This article analyzes the interpretation proposed by Michel Foucault of the Iranian Revolution, i.e. the popular uprisings and revolts that took place in Iran in 1978 and their consequences in the formation of the Islamic Republic in 1979, with the aim of systematizing the thought of the philosopher about this question and of going further in a highly potent matrix in his production which unfortunately has been partly eclipsed by the shallow and hasty criticisms it received. For this purpose, I (...) will proceed to the exam of the problematic cores and the conceptual categories arising from what can be called Foucault’s dossier Iran accounting for the relationship between the subject, politics and history. Likewise, I will highlight the main axes of that interpretation following the link with the researches and central lines that Foucault is developing at that moment, in particular, the relationship he establishes between life, government and truth and the reformulation of the problem of power in terms of the problem of government which will enable him to deploy that aspect of his analyses of power and politics relating to resistance, freedom and the critique of the present. Finally, I will propose an assessment in perspective, underlining the scope and the potentialities of the Foucauldian ideas about these events. (shrink)

Este artículo analiza la noción de vida del paradigma biopolítico foucaultiano a partir de una bivalencia fundamental de la vida, entendida tanto como correlato de un poder que la domina y la administra, como posibilidad de un poder que resiste y que escapa siempre también a las tecnologías biopolíticas y se enfrenta a ellas. Ahora bien, ¿de dónde extrae Foucault esas virtualidades de la vida?, ¿con qué materiales construye ese concepto? y sobre todo, ¿qué alcances y potencialidades tiene? El análisis, (...) que toma en consideración la producción foucaultiana en su conjunto así como el aparato crítico sobre esta problemática, destaca y se centra, en particular, en el ascendente nietzscheano, lo que tendrá consecuencias de importancia para comprender desarrollos ulteriores sobre la vida en el pensamiento del filósofo francés, como la estética de la existencia, la resistencia, la crítica y la libertad. Con el fin de llevar a cabo este trabajo, el artículo se estructura a partir de los siguientes puntos: una breve revisión de la noción de vida al interior de la producción foucaultiana en su conjunto; el análisis de la noción de vida que Foucault presenta hacia mediados de los años 1970 en lo que se podría denominar el “paradigma biopolítico” y, en particular, en su relación con las nociones de poder y de gobierno; el examen de la genealogía entre las nociones de vida y de poder del paradigma biopolítico foucaultiano y la noción nietzscheana de “voluntad de poder”; y la propuesta de un conjunto de conclusiones tentativas de la noción de vida en el paradigma biopolítico foucaultiano, destacando una serie de alcances y potencialidades del componente de la resistencia de esa noción.

Este artículo pretende analizar la particular relación de imbricación que Michel Foucault y Giorgio Agamben han venido a establecer entre la vida humana y el poder. A tal fin, se propone un recorrido por los dos momentos centrales de su producción que permiten dar cuenta de dicha imbricación: en el caso de Agamben, el referido a la investigación “homo sacer” y, en el de Foucault, el de su investigación en torno de la biopolítica como acontecimiento decisivo de la modernidad. Ambas (...) investigaciones han redundado, entre otros aspectos, pero de manera central, en la configuración de la vida humana en su relación con el poder. En cada uno de los momentos elegidos en las producciones de los filósofos, se analizan las nociones centrales que componen cada investigación: nuda vida, “homo sacer”, estado de excepción y “oikonomía”, en el primer caso; y biopolítica y gubernamentalidad, en el segundo. Finalmente, se contrastan ambas formulaciones filosóficas a fin de sopesar los alcances y las potencialidades que implican frente al análisis que proponen. Este breve ejercicio de análisis sobre la relación entre la vida y el poder en los dos filósofos, pretende poner en evidencia los riesgos a los que nos exponen ciertos presupuestos frecuentes que fundamentan y dan sentido a las ideas y a las prácticas políticas contemporáneas.

