In broadest terms, this thesis is concerned to answer the question of whether the view that arithmetic is analytic can be maintained consistently. Lest there be much suspense, I will conclude that it can. Those who disagree claim that accounts which defend the analyticity of arithmetic are either unable to give a satisfactory account of the foundations of mathematics due to the incompleteness theorems, or, if steps are taken to mitigate incompleteness, then the view loses the ability to account for the applicability of mathematics in the sciences. I will show that this criticism is not successful against every view whereby arithmetic is analytic by showing that the brand of "conventionalism" about mathematics that Rudolf Carnap advocated in the 1930s, especially in Logical Syntax of Language, does not suffer from these difficulties. There, Carnap develops an account of logic and mathematics that ensures the analyticity of both. It is based on his famous "Principle of Tolerance", and so the major focus of this thesis will to defend this principle from certain criticisms that have arisen in the 80 years since the book was published. I claim that these criticisms all share certain misunderstandings of the principle, and, because my diagnosis of the critiques is that they misunderstand Carnap, the defense I will give is of a primarily historical and exegetical nature. Again speaking broadly, the defense will be split into two parts: one primarily historical and the other argumentative. The historical section concerns the development of Carnap's views on logic and mathematics, from their beginnings in Frege's lectures up through the publication of Logical Syntax. Though this material is well-trod ground, it is necessary background for the second part. In part two we shift gears, and leave aside the historical development of Carnap's views to examine a certain family of critiques of it. We focus on the version due to Kurt Gödel, but also explore four others found in the literature. In the final chapter, I develop a reading of Carnap's Principle - the `wide' reading. It is one whereby there are no antecedent constraints on the construction of linguistic frameworks. I argue that this reading of the principle resolves the purported problems. Though this thesis is not a vindication of Carnap's view of logic and mathematics tout court, it does show that the view has more plausibility than is commonly thought.

La métaphysique comme branche de la littérature fantastique : une lecture wittgensteinienne de Borges. L'une des formules de Borges tient que la "métaphysique" n'est qu'une branche de la littérature fantastique. Caractérisant la logique borgésienne d'une "ludique" herméneutique - celle de lire les textes philosophiques à partir des narrativités qu'ils autorisent- cette remarque semble pourtant soulever une question proprement philosophique : celle du statut de notre concept ordinaire d'objet. D'après la proposition wittgensteinienne, notre concept d'objet physique n'est qu'un concept "logique". La question demeure ainsi de savoir si nos jeux de langage ordinaire épuisent sa grammaire, et dans quelle mesure les fictions et les essais de Borges, qui jouent avec celle-ci, devraient être considérés comme un élargissement, ou bien comme une distorsion de la grammaire ordinaire de l'objet. Il s'agira ainsi d'interroger, d'un côté, si les textes borgésiens tolèrent une lecture analytique ; d'un autre, de démontrer comment la fiction, en recadrant à chaque fois le partage entre dire et montrer, permet d'en détourner, ou bien d'en dépasser la "logique". / Metaphysics as a branch of fantastic literature: a Wittgensteinian reading of Borges. One of Borges' slogans holds that "metaphysics" is only a branch of fantastic literature. Characterizing the Borgesian logic behind a playful hermeneutics -i.e., the possibility to read philosophy througout the narrativities it authorizes- this remark seems to raise a strictly philosophical question, namely that of the status of our ordinary concept of object. According to Wittgenstein, our concept of physical object is just a "logical" concept. The question thus remains whether our ordinary language games exhaust its grammar, and to what extent Borges' fictions and essays, as an attemp to play with it, should be regarded as an extension, or rather as a distortion of the ordinary grammar of the object. It will thus be necessary to inquiry, on the one hand, whether the Borgean texts tolerate an analytic reading; on the other, to show how each fiction, by reframing all over again the split between saying and showing, makes it possible to divert or rather to go beyond its "logic".

No form of philosophy is without literary style. This is not always appreciated and opponents of style within philosophy often seem to be unaware of the role of style. Arguments that style is bad, good, or that diversity of styles is good needs to be investigated so that the underlying presuppositions and the meaning of different literary styles becomes clear. This thesis examines three arguments for and against style within philosophy and the relevance of literary style for the philosophical method. I investigate what arguments and fundamental assumptions about language that underlies the judgments that literary style in philosophy is either 1.) bad, 2.) good or, 3.) both bad and good (a diversity position). An analysis of three different positions to the question of the relevance of style will be performed. The analysis focuses on the basic understandings of what language is and does and reveals the underlying presuppositions of the attitudes towards style in philosophy. Only then can the different positions and attitudes towards style be defended and examined in an interesting and relevant way. The debate about philosophical style often misses a significant point because many are unaware of the philosophical presuppositions behind the arguments, and the argumentation risks to be flawed in relation to this. Firstly, a presentation of three different attitudes towards the relevance of style to the philosophical method is outlined. The approaches are represented by a reading of philosophers who either describe the relevance of literary style as 1.) bad, or not important for the method, 2.) important/necessary for the method, or 3.) that diversity is good for philosophy. Secondly, I examine how these three approaches are affected by the underlying philosophy of language with a focus on theories of metaphor. Depending on how one believes that language is related to reality and ourselves, one will assess style as a more, or less, relevant and contributing aspect of the philosophical work and method. The analysis shows that metaphors and other literary stylistic tools might sometimes be necessary and mediate something that cannot be expressed in another way: language can never capture the full potential of reality.

