What requirements must deflationary formal theories of truth satisfy? This chapter argues against the widely accepted view that compositional and Tarskian theories of truth are substantial or otherwise unacceptable to deflationists. First, two purposes that a formal truth theory can serve are distinguished: one descriptive, the other logical (i.e., to characterise the correctness of inferences involving ‘true’). The chapter argues that the most compelling arguments for the incompatibility of compositional and Tarskian theories concern descriptive theories only. -/- Second, two requirements (...) that any deflationist truth theory intended to serve a logical purpose must satisfy are put forward. These requirements, it is argued, suggest that (i) many well-known compositional and Tarskian theories are acceptable from a deflationist standpoint (including CT); (ii) certain other popular theories of truth (including KF and FS) are not similarly acceptable; (iii) there are no conclusive reasons to impose a conservativeness requirement on deflationary theories of truth.

Stephen Yablo [23,24] introduces a new informal paradox, constituted by an infinite list of semi-formalized sentences. It has been shown that, formalized in a first-order language, Yablo’s piece of reasoning is invalid, for it is impossible to derive falsum from the sequence, due mainly to the Compactness Theorem. This result casts doubts on the paradoxical character of the list of sentences. After identifying two usual senses in which an expression or set of expressions is said to be paradoxical, since second-order (...) languages are not compact, I study the paradoxicality of Yablo’s list within these languages. While non-paradoxical in the first sense, the second-order version of the list is a paradox in our second sense. I conclude that this suffices for regarding Yablo’s original list as paradoxical and his informal argument as valid. (shrink)

Deflationists claim that the truth predicate was introduced into our language merely to full a certain logico-linguistic function. Oddly enough, the question what this function exactly consists in has received little attention. We argue that the best way of understanding the function of the truth predicate is as enabling us to mimic higher-order quantification in a first-order framework. Indeed, one can show that the full simple theory of types is reducible to disquotational principles of truth. Our analysis has important consequences (...) for our understanding of truth. In this paper, we can only touch on one of them: we will argue that the insubstantiality of truth does not imply a conservativity requirement on our best theories of truth. (shrink)

One of the main logical functions of the truth predicate is to enable us to express so-called ‘infinite conjunctions’. Several authors claim that the truth predicate can serve this function only if it is fully disquotational, which leads to triviality in classical logic. As a consequence, many have concluded that classical logic should be rejected. The purpose of this paper is threefold. First, we consider two accounts available in the literature of what it means to express infinite conjunctions with a (...) truth predicate and argue that they fail to support the necessity of transparency for that purpose. Second, we show that, with the aid of some regimentation, many expressive functions of the truth predicate can actually be performed using truth principles that are consistent in classical logic. Finally, we suggest a reconceptualisation of deflationism, according to which the principles that govern the use of the truth predicate in natural language are largely irrelevant for the question of what formal theory of truth we should adopt. Many philosophers think that the paradoxes pose a special problem for deflationists; we will argue, on the contrary, that deflationists are in a much better position to deal with the paradoxes than their opponents.

Weakening classical logic is one of the most popular ways of dealing with semantic paradoxes. Their advocates often claim that such weakening does not affect non-semantic reasoning. Recently, however, Halbach and Horsten have shown that this is actually not the case for Kripke’s fixed-point theory based on the Strong Kleene evaluation scheme. Feferman’s axiomatization $\textsf{KF}$ in classical logic is much stronger than its paracomplete counterpart $\textsf{PKF}$, not only in terms of semantic but also in arithmetical content. This paper compares the (...) proof-theoretic strength of an axiomatization of Kripke’s construction based on the paraconsistent evaluation scheme of $\textsf{LP}$, formulated in classical logic with that of an axiomatization directly formulated in $\textsf{LP}$, extended with a consistency operator. The ultimate goal is to find out whether paraconsistent solutions to the paradoxes that employ consistency operators fare better in this respect than paracomplete ones. (shrink)

