The literature on Heinrich Hertz’s influence on Wittgenstein goes back some way. Not all the main commentators discuss or even notice that influence, although it has been particularly emphasised by James Griffin, by Allan Janik and Stephen Toulmin, and by Leonard Goddard and Brenda Judge.

I discuss the account of logical consequence advanced in Wittgenstein's Tractatus. I argue that the role that elementary propositions are meant to play in this account can be used to explain two remarkable features that Wittgenstein ascribes to them: that they are logically independent from one another and that their components refer to simple objects. I end with a proposal as to how to understand Wittgenstein's claim that all propositions can be analysed as truth functions of elementary propositions.

Al elaborar la noción de un «estado de naturaleza pura» como dotada de un realidad objetiva propia, Francisco Suárez le iba a proporcionar a la filosofía política moderna la herramienta conceptual de la que los filósofos y iusnaturalistas de los siglos XVII y XVIII que se inscriben en su estela se valdrían para desarrollar su pensamiento político y jurídico. En este estudio rastreamos dos de las fuentes medievales de las que Suárez se sirvió en la elaboración de su noción de (...) un «estado de. (shrink)

Tractatus Politico-Philosophicus (Political-Philosophical Treatise) aims to establish the principles of good governance and of a happy society, and to open up new directions for the future development of humankind. W. Julian Korab-Karpowicz demonstrates the necessity of, and provides a guide for, the redirection of humanity. He argues that this paradigm shift must involve changing the character of social life and politics from competitive to cooperative, encouraging moral and intellectual virtues, providing foundations for happy societies, promoting peace among countries and (...) building a strong international community.

In this article I construe Russell's definite description notation as a fragment of an "ideal language"– a language in which, as Russell puts it in the "Logical Atomism" lectures, "the words in a proposition correspond one by one with the components of the corresponding fact." Russell's notation – containing as it does variables, quantifiers and the identity sign – commits him to an ontology that is lavish indeed. It thus conflicts with the spirit of the theory of descriptions, which is (...) developed in the service of ontological frugality. I make use of arguments derived from the Tractatus to show that an ideal language need not contain logical signs. I thus defend the spirit of the theory of descriptions while departing from its letter. (shrink)

It is argued that Wittgenstein’s remarks 6.2-6.22 Tractatus fare well when one focuses on non-quantificational arithmetic, but they are problematic when one moves to quantificational arithmetic.

This paper is divided in four parts. In the first part we introduce the method of internal critique of philosophical theories by examination of their external consistency with scientific theories. In the second part two metaphysical and one epistemological postulate of Wittgenstein's Tractatus are made explicit and formally expressed. In the third part we examine whether Tractarian metaphysical and epistemological postulates (the independence of simple states of affairs, the unique mode of their composition, possibility of complete empirical knowledge) are (...) externally consistent with the theory of quantum mechanics. The result of the inquiry is negative: Tractarian postulates ought to be be revised. Relying on the result we approach the question of the empirical character of logic in the fourth part. The description of theoretical transformations of the notion of disjunction, in its ontological, epistemological, and logical sense, is a common element of in all parts of the text. The conjecture on the existence of different types of disjunctive connectives in the language of quantum mechanics concludes the paper. (shrink)

On many interpretations of Spinoza’s political philosophy, democracy emerges as his ideal type of government. But a type of government can be ideal and yet it can be unwise to implement it if certain background conditions obtain. For example, a dominion’s people can be too ‘wretched by the conditions of slavery’ to rule themselves. This begs the following question. Do Spinoza’s arguments for democracy entail that all political bodies should be democracies at all times (the received view), or do they (...) merely entail that we should only have a democracy when the right sort of background conditions are in place (the challenging view)? This paper argues that a new interpretation of one of the four versions of the rationality argument for democracy as it features in the Tractatus entails that the received view is correct. The paper also explains away part of the appeal of the challenging view by arguing that none of the other versions of the rationality argument supports the received view. It closes by arguing that a slightly modernised version of the rationality argument can be important for contemporary political philosophy. (shrink)

