We show that the E + -class can be decided by resolution using a liftable order, when the order is applied a posteriori. This is a surprising result, because the decision procedure for the E + -class was one of the motivations for the study of non-liftable orders. Also surprising is the behaviour of the resolution process. Initially the maximal depth at which a variable occurs can increase, but it will not increase more than a certain bound. We do not (...) make use of any type of saturation rule in our resolution strategy. (shrink)

We provide a simple translation of the satisfiability problem for regular grammar logics with converse into GF2, which is the intersection of the guarded fragment and the 2-variable fragment of first-order logic. The translation is theoretically interesting because it translates modal logics with certain frame conditions into first-order logic, without explicitly expressing the frame conditions. It is practically relevant because it makes it possible to use a decision procedure for the guarded fragment in order to decide regular grammar logics with (...) converse. The class of regular grammar logics includes numerous logics from various application domains. A consequence of the translation is that the general satisfiability problem for every regular grammar logics with converse is in EXPTIME. This extends a previous result of the first author for grammar logics without converse. Other logics that can be translated into GF2 include nominal tense logics and intuitionistic logic. In our view, the results in this paper show that the natural first-order fragment corresponding to regular grammar logics is simply GF2 without extra machinery such as fixed-point operators.

Segundo o presente artigo, a crise ecológica tornou dramaticamente claw que a evolução social não deve ser apenas entendida como uma emancipação das limitações derivadas da natureza e das amarras da sociabilidade humana e ainda menos deve ser aferida pela capacidade de transformar a natureza num mew repositório de recursos naturais capazes de garantir a sobrevivência do género humano. O artigo pretende assim mostrar até que ponto o progresso social está intimamente associado com a capacidade de se manter o metabolismo (...) social com a natureza a um nível regenerativo. Precisamente neste contexto é que deve ser entendida a exigência de se associar intimamente os sistemas funcionais da economia e da técnica na rede natural que os suporta e dessa forma condicionar a direcção estàvel da evolugdo social á capacidade de resistencia, sempre em mudança, dos sistemas ecológicos. Nesse sentido, o autor define a tarefa de uma "ética social ecológica" como sendo a de contribuir para a clarificação da necessária e, diante da razão prática, responsdvel articulagdo mutua dos factores económicos, sócio-culturais e ecológicos. Essa "ética social ecólogica", diz ainda o autor, parte da constatação de que com a modernidade se alcançou um estádio da história da cultura em que a dependência do ser humano em relação a natureza está ligada com uma dependência de muitos ecosistemas, até então deixados em seu estado natural, em relação ao ser humano, de cuja integridade, por sua vez, também o ser humano depende. Porfim, o artigo interroga-se sobre até que ponto numa natureza de tal maneira "socializada" ainda se podem encontrar pressupostos para uma praxis social capaz de apontar um caminho racionalmente induzido em que se garanta ofuturo dos sistemas sociais, e mostra como esta questão conduz ao problema ético-ecológico fundamental relativo á existência de aspectos normativos no relacionamento com a natureza nas sociedades modernas. /// In the view of the present article, the ecological crisis has dramatically demonstrated that social evolution ought not be understood merely in terms of an emancipation of natural and social limitations. Even less, ought it be thought that such an emancipation implies the transformation of nature into just a reserve of natural resources for the survival of humankind. The article hopes to show the degree to which social progress is intimately associated with the capacity of maintaining the social metabolism with nature at the level at which regeneration is possible. One must come to understand the exigency of bringing functional systems of economy and technology within the natural network nature that supports them such that an equilibrium in social evolution may be established in relation to the ecological systems. In this sense, the author sees the task of an "ecological social ethics" as contributing to the clarification of the necessary articulation between economic, socio-cultural, and ecological factors. Such an ethics is conceived against the background of a modernity that reflects a stage in the history of culture in which human beings were seen as depending on many ecosystems left in their natural state. Finally, the question is raised concerning the degree to which it is still possible to find principles for a social praxis capable of opening a rational path for the social systems of the future and how this question raises a further one about the normative aspects of the relationship with nature in modern societies.

