Wellman identified three types of conductive arguments, the third of which contains both pro and counter-considerations in the same piece of reasoning. This paper provides a pragma-dialectical analysis of this type of argumentation, with special focus on argumentation reconstruction. It argues that the account of pro/con argumentation in the framework of argument-as-product has problems solvable by a pragma-dialectical approach. The paper asserts that pro/con argumentation should be analyzed as a dialectical strategy of a protagonist, where acknowledgement of counter-considerations shows that (...) the antagonist’s reasons have been taken into consideration, although the pro-considerations override them. Thus, the pro-considerations of pro/con argumentation should be interpreted as the protagonist’s overriding defeaters of the antagonist’s counter-arguments, the protagonist incorporating the latter as counter-considerations. The paper further argues that the pragma-dialectical framework needs an additional conceptual tool to properly reconstruct complex forms of pro/con argumentation. Finally, the pragma-dialectical approach to reconstruct pro/con argumentation has several advantages, especially to a more logical-structural approach to complex pro/con argumentation. (shrink)

This volume features original essays on the philosophy of love. The essays are organized thematically around the past, present, and future of philosophical thinking about love. In section I, the contributors explore what we can learn from the history of philosophical thinking about love. The chapters cover Ancient Greek thinkers, namely Plato and Aristotle, as well as Kierkegaard's critique of preferential love and Erich Fromm's mystic interpretation of sexual relations. Section II covers current conceptions and practices of love. These chapters (...) explore how love changes over time, the process of falling in love, envy in romantic partnerships, and a new interpretation of grand-parental love. Finally, Section III looks at the future of love. These chapters address technological developments related to love, such as algorithm-driven dating apps and robotic companions, as well as the potential of polyamory as a future romantic ideal. This book will be of interest to researchers and advanced students in moral philosophy and social and political philosophy who are working on issues related to philosophy of love. (shrink)

In my article "berkeley's master argument" I attempt to show that an argument berkeley uses in the 'dialogues' and 'principles' to support his contention that whatever is perceivable is perceived can be seen as an illuminating attempt to relate conceptualizing, Imaging and perceiving. In consequence it cannot be dismissed as resting on an elementary fallacy, But reflects on the conditions for the self ascription of experience.

ABSTRACTOne of the recurrent motifs in political thought is the idea of the social contract, according to which a society, a government, or moral principles depend for their existence on agreements...

Resumo: Reconstruiu-se a semiologia geral elaborada nos escritos inacabados e indiretos de Saussure, recolocando sua noção de sentido próxima à de Deleuze e explicando-a por meio deste. Defende-se que toda teoria baseada na noção de “diferença” precisa dar conta do processo de individuação e, junto disso, por meio da descrição de dois níveis de diferenciação. Demonstra-se que isto é realizado por ambos os autores, para além e mesmo junto de suas divergências. Assim, o artigo recoloca a teoria do valor de (...) Saussure na aurora de uma filosofia da diferença, mostrando que este inaugura e mesmo “repete” as teses que Deleuze explicitamente defende, nos anos 1960.: The paper reconstruct the general semiology elaborated in Saussure’s unfinished and indirect writings, replacing his notion of meaning next to that of Deleuze, and explaining it through the latter. We argue that any theory based on the notion of “difference” needs to account for the individuation process and, together, through the description of two levels of differentiation. We demonstrate that this is accomplished by both authors, beyond and even with their disagreements. Thus, the article puts Saussure’s theory of value on the dawn of a philosophy of difference, showing that it inaugurates and even repeats the theses that Deleuze explicitly defends in the 1960s.

We show that the elementary theory of the recursively enumerable tt-degrees has the same computational complexity as true first-order arithmetic. As auxiliary results, we prove theorems about exact pairs and initial segments in the tt-degrees.

We prove that each Σ 0 2 set which is hypersimple relative to $\emptyset$ ' is noncuppable in the structure of the Σ 0 2 enumeration degrees. This gives a connection between properties of Σ 0 2 sets under inclusion and and the Σ 0 2 enumeration degrees. We also prove that some low non-computably enumerable enumeration degree contains no set which is simple relative to $\emptyset$ '.