Este artículo analiza las ideas que Foucault produjo sobre la cuestión del racismo con el fin de evaluar sus alcances y potencialidades para seguir pensando hoy esa problemática, para interactuar con ella, pero también para discutir con esa perspectiva y para revisar las transmutaciones, los trastocamientos y las nuevas configuraciones que el racismo puede asumir actualmente. El desarrollo argumental se estructura a partir del examen de los siguientes puntos: la noción de racismo elaborada por Foucault y su complementaria de racismo (...) de Estado, como transformaciones fundamentales de la idea de la guerra de razas y del discurso de la contra-historia y como epifenómenos de la biopolítica; el modelo de la guerra, el discurso de la contra-historia y la guerra de razas como los antecedentes que, en el análisis foucaultiano, llevaron, en el interior de las sociedades y los Estados europeos, pero también en una relación inescindible con los sistemas de clasificación y jerarquización social de las colonias, a la idea de racismo, o al menos, a un cierto desarrollo paradigmático de aquello que concebimos como racismo; y finalmente, una serie de conclusiones tentativas acerca de las ideas que Foucault propone para abordar y analizar el racismo, sopesando los alcances y las potencialidades de esas ideas.

Dans cet article je me propose d’analyser dans quelle mesure les droits humains peuvent constituer un outil d’émancipation et de construction de nos démocraties compte tenu des critiques fortes qui leur ont été adressées depuis le XIXe siècle et notamment au cours du XXe siècle, en particulier, à partir du paradigme dit postmoderne. Plus spécifiquement, j’essaierai de répondre à cette question à partir de la position foucaldienne à l’égard de la production de droits, notamment de ce que le philosophe appelle (...) les « droits des gouvernés », liés, dans sa production, à la notion de « nouveau droit », comme stratégie de résistance et comme « pratique de liberté ». Ma réponse sera également orientée, en dernière instance, par le besoin d’examiner la potentialité et la portée des droits humains dans l’arène politique actuelle. (shrink)

Esta ponencia pretende hacer explícita la particular relación que Michel Foucault y Giorgio Agamben postulan entre la vida y el poder como una relación de imbricación por la cual el poder siempre ha dado forma a la vida, en el sentido de lo viviente, apresándola bajo modalizaciones específicas y, por esta vía, propone asimismo una hermenéutica de las formas contemporáneas del sujeto a partir de la relación señalada. A tal fin, se revisará la forma particular en que la vida en (...) tanto zōē o simple vida biológica o animal, se ha imbricado con el poder en Occidente y en particular en la modernidad, para producir determinadas formas humanas en las que la vida en términos de bios o vida calificada por la cultura y la polis, ha quedado, en forma contraria a las declaraciones de principios explícitos de la arquitectura metafísicopolítica, neutralizada. Para ello, se examinarán en especial, los desarrollos de Michel Foucault y de Giorgio Agamben en torno del biopoder y la biopolítica, la nuda vida y las figuras del homo sacer y el estado de excepción y el paradigma de la teología económica.

We examine the most famous controversy between economists as a means of shedding fresh light on the current debate about economic methodology. By focusing on the controversy as the primary unit of analysis, we show how methodological considerations are but one of a whole set of stratagems strategically employed by each opponent. We argue that each opponent's preference for a particular kind of stratagems expresses his own specific scientific style (within the general scientific and cultural style of an age). We (...) also describe a dynamic dimension of the controversy, independent of the participants' intentions. Such a dimension is analysed in a "cycle" of the controversy, which begins with a well-defined issue and expands to additional topics, without reaching a "solution" to the initial issue. The definition and re-definition of the issue(s) at stake and of the difference between both participants is an essential and recurrent feature of such cycles; the conclusion of a cycle does not imply a real "closure" of the controversy, but only that each opponent has reached a satisfying degree of self-clarification. The controversy, thus, does not yield persuasion -- its ostensible aim. Rather, its "benefit" seems to lie in an unintended result -- clarification and deepening of contrasting approaches to the discipline -- due to its peculiar dynamics. In so far as the history of a discipline requires a reconstruction of such contrasts, it is indispensable for it to take into account the controversies where they emerge, and to view both the positive doctrines and the methodological posture of the contenders as parts of a wider framework, that is a scientific style.

