The aim of this paper is to clarify the truth-functional interpretation of the logical connective of the material implication. The importance of such clarification lies in the fact that it allows avoiding the supposed paradoxes introduced by C. I. Lewis (1918). I argue that an adequate understanding of the history and purposes of logic is enough to dissolve them away. The defense is based on an exposition of propositional compositionalism. To compare, I also present Stalnaker’s (1968) alternative that seeks to (...) explain the implicit concept of conditionality of conditionals assertions. In order to reinforce my aim I expound the twelve different meanings of ‘implication’ stated by Corcoran (1993) in order to hold that a proper understanding of these meanings allows us to avoid ambiguities and confusions. Finally, I expect to show that despite the possible alternatives, compositionalism is still the best explanation for the truth-functionality account of logical connectives. (shrink)

Philosophical problems about the part-whole relation have been discussed throughout the history of philosophy, at least since Plato and Aristotle. In contemporary philosophy, the understanding of these issues has benefited from the formal tools of Classical Extensional Mereology. This paper aims is to defend mereological restrictivism against some constraints imposed by the vagueness argument. To achieve this, the paper is divided into three parts. In the first, I introduce the special composition question (hereafter SCQ) as formulated by [Van Inwagen, 1990] (...) and briefly present the three sets of theories that proffer answers to it. In the second part, I focus on the vagueness argument, that was presented by [Lewis, 1986, ] and [Sider, 2007, ] to defend mereological universalism. In the third section, I introduce the theory of natural properties by David Lewis. From this theory, I propose a new mereological operation labeled as natural fusion. The purpose of this operation is to falsify one of the premises of the vagueness argument. Then, I discuss some examples and counter-examples to natural fusion. (shrink)

I argue in this dissertation that natural properties play a central role in David Lewis' modal realism. To argue in favor of this thesis I present: a bottom-up explanation of a top-down possible world metaphysics; a new definition of natural properties and natural fusion, a new mereological operation. To achieve these aims, in the first chapter, I contextualize the discussion, in the second I resume the discussion about universals in contemporary philosophy and argue that, considering the distinct formulations of the (...) problem, class nominalism combined with modal realism might be the best solution. Furthermore, I discuss Devitt's solution in which he defends that the problem about universals is, in fact, a pseudo problem. In the third chapter, I introduce a minimal ontology of properties, regarding natural properties, I discuss the existing definitions, present a new one and discuss some theories of similarity, a notion that is in the core of the definition I propose. Besides, I present how natural properties benefit the definition of terms of nomological package, linked to its fundamentality role. I also present some applications related to the rationality role that encompass some well-known philosophical problems of the second half of 20th century. In the fourth chapter, I present some varieties of philosophical realism, I consider the theoretical advantages of taking scientific realism as background and I discuss one more utility of natural properties, the solution to the problem of eligibility of reference or, the Putnam's paradox. In the fifth chapter, I discuss how mereology is important to link several aspects of Lewis' modal realism. For such, I discuss the relation between composition as identity and ontological innocence of mereology and I present the natural fusion mereology, a new mereological operation that aims to minimize the problems of unrestricted composition.

I present in this note an alternative answer to the princesses' earring problem, found in the first chapter of Cezar Augusto Mortari's book "Introdução à Lógica”.

Essa comunicação possui dois objetivos. Em primeiro lugar, pretendo esboçar as diferentes alternativas teóricas contemporâneas que procuram responder ao conhecido “ problema dos universais”. Para isso, apresentamos os nominalismos de predicados, classes, semelhanças e a teoria de tropos. Em segundo lugar, pretendo mostrar, inspirado no trabalho de David Lewis, como o nominalismo de classes, a noção de propriedade natural e uma teoria de mundos possíveis prometem resolver o problema em questão.

