Reliabilist accounts of knowledge are widely seen as having the resources for blocking sceptical arguments, since these arguments appear to rely on assumptions about the nature of knowledge that are rendered illegitimate by reliabilist accounts. The goal of this book is to assess the main arguments against the possibility of knowledge, and its conclusions challenge this consensus. The book articulates and defends a theory of knowledge that belongs firmly in the truth-tracking tradition, and argues that although the theory has the (...) resources for blocking the main standard lines of sceptical reasoning, there is a sceptical argument against which the theory offers no defence, as it doesn’t rely on any assumptions that the theory would render illegitimate. The book ends with the suggestion that the problem might have a metaphysical solution—that although the sceptical argument may make no illegitimate epistemological assumptions, it does rest on a questionable account of the nature of cognition.

In this paper we expand previous results obtained in [2] about the study of categorical equivalence between the category IRL 0 of integral residuated lattices with bottom, which generalize MV-algebras and a category whose objects are called c-differential residuated lattices. The equivalence is given by a functor ${{\mathsf{K}^\bullet}}$ , motivated by an old construction due to J. Kalman, which was studied by Cignoli in [3] in the context of Heyting and Nelson algebras. These results are then specialized to the case (...) of MV-algebras and the corresponding category ${MV^{\bullet}}$ of monadic MV-algebras induced by “Kalman’s functor” ${\mathsf{K}^\bullet}$ . Moreover, we extend the construction to ℓ-groups introducing the new category of monadic ℓ-groups together with a functor ${\Gamma ^\sharp}$ , that is “parallel” to the well known functor ${\Gamma}$ between ℓ and MV-algebras.

This paper argues that narrative elements from the science fiction (SF) literary genre are used in the discourse of Nanoscience and Technology (NST) to bridge the gap between what is technically possible today and its inflated promises for the future. The argument is illustrated through a detailed discussion of two NST texts. The paper concludes by arguing that the use of SF narrative techniques poses serious problems to the development of a critical analysis of the ethical and social implications of (...) NST. (shrink)

The author challenges the view that birth cannot be a morally relevant fact in the process of development from zygote to child. He reviews specific arguments against giving any moral significance to the fact of birth. Drawing on recent work in developmental psychology, he contends that the lives of neonates can have a level of self-consciousness that confers moral significance but can only be possessed after birth. He shows that the position he has argued for provides a framework within which (...) the move from the moral validity of aborting sentient fetuses to the moral validity of infanticide might be resisted. He concludes that arguments suggesting that birth can be morally significant support the view that the acquisition of moral significance is a gradual and multilayered phenomenon. (shrink)

This paper considers how best an eliminativist might argue for the radical falsity of commonsense psychology. I will be arguing that Paul Churchland’s “official” arguments for eliminative materialism (in, e.g., Churchland 1981) are unsatisfactory, although much of the paper will be developing themes that are clearly present in Churchland’s writings. The eliminativist needs to argue that the representations that feed into action are fundamentally different from those invoked by propositional attitude psychology. The “springs of action” are representations of features that (...) are much more finely grained than those encoded within the vocabulary that we employ to specify the content of propositional attitudes. The eliminativist’s most promising strategy is to argue that, whatever we might think about why we behave the way we do, careful experimental work will show that we are in fact acting in virtue of representations of properties and microfeatures that fall completely outside the ambit of propositional attitude psychology. The paper considers a number of examples of how this eliminativist strategy might be developed, ranging from the implications of the two visual systems hypothesis to research in social psychology into the role that situational factors play in controlling action.

Beyond different starting points, stakeholder theory and Catholic Social Thought share many compatible perspectives when analyzing the role of the firm in economic activity, especially regarding the attention of the firm to different social and economic actors. Additionally, ST bears limitations regarding its ethical and anthropological foundation, and also about the legitimation of the different stakeholders’ interests. Therefore, ST lacks clear criteria to solve possible conflicts of interest between stakeholders. This paper analyzes the potentiality of ST, widely accepted in corporate (...) management, to integrate CST principles in order to solve those conflicts. At the same time, the paper studies the possibility of finding in the principles of CST an anthropological and ethical foundation for ST. This foundation could be the source of criteria to discuss the levels of legitimation and prioritization between stakeholders´ interests, especially when those interests collide. (shrink)

The publication of scientific papers has become increasingly problematic in the last decades. Even if we agree that a renewed model is needed for peer-reviewed scientific publication, we think the problem does not essentially lie in professional publishing—with economic incentives—but in the publish-or-perish culture that dominates the lives of researchers and academics.