Resumen: Dada la multiplicidad de planos que acompañan a las observaciones de la actual pandemia, importa identificar aquellas que alcanzan una mayor resonancia. Así, observamos cómo los ciudadanos y los agentes de decisión han incrementado sus demandas de informaciones validadas por medio de la aplicación de la racionalidad, los métodos y los procedimientos de la ciencia de manera exponencial. En este trabajo desarrollamos en forma sintética un conjunto seleccionado de lineamientos sobre cómo se aborda la actual pandemia desde las ciencias (...) sociales sistémicas, para luego exponer algunas de sus propuestas respecto a las condiciones, a nivel organizacional, las cuales podrían permitir alcanzar los niveles de diálogo y cooperación requeridos para enfrentar la pandemia actual.: Given the multiplicity of perspectives that accompany the observation of the current pandemic, becomes relevant to identify those that achieve the greatest resonance. Thus, it is observed how citizens and decision makers have increased their demands for valid information by applying rationality, methods, and procedures of science in an exponential manner. In this paper we develop a synthetic set of selected guidelines on how the current pandemic is approached from systemic social sciences, and then present some of their proposals regarding the conditions, at the organizational level, which could enable the achievement of the levels of dialogue and cooperation required to address the current pandemic.

The paper is a comparative study of the methodologies of Malthus and Ricardo. Its claims are: (i) economic laws almost always admit of exceptions for Malthus; for Ricardo even contingent predictions allow no exception apart from random temporary variations; (ii) both rely on the prestigious Newtonian paradigm, while interpreting it according to two distinct methodological traditions (the one deriving from MacLaurin, the other from Priestley); (iii) the choice of stressing what happens during intervals or in permanent states leads to opposing (...) definitions of the main problem of economic science in so far as equilibrium is always already given for Ricardo and is never given for Malthus; (iv) their use of the ambiguous notion of "tendency" leaves unclear for both the degree of predictive power with which theories are endowed; (v) what both share is the idea of a natural order and this idea is the source of both shortcomings and endless disagreement. -/- .

Although the controversy between Malthus and Ricardo has long been considered to be an important source for the history of economic thought, it has hardly been the object of a careful study qua controversy, i.e. as a polemical dialogical exchange. We have undertaken to fill this gap, within the framework of a more ambitious project that places controversies at the center of an account of the history of ideas, in science and elsewhere. It is our contention that the dialogical co-text (...) is essential for reconstructing the meaning and the evolution of science. In the present paper we try to substantiate this contention by means of a pragma-rhetorical study of this particular controversy. First, we reconstruct, through an analysis of a chunk of the correspondence, a micro-level of specific moves and countermoves which constitute a sequential structure within which also meta-scientific and meta-controversial considerations play a role. We then move to a macro-level of analysis, looking for recurrent patterns of argumentation. Finally, we draw epistemological conclusions on the nature of rationality and progress as manifested in actual scientific controversies. (shrink)

We reconstruct the text, that is, we analyse the development of the discussion between Malthus and Ricardo both in the correspondence and in published works, paying special attention to (a) the use of methodological statements, (b) some pragmatic features of the controversy, (c) considerations pertaining to the meta-level of the controversy (assessments of the status of the controversy, of ways of solving it, etc.); then, we reconstruct the co-text, that is, unpublished papers by each opponent that were not made available (...) to the other, records of exchanges between each of these and third parties, etc.; thirdly, we describe the essential features of the context, focusing on events that influenced the course of the controversy; (iv) we draw lessons from our case study on the role of co-text and context, on pragmatic and semantic interpretation, and on "casts of mind”.

We reply to Philippe Depoortère’s paper “On Ricardo’s method: The Unitarian influence examined. Some comments on Cremaschi and Dascal’s article ‘Malthus and Ricardo on Economic Methodology’”. Depoortère asks two questions: (1) was Ricardo’s ‘conversion’ to Unitarianism sincere? (2) did Ricardo follow the methodologies of Priestley and Belsham? His answers are that he was a ‘religious skeptic’ and he was not an ‘empiricist’ like Priestley and Belsham. We reply that the sincerity of Ricardo’s religious beliefs is irrelevant since we start with (...) the evidence that he was exposed for a long time to the intellectual influence of Belsham, primarily in matters of philosophy, and to deny this would imply a negative answer to a different question, namely, did Ricardo attend Unitarian meetings for 15 years? Then we reply that Ricardo inherited Belsham’s version of Newtonian methodology which omitted the fourth rule, that is the most anti-Cartesian and anti-systematic rule, and this has little to do with empiricism but instead with apriorism.

