ObjectivesThe aims of this research were to compare the levels of physical activity of eHealth users and non-users, to determine the effects of these technologies on motivations, and to establish the relationship that could exist between psychological constructs and physical activity behaviors.MethodsThis cross-sectional study involved 569 adults who responded to an online questionnaire during confinement in France. The questions assessed demographics, usage of eHealth for exercise and physical activity, and behavioral levels. The questionnaire also measured the constructs of Social Cognitive (...) Theory, the Theory of Planned Behavior, and automaticity facets toward eHealth for exercise and physical activity.ResultsParticipants who were users of eHealth for exercise and physical activity presented significantly higher levels of vigorous physical activity and total physical activity per week than non-users. The chi-square test showed significant interactions between psychological constructs toward eHealth and physical activity levels. Self-efficacy was significantly and negatively correlated with walking time per week. Concerning the automaticity facets, efficiency was positive and significantly correlated with vigorous physical activity levels per week. Then, regressions analyses showed that self-efficacy and automaticity efficiency explained 5% of the variance of walking minutes per week and vigorous physical activity per week, respectively.ConclusionThis study has shown that people during confinement looked for ways to stay active through eHealth. However, we must put any technological solution into perspective. The eHealth offers possibilities to stay active, however its benefits and the psychological mechanisms affected by it remains to be demonstrated: eHealth could be adapted to each person and context.

La exterioridad de una cosa o de un estado de cosas configurados por el ser humano no implica para Hegel que esa cosa o ese estado de cosas deban ya por ello ser considerados como formas del espíritu objetivo, mientras que en contrapartida las formas del espíritu absoluto estarían entonces conformadas por contenidos ideales del pensamiento. La diferencia entre espíritu objetivo y espíritu absoluto no radica en la diferencia entre lo que el espíritu humano “hace” y lo que “conoce”. En (...) efecto, las obras de arte, es decir, configuraciones exteriores hechas por el ser humano utilizando, por ejemplo, piedras, metales, colores o sonidos, son para Hegel instancias del espíritu absoluto, mientras que, por su parte, realidades que en cuanto tales no son intuibles, como, por ejemplo, los contratos o la organización estatal, son instancias del espíritu objetivo. Que Hegel considere al arte como una forma del espíritu absoluto pone de manifiesto que, a sus ojos, las cosas que intuimos en el universo son, en rigor, productos del propio sujeto que las conoce. Espontáneamente el sujeto cognoscente piensa que lo que intuye es algo que recibe desde un mundo externo; sostener que el arte es una forma de conocimiento es justamente el modo como Hegel está expresando que lo intuido es en todos los casos un contenido producido por el propio espíritu, que es, por así decirlo, una obra de arte humano. En el arte mismo, sin embargo, la producción de la cosa intuible es insuficiente, dado que el material que el espíritu utiliza para sus configuraciones conserva en mayor o menor medida, según el caso, una determinidad propia que resiste a la determinidad que el espíritu busca conferirle. Por esta razón, las obras de arte se presentan inicialmente como productos arbitrarios. Recién cuando integra sus intuiciones en la actividad de comprensión -actividad cognitiva con la que opera la filosofía- y media con ello completamente la determinidad de los contenidos intuidos, el espíritu configura finalmente un universo que le es propio y específico. El objetivo de mi ponencia es reconstruir desde el marco teórico recién expuesto el sentido y función que Hegel le atribuye al arte en su teoría del conocimiento. (shrink)

Ao analisar a teoria da memória mecânica de Hegel, a maioria dos intérpretes considerou apenas dois aspectos da memorização mecânica: o desaparecimento do significado nas palavras mecânicamente memorizadas ou a internalização totalmente abstrata da mente que as memoriza. No primeiro caso, a interpretação concentrou-se na relação entre o significante e o significado das palavras; no segundo caso, concentrou-se na relação entre o signo linguístico como um todo e a mente. Entretanto, a posição específica da memória mecânica na sistematização das atividades (...) cognitivas de Hegel não se baseia nessas duas relações, mas na relação entre o significado de cada palavra e o significado das outras palavras. Ao memorizar de cor fileiras de palavras que não estão conectadas umas às outras por seus significados, mas apenas pela força da mente que decide memorizá-las juntas, a mente se liberta de qualquer conteúdo dado externamente e sublima a referência linear do conteúdo representacional de cada significado à intuição em sua origem. A atualização do poder da mente de interconectar conteúdos de acordo com as próprias regras lógicas da mente realiza, para Hegel, a transição para o pensamento propriamente dito. (shrink)

