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.

SECTIONS 28-46 OF THE Philosophical Investigations contain an elaborate and detailed criticism of a certain misguided conception of ostensive definition, and of the misconceptions of proper names which had characterized logical atomism. At least part of Wittgenstein’s critical discussion appears to be directed at views he himself had earlier adopted, explicitly or tacitly. Other parts are evidently directed at Russell. In section 46 Wittgenstein turns to discuss the ontological counterpart of the notion of the logically proper name—the simple object (...) whose existence is necessary. (shrink)

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.

The paramount role of logic in Wittgenstein’s Tractatus is undeniable and must be obvious to anyone even on a cursory reading. Yet, Wittgenstein's formulations often appear metaphorical when he sketches his ideas on logic and its relation to sentence meaning. Sometimes, they seem more apt to invite loose philosophical associations than pinning down rigorously technical details. This impression notwithstanding, the Tractatus still offers one of the deepest philosophical accounts of modern logic and it does so precisely through (...) its suggestive exposition. It is, in particular, the spatial analogies, Wittgenstein’s ‘logical place’ and ‘logical space’, which are crucial in this connection, and while they carry a structure that is specific for Wittgenstein’s own conception of logic, they are sufficiently general to accommodate also alternative conceptions of logic. Thus, even 100 years after its first publication, Wittgenstein’s Tractatus remains a source of inspiration and a highly valuable one for the philosophy of logic. (shrink)

An essay examining logical atomism as it arises in Russell and the early Wittgenstein.

In the preface to this book Stephen Toulmin recalls how Wittgenstein's later work appeared to his English students "as unique and extraordinary as the Tractatus had appeared to Moore." "Meanwhile," he recalls, "for our own part, we struck Wittgenstein as intolerably stupid, and he was sometimes in despair about getting us to grasp what he was talking about." Toulmin suggests that this "mutual incomprehension" was due to a "culture clash: the clash between a Viennese thinker whose whole mind (...) had been formed in a post-Kantian environment, and an audience of students who came to him with attitudes and preoccupations shaped by the neo-Humean empiricism of Moore, Russell and their associates." Engel's book is meant primarily to show that Wittgenstein's thought grows out of the Kantian philosophy, but not that it is simply derived from Kant. Rather, according to Engel, Wittgenstein was the first to see the full value of the insights of Kant and Schopenhauer. Engel bases his argument on the Blue Book. According to Engel the argument of the Blue Book comprehends two divergent theories of the origin of metaphysics. These two theories are represented in Engel's book by Ayer and Lazerowitz. For Ayer metaphysics is grounded in the inherently deceptive character of language; and the way to overcome metaphysics is but to be attentive to language. Lazerowitz, on the other hand, attempts to explain why it is that language is deceptive. Lazerowitz's argument as presented by Engel requires as a premise the proposition that the deceptions of language are not that intrinsically difficult to see through, or that metaphysical arguments are obviously "innovations." And therefore the origin of metaphysics must be sought outside of the structure of language. Lazerowitz locates the root of metaphysics in the passions, specifically, in fear--in the fear of change which is ultimately the fear of death. Engel sees each of these positions as in its way legitimate but essentially partial. Wittgenstein's thought is thus more profound than that which is derived from it. It is precisely this awareness of the necessity for both kinds of explanation that Wittgenstein, according to Engel, inherited from the tradition of Kantian metaphysics: in the first Critique's seeking both to account for the impossibility of metaphysics while, at the same time, arguing for the necessity of metaphysics as a natural disposition or arguing for the necessity of a "will to metaphysics." While Engel's argument is not as clear or thorough as it ought to be, his thesis, that Wittgenstein's work is not simply a "repudiation of our philosophical tradition, but rather is its proper twentieth-century continuation," is--in the main--convincing. The book is worth reading.--J. W. S. (shrink)

Using the later Levinas as a point of departure, this article tries to provide an account of the ethics of Wittgenstein's Tractatus . Although there has not been written much on this topic, there seems to be an increasing awareness among philosophers that there are interesting points of convergence between Levinas and the early Wittgenstein. In contrast to most (if not all) other accounts of the relation, however, this article argues that the truly significant convergence emerges only when (...) one abandons the received interpretation of the early Wittgenstein, and instead opts for something more akin to the ‘new Wittgenstein’ interpretation introduced by Cora Diamond and James Conant, among others. On the received interpretation, Wittgenstein places ethics in a realm of ineffable being and truth, and thus remains within what Levinas calls ontology. But on Conant's and Diamond's reading of Wittgenstein, there really are no profound ethical truths that we cannot state, but only ‘show’; all the sentences of the Tractatus that appear to claim otherwise are ultimately completely nonsensical. This article argues that the Tractatus has an ‘ethical point’ in a quite Levinasian sense, precisely because of the way it unveils its sentences as utterly nonsensical; for this can be seen as a Wittgensteinian attempt to ‘unsay’ the ‘said’, in order to let the ‘saying’ itself be heard. Key Words: ethics • Emmanuel Levinas • nonsense • the Other • said • saying • Ludwig Wittgenstein. (shrink)

