Num diálogo entre a Teoria Constitucional e a Filosofia Jurídica, O Ponto de Arquimedes procura levantar eternas interrogações sobre a fundamentação e a legitimação do Direito. Num tempo de consenso aparente e por vezes hipócrita em torno dos Direitos Humanos, o desafio é o de saber quais as suas raízes- a simples vontade do poder, sempre reversível, ou o Direito Natural e a própria natureza do Homem? A indagação sobre o ponto de apoio do Arquimedes jurídico, longe de ser supérflua (...) especulação, constitui, ao invés, a pedra angular de todo o edifício do Direito, o fulcro onde assenta a alavanca movente de todo o pensar e agir da juridicidade. Consagrando-se especialmente ao Direito Constitucional e à Filosofia do Direito, Paulo Ferreira da Cunha é professor universitário, agregado em Direito - Ciências Jurídicas Públicas (Univ. Minho), doutor em Direito - Ciências Jurídico-Políticas (Univ. Coimbra), e doutor em Direito - História/Filosofia do Direito (Univ. Paris II).

Repisando a trilha clássica de aproximação ao Direito, o livro repropõe o método realista para pensar o Direito. Um estar de novo do pensamento jurídico tradicional, com sua persistente atualidade, está a exigir que se retome e guarde a analogia do termo Direito e a conclusão de que, antes de mais, sendo o Direito uma coisa, a 'coisa justa', seus demais possíveis conceitos são somente analogados secundários que, por importantes se estimem, demandam sempre referência subalterna àquele prius significativo - antes (...) de tudo, o Direito é justo. Essa perspectiva realista reabre a esperança de que, mediando a experiência e a dialética, se reencontre e aprofunde uma teoria da justiça ancorada na natureza das coisas. Paulo Ferreira da Cunha e Ricardo Dip uniram aqui suas meditações acadêmicas para, comungando da doutrina jusnaturalista clássica formular um convite para que se pense realmente o Direito. (shrink)

Le droit doit certainement avoir une âme. Mais il a aussi un corps. Dans le corps du droit - souvent méprisé, souvent ignoré -, les symboles, l'iconologie, mais aussi la relation du juridique avec les arts et l'esthétique, gagnent de nos jours de plus en plus d'importance. On redécouvre une relation entre le droit et les sens : le droit qui écoute les parties, le droit dit aveugle ou le droit bandé, le droit qui sent et pressent par l'odorat, le (...) droit qui touche, et même un droit qui dé-gôute... La présente contribution pour une philosophie symbolique du droit recueille des études sur les différents aspects de ce droit sensible et sensitif. (shrink)

For centuries, natural law was the main philosophical legal paradigm. Now, it is a wonder when a court of law invokes it. Arthur Kaufmann already underlined a modern general "horror iuris naturalis". We also know, with Winfried Hassemer, that the succession of legal paradigms is a matter of fashion. But why did natural law become outdated? Are there any remnants of it still alive today? This book analyses a number of prejudices and myths that have created a general misconception of (...) natural law. As Jean-Marc Trigeaud put it: there is a natural law that positivists invented. Not the real one(s). It seeks to understand not only the usual adversaries of natural law (like legalists, positivists and historicists) but also its further enemies, the inner enemies of natural law, such as internal aporias, political and ideological manipulations, etc. The book puts forward a reasoned and balanced examination of this treasure of western political and juridical though. And, if we look at it another way, natural law is by no means a loser in our times: because it lives in modern human rights. (shrink)

Is the dream of EU endangered? This book reviews classic and modern values and virtues, and uses them in order to rethink Europe's present politics and its future. The idea of the Republic was born with the political ethics of ancient Greece. The current international crisis obliges Europe to face the mirror of truth: What has become of the European Idea and how fares the European Constitution? It has been a long road from the Greek Politeia to the present lack (...) of values and financial monomania in Europe, who seems to have lost any harmony between the spirit, the soul and the body of her Constitution: the will and values of the people (material constitution), the text of the Lisbon Treaty (formal constitution) and its current political interpretation and action (real constitution), making Europe a two-tier or three-tier club, far from the dream of the founding fathers. Without republican values and virtues, and failing to uphold the European social model, the European Union would devolve into moral, social and democratic bankruptcy. (shrink)

