This paper proposes to reconstruct Boaventura de Sousa Santos' conception of "epistemologies of the south" both (a) as a critical theory aiming at denouncing the impoverishment of the epistemic field entailed by the normative imposition of a certain model of knowledge (what we call "the monoculture of reason"), and (b) as a long-term political project of a harmonic coexistence of different epistemologies ("an ecology of knowledges").

The aim of this article is to advance the idea according to which the Cartesian Cogito, the ground of modern philosophy and the source of the notion of thinking subject, is tributary of a certain method whose legitimation is grounded in western history. According to this hypothesis, there is a certain tool that plays a fundamental role in the production of this new philosophical notion: the dream. The argument will be developed in four parts. We will first proceed to (i) (...) an analysis of the role of the hypothesis of the dream in the formulation of the notion of res cogitans, what will bring us to (ii) an exploration of the conception of private world supposed by such a hypothesis so as to (iii) clarify the specificity of the Cartesian notion of knowledge, a knowledge that must be acquirable in a dream; in conclusion (iv) we will indicate in a schematic way the historic-cultural anchor of the Cartesian dream where the subject is originated.

This article advances the hypothesis that the Fichtean enterprise of grounding all possible experience in a fundamental principle has to fail in order to succeed one of its most important tasks: reformulating the very idea of subjectivity. In order to ground this hypothesis, the paper will be divided in four parts: (i) the first one will analyze the starting point of the work where Fichte lays the foundations of his philosophical project (Grundlage der gesamten Wissenschaftslehre) so as to show that (...) its first principle contains a fundamental ambiguity. We will then (ii) suggest that this very ambiguity reveals itself in the Anstoß, the conceptual tool through which Fichte intends to get rid of the Kantian notion of thing-in- itself. In a third moment (iii), we will explore the effects of this abandonment of the thing-in-itself on the relation between the finite and the infinite, what will bring us to the notion of failure. Finally (iv), we will propose to interpret this failure as a positive driving force of a permanent calling into question of the subject and its language. (shrink)

This paper explores the contrast between two meanings of thinking: (i) one implied by the Cartesian and Kantian philosophy, the two thinkers that have arguably the deepest influence on the constellation of Western philosophical problems and (ii) another implied by the philosophical-anthropological project of the Brazilian anthropologist Eduardo Viveiros de Castro. The thesis here defended is that, in the Cartesian and Kantian philosophy, thinking is related to ruling and legislating over the experience through concepts, while in Viveiros de Castros' theoretical (...) enterprise, thinking is rather to explore the limits of conceptual constructions when confronted with the experience of alterity.

The purpose of this paper is to examine the peculiarity of what Aristotle named practical wisdom or practical knowledge. Pivot to our analysis is the first thesis of the Nicomachean Ethics, where the philosopher appears to state a fallacy when he argues that, given that all actions aim at some good, good is that which every action aims to. We argue that the inference is non-fallacious because of the peculiarity of the practical domain, which manifests itself in the identity of (...) the good and the end. This identity is in the origin of what we would call, as an hypothesis, practical significance. (shrink)

This paper claims that the inner drive of the discussion leading to the philosophical rupture between Fichte and Schelling is the problem of the independence of nature. I argue that the otherwise rich literature on the subject, by not engaging with this problem, has led to a false dichotomy between two equally unsatisfactory possibilities of interpretation: Schelling’s misunderstanding of Kant’s transcendental method or his overcoming of it. On my account, once one engages with Schelling’s philosophy of nature, it becomes clear (...) that he, just as Fichte, is exploring the inner tensions of Kant’s philosophy, even though he does it in a different and original direction. (shrink)

Counteracting a widespread interpretation of Schelling’s project of a philosophy of nature as anti-Kantian, this paper claims that Kant’s doctrine of the schematism plays a central role in the emergence and development of Schelling’s project. My argument will be structured in the following way. First, I will discuss Schelling’s reception of the schematism in his Ideas for a Philosophy of Nature of 1797, especially as regards his association of it with Kant’s dynamical conception of matter in the Metaphysical Foundations of (...) Natural Science. Relying on this reconstruction, I will argue, secondly, that Schelling brings together a central issue of the Critique of Pure Reason (the objectivity of pure concepts) and the overall problem of the Metaphysical Foundations (the transition from pure philosophy to empirical sciences) by addressing the issue of a schematism specifically related to outer sense. Thirdly, I maintain that this issue is at the core of the overall argument developed in the Ideas, where it appears in the form of a schematism of “materiality as such”. Finally, I suggest that the notion of a schematism of materiality as such offers a useful key to understanding the unfolding of Schelling’s project between 1797 and 1800. (shrink)