This article investigates the existence of an original Brazilian legal culture. It parts from a critical examination of the key moments in the history of Brazil through the accounts of its most important scholars, such as Caio Prado Júnior, Darcy Ribeiro, Sérgio Buarque de Holanda, Wilson Martins, Oliveira Viana, Roberto Damatta, José Murilo de Carvalho, among others. It identifies in the Brazilian legal culture something one might call tradition of exception, which can be found in many of its most prominent (...) aspects, such as the persistent denial of any general or abstract regulatory standards, the uncritical introduction of foreign doctrines and legal patterns, the maintenance of aristocratic traditions in social life and the historical disregard of the Brazilian people as political subject. The article also offers a reflection on the problems and potentials of the current historic moment, in which for the first time Brazilians face the possibility of a genuine cultural emancipation.

Accidie, depression, and dejection seem to be psychological phenomena that are best characterized as cases in which an agent has no motivation to pursue what he or she judges to be good or valuable. The phenomena thus seem to present a challenge to any view that draws a close connection between motivation and evaluation. ‘Accidie, Evaluation, and Motivation’ aims to show that the phenomena are actually best explained by a theory that postulates a conceptual connection between motivation and evaluation.

Multialgebras have been much studied in mathematics and in computer science. In 2016 Carnielli and Coniglio introduced a class of multialgebras called swap structures, as a semantic framework for dealing with several Logics of Formal Inconsistency that cannot be semantically characterized by a single finite matrix. In particular, these LFIs are not algebraizable by the standard tools of abstract algebraic logic. In this paper, the first steps towards a theory of non-deterministic algebraization of logics by swap structures are given. Specifically, (...) a formal study of swap structures for LFIs is developed, by adapting concepts of universal algebra to multialgebras in a suitable way. A decomposition theorem similar to Birkhoff’s representation theorem is obtained for each class of swap structures. Moreover, when applied to the 3-valued algebraizable logics J3 and Ciore, their classes of algebraic models are retrieved, and the swap structures semantics become twist structures semantics. This fact, together with the existence of a functor from the category of Boolean algebras to the category of swap structures for each LFI, suggests that swap structures can be seen as non-deterministic twist structures. This opens new avenues for dealing with non-algebraizable logics by the more general methodology of multialgebraic semantics. (shrink)

Despite being fairly powerful, finite non-deterministic matrices are unable to characterize some logics of formal inconsistency, such as those found between mbCcl and Cila. In order to overcome this limitation, we propose here restricted non-deterministic matrices (in short, RNmatrices), which are non-deterministic algebras together with a subset of the set of valuations. This allows us to characterize not only mbCcl and Cila (which is equivalent, up to language, to da Costa's logic C_1) but the whole hierarchy of da Costa's calculi (...) C_n. This produces a novel decision procedure for these logics. Moreover, we show that the RNmatrix semantics proposed here induces naturally a labelled tableau system for each C_n, which constitutes another decision procedure for these logics. This new semantics allows us to conceive da Costa's hierarchy of C-systems as a family of (non deterministically) (n+2)-valued logics, where n is the number of "inconsistently true" truth-values and 2 is the number of "classical" or "consistent" truth-values, for every C_n.

Après avoir présenté une conception radicale des recherches participatives, ce texte montre que les savoirs produits dans un tel cadre sont de nature hybride et peuvent être qualifiés de transdisciplinaires, au sens fort de ce qualificatif qui souligne que ces savoirs vont au-delà de toute catégorisation de savoirs constitués. Cette transdisciplinarité forte pose la question de la vérité et de l’objectivité des énoncés ainsi produits. La réponse à cette double question conditionne à la fois l’excellence épistémique et la pertinence sociale (...) de ces énoncés, qui ont pour vocation de déboucher sur des actions aptes à répondre aux attentes cognitives et sociales de toutes les parties prenantes. Une telle vocation implique une conduite inédite de l’évaluation des savoirs impliqués, du point de vue de leur pertinence épistémique comme de celui de leur pertinence sociale. (shrink)