Émile Durkheim remains one of the most controversial, and deeply misunderstood, classics of social theory. His work differs from the dominant version of sociology that has essentially accepted the modernist self-description of contemporary societies; and it contradicts the individualism that has come to dominate the social sciences. For everybody who is interested in constructing theoretical alternatives to this individualism, Durkheim's sociology can be a useful inspiration - not only because of the solutions it suggests, but already because of the questions (...) it asks. Making use of the theoretical possibilities offered by the Durkheimian tradition, however, requires going beyond the familiar appropriations. The Oxford Handbook of Émile Durkheim takes stock of the different recent debates on Durkheimian sociology, and makes them accessible to a wide audience spanning various disciplines; this includes crucial debates that, due to language barriers, are not easily accessible for an English-reading public. The handbook's chapters elucidate the controversial key concepts of Durkheimian sociology; situate them within the contemporary political and theoretical debates they were originally responding to; offer surveys of empirical research that uses Durkheimian concepts (on topics that were already central for Durkheim's own work as well as on topics that Durkheim hardly touched upon), thus demonstrating the possibilities of a Durkheimian sociology; bring out the divergent, and competing, ways in which Durkheim's ideas have been appropriated and reformulated within more recent theoretical developments in the social sciences. In doing so, this volume is an important resource for all scholars and students looking to understand Durkheimian sociology. (shrink)

El presente trabajo tiene como fin describir la relación entre retórica y hermenéutica en la obra de Hans-Georg Gadamer. Un primer paso consiste enreconocer los elementos de la retórica en el contexto de Verdad y Método.Apartir de allí se intentará mostrar lo que Gadamer entiende por la recuperación hermenéutica de la retórica antigua sobre la base de tres tópicos. Elprimero radica en mostrar que la retórica, al igual que la hermenéutica, alcanzaun estatus ontológico. En segundo lugar, que la retórica (...) es parte fundamentalen la formación de los conceptos mediante el elemento de la analogía.Y en tercer lugar, la íntima relación que mantiene la hermenéutica con laretórica a un nivel de argumentación racional sobre la base de la noción deverosimilitud (eikós).

En este trabajo se expone y comenta esquemáticamente la biofilosofía de Hans Jonas, poniéndola en relación con su visión del ser humano. Para Jonas la vida se distingue de la materia inerte por la libertad ganada desde la aparición del metabolismo. Percepción y emoción generan un hiato o mediatez entre el interés animal y su satisfacción; la conducta animal sería, entonces, el segundo grado de libertad. Con el ser humano surge un nuevo grado de libertad, que implica un salto (...) ontológico caracterizado por el autor como transanimalidad. Lo transanimal remite a un modo propio de apropiarse del mundo, que se distancia de la satisfacción de las necesidades meramente biológicas, que no reviste utilidad para él, y que lo lleva a encontrarse consigo mismo y reflexionar sobre su propia existencia. En este plano Jonas examina tres signos de lo humano: la herramienta, la imagen y la tumba. La antropología de Jonas entronca con su comprensión de la realidad natural como fenómeno vivo y con su fenomenología de la vida animal. Este planteamiento de Jonas nos parece original y fecundo. Sus aportes iluminan la paleontología contemporánea, aportan criterio para juzgar el nivel de desarrollo humano en toda época y aportan una base sólida donde poder anclar una metafísica. (shrink)

In 1890 C. S. Peirce wrote a review of A. C. Fraser’s recent book on Locke, published to coincide with the bicentennial of Locke’s Essay. Peirce remarked that “Locke’s grand work was substantially this: Men must think for themselves, and genuine thought is an act of perception…. We cannot fail to acknowledge a superior element of truth in the practicality of Locke’s thought, which on the whole should place him nearly upon a level with Descartes.” This estimate of Locke was (...) not the common opinion in England during the nineteenth century. This opinion was reflected in Fraser’s book which, Peirce remarked, could not “be said to be a sympathetic account of [Locke]. The biographer seems to see no charm in his hero, and is perpetually speaking of his want of imagination; which only means he was not given to unpractical dreaming.” Locke had his knowledgeable critics and defenders—for instance Dugald Stewart and John Stuart Mill—but the common opinion ranged from extreme hostility and contempt to condescending criticism of isolated minor points. His style was deplored, his philosophy was called unoriginal and a mere unacknowledged plagiarism of Gassendi and Hobbes; he was said to have so thoroughly misunderstood Descartes that he had merely repeated him with new errors; he was said to owe his philosophical reputation entirely to his advocacy of the popular argument for political freedom or merely to the intellectual circumstances of his time; he was held accountable for Condillac’s rejection of reflection and reason; he was knocked down with a few bare sentences loosely drawn from Leibniz; he was said to have made the mind a puny, passive, mechanical thing. He was called a sensualist, a materialist, a sceptic, an atheist, and a utilitarian though at the same time—and not without contradiction—he was generally, especially by his critics, styled a “great lover of truth,” a plain and simple, well-meaning and religious man. To the nineteenth century Locke meant the Essay, and the history of the Essay was in large measure the history of modern thought, of the eighteenth century. Precisely for this reason there was something nearly sinister about him, in spite of his good personal character. “Locke, himself a clear, humble-minded, patient, reverent, nay, religious man,” said Carlyle, “had paved the way for banishing religion from the world.”.