Otto Neurath’s empiricist methodology of economics and his contributions to politi- cal economy have gained increasing attention in recent years. We connect this research with contemporary debates regarding the epistemological status of thought experiments by reconstructing Neurath’s utopias as linchpins of thought experiments. In our three reconstructed examples of different uses of utopias/dystopias in thought experiments we employ a reformulation of Häggqvist’s model for thought experiments and we argue that: (1) Our reformulation of Häggqvist’s model more adequately complies with many (...) uses of thought experiments, especially with the open-ended discussions of utopias and dys- topias in thought experiments. (2) As a strict logical empiricist, Neurath is committed to a strictly empiricist account of thought experiments. John Norton’s empiricist argument view can indeed account for the justifications of empirical beliefs and genuine discoveries targeted by scientific utopianism in three distinct (yet connected) ways, all of which Neur- ath already contemplated: (2.I) Dealing with utopias and thought experiments on a regular basis increases creativity and inventiveness. (2.II) Particular ways of presenting knowl- edge facilitate scientific discovery and social progress. (2.III) The use of utopias in thought experiments can prompt conceptual change and allow access to new phenomena. We con- clude by highlighting that, even though thought experiments support a positive attitude for exploring new social possibilities, Neurath points out that active decisions are unavoidable. The exploration of alternatives and the awareness of a need for decisions in policy discus- sion avert a technocratic outlook in social science. (shrink)

The present paper draws a contrast between the notions of τὸ παρ’ ἡμᾶς and τὸ ἐφ’ ἡμῖν to the effect that, according to Chrysippus, each has a different role to play and different requirements to meet, the former being especially tailored to suit the exigencies of praise and blame taken as exhortations, the latter those of desert and justice in praising and blaming as well as honoring and punishing.

O uso da inteligência artificial no Poder Judiciário ainda encontra fortes limitações à luz da compreensão representacional-computacional da mente. A exemplo do projeto pioneiro do juiz robô na Estônia, a dificuldade reside na incapacidade de apreensão da narrativa subjetiva da máquina. Logo, através da experiência do ser-aí-no- mundo de Heidegger, define-se um contraste entre cognição humana e funcionamento computacional. Partindo de uma pesquisa qualitativa e de cunho bibliográfico, busca-se demonstrar a complexidade de conceber dispositivos puramente físicos com inteligências aptas a (...) substituírem juízes por robôs. Conclui-se que ainda não há tecnologia capaz de substituir a ciência cognitiva heideggeriana do Dasein. (shrink)

Resumo Este artigo apresenta um referencial pragmatista para compreender o estatuto epistêmico da valoração que é produzida na reflexão acerca das consequências sociais de propostas científicas e tecnológicas. O problema é posto, seguindo-se as considerações de Bertrand Russell sobre o impacto da ciência na sociedade. Russell argumenta que a valoração de arranjos sociais fica fora dos limites do conhecimento, porque valorações não podem ser verdadeiras ou falsas, em sentido correspondencial. Isso leva o pensamento social a um impasse, pois não se (...) pode saber que dado arranjo social seria indesejável ou inadequado. Este texto esboça uma alternativa, a partir dos trabalhos sobre valoração de Clarence Irving Lewis, tomados em continuidade com a teoria da investigação de John Dewey. Esse referencial alternativo assume noções epistêmicas de verdade e justificação, o que permite que valorações possam ser concebidas em contextos de investigação e, assim, como objetos de conhecimento.This article presents a pragmatist framework to understand the epistemic status of valuations produced upon reflection on social consequences of scientific and technological proposals. The problem is set following Bertrand Russell’s considerations on the impact of science on society. Russell argues that valuating social arrangements falls beyond the limits of knowledge, because valuations cannot be true or false in the sense of correspondence. This leads social thought to a deadlock, since one cannot know that a given social arrangement would be undesirable or inadequate. This article sketches an alternative from Clarence Irving Lewis’s works on valuation taken in continuity with John Dewey’s theory of inquiry. This alternative framework assumes epistemic notions of truth and justification, allowing that valuations can be construed in contexts of inquiry and thus as objects of knowledge. (shrink)

O desenvolvimento tecnológico promoveu o aumento de produção e compartilhamento de conteúdo em plataformas digitais, sendo difícil gerenciar o acesso adequado a informações. O presente artigo tem como objetivo discutir os efeitos do direito ao esquecimento no ambiente digital, considerando o processo de desindexação como estratégia para operacionalizar a efetividade desse direito. Tomando como referências arcabouços teóricos-conceituais acerca da complexidade compósita da informação e de antinomias entre a dignidade da pessoa humana e a liberdade de expressão e o direito à (...) informação, oriundos, respectivamente, da Ciência da Informação e do Direito, analisam-se e discutem-se algumas decisões jurisprudenciais e posicionamentos doutrinários no cenário brasileiro. O direito ao esquecimento está cercado de ambivalências e desafios de ordens normativa, tecnológica e cultural, num compartilhamento de informações em níveis sem precedentes que interferem negativamente na sua efetivação no ambiente digital.