Objetiva-se com este artigo uma breve investigação sobre a relação existente entre Fé e Razão, especificamente no que toca à compreensão do intellectus fidei e da ratio fidei enquanto desdobramento temático. De acordo com a Carta Encíclica Fides et Ratio, a Fé e a Razão se assemelham a duas asas com as quais o espírito humano se eleva à contemplação da verdade. O desejo de conhecimento da verdade e, por conseguinte, de Deus e de si próprio é apontado como uma (...) vocação divina colocada no coração do homem por Deus. Embora as questões de fé possam passar por um tratamento racional, a fé possui a sua inteligência própria, específica não se limitando a esquemas relativos à razão demonstrativa, científica ou discursiva.

Several countries maintain universal health coverage, which implies responsibility to organize delivery formats of healthcare services and products for citizens. In Brazil, the health system has a principle of universal access for more than 30 years, but many deficiencies remain and the country observes a day practice for those seeking judicial decisions to determine provision of healthcare.

Paulo Mendes da Rocha (né en 1928, lauréat du prix Pritzker en 2006) est l’un des grands architectes de notre temps. Auteur d’une œuvre encore mal connue hors du Brésil, il est également un théoricien de l’architecture tout à fait original. Cet article vise à présenter synthétiquement les grands thèmes de cette pensée en architecture qui entretisse sans cesse esthétique et politique sous le mot d’ordre d’une architecture « opportune ».

This schedule, provided as a companion to my “Teaching Firefly” article, was used for a sophomore level philosophy course that was populated mostly by non-majors. The original idea for the course was to develop a popular culture philosophy course that would attract students from all over campus, which was meant to both introduce them to multiple philosophical ideas and theories and hopefully convince some of them to major or minor in philosophy. The course was quite successful at drawing Whedon fans (...) from across the university (after a certain amount of advertising through posters and social media). Students were very engaged with both discussions of episodes and the readings. (shrink)

BIOGRAFIAS NÃO AUTORIZADAS: UMA DISCUSSÃO INÓCUA NO BRASIL?

Educazione o sublimazione estetica? : il "bello" in Schiller -- Dionisio contro Socrate : la "Nascita della tragedia" di Nietzsche.

The combination of single material elements characterises Nespolo’s artworks since the 60s. The primacy of art factuality - to do art manually - emerges both in his geometrically structured works and in his machines and wooden uniconic structures. These are all combined and based on the strategy of puzzle and on a reflection about the mental attitude to do art. For these reasons, it is possible to consider Nespolo as a forerunner of Conceptual Art.

Noting that one may hear without listening, the article probes the phenomenological and epistemic distinction between hearing and listening. To listen is to be attuned to voices muffled by silence or camouflaged by a defensive rhetoric resonant with a voice inflected by festering wounds, existential and political. In exploring how one is to listen to these voices of silence, I draw upon Martin Buber’s concept of dialogical “inclusion” of others’ stories, to listen without interpretation to allow the voice behind his (...) – or her or their – story, be it merely etched viscerally in the language of silence, to dwell aside one’s own story in a dialogue unencumbered by perceptions of the Other forged by cultural, social, political constructs, and perhaps most insidiously one’s own defensive postures.

Diz o ditado que "quem não gosta de samba, bom sujeito não é: ou é ruim da cabeça ou doente do pé". Os filósofos tradicionalmente são doentes do pé e muitos deles certamente são ruins da cabeça. Isso parece tornar o tema desse livro pouco viável. Entretanto, tentamos mesmo assim. Afinal gente ruim da cabeça também é inconsequente. Na verdade, esse livro é a continuação do desejo compartilhado por seus diversos autores de aproximar a filosofia da cultura brasileira. E nada (...) melhor para tornar esse diálogo palpável do que o motivo fornecido pelo samba. Afinal, ele é uma de nossas manifestações nacionais mais típicas, difundidas e que tem sobrevivido a várias transformações ao longo do tempo. Através desse livro, esperamos ter nos tornado menos doentes do pé e menos ruins da cabeça -- apesar de quase todos gostarem de samba. (shrink)

ATIVIDADE CURRICULAR EM COMUNIDADE E SOCIEDADE E OS POVOS TRADICIONAIS: EXPERIÊNCIA DE CAMPO DO CURSO DE DIREITO DA UNIVERSIDADE FEDERAL DA BAHIA.

