En el mundo académico contemporáneo han venido tomando fuerza, desde hace varias décadas, los temas de la interdisciplinariedad y la transdisciplinariedad, como respuesta de un sector de la comunidad científica a los problemas de la especialización y a la desconexión entre las ciencias. Como todo elemento o aspecto de la realidad, este tema requiere de una debida fundamentación filosófica que se encuentra en el pensamiento clásico. En el presente artículo se intenta mostrar la relación entre la tradición de la filosofía (...) perenne y este fundamento, atendiendo, sobre todo, a la importancia de la mirada holística del fenómeno ético y pretendiendo sustentar que el diálogo entre las ciencias sólo es posible rescatando el paradigma metafísico, legado por los griegos a la civilización occidental y defendido por MacIntyre en su libro "Ethics in the Conflicts of Modernity. An Essay on Desire, Practical Reasoning, and Narrative" (University of Cambridge, 2016). (shrink)

Concerns about threats to human autonomy feature prominently in the field of AI ethics. One aspect of this concern relates to the use of AI systems for problematically manipulative influence. In response to this, the European Union’s draft AI Act (AIA) includes a prohibition on AI systems deploying subliminal techniques that alter people’s behavior in ways that are reasonably likely to cause harm (Article 5(1)(a)). Critics have argued that the term ‘subliminal techniques’ is too narrow to capture the target cases (...) of AI-based manipulation. We propose a definition of ‘subliminal techniques’ that (a) is grounded on a plausible interpretation of the legal text; (b) addresses all or most of the underlying ethical concerns motivating the prohibition; (c) is defensible from a scientific and philosophical perspective; and (d) does not over-reach in ways that impose excessive administrative and regulatory burdens. The definition is meant to provide guidance for design teams seeking to pursue responsible and ethically aligned AI innovation. (shrink)

In this paper two systems of AGM-like Paraconsistent Belief Revision are overviewed, both defined over Logics of Formal Inconsistency (LFIs) due to the possibility of defining a formal consistency operator within these logics. The AGM° system is strongly based on this operator and internalize the notion of formal consistency in the explicit constructions and postulates. Alternatively, the AGMp system uses the AGM-compliance of LFIs and thus assumes a wider notion of paraconsistency - not necessarily related to the notion of formal (...) consistency. (shrink)

This paper briefly outlines some advancements in paraconsistent logics for modelling knowledge representation and reasoning. Emphasis is given on the so-called Logics of Formal Inconsistency (LFIs), a class of paraconsistent logics that formally internalize the very concept(s) of consistency and inconsistency. A couple of specialized systems based on the LFIs will be reviewed, including belief revision and probabilistic reasoning. Potential applications of those systems in the AI area of KRR are tackled by illustrating some examples that emphasizes the importance of (...) a fine-tuned treatment of consistency in modelling reputation systems, preferences, argumentation, and evidence.

In the whole Corpus Platonicum, we find in principle only one "direct argument" (Charles Kahn) for the existence of the ideas (Tim.51d3-51e6). The purpose of the article is to analyse this argument and to answer the question of why Plato in the Timaeus again defended the existence of the ideas despite the objections in the Parmenides. He defended it again because the latent presupposition of the apories in the Parmenides, the substantial view of sensibles, is removed through the introduction of (...) space as "substantialized extension". First (I) it is shown that Plato remained in dialogues, like the Sophist and Politicus, faithful to the "theory of ideas" despite his criticism in the Parmenides. The common theme in the trilogy of the Theaetetus, Sophist and Politicus is to refute relativism by showing that any relativism presupposes something absolute that is something like the "theory of ideas". The second part of the paper (II) examines closely the logical structure of the argument for the existence of ideas in the Timaeus (51d3-52a7). The third part (III) shows how this argument can avoid the criticism of ideas in the Parmenides. In the Parmenides, sensibles are treated as substantial entities. But, as the Timaeus shows, sensibles are not substantial entities but merely qualities, namely qualities of space, which is the only substance in the sensible world. A shortened English version of the paper appeared in Proceedings of the Fourth Symposium Platonicum, Granada, Selected papers, ed. by T. Calvo/L. Brisson, Academia Verlag, St. Augustin, 1997, 179-186. -/- But the only "direct argument" (Tim.51d3-51e6) seems to be interestingly flawed. Cf. Ferber, Rafael; Hiltbrunner, Thomas, (2005). (shrink)