O presente trabalho visa entender como o rádio se distingue dos demais sons do mundo. A hipótese aqui formulada é a de que o rádio, em sua definição, é uma linguagem, e não um aparelho. Dessa maneira, há a busca por uma caracterização da linguagem radiofônica seguindo as ideias implicadas em uma Estética da Linguagem (Derrida e antiessencialistas como Ziff, Weitz e Kennick). Com isso, há um estudo detalhado do rádio em seu jogo de linguagem (Wittgenstein) e em seus diferendos (Lyotard), considerados aqui enquanto parergon e ergon, ou seja, enquanto recorte e modelo operacional da linguagem em sua intersecção com o mundo. Para a investigação do jogo de linguagem, foram utilizados conteúdos relacionados à Filosofia Analítica, à Lógica Algébrica e à Teoria dos Jogos para desenvolver um método analítico denonimado Jogo Lógico, voltado para o estudo de jogos de linguagem comunicacionais. Já para a investigação dos diferendos, foram utilizadas as ideias pragmáticas acerca da performatividade e da lógica ilocucionária (Austin e Searle) para analisar os gêneros radiofônicos (a saber: musical, radiojornalismo, esportivo, variedades [talk radio], humorístico, ficção e publicidade). Essas duas investigações formam aquilo que é chamado aqui de Gramática do Rádio - considerando o conceito wittgensteiniano de gramática -, o ponto nodal que nos permite caracterizar o rádio enquanto linguagem. / The present work aims to understand how the radio distinguishes itself from other sounds of the world. The hypothesis formulated here is that the radio, in its definition, is a language, not a machine. Thus, there is the search for a characterization of radio\'s language following the ideas involved in an Aesthetics of Language (Derrida and anti-essentialists like Ziff, Weitz and Kennick). Here, there is a detailed study of the radio in its language-game (Wittgenstein) and their differends (Lyotard), considered in this work as parergon and ergon, i.e. as the cut and the operational model of language in its intersection with the world. For the investigation of the language-game, we used content related to Analytic Philosophy, to Algebraic Logic, and to Game Theory to develop an analytical method called Logic Game, dedicated to the communicative language-games\' study. As for the investigation of differends, we used the pragmatic concepts about the performative and illocutionary logic (Searle and Austin) to analyze the radio genres (ie: music, radio journalism, sports, talk radio, humor, fiction and advertising). These two studies form what is called here the Radio Grammar - considering the Wittgensteinian concept of grammar - the key point that allows us to characterize the radio as a language.

A pesquisa que ora se apresenta consiste em uma investigação sobre o recente trabalho de reavaliação das obras de membros do chamado Círculo de Viena, que foi o primeiro e principal grupo representativo da perspectiva filosófica conhecida como positivismo lógico. Nossa pesquisa compreende três partes: a primeira parte voltada para a reconstrução histórico-conceitual do período entre o alvorecer das idéias neopositivistas e os primeiros momentos posteriores à recepção norte-americana da imigração intelectual vienense; na segunda parte do trabalho, por sua vez, lançaremos luz propriamente à natureza de tal perspectiva contemporânea, a partir de uma descrição sobre o método e o escopo temático de tal projeto revisionista; à terceira parte, por fim, além de tecer uma avaliação geral sobre o que foi feito nas duas partes que a antecedem, coube conjecturar as possibilidades de se encontrar em tal trabalho uma agenda filosófica e política própria. / The present work consists on an inquiry concerning the recent re-evaluation in the works of members of the so-called Vienna Circle, which became the first and main representative of the philosophical movement known as Logical Positivism. Our research comprises three parts: the first one is devoted to a historical-conceptual reconstruction of the period between the uprising of the first Neopositivist ideas and the years immediately following the North-American reception of the intellectual immigration from Vienna; the second part of the work concerns the nature of such contemporary reappraisal researches on the positivists legacy, through a description of the method and scope of such re-evaluation project; finally, the third part comprises a general review of the previous parts, and was worked out in order to conceive conjectures about the possibility of finding out in this re-evaluation project a philosophical and political agenda of its own.

