Starting from David Hume's analysis on the notion of justice in his main work on the topic, his 'Treatise of Human Nature', the author sets out, firstly, to comment on Hume's explanation on the notion of justice as a nonarbitrary artifice resulting from men's conventions, and then to outline the value system which determines the theory of justice of the Scottish philosopher. Finally, a criticism is presented on Hume's supposedly "nonarbitrary" conception of justice and the existing link between his (...) empirical deduction and the nominalist explanation of justice.

The negative zombie argument concludes that physicalism is false from the premises that p ∧¬q is ideally negatively conceivable and that what is ideally negatively conceivable is possible, where p is the conjunction of the fundamental physical truths and laws and q is a phenomenal truth (Chalmers 2002; 2010). A sentence φ is ideally negatively conceivable iff φ is not ruled out a priori on ideal rational reflection. In this paper, I argue that the negative zombie argument is neither a (...) priori nor conclusive. First, I argue that the premises of the argument are true only if there exists an adequate finite ideal reasoner R that believes ◊(p ∧ ¬q) on the basis of not believing p→q on a priori basis. Roughly, a finite reasoner is a reasoner with cognitive limitations (e.g. finite memory). I argue that R is finite only if R reasons nonmonotonically and only approach ideal reflection at the limit of a reasoning sequence. This would render the argument nonconclusive. Finally, I argue that, for some q, R does not believe ◊(p ∧ ¬q) on the basis of not believing p→q on a priori basis (e.g. for q =‘something is conscious’). This would render the choice of an adequate q dependent on empirical information (and the argument a posteriori). I conclude that the negative zombie argument (and, maybe, all zombie arguments) is neither a priori nor conclusive. (shrink)

The most widespread models of rational reasoners (the model based on modal epistemic logic and the model based on probability theory) exhibit the problem of logical omniscience. The most common strategy for avoiding this problem is to interpret the models as describing the explicit beliefs of an ideal reasoner, but only the implicit beliefs of a real reasoner. I argue that this strategy faces serious normative issues. In this paper, I present the more fundamental problem of logical omnipotence, which highlights (...) the normative content of the problem of logical omniscience. I introduce two developments of the notion of implicit belief (accessible and stable belief ) and use them in two versions of the most common strategy applied to the problem of logical omnipotence.

O autor analisa a posição de Antero de Quental perante o movimento iberista do século XIX, destacando a origem peninsular deste e a sua tradição, com raízes no liberalismo. Aponta a influência nesse movimento de um proudhonismo ingénuo, e destaca o papel de José Félix Henriques Nogueira como transmissor de um ideal federativo com base na concepção de uma "pátria espanhola comum", em que a federação tende no limite paraa fusão.A propósito conclui que a formulação dada por Antero a este (...) pensamento, em Portugal perante a Revolução de Espanha não é mais radical que a de Nogueira, antes é uma consequência contida no pensamento deste precursor do republicanismo. Por outro lado, Teófilo Braga, além de partilhar do ideal liberalista, advogou a separação dos Açores do continente português, contrariamente a Antero de Quental, que pensava que os açorianos só podiam ser portugueses, devendo entrar, federados com o Continente, num estado ibérico. /// L'auteur analyse la position de Antero de Quental devant le mouvement ibériste du XlX.e siècle, en mettant en relief son origine péninsulaire et sa tradition enracinée dans le libéralisme portugais. Il remarque l'influence sur ce mouvement d'un proudhonisme naïf et met en relief l'importance de José Félix Henriques Nogueira en tant que diffuseur d'un idéal fédératif basé sur la conception d'une "patrie espagnole commune", dans laquelle la fédération, à la limite, tend vers la fusion. À ce propos il remarque que la formulation donnée à cette pensée par Antero dans Portugal perante a Revolução de Espanha n'est pas plus radicale que celle de Nogueira; elle est plutôt une conclusion contenue dans la pensée de ce précurseur du républicanisme portugais. Par ailleurs, Teófilo Braga non seulement partagea l'idéal ibériste, mais il a été partisant de la séparation des Açores du Portugal continental, contrairement à Antero de Quental, qui jugeait que les Açoréens ne pourraient être que Portugais, et devraient entrer en fédération avec le Portugal ibérique dans un état péninsulaire. /// The author analises the position of Antero de Quental within the Iberist movement of the XlXth century and emphazises its Peninsular origin and its tradition with roots in the Portuguese Liberalism. He points to the influence in this movement of a certain naive proudhonism and the rêle of José Félix Henriques Nogueira as a transmitter of a federative ideal based on the conception of a "common Spanish fatherland" in which the federation tends at the limit towards fusion. In this context he concludes that the formulation given by Antero in the opuscule Portugal perante a Revolução de Espanha is no more radical than that of Nogueira; it is rather a consequence of the thought of that forerunner of the republicanism in Portugal. On the other hand Teófilo Braga not only shared the Iberist ideal, but also defended the separation of the Azores from the Portuguese homeland, contrarily to Antero de Quental, who thought that the Azoreans could only be Portuguese and that they should accede to an Iberian state federated with the mainland.