Autonomy has been central to moral and political philosophy for millenia, and has been positioned as a critical aspect of both justice and wellbeing. Research in psychology supports this position, providing empirical evidence that autonomy is critical to motivation, personal growth and psychological wellness. Responsible AI will require an understanding of, and ability to effectively design for, human autonomy (rather than just machine autonomy) if it is to genuinely benefit humanity. Yet the effects on human autonomy of digital experiences are (...) neither straightforward nor consistent, and are complicated by commercial interests and tensions around compulsive overuse. This multi-layered reality requires an analysis that is itself multidimensional and that takes into account human experience at various levels of resolution. We borrow from HCI and psychological research to apply a model (“METUX”) that identifies six distinct spheres of technology experience. We demonstrate the value of the model for understanding human autonomy in a technology ethics context at multiple levels by applying it to the real-world case study of an AI-enhanced video recommender system. In the process we argue for the following three claims: 1) There are autonomy-related consequences to algorithms representing the interests of third parties, and they are not impartial and rational extensions of the self, as is often perceived; 2) Designing for autonomy is an ethical imperative critical to the future design of responsible AI; and 3) Autonomy-support must be analysed from at least six spheres of experience in order to approriately capture contradictory and downstream effects.

The paper proposes (1.) a non-standard interpretation of the proverbial expression “deuteros plous” by giving a fresh look to Phaedo, 99c9-d1. Then (2.) it proceeds to the philosophical problem raised in this passage according to this interpretation, that is, the problem of the “hypothesis” or the “unproved principle”. It indicates finally (3.) the kernel of truth contained in the standard Interpretation and it concludes with some remarks on the “weakness of the logoi”.

Este artigo investiga alguns usos da metáfora da linguagem como cálculo em Wittgenstein. A metáfora do cálculo emerge, nos anos 30, numa interlocução com o referencialista, e é ali instrumental na recondução do olhar filosófico para os usos efetivos do simbolismo linguístico. Contudo, foi levada longe demais, ao sugerir uma imagem da linguagem composta apenas de inferências à maneira dos sistemas de regras fechados. Isto embargaria certa expansão pragmática do contexto criterial da análise conceitual. Mas a aplicabilidade do símile do (...) cálculo não é invalidada. A metáfora será reativada em manuscritos posteriores, sempre e quando puder servir aos mesmos propósitos do período intermediário, à medida que o ambiente dialógico convoque novas vozes dogmaticamente referencialistas. Ainda assim, é nos manuscritos intermediários que melhor se esclarece o seu funcionamento. Tal movimento exemplifica, por fim, um método filosófico que não procede por meio da superação de problemas à maneira científica. (shrink)

La finalidad del presente artículo es descubrir la presencia del concepto de persona en la doctrina de la soberanía de Carl Schmitt. A pesar de que este concepto tuvo un amplio desarrollo metafísico en el seno del pensamiento cristiano durante la antigüedad tardía, jamás pudo desembarazarse de la impronta jurídica de sus creadores los juristas romanos. Por tal razón, sirvió como soporte conceptual para el posterior despliegue de la noción de persona jurídica, sistematizada a lo largo de la modernidad. Para (...) lograr nuestro objetivo, intentaremos rastrear la transformación del concepto de persona a lo largo de la edad media y la modernidad, así como revisar el concepto de soberanía en la teoría política moderna. Por otro lado, estudiaremos la noción de decisión en la obra de Carl Schmitt, noción que el gran jurista alemán utilizó para definir su propia concepción de la soberanía. A partir de estas precisiones, intentaremos establecer la relación existente entre la noción de persona y la de decisión en el seno de la concepción schmittiana de la soberanía tomando como hilo conductor los presupuestos teológicos implícitos en ella. Como veremos, tales presupuestos nos remitirán a la obra del pensador danés Søren Kierkegaard, cuyas doctrinas nos mostrarán todo el alcance del planteamiento schmittiano. De esta manera, podemos concluir que el concepto de persona subyacente al decisionismo schmittiano ha sido transformado, en primer término, en el de existencia política, noción determinada por la relación de enemistad; y, en segundo lugar, en el de unidad de la personalidad, concepto determinado por la actualización de la dimensión espiritual al interior de la condición humana.

A strange dialectical reversal characterizes the oppositions which psychoanalysis posits against philosophy and neuroscience: what psychoanalysis intervenes with as a unique and missing quality of these subjects, reveals itself upon enquiry as already having been a feature of said subjects. This article first discusses the failed intervention of psychoanalysis within the perceived totalities and absolutes of German idealism. Psychoanalysis, founded on an ontological division and internal inconsistency with a retroactive logic, finds this internal contradiction already reflected within the supposed totalities (...) of Schelling and Hegel. Schelling’s “blind act,” a decision with no prior foundation that grounds an abstract identity-in-itself, appears as the counterpart to what Badiou calls the strictly “analytic act.” Hegel’s Science of Logic, in which the inconclusive interpenetration of being and nothing presupposes its own conclusion in the transitions to essence, and in which an internal incompleteness and contradiction are retroactively constitutive of the concept, similarly nullifies the intervention of psychoanalysis. Finally, precisely such a reversal is presented in neuroscience, where the constitutive contradiction of contingently functional neuronal formations in the adaptive “multiple demand” model of executive functioning repeats the contingent and self-contradicting psychoanalytic subject as being its own deference within linguistic, discursive formations.