Self-reference has played a prominent role in the development of metamathematics in the past century, starting with Gödel’s first incompleteness theorem. Given the nature of this and other results in the area, the informal understanding of self-reference in arithmetic has sufficed so far. Recently, however, it has been argued that for other related issues in metamathematics and philosophical logic a precise notion of self-reference and, more generally, reference is actually required. These notions have been so far elusive and are surrounded (...) by an aura of scepticism that has kept most philosophers away. In this paper I suggest we shouldn’t give up all hope. First, I introduce the reader to these issues. Second, I discuss the conditions a good notion of reference in arithmetic must satisfy. Accordingly, I then introduce adequate notions of reference for the language of first-order arithmetic, which I show to be fruitful for addressing the aforementioned issues in metamathematics. (shrink)

I put forward precise and appealing notions of reference, self-reference, and well-foundedness for sentences of the language of first-order Peano arithmetic extended with a truth predicate. These notions are intended to play a central role in the study of the reference patterns that underlie expressions leading to semantic paradox and, thus, in the construction of philosophically well-motivated semantic theories of truth.

I apply the notions of alethic reference introduced in previous work in the construction of several classical semantic truth theories. Furthermore, I provide proof-theoretic versions of those notions and use them to formulate axiomatic disquotational truth systems over classical logic. Some of these systems are shown to be sound, proof-theoretically strong, and compare well to the most renowned systems in the literature.

Truth predicates are widely believed to be capable of serving a certain logical or quasi-logical function. There is little consensus, however, on the exact nature of this function. We offer a series of formal results in support of the thesis that disquotational truth is a device to simulate higher-order resources in a first-order setting. More specifically, we show that any theory formulated in a higher-order language can be naturally and conservatively interpreted in a first-order theory with a disquotational truth or (...) truth-of predicate. In the first part of the paper we focus on the relation between truth and full impredicative sentential quantification. The second part is devoted to the relation between truth-of and full impredicative predicate quantification. (shrink)

It is widely accepted that a theory of truth for arithmetic should be consistent, but -consistency is a highly desirable feature for such theories. The point has already been made for first-order languages, though the evidence is not entirely conclusive. We show that in the second-order case the consequence of adopting -inconsistent theories of truth are considered: the revision theory of nearly stable truth T # and the classical theory of symmetric truth FS. Briefly, we present some conceptual problems with (...) ω-inconsistent theories, and demonstrate some technical results that support our criticisms of such theories. (shrink)

The Yablo Paradox’ main interest lies on its prima facie non-circular character, which many have doubted, specially when formulated in an extension of the language of firstorder arithmetic. Particularly, Priest (1997) and Cook (2006, forthcoming) provided contentious arguments in favor of circularity. My aims in this note are (i) to show that the notion of circularity involved in the debate so far is defective, (ii) to provide a new sound and useful partial notion of circularity and (iii) to show there (...) is a non-circular formulation of the list in an extension of the language of first-order arithmetic according to the new notion. El interés principal de la Paradoja de Yablo yace en su carácter prima facie no circular, el cual ha sido puesto en duda especialmente con respecto a la formulación de la paradoja en una extensión del lenguaje de la aritmética de primer orden. Particularmente, Priest (1997) y Cook (2006, en prensa) formularon argumentos contenciosos a favor de la circularidad. los objetivos de esta nota son (i) señalar que la noción de circularidad utilizada hasta el momento en el debate es defectuosa, (ii) ofrecer una nueva noción parcial adecuada y útil de circularidad y (iii) mostrar que existe una formulación no circular de la lista en una extensión del lenguaje de la aritmética de primer orden de acuerdo con la nueva noción.