We performed an EEG graph analysis on data from 31 typical readers (22.27 ± 2.53 y/o) and 24 dyslexics (22.99 ± 2.29 y/o), recorded while they were engaged in an audiovisual task and during resting-state. The task simulates reading acquisition as participants learned new letter-sound mappings via feedback. EEG data was filtered for the delta (0.5–4 Hz), theta (4–8 Hz), alpha (8–13 Hz), and beta (13–30 Hz) bands. We computed the Phase Lag Index (PLI) to provide an estimate of the (...) functional connectivity between all pairs of electrodes per band. Then, networks were constructed using a Minimum Spanning Tree (MST), a unique sub-graph connecting all nodes (electrodes) without loops, aimed at minimizing bias in between groups and conditions comparisons. Both groups showed a comparable accuracy increase during task blocks, indicating that they correctly learned the new associations. The EEG results revealed lower task-specific theta connectivity, and lower theta degree correlation over both rest and task recordings, indicating less network integration in dyslexics compared to typical readers. This pattern suggests a role of theta oscillations in dyslexia and may reflect differences in task engagement between the groups, although robust correlations between MST metrics and performance indices were lacking.

ResumoEste ensaio examina a sobrevida textual de uma cabeça — a de Antônio Vicente Mendes Maciel, o Antônio Conselheiro (1830-1897), a partir de sua morte na Guerra de Canudos (1896-1897). Traçam-se as figurações do crânio de Conselheiro na imprensa brasileira do fim do século XIX e nos trabalhos do médico legista Raimundo Nina Rodrigues e do engenheiro e escritor Euclides da Cunha. Embora ambos esperassem que o crânio de Conselheiro apresentasse evidências físicas de degeneração racial, as observações craniométricas de Nina (...) Rodrigues revelaram um crânio normal. Argumenta-se que esse fracasso da aproximação materialista à psique humana deu proeminência a explicações sociológicas para o fenômeno de Canudos, além de levantar questões sobre visibilidade, raça e racismo científico na virada do século XX e no mundo contemporâneo.Palavras-chave: Raça. Psiquiatria. Guerra de Canudos. Antropologia criminal. AbstractThis essay examines the textual afterlife of a head—that of Antônio Vicente Mendes Maciel (Antônio Conselheiro [1830-1897]), after his death in the Canudos War (1896-1897). It traces figurations of Conselheiro’s skull in the late nineteenth-century Brazilian press and in the works of Raimundo Nina Rodrigues and Euclides da Cunha. Although these two social scientists expected Conselheiro’s skull to display physical evidence of racial degeneration, Nina Rodrigues’s craniometric measurements and observations revealed a perfectly normal skull. It is argued that this failure of a materialist approach to the human psyche allowed a stronger reliance on sociological explanations for the Canudos phenomenon that opens up questions on scientific racism and the visibility of race in the turn of the twentieth century and in contemporary times.Keywords: Race. Psychiatry. Canudos War. Criminal Anthropology. (shrink)

The notion of an ideal reasoner has several uses in epistemology. Often, ideal reasoners are used as a parameter of (maximum) rationality for finite reasoners (e.g. humans). However, the notion of an ideal reasoner is normally construed in such a high degree of idealization (e.g. infinite/unbounded memory) that this use is unadvised. In this dissertation, I investigate the conditions under which an ideal reasoner may be used as a parameter of rationality for finite reasoners. In addition, I present and justify (...) the research program of computational epistemology, which investigates the parameter of maximum rationality for finite reasoners using computer simulations.

En el presente trabajo se analizan los conceptos hegelianos de sociedad civil y Estado, ámbitos donde el hombre —burgués y ciudadano— desarrolla los diversos aspectos de su singularidad y su vocación por lo universal. Se tratará de ahondar en la vertiente ética que abarca la vida del hombre como individuo y como ciudadano, y que, dadas las condiciones del mundo moderno, participa de la vida típica de un sujeto que goza de su libertad esencial y originaria en dos esferas complementarias, (...) a la vez que necesarias, para poder desenvolver su libertad en plenitud: las actividades que como particular lleva a cabo en la “sociedad civil” y las que también ejerce como un sujeto comunitario, dotado de capacidades éticas, con participación en la vida política de su Estado.

Se comprende por "contractualismo" la teona por la cual se explica y justifica el fundamento y la posibilidad de la sociedad a partir de un pacto entre sus miembros y que es desarrollado en toda su expresión en la Modemidad.

Tras una breve semblanza del autor y de su obra, se incluye la traducción de un pasaje del Libro de los animales en el que al-Yâhiz alude a la versión de una lengua a otra y se comentan algunas cuestiones planteadas por la moderna teoría de la traducción en relación al mismo.