“Trends in Logic XVI: Consistency, Contradiction, Paraconsistency, and Reasoning - 40 years of CLE” is being organized by the Centre for Logic, Epistemology and the History of Science at the State University of Campinas (CLEUnicamp) from September 12th to 15th, 2016, with the auspices of the Brazilian Logic Society, Studia Logica and the Polish Academy of Sciences. The conference is intended to celebrate the 40th anniversary of CLE, and is centered around the areas of logic, epistemology, philosophy and history of (...) science, while bringing together scholars in the fields of philosophy, logic, mathematics, computer science and other disciplines who have contributed significantly to what Studia Logica is today and to what CLE has achieved in its four decades of existence. It intends to celebrate CLE’s strong influence in Brazil and Latin America and the tradition of investigating formal methods inspired by, and devoted to, philosophical views, as well as philosophical problems approached by means of formal methods. The title of the event commemorates one of the three main areas of CLE, what has been called the “Brazilian school of paraconsistency”, combining such a pluralist view about logic and reasoning.

This article considers the historical tension in conceptualising Marx's materialism (dialectical and historical) as either a break from, or a fidelity to, Hegelian dialectics, and the methods by which this tension is itself subsumed under an insistence on vindicating the radical irreducibility of Marxist thought. Ultimately, however, it is argued that the question of whether Marx should or should not be framed alongside Hegel is the wrong question. It is not a question of 'Marx by himself' or 'Marx and... [Hegel]', (...) but rather of 'Marx without himself': as with any radical event in the history of ideas, it is a benefit to Marx's innovativeness that he can be retrospectively articulated according to historical traditions whilst simultaneously breaking from them. -/- .

Quantum mechanics is a fundamental theory in physics that describes the behavior of subatomic particles and systems at very small scales. Unlike classical theories, quantum mechanics introduces elements of indeterminism in the description of physical phenomena. There are fundamental limits to the precision with which certain physical properties, such as the position and momentum of a particle, can be measured simultaneously. This implies that, even if all the initial conditions of a quantum system are known, its future behavior cannot be (...) predicted with absolute certainty. -/- This quantum indeterminacy raises philosophical questions about determinism and free will, as well as their relationship to morality. Determinism holds that all actions and events are predetermined by prior causes, which challenges the traditional notion of moral responsibility based on control and predictability. In contrast, indeterminism posits that there are elements of randomness and variability in the workings of the universe. -/- From a moral and philosophical point of view, the presence of indeterminism in quantum mechanics poses challenges to the attribution of moral responsibility. If our actions are influenced by random events, how can we be morally responsible for them? (shrink)

Two systems of belief change based on paraconsistent logics are introduced in this article by means of AGM-like postulates. The first one, AGMp, is defined over any paraconsistent logic which extends classical logic such that the law of excluded middle holds w.r.t. the paraconsistent negation. The second one, AGMo , is specifically designed for paraconsistent logics known as Logics of Formal Inconsistency (LFIs), which have a formal consistency operator that allows to recover all the classical inferences. Besides the three usual (...) operations over belief sets, namely expansion, contraction and revision (which is obtained from contraction by the Levi identity), the underlying paraconsistent logic allows us to define additional operations involving (non-explosive) contradictions. Thus, it is defined external revision (which is obtained from contraction by the reverse Levi identity), consolidation and semi-revision, all of them over belief sets. It is worth noting that the latter operations, introduced by S. Hansson, involve the temporary acceptance of contradictory beliefs, and so they were originally defined only for belief bases. Unlike to previous proposals in the literature, only defined for specific paraconsistent logics, the present approach can be applied to a general class of paraconsistent logics which are supraclassical, thus preserving the spirit of AGM. Moreover, representation theorems w.r.t. constructions based on selection functions are obtained for all the operations. (shrink)

"Paraconsistent Belief Revision Based on a Formal Consistency Operator" delves into Belief Revision—a significant area of research in Formal Philosophy that uses logic to model the ways in which human and artificial agents modify their beliefs in response to new information and examines how these changes can be considered rational. -/- Originally authored as a PhD thesis (previously published in Portuguese), this work provides a novel epistemic interpretation of Paraconsistency through Paraconsistent Belief Revision systems. It explores the concept of paraconsistency (...) from the standpoint of epistemic attitudes of acceptance and rejection. -/- This work challenges the traditional notion that accepting a new belief requires retracting its negation from the current epistemic state. The author contends that such reflexive retraction goes against the principle of informational economy, which is a crucial aspect of rationality in the context of belief change. Consequently, the phenomenon of paraconsistency is further examined from this fresh perspective of belief change, shedding light on the complexities of the Logics of Formal Inconsistency (LFIs). These LFIs provide the foundational logic, offering a comprehensive framework for understanding and implementing paraconsistent principles within belief revision systems. -/- This thesis was supervised by Marcelo Esteban Coniglio and co-supervised by Márcio Moretto Ribeiro, as part of Rafael Rodrigues Testa's doctoral studies at the University of Campinas (Unicamp), Brazil.