Liberados el romanticismo y el idealismo del lastre secular de su vínculo imaginario con la “catástrofe alemana” deviene una vez más posible recurrir a ellos para repensar los problemas teóricos y prácticos del presente y localizar nuevos instrumentos conceptuales para su solución. En este contexto recobran interés numerosos temas que fueron objetos privilegiados de reflexión por parte de los pensadores románticos e idealistas. El romanticismo exaltó la Revolución Francesa como un acontecimiento epocal de reivindicación de los derechos de los individuos (...) contra la opresión de las formas anquilosadas de la religión y la organización estatal. Los pensadores románticos se rebelaron contra el orden burgués en todas sus formas, contra la pauta ubicua de la razón económico-instrumental. Para Kant, lo que es útil e intercambiable no posee dignidad, sino precio. El rechazo romántico de la exhaustiva reducción del mundo a mercancía conduce a la recuperación del valor infinito de la naturaleza, en esa medida, a su “reencantamiento”. En una misma línea, el romanticismo preconiza tendencialmente todos los fenómenos no cuantificables, aquéllos que no permiten ser calculados en términos mercantiles: la corporeidad, el erotismo, la pasión, la imaginación y la fantasía, el arte y la poesía, lo telúrico, la diversidad individual y cultural. El idealismo, por su parte, busca una síntesis entre la concepción ilustrada del mundo material y la visión pre-moderna del mismo. El resultado de esa mediación es la explicitación de las estructuras del propio espíritu humano presentes en su comprensión del mundo, toda vez que para el idealismo el mundo es siempre la teoría de la mente humana sobre el mundo. El pensamiento ilustrado pudo por ello confundir la filosofía de la naturaleza de los idealistas con una visión de lo material viciada de antropomorfismo, más próxima a la mística y a los bestiarios medievales que a las ciencias naturales de la Edad Moderna. El idealismo, por el contrario, encuentra en esta suerte de principio antrópico de toda teoría un factor de liberación moral y política. La toma de conciencia de que es el sujeto el que crea sistemas de sentido y que, por tanto, éstos deben reflejar en sí mismos su origen humano, implica el corolario de que con las teorías –sea cual sea el ámbito de la realidad que ellas busquen explicar– se trata en verdad de dispositivos de ordenamiento para el conocimiento y la acción construidas por la propia subjetividad humana; en esta medida, en su origen no se encuentran datos brutos de un supuesto orden natural que debe, por tanto, ser respetado sacralmente, sino la propia comunidad de sujetos vivientes. Aunque haya dejado tras de sí y olvidado el proceso de mediaciones que le dio origen, aunque se presente, pues, como replegado sobre sí mismo y, en esa medida, como la suma de re-presentaciones de un orden encontrado en el mundo, cada sistema de ideas contiene el conjunto de prácticas subjetivas inferenciales que lo constituyeron y que fueron realizadas por múltiples sujetos en plexos históricos concretos. El idealismo consiste en explicitar a la subjetividad actuando en el objeto y, con ello, en conminar el peligro de la mutación de las teorías en ideologías. El fundamento último de la libertad descansa para el idealismo menos en el orden determinado que funciona como condición de posibilidad del ejercicio de la libertad que en el modo de autoconcepción de la propia subjetividad. A partir del mundo de las autoconcepciones del sujeto –para Hegel se trata del ámbito específico del sujeto que ha devenido por ello mismo absoluto– derivan luego, como sus corolarios prácticos, las formas concretas de ordenamiento social y político. Si bien asume en sí numerosos motivos románticos, el idealismo aspira también a una mediación de esos elementos con las contribuciones teóricas de la Ilustración, con la que guarda entonces una relación menos crítica que el romanticismo. Fruto de este espíritu más ecuménico y menos orientado a la ruptura, defiende una concepción más pacífica de la racionalidad capitalista y el mundo burgués. Hegel reivindica así el rol positivo del mercado con su división social del trabajo y una concepción menos revolucionaria y más reformista de la vida política. El neoliberalismo contemporáneo se concibe a sí mismo como el sistema que resulta naturalmente del principio de la libertad negativa. Una tesis central del idealismo alemán es que para que sea posible el ejercicio de la capacidad de decidirse autónomamente por diferentes metas es necesario el marco efectivo de la libertad positiva. Sin la presencia de un orden racional con poder coercitivo sobre los miembros de la sociedad para regular su conducta, la libertad negativa de esos miembros, a primera vista disminuida y parcialmente cercenada por aquel orden, no es en la práctica posible.