This article discusses two coextensive concepts of logical consequence that are implicit in the two fundamental logical practices of establishing validity and invalidity for premise-conclusion arguments. The premises and conclusion of an argument have information content (they ?say? something), and they have subject matter (they are ?about? something). The asymmetry between establishing validity and establishing invalidity has long been noted: validity is established through an information-processing procedure exhibiting a step-by-step deduction of the conclusion from the premise-set. Invalidity is established by (...) exhibiting a countermodel satisfying the premises but not the conclusion. The process of establishing validity focuses on information content; the process of establishing invalidity focuses on subject matter. Corcoran's information-theoretic concept of logical consequence corresponds to the former. Tarski's model-theoretic concept of logical consequence formulated in his famous 1936 no-countermodels definition corresponds to the latter. Both are found to be indispensable for understanding the rationale of the deductive method and each complements the other. This study discusses the ontic question of the nature of logical consequence and the epistemic question of the human capabilities presupposed by practical applications of these two concepts as they make validity and invalidity accessible to human knowledge.

In this paper we study collective identity functions that deal with formation of clubs. Usually the choice offered to individuals is to cast a vote in favor of qualification or not, and the final outcome is qualification or non-qualification. In this context we show that independent collective identity functions are naturally characterized by voting rules, and in particular, consent rules can be represented by one single collection of weighted majorities. In addition, we consider the extended model where voters are allowed (...) to abstain and we distinguish between disqualification and a neutral outcome. We show that this environment allows agents to act in different capacities that cannot be distinguished in the original formulation of the problem. (shrink)

This book investigates modern global civilization, offering an alternative to post-colonial theories and the "multiple modernities" approach (as well as the civilizational theory linked to it). It argues that modernity has become a global civilization that is heterogeneous and intertwined with other civilizations, and also aims at a renewal of critical theory that is not US-centric and Eurocentric, focusing instead on China, South Asia (India) and Latin America (Brazil). Dealing with the themes of centre-periphery relations, complexity (including culture and religion), (...) democracy and emancipatory possibilities, this book is based on general theoretical ideas such as collective subjectivity, the interplay of memory and creativity, and the concept of "modernizing moves," so as to deal with historical contingency.

El artículo ana liza ciertas tensiones internas en la filosofía del arte de Danto, derivadas de una tensión originaria, la que se da entre esencialismo eternizante e historicismo. Analiza después la definición del arte que ofrece Danto, interpretando que es una definición poco específica, a falta de una mayor caracterización del símbolo artístico. Concluye con la consideración de la tesis de los indiscernibles perceptivos, y el problema que plantea en relación con una de las dos condiciones esenciales del arte, la (...) de la "encarnación del significado", problema que se mantiene a la hora de pensar la belleza artística.

Muitos termos possuem um sentido técnico sem que ele seja evidente para todos, por exemplo, a "governança ambiental", termo que remete no contexto atual a uma participação cidadã nesse tipo de questão, por exemplo, da saúde de um ecossistema específico, tal como uma floresta ou um vale agrícola, a partir de preocupações partilhadas e não a partir de uma problemática de controle organizacional. Após ter tornado preciso o que é a expertise e quais são os principais problemas postos pelo recurso (...) à expertise nos contextos da ação cidadã, proponho que as expertises técnicas podem ser postas no mesmo patamar que outros tipos de expertise, referindo principalmente aos saberes comuns, à prática e à experiência concreta, dita "de campo", o que corresponde a uma ampliação. Sugere-se, então, o modelo de fórum híbrido como quadro teórico possível dessa reformulação da concepção de expertise. Many terms have a technical meaning although it is not evident for everyone, for example, the "environmental governance", term that refers in the present context to citizen participation on this type of question, for example, of the health of a specific ecosystem, such as a forest or an agricultural field, from shared preoccupations and not from a problematic of organizational control. After having made precise what is the expertise and what are the main problems posed by the recourse to the expertise in the contexts of citizen action, I propose that technical expertise can be tantamount to other types of expertise, referring mainly to profane knowledge, to the practice and concrete experience called "of field", which corresponds to an enlargement. Then it is suggested the model of an hybrid forum as a possible theoretical frame of this reformulation of the conception of expertise. (shrink)