La questione sulla verità del cristianesimo è fondamentale e ineludibile. In essa si trova uno dei filoni fondamentali del pensiero di Joseph Ratzinger – Benedetto XVI. In fondo si trovano coinvolti una serie di argomenti che si possono riassumere nel rapporto tra fede e ragione, tra il Dio della fede e il Dio dei filosofi. Nella visione cristiana ambedue non si contrappongono, ma s’incontrano. La “distinzione mosaica” s’incontra con la “distinzione socratica” . La pretesa di verità del cristianesimo conduce a (...) delle conseguenze sia nell’ambito della religione, sia in quello della filosofia e della morale.

This paper deals with the deuteros plous, literally ‘the second voyage’, proverbially ‘the next best way’, discussed in Plato’s Phaedo, the key passage being Phd. 99e4-100a3. I argue that (a) the ‘flight into the logoi’ can have two different interpretations, a standard one and a non-standard one. The issue is whether at 99e-100a Socrates means that both the student of erga and the student of logoi consider images (‘the standard interpretation’), or the student of logoi does not consider images but (...) that “consistency should suffice for truth” (‘the non-standard interpretation’); (b) the non-standard one implies the problem of the hypothesis, a problem analogous to the problem of the elenchus; (c) there is a structural analogy between Descartes’ ontological argument for the existence of God in his 5th Meditation and the final proof for the immortality of the soul in the Phaedo.

The debate over Plato’s “ so called unwritten doctrines”, which he communicated only to a small circle of trusted disciples, has caused a stir among philosophers in recent decades. Rafael Ferber assumes a differentiated position in this controversy. He is convinced that the unwritten doctrines did exist, but that Plato, for reasons inherent in the process of gaining knowledge, was unable to communicate these doctrines even to his closest disciples. In this book, Ferber outlines the discussion and summarizes the (...) standpoints of greatest interest. Ever since Aristotle, we have known that Plato did not put his most important teachings into writing, but instead communicated them only orally to the inner circle of his disciples. While the extant dialogues merely pass down Plato’s “exoteric” doctrines, his most important “esoteric” insights were not meant for the general public. In the meantime, the contents and the significance of Plato’s “unwritten doctrines” have become the subject of debate in philosophical circles. Fifteen years ago, at the height of the controversy over the “unwritten doctrines”, Rafael Ferber entered the fray with a small book. He proposed that Plato was also unable to communicate the “unwritten doctrines” because the highest principles (i.e. the subject of the unwritten doctrines) cannot be known through logical operations due to an epistemological paradox. Ferber’s differentiated position met with great respect and acceptance, although in individual cases it was also rejected. Ferber’s new book again presents the text of 1991, but significantly expands on it through new perspectives and an outline of the discussion it triggered. In this book, the reader learns what is meant by Plato’s unwritten doctrines and what the controversy is all about. (shrink)

This article asks the question “Why did Plato not write the ‘unwritten doctrine’?” and answers it by citing a combination of two obstacles. The first derives from the limitations of the episteme available to an embodied soul about the essence of the good. Even if the dialectician has access to some kind of knowledge, the mismatch between the unchanging essence of the good and the precarious logoi which aim to identify it (and allow others some measure of access to it) (...) can never fully be overcome. At best, Socrates (or Plato) can lead souls to an incomplete account of it: It is possible that even the most expert dialectician can only have a claim to knowledge, but no absolute certainty. Another obstacle lies in the audience or readership itself: No shortcut to understanding is possible, and yet a mere written presentation, which is all they have, is just such a shortcut, and so represents an empty promise. In memory of Charles H. Kahn (1928–2023), a letter of his from September 5, 1989, concerning the question “Why did Plato not write the ‘unwritten doctrine’?” is published, along with some comments.

