approach as the refutation of the rest, falsely equating the Tractatus with continental philosophy in a book that is really weak in terms of elements of symbolic logic and without any expertise in regard to the philosophy of logic of Frege and Russell, which are essential to understand the context of the concepts in the text of the Tractatus itself and the records of the time. A similar case is the new interpretation that was awarded some ten years later by the North American school: they rightly called attention to the neglect of the essential paradox of the Tractatus of having intended to say what is shown. However, the value of this perspective is lost when the book is treated as the work of a postmodern nihilist, an antimetaphysical dialectician. The same can be said of the interpretation of Raymond Bradley, whose praiseworthy efforts to highlight the Tractarian modal element have resulted in an inadequate Leibnizian framing in his work The Nature of All Being (Bradley, 1992). To show an overview, I would broadly follow the outline of Cerezo (1998), adding and extending his taxonomy a bit. I think Cerezo´s outline is accurate and simple. Cerezo does not take into account contextualist readings or, in any case, it isnt her concern in her Lenguaje y Lógica in Wittgenstein's Tractatus. Let us mention among the ways of reading the Tractatus the empiricist perspectives (in classical version, like Russell, or positivist, like those of Shlick and Carnap ), non-empiricist logicists ( Anscombe, Kenny ), Kantian ( Stenius, Coffa ), metaphysical (in actualist variant, Hacker, or positilist Leibnizian, Bradley), continental (such as Janik and Toulmin ), nihilistic ( Diamond and Conant, Ostrow and his dialectical idea ), and MacGuinn 's elucidatory -ecumenical attempt. David Stern (Stern,1998 ) made a stratification that is not incompatible with the one I point out. 1. The logical-atomistic reading ( logical atomist reading ) of Russell ; 2. The reading of logical positivism ( logical positivist reading ) : with the belligerent antimetaphysical charge ; 3. Metaphysical reading ( metaphysical reading ), like Hacker's, with a logically based idea of metaphysics; 4. The irrationalist reading ( irrationalist reading ) that Toulmin and Janik maintain, for example, or Isidro Reguera, where there is pre-eminence of the religious ethic elements; and 5. therapeutic reading ( therapeutic reading ), which poses it as a kind of infinity joke. We are going to add to the list a reading, which we will call a pathological reading. (shrink)

This paper examines the analysis of judgements of belief that Wittgenstein offers in 5.54–5.5423 of the Tractatus. We offer an interpretation of these paragraphs wich also pays attention to 5.5423, usually forgotten. In our opinion, this interpretation fits with Wittgenstein’s doctrines, and makes clear that such non-genuine propositions are nonsense. These are not, as has sometimes been proposed, the propositions of psychology. In the second part of the article we give a detailed discussion of interpretations of these paragraphs which (...) have been offered previously. (shrink)

Wittgenstein (1993), Derek Jarman’s biopic of the Austrian-born Cambridge philosopher is a fascinating – if perplexing – film. In equal measure aesthetic and didactic, its status is ambiguous, and not only because didacticism in the philosophy of art is often assumed to diminish aesthetic value. Nothing, however, of the film’s aesthetic is depreciated by the intention to instruct. Even if the objective was to teach, the film is also highly aestheticised. Composed of a series of richly theatrical set-pieces, Jarman’s film (...) aspires to a painterly aesthetic. This paper examines the aesthetic and epistemic dimensions of Wittgenstein . The consensus among professional philosophers is that the film, while idiosyncratic and stylised, nevertheless says something important about Wittgenstein’s philosophy. It is as if he has used the project to innovate ways of translating Wittgenstein’s philosophy to aesthetic form. The resultant representational strategies are best understood with reference to the picture theory developed in Wittgenstein’s early philosophy. In the Tractatus Logico - Philosophicus (1922) Wittgenstein characterised the proposition as an articulation of elements that, by virtue of shared logical form, corresponds to the disposition of objects in a possible fact. Under Jarman’s direction, cinematic tableaux are transformed into propositions in the Wittgensteinian sense. In this film, therefore, Jarman has refined his cinematic process into what, following the picture theory, I have called tractarian montage. It is because the philosophy is embedded in the film as a structural component of its form (and not just presented didactically) that Wittgenstein seems oddly right to Wittgensteinian viewers. The aesthetic and epistemic consequences that result from Jarman’s approach are precisely what make the film philosophically interesting – indeed they provide a valuable opportunity to reflect not only on the development of Wittgenstein’s philosophy but also, uniquely, on the relationship between his philosophy and his life.