RESUMO O problema da era do gelo foi o primeiro e, até algumas décadas atrás, o único debate relevante sobre as mudanças climáticas, emergindo como uma discussão da geologia, que não foi capaz de equacioná-lo. Ficou como um mistério que transitou, no século XIX, pela matemática e astronomia e foi objeto de especulações na geofísica e geoquímica sem que uma solução satisfatória fosse encontrada. A resposta básica para a ocorrência das eras do gelo foi dada por Milankovitch, com sua teoria (...) matemática da insolação, na década de 1940. Todavia somente a consolidação da paleoclimatologia, na década de 1970, ofereceu as evidências necessárias para comprová-la. O refinamento desses estudos paleoclimatológicos acabou revelando, todavia, um fenômeno inesperado, a saber, que as transições de estados de equilíbrio no sistema climático aconteceram muito rapidamente no passado. As mudanças climáticas da era do gelo do pleistoceno ocorreram de maneira abrupta e radical, em uma negação do gradualismo. Em consequência, o atual aquecimento global deve ser visto como um fenômeno muito mais perigoso e imprevisível do que usualmente apresentado. ABSTRACT The ice age problem was the first and, until a few decades ago, the only relevant debate on climate change, emerging as a discussion in geology, which was unable to frame it. It remained a mystery in the nineteenth century, being discussed in mathematics and astronomy, and it was a matter of speculation in geophysics and geochemistry without a satisfactory solution. The basic explanation for the occurrence of ice ages was given by Milankovitch, by means of his mathematical theory of insolation in the 1940s. Nevertheless, only the consolidation of paleoclimatology, in the 1970s, provided the necessary evidence to prove it. The refinement of these studies in paleoclimatology, however, brought to light an unexpected phenomenon: the transition between equilibrium state in the climate system took place very quickly in the past. Climate change in the Pleistocene Ice Age was abrupt and radical, contrary to any gradualism. Therefore, the current global warming should be seen as a much more dangerous and unpredictable phenomenon, in comparison with the way it is usually presented. (shrink)

A simple, bivalent semantics is defined for Łukasiewicz’s 4-valued modal logic Łm4. It is shown that according to this semantics, the essential presupposition underlying Łm4 is the following: A is a theorem iff A is true conforming to both the reductionist and possibilist theses defined as follows: rt: the value of modal formulas is equivalent to the value of their respective argument iff A is true, etc.); pt: everything is possible. This presupposition highlights and explains all oddities arising in Łm4.

Las distintas tradiciones sobre la celebración de la Pascua en las primeras comunidades cristianas se fundamentan en las diferentes escuelas teológicas de la Iglesia Primitiva y se concretan principalmente en dos formas diferentes, aquí identificadas como Pascha = Passio y Pascha = Transitus zoith sus propias y diferentes implicaciones cristológicas características. A partir del estudio pormenorizado de fuentes hispánicas de los siglos IV al VI, patrísticas, conciliares y litúrgicas, el autor localiza un filón en la tradición de las iglesias de (...) la Península Ibérica que identifica la fiesta de la Pascua con la fiesta de la Pascua. Península Ibérica que identifica la fiesta de Pascua zuitli la pasión de Cristo, como hacía la escuela asiática, y le confiere, sobre todo en la lex orandi, una fuerte intensidad dramática. El artículo pone de relieve una cristología pascual con luz propia y al mismo tiempo revela una mens teológica, bien equilibrada y claramente definida. Las comunidades cristianas de Hispania se beneficiarán de una sana ósmosis entre lex credendi y lex orandi, que les permitirá enfrentarse al arrianismo y llevar a su plena madurez los frutos de la creencia cristiana. En la elaboración de estas tradiciones están profundamente arraigadas muchas de las ideas teológicas y litúrgicas que prevalecen en la Iglesia actual. (shrink)