In this article, I discuss Otto Neurath’s philosophy in the context of Vienna Circle modernism. Following recent scholarship, the discussion considers as a starting point Neurath’s participation at the fourth International Congress of Modern Architecture (CIAM IV). However, the image of Neurath’s modernism that results from this perspective is incomplete because it tends to overlook the importance of scientific utopianism in Neurath’s thought. Scientific utopianism is a methodology proposed by Neurath for the social sciences in technological contexts, in which scientists (...) elaborate and develop plans (utopias) for the transformation of society, thus contributing to an informed societal debate. Decisions are nevertheless kept outside the domain of scientific activity. I claim that recognizing the centrality of scientific utopianism in Neurath’s philosophy is fundamental to understand Neurath’s modernism. This interpretation highlights the affinities of Neurath’s philosophy of the social sciences with the modern utopianism of H. G. Wells. Both authors consider that there can be no ultimate solution to social problems but that a plural and constant debate of proposals is fundamental for the improvement of society. Therefore, Neurath’s modernism connects his philosophy of science to the literary utopian tradition. (shrink)

We present a new functional interpretation, based on a novel assignment of formulas. In contrast with Gödel’s functional “Dialectica” interpretation, the new interpretation does not care for precise witnesses of existential statements, but only for bounds for them. New principles are supported by our interpretation, including the FAN theorem, weak König’s lemma and the lesser limited principle of omniscience. Conspicuous among these principles are also refutations of some laws of classical logic. Notwithstanding, we end up discussing some applications of the (...) new interpretation to theories of classical arithmetic and analysis. (shrink)

Neurath’s scientific utopianism is the proposal that the social sciences should engage in the elaboration, development, and comparison of counterfactual scenarios, the ‘utopias’. Such scenarios can be understood as centerpieces of scientific thought experiments, that is, in exercises of imagination that not only promote conceptual revision, but also stimulate creativity to deal with experienced problems, as utopias are efforts to imagine what the future could look like. Moreover, utopian thought experiments can offer scientific knowledge to inform political debates and decisions, (...) contributing to the shaping of society. This essay reconstructs a historical event as an example of Neurath’s utopianist methodology. In the late 1970s and early 1980s, a scientific and political commission appointed by the Western German Parliament devised and compared four scenarios for future energetic-economic policies. Conclusions of the commission informed political decisions that put Western (later reunified) Germany in a route towards becoming a green industrial power. A fundamental part of the commission’s work involved an appeal to imagination, allowing for the characterization under Neurath’s methodology. (shrink)

This paper compares the claims about our knowledge of the external world presented by Rudolf Carnap, in the book known as the Aufbau, to those of Clarence Irving Lewis, in Mind and the World-Order. This comparison is made in terms of the opposition to Kantian epistemology that both books establish; the Aufbau is regarded as the peak of the logicist tradition and Mind and the World-Order is taken in continuity with pragmatism. It is found that both books present knowledge of (...) the external world as a consequence of a structural organization of human experience. However, there is an important point of divergence: the concept of verification each author adopts is different, such a concept was even a matter of discussion between Lewis and the Vienna Circle. This paper shows this disagreement but also shows how Carnap changed his point of view in the decade after the Aufbau was published, towards a standpoint which is much closer to Lewis’s ideas. In that process, nevertheless, Carnap changed his focus and did not deal with the problem of the external world anymore. This paper also seeks to draw attention to some features of the relation between Carnap and the pragmatist tradition which have only recently started to attract interest. (shrink)

O utopianismo científico de Neurath é a proposta para que as ciências sociais se envolvam na elaboração, desenvolvimento e comparação de cenários contrafactuais, as ‘utopias’. Tais cenários podem ser entendidos como peças centrais de experimentos de pensamento científicos, isto é, em exercícios da imaginação que não apenas promovem a revisão conceitual, mas também estimulam a criatividade para lidar com problemas vivenciados, já que utopias são esforços para imaginar como o futuro poderia ser. Ademais, experimentos de pensamento utópicos podem oferecer conhecimento (...) científico para informar debates e decisões políticas, contribuindo para formatar a sociedade. Este ensaio reconstrói um evento histórico como um exemplo da metodologia utopianista de Neurath. No final dos anos 1970 e início dos anos 1980, uma comissão científica e política designada pelo parlamento da Alemanha Ocidental inventou e comparou quatro cenários para políticas energético-econômicas futuras. Conclusões da comissão informaram decisões políticas que puseram a Alemanha Ocidental (e depois reunificada) em um caminho para se tornar uma potência industrial verde. Uma parte fundamental do trabalho da comissão envolveu um apelo à imaginação, permitindo a caracterização sob a metodologia de Neurath. (shrink)