Independently of the discussions on the development of Fichte’s philosophy, there is something that does not seem to change throughout the more than a dozen presentations of his doctrine, namely, his constant concern with the meaning of philosophy. This concern is such a structuring one for Fichte that he even decides to replace the very name of “philosophy” by another one, less heavy in meaning and better suited to elucidate the nature of this particular activity that constitutes his own project. (...) He calls it the Wissenschaftslehre. In this term created by Fichte three verbs can be found: wissen (to know), schaffen (to create) and lehren (to teach) – we would like to propose that Fichte’s conception of philosophy can be brought out as the orchestrated action of those three activities: knowing, creating and teaching. The point here being not to say that Fichte had the idea in mind of composing these three verbs (wissen, schaffen, lehren) when he created the term Wissenschaftslehre, but only that those terms offer useful landmarks for the exploration of Fichte’s philosophical landscape. -/- .

Resumo: Este artigo é um exercício de leitura comparada dos textos Reden an die deutsche Nation, publicado por Johann Gottlieb Fichte, em Berlim, em 1808, e Crítica da razão tupiniquim, publicado por Roberto Gomes, em São Paulo, em 1977. Se, à primeira vista, os dois universos de discurso parecem tão distantes que dificilmente se vê o que os aproxima, parece haver contudo uma flama comum que os anima, na medida em que ambos buscam evitar o aprisionamento do espírito local nos (...) grilhões de um universo simbólico que não é o seu. O objetivo deste estudo é explorar cada uma das obras, em seus respectivos contextos, a fim de delinear os aspectos dessa chama comum que as motiva; após a confrontação dos dois textos, far-se-á, como conclusão, um breve esboço dos possíveis ganhos dessa abordagem comparativa.: This article is an exercise in the comparative reading of the Fichte’s Reden an die deutsche Nation, published in Berlin in 1808, and Robert Gomes’ Crítica da razão tupiniquim, published in São Paulo in 1977. At first glance, the two universes of discourse appear to be so distant as to render considerably difficult any kind of comparison. However, they seem to be animated by a common spirit inasmuch as both are essays that articulate an epistemological resistance to the imminent danger of being enclosed in a symbolic universe that bears no contact with their own socio-political realities. The aim of this study is to explore each text in its respective context, so as to delineate the main aspects of their commonality. After the comparing the texts, we say a brief word in conclusion on the relevance of this comparative approach. (shrink)

Résumé L’article vise à souligner la signification politique de l’avènement de la Critique kantienne. Pour ce faire, une double thèse est défendue : il y a une matrice juridique sous-jacente au mouvement conceptuel de la philosophie critique, dont la puissance émancipatrice et révolutionnaire se manifeste à la lumière du contexte historique de sa formulation. L’argument se déploie de la façon suivante : une exploration des rapports entre la formule « révolution de la pensée » que l’on trouve dans la Critique (...) de la raison pure et le contexte historique de la publication l’œuvre ; ensuite un examen de la métaphore juridique et la façon dont elle incarne l’idée d’une philosophie critique ; et pour conclure la suggestion d’une hypothèse interprétative d’après laquelle le « contrat originaire » est un opérateur conceptuel accomplissant un mouvement analogue à celui qui est exigé de la philosophie critique : le passage du niveau individuel au niveau intersubjectif.The aim of the article is to highlight the political significance of the advent of Kant’s Critique. In order to establish it, a double thesis is defended: there is a juridical matrix underlying the conceptual movement of the critical philosophy, whose emancipatory and revolutionary strength is revealed in the light of the context of its formulation. The argument will be deployed in the following way: an exploration of the connections between the formula “a revolution in thought” articulated in the Critique and the historical context of its publication; followed by an exam of the juridical metaphor of the Tribunal and the way in which it embodies the idea of a critical philosophy and finally, as a conclusion, the suggestion of an interpretative hypothesis according to which the notion of contract is a conceptual operator accomplishing an analogous movement to the one required from the critical philosophy: the passage from the subjective level to the intersubjective one.