David Hilbert’s early foundational views, especially those corresponding to the 1890s, are analysed here. I consider strong evidence for the fact that Hilbert was a logicist at that time, following upon Dedekind’s footsteps in his understanding of pure mathematics. This insight makes it possible to throw new light on the evolution of Hilbert’s foundational ideas, including his early contributions to the foundations of geometry and the real number system. The context of Dedekind-style logicism makes it possible to offer a new (...) analysis of the emergence of Hilbert’s famous ideas on mathematical existence, now seen as a revision of basic principles of the “naive logic” of sets. At the same time, careful scrutiny of his published and unpublished work around the turn of the century uncovers deep differences between his ideas about consistency proofs before and after 1904. Along the way, we cover topics such as the role of sets and of the dichotomic conception of set theory in Hilbert’s early axiomatics, and offer detailed analyses of Hilbert’s paradox and of his completeness axiom (Vollständigkeitsaxiom).

Die Poesie ist für Hegel die Endform der Kunst, in der die Kunst im Allgemeinen durch die Religion überwunden wird. Die These, dass die Poesie den anderen Künsten, d.h. der Architektur, der Skulptur, der Malerei und der Musik, überlegen ist, spricht von einer besonderen Hierarchisierung und Periodisierung, die Hegel zwischen die verschiedenen Kunstformen einführt. Das Kriterium für diese Hierarchisierung und Periodisierung ist offensichtlich das gleiche, nach dem Hegel die Kunst wiederum als eine der Religion und der Philosophie unterlegene Form betrachtet. (...) Dass die Poesie eine den anderen Künsten überlegene Kunstform ist, ist auf den ersten Blick eine überraschende These; und sie wirkt noch überraschender, wenn man sie durch die These ergänzt, dass die Kunst wiederum durch die Religion und die Philosophie als weitere Phasen eines linearen Prozesses aufgehoben wird. Um was für einen linearen Prozess handelt es sich hier eigentlich? Ein linearer Prozess wohin? Der Prozess, von dem Hegel in diesem Kontext spricht, ist ein Erkenntnisprozess, und zwar ein ziemlich spezifischer Erkenntnisprozess, nämlich Erkenntnis des Absoluten. Die Poesiegattung, die für Hegel die Endphase der Kunst ausmacht, ist das moderne Drama, in dessen Zentrum die Darstellung des Charakters und der Handlungen seiner verschiedenen Gestalten steht. Was hat das alles aber mit dem Absoluten zu tun? Was haben das Drama und seine Subgattungen - der Tragödie, der Komödie, der Satire usw. - mit Religion und Philosophie zu tun? Hegel verbindet außerdem die Kunst mit dem Absoluten als eine Erkenntnisform desselben. Aber in welchem Sinne ist die Kunst Erkenntnis? Ist Kunst nicht eher Darstellung und Ausdruck subjektiver Gefühle und Ideen - und eben nicht ein Erfassen der Realität, eben nicht eine Erkenntnisform der Wirklichkeit? Um den allgemeinen Sinn von Hegels Ästhetik und dadurch die besondere Rolle, die er darin der Poesie zuschreibt, verstehen zu können, ist es unentbehrlich, die oben gestellten Fragen zu beantworten. Ein theoretisches und exegetisches Modell zu liefern, das imstande ist, eine solche Aufgabe zu erfüllen, ist das Ziel dieses Beitrags. (shrink)