‘Tractatus, since I first read it, has been a constant source of philosophical inspiration to me’ so says Ganguly in the preface of his book Wittgenstein’s Tractatus: A Preliminary. This extraordinary commentary on Tractatus is unique in the sense that it has discussed all the commentaries available at that time while examining and critiquing, wherever necessary, the commentaries as well as the original with utmost passion and sincerity. His approach to the author was feasibly sympathetic and sensitive, (...) though he never fails in his duty of being a rigorous critique while examining an apparent inconsistency or weak arguments. As it is nearly impossible to deal with all the contentious topics of the Tractatus that Ganguly dealt with in a single paper, I would like to concentrate only on the fundamental claim of Ganguly that the Tractatus 6.54 cannot really get Wittgenstein out of the paradoxical situation. Hence the paper will be divided into three main sections. In the first section, the paper will deal with the palpable paradox that results from the reading of Tractatus 6.54 and the controversies involved in various interpretations of the paradox. In the second section, there will be an attempt to focus on the problem of description in the distinction between saying and showing, between thinking and imagining, between thought and reality in order to understand the annotation of T6.54 by Ganguly. In the third section, there will be an attempt on my part to interpret the paragraph Tractatus 6.54 in the light of the distinction between Sinnloss and Unsinn from a non-resolute perspective and evaluate Ganguly’s account of the paragraph in question from that perspective.

Reading the Tractatus. And appreciating it The reception history of Wittgenstein’s Tractatus Logico-Philosophicus displays an impressive and persistent diversity. This paper explores possible sources of that diversity and locates them in different takes on the text and its context of origin, and in different perspectives of the readers. This hermeneutics is illustrated by a comparison of two views on the importance of ethics for an understanding of the Tractatus: that of Cora Diamond and the one developed by (...) the authors in previous work.

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.

Je pose une question concernant la place du Tractatus de Wittgenstein dans la tradition éthique. Le Tractatus et la tradition éthique Les remarques que je ferai sont à considérer dans le contexte d'une interprétation du Tractatus qui a été qualifiée de lecture résolue de cette œuvre, ainsi que de la philosophie de Wittgenstein en général Comme l'a écrit Cora Diamond, le Tractatus travaille sur la libération des besoins et des désirs philosophiques, une libération de la philosophie (...) effectuée avec des outils philosophiques : la situation du Tractatus est similaire à celle évoquée dans les Recherches et dans l'œuvre ultérieure, qui se consacre également au projet de se libérer de la philosophie pour le bien de la philosophie.

En el presente artículo, me centraré únicamente en la ontología del Tractatus porque, a pesar de ser uno de los temas que abandona después de 1930, tiene dos aspectos que quisiera resaltar de manera especial: su carácter relacional, y su afirmación de la contingencia del mundo. Considero que ambos son de interés en sí mismos por su carácter inédito, pero creo, además, que es posible establecer sugerentes relaciones entre ellos y algunas posiciones contemporáneas, tanto de las ciencias naturales como (...) de las ciencias sociales. En el primer caso, haré referencia al libro recientemente publicado de Friedrich Hülster, Introduction to Wittgenstein´s Tractatus Logico-Philosophicus. Para el segundo, tomaré como punto de partida Radical Uncertainty, publicado el año pasado por John Kay y Marvyn King. (shrink)

"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)

In the Tractatus Logico-Philosophicus Wittgenstein writes:2.022 It is obvious that an imagined world, however different it may be from the real one, must have something – a form – in common with it.2.023 Objects are just what constitute this unalterable form.As F.P. Ramsey pointed out, in his insightful review of the Tractatus, it is evident:[i]that Wittgenstein is here envisaging a multitude of possible worlds other than the real one;[ii]that Wittgenstein is claiming that, notwithstanding their diversity, all such worlds (...) have a common form; and[iii]that Wittgenstein believes this form to be somehow 'constituted' by the simple objects that exist in these worlds.

Written in short, carefully numbered paragraphs of extreme compression and brilliance, it immediately convinced many of its readers and captured the imagination of all. Its chief influence, at first, was on the Logical Positivists of the 1920s and 1930s, but many other philosophers were stimulated by its philosophy of language, finding attractive, even if ultimately unsatisfactory, its view that propositions (...) were pictures of reality. Perhaps most of all, its own author, after his return to philosophy in the late 1920s, was fascinated by its vision of an inexpressible, crystalline world of logical relationships. C.K. Ogden's translation of the Tractatus Logico-Philosophicus has a unique provenance. As revealed in Letters of C.K. Ogden and in correspondence in The Times Literary Supplement , Wittgenstein, Ramsey and Moore all worked with Ogden on the translation, which had Wittgenstein's complete approval. The very name Tractatus Logico-Philosophicus was of Ogden's devising; and there is very strong feeling among philosophers that, among the differing translations of this work, Ogden's is the definitive text - and Wittgenstein's version of the English equivalent of his Logisch-Philosophische Abhandlung.