The work of Joseph Delb??uf (1831‐1896), a philosopher, psychologist, and mathematician, provides fresh insights on the relationship between agency, consciousness, and evolution. Without agency, Delb??uf argued, the distinction between the self and the external world would be impossible, the function of feelings such as pain and pleasure would be incomprehensible, and consciousness would not have evolved. Delb??uf also posited a psychological stage of evolution, preceding that of natural selection, whereby sentient organisms influence the selection of their own traits through the (...) decisions they make during their reproductive lives. In relating these ideas and others, I show how Delb??uf’s work is relevant to current scholarship on the nature and evolution of consciousness. (shrink)

Ce texte synthétise les principaux résultats d’une enquête menée au Canada sur la tolérance des citoyens à l’égard du mensonge en politique. L’honnêteté est la valeur le plus importante pour les personnes interrogées, mais en même temps, beaucoup estiment acceptable de ne pas dire toute la vérité, surtout si les questions concernent la vie privée des politiciens. Par contre, lorsque les questions sont d’intérêt public, on est beaucoup moins tolérant.

Presenting a fascinating analysis of the idea of what can't be said, this book ascertains whether the notion of there being a truth, or a state of affairs, or knowledge that can't be expressed linguistically is a coherent notion. The author distinguishes different senses in which it might be said that something can't be said. The first part looks at the question of whether ineffability is a coherent idea. Part two evaluates two families of arguments regarding whether ineffable states of (...) affairs actually exist: the argument from mysticism and the argument from epistemic boundedness. Part three looks more closely at the relation between mystic and non-mystic stances. In the fourth and final part the author distinguishes five qualitatively different types of ineffability. _Ineffability and Philosophy_ is a significant contribution to this area of research and will be essential reading for philosophers and those researching and studying the philosophy of language.

We use Demuth randomness to study strong lowness properties of computably enumerable sets, and sometimes of Δ20 sets. A set A⊆N is called a base for Demuth randomness if some set Y Turing above A is Demuth random relative to A. We show that there is an incomputable, computably enumerable base for Demuth randomness, and that each base for Demuth randomness is strongly jump-traceable. We obtain new proofs that each computably enumerable set below all superlow Martin-Löf random sets is strongly (...) jump traceable, using Demuth tests. The sets Turing below each ω2-computably approximable Martin-Löf random set form a proper subclass of the bases for Demuth randomness, and hence of the strongly jump traceable sets. The c.e. sets Turing below each ω2-computably approximable Martin-Löf random set satisfy a new, very strong combinatorial lowness property called ω-traceability. (shrink)

Si les relations des Regulae avec leurs sources antiques ou médiévales ont été bien traitées, leur mise en place dans l'environnement immédiat laisse à désirer. Pourquoi n'a-t-on jamais mis ce premier ouvrage de Descartes en relation avec les "Dialectiques" qui font du xvie siècle un "siècle logique"? Une documentation surabondante prouve que ces logiques renaissantes sont tombées dans les oubliettes de l'histoire. De multiples courants rendent très vivant le développement de ces ouvrages consacrés à l'invention, au jugement et à la (...) méthode. Leurs profils deviennent forts apparents à qui les étudie. Or les Regulae, dont le profil typique exige la considération d'autres concepts que celui de méthode, épousent les schèmes conceptuels du ramisme, sans références à d'autres courants. D'où cette étude qui consiste à prendre pour point de référence la Dialectique française de La Ramée et à tendre l'axe critique et spéculatif qui ne cesse d'être tracé entre La Ramée et Descartes. Mais ce n'est pas là seulement une rétrospection créatrice : c'est aussi une nouvelle entrée dans la philosophie cartésienne de "la lumière naturelle". Les œuvres mûres seront à reconsidérer sous cet éclairage. (shrink)

The paper presents the main ideas of Ultrafilter Logic (UL), as introduced by Veloso and others. A new proposal, Normality Logic (NL), is outlined for expanding the expressive power of UL. The system NL appears to offer a simpler solution to the problem of expressive power than the sorting strategy of Carnielli and Veloso. Interpretations of NL are discussed and an important point of contact to Hansson's notion of non-prioritized belief revision is observed.