Delusions are one of the most classical symptoms described in schizophrenia. However, despite delusions are often emotionally charged, they have been investigated using tasks involving non-affective material, such as the Beads task. In this study we compared 30 patients with schizophrenia experiencing delusions with 32 matched controls in their pattern of responses to two versions of the Beads task within a Bayesian framework. The two versions of the Beads task consisted of one emotional and one neutral, both with ratios of (...) beads of 60:40 and 80:20, considered, respectively, as the “difficult” and “easy” variants of the task. Results indicate that patients showed a greater deviation from the normative model, especially in the 60:40 ratio, suggesting that more inaccurate probability estimations are more likely to occur under uncertainty conditions. Additionally, both patients and controls showed a greater deviation in the emotional version of the task, providing evidence of a reasoning bias modulated by the content of the stimuli. Finally, a positive correlation between patients’ deviation and delusional symptomatology was found. Impairments in the 60:40 ratio with emotional content was related to the amount of disruption in life caused by delusions. These results contribute to the understanding of how cognitive mechanisms interact with characteristics of the task in the context of delusional thinking. These findings might be used to inform improved intervention programs in the domain of inferential reasoning. (shrink)

El presente trabajo propone determinadas aproximaciones iusfilosóficas al discurso jurídico, a partir de los estudios realizados por Walter Benjamin sobre Franz Kafka. La investigación se realiza con las herramientas metodológicas que aportan las “teorías críticas del derecho” y los marcos teóricos que indagan la relación “derecho-literatura”. Los textos, discusiones y apuntes realizados por el pensador alemán permiten movilizar un análisis de determinados tópicos y categorías pertenecientes al espacio jurídico. Las investigaciones que realiza en torno a la figura de Kafka ofrecen (...) insumos para indagar la formación, despliegue y conservación del derecho. Desde la obra kafkiana, Benjamin visibiliza y desarticula los conceptos nodales de justicia, ley, poder y violencia, lo que permite dar cuenta de los mecanismos y dispositivos que hacen posible el sustento mitológico del derecho.

Hegel ofrece dos formas -en su filosofía en último análisis complementarias- de caracterizar al idealismo: La primera es próxima a la concepción habitual de idealismo previa a Kant, a saber: como una posición que considera que aquello que conocemos es una modificación de la propia conciencia. La segunda descansa en la tesis de la nulidad de lo finito; según esto, ?idealista? es la filosofía que considera que lo finito no tiene en cuanto tal realidad; ?realista?, a la inversa, es la (...) filosofía que toma el ser de las cosas determinadas como algo fijo y definitivo. Hegel denomina a este idealismo ?absoluto?.El idealismo absoluto es el modelo teórico que interrelaciona la tesis del carácter intrínsecamente ideal de los objetos de conocimiento y la tesis de que las cosas singulares que constituyen el mundo real surgen como una autodeterminación del ser. La premisa que permite tal vínculo es la tesis defendida por Hegel de que ser y pensar nunca se han separado y que su separación es el resultado de una concepción posterior errónea de la mente humana sobre la naturaleza de su actividad cognitiva. La hipostasiación de la disociación que la forma cognitiva de la representación introduce en la unidad indiferenciada de ser y pensar de la que parte la actividad de conocimiento en el sentimiento y la intuición sensibles es para Hegel la que provoca la ilusión retroactiva de que ambos -ser y pensar, mundo conocido y mente que conoce- se diferencian y contraponen. Por el contrario, desde el momento que la sensación es también ella misma un modo particular de la actividad continua e ininterrumpida del pensamiento, en el itinerario que va de la percepción sensible a la comprensión del objeto no hay para Hegel un punto en donde pueda introducirse una fractura que disuelva la unidad primigenia entre el ser y el pensar. En esta precisa medida, el momento final de la actividad de conocimiento, es decir, la actividad de comprender el mundo, es a un tiempo la singularización de los contenidos universales que constituyen la teoría del sujeto sobre el mundo y la autodeterminación de la unidad ser-pensar de la que parte y en todo momento permanece el sujeto que elabora esa teoría. Arribados al punto de vista del concepto, la dicotomía realismo-idealismo queda develada como un corolario de la autoconcepción representacionalista de la subjetividad cognoscente. Esta concepción define al paradigma general del realismo, el cual incluye para Hegel como el anverso y reverso de un mismo modelo teórico tanto lo que tradicionalmente ha sido entendido como realismo como al idealismo que resulta de una universalización de la idealidad de la conciencia singular, ya sea en la variante propuesta por Berkeley, ya sea en la del idealismo trascendental de Kant. A ojos de Hegel, por el contrario, el idealismo no puede ser sino absoluto, es decir, debe incluir en sí mismo el momento del ser y, con él, la realidad de las cosas que el sujeto conoce: la tarea esencial de la filosofía no consiste para Hegel más que en tomar conciencia de la co-pertenencia y unidad intrínseca de ambos.