Neste artigo apresentamos as propostas de Otto Neurath para o problema da unidade da ciência. Conhecido integrante do Círculo de Viena, Neurath defende que a ciência deve ser unificada por meio da chamada concepção de mundo científica, uma orientação ou atitude em relação ao mundo e aos problemas que é característica da ciência. Neste artigo apresentamos o caráter social dos projetos de Neurath, como o da Enciclopédia Internacional da Ciência Unificada. Contrastamos a proposta de Neurath com a crítica pós-modernista da (...) abordagem contextualizada dos estudos sobre a ciência. Essa crítica parte de estudos de comunidades científicas e, em geral, apresenta a conclusão de que não há um fator que unifique a ciência. O termo "ciência" denotaria apenas uma coleção de atividades sem características relevantes em comum. A comparação feita mostra que a posição de Neurath é compatível com a abordagem contextualizada, apesar de defender a unidade da ciência. Por fim, avaliamos o aspecto político da proposta de Neurath diante da crítica pós-moderna e notamos que as ideias do Círculo de Viena e da Enciclopédia podem ser valiosas nos dias de hoje. This paper discusses Otto Neurath's proposal for the problem of the unity of science. This author, a well-known member of the Vienna Circle, proposes that science is to be unified by the so-called scientific world-conception, a characteristic orientation or attitude of science towards the world and the problems it deals with. In this paper, emphasis is given to the social aspect of Neurath's projects, as found, for instance, in the International Encyclopedia of Unified Science. It contrasts Neurath's proposal with the post-modernist criticism, developed in the contextualized approach to science studies, that stems from studies of scientific communities and, in general, presents the conclusion that there is no unifying factor for science. The term 'science' would then denote just a collection of activities with no relevant common characteristics. The comparison made shows that Neurath's position is compatible with the contextualized approach, even though he defends the unity of science. Finally, the political aspect of Neurath's proposal is evaluated in the light of the post-modernist criticism, and it is pointed out that the ideas of the Vienna Circle and the Encyclopedia might be valuable nowadays.

Este artigo discute a relação entre filosofia da ciência e filosofia da educação a partir do texto de John Dewey Unity of Science as a Social Problem. Dewey propõe que o problema da unidade da ciência seja trabalhado de um ponto de vista não apenas epistemológico, mas também social. Isso é porque nosso entendimento sobre a ciência influencia a educação. A proposta de Dewey é discutida em relação às considerações de filósofos da ciência recentes, como Peter Galison e Paul Feyerabend, (...) de que a ciência não deve ser concebida como um todo unificado.

This Special Issue brings a selection of peer-reviewed papers that were presented at the 12th Principia International Symposium: Models and Modeling in the Sciences, Florianópolis, Brazil, online, August 2021. In this preface, the chair and the secretary of the organizing committee comment the symposium's context and briefly present the issue.

Otto Neurath and John Dewey share the understanding that science must have a prominent role in democratic social reform. This is a common aim that brought logical empiricism and pragmatism together in the first half of the 20th century, but there are differences between the two stances. On the one hand, Neurath sees a limitation of scientific knowledge, considering that it cannot determine decisions to be taken in the course of social reform. Such decisions, in the logical empiricist view, are (...) a matter of politics. On the other hand, Dewey sees a continuity among all forms of inquiry and, therefore, the conclusions of valuational inquiry are analogous in their epistemic claims to the conclusions in factual (natural or social inquiry). This paper investigates the divergence and concludes that pragmatist continuity of inquiry is set in a psychological context that disregards a difference in objectivity between factual and valuational inquiry.

Neurath’s approach to the problem of the unity of science is different from conceptions we may call traditional, to know, those that consider that what unites in one single concept the diverse sciences is the adoption of a method, or those that defend that this is carried through by certain characteristics which can be found in the body of knowledge considered scientific. Neurath’s stance also diverges from the standpoint that there is no unifying factor for science, that is, the view (...) that the different sciences are only classified under such concept because of the historical origin of such activities. Neurath’s proposal is to consider science as an attitude, a posture in relation to the problems of the world, the scientific world-conception. This text presents such approach in connection to the aspect of social transformation that can be found in Neurath’s thought. This is done following a comprehension of the ideas of the Vienna Circle, seeking to understand a continuity among the ideas of the members of such group, especially Neurath and Carnap. The present text aims, as well, at recovering the Neurathian idea that we can use a philosophical approach to science to struggle against the problems of the world. (shrink)