Cette thèse de doctorat est consacrée à la pensée du philosophe américain Nelson Goodman (1906-1998). Nous y défendons, à l’encontre de la plus grande partie de la critique, une lecture métaphysicienne de son œuvre. Il est démontré que Goodman, dans tous ses travaux, développe une métaphysique technique et méconnue, dont les piliers sont le nominalisme, le pluralisme, le perdurantisme, l’actualisme, et l’universalisme méréologique. Cette lecture permet de réévaluer l’ensemble de la pensée goodmanienne. Elle établit aussi ses liens insoupçonnés avec la métaphysique analytique contemporaine / This PhD dissertation is dedicated to the philosophy of Nelson Goodman (1906-1998). We defend, against most critics, a metaphysical interpretation of Goodman’s works. It will be shown that the latter developed a technical and often overlooked metaphysics, whose pillars are nominalism, pluralism, perdurantism, actualism, and mereological universalism. This reading allows for a critical reevaluation of Goodman’s views. It also brings to light his unexpected links with contemporary analytic metaphysics

This thesis outlines the three phases of cognitivism, which emerged in the first half of the 20th century as a reaction to the anti-mentalist tradition of philosophical thinking (represented by Charles S. Peirce and Charles Morris), and which was made possible in particular by the so- called linguistic turn in science (especially within analytic philosophy), which replaced mental units, regarded as non-scientific, with linguistic units, conceived as reflecting mental states and, moreover, allowing for adequate investigation. The thesis is largely guided by Thomas C. Daddesio's On Minds and Symbols, which is considered to be one of the first explicit attempts to formulate a cognitive-semiotic perspective, and wherein the author traces the previous development of the cognitive paradigm. Thus, first the factors that made the emergence of cognitivism possible are described, followed by an account of its development, which can be divided into two phases, as per Daddesio's model. This paper, however, goes beyond Daddesio's book and establishes a third phase, where cognitivism emerges as a separate field of inquiry within semiotics, i.e., cognitive semiotics. Within this development, the work traces in particular the transformation of the conception of the relationship between language and mind, which is...

Cette thèse part d’une constatation troublante : une œuvre littéraire et sa traduction sont deux textes différents. Comment deux textes différents peuvent-ils s’annuler, être indiscernables en tant qu’œuvre ? Y a-t-il une œuvre, deux œuvres distinctes, ou plutôt, comme nous le proposerons provisoirement, une œuvre relationnelle, la traduction littéraire. Cette relation est en fait une dépendance que nous théorisons, avant de proposer une théorie procéduraliste institutionnelle de l’œuvre et de montrer que les traductions littéraires ne sont pas des œuvres, mais des compositions substitutives, « œuvre » étant un statut qui chapeaute toutes les compositions qui la font fonctionner. Nous montrons en outre qu’elles appartiennent aux pratiques artistiques, qui regroupent un certain nombre d’activités et d’artefacts essentiels au fonctionnement des œuvres d’art. « Œuvre » étant un statut, cela a comme conséquence qu’« auteur » en est un aussi. Nous tentons ensuite de déterminer si le traduire s’étend à toutes les activités de compréhension, ou s’il y a une spécificité du traduire interlinguistique littéraire. Par la suite, nous étudions les deux principales attitudes qui s’offrent au traducteur au moment de traduire : les approches sourciste et cibliste. Après quoi nous examinons qui est le lecteur d’une traduction littéraire et dans quelle mesure il se distingue du lecteur de la composition en langue première. Après un examen de la compréhension d’un point de vue empirique, nous en venons à la conclusion que le critère de réussite pour la lecture est la compréhension. Cela nous permet de proposer une étude du critère de fidélité en fonction de la compréhension, tout en précisant qu’une œuvre, étant un statut, n’est jamais traduite. Pour finir, après avoir appliqué notre théorie aux traductions de Shakespeare réalisée par Voltaire, nous montrons que la pensée de la traduction est travaillée par une méprise ontologique qui confond fidélité sémantique et fidélité ontologique. / This dissertation starts from a troubling observation: a literary work and its translation are two different texts. How can two different texts cancel each other out, be indiscernible? Is there one work, two distinct works, or rather, as we will provisionally propose, a relational work, the literary translation. This relation is in fact a dependence that we theorize, before proposing an institutional proceduralist theory of the work and showing that literary translations are not works, but substitute compositions, "work" being a status that encompasses all the compositions that make it work. We further show that literary translations belong to artistic practices, which bring together a number of activities and artefacts essential to the functioning of works of art. "Work" being a status, the consequence is that "author" is also one. We then attempt to determine whether translating extends to all the activities related to understanding, or whether there is a specificity to literary interlinguistic translating. Next, we study the two main attitudes available to the translator when translating: the sourceand target-oriented approaches. We then consider who the reader of a literary translation is and how he differs from the reader of the first-language composition. After studying understanding from an empirical point of view, we come to the conclusion that a successful reading is one through which the read work is understood. This allows us to unfold a study of faithfulness according to understanding, before concluding that a work, being a status, is never translated. Finally, having applied our theory to the Voltaire’s translations of Shakespeare, we show that the theory of translation is dominated by an ontological misunderstanding which confuses semantic and ontological faithfulness.