Ludwig Wittgenstein’s Tractatus logico-philosophicus and Edmund Husserl’s Experience and Judgement (Erfahrung und Urteil) are based on remarkably different conceptual frameworks and methodologies. After analyzing their respective accounts on the foundations of (formal) logic, I map out their common aims and different conclusions. I hold that Husserl and Wittgenstein both use the epistemic necessity of the existence of logical relations among things as an argument against philosophical scepticism, but their different epistemological convictions lead them to decisively diverging accounts (...) of the nature of those relations. Wittgenstein assumes a syntactic correspondence theory of truth, which identifies general logical form as a necessary condition for accurate representation, apparent in the existence of local truth-functions between propositions. As logical form is the (transcendental) necessary condition of every meaningful proposition, he infers that it is itself not representable and without ontological status. Husserl, by contrast, does not draw from a correspondence theory, but from a processual theory of certainty and truth, which offers genetic instead of categorical distinctions between perception and the logical relations apparent in conceptual knowledge. His theory of formal logic ultimately offers a coherent ontology for logical objects, which avoids logical mysticism. (shrink)

In the hundred years since its publication, Wittgenstein’s Tractatus Logico-Philosophicus has become a contemporary classic with the peculiarity that it is surrounded by an aura of mystery: what is really Wittgenstein’s aim in writing the Tractatus, how are we to understand the last two propositions of the Tractatus that enjoin us to detach ourselves from the book itself and keep silent, can the Tractatus be anything other than a positivist and anti-metaphysical treatise, and so (...) on? Here we will argue that the answer to these questions must consider what the ethical meaning of the Tractatus might be and, closely related to that, what its importance is and that of the ineffable in general.

Statements of degree appear to falsify basic doctrines in Tractatus Logico-Philosophicus. I offer a fresh formulation of the challenge and assess a solution proposed on Wittgenstein’s behalf by Sarah Moss. I find that Moss’s proposal fails. The proposal rides in part on novel interpretations of pronouncements by Wittgenstein on the nature of the elementary proposition. I find that the interpretations cannot be sustained but that Moss’s textual case hints at important and overlooked features of the Tractarian program. (...) I develop Wittgenstein’s comparison of propositions to measuring instruments and apply it throughout, showing that it captures philosophical commitments in Tractatus that otherwise tend to slip from view.

In this paper, I propose an assessment of the interpretation of the mathematical notion of probability that Wittgenstein presents in TLP (1963: 5.15 – 5.156). I start by presenting his definition of probability as a relation between propositions. I claim that this definition qualifies as a logical interpretation of probability, of the kind defended in the same years by J. M. Keynes. However, Wittgenstein’s interpretation seems prima facie to be safe from two standard objections moved to logical probability, i. e. (...) the mystic nature of the postulated relation and the reliance on Laplace’s principle of indifference. I then proceed to evaluate Wittgenstein’s idea against three criteria for the adequacy of an interpretation of probability: admissibility, ascertainability, and applicability. If the interpretation is admissible on Kolmogorov’s classical axiomatisation, the problem of ascertainability brings up a difficult dilemma. Finally, I test the interpretation in the application to three main contexts of use of probabilities. While the application to frequencies rests ungrounded, the application to induction requires some elaboration, and the application to rational belief depends on ascertainability. (shrink)

Dans son Introduction au Tractatus de Wittgenstein, Elizabeth Anscombe considérait que le livre avait le défaut d’exclure la proposition « “Quelqu’un” n’est pas le nom de quelqu’un » qu’elle considérait comme évidemment vraie. Ce n’est pas une proposition bipolaire et sa négation n’est pas intelligible. J’examine la question de savoir si elle a raison de dire que le Tractatu s exclut de telles propositions, et je considère son exemple en relation avec d’autres propositions qui, du moins en théorie, n’ont (...) pas de négation intelligible. En considérant le cas particulier de la réponse de Frege à Benno Kerry sur le concept de ‘cheval’, j’essaie de développer une approche de la place que donne la philosophie de Wittgenstein à certains types de proposition qui n’ont pas de négation intelligible.