La siempre fascínate escritura rulfiana continúa dialogando con el mundo. El así conocido “escritor de las letras mexicanas”, nos sigue ofreciendo un mar de posibilidades de acercamiento a otras áreas humanísticas entre las cuáles incluimos a la filosofía. Coincidentes en la época y en la geografía mexicana, Juan Rulfo y María Zambrano se encontraron en 1939. Exponentes ejemplares y creadores de nuevos caminos en la escritura literaria y filosófica, los exponemos como paralelos a través de dos piezas claves de sus (...) obras: Pedro Páramo y Los sueños y el tiempo. La antropología zambraniana viene propuesta como uno de estos senderos creativos y creadores de la búsqueda del propio ser y del sentido mismo del existir. Dicho pronunciamiento antropológico lo exponemos como perspectiva de lectura del viaje no sólo de Juan preciado, ansioso buscador de su padre, sino de todos los lectores de Rulfo que hemos tejido con sus letras —extractoras de sueños y productoras de anhelos— la frágil cuerda que sostiene la aventura del descubrir nuestro lugar en el oscuro pozo del mundo. Realismo mágico y Razón poética en armonía propositiva que revela el origen de ambos proveniente de la misma semilla del ser. Rulfo y Zambrano nos enseñan que hay encuentros más profundos y reales que aquellos sólo históricos. (shrink)

Philosophers unknowingly subscribe to two competing conceptions of philosophy. On the inclusive conception, teaching philosophy provides a valuable social good that should be distributed as much as possible. On the traditionalist conception, certain materials and techniques constitute the way philosophy should be taught, which must be conserved. Unfortunately, the traditionalist conception clings to methods that have repeatedly produced an elitist, hierarchal version of philosophy that inhibits diverse engagement. Given the value of philosophy, philosophers have a duty to distribute philosophy to (...) a greater number of people, which requires embracing the inclusive conception. Acting towards this duty can be done by working beyond the classroom, spreading philosophy through service, and improving our teaching both to reach a more diverse audience and to follow pedagogical research, such as with experiential learning techniques. Philosophers should also ensure that the duty’s burden falls more on privileged philosophers who can take on the necessary sacrifices. (shrink)

While virtually everyone recognizes the moral permissibility of whistleblowing under certain circumstances, most theorists offer relatively conservative accounts of when it is allowed, and are reluctant to offer a full recommendation of the practice as an important tool towards addressing ethical failures in the workplace. We think that accounts such as these tend to overestimate the importance of professional or personal obligations, and underestimate the moral obligation to shine light on severe professional malfeasance. Of course, a whistleblower, even an anonymous (...) one, often faces serious threats of retaliation and harm to their professional livelihoods and well-being. To address these challenges we argue in favor of a practice that we will call Preemptive Anonymous Whistleblowing (PAW). Such whistleblowing is preemptive in that a whistleblower provides information about malfeasance to a party in a position to do something about it without first raising the worry to one’s immediate superiors. At first blush, such preemption may seem unsettling, and PAW admittedly raises a number of worrisome issues. We defend PAW, however, as part of a larger argument that whistleblowing is morally required more often than is commonly thought. The availability of PAW as an option provides a method for allaying the concern that whistleblowing can be overly burdensome due to the risks of job and career. Insofar as that concern can be allayed, it is feasible for there to be substantial moral requirements to engage in whistleblowing in cases where severe harms can be prevented. With high enough stakes, there is a moral requirement for whistleblowing. (shrink)