De acuerdo con Shapiro , el deflacionismo debe buscar la conservatividad de sus teorías de la verdad sobre cualquier teoría base. De lo contrario, la noción de verdad que ellas presentan daría lugar a más afirmaciones acerca de la ontología de la teoría base que ésta misma. Así, la verdad tendría poder explicativo y, por tanto, sería en algún sentido una noción metafísicamente sustantiva. El objetivo del artículo es rechazar esta tesis para algunas teorías de la verdad cuyos axiomas son (...) instancias del esquema Tde Tarski, mostrando que las causas de la no conservatividad de estas teorías respecto de teorías base no descansan en sus principios de la verdad sino en la necesidad de introducir en el lenguaje de la teoría base y en su ontología los objetos de los cuales tiene sentido predicar verdad, previamente a la adopción de cualesquiera principios para el predicado veritativo. Shapiro argues that deflationist theories of truth must be conservative over any base theory. For otherwise the principles of truth involved in them would state more about the ontology of the base theory than the base theory itself. Then, truth would have explanatory power, and the deflationist would tie herself down to a substancial notion. The aim of this paper is to argue against Shapiro’s thesis, showing that the real causes of the non-conservativeness of those deflationist theories whose axioms are given by some restricted vesion of the T-scheme do not rely on their truth principles at all. On the contrary, non-conservativeness in these cases depends on the need to add to the language of the base theory those objects than may be true, before adopting such and such principles of truth.

El contenido de la presente discusión de Análisis Filosófico surge a partir de diversas actividades organizadas por mí en SADAF y en la UBA. En primer lugar, Roy Cook dictó en SADAF el seminario de investigación intensivo On Yablo's Paradox durante la última semana de julio de 2011. En el seminario, el profesor Cook presentó el manuscrito aún sin finalizar de su libro The Yablo Paradox: An Essay on Circularity, Oxford, Oxford UP, (en prensa). Extensas y apasionantes discusiones ocurrieron durante (...) esos encuentros sobre circularidad y construcciones infinitarias. Fue en ese tiempo, donde me surgió la idea de editar una discusión sobre las ideas que Cook defiende en ese trabajo. El proyecto era una extensión natural del trabajo que veníamos realizando con mi grupo de investigación en temas vinculados al concepto de verdad, autorreferencia y paradojas. Luego, durante el segundo cuatrimestre de 2011, dicté el seminario La paradoja de Yablo, en el instituto de filosofía de la UBA. Algunos de los borradores de los artículos que aparecen en el presente volumen tienen su origen en este curso. Finalmente, invité por segunda vez al profesor Cook al Symposium on Yablo's Paradox realizado en SADAF en julio de 2012. En esta oportunidad, se presentaron las versiones finales de los artículos de Lavinia Picollo, Paula Teijeiro, Federico Pailos, Diego Tajer, Lucas Rosenblatt e Ignacio Ojea que se incluyen a continuación. El encuentro incluyó las inteligentes réplicas del profesor Cook y profundas discusiones sobre los mencionados temas lógicosemánticos. Quiero agradecer a todos los integrantes del Gaf[log] que participaron activamente en las mencionadas actividades, ya sea en la publicación posterior o en los coloquios y seminarios que le dieron origen. Agradezco al Comité editorial de Análisis Filosófico, en especial a Alberto Moretti, quienes apoyaron desde sus comienzos este proyecto. Finalmente, y de manera especial, quiero expresar mi gratitud al profesor Roy Cook, quien no sólo apoyó e inspiró el proyecto desde sus comienzos, sino que además compartió generosamente sus ideas y las discutió con estimulante pasión.

El presente artículo tiene como objetivo invitar a reflexionar sobre la obra de una filósofa que representa uno de los pensamientos más originales del quehacer filosófico español: María Zambrano. Sus planteamientos en torno a la crítica cultural y género, la crítica al pensamiento moderno, son en sí, una clara crítica a la razón patriarcal. Repensar el quehacer político-práctico de María Zambrano como una figura de la emancipación nos permitirá entender nuestro propio presente.

This paper proposes a philosophical-literary interpretation of the work of Rainer Maria Rilke, carried out, fundamentally, from: Duino Elegies and Sonnets to Orpheus. It is suggested that the Rilkean work contains a proposal for a solution to the existential problem of man in the world, in the context of the crisis of modernity. The poet describes a way to achieve a new human root, whose fundamental axis is the acceptance of death, which is materialized in the acquisition of awareness (...) of one’s own body and its finitude, based on sensitive experiences.