1921 erschien der Tractatus logico-philosophicus unter dem Titel "Logisch-Philosophische Abhandlung" erstmals; ein Jahr später dann in deutsch-englischer Version unter dem geläufigen Titel. Seit seinem Erscheinen gilt dieses einzige von Wittgenstein selbst veröffentlichte Buch als schwierig und rätselhaft. Für einen Logiker wie Russel schien es eher ein Beitrag zur Mystik als einer zur Logik zu sein. Es ist nicht verwunderlich, daß dieses Buch von Mißverständnissen verfolgt wurde. Erst allmählich wurden die Tiefe, die Bedeutung und die philosophischen Dimensionen des (...) Textes erkennbar. Der Tractatus ist einer der wenigen Schlüsseltexte der zeitgenössischen Philosophie. Seine Bedeutung für Logik, Sprachphilosophie und Metaphysik ist größer, als dies noch vor zwei Jahrzehnten vermutet wurde. Die Beiträge in diesem Band sind mit wenigen Ausnahmen bisher unveröffentlicht. Sie sollen einen Zugang zum Tractatus vermitteln und dessen Verständnis vertiefen. (shrink)

L’article met en avant une persistance de Wittgenstein, de sa première à sa seconde période, dans une conception déflationniste en matière de vérité, conception selon laquelle il n’existe pas de définition explicite ni d’analyse réductive de la vérité. Même si Wittgenstein n’a jamais employé explicitement le terme de « déflationnisme », la tendance au déflationnisme aléthique est caractéristique de sa philosophie du langage. Dans le Tractatus logico-philosophicus, on ne trouve pas une, mais des conditions de vérité pour (...) la proposition élémentaire, la proposition complexe et la proposition tautologique. Le second Wittgenstein, adoptant une approche contextualiste et pragmatique, considère la vérité comme concept dont le sens dépend du contexte concret d’utilisation. Ainsi, la pensée de Wittgenstein présente une certaine continuité dans son approche du problème de la vérité à travers le prisme du déflationnisme. (shrink)

"What one cannot compute, one must poetize." So concludes this remarkable sequence of propositions on the centrality of poetry for what we call cognition. Developed through brief, lucid, and eloquent logical elaborations that are punctuated by incisive readings of a range of poems--Western and non-Western, low culture and high--Poetry and Mind offers to theorists and practitioners of literature, together with logicians and cognitive scientists, a more sophisticated account of the extraordinary regimes of human mental experience. Poetry grants us the ability (...) to move "beyond the limits of thought" and to explore the beyond of cognition. It teaches us to think differently. An elliptic response to Wittgenstein's point of arrival in the Tractatus Logico-Philosophicus, this book is first and foremost an interdisciplinary study of poetry, drawing on literary, philosophical, and scientific traditions. The work conducted on minds and brains over the last decades in psychology, artificial intelligence, and neuroscience cannot be ignored if, as humanists, we are interested in the way we think. Dubreuil thus calls for a constant dialogue with the positive examination of cognition to better situate the normal regimes of thought, as well as to underline the other mental possibilities that literature opens up. Poetry and Mind shows that poetry--a widespread and perhaps universal phenomenon among humans--arises through syntactic structures, cognitive binding, and mental regulations, but that, in going through them, it also exceeds them. The best poems, then, are not only thought experiments but actual thinking experiments for the unthinkable. They expand the usual semantics of natural languages, and singularly deploy the rhetorical armature of speech. Made of iterations and linguistic reorganizations, they exceed their own algorithms and, often, they become reflexive, strange, and cognitively dissonant. They provide detachable, movable, and livable significations to our selves. The literary scope of this book is more than "global": it is uniquely broad and comparative, encompassing dozens of different traditions, oral or written, from all continents, from Ancient times to the contemporary era, with some thirty specific readings of texts, ranging from Sophocles to Gertrude Stein, from Wang Wei to Aimé Césaire, and from cuneiform tablet to rap music. Together, Dubreuil's readings and elaborations offer a major reappraisal of the relations between creation, language and our embodied brains."--Publisher's website. (shrink)

Wittgenstein's Tractatus Logico-Philosophicus can be seen as an attempt at a characterization of a formal language, in which all meaningful scientific and philosophical discourse can be expressed. This characterization is fairly definite in some respects-e.g., he eliminates quantifiers in favour of propositional connectives; however, it is deliberately underdetermined in others-e.g., his choice of non-logical primitives. So much is clear, however: the class of languages so characterized is not fit for expressing non-logical necessity. So it is only consistent (...) that Wittgenstein should deny its existence.At this point two questions arise. Where in the resulting dichotomy between the contingent and the logically true, does Wittgenstein intent to place the actual laws of science? Where can he place them? Our reading of the text yields no conclusive answer to the first question; the second we can answer in the spirit of logicism: certain choices of primitives will make all scientific laws logical.