The article tries to prove that the famous formula "epekeina tês ousias" has to be understood in the sense of being beyond being and not only in the sense of being beyond essence. We make hereby three points: first, since pure textual exegesis of 509b8–10 seems to lead to endless controversy, a formal proof for the metaontological interpretation could be helpful to settle the issue; we try to give such a proof. Second, we offer a corollary of the formal proof, (...) showing that not only self-predication of the form of the Good, but of any form is not possible, that is: no form of F has the form of F. Third, we apply Spinoza’s distinction between an ens imaginarium and a chimaera to Plato’s Idea of the Good. (shrink)

*Winner of the American Philosophical Association's 2020 Essay Prize in Latin American Thought* This essay offers a novel account of the secularity of Latin American liberation philosophy. It challenges the accepted notion that liberation philosophy applies the methods and approaches of Latin American liberation theology to the philosophical arena, thus putting liberation theology on secular grounds. While this formulation is true insofar as liberation philosophy is not bound by the hermeneutics of any particular religious tradition, this formulation could be misconstrued (...) given that liberation philosophy does not premise such secularization in an undialectical understanding of secularity as secularism that disavows religion. Rather, liberation philosophy’s secularity is dialectical in that it requires constant engagement with re-ligion, not in the hermeneutics of any specific tradition but with “the traditional question of the Absolute.” Due to this often-misunderstood element of liberation philosophy, it has frequently been “ghettoized and relegated to the ‘safe’ area of theological studies,” as Eduardo Mendieta argues. However, I contend that liberation philosophy’s secular grounds offer an original contribution to philosophy as a decolonial and postsecularist liberation philosophy, one that conceives of secularism as an aspect of coloniality to be overcome, an obstacle rather than a benefit for Latin American philosophers seeking to gain a better understanding of our historical conditions.

O presente artigo apresenta um retrospecto teórico das temáticas da Cultura e Identidade – essa tomada também como identificação e individualização – dentro das principais obras de Herbert Marcuse, em especial Razão e Revolução e A Ideologia da Sociedade Industrial. Após traçar esse arcabouço, pretendemos ilustrar os conceitos filosóficos utilizando exemplos midiáticos presentes nas práticas midiáticas atuais, buscando demonstrar a pregnância que um pensamento da época da contracultura pode ter no século XXI.

This essay wants to rescue the concept of phaneroscopy, created by Charles Sanders Peirce, to adapt it in a phenomenological condition of multiple realities. Therefore, in addition to review the reflection of Peirce, we visited the approach of phenomenology of multiple realities proposed by Alfred Schutz in his reading of William James. The idea is to seek a phenomenology that goes beyond the human consciousness to other research subjects.

The article first gives an exegesis of the famous passage in the "Republic", 505d11-506a2. Attention is drawn to the fact that the principle that every soul does everything for the Good can be translated in two ways: Every soul does everything for the sake of the Good, or goes to all lengths for the sake of the Good. Depending on the different translations, we have a different picture of the platonic Socrates in the Republic, an intellectualistic Socrates for whom irrational (...) desires do not exist, or a Socrates who also accepts irrational desires. The article favours the first one. Then it attempts to show that we can elucidate some dark points in the Socratic thesis that the Good is what every soul pursues and for which every soul does everything, with the help of Aquinas’s distinction between it actio hominis and actio humana. Finally, the article outlines three substantive answers to the question “What is the Good?” – the henological, the perfectionist and the structuralist. Instead of advancing a new answer, the article suggests an uncontroversial formal starting point for an answer to this question. (shrink)

Despite the fact that Aristotle and Frege/Russell differ in how to understand the ambiguity in the meaning of the word "is", their theories share a common feature: "is" does not have a normative meaning, but a constative meaning. This paper, however, shows (1) that there is a normative meaning of "is" (and correspondingly a constative meaning of the word "ought") and (2) that the ambiguity of "is" is itself ambiguous. Furthermore, the paper proposes (3) a performative criterion for making a (...) distinction between constative and normative "is". Thereby, it is possible to attack Searle's famous argument against Hume's law. (shrink)

The paper deals with the "deuteros plous", literally ‘the second voyage’, proverbially ‘the next best way’, discussed in Plato’s "Phaedo", the key passage being Phd. 99e4–100a3. The second voyage refers to what Plato’s Socrates calls his “flight into the logoi”. Elaborating on the subject, the author first (I) provides a non-standard interpretation of the passage in question, and then (II) outlines the philosophical problem that it seems to imply, and, finally, (III) tries to apply this philosophical problem to the "ultimate (...) final proof" of immortality and to draw an analogy with the ontological argument for the existence of God, as proposed by Descartes in his 5th "Meditation". The main points are as follows: (a) the “flight into the logoi” can have two different interpretations, a common one and an astonishing one, and (b) there is a structural analogy between Descartes’s ontological argument for the existence of God in his 5th "Meditation" and the "ultimate final proof" for the immortality of the soul in the "Phaedo".