Mit rund 1600 Teilnehmern und über 400 philosophischen Vorträgen fiel er, auch durch den Veranstaltungsort bedingt, wesentlich umfangreicher aus als der XXI. Kongress in Essen.

Escribir hoy en día un libro sobre hermenéutica, que tal hermenéutica se refiera a la desarrollada por G.

The Freud Wars offers a comprehensive introduction to the crucial question of the justification of psychoanalysis. Part I examines three powerful critiques of psychoanalysis in the context of a recent controversy about its nature and legitimacy: is it a bankrupt science, an innovative science, or not a science at all but a system of interpretation? The discussion makes sense of the entrenched disagreement about the validity of psychoanalysis, and demonstrates how the disagreement is rooted in the theoretical ambiguity of the (...) central concept of psychoanalysis, the unconscious. This ambiguity is then presented as the pathway to a new way of understanding psychoanalysis, based on a mode of thinking that precedes division into mental and physical. The reader is drawn into a lively and thought-provoking analysis of the central issues: · What would it mean for psychoanalysis to count as a science? · Is psychoanalysis a form of hermeneutics? · How can mental and physical explanations coincide? Part II contains the source material for Part I: the influential critiques of psychoanalysis by Adolf Grünbaum, Thomas Nagel and Jürgen Habermas. No specialised knowledge is assumed, and the book is clear and accessible while still conveying the complexity and richness of the subject. It provides a fascinating introduction to philosophical thinking on psychoanalysis for students and practitioners of psychoanalysis, psychotherapy and philosophy. (shrink)

In the age of web 2.0, the university is constantly challenged to re-adapt its ‘old-fashioned’ pedagogies to the new possibilities opened up by digital technologies. This article proposes a rethinking of the relation between university and (digital) technologies by focusing not on how technologies function in the university, but on their constituting a meta-condition for the existence of the university pedagogy of inquiry. Following Ivan Illich’s idea that textual technologies played a crucial role in the inception of the university, we (...) will first show the structural similarities between university thinking and the text as a profanation of the book. Secondly, we describe university thinking as a type of critical thinking based on the materiality of the text-on-the-page, explaining why the text has been at the centre of university pedagogy since the beginning. In the third part, we show how Illich came to see the end of the culture of the text as a challenge for the university, by describing the new features of the text-as-code incompatible with the idea of reading as study. Finally, we challenge this pessimistic reading of Illich’s and end with a call for a profanatory pedagogy of digital technologies that could mirror the revolutionary thinking behind the mediaeval invention of the text.

RESUMEN Partiendo de algunas experiencias del presente, se retoma la interpretación nietzs cheana del resentimiento para explorar la complejidad y ambivalencia del fenómeno e iluminar cuestiones actuales. Así, se vinculan dos tendencias y sus implicaciones: cómo el resentimiento genera la fijación de una identidad amenazadora que lleva a la estigmatización de un otro, a la vez como una forma de rechazo de la contingencia histórica; y cómo el vínculo del resentimiento con la temporalidad, en particular con un tipo de memoria, (...) produce una incapacidad para asumirla creadoramente. Esta reflexión deja abiertas preguntas sobre cómo los cuerpos afectados por el resen timiento pueden revertirlo y dar lugar a formas más vitales de relación con el mundo. ABSTRACT On the basis of selected experiences from the present, the article revisits the Nietzschean interpretation of resentment in order to explore the complexity and ambivalence of the phenomenon and shed light on current issues. To that effect, it connects two tendencies and their implications: the manner in which resentment generates the fixation of a threatening identity that leads to the stigmatization of an other, which, at the same time, involves a rejection of historical contingency; and the manner in which the link between resentment and temporality, in particular with a type of memory, produces an incapacity to assume it creatively. This reflec tion leaves questions open regarding how bodies affected by resentment can twist it around and give rise to more vital forms of relating to the world. (shrink)