Written in the 1960s, TRUTH AND METHOD is Gadamer's magnum opus. Looking behind the self-consciousness of science, he discusses the tense relationship between truth and methodology. In examining the different experiences of truth, he aims to "present the hermeneutic phenomenon in its fullest extent.

This essay argues that Pufendorf conceived the principles of natural law against the rationalism and innatism of the 17th century, and that Condillac similarly formulated a conception of the human origin of language, both of them thus securing open and human foundations for the two primal institutions of law and language, and also making all citizens free agents in the ordering of communal living.

O objetivo do presente artigo é tornar explicíta a tese jonasiana segundo a qual matéria e espírito, mente e corpo expressam duas dimensões irredutíveis do ser como um todo.

Desautorizar a tese do monismo materialista é tão importante para a ética da responsabilidade como foi para Jonas criticar o (...) dualismo cartesiano, contra o qual ele elaborou sua biologia filosófica.

Introduces contemporary American philosophy of technology through six of its leading figures. The six American philosophers of technology whose work is profiled in this clear and concise introduction to the field—Albert Borgmann, Hubert Dreyfus, Andrew Feenberg, Donna Haraway, Don Ihde, and Langdon Winner—represent a new, empirical direction in the philosophical study of technology that has developed mainly in North America. In place of the grand philosophical schemes of the classical generation of European philosophers of technology, the contemporary American generation addresses (...) concrete technological practices and the co-evolution of technology and society in modern culture. Six Dutch philosophers associated with Twente University survey and critique the full scope and development of their American colleagues’ work, often illustrating shifts from earlier to more recent interests. Individual chapters focus on Borgmann’s engagement with technology and everyday life; Dreyfus’s work on the limits of artificial intelligence; Feenberg’s perspectives on the cultural and social possibilities opened by technologies; Haraway’s conception of the cyborg and its attendant blurring of boundaries; Ihde’s explorations of the place of technology in the lifeworld; and Winner’s fascination with the moral and political implications of modern technologies. American Philosophy of Technology offers an insightful and readable introduction to this new and distinctly American philosophical turn. Contributors are Hans Achterhuis, Philip Brey, René Munnik, Martijntje Smits, Pieter Tijmes, and Peter-Paul Verbeek. (shrink)

Hans Reichenbach, a philosopher of science who was one of five students in Einstein's first seminar on the general theory of relativity, became Einstein's bulldog, defending the theory against criticism from philosophers, physicists, and popular commentators. This book chronicles the development of Reichenbach's reconstruction of Einstein's theory in a way that clearly sets out all of its philosophical commitments and its physical predictions as well as the battles that Reichenbach fought on its behalf, in both the academic and popular (...) press. The essays include reviews and responses to philosophical colleagues, such as Moritz Schlick and Hugo Dingler; polemical discussions with physicists Max Born and D. C. Miller; as well as popular articles meant to clarify aspects of Einstein's theories and set out their philosophical ramifications for the layperson. At a time when physics and philosophy were both undergoing revolutionary changes in content and method, this book is a window into the development of scientific philosophy and the role of the philosopher.

Radical democratic thinking is becoming intrigued by the material situatedness of its political agents and by the role of nonhuman participants in political interaction. At stake here is the displacement of narrow anthropocentrism that currently guides democratic theory and practice, and its repositioning into what we call ‘the nonhuman condition’. This Critical Exchange explores the nonhuman condition. It asks: What are the implications of decentering the human subject via a new materialist reading of radical democracy? Does this reading dilute political (...) agency? Or should this be seen, on the contrary, as an invitation for new voices and demands to enter into democratic assemblages? How might engagement with the more-than-human disrupt or extend theories of radical democracy? Hans Asenbaum and Amanda Machin discuss the human democratic subject both through radical democratic and new materialist lenses. They suggest that a new materialist decentred subject does not lose agency but further gains political responsibility in radical democracy. Jean-Paul Gagnon highlights the possibility of becoming through loss. In losing our anthropocentric arrogance—our understanding of being other and better than animal—we become more connected and discover our place in human-nonhuman assemblages. Melissa Orlie agrees that something can be gained through renouncing dominant human fantasies and presents a ‘radical democratic naturalism’. By renouncing land violence and acknowledging nature’s subjectivity, we can further nonexploitative radical democratic politics. This is where the notion of ‘tidalectic’ processes introduced by James L. Smith is helpful. Focusing on water and the Indigenous knowledges around rivers, he considers how democracy and community can be reimagined as plural, cyclical and attentive to the nonhuman with which the human is inevitably entangled. Diana Leong offers a different approach. Considering the nonhuman from the perspective of Black Studies demands an awareness to how blackness has long been constituted as non- or partially human.