Scott Soames’s two volume work Philosophical Analysis in the Twentieth Century1 won the American 2003 Award for Best Professional/Scholarly Book in Philosophy. It has been said to be ‘a marvellous introduction to analytic philosophy’, to deliver much ‘solid information on this dense and difficult subject’, and it has been predicted to become the standard history of twentieth-century analytic philosophy.2 Professor Soames writes clearly and candidly. At the beginning of each volume he delineates his objectives and leitmotivs. He is concerned with (...) the development of analytic philosophy from 1900 to 1975. He aims ‘to explain what the most important analytic philosophers thought and why they thought it’ (I, xi). His method is ‘to provide clear, focused and intense critical examinations of some of the most important and representative works of each major philosopher discussed. ... to provide enough detail to allow one to understand and properly evaluate the main philosophical developments of the period’ (I, xvii). A book with such laudable objectives, which holds out such high promises, and which is predicted to become the standard history of modern analytic philosophy merits careful study and considered judgement. The questions that I shall pose are dictated by the author’s aims and methods. (i) Does Soames provide an illuminating overview of analytic philosophy from 1900 to 1975? (ii) Does he correctly explain what the most important analytic philosophers thought and why they thought it? (iii) Does he select ‘some of the most important and representative works of each major philosopher discussed’? (iv) Does he properly evaluate the main developments of the period? II The broad picture Soames paints is as follows. Analytic philosophy commenced with Moore’s defence of common sense, and was continued by Russell, whose theory of descriptions, conception of analysis, logicism and logical atomism are recounted. He was followed by Wittgenstein, who argued in the Tractatus that philosophical problems arise solely from misunderstandings of language and defended the view that all necessary truths are a priori, analytic, and hence true in virtue of the meanings of words..

This is an indispensable volume for the study of Wittgenstein's philosophy and is also, in a certain manner, an introduction to many of the problems which have beset Anglo-American philosophy as a whole since the first appearance of the Tractatus. The thirty articles, reviews, and notes are arranged chronologically—with the exception of Ryle's quasi-expository article which begins the volume—and run from Ramsey's 1923 review to David Keyt's 1964 article, "Wittgenstein's Picture Theory of Language." All the articles (...) are complete with the exception of a review of Stenius' book by Shwayder. A comprehensive bibliography of items relating to the Tractatus is included as is an index of references to the propositions of the Tractatus. Credits for the Zemach and second Keyt articles were omitted from the proper place, evidently by mistake; they are given in the bibliography. Wittgenstein's own "Some Remarks on Logical Form" is included—with a proxy disclaimer as to its relevance by Wittgenstein through Anscombe. Also included is a satirical "Epistle" written by Julian Bell in 1932. The book as a whole is a model example of what a critical anthology should be.—E. A. R. (shrink)

The so-called "Big Typescript" is Wittgenstein's first attempt to publish in a book his collected thoughts since his return to Cambridge and to philosophical writing, thus correcting the "serious errors" (Wittgenstein) of his early work. Among the texts in Wittgenstein's estate, the "Big Typescript" is the one that, next to the "Logisch-Philosophische Abhandlung" (the "Tractatus") of 1918, appears to be the most "finished", with a table of contents structured in chapters and sections. It is, however, a fragment, (...) without either title, motto or conclusion. To Wittgenstein, it was important "that the thoughts in [the book] should progress from one subject to another in well-ordered consecutiveness." It is precisely this structure of the "Big Typescript", though ultimately rejected by Wittgenstein, which constitutes the immeasurable value of the text for the study of and as an introduction to Wittgenstein's thinking.

Wittgenstein's Tractatus has generated many interpretations since its publication in 1921, but over the years a consensus has developed concerning its criticisms of Russell's philosophy. In Wittgenstein's Apprenticeship with Russell, Gregory Landini draws extensively from his work on Russell's unpublished manuscripts to show that the consensus characterises Russell with positions he did not hold. Using a careful analysis of Wittgenstein's writings he traces the 'Doctrine of Showing' and the 'fundamental idea' of the Tractatus to Russell's (...) logical atomist research program, which dissolves philosophical problems by employing variables with structure. He argues that Russell and his apprentice Wittgenstein were allies in a research program that makes logical analysis and reconstruction the essence of philosophy. His sharp and controversial study will be essential reading for all who are interested in this rich period in the history of analytic philosophy. (shrink)

Understanding Wittgenstein's Tractatus provides an accessible and yet novel discussion of all the major themes of the Tractatus. The book starts by setting out the history and structure of the Tractatus. It then investigates the two main dimensions of the early Wittgenstein's thought, corresponding to the division between what language can say by means of its propositions and what language can only show. It goes on to discuss picture theory, logical atomism, extensionality, truth-functions and (...) truth-operations, semantics, metalogic and mathematics, solipsism and value, metaphysics, and finally, Wittgenstein's idea of the duty of maintaining silence. Frascolla also proposes a new interpretation of the ontology of the Tractatus. Based on the identification of objects with qualia, the argument put forward in the book challenges the currently prevalent ideas of the ‘New Wittgenstein'. The paradoxical nature of the Tractatus itself, and the theme of "throwing away the ladder", are thus revisited in a new key. _Understanding Wittgenstein's Tractatus_ is essential reading for anyone wishing to further their insight into one of the most influential works of twentieth-century philosophy. (shrink)