The philosophy of arithmetic of Wittgenstein's Tractatus is outlined and the central role played in it by the general notion of operation is pointed out. Following which, the language, the axioms and the rules of a formal theory of operations, extracted from the Tractatus, are presented and a theorem of interpretability of the equational fragment of Peano's Arithmetic into such a formal theory is proven.

In the Tractatus Wittgenstein criticizes Frege and Russell's view that laws of inference (Schlussgesetze) "justify" logical inferences. What lies behind this criticism, I argue, is an attack on Frege and Russell's conceptions of logical entailment. In passing, I examine Russell's dispute with Bradley on the question whether all relations are "internal".

Le premier Wittgenstein expose dans le Tractatus une philosophie des sciences marquée par le conventionnalisme complété d’un certain vérificationnisme assuré par la logique de l’ Abbildung. Pour autant il ne développe aucune idéologiste scientiste. A partir de 1929, sa philosophie prend un tournant grammatical : la « grammaire » de la science comporte non seulement les lois logiques, mais aussi la partie théorique des sciences de la nature. L’assimilation des grandes théories (Copernic, Darwin, Freud) à des « vues synoptiques (...) » rassemblant une quantité de phénomènes, comme les paradigmes de Kuhn, n’empêche pas Wittgenstein de donner à sa philosophie le tour d’un incontestable réalisme (au sens de Cora Diamond). La dernière partie de ce texte essaie d’apprécier, à partir de Wittgenstein, les différences et les relations entre science et philosophie dans le naturalisme contemporain. (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.

The philosophies of late Brentano and early Wittgenstein can be brought closer in two ways. One way discovers a surprising amount of part-whole theory in the Tractatus if we see states of affairs (not wholly wilfully) as thinglike rather than factlike. This throws up a modal analogue to Chisholm's entia successiva in the form of situations. The other way sees all propositions as truth-functions of existential propositions, supporting Brentano's view that existentials are primary, and incidentally yielding a reistic semantics (...) for the Tractatus. I draw a quick moral, that we should beware of excessive simplicity in metaphysics, and apply it to Chisholm's views on part and whole. (shrink)

In the Tractatus Wittgenstein claims that a sentence expresses the same proposition in every possible world and, hence, which proposition is expressed cannot depend on how each world is. In this paper, I shall explore the interpretation of this thesis under the perspective of Stalnaker’s theory of assertions as the reduction of the context set, i.e., the set of possible worlds compatible with the information gathered at a conversation. In Stalnaker’s version, this principle follows from the explication of assertions (...) as having the illocutionary point of excluding some possible worlds from the context set. If there is no unique instruction to exclude some worlds, then it is not clear which reduction is meant by the speaker. This might lead to a better understanding of Wittgenstein’s own version. (shrink)

The text of The Tractatus supports incompatible interpretations of a number of key philosophic positions. For example, the book is neither obviously nominalistic nor obviously realistic. Another difficulty is presented by the apparent. incompatibility of Wittgenstein's theses that propositions are logical pictures of facts, and that propositions are truth-functions of elementary propositions. There are several places in The Tractatus where these two doctrines meet head on, but the central one is the set of passages 5.54-5.5422. This paper is (...) an exegesis of these passages and a sketch of Wittgenstein's theory of judgement.In Tractatus 5.54 - 5.5422, Wittgenstein argues that statements of belief, judgement, thoughts and the like are not incompatible with the principle of finite extensionality. The passages contain a brief but obscure reductio on the possibility of non-extensional contexts, and several no less obscure corollaries. In this paper I shall explicate the content of the reductio, criticise a common but mistaken view of these passages, and draw out the consequences of some major doctrines in the Tractatus for Wittgenstein's Theory of Judgement.

I discuss some reservations about the exegetical power of the claim that the Tractatus is “anti-metaphysical.” The “resolute” reading has the virtue of fidelity to important and neglected features of the work, both its anti-metaphysical moves and its account of the nature of the activity of philosophy and its status. However, its proponents underestimate the barriers to maintaining a consistent fidelity to these features of the text. The image of a ladder suggests a mere instrumental means to arrive at (...) a place that can itself be characterized independently of our means of arrival; where we arrive via the process of the TLP is the conclusion of an argument, and so cannot be characterized independently of the argument that got us there. In his commitments about the process of logical analysis “within language,” he strives as much as in his statements about the world to return us to our ordinary ways of talking and making sense of what we say to one another. Given the internal relationship Wittgenstein is at pains to emphasize between language, thought, and reality, he could hardly have philosophical commitments about one of these terms (have a residual metaphysics of language) and isolate this from how he thinks about the others. In a discussion of “Senator, you’re no Jack Kennedy” and “Chairman Mao is rare,” I argue that, pace Conant and Diamond’s claims to the contrary, logical categories are being invoked to explain why one cannot mean what one thinks one means in this phrase, and that Wittgenstein is both more anti-metaphysical in his treatment of these logical categories (in contrast with Frege) than the resolute readers consider him to be, and less successful in his treatment of how logical categories rule our judgments of sense and nonsense than they imply he is. Finally, I question the sharp boundary between logic and psychology and the “claustrophobic” feel that is created by a narrow construal of what one can make sense of in another’s words and person that underwrites their account of nonsense via a conflict between the meaning words can contain and our confused desires. Throughout, I discuss relevant passages of the Investigations that resolute readers treat as a re-expression of the themes of the Tractatus, to contrast the “anti-metaphysical” treatment these themes express in the Tractatus with the less dogmatic treatment they receive in the Investigations.