En el debate entre contextualistas y anticontextualistas, señala Recanati, los últimos aventajan a los primeros por un argumento atribuible a Grice. Este argumento tiene corno premisa el Principio del Paralelismo que, según Recanati, convierte al argumento en circular y a la posición anticontextualista en injustificada. Si bien considero este argumento anticontextualista inadecuado, demostraré que no es atribuible a Grice. Grice no puede admitir el Principio del Paralelismo si se tiene en cuenta la explicación que elabora para ciertos ejemplos y su (...) teoria de las implicaturas. Grice, según esa explicación y algunas de sus propuestas, se muestra como un contextualista. (shrink)

Partindo do pressuposto de que a teoria social elaborada por Habermas em muito se assemelha àquela construída por M. Weber, procedeu-se a um estudo comparativo com a intenção de identificar as formas pelas quais Weber e Habermas elaboraram o conceito de compreensão, ao mesmo tempo em que e o elegeram, cada um a seu modo, como instrumento metodológico adequado às dificuldades da produção de conhecimento científico nas Ciências Sociais. Tanto para Weber, como para Habermas, o conhecimento nas Ciências Sociais não (...) consegue escapar das influências diretas da subjetividade do cientista, como também não é capaz de se proteger das contingências histórico-culturais aos quais inevitavelmente toda ação humana está vinculada. Por isso, fundamentados em suas próprias razões, tanto Weber quanto Habermas apontam a compreensão como a forma possível de conhecimento, o que implica a renúncia às pretensões explicativas e à produção de teorias gerais de fundamentação última, que são típicas das ciências convencionais. Assuming that the social theory developed by Habermas is very similar to that constructed by M. Weber, this article performs a comparative study with the intention of identifying the ways in which Weber and Habermas built the concept of understanding. Both authors chose this concept, each in his own way, as a methodological tool appropriate to the difficulties of the production of scientific knowledge in the social sciences. As much for Weber as for Habermas, knowledge in the social sciences cannot escape the direct influences of the subjectivity of the scientist, as it also cannot protect itself from the historical and cultural contingencies to which every human action is inevitably linked. Therefore, based on their own reasons, both Weber and Habermas point to understanding as the possible form of knowledge, which implies the renunciation of the explanatory pretensions and general theories of ultimate foundations typical of the conventional sciences.

This paper is a rejection of parsimonious behaviorism (PB). PB was proposed by Stemmer (2003) to avoid certain problems with radical behaviorism's (RB) appeal to covert behavior to account for mental phenomena. According to Stemmer, covert behavior was not clearly defined and its existence was not supported by empirical evidence. However, overt behavior is not as undefined, nor its existence as empirically unsupported as Stemmer claimed. Nor does PB avoid the problems, as it does not encourage us to seek a (...) definition or empirical evidence that supports this existence. Moreover, Stemmer did not define the entities he accepted as existent (physiological traces), nor did he cite empirical evidence that supported their existence or his proposed interpretation of mental phenomena. Also, his claim that PB is more parsimonious than RB rests on a fallacious acceptance of the existence of physiological traces and a misinterpretation of the explanatory role of physiological events in RB. Finally, Quine's repudiation theory does not avoid the questions of the status, nature, and location of mental entities in identity theories. Such questions are not fundamentally different from those raised by material entities in general. The questions are thus faced by any materialist position, Quine's repudiation theory included.