This paper aims to outline an analysis and interpretation of the process that led to First-Order Logic and its consolidation as a core system of modern logic. We begin with an historical overview of landmarks along the road to modern logic, and proceed to a philosophical discussion casting doubt on the possibility of a purely rational justification of the actual delimitation of First-Order-Logic. On this basis, we advance the thesis that a certain historical tradition was essential to the emergence of (...) modern logic; this traditional context is analyzed as consisting in some guiding principles and, particularly, a set of exemplares (i.e., paradigmatic instances). Then, we proceed to interpret the historical course of development reviewed in section 1, which can broadly be described as a two-phased movement of expansion and then restriction of the scope of logical theory. We shall try to pinpoint ambivalencies in the process, and the main motives for subsequent changes. Among the latter, one may emphasize the spirit of modern axiomatics, the situation of foundational insecurity in the 1920s, the resulting desire to find systems well-behaved from a proof-theoretical point of view, and the metatheoretical results of the 1930s. Not surprisingly, the mathematical and, more specifically, the foundational context in which Firs-Order-Logic matured will be seen to have played a primary role in its shaping. (shrink)

This edited volume, aimed at both students and researchers in philosophy, mathematics and history of science, highlights leading developments in the overlapping areas of philosophy and the history of modern mathematics. It is a coherent, wide ranging account of how a number of topics in the philosophy of mathematics must be reconsidered in the light of the latest historical research and how a number of historical accounts can be deepened by embracing philosophical questions.

A general introduction to the celebrated foundational crisis, discussing how the characteristic traits of modern mathematics (acceptance of the notion of an “arbitrary” function proposed by Dirichlet; wholehearted acceptance of infinite sets and the higher infinite; a preference “to put thoughts in the place of calculations” and to concentrate on “structures” characterized axiomatically; a reliance on “purely existential” methods of proof) provoked extensive polemics and alternative approaches. Going beyond exclusive concentration on the paradoxes, it also discusses the role of the (...) axiom of Choice, issues of predicativity, and goes on to present the ideas of intuitionism and Hilbert's program. The essay closes with Gödel's contributions and the aftermath. (shrink)

The celebrated “creation” of transfinite set theory by Georg Cantor has been studied in detail by historians of mathematics. However, it has generally been overlooked that his research program cannot be adequately explained as an outgrowth of the mainstream mathematics of his day. We review the main extra-mathematical motivations behind Cantor's very novel research, giving particular attention to a key contribution, the Grundlagen (Foundations of a general theory of sets) of 1883, where those motives are articulated in some detail. Evidence (...) from other publications and correspondence is pulled out to provide clarification and a detailed interpretation of those ideas and their impact upon Cantor's research. Throughout the paper, a special effort is made to place Cantor's scientific undertakings within the context of developments in German science and philosophy at the time (philosophers such as Trendelenburg and Lotze, scientists like Weber, Riemann, Vogt, Haeckel), and to reflect on the German intellectual atmosphere during the nineteenth century.