Discussion of Wittgenstein's Tractatus is currently dominated by two opposing interpretations of the work: a metaphysical or realist reading and the 'resolute' reading of Diamond and Conant. Marie McGinn's principal aim in this book is to develop an alternative interpretative line, which rejects the idea, central to the metaphysical reading, that Wittgenstein sets out to ground the logic of our language in features of an independently constituted reality, but which allows that he aims to provide positive philosophical insights (...) into how language functions. McGinn takes as a guiding principle the idea that we should see Wittgenstein's early work as an attempt to eschew philosophical theory and to allow language itself to reveal how it functions. By this account, the aim of the work is to elucidate what language itself makes clear, namely, what is essential to its capacity to express thoughts that are true or false. However, the early Wittgenstein undertakes this descriptive project in the grip of a set of preconceptions concerning the essence of language that determine both how he conceives the problem and the approach he takes to the task of clarification. Nevertheless, the Tractatus contains philosophical insights, achieved despite his early preconceptions, that form the foundation of his later philosophy. -/- The anti-metaphysical interpretation that is presented includes a novel reading of the problematic opening sections of the Tractatus, in which the apparently metaphysical status of Wittgenstein's remarks is shown to be an illusion. The book includes a discussion of the philosophical background to the Tractatus, a comprehensive interpretation of Wittgenstein's early views of logic and language, and an interpretation of the remarks on solipsism. The final chapter is a discussion of the relation between the early and the later philosophy that articulates the fundamental shift in Wittgenstein's approach to the task of understanding how language functions and reveal the still more fundamental continuity in his conception of his philosophical task.

When in May 1930, the Council of Trinity College, Cambridge, had to decide whether to renew Wittgenstein's research grant, it turned to Bertrand Russell for an assessment of the work Wittgenstein had been doing over the past year. His verdict: "The theories contained in this new work . . . are novel, very original and indubitably important. Whether they are true, I do not know. As a logician who likes simplicity, I should like to think that they are not, (...) but from what I have read of them I am quite sure that he ought to have an opportunity to work them out, since, when completed, they may easily prove to constitute a whole new philosophy." "[ Philosophical Remarks ] contains the seeds of Wittgenstein's later philosophy of mind and of mathematics. Principally, he here discusses the role of indispensable in language, criticizing Russell's The Analysis of Mind . He modifies the Tractatus 's picture theory of meaning by stressing that the connection between the proposition and reality is not found in the picture itself. He analyzes generality in and out of mathematics, and the notions of proof and experiment. He formulates a pain/private-language argument and discusses both behaviorism and the verifiability principle. The work is difficult but important, and it belongs in every philosophy collection."--Robert Hoffman, Philosophy "Any serious student of Wittgenstein's work will want to study his Philosophical Remarks as a transitional book between his two great masterpieces. The Remarks is thus indispensible for anyone who seeks a complete understanding of Wittgenstein's philosophy."--Leonard Linsky, American Philosophical Association. (shrink)

The Enchantment of Words is a study of Wittgenstein's early masterpiece, the Tractatus Logico-Philosophicus. Recent years have seen a great revival of interest in the Tractatus. McManus's study of the work offers novel readings of all its major themes and sheds light on issues in metaphysics, ethics and the philosophies of mind, language, and logic.

Wittgenstein finished part 1 of the Philosophical Investigations in the spring of 1945. From 1946 to 1949 he worked on the philosophy of psychology almost without interruption. The present two-volume work comprises many of his writings over this period. Some of the remarks contained here were culled for part 2 of the Investigations ; others were set aside and appear in the collection known as Zettel . The great majority, however, although of excellent quality, have hitherto remained unpublished. This bilingual (...) edition of the Remarks on the Philosophy of Psychology presents the first English translation of an essential body of Wittegenstein's work. It elaborates Wittgenstein's views on psychological concepts such as expectation, sensation, knowing how to follow a rule, and knowledge of the sensations of other persons. It also shows strong emphasis on the "anthropological" aspect of Wittgenstein's thought. Philosophers, as well as anthropologists, psychologists, and sociologists will welcome this important publication. (shrink)

If we consider Wittgenstein's career as a whole, it appears that he wrote more on the philosophy of logic and mathematics than any other subject. Yet his writings on these subjects have exerted little influence. Indeed, the tide of response to Remarks on the Foundations of Mathematics, which contains the bulk of his latest views of mathematics, has been for the most part overwhelmingly negative. Given his later emphasis on the context-bound character of language, mathematics and logic--where language apparently (...) operates in an maximally precise, clear and general way--represent two of the most difficult cases for Wittgenstein to confront. My thesis aims to defend Wittgenstein from the charges of benighted arrogance traditionally levelled against him. I argue that Wittgenstein's later discussions of mathematics form a central part of a larger philosophical project, internally related to Philosophical Investigations and shaping in specific ways Wittgenstein's reaction to both scepticism and accounts of the nature of logical and mathematical truth. I see Wittgenstein criticizing the unreflective use of mathematical tools in philosophy, not offering a competing philosophy of mathematics. ;Too few of Wittgenstein's readers have been willing to offer detailed exegesis of his writing . This has made it difficult to understand how the aphoristic style of his late writing bears on the philosophical problems being discussed. On my view, the quality of Wittgenstein's writing is intrinsic to his later conception of the nature of logic, mathematics and philosophy. Line by line engagement with his texts is thus imperative in order to achieve an understanding of his philosophical objectives and criticisms. My dissertation offers as a paradigm of such reading a detailed exegesis and criticism of the opening five sections of Remarks on the Foundations of Mathematics. ;I briefly explore in some detail the origin and genesis of Wittgenstein's interest in rule-following, from its roots in the Tractatus's conception of logical syntax. This background illuminates Wittgenstein's later conception of logical truth and his criticisms of Frege's and Russell's arguments for logicism. To explore these criticisms, I focus on Wittgenstein' s discussions of the Frege-Russell definition of "Number" in "logical" terms. Placed in their appropriate philosophical and historical context, Wittgenstein's seemingly outrageous remarks about the nature of proof, mathematical logic and the foundations of mathematics do not simply betray his ignorance. Nor do they commit him to a revisionist attitude toward mathematical practice. Rather, they raise fundamental questions about the philosophical presuppositions lying behind attempts to bring particular mathematical results to bear in philosophy. (shrink)

Carnap’s Logical Syntax of Language was one of the first philosophical applications of the results in logical metatheory that appeared in the early 1930s. In using these results, Carnap claimed that he stood in general agreement with Wittgenstein’s Tractatus, but had overcome the limits on the scope of logic that Wittgenstein believed he had found. I argue that Carnap had in fact presupposed a conception of linguistic meaning fundamentally at odds with that presented in the Tractatus, (...) and that he had no non-questioning-begging way of defending this presupposition. As a result Carnap had not so much extended the conception of language and logic present in the Tractatus as he had fundamentally reoriented it, and this reorientation continued with Carnap’s later move to semantics.