In his Vermischte Bemerkungen 43, Wittgenstein notices that he was also influenced by Oswald Spengler. The paper deals with the question of in which way Spengler influenced Wittgenstein’s late works and if it really was influence or only a coincidence of ideas. It is put forward that Spengler’s rather unknown philosophy of language influenced Wittgenstein’s philosophy of language, especially the concepts of family resemblance, antiessentialism, and language-game (Sprachspiel). A picture of the famous Neapolitan gesture of “negation” which motivated Wittgenstein to (...) give up the picture theory of language is also shown with an example taken from Andrea de Jorio, La mimica degli antichi investigala nel gestire napoletano, Napoli 1832.

A mudança da concepção do critério geral da significação que tinha Wittgenstein no seu período intermediário para a concepção dos critérios de significação do seu período posterior justifica que se fale numa correlativa mudança na aplicabilidade do conceito de ‘uso’.

The anthropologist James Frazer investigates the ritual gesture in search of be- liefs about the physical world by the native. Wittgenstein considers this a case of aspect- blindness, one that is disruptive of the conditions for understanding the native’s most triv- ial gestures. Unable to cast his glance from within the native situation, this methodological view from nowhere has an arresting effect on experience – in particular, the experience of speaking. This interruption is to be examined by means of a (...) thought experiment. Then, through the interplay of the concepts of Spirit and Aspect, a philosophical tool is described to assess the problem that can also serve as practical guide back to ordinary experience. The next step is to examine this way out in a particularly sensitive kind of experience of meaning: the aesthetic experience, also seen as a ritual. We conclude by alluding to a pos- sibly mutual illumination between aesthetic experience, translation studies and a Cavellian take on ordinary language. (shrink)

This paper aims to evidence the meaning of “ontology of present”, a concept elaborated by Michel Foucault, and intends to elucidate the philosopher’s idea that subjectivity is historically formed. The context of the concept’s emergence will be analyzed, considering Foucault’s studies on the ancient greco-roman moral, in which he discuss the role of liberty and autonomy in the development of citizens. To the philosopher, the ontology of present consists in a critic of the domination and subjugation mechanisms, produced by disciplinary (...) and control societies. With this critic, Foucault pictures theoric tools to analyze the actuality, making possible to transform the historical processes of subjectification. Keywords: ontology of the present; subjectivity; history; Michel Foucault; actuality. (shrink)

No audiovisual, a violência normalmente é vista como apenas uma ação, um sensacionalismo, especialmente as cenas de luta.

The article examines the Socratic principle that (1) virtue is knowledge and its corollary that (2) nobody errs voluntarily (nemo sua sponte peccat). It tries to show (I) that both principles are paradoxa, i.e. from a phenomenological point of view, they seem to be false; (II) that nevertheless the platonic Socrates accepts both principles as true; and finally (III) that these principles are analytical truths a priori which can only be understood if a person (soul) finds them in him- or (...) herself.

Conceptual analysis is one of the notions undergoing dramatic changes during Wittgenstein's intermediate period. There's an aspect of such changes which might prove characteristic of the new directions taken by Wittgenstein's thought after 1929: it is the notion of complete analysis. We believe that Wittgenstein's treatment of this notion is also an interesting indication of new concerns generated by the "new method" itself, in terms of its radical openness to dialogism and its anti-dogmatism. Our aim here will be to explore (...) a couple of hints as to why this can be so. (shrink)

A similar framing of inarticulable formations, of pure multiplicities, marks the respective projects of Deleuze and Laplanche. The absolute exteriority of a disjunctive multiplicity is re-inscribed as a relativised, interiorised trace. This trace-logic of Deleuze and Laplanche has definitive implications where the psychoanalytic subject and the unconscious is concerned. However, there is a difficulty in this logic of accounting for the unconscious formations enumerated by Freud (slips of the tongue, jokes, symptoms etc.). In turning to Lacan, however, the positions of (...) Deleuze and Laplanche can be illuminated (despite their attempt to ‘move beyond’ him). We see the trace in its material, unconscious substantiality upheld by the function of the big Other as an absent centre to which discourse is referred and through which the speaking subject is revealed as being in a discrepant relation to itself. The big Other, in his function as intimate, yet lacking, alterity, seems to help to resolve the problematic of multiplicity for Deleuze and Laplanche. (shrink)

O propósito deste trabalho é analisar a estrutura e discutir a aplicação da(s) lógica(s) deôntica(s) na representação de normas jurídicas. Após uma apresentação desta(s) lógic(s) e, em particular, do sistema de von Wright e da SDL (Standard Deontic Logic), veremos as dificuldades de se aplicar uma lógica à análise do direito positivo: as regras da lógica devem permitir realizar sobre as normas formalizadas somente os tipos de inferência e operaçôes lógicas intuitivamente feitas pelos juristas, ou seja, a reconstrução lógica do (...) direito positivo não se trata de uma tarefa de criação do direito, mas uma tarefa de representação daquilo que o conceito de direito usual reconhece como tal.