Wind turbines have been used by many groups of humans for many centuries. Wind turbines have allowed groups of humans to perform many different tasks in the past. However, only a century and a half ago, they began to be used to convert the energy captured from wind into electric energy. Moreover, only approximately twenty-five years ago, we started to introduce on a massive scale the energy generated from wind turbines into the electric networks of most developed countries in the (...) world for regular consumption. According to 2017 statistics, approximately 12 percent of the electric energy consumed in the EU is produced by wind turbines. Despite the fact that wind turbines generally appear quite similar externally—i.e., a three-blade structure, a nacelle, a tower, etc.—if we carefully examine the electric technology used within them, we find quite a wide range of technologies for energy conversion, which is a key issue in wind turbine technology. Hence, this paper adopts a dialectic perspective towards analyzing and understanding why several electric technologies coexist in wind turbine technology. We explain the specific factors that have influenced different wind turbine manufacturers to adopt different electric technologies across the last twenty-five years. We show how their actions and the technological directions that have followed have been mutually codetermined, resulting in a technological evolution that has produced today’s wind turbine variety.

This article rereads Benedict de Spinoza and recent interpretations of him as an epistemic democrat through the prism of contemporary debate on the conditions for deliberation in a democracy. Through a reconstruction of Spinoza's arguments and theories of deliberation and its preconditions, we argue that, for deliberation to produce the benefits Spinoza recognizes, the process must be inclusive, and those deliberating must be both intellectually humble and autonomous. This interpretation is new and diverges from those recently advanced by Justin Steinberg (...) and Sandra Leonie Field. In particular, on our reading, Spinoza's critique of humility does not extend to intellectual humility as it is understood today in political theory. Both autonomy and humility, as epistemologically conceived by political theorists today, can therefore be considered Spinozian civic virtues. (shrink)

Based on experience in marriage counseling and contributions made by philosophy of phenomenology and psychology, we have carried out an in-depth analysis of the forgiveness process in the marriage relationship. Philosophy of phenomenology allows to define the conceptual framework of the marriage relationship and its essential features, which gives the therapist a reference to guide the therapeutical process. The description of the process is enriched with contributions of Psychology and particularly Systemic Family Theories. We have identified a number of steps (...) in the forgiveness process, which can be summarized as the passing from the initial pain, through the recovery of dignity and hope, up to the final consciousness of having reached forgiveness, where the intrapersonal process in the offended spouse is imbricated with the interpersonal relationship with the partner in marriage. This interdisciplinary perspective, bringing together clinical practice, philosophy of phenomenology, and psychology, has proven particularly fruitful: it has allowed us to identify when forgiveness becomes a case of regeneration and strengthening of the bonds of marriage, or on the contrary, the cases in which the problems, together with situations of imbalance or relational pathology progress to a chronic state. Apart from this, we have reflected upon the practical application of this theoretical approach in a therapeutic context with couples that need to pass through the forgiveness process, paying special attention to the risks they may encounter. Finally, we suggest possibilities for further investigations along these interdisciplinary lines of study. (shrink)

Gardeners, poets, lovers, and philosophers are all interested in the redness of roses; but only philosophers wonder how it is that two different roses can share the same property. Are red things red because they resemble each other? Or do they resemble each other because they are red? Since the 1970s philosophers have tended to favour the latter view, and held that a satisfactory account of properties must involve the postulation of either universals or tropes. But Gonzalo Rodriguez-Pereyra revives (...) the dormant alternative theory of resemblance nominalism, showing first that it can withstand the attacks of such eminent opponents as Goodman and Armstrong, and then that there are reasons to prefer it to its rival theories. The clarity and rigour of his arguments will challenge metaphysicians to rethink their views on properties. (shrink)

Published in 1998, the main aim of this book is to use a naturalistic, evolutionary approach to solve some of the most important problems in philosophy. The first two problems come from the philosophy of science: the problem of rationality of science and the problem of truth in science. In presenting the first problem, the author argues that the views of Kuhn and Feyerabend do create a very serious challenge to traditional epistemology, however, if the assumption of individual rationality is (...) abandoned in favour of the author's social concept of rationality, a committed naturalism can account for science as a rational activity. In tackling the second problem of truth, the author shows that a committed evolutionary philosophy does not support realism but leads instead to a thorough evolutionary relativism of scientific knowledge. It is nevertheless possible to use this evolutionary relativism to construct a theory of relative truth. The issue of whether science discovers truth has also been tied to absolutism, that a well formulated theory of relative truth is likely to bring about a profound transformation of the way we think about the field. The author explores the notion of relative truth in the philosophy of science, ethics and aesthetics. (shrink)