A filosofia prática de Kant, ou seja, o nuclear da sua ética, juntamente com o "primado da razão prática sobre a especulativa" e a "religião nos limites da simples razão", com seu acento no "mal radical", têm inegáveis afinidades com a - e em certos casos influxo da - tradição cristã. O próprio Kant terá em alguns momentos reconhecido isso mesmo. Segundo o autor do presente texto, subsistem, contudo, inegáveis divergências. O artigo, escrito a partir de uma declarada 'simpatia metódica, (...) pretende precisar no possível o alcance de umas e de outras, fazendo sobre o tema um balanço positivo. O autor propõe ainda uma hipótese de leitura do Opus Postumum, reconhecendo aqui uma tentativa por parte de Kant no sentido de purificar o seu "teísmo moral" numa direcção que tão pouco é alheia a importantes intuições cristãs. /// Aim of the article is to show that the practical philosophy of Kant, or, in other terms, the core of his ethics, as is the case with the "primacy of the practical reason over the speculative one" and the "religion within the limits of pure reason", with its accent set upon the idea of "radical evil", have undeniable affinities with -and in certain cases influxes from - the Christian tradition. Kant himself seems to have recognized that much at certain moments. For the author of the article, however, there are a few divergences to be reckoned with. In fact, the article, which is clearly written from the standpoint of a declared methodic sympathy, does whatever is possible in order to determine the reach of the ones and of the others, but in the end concludes that the result is a positive one. The author also suggests a reading hypothesis for the Opus Postumum, acknowledging here an attempt on the part of Kant directed towards a purification of his "moral theism" in a direction that as such is no less close to some very important Christian intuitions.

Scenarios for the emergence or bootstrap of a lexicon involve the repeated interaction between at least two agents who must reach a consensus on how to name N objects using H words. Here we consider minimal models of two types of learning algorithms: cross-situational learning, in which the individuals determine the meaning of a word by looking for something in common across all observed uses of that word, and supervised operant conditioning learning, in which there is strong feedback between individuals (...) about the intended meaning of the words. Despite the stark differences between these learning schemes, we show that they yield the same communication accuracy in the limits of large N and H , which coincides with the result of the classical occupancy problem of randomly assigning N objects to H words. Key words: lexicon bootstrapping; cross-situational learning; supervised learning; random occupancy problems. (shrink)

Łukasiewicz presented two different analyses of modal notions by means of many-valued logics: the linearly ordered systems Ł3,..., Open image in new window,..., \; the 4-valued logic Ł he defined in the last years of his career. Unfortunately, all these systems contain “Łukasiewicz type paradoxes”. On the other hand, Brady’s 4-valued logic BN4 is the basic 4-valued bilattice logic. The aim of this paper is to show that BN4 can be strengthened with modal operators following Łukasiewicz’s strategy for defining truth-functional (...) modal logics. The systems we define lack “Łukasiewicz type paradoxes”. Following Brady, we endow them with Belnap–Dunn type bivalent semantics. (shrink)

Has the theory of direct reference for general terms ontological consequences or requirements? It has normally been said that general terms should be conceived as rigid designators of “natural classes”, but this is a very vague expression. What is a “natural class” here? Is it a universal? Is it a class of resembling objects or tropes? It is argued that the theory of direct reference functions better in connection with an ontology of universals. The semantic model actually requires certain type (...) of successful cognitive relation with the referent and it is difficult to explain how such a successful connection could be obtained if there are no universal properties, but only perfect resemblance classes of objects or tropes.

Can one reject copyright law and be a qualified observer of its dispositives? This question was taken up by Bertolt Brecht in an intriguing essay concerning the litigation surrounding the film adaptation ofThe Threepenny Opera(1928). Brecht here develops an experimental observation around the nature of film adaptation and cultural production in copyright. While an experimental approach to law was in itself a subversive gesture, the specific legal process enabled him to expose the paradoxical ways in which the copyright system worked.

El pensador norteamericano Richard Rorty sostiene que uno de los deseos de la tradición filosófica occidental ha sido el deseo de la Verdad. Esta premisa asume que la filosofía que arranca con Platón ha establecido las bases para una teoría filosófica de la verdad como correspondencia entre pensamiento y realidad. Como alternativa a la interpretación histórica de Rorty sobre la Verdad, se presenta la noción �clásica� de verdad que forjaron Platón y Aristóteles. Con este análisis se pretende poner de relieve (...) las características del intelecto humano en su relación con la realidad, para distinguir el discurso verdadero del falso. (shrink)