A Revisão de Crenças estuda como agentes racionais mudam suas crenças ao receberem novas informações. O sistema AGM, trabalho mais influente desta área apresentado por Alchourrón, Gärdenfos e Makinson, postula critérios de racionalidade para os diferentes tipos de mudança de crenças e oferece construções explícitas para tais - a equivalência entre os postulados e operações é chamado de teroema da representação. Trabalhos recentes mostram como o paradigma AGM pode ser compatível com diferentes lógicas não-clássicas, o que é chamado de AGM-compatibilidade (...) - este é o caso da família de lógicas paraconsistentes que analisamos, as Lógicas da Inconsistência Formal (LFIs, da sigla em inglês). A despeito da AGM-compatibilidade, ao se partir de uma nova lógica sua racionalidade subjacente deve ser entendida e sua linguagem deve ser efetivamente usada. Propomos assim novas construções que de fato capturam a intuição presente na LFIs - é o que chamamos de sistema AGMo. Com isso, possibilitamos a estas lógicas uma nova interpretação, na esteira da epistemologia formal. Em uma abordagem alternativa, ao se partir da AGM-compatibilidade os resultados AGM podem ser diretamente aplicados às LFIs - o que chamamos de sistema AGMp. Em ambas abordagens, provamos os respectivos teoremas da representação sempre que necessário. (shrink)

The first part of the paper (p. 10-21) tries to answer the first question of the title and describes a set of seven “knowledge-claims” made by Socrates: 1. There is a distinction between right opinion and knowledge. 2. Virtue is knowledge. 3. Nobody willingly does wrong. 4. To do injustice is the greatest evil for the wrongdoer himself. 5. An even greater evil is if the wrongdoer is not punished. 6. The just person is happy; the unjust person is unhappy. (...) 7. The pleasant is not the good. These claims seem to be the “few” (oliga) (Men. 98 b3) but “very important” (kallista) (Grg. 472 c8) things that Socrates claims to know. The second part (p. 22-39) tries to answer the second question and defends the thesis that the supposed “knowledge” of Socrates is dianoetic, but not noetic. The main new idea of this paperis the comparison of the Socratic knowledge-claims with the upper states of the mind symbolized in theDivided Line, noesis and dianoia (cf. R. 511 d7-e1). Posted.

The French theorist A. J. Greimas, inspired by such studies, is considered one of the founders of Narratology through the construction of models of analysis where these invariables would be centered in the subject of the narrative and based on the action and the transformation of them. The objective of the present essay is to analyze the ideas of Greimas, as well as to look for the logical mechanism that resides in each model.

This paper intends to show that Friedrich Nietzsche’s approach to morality or ‘immorality’ involves an attempt to see moral beliefs as a product of human psychology, rather than as a set of metaphysical ‘truths’ that are somehow given to, or discoverable by, us. Nietzsche wants to replace the metaphysical (or supernatural) account of morality with a natural one, and his treatment of moral belief-systems, from the perspective of this concern, can be divided into (a) a psychological analysis of the true (...) nature of moral action and agency, and (b) an historical/genealogical tracing of the real origins of moral values. In this paper I am going to focus on the second dimension of Nietzsche’s analysis through references from his polemical texts Beyond Good and Evil, Genealogy of Morals, Gay Science, and Will to Power. I will outline Nietzsche’s historical leitmotif on the morality of ressentiment or slave morality and will show how it figures as a point of departure for his revolutionary transvaluation of values, one that places a new order of morality which is disparagingly called ‘immoralism.’ Next, I will discuss Nietzsche’s treatment of bad conscience and posit that it involves two different stages: one is the present stage of the bad conscience as a feeling of guilt, and the other is an earlier stage. I shall argue that in order for this earlier stage to develop into the level of guilt, he needs another element, namely an indebtedness towards gods, which finds its most striking culmination in the Christian heritage of religious dogmatism. Finally, I will discuss how for Nietzsche Christianity as an ascetic ideal has promoted to preserve a declining life, i.e. a slave morality, for all of humanity. (shrink)

O presente artigo busca analisar, no aspecto da imagem audiovisual e focando na questão do movimento, a série televisiva de desenho animado Speed Racer ( Mach Go Go Go , 1967-68). Utilizando a teorização de Gilles Deleuze acerca da imagem-movimento e seus aspectos semióticos, o objetivo aqui é ver como um desenho animado, utilizando a chamada animação limitada, consegue representar o movimento automobilístico sem precisar mobilizar inúmeros elementos de animação ou mesmo rotoscopiar imagens de corridas de carros. Por fim, o (...) artigo traz algumas considerações sobre como Speed Racer , utilizando sua abordagem semiótica de movimento, agiu na linguagem do dispositivo do desenho animado, ou seja, nos campos de ação social mimetizados por qualquer realização audiovisual.