An effective method to increase the number of potential cadaveric organ donors is to make people donors by default with the option to opt out. This non-coercive public policy tool to influence people’s choices is often justified on the basis of the as-judged-by-themselves principle: people are nudged into choosing what they themselves truly want. We review three often hypothesized reasons for why defaults work and argue that the as-judged-by-themselves principle may hold only in two of these cases. We specify further (...) conditions for when the principle can hold in these cases and show that whether those conditions are met is often unclear. We recommend ways to expand nationwide surveys to identify the actual reasons for why defaults work and discuss mandated choice policy as a viable solution to many arising conundrums. (shrink)

'We desire all and only those things we conceive to be good; we avoid what we conceive to be bad.' This slogan was once the standard view of the relationship between desire or motivation and rational evaluation. Many critics have rejected this scholastic formula as either trivial or wrong. It appears to be trivial if we just define the good as 'what we want', and wrong if we consider apparent conflicts between what we seem to want and what we seem (...) to think is good. In Appearances of the Good, Sergio Tenenbaum argues that the old slogan is both significant and right, even in cases of apparent conflict between our desires and our evaluative judgements. Maintaining that the good is the formal end of practical inquiry in much the same way as truth is the formal end of theoretical inquiry, he provides a fully unified account of motivation and evaluation.

The logics of formal inconsistency (LFIs, for short) are paraconsistent logics (that is, logics containing contradictory but non-trivial theories) having a consistency connective which allows to recover the ex falso quodlibet principle in a controlled way. The aim of this paper is considering a novel semantical approach to first-order LFIs based on Tarskian structures defined over swap structures, a special class of multialgebras. The proposed semantical framework generalizes previous aproaches to quantified LFIs presented in the literature. The case of QmbC, (...) the simpler quantified LFI expanding classical logic, will be analyzed in detail. An axiomatic extension of QmbC called QLFI1o is also studied, which is equivalent to the quantified version of da Costa and D'Ottaviano 3-valued logic J3. The semantical structures for this logic turn out to be Tarkian structures based on twist structures. The expansion of QmbC and QLFI1o with a standard equality predicate is also considered. (shrink)

In 1986, Mikenberg et al. introduced the semantic notion of quasi-truth defined by means of partial structures. In such structures, the predicates are seen as triples of pairwise disjoint sets: the set of tuples which satisfies, does not satisfy and can satisfy or not the predicate, respectively. The syntactical counterpart of the logic of partial truth is a rather complicated first-order modal logic. In the present article, the notion of predicates as triples is recursively extended, in a natural way, to (...) any complex formula of the first-order object language. From this, a new definition of quasi-truth is obtained. The proof-theoretic counterpart of the new semantics is a first-order paraconsistent logic whose propositional base is a 3-valued logic belonging to hierarchy of paraconsistent logics known as Logics of Formal Inconsistency, which was proposed by Carnielli and Marcos in 2002.

In 1988, J. Ivlev proposed some (non-normal) modal systems which are semantically characterized by four-valued non-deterministic matrices in the sense of A. Avron and I. Lev. Swap structures are multialgebras (a.k.a. hyperalgebras) of a special kind, which were introduced in 2016 by W. Carnielli and M. Coniglio in order to give a non-deterministic semantical account for several paraconsistent logics known as logics of formal inconsistency, which are not algebraizable by means of the standard techniques. Each swap structure induces naturally a (...) non-deterministic matrix. The aim of this paper is to obtain a swap structures semantics for some Ivlev-like modal systems proposed in 2015 by M. Coniglio, L. Fariñas del Cerro and N. Peron. Completeness results will be stated by means of the notion of Lindenbaum–Tarski swap structures, which constitute a natural generalization to multialgebras of the concept of Lindenbaum–Tarski algebras.