A milestone in Wittgenstein scholarship, this collection of essays ranges over a wide area of the philosopher's thought, presenting divergent interpretations of his fundamental ideas. Different chapters raise many of the central controversies that surround current understanding of the Tractatus, providing an interplay that will be particularly useful to students. Taken together, the essays present a broader and more comprehensive view of Wittgenstein's intellectual interests and his impact on philosophy than may be found elsewhere.The thirteen chapters treat topics from (...) both periods of Wittgenstein's work: More than half are devoted to his early thought, the Tractatus Logico-Philosophicus of 1921, reflecting a growing interest today among philosophers in reexamining this seminal book, while three chapters treat the Philosophical Investigations, published posthumously in 1953. The remaining chapters discuss such "nonstandard" topics as philosophy of religion, aesthetics, and anthropology.Contents: The Early Wittgenstein and the Middle Russell, Kenneth Blackwell; Frege and Wittgenstein, Michael Dummett; Wittgenstein and the Theory of Types, Hide Ishiguro; The So-called Realism of Wittgenstein's Tractatus, Brian McGuinness; The Logical Independence of Elementary Propositions, David Pears; The Rise and Fall of the Picture Theory, Peter Hacker; The Picture Theory and Wittgenstein's Later Attitude to It, Erik Stenius; Wittgenstein's Early Philosophy of Mind, Anthony Kenny; A Theory of Language?, G.

This paper investigates Wittgenstein’s account of the relation between elementary and molecular propositions (and thus, also, the propositions of logic) in the Tractatus Logico-Philosophicus. I start by sketching a natural reading of that relation – which I call the “bipartite reading” – holding that the Tractatus gives an account of elementary propositions, based on the so-called picture theory, and a different account of molecular ones, based on the principle of truth- functionality. I then show that such (...) a reading cannot be attributed to Wittgenstein, because he holds the view that an explanation of logical complexity is already given by a correct account of the (pictorial) nature of elementary propositions; this is implied in his claim that “an elementary proposition contains all logical constants/operations in itself”. After clarifying Wittgenstein’s notion of an operation from the Notes on Logic to the Tractatus, I finally explain why Wittgenstein claims that an elementary proposition contains all logical operations in itself, and hence why he can be said to provide a unified (and thus not bipartite) account of language and logic.

In the Tractatus Logico-Philosophicus Wittgenstein appeals to clarity when he characterises the aim, task and results of philosophy. In this essay I suggest that his ‘picture theory’ of language implies that clarity has aesthetic significance in philosophical work. Wittgenstein claims that the task of philosophy is to make thoughts clear. In the ‘picture theory’ of thought and language, a thought expressed in language is a proposition with a sense and a proposition is a picture of reality. The (...) question I pose is: how should we construe clarity, if making a thought clear is making clear a picture of reality? Following a close analysis of the picture theory, paying particular attention to the notions of depicting, presenting and mirroring, I conclude that the result of philosophical work – the clarification of propositions – will be pleasurable, inexpressible and intrinsically valuable. For these reasons I suggest that the attainment of a clear thought is an aesthetic experience. (shrink)

Wittgenstein Tractatus Logico-Philosophicus’un sonunda, kendisini anlayan okuyucunun, söylediklerinin saçma olduğunu göreceğini söyler. Eserin bu paradoksu eserle tanışan hemen her okuyucu için bir kafa karışıklığı vesilesidir. Eğer eserde dile getirilenler saçmaysa bunların saçma olduğu da dahil olmak üzere eserin dile getirdiklerini ciddiye almamak gerekir, eğer eser ciddiye alınacaksa söylenenlerin saçma olduğunu kabul etmek gerekir. Eserin bu paradoksunun nasıl ele alınması gerektiğine dair hatırı sayılır bir literatür vardır. Bu çalışmada, Tractatus Logico-Philosophicus’taki bu paradoksun, saçmanın sağaltıcı işleviyle (...) değerlendirildiğinde eseri anlamayı engellemeyeceği fikri savunulacaktır. Bunun için öncelikle genel olarak Resim Kuramı’nın ana hatlarından söz ederek Wittgenstein için saçmanın ne olduğunu anlatacağım. Daha sonra, Wittgenstein için saçmanın işlevinin ne olduğuna dair iyi gerekçelendirildiğini düşündüğüm fikirlerden söz edeceğim. Son olarak, saçmaya işaret edebilmenin ancak saçma ile mümkün olduğunu, Wittgenstein’ın bu yolla yaygın bir yanılgıyı sağalttığını ve dolayısıyla saçmanın sağaltıcı bir işlevi olduğunu iddia edeceğim.