This short book comprises “four largely self-contained studies … unified by a common interpretive approach”, the “investigation of the historical development of … Wittgenstein’s early philosophy”. Proops applies this historical approach to Wittgenstein’s conception of logic, his critique of “logical assertion,” his “picture theory” of language, and his discussion of the justification of deduction. He endeavors to “bring out how Wittgenstein develops his views … as foils to the positions developed by Frege and Russell”, arguing that “it is not (...) Frege but Russell whose work provides the most important background for … the Tractatus”. (shrink)

The ontology of the "tractatus", In terms of which objects are characterized as propertyless simples, Is coherent provided wittgenstein is not mistakenly taken to be a constructive atomist building complexes from simples. A geometrical model is given to illustrate this. It is also shown that an ontology like that of the "tractus" removes much of the conceptual puzzlement of modern particle physics and has implications for current debates about realism, Possible worlds and rigid designators.

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.

It is argued that the Tractatus Project of Logical Atomism, in which the world is conceived of as the totality of independent atomic facts, can usefully be understood by conceiving of each fact as a bit in logical space. Wittgenstein himself thinks in terms of logical space. His elementary propositions, which express atomic facts, are interpreted as tuples of co-ordinates which specify the location of a bit in logical space. He says that signs for elementary (...) propositions are arrangements of names. Here, the names are understood as numerical symbols specifying coordinates. It is argued that, using this approach, the so-called colour-exclusion problem, which was Wittgensteins reason for abandoning the Tractatus, is in fact soluble. However, if logical space is a continuum then some coordinates will need to be expressed by numerical symbols that are infinite in size. How is this to be understood in Tractatus terms? It is shown that, in the Tractatus, Wittgenstein did recognise the possibility of infinite propositions and sentences expressing them. At first sight his approach to infinite sentences, and the approach of the present paper, seem to differ, but it is argued that the difference is superficial. Finally, we address the question of whether Logical Atomism is viable and this raises issues concerning its relationship to natural science. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Scale Theory: A Nondisciplinary Inquiry by Joshua DiCaglioS. Scott GrahamScale Theory: A Nondisciplinary Inquiry. By Joshua DiCaglio. Minneapolis: University of Minnesota Press, 2021. 349 pp. Paperback: $30.00. ISBN: 978-1-5179-1207-9.Scale Theory embodies its title in every possible way. It offers both a deep dive into and a 10,000-foot view of scale, scalar thinking, and the role of scale in scientific inquiry. The subtitle, A Nondisciplinary Inquiry, is no less (...) apt. Author Joshua DiCaglio blends insights from rhetoric, philosophy, literary studies, and mysticism to create a novel account of scalar thinking. In so doing, he weaves together detailed thought experiments, the work of Gregory Bateson, and Philip K. Dick's account of an extraterrestrial communication he received while under the influence of anesthesia. Provocatively, Scale Theory treats these diverse intellectual resources as coequal contributors to an emerging theory of scale and scalar thinking. Within this nondisciplinary framework, the book is devoted to advancing two primary theses: (1) Notions of scale are undertheorized in science studies and related strands of new materialisms; and (2) Proper attention to questions of scale within these theoretical traditions should prompt a more thoughtful reconsideration of the merits of mystic holism. Ultimately, Scale Theory makes a compelling case for the first thesis and advances inquiry usefully in this area. With respect to the second thesis, DiCaglio refers to a certain academic "allergy" to holism (99), and I must confess I share this allergy. That said, I assume readers already predisposed favorably toward mystic holism are likely to find Scale Theory's attention to the second thesis thoughtful and engaging.Scale Theory is organized into three distinct parts. Part 1, "Algorithms for a Theory of Scale," presents three interrelated thought experiments that call upon readers to imagine themselves at various distances and vantage points with respect to several objects of interest. Part 1 is stylistically [End Page 388] Wittgensteinian. Like the Tractatus-Logico Philosophicus (Wittgenstein 2013) or Latour's "Irreductions," (1993), the thought experiments unfold as a series of numbered and nested propositions, each postulating or interrogating an emerging concept in DiCaglio's theory of scale. Part 2, "Configurations for a Theory of Scale," returns the reader to more familiar styles of prose, providing a sort of review of the relevant literature and its relationship to the insights of the thought experiments. Finally, part 3, "Rhetorical Technologies for a Theory of Scale," reflects on the twin marginalizations of rhetoric and mysticism in mainstream Western academia and argues for a new embrace of disembodied inquiry.The aforementioned thought experiments of part 1 outline DiCaglio's theories of scale, scalar thinking, and scalar analysis. The discussion makes extensive use of visual and cinematic metaphors to aid the reader's consideration of scalar questions. Ultimately, DiCaglio posits that scale is a function of the relationship between the "'being' of phenomena" and "the one who is measuring" (8). He argues, therefore, that "scale functions at a level above ontology and epistemology: scale is a means of orienting yourself both to experience and the being of things" (8). In making this argument, Scale Theory reflects on a range of scientific practices that require gradients of scale. Microscopy, telescopy, and simulations all provide scientists with tools to escape the mundane scales of embodied human experience. DiCaglio argues that "science must always find itself grouping things together, speaking of species, types, systems, and so on which exist on a different logical type than the individual encounters that make up these groups" (41). The taxonomic activities of scientific practice require shifts in scale to account for kingdoms, phyla, orders, genera, species, and all manner of nonbiological analogs.Within this framework, scale functions as a sort of meta-ontology that allows objects to be provisionally identified and delineated. Echoing Bateson, DiCaglio argues thatIn order for any thing to be said to exist whatsoever, a differential must exist out of which a difference can be discerned. Every differential occurs on some scale at which a fluctuation or movement is able to make a difference. If one goes to a smaller scale, any given differential is no longer able to be used to register a difference.(51... (shrink)