Though it is held that some models in science have explanatory value, there is no conclusive agreement on what provides them with this value. One common view is that models have explanatory value vis-à-vis some target systems because they are developed using an abstraction process. Though I think this is correct, I believe it is not the whole picture. In this paper, I argue that, in addition to the well-known process of abstraction understood as an omission of features or information, (...) there is also a family of abstraction processes that involve aggregation of features or information and that these processes play an important role in endowing the models they are used to build with explanatory value. After offering a taxonomy of abstraction processes involving aggregation, I show by considering in detail several models drawn from different sciences that the abstraction processes involving aggregation that are used to build these models are responsible for their having explanatory value.

Suszko's Thesis maintains that many-valued logics do not exist at all. In order to support it, R. Suszko offered a method for providing any structural abstract logic with a complete set of bivaluations. G. Malinowski challenged Suszko's Thesis by constructing a new class of logics (called q-logics by him) for which Suszko's method fails. He argued that the key for logical two-valuedness was the "bivalent" partition of the Lindenbaum bundle associated with all structural abstract logics, while his q-logics were generated (...) by "trivalent" matrices. This paper will show that contrary to these intuitions, logical two-valuedness has more to do with the geometrical properties of the deduction relation of a logical structure than with the algebraic properties embedded on it.

The article went deeper into Richard Rorty’s texts that address the self as “a set of beliefs and desires.” In an imbrication of philosophy with psychoanalysis, Rorty’s hermeneutics accompanies the critique of psychoanalysis regarding the self-centralization from Metaphysical tradition, one of the strategies of self-redescription. The other strategy is aesthetic redescription. This redescription is based on understanding the psychic world as an encounter of “beliefs and desires” as “quasi-people.” The thread of our argument is the articulation of psychoanalysis with the (...) concept of “hegemony.” This reflexive line occurs due to the agonist and conflicting context of internal alterity from the “interpersonal” relationship between conscious and unconscious, rediscovering the self.

Trying to overcome Dugundji’s result on uncharacterisability of modal logics by finite logical matrices, Kearns and Ivlev proposed, independently, a characterisation of some modal systems by means of four-valued multivalued truth-functions , as an alternative to Kripke semantics.

We analyze the variety of A. Monteiro’s tetravalent modal algebras under the perspective of two logic systems naturally associated to it. Taking profit of the contrapositive implication introduced by A. Figallo and P. Landini, sound and complete Hilbert-style calculi for these logics are presented.

This paper argues that theEncomium of Helenmust be seen as a speech about the value and importance of wisdom in human life and not as much as one as aboutlogos. Gorgias sustains his vision based on a certain intellectualism which reduces moral faults to intellectual errors. This intellectualist program comprises a rationalization of emotions and a commitment with a certain tradition that discriminates between a minority with knowledge and a majority with only opinion. The consequence for Helen is that she (...) can be excused from her action at the expense of being reproached for her lack of wisdom and is thus relegated to the ignorant majority. Therefore, what is initially praise and an apology turns into severe blame. For this, I argue, the encomium can be qualified as an amusement (paignion). For theEncomium’s listeners the amusement becomes a challenge that demands they decipher the speech’s paradoxical character and appeal to their own wisdom to not be reproached like Helen. Thus theEncomiumcannot be seen as a treaty nor as mere joke but rather as an intellectualagônbetween the speech and the listener, which serves them “to arm the soul for contests of excellence”, as the epigram dedicated to Gorgias in Delfos says.

The aim of the paper is to analyze the expressive power of the square operator of Łukasiewicz logic: ∗x=x⊙x⁠, where ⊙ is the strong Łukasiewicz conjunction. In particular, we aim at understanding and characterizing those cases in which the square operator is enough to construct a finite MV-chain from a finite totally ordered set endowed with an involutive negation. The first of our main results shows that, indeed, the whole structure of MV-chain can be reconstructed from the involution and the (...) Łukasiewicz square operator if and only if the obtained structure has only trivial subalgebras and, equivalently, if and only if the cardinality of the starting chain is of the form n+1 where n belongs to a class of prime numbers that we fully characterize. Secondly, we axiomatize the algebraizable matrix logic whose semantics is given by the variety generated by a finite totally ordered set endowed with an involutive negation and Łukasiewicz square operator. Finally, we propose an alternative way to account for Łukasiewicz square operator on involutive Gödel chains. In this setting, we show that such an operator can be captured by a rather intuitive set of equations. (shrink)