L'espace économique s'est profondément modifié au cours des vingt dernières années en raison, bien sûr, de la mondialisation, niais aussi de la déréglementation de nombreuses économies parmi les plus influentes du monde. D'une économie empirique de travail, nous sommes ainsi passés à une économie virtuelle de spéculation avec, à la clé, un recul de l'éthique au profit de logiques financières. C'est pour contrer les effets néfastes de cette financiarisation de l'économie que le mouvement de la finance socialement responsable s'est développé, (...) ses tenants utilisant les leviers économiques, en l'occurrence de nombreux fonds de placement, pour faire pression sur les décideurs et les orienter vers des avenues plus responsables. Ce livre présente le regard d'un philosophe et d'une sociologue sur ce mouvement. Les auteurs définissent les origines de la finance socialement responsable, pour ensuite exposer ses pratiques et ses stratégies, dresser un portrait de ses principaux acteurs et proposer des pistes de réflexion sur la dimension éthique de la finance ainsi que des outils pertinents aux pratiques des financiers. Il s'agit d'une introduction indispensable à tous ceux qui souhaitent s'initier au mouvement de la finance socialement responsable et qui recherchent des avenues éthiques en matière de développement économique.

Ainslie does not formally incorporate risk and uncertainty in his framework for modelling impulses and willpower. To provide a complete account of the motivational bases of choice behaviour, Ainslie should extend his framework to incorporate risk attitudes and subjective beliefs.

Em 1933, o Governo Provisório liderado por Getúlio Vargas criou o Conselho de Fiscalização das Expedições Artísticas e Científicas no Brasil, com o objetivo de coibir a saída do país de objetos de seu patrimônio natural e artístico e garantir uma parte do que fosse coletado no país para as instituições brasileiras. Num momento de aproximação do Brasil com os Estados Unidos, que competia com a Alemanha por influência no país mesmo antes da eclosão da Segunda Guerra, cientistas e outros (...) exploradores norte-americanos realizaram expedições para coleta de animais e outros objetos naturais, que foram exportados para enriquecer as coleções de museus e outras instituições científicas nos Estados Unidos. Nesse contexto, o Conselho não cumpriu propriamente seu trabalho de fiscalização. Em parte, isso ocorreu em benefício das relações diplomáticas com os norte-americanos; por outro lado, por interesses particulares e disputas institucionais que impediam o pleno exercício de suas funções. Ambos os fatores impediram um trânsito de conhecimento maior entre os dois países, como a incorporação de mais animais às coleções nacionais e um contato maior entre cientistas dos dois países. Além disso, caçadores e colecionadores usaram justificativas científicas para levar um sem-número de animais para o exterior. Os casos analisados neste trabalho demonstram como, mesmo um governo autoritário de inspiração nacionalista, não deu conta de impedir o afluxo de objetos do patrimônio natural para um país aliado. A tese busca mostrar, ainda, como as fronteiras entre caça e ciência eram borradas no período e como isso se refletiu na fiscalização do CFE. (shrink)

In this paper I examine Hume’s claims about the nature of moral sentiments (mainly in T 3.1.2) using as a foil the Kantian challenge to all material practical principles: they are all of the same type, being based on self-love and making all choices, including moral ones, hedonically fungible. The paper explores Hume’s views on pleasure as constitutive of moral sentiment as an answer to that challenge arguing that for him only pleasure is essentially valuable for beings like us. It (...) thus grounds a notion of value which, through a “progressive or dynamic” view of human nature, informs a conception of moral pleasure – a “taste in character traits” – as a distinctive type of pleasure that is not amenable to a mere quantitative criterium to guide moral choice. Keywords: Hume’s moral philosophy, moral sentiments, human nature, Kant. (shrink)

Traduction commentée de fragments araméens de Qoumrân contenant des restes de légendes sur les temps précédant le Déluge, insistant surtout sur les méfaits des Géants, nés des anges déchus et des filles de l’homme, et leur condamnation. Mis au nombre des écritures saintes du manichéisme, le « livre des Géants » a été traduit en des langues diverses et on en a retrouvé des vestiges à Tourfân. Ils sont rapprochés ici de leur original araméen. Translation and commentary on the Aramaic (...) fragments from Qumran , which include the remainders of legends about the period before the Flood, mainly about the wrongdoings of the Giants who were born from fallen angels and the daughters of men, and their condemnation. Since the « Book of the Giants » was included among the holy scriptures of Manichaeism, it has been translated into several languages. Traces of it have been found, for instance, in Turfan. This paper establishes their connection with the Aramaic original. (shrink)