Resumen: En el presente ensayo nos apoyaremos en algunos escritos fundamentales de Talcott Parsons, especialmente en lo referente a su disputa epistemológica contra el empirismo, para luego mostrar sus propias inconsistencias e ir más allá de él en la propuesta de una forma novedosa de trabajo teórico para las ciencias sociales: la teorización sistemática dinámico-estructuralista, como distinta a la teoría sistémica funcional-estructural. La idea principal es trascender las posturas representacionalistas y antiteoricistas en pos de miradas teóricas abiertas a la crítica (...) y la autocrítica. Así, frente a una mirada que confunde distintas dimensiones del continuo empírico-metafísico sin otorgarles su relativa autonomía analítica, que a nivel teórico-social y de modelos de la sociedad piensa en términos funcionales y sistémicos, que considera que cada uno de sus conceptos refiere de manera cabal a dicho mundo social y que cree que es factible la construcción de teorías acabadas, nuestra mirada busca distinguir dimensiones, complementar tradiciones plurales, y mantenerse siempre abierta a la crítica externa y la autocrítica.: In this essay we will rely on some of the key writings of Talcott Parsons, especially with regards to his epistemological dispute against empiricism, to show his own inconsistencies and go beyond him in proposing a new form of theoretical work for the social sciences: systematic and dynamic-structuralist theorizing, as distinct from functional-structural systemic theory. The main idea is to transcend the representationalist and anti-theoretical positions in favour of a view of theory open to criticism and self-criticism. In this way, and against those outlooks that confuse the different dimensions of the empirical-metaphysical continuum without giving them their relative analytic autonomy, that think in terms of functions and systems when talking about models of society, that consider each concept to be a representation of the social world, and that believe theories can be closed for good, our own outlook seeks to distinguish dimensions, complement plural traditions, and stay open to external critique and self-criticism.

Una escueta visión histórica de la filosofía política analizada desde el punto de vista de la teoría del derecho y de la sociedad, nos permite ver cómo ha ido desarrollándose, desde Ockham, y actualmente hasta filósofos liberales como Rawls, una concepción de la justicia fundada en el hecho contractual, dispositivo mediante el cual se establece un determinado orden en la sociedad, orden basado en una noción artificial (construida) de la justicia. Hobbes se constituye en el momento clave del giro copernicano (...) de la cuestión, con su idea convencional de justicia. Luego el utilitarista Hume elabora las llamadas ¿circunstancias de la justicia¿, también convencionales, argumentación que influirá finalmente en Rawls en su idea de ¿sociedad bien ordenada¿.

This article presents research on assemblages among humans and computational systems in which physical and virtual autonomous processes occur in order to create artworks allowing the emergence of mixed sensory set-ups. It begins with triadic relationships computer, physical objects and participants aimed at co-relations among bands of bots (virtual and physical) with groups of humans (interactors). The bots have a representation of the virtual world: physical bots live on a flat surface (Abbot 1991), a projection of the 3D environment where (...) the virtual bots live. The artwork also explores the metaphor of higher dimensions being understood through their projections in lower dimensions. Its goal is to weave interaction and autonomous processes, looking for poetic results integrating art, science and technology; results with aesthetic, poetic and functional qualities; and results exploring emergency and agency for design, construction and set-up of expressive systems. For these symbioses to happen the assemblage of environments with aesthetic and poetic appeal leads one to think about mixed cognitive processes that provoke emergent behaviours. I am interested in the behaviours emerged in such inter-relationships. Therefore, to achieve this goal, I have created a Java framework that allows me to program interfaces weaving such behaviors1 and also I have programmed a set of sketches using Processing2 to test the hypothesis. The main inquiries of such research are as follows: What kind of artwork could mix people with autonomous computational processes without becoming invasive? and Is such a dichotomy possible? To answer these questions, I came up with the idea of playing with swarms and flock algorithms mixing virtual and physical domains. Will this create the mixed behaviour I am looking for? Will the participants contribute with their actions, emotions and affects while the computer develops its own autonomous processes? (shrink)

Os sentidos evocados pelo termo “Mundo” sofreram um contínuo deslocamento na tradição poético-filosófica ocidental. Enfocando a noção de Mundo, conforme exposta nos episódios de “abertura da Máquina do Mundo”, veremos como essa noção evoluiu em contradição à astronomia ptolomaica, seu modelo anterior. Com o avanço do conhecimento científico e com novas considerações filosóficas e metafísicas, capitaneadas por Giordano Bruno, a concepção de Mundo abandonou sua prévia centralidade humana, aproximando-se do conceito de Universo. Dois são os movimentos de deslocamento enfocados neste (...) trabalho: o de descentramento do humano e o de abertura para o infinito. (shrink)