Cet article montre que Fichte développe une originelle conception du langage dans ses Discours à la Nation allemande d’où il ressort non seulement le besoin de retraduire des concepts philosophiques dans un langage populaire comme aussi celui de formuler un langage plus malléable pour la philosophie en tant que telle. Afin d’explorer cette hypothèse, notre propos suivra les étapes suivantes : (i) nous analyserons la conception fichtéenne du rapport entre popularisation et flexibilisation du langage, ce qui nous permettra (ii) d’explorer (...) les raisons systématiques du rapprochement entre langue philosophique et langue populaire et (iii) de saisir précisément la compréhension du rôle philosophique du langage qui en découle.

This paper advances the idea that Oswald de Andrade's Anthropophagy, formulated for the first time in 1928, can be read as a decolonial project avant la lettre. In order to establish this thesis, we will reconstruct the project of the Brazilian thinker through a detailed analysis of the first aphorism of his Manifesto Antropófago (Anthropophagist Manifesto). We will argue that, similarly to what will be later articulated by the decolonial approach, Andrade indicates: (i) that the cultural and economic dimensions of (...) colonialism are entangled ramifications of a larger structure of domination; (ii) that capitalism is an aspect of this larger structure; and (iii) that it is necessary to articulate a third political path irreducible to both capitalism and communism. Anthropophagy would thus function not only as the evident metaphor of cultural appropriation, but also as a diagnosis of the colonial domination and as a therapeutic to face it within a decolonial project.

Das Ziel dieses Beitrages ist es, zu zeigen, wie das cartesianische Cogito ,der Boden der modernen Philosophie, das im Begriff des denkenden Subjekts – einem Schlüsselbegriff des westlichen Denkens – seinen Ursprung hat, von einer ganz bestimmten Methode, deren Legitimation in der Geschichte wurzelt, abhängig ist. Anders ausgedrückt, der Begriff des Subjekts, dessen grundlegendes Merkmal die Denktätigkeit ist, und der die Geschichte, eben weil er Begriff ist, hinnehmen muss, ist durch die Geschichte bedingt – durch eine Geschichte, die sich weniger (...) im Begriff selbst als in der ihn ermöglichenden Methode ausdrückt. Eine genaue genealogische Studie dieserMethode würde eine äußerst gründliche Arbeit erfordern; was wir hier viel-mehr unternehmen wollen ist lediglich, die von Descartes benutzten methodologischen Werkzeuge zu erforschen, die für die Formulierung des Begriffs Res Cogitans (die nach Kants Kritik zum „Subjekt“ wurde) vonnöten waren. Ein Werkzeug spielt laut der hier verteidigten Annahme eine besonders grundlegende Rolle in der benannten Diskussion um Res Cogitans : der Traum Descartes. (shrink)

Este estudo é uma exploração da concepção de lógica como uma “história pragmática da alma [pragmatische Seelengeschichte]”, tal como ela é formulada pelo médico e filósofo alemão Ernst Platner. Da análise dessa fórmula, pretende-se extrair um esboço do modo como ele concebe as noções de: alma, história, lógica e filosofia. Para tanto, o argumento será estruturado como uma análise: da alma enquanto objeto de estudo da lógica; da história pragmática enquanto método de estudo da lógica; e da compreensão da relação (...) entre lógica e filosofia extraída por Platner dessa abordagem. O objetivo deste trabalho não é fazer uma avaliação crítica da teoria de Platner, mas antes fazer um esboço do horizonte de questões que se abre a partir dessa compreensão da porta de entrada da filosofia – a lógica – como uma espécie de história da alma.

Este artigo argumenta que Fichte, nas primeiras formulações de seu projeto filosófico, apreende a tarefa da filosofia não tanto como uma Crítica da Razão, mas antes como um Autoconhecimento do Espírito, trazendo assim a noção de Espírito para o centro da discussão filosófica. Exploramos o que Fichte entende por Espírito e argumentamos que essa noção, ainda que ela não seja usada de modo consistente ao longo de sua obra, cobre um espaço conceitual fundamental do projeto filosófico fichtiano. O argumento será (...) estruturado como uma exploração de cada uma das dimensões desse espaço, a saber: o Espírito como auto-‑relação; o Espírito como imaginação produtiva; e o Espírito como o resultado do processo de aprendizado fundado nos impulsos humanos.