Meu objetivo aqui é o de abordar os escritos iniciais de Wittgenstein com base na tradição do misticismo filosófico. O benefício de minha leitura se deve ao fato de permitir uma certa clarificação no que tange a determinadas passagens obscuras, além de trazer à tona perspectivas inexploradas concernentes ao período inicial do autor; fase esta que, em minha opinião, ainda requer um nível de escrutínio adicional.Entendo que especialmente no caso do Tractatus, Wittgenstein não incida no místico por conta de (...) uma limitação da perquirição lógico-linguística relacionada a determinadas regiões do conhecimento, pelo contrário. Irei sugerir que a aplicação da lógica ocorre com o propósito de estabelecer o escopo do místico. Portanto, o que proporei em seguida é a tentativa de desenvolvimento de uma “interpretação mística” emrelação aos escritos iniciais do autor.AbstractMy goal here is to approach Wittgenstein’s initial writings based on the tradition of philosophical mysticism. The benefit of my reading is that it will allow some clarification in regard to obscure passages and still unexplored perspectives concerning this initial period which, in my opinion, still require additional scrutiny. As I see it, especially when it comes to the Tractatus, Wittgenstein does not “arrive” at the mystical due to the failure of a logical-linguistic inquiry/analysis related to certain realms of knowledge, on the contrary. I will make a case for supposing that the application of logic occurs with the purpose of establishing the scope of the mystical. Therefore, what I propose here is an attempt to develop a “mystical interpretation” of the initial writings of the author. (shrink)

When Anscombe wrote her introduction to the Tractatus, she argued that the book should be approached with an awareness of the logical issues that preoccupied Wittgenstein, especially the work of Russell and Frege.

Perhaps we can say that the book has had a "negative" influence; the mistakes of the Tractatus have helped us to become clearer about the correct way of philosophizing. The difficulty with this view is that many of the criticisms of the Tractatus have been wide of the mark. In denying the influence of the Tractatus, I do not intend to slight its importance. On the contrary, we must distinguish the Tractatus from both logical positivism (...) and Russell's logical atomism, as well as from the subsequent criticisms of these positions, if we are to understand and appreciate it.

Wittgenstein's philosophies, from both the Tractatus and the Philosophical Investigations, are explained and developed. Wittgenstein uses a primitive version of recursion theory to develop his attempt at a purely logical metaphysics in the Tractatus. However, due to his implicit materialist assumptions, he could not make the system completely logical, and built in a mystical division of possible worlds into the true and the false. This incoherence eventually lead him to reject logic as a method for (...) doing metaphysics, and indeed to reject metaphysics entirely. I argue that his move from the Tractatus to the Investigations was valid, but only given his materialist assumptions. If he had been willing to drop this unnecessary baggage, recursion would have played a very different role in his system, since he would then have had no need to separate static objects from processes, which he saw as purely mental. F.H. Bradley developed such a nonmaterialist metaphysics in the nineteenth century, but was crippled by a mentalism that Wittgenstein was free of. The anti-mentalism and anti-materialism that Wittgenstein considered as given were not so obvious to his predecessor, Russell, who revolted against Bradley's idealism in much the same way Wittgenstein ended up revolting against Russell's logical atomism. In my view, none of these positions was the right approach, which would require nonmentalism and nonmaterialism. But for some reason, these things (which seem to go together quite naturally to me) have been widely considered to be incompatible. Bradley was appropriately a non-materialist, but suffered from mentalism. Russell and the early Wittgenstein were appropriately nonmentalists, but suffered from materialism. The later Wittgenstein was, I would argue, still an ardent materialist and anti-mentalist, in spite of the fact that he had long since realized the contradictions to which materialism leads; he just had not recognized that it was his materialist assumptions that had lead him there, since these assumptions were so firmly engrained in his thinking as to be invisible..