Current radical democratic politics is characterized by new participatory spaces for citizens’ engagement, which aim at facilitating the democratic ideals of freedom and equality. These spaces are, however, situated in the context of deep societal inequalities. Modes of discrimination are carried over into participatory interaction. The democratic subject is judged by its physically embodied appearance, which replicates external hierarchies and impedes the freedom of self-expression. To tackle this problem, this article seeks to identify ways to increase the freedom of the (...) subject to explore its multiple self. Understanding the self as inherently fugitive, the article investigates participatory, deliberative and agonistic concepts of self-transformation. As all of them appear limited, it introduces a transformative perspective in democratic thought. Enriching the transformative perspective with queer and gender theory, the article generates the concept of a politics of becoming, which, through radical democratic practices of disidentification, advances the freedom of the subject to change.

In this book Han Thomas Adriaenssen offers the first comparative exploration of the sceptical reception of representationalism in medieval and early modern philosophy. Descartes is traditionally credited with inaugurating a new kind of scepticism by saying that the direct objects of perception are images in the mind, not external objects, but Adriaenssen shows that as early as the thirteenth century, critics had already found similar problems in Aquinas's theory of representation. He charts the attempts of philosophers in both periods to (...) grapple with these problems, and shows how in order to address the challenges of scepticism and representation, modern philosophers in the wake of Descartes often breathed new life into old ideas, remoulding them in ways that we are just beginning to understand. His book will be valuable for historians interested in the medieval background to early modern thought, and to medievalists looking at continuity with the early modern period. -/- . (shrink)

History, Metaphors, Fables allows readers to discover a master thinker whose role in the German intellectual post-war scene can hardly be overestimated. (shrink)

although mostly known to specialists nowadays, Kenelm Digby was a remarkable figure on the intellectual scene of the early seventeenth century. He has been described as “one of the most influential natural philosophers” of his time,1 and corresponded with many of the great scholars of his days, including Descartes, and the French pioneer of atomism, Pierre Gassendi. In the later years of his life, Digby, alongside men like Robert Boyle, became one of the founding members of the Royal Society.2Digby authored (...) one major work of philosophy: the Two Treatises of 1644.

This paper looks at the critical reception of two central claims of Peter Auriol’s theory of cognition: the claim that the objects of cognition have an apparent or objective being that resists reduction to the real being of objects, and the claim that there may be natural intuitive cognitions of nonexistent objects. These claims earned Auriol the criticism of his fellow Franciscans, Walter Chatton and Adam Wodeham. According to them, the theory of apparent being was what had led Auriol to (...) allow for intuitive cognitions of nonexistents, but the intuitive cognition of nonexistents, at its turn, led to scepticism. Modern commentators have offered similar readings of Auriol, but this paper argues, first, that the apparent being provides no special reason to think there could be intuitions of nonexistent objects, and second, that despite his idiosyncratic account of intuition, Auriol was no more vulnerable to scepticism than his critics.

In response to its current crisis, scholars call for the revitalisation of democracy through democratic innovations. While they make ample use of life metaphors describing democracy as a living organism, no comprehensive understanding of ‘life’ has been established within democratic theory. The Black Lives Matter (BLM) movement articulates the urgency of refocusing on life and its meaning through radical democratic practice. This article employs a grounded theory approach, enriched with participatory methods, to develop a radical democratic concept of life in (...) conversation with BLM. It conceptualises life as the existence of a perspective that constantly transforms through its fundamental interconnectedness. Building on this concept, the article outlines four principles of a living democracy that go beyond the revitalisation discourse. A living democracy (1) safeguards the existence of all humans and nonhumans, (2) nurtures a diversity of perspectives, (3) fosters social and planetary connectivity, and (4) enables self- and collective transformation.

The work of Thomas White represents a systematic attempt to combine the best of the new science of the seventeenth century with the best of Aristotelian tradition. This attempt earned him the criticism of Hobbes and the praise of Leibniz, but today, most of his attempts to navigate between traditions remain to be explored in detail. This paper does so for his ontology of accidents. It argues that his criticism of accidents in the category of location as entities over and (...) above substances was likely aimed at Francisco Suárez, and shows how White’s worries about the analysis of location were linked with his broader cosmological views. White rejects real qualities, but holds that the quantity of a substance is somehow distinct from its bearer. This reveals a common ground with some of his scholastic interlocutors, but lays bare a deep disagreement with thinkers like Descartes on the nature of matter. (shrink)