This paper defends a conceptualistic version of structuralism as the most convincing way of elaborating a philosophical understanding of structuralism in line with the classical tradition. The argument begins with a revision of the tradition of “conceptual mathematics”, incarnated in key figures of the period 1850 to 1940 like Riemann, Dedekind, Hilbert or Noether, showing how it led to a structuralist methodology. Then the tension between the ‘presuppositionless’ approach of those authors, and the platonism of some recent versions of philosophical (...) structuralism, is presented. In order to resolve this tension, we argue for the idea of ‘logical objects’ as a form of minimalist realism, again in the tradition of classical authors including Peirce and Cassirer, and we introduce the basic tenets of conceptual structuralism. The remainder of the paper is devoted to an open discussion of the assumptions behind conceptual structuralism, and—most importantly—an argument to show how the objectivity of mathematics can be explained from the adopted standpoint. This includes the idea that advanced mathematics builds on hypothetical assumptions (Riemann, Peirce, and others), which is presented and discussed in some detail. Finally, the ensuing notion of objectivity is interpreted as a form of particularly robust intersubjectivity, and it is distinguished from fictional or social ontology. (shrink)

Some philosophers think that Paul Feyerabend is a clown, a great many others think that he is one of the most exciting philosophers of science of this century. For me the truth does not lie somewhere in between, for I am decidedly of the second opinion, an opinion that is becoming general around the world as this century comes to an end and history begins to cast its appraising eye upon the intellectual harvest of our era. A good example of (...) this opinion may be found in the admiration for Feyerabend's philosophy of science expressed by Grover Maxwell in his contribution to this volume. Maxwell, recalling his own intellectual transformation, says also that it was Feyerabend who "confirmed my then incipient suspicions that most of the foundations of currently fashionable philosophy and even a great deal of the methodology to which many scientists pay enthusiastic lip service are based on simple mistake- assumptions whose absurdity becomes obvious once attention is directed at them". And lest the reader thinks, as many still do, that however sharp Feyerabend's attacks upon the philosophical establishment may have been, he does not offer a positive philosophy (a complain made by C.A. Hooker and some of the other contributors), Paul Churchland argues otherwise. (shrink)

¿Qué es una crisis epistemológica?

Dedekind’s methodology, in his classic booklet on the foundations of arithmetic, has been the topic of some debate. While some authors make it closely analogue to Hilbert’s early axiomatics, others emphasize its idiosyncratic features, most importantly the fact that no axioms are stated and its careful deductive structure apparently rests on definitions alone. In particular, the so-called Dedekind “axioms” of arithmetic are presented by him as “characteristic conditions” in the _definition_ of the complex concept of a _simply infinite_ system. Making (...) sense of Dedekind’s method may be dependent on an analysis of the classical model of deductive science, as presented by authors from the eighteenth and early nineteenth centuries. Studying the modern reconstructions of Euclidean geometry, we show that they did not presuppose deductive independence of the axioms from the definitions. Authors like Wolff elaborated a mathematics _based on definitions_, and the Wolffian model of deductive science shows significant coincidences with Dedekind’s method, despite the great differences in content and approach. Wolff had a conception of definitions as _genetic_, which bears some similarities with Kant’s idea of synthetic definitions: they are understood as positing the content of mathematical concepts and introducing thought objects (_Gedankendinge_) that are the objects of mathematics. The emphasis on the spontaneity of the understanding, which can be found in this philosophical tradition, can also be fruitfully related with Dedekind’s idea of the “free creation” of mathematical objects.

Pursuing this further, we present evidence that firms with past (...) legal issues may seek EOA membership as a signal of their intention to be compliant in the future. (shrink)

The paper gives a model of the sentences that express the core of the doctrine of the Trinity. The new elements in the model are: 1) an underlying map between "Divine Person" and "God"-- in place of set- theoretic inclusion, and 2) the notion of a predicable keeping or not keeping phase in a system of kinds. These elements, which are explained in the text, are common in everyday language. The model requires no tampering with the fundamental laws of logic, (...) nor does it require the use of any such difficult metaphysical notions as substance and essence as distinct from person.