Ce travail avance l’idée que le projet philosophique fichtéen consiste en une exploration de la notion même de philosophie dont les contours peuvent être esquissés à partir du remplacement du nom "Philosophia" par le nom Wissenschaftslehre. Cette substitution est le fruit d’une réflexion sur les conditions de possibilité non seulement de la connaissance scientifique, mais aussi du savoir philosophique en tant que tel, lequel doit être compris non comme un rapport sujet-objet, mais comme une activité autoréflexive visant à articuler une (...) vision systématique du tout. Une telle conception pose un défi au langage philosophique, en ceci qu’il ne saurait être conçu comme un langage représentatif et qu’il devient par là, selon Fichte, irréductible à un texte écrit ; face à ce défi, il est nécessaire de constamment réactiver le philosopher derrière les concepts, ce que Fichte fait, selon nous, en présentant sa philosophie dans différentes langues conceptuelles. Le constant éveil de cette activité dépend pourtant d’un travail pédagogique visant à : (i) rapprocher la langue savante de la langue quotidienne, (ii) engendrer une conscience historique et (iii) établir un espace d’apprentissage collectif.

Among the manuscripts of Ovid's Metamorphoses used by N. Heinsius and as yet unidentified or given up for lost is the so-called fragmentum Caesenas, the collation of which was not carried out by Heinsius himself but provided for him by the Hamburg jurist Lucas Langermann, who was a correspondent of Heinsius, Gronovius and Vossius, among others. According to M.D. Reeve, he was also responsible for adding these notes, using the siglum c, to Oxon. Bodl. Auct. S.V.5, which also includes the (...) collations—by another hand—of A and B. The variants provided by this fragment affect lines 9.235–11.169 and 13.1–403, although this does not imply that these were the exact limits of its content, as we shall see below. Some of these variants ended up in the notes of the editions by Heinsius himself and by those who continued his work, and it was D.A. Slater who rescued the collation of Bodl. Auct. S.V.5 from obscurity when he included the greater part of the readings of c among the rich store of information presented in his work. F. Munari included the fragment in his catalogue, clearly pointing to the uncertainty surrounding its dating while adding the information that it was not at that time to be found in Cesena. The succinct information offered by Slater is used by I. Marahrens for her dissertation and by W.S. Anderson for his edition. R.J. Tarrant, in turn, explicitly states that the fragment is now lost. In the following pages, however, I will attempt to show that this fragment is not lost, but still preserved in the Biblioteca Malatestiana in Cesena. (shrink)

Une grande stèle trouvée à Larissa en 1990 porte trois décrets votés par cette cité au cours de la même année, probablement très peu après la fin de la troisième guerre de Macédoine, donc en 171/0 av. J.-C. ou l'une des années suivantes. Les deux premiers honorent un philosophe athénien, Satyros fils de Philinos, qui a séjourné sans doute plusieurs années à Larissa et y a vécu les temps de guerre : le peuple de Larissa le récompense en lui accordant (...) la proxénie et différents honneurs, complétés par l'octroi du droit de cité, qui fait l'objet d'un décret complémentaire. Le troisième décret a été voté pour un Mamertin de Sicile appelé Novius fils d'Ovius, qui a racheté un Larisséen capturé par des soldats romains au cours de la même guerre et l'a rendu à la liberté. Dans la partie disparue au bas de la stèle, un quatrième décret devait, comme pour le philosophe Satyros, accorder à Novius le droit de cité. Ces textes sont de tout premier ordre à la fois parce qu'on y trouve des formulaires très explicites et complets, ce qui est peu fréquent, et parce que leur rédaction, dans un dialecte cohérent et représentatif, donne matière à des observations syntaxiques et stylistiques qu'il n'est pas toujours possible de faire sur d'autres documents thessaliens. Leur valeur pour l'histoire de Larissa n'est pas moindre, puisque l'on peut rassembler autour de ces textes plusieurs autres documents déjà connus qui se rapportent à la troisième guerre de Macédoine, soit aux quelques années qui l'ont précédée, soit aux années 171-169 av. J.-C. et à celles qui ont immédiatement suivi. (shrink)