This is a short overview of Plato’s “greatest thing to be learned” or the “greatest lesson” (megiston mathêma) – the Idea of the Good.

This article is an effort to understand how the Peirce's Arrow (Logical NOR), as a logical operation, can act within the concept of Ludwig Wittgenstein's language-game, considering that the language game is a satzsystem, i.e., a system of propositions. To accomplish this task, we will cover four steps: (1) understand the possible relationship of the thought of C. S. Peirce with the founding trio of analytic philosophy, namely Frege-RussellWittgenstein, looking for similarities between the logic of Peirce and his students (notably (...) Christine Ladd and O.H. Mitchell) with a New Wittgenstein’s approach, which sees Early Wittgenstein (Tractatus Logico-Philosophicus),Middle Wittgenstein and Last Wittgenstein (Philosophical Investigations) while a coherent way of thinking and not a theoretical break; (2) describe the operation of the Peirce’s Arrow (Logical NOR) as a logical connective; (3)understand the notion of satzsystem (Middle Wittgenstein) and the possibility of applying the concept of language-game (Last Wittgenstein) on it; and (4) understand how the Logical NOR can operate within a satzsystem. The goal here is a search for the logic of the language-game and how the logical ideas of C. S. Peirce can help in this construction. And this construction might be interesting for a better understanding of the analytic philosophy of language. (shrink)

This article proposes a general strategy to overcome normative conflicts, namely, paradoxes represented in Standard Deontic Logic. This solution is based on preference relations between norms that circumvent situations of conflict. Pragmatic justifications of the proposed method are also given.

The first chapter, "Der Hintergrund von Gadamers 'Phänomenologischen Interpretationen' in Sein und Zeit" traces the origins of Gadamer’s interpretation of the Philebus in Sein und Zeit. Especially important is that Dasein is, thanks to speech , already outside of itself in the world. The second chapter "Gadamers Dialektische Ethik" gives a short summary of the main points of Gadamer's interpretation of the Philebus. The third chapter "Davidsons reinterpretation of von Gadamer's Dialektischer Ethik" 222-231), points especially to the fact that Davidson (...) sees the "Socrates post Vlastos" in the interpretation of Gadamer at work: Because every man is already in possession of some basic truths, coherence is enough to lead to substantive truths. Davidson concludes that only in “interpersonal communication” "can be thought, a grasping of the fact of an objective, that is, a shared world". Thus, Davidson sees in Gadamer's interpretation of the Philebus his own theory of triangulation anticipated. (shrink)

The paper gives (I) a short introduction to Aristotle’s theory of the soul in distinction to Plato’s and tries again (II) to answer the question of whether the individual or the general active mind of human beings is immortal by interpreting “When separated (χωρισθεìς)” (de An. III, 5, 430a22) as the decisive argument for the latter view. This strategy of limiting the question has the advantage of avoiding the probably undecidable question of whether this active νοῦς is human or divine. (...) The paper closes with an outlook (III) on the Christian belief in the resurrection of body and soul in a spiritual body (σῶμα πνευματικóν) (1 Corinthians: 15, 44) by accentuating the ethical aspect of the belief in individual immortality as a “need of reason” (Vernunftbedürfnis) (Kant, Critique of Practical Reason, A 256–258).

The article is the revised version of an inaugural lecture given at the University of Lucerne on 8 November 2001. In part (I), I give an interpretation of the first sentence of the Aristotelian Metaphysics: ‘All men desire by nature to know’. In part (II), I show how, for Aristotle, this desire to know constitutes a continuum from knowledge given by sense perception to knowledge of the first principles. In part (III), I compare this Aristotelian conception to Plato’s more ‘existentialist’ (...) approach which implies the turning of a ‘whole soul’ rather than a continuum. Preferring the latter concep- tion, I conclude with some hints of what I plan to do in the next years and give a short overview of the history of universities in Europe and Switzerland, ending with the University of Lucerne.

The article again treats the question of whether ≪the Idea of the Good is a Reality in the Universe, or beyond it. Is it immanent or transcendent?≫. Plato scholars such as Matthias Baltes and Luc Brisson have defended the thesis that Plato’s Idea of the Good is, on the one hand, beyond being in dignity and power, but, on the other, is nevertheless not transcendent over being. The article delivers first the most important arguments for the thesis of Baltes and (...) Brisson. Then, it gives two counterarguments against the thesis. Third, it concludes with some general questions concerning the deflationist interpretation of Plato’s Republic 509b9‑10, and defends again the transcendence of the Idea of the Good. (shrink)