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.2 (2003) 281-282 [Access article in PDF] Matthew B. Ostrow. Wittgenstein's Tractatus: A Dialectical Interpretation. New York: Cambridge University Press, 2002. Pp. xi + 175. Paper, $20.00. This contribution to the new readings of the early Wittgenstein presents in detail how one might read the Tractatus as a sustained attack on Frege's and Russell's philosophical and logical conceptions while (...) at the same time presuming Wittgenstein to have always been in some sense a "late Wittgensteinian," that is, already embarked on the therapeutic task of setting down "the way of release" from philosophical confusion and "ensnarement of thought" (1). Taking seriously the passage in the Tractatus (6.54) in which Wittgenstein assesses his "elucidations" as "nonsensical," Ostrow places himself among those readers who infer that straightforward theory-making was not Wittgenstein's aim, but differs from them in his original and challenging account of how the propositions of the Tractatus are nonsense.Wittgenstein, Ostrow contends, employed such (apparent) doctrines as the picture theory, the showing doctrine, the notion of tautology, and so forth dialectically, that is, as self-detonating attempts to expose philosophical nonsense in situ which were not themselves intended to be argued pro or con as philosophical assertions or theories. Wittgenstein's purpose in speaking in the Tractatus in avowedly though not patently nonsensical ways is, the author argues, to encourage us instead to see philosophical nonsensicality as "given in and through" the process of making such philosophical assertions, and in seeing how they "change their character, how they undermine their initial presentation as straightforward truth claims" (12). Thus the "central notions" and propositions in the Tractatus, according to Ostrow, "only have their life in relation to the philosophical temptations that the book aims to eradicate" (43).Such a reading involves the author (and his readers) in a task that is both detailed and delicate. Ostrow's work is detailed because he reads Wittgenstein as engaged in a systematic attempt to expose philosophical theories as nonsense case-by-particular-case, that is, by "working through philosophy from the inside, without making appeal to any kind of fixed criteria of sense and nonsense" (99). It is for this reason that Wittgenstein's articulation of the many structures in the Tractatus is necessary, and Ostrow's work, which he views as largely descriptive, must trace the same path.Ostrow's task is a delicate one because he must explore the themes in Wittgenstein's Tractatus (pictures, significant propositions, logical propositions, etc.) without appearing to contradict his position that the Tractatus offers no general doctrines meant to be taken as they stand. Thus, for instance, when Ostrow argues that for Wittgenstein pictorial form is constituted by a picture's application to reality and not an independent entity, he must remind the reader that he is not attributing to Wittgenstein a doctrine of "constitution of form" offered up as a philosophical alternative. Just as we are not to make pictorial form and its emergence in the Tractatus into a substantive theory in its own right but rather see it as having a role only in Wittgenstein's battle to expose such shibboleths (44), so too for all other parts of the Tractarian structure. Thus Wittgenstein's apparent explanation of the [End Page 281] possibility of depiction in terms of isomorphism is said to aim at showing that as an explanation, "talk of an isomorphism is empty" (39); Wittgenstein's show/say distinction is taken as a foil used to expose the logician's desire to get at essence (42), and so forth. Even the notion of tautology is, according to Ostrow, "as dialectical a move as any other," not one "put forth as a self-standing claim, an attempt to offer an overarching characterization of truth" (105).This book engages in its daunting task very ably and in fluid, confident prose. The author is clearly aware of the various challenges he is likely to meet and suggests ways of doing battle with them. To cite one case, Ostrow examines Wittgenstein's later comments on his...

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)

In this essay, I critically analyze Wittgenstein’s dispensation with “ = ” in a correct concept-script. I argue inter alia (a) that in the Tractatus the alleged pseudo-character of sentences containing “ = ” or = -sentences remains largely unexplained and propose how it could be explained; (b) that at least in some cases of replacing = -sentences with equivalent identity-sign free sentences the use of the notion of a translation seems inappropiate; (c) that in the Tractatus it (...) remains unclear how identity of the object as that which is expressed by identity of the sign should be understood specifically; (d) that there are = -sentences which have no obvious equivalent in Wittgenstein’s novel notation; (e) that Wittgenstein’s adherence to (non-relational) identity, although he dispenses with “ = ”, is probably motivated by his desire to ensure that the expressive power of an identity-sign free concept-script of first-order is on a par with standard first-order logic containing “ = ”. In the concluding section, I critically discuss some claims in Lampert and Säbel (The Review of Symbolic Logic, 14, 1–21, 2021) and defend Wehmeier’s account of pseudo-sentences in the Tractatus (2012) against the objections they raise.

Abstract This paper discusses some recent work on the notion of possibility in Wittgenstein's Tractatus assessed by means of an interpretation of the notion put forward in Cerezo 2005. It argues that the proper way to understand the notion of possibility in the Tractatus must pay equal attention both to the picture theory and the truth-functions theory. From this perspective, through an examination of Peach's proposal (2007) it shows that the role played by the notion of (...) class='Hi'>logical space in the determination of sense needs to be emphasized. In addition, the paper considers some consequences of the Tractarian notion of possibility, namely, the strong contingency of the world that it involves, which is revealed by the thinkability of logical space as empty envisaged by Wittgenstein in T 2.013, and also discusses the recent debate between Reinhardt (2005) and Geach (2006) on this issue.

This paper takes distances from two influential images of Wittgenstein's philosophy: the image of a primarily ethical philosopher defended by the so-called «resolute» interpreters and that of an ascetically "analytical" philosopher transmitted by the standard interpretation. Instead of contrasting images (that of Wittgenstein as an "aesthetic" philosopher and that of the "ethical" Wittgenstein), this paper focuses on the analysis of the fractures and tensions characterizing not only the relationship between Wittgenstein's philosophy and aesthetics, but also the very style (...) of Wittgenstein's thought. Addressing a specific issue from a conceptual and textual standpoint (the unity of Ethics and Aesthetics in the Tractatus) seems to the author to be a fruitful strategy that allows us not only to understand whether and how determinant and central the aesthetic problem is for Wittgenstein, but also to see how aesthetics itself can be radically reshaped through the filter offered by his thought. In the first place, then, it is clarified what the Tractatus claim that ethics and aesthetics «sind eins» might entail. Secondly, it is checked if and how the conceptual consistency of the «being one» of ethics and aesthetics is transformed during the 1930s, to the point that it requires a different configuration: the metamor¬phosis of the logical unity between the two conceptual fields into an analogical affinity. Analyzing this conceptual metamorphosis the paper considers also the idea of an asymmetry of the aesthetic over the ethical as already evident, despite appearances, in the 1929 Lecture on Ethics. This asymmetry is then developed focusing the image of grammatical mechanism with its degrees of freedom of which Wittgensteins writes from 1930. In connection with this image the author outlines finally the idea of an aesthetic mechanism arising from primitive reactions and strictly related with the genesis of language games. (shrink)