The most popular conceptions of democratic legitimacy incur in serious difficulties in dealing consistently with two dimensions of democratic legitimacy which seem to be naturally associated with it: the procedural dimension, associated with the fairness of the decision making process; and the epistemic dimension, associated with the correction of the outputs. In this paper I argue that such tension arises from the adoption of a “veritistic-consequentialist” social epistemology; it is possible to deal with that tension by replacing this problematic epistemological (...) conception with a pragmatist procedural social epistemology, and c) such replacement leads institutional design to an experimentalist orientation.

The practice of physical activity (PA) contributes to the prevention of chronic diseases such as obesity, metabolic syndrome or cardiovascular diseases, being also directly related to the individual’s physical fitness. Therefore, it is necessary to measure and monitoring the levels of PA in childhood and adolescence, since it may be useful to describe their current health status and the association with physical fitness, as well as to reveal putative consequences in the future. Within the educational field, it has been shown (...) that physical education (PE) classes are a favorable context for the creation of healthy physical-sports habits and self-determined motivation could be a key for explaining the level of PA practice. For this reason, the purpose of this research was to study the mediating role of integrated regulation (IR) on the relationship between PA and physical fitness in children and adolescents. A total of 325 students between 11 and 14 years old participated in the study. The level of PA was estimated through the specific Physical Activity Questionnaire for Children (PAQ-C), while motivation and IR were measured by using the Perceived Locus of Causality scale (PLOC-2). In addition, physical fitness was measured through the Eurofit fitness battery of tests, composed of three body composition measures and seven tests of different physical capacities. The physical fitness score showed no differences when genders were compared. After regression analysis, the resulti... (shrink)

La tesis central de este trabajo es que la tradicional tensión entre substancia y procedimiento socava las estabilidad de la justificación de la concepción liberal más extendida de la legitimidad (la Democracia Deliberativa). Dicha concepciones enfrentan problemas serios a la hora de articular de manera consistente dos dimensiones que parecen ir naturalmente asociadas a la idea de legitimidad: la dimensión procedimental, vinculada a la equidad del procedimiento, y la dimensión epistémica, asociada a la corrección de los resultados. En este trabajo (...) sostengo que a) esa tensión surge de la adopción de una concepción epistemológica social de tipo "veritativo-consecuencialista; b) es posible manejar dicha tensión mediante el remplazo de la epistemología subyacente por una concepción epistemológica social de tipo procedimentalista de orientación pragmatista y c) dicha operación orienta el diseño institucional en una dirección experimentalista.

Within ordinary ---unitary--- quantum mechanics there exist global protocols that allow to verify that no definite event ---an outcome to which a probability can be associated--- occurs. Instead, states that start in a coherent superposition over possible outcomes always remain as a superposition. We show that, when taking into account fundamental errors in measuring length and time intervals, that have been put forward as a consequence of a conjunction of quantum mechanical and general relativity arguments, there are instances in which (...) such global protocols no longer allow to distinguish whether the state is in a superposition or not. All predictions become identical as if one of the outcomes occurs, with probability determined by the state. We use this as a criteria to define events, as put forward in the Montevideo Interpretation of Quantum Mechanics. We analyze in detail the occurrence of events in the paradigmatic case of a particle in a superposition of two different locations. We argue that our approach provides a consistent single-world picture of the universe, thus allowing an economical way out of the limitations imposed by a recent theorem by Frauchiger and Renner showing that having a self-consistent single-world description of the universe is incompatible with quantum theory. In fact, the main observation of this paper may be stated as follows: If quantum mechanics is extended to include gravitational effects to a QG theory, then QG, S, and C are satisfied. (shrink)