Esse artigo pretende explorar os temas do estatuto e da função do intelectual em dois autores significativos para a questão a partir do século XX: Julien Benda e Jean-Paul Sartre. Trata-se de revisitar as noções de autonomia e engajamento, fundamentais para uma compreensão comparativa entre os dois autores. O texto procura caracterizar de forma ampla o tipo de intelectual defendido por Benda no mesmo passo em que procura evidenciar a gênese e as condições de aparecimento do intelectual para Sartre. O (...) Caso Dreyfus, momento histórico de surgimento do intelectual como o conhecemos, é revisitado a fim de estabelecermos um referencial concreto para as posições dos autores em discussão. A partir dos elementos levantados, procura-se argumentar no sentido das divergências entre Benda e Sartre sobre a natureza e o papel do intelectual, mas também propõe-se evidenciar o solo comum em que os dois autores parecem trafegar. O texto, ainda, aponta questões para se pensar o intelectual a partir das novas condições políticas e sociais na contemporaneidade. (shrink)

Nesse artigo, empreenderemos uma reflexão sobre a analítica do poder em Michel Foucault. Nossa intenção é percorrer a produção foucaultiana a partir de meados dos anos setenta até início dos anos oitenta, buscando compreender os deslocamentos ou “reviravoltas” pelos quais o conceito de poder sofreu ao longo do tempo. Procuraremos mostrar que é possível identificar três momentos na pesquisa de Foucault. Em primeiro lugar, ao tentar se afastar da tradicional compreensão jurídica-discursiva do poder, ele introduz uma análise inédita a respeito (...) da dinâmica do poder disciplinar e dos micropoderes que compõem o campo social. Pode-se considerar esse um deslocamento, de modo geral, em relação à tradição política ocidental. Com o curso Em defesa da sociedade encontramo-nos diante de uma modificação na compreensão do poder, ao identificá-lo como guerra ou luta. Por fim, com a introdução dos conceitos de biopoder/biopolítica, Foucault é levado a uma grande expansão de suas pesquisas, tematizando conceitos que não faziam parte de seu interesse até então, como, por exemplo, o conceito de Estado. É nesse contexto que o conceito de governo fará sua entrada nas reflexões de Foucault. Entendemos que o conceito de governo se configura como um refinamento e, igualmente, deixa mais ampla e complexa sua análise do poder a fim de dar conta do presente político. (shrink)

The question whether compulsory schooling is justifiable or not has been treated at considerable length by critics, defenders, and positions in-between. What these treatments—about paternalism and autonomy and institutionalization and more—have not directly analyzed is a question that precedes the issue of overall justification: the preliminary question of time. Does it matter when compulsion takes place? Furthermore, does the timing of compulsion matter to the question of overall justification? I will argue that it does matter, but for reasons not directly (...) related to the question of overall justification. (shrink)

Deep beneath the Jack the Ripper story, Alan Moore and Eddie Campbell use From Hell to argue for a philosophical thesis: Although physical violence and structural violence are quite different, they are also interconnected as each causes the other to worsen. William Gull claims that through the Ripper murders, he has “delivered” the twentieth century, as seen in his premonition of the mundane office place. In other words, Gull believes that the Ripper murders somehow played a foundational role in creating (...) twentieth-century life. This premonition suggests that horrific murders like those of the Ripper make structural violence, such as that found in the contemporary office place through wrongs such as sexual harassment, recede into the background of society where it becomes invisible and taken for granted. As Gull sees his violence as particularly connected to his misogynist worldview, From Hell makes the clearest case for the connection between physical violence and structural violence through the problem of patriarchy.

Is there room for philosophy in educational research? Is there phenomenology before and beyond its uses and abuses in the applied and social sciences? How are phenomenology and philosophy of education related? What are the methods for phenomenology within the field of philosophy of education? These talks to educational scholars and researchers responds to these questions and appeals for place of philosophy within educational research and the tradition of phenomenology within philosophy of education. Across a genealogy of thought and frequent (...) autobiographical confessions, this book of lectures works from the simple insight that philosophy and education are not so different. (shrink)