I present a reconstruction of the logical system of the Tractatus, which differs from classical logic in two ways. It includes an account of Wittgenstein’s “form-series” device, which suffices to express some effectively generated countably infinite disjunctions. And its attendant notion of structure is relativized to the fixed underlying universe of what is named. -/- There follow three results. First, the class of concepts definable in the system is closed under finitary induction. Second, if the universe of objects (...) is countably infinite, then the property of being a tautology is \Pi^1_1-complete. But third, it is only granted the assumption of countability that the class of tautologies is \Sigma_1-definable in set theory. -/- Wittgenstein famously urges that logical relationships must show themselves in the structure of signs. He also urges that the size of the universe cannot be prejudged. The results of this paper indicate that there is no single way in which logical relationships could be held to make themselves manifest in signs, which does not prejudge the number of objects.

In Carnap’s autobiography, he tells the story how one night in January 1931, “the whole theory of language structure” in all its ramifications “came to [him] like a vision”. The shorthand manuscript he produced immediately thereafter, he says, “was the first version” of Logical Syntax of Language. This document, which has never been examined since Carnap’s death, turns out not to resemble Logical Syntax at all, at least on the surface. Wherein, then, did the momentous insight of 21 (...) January 1931 consist? We seek to answer this question by placing Carnap’s shorthand manuscript in the context of his previous efforts to accommodate scientific theories and metalinguistic claims within Wittgenstein’s Tractatus theory of meaning. The breakthrough of January 1931 consists, from this viewpoint, in the rejection of the Tractatus theory in favor of the meta-mathematical perspective of Hilbert, Gödel, and Tarski. This was not yet the standpoint of the published Logical Syntax, as we show, but led naturally to the “principle of tolerance” and thus to Carnap’s mature philosophy, in which the inconsistencies between this first view and the principle of tolerance, which survived into the published Syntax, were overcome.

In the Preface of the Tractatus Wittgenstein presents his proposal of “drawing limits” separating sense from nonsense as a way to get rid of philosophical problems caused by “misunderstandings of the logic of our language.” Such limits, we will later discover, will be drawn by means of a method which allows one to determine whether a given projection of a strings of signs was made in accordance with the rules of logical syntax, or else violated them, thus generating (...) metaphysical propositions. Notwithstanding its centrality for the Tractatus, the idea of drawing such limits seems to be in tension with Wittgenstein’s actual procedure in most of the book, which from its very first numbered proposition introduces “metaphysical” theses again and again in order to achieve the results programmatically indicated in the Preface—hence the need for the self-undoing message of 6.54, urging the reader to recognize those propositions “as nonsensical, when he has used them—as steps—to climb up beyond them.” That tension creates some of the most challenging questions in the debate about how to read the Tractatus—questions such as: how are we supposed to use Wittgenstein’s propositions as “steps in a ladder”? What exactly does “throwing the ladder away” amount to? And what does it mean to “see the world aright” after “overcoming” those propositions? This paper attempts to answer those questions by means of a close reading of an exemplary set of propositions dealing with solipsism and the limits of language. Although limited in scope, the hope is that such reading might stand as a test case for parallel readings of other parts of the book. (shrink)

Notes on Logic is a painstakingly detailed scholarly study which blends philosophical insight with biographical and historical context to yield a deeper appreciation of the key themes informing Wittgenstein’s philosophical development over his initial period of residence at Cambridge in 1911–13. Notingasurprising gap in the literature on Wittgenstein’s philosophy (p. 3), Potter sets out to treat Wittgenstein’s 1913 “Notes on Logic” (which consists of a succinct summary of the conclusions reached over this initial period) as an independent and primordial philosophical work. While it has been common for serious scholars of Wittgenstein’s Tractatus to “mine” (p. 1) his pre-Tractarian writings in search of “remarks to support their interpretations ” (p. 1) of that text, what sets Potter’s study of the “Notes” apart from previous attempts at exegesis is a methodological determination to approach the “Notes” as “if not quite … a terminus in Wittgenstein’s work then at least as worthy of study in their own right” (p. 1). An important advantage of this approach, according to Potter, is that it facilitates a clearer appreciation of Wittgenstein’s lasting insights “into the central themes of philosophical logic” (p. 262), many of which Wittgenstein himself had already grasped by 1913 and which survive subsequent rejection of some of the less plausible aspects of the Tractatus (such as logical atomism and the picture theory of propositions). By presenting these key insights as consequences of central, but only subsequently adopted, Tractarian doctrines such as the picture theory, however, traditional Wittgenstein scholarship has missed an opportunity, uniquely important in the case of his philosophy (p. 1), to elucidate them against the background of the actual historical landscape of problems, strategies, motivations, and inXuences, within the context in which they were originally formulated. According to Potter, then, looking at the “Notes” as a Wnished work in its own right, as opposed to a mere collection of preparatory notes, will help us to understand better both the more thorough reasoning Wittgenstein worked through in developing these various insights (subsequently either suppressed or highly compressed in the Wnal draft of the Tractatus itselfy), and just what further logical work that subsequently added elements, such as the picture theory, were supposed to contribute. Likewise, such an approach will help us to understand better the relevant inXuences upon Wittgenstein’s philosophical development, such as those, obviously and respectively, of Frege and Russell. Integral to distilling these various insights and inXuences from the “Notes”, according to Potter, is the process of “disentangling” (p. 3) various extant versions of the text from one another, the distinct versions themselves arising from the “rather complicated circumstances” (p. 3) in which the “Notesz” were composed. Following upon a lengthy explication of both the content and philosophical context of the “Notes”, Potter therefore attempts to “reconstruct the circumstances of composition of Wittgenstein’s Wrst surviving philosophical work” (p. 263).