Resumen: Este artículo trata del método y su relación con la investigación educativa. El objetivo es analizar la relevancia del método en ciencias humanas y sociales, en especial, en educación. Para ello, dividimos este artículo en tres secciones: 1. ¿Hay método? 2. ¿Hay uno o varios métodos? 3. La discusión sobre el método en la investigación educativa. A la primera pregunta, respondemos que hay método. Respondemos a la segunda señalando la necesidad de adoptar un pluralismo metodológico. La tercera sección defiende (...) que las discusiones sobre el método de investigación educativa implican dimensiones ontológicas, epistemológicas y éticas que se han tornado críticas, y se hace una revisión de cada una de ellas. En el apartado conclusivo, sugerimos algunas vías para desanudar esos asuntos críticos en la investigación educativa.: This article deals with method and its relation to educational research. The objective is to analyze the relevance of method in human and social sciences, especially in education. To this end, we divide this article into three sections: 1. Is there a method? 2. Is there one or more methods? 3. The discussion on method in educational research. To the first question, we answer that there is a method. We answer the second question by pointing out the need to adopt methodological pluralism. The third section argues that discussions on the method of educational research involve ontological, epistemological, and ethical dimensions that have become critical, and a review is made of each of them. In the concluding section, we suggest some ways to disentangle these critical issues in educational research. (shrink)

Le travail mené par Jonathan Israel dans sa trilogie sur les Lumières aurait fourni des éléments pour une critique de la théologie comme fondement de la politique moderne et, de ce fait, il nous aurait offert une critique indirecte à l’œuvre de Carl Schmitt. Schmitt et Israel souscrivent à l’analyse des idées majeures que Spinoza hérite de la modernité. En revanche, ils ne s’entendent pas sur l’appréciation de cette contribution ni sur le sens qu’il faut donner à cet héritage. Tandis (...) que Spinoza s’avère être l’ennemi par excellence pour Schmitt – juif, libéral et paradigmatique −, il représente pour Israel le pilier du républicanisme démocratique; alors que pour le premier le pêché originel implique l’acceptation d’une anthropologie modérément pessimiste qui fondait la nécessité de l’État, le second assure que le perfectionnement humain et l’idée de progrès sont possibles ; tandis que Schmitt justifie l’existence de la guerre et du concept de katechon en tant que piliers politiques, pour Israel la tolérance universelle d’origine baylienne se pose comme alternative ; si Schmitt considère que le dialogue et le débat constituent de simples distractions bourgeoises qui empêchent de distinguer la véritable nature de la souveraineté – la décision dans un état d’urgence –, Israel estime quant à lui que la dialogue rationnel et philosophique qui suppose la revendication de la liberté de philosopher est la seule forme acceptable pour concevoir des normes morales et politiques ; si le juriste allemand attribue à la théologie catholique l’origine de tout concept politique – au sens historique et systématique –, pour l’historien anglais c’est plutôt dans la philosophie rationnelle matérialiste énoncée par les acteurs des Lumières radicales qu’il faudrait chercher les fondements de la doctrine politique occidentale républicaine et démocratique.

Teniendo en cuenta que la filosofía es hija de la polis, a primera vista, el tema de la filosofía de la ciudad puede no revelar nada nuevo. De hecho, la filosofía y la ciudad cuentan una historia paralela. Es en el ágora, un espacio privilegiado para el ejercicio de la ciudadanía, donde la filosofía se desarrolla como debate de argumentos. Pero, aunque a lo largo de la historia las ciudades puedan reflejar un deseo civilizatorio, lo cierto es que la ciudad (...) contemporánea refleja muy poco de la realidad política de la polis, de la indiferenciación medieval entre lo público y lo privado o de la racionalidad normativa de la ciudad moderna. Las ciudades en el siglo xx, y especialmente en el siglo xxi, tienen que ver más con las relaciones sociales y económicas de la ciudad industrial y posindustrial. La progresiva mecanización del siglo xix y su extensión, en el siglo xx, a la automatización y a la digitalización, cambian definitivamente la forma en que nos relacionamos, pensamos y trabajamos —en resumen, cómo vivimos—. Con el establecimiento de un capitalismo de orden económico que afecta a todas las dimensiones de la vida de la ciudad, esta queda delimitada por el poder, revela las contradicciones de las sociedades urbanas diseñadas por los mercados y da lugar, según David Harvey, a la apropiación privada de la vida y los espacios.

An analysis of the extension of the Hawking-Penrose singularity theorem to Riemann-Cartan U4 space-times with torsion and spin density is undertaken. The minimal coupling principle in U4 is used to formulate a new expression for the convergence condition autoparallels in Einstein-Cartan theory. The Gödel model with torsion is given as an example.