Der Begriff 'Sinn' wird im Tractatus in mehrfachem Sinn gebraucht und dem Wertbegriff angenähert. Die Wertprädikate wie 'schön' und 'gut' gehören aber im Tractatus zum Unsinnigen. Während das Sinnvolle in der Beschreibung der Wirklichkeit besteht und das Sinnlose als Grundlage der Deutung der Logik funktioniert, soll das Unsinnige schlechthin unaussag- und undenkbar sein. Dennoch ist es möglich, zwischen zwei Arten des Unsinnigen im Tractatus zu unterscheiden: (1) was gezeigt werden kann, (2) was ohne irgendwelche kognitive Funktion ist. (...) Das mystische Zeigen wird in der späteren Philosophie Wittgensteins entmystifiziert. In ihr kann man auch einer gewissen Differenzierung zwischen der ethischen Charakterisierung und der ästhetischen Charakterisierung der Wirklichkeit nachspüren. (shrink)

This paper is concerned with the status of a symbol in Wittgenstein’s Tractatus. It is claimed in the first section that a Tractarian symbol, whilst essentially a syntactic entity to be distinguished from the mark or sound that is its sign, bears its semantic significance only inessentially. In the second and third sections I pursue this point of exegesis through the Tractarian discussions of nonsense and the context principle respectively. The final section of the paper places the forgoing work (...) in a secondary context, addressing in particular a debate regarding the realism of the Tractatus. (shrink)

Wittgenstein’s Tractatus is one of the most important philosophical works of the Twentieth Century, yet it is brief and offers little orientation for the reader. This causes two problems: The first-time reader is left wondering what it could be about, and often leaves off reading in frustration after a few pages. The scholar is left with little guidance for interpretation. This paper recounts selected material from my book Tractatus in Context. While the book includes familiar material from Wittgenstein’s (...) notebooks and letters, it also includes lesser-known material such as untranslated correspondence and notebook entries, later lectures and dictations, notes from Ramsey, and previously unknown reviews. Some of the topics to be examined are: simple objects, atomic facts and elementary propositions, limits and boundaries, superstition, the shape of the visual field, and the role of the will. Given the occasion, I’ll also focus on some ways in which conversations with the Vienna Circle help illuminate obscure passages in the Tractatus. (shrink)

The notion of the riddle plays a pivotal role in Wittgenstein’s Tractatus . By examining the comparisons he draws between philosophical problems and riddles, this paper offers a reassessment of the aims and methods of the book. Solving an ordinary riddle does not consist in learning a new fact; what it requires is that we transform the way we use words. Similarly, Wittgenstein proposes to transform the way philosophers understand the nature of their problems. But since he holds that (...) these problems are ultimately unsolvable, rather than attempting to solve the riddles of philosophy, he aims to dissolve them. (shrink)

The article argues for a contextualised reading of Wittgenstein’s Tractatus. It analyses in detail the role that use and application play in the text and how that supports a conception of transcendentality of logic that allows for contextualisation. The article identifies a tension in the text, between the requirement that sense be determinate and the contextual nature of application, and suggests that it is this tension that is a major driver of Wittgenstein’s later ideas.

The paper focuses attention on Jerome’s interpretation of Ps. 15,8 in Tractatus in psalmum 15. After an introduction dealing with the right way to translate the verse according to Hebraica veritas, which shows his philological skills, he reveals his exegesis. The opening and concluding parts of this exegesis follow closely the Origen’s Homily on Psalm 15, but the long central section about the righteous highlights the particularity of Jerome’s exegesis; he uses other interpretations of Origen’s, but subordinates them to (...) his own concerns to achieve original results. The study offers further proofs in favour of a proposal for dating this text. (shrink)