In the Tractatus Logico‐Philosophicus, Wittgenstein adopts a version of logical atomism. This chapter offers an exposition of the Tractarian version of logical atomism. Wittgenstein argues that the constituents of the end products of complete analysis are simple signs, and that there are necessarily existent objects. The chapter explains Wittgenstein's main argument for the possibility of complete analysis. It comments on three recent interpretations of the substance argument and offers an exposition of the substance argument. According to (...) the Tractatus, propositions show the logical form of reality, which is constituted by the logical forms of states of affairs. The substance argument is a reductio ad absurdum. The reductio is the premise that the world had no substance, which is equivalent to the claim that there were no necessarily existent simple objects. The world has substance constituted by necessarily existent simple objects. (shrink)

Contemporary academic interest in the human body is a response to fundamental changes in the relationship between body, economy, technology and society. Scientific advances, particularly new reproductive technologies and therapeutic cloning techniques, have given the human body a problematic status. Ageing, disease and death no longer appear to be immutable facts about the human condition. The emergence of the body as a topic of research in the humanities and social sciences is also a response to the women's and gay (...) liberation movements, and environmentalism, animal rights, anti-globalism, religious fundamentalism and conservative politics. Further, the human body is now central to economic growth in various biotechnology industries, in which disease itself has become a productive factor in the global economy and the body a code or system of information from which profits can be extracted through patents. In modern social theory, the body has been studied in the contexts of advertising and consumerism, in ethical debates about cloning, in research on HIV/AIDS, in postmodern reflections on cybernetics, cyberbodies and cyberpunk, and in the analysis of the global trade in human organs. The body is a central feature of contemporary politics, because its ambiguities, vulnerability and plasticity have been amplified by new genetic technologies. (shrink)

The dissertation analyzes the theory of "logical space" developed by Ludwig Wittgenstein in his Tractatus Logico-Philosophicus, I show how this idea represents a development of arguments first put forward by Hermann von Helmholtz, the physicist and physiologist. Helmholtz--instead of honouring Kant's distinction between on the one hand time and space, and, on the other, empirical qualia --stretched the Kantian spatial manifold to cover the other qualia as well: the qualia are also organized in manifolds; and this new, extended (...) manifold is the "space" of all possible human experience. He explained this a priori mesh as being a consequence of the physiological constitution of our bodies, and the physical constitution of the world in which they are situated. The subject is enclosed in an inner world whose structure is the network of possible sensation; outside of her is a world of unknown complexity; and separating the two is what Heinrich Hertz called the "no-man's-land" of sense-physiology, a border zone regulating all traffic between the two realms, common to both, yet proper to neither. ;Wittgenstein, in his Tractatus, adapted the picture-theories of Helmholtz and Hertz to his analysis of logic. He too was confronted with the problem of defining a field of possible experience, of possible facts: his analysis of Russell's and Frege's logical theories had led him to the conclusion that the fundamental properties of logic could not be accounted for without assuming such an a priori space. Thus he assimilated Russell's types to the dimensions of a manifold, the elements of which were his Sachverhalte, or elementary facts. The truth-functions of our logic are defined on top of this space: it is the basis on which all symbolic systems, including those of the natural sciences, are erected. (shrink)

As its modern edition appears in the Synthese Historical Library, Adam Wodeham’s Tractatus de indivisibilibus does not appear to belong to any one discipline. With regard to its intended audience, the notice of the book appearing on the back cover states that “This book is an important contribution to the history of philosophy.” But it continues, “It will be of interest to all medievalists, particularly to those concerned with medieval science, philosophy, and logic. Theologians and historians of mathematics (...) will also find it useful.”Adam de Wodeham, Tractatus de indivisibilibus. A Critical Edition with Introduction, Translation, and Textual Notes, ed. Rega Wood (Dordrecht: Kluwer Academic Publishers, 1988). In its medieval context as well, Tractatus de indivisibilibus had ambiguous disciplinary status. It begins with the question, “Whether charity or [any] other incorruptible form is composed of indivisible forms.”Wodeham, Tractatus de indivisibilibus, p. 33. Such a reference to charity signals a connection to the Sentences of Peter Lombard, Book I, dist. 17. In introducing his answer to this question, however, Wodeham states, “Because this difficulty is the same for all composite divisible things, whether intensive or extensive, which are of one and the same species or homogeneous, therefore I will briefly inquire indifferently concerning the former and the latter.”Wodeham, Tractatus de indivisibilibus, pp. 34–35. Here and elsewhere, I occasionally modify Rega Wood’s translation in the interests of exactness. The solutions Wodeham then proposes to the questions he asks rely nearly always on logic. (shrink)
