This book is the first complete study of the translations of Machiavelli's Prince made in Europe and the Mediterranean countries during the period from the sixteenth to the first half of the nineteenth century: the first, unpublished French translation by Jacques de Vintimille (1546), the first Latin translation by Silvestro Tegli (1560), as well as the first translations in Dutch (1615), German (1692), Swedish (1757) and Arabic (1824). The first translation produced in Spain - dated somewhere between the end of (...) the sixteenth and the early seventeenth century - remained in manuscript form, while there was a second vernacular Spanish version around 1680. The situation in Great Britain was different from the rest of Europe, as it could boast four manuscript translations by the end of the sixteenth century. (shrink)

In his celebrated historic-epistemological work Identité et réalité, Émile Meyerson claimed that the scientific conservation principles were first suggested and accepted for philosophical reasons, and only afterwards were submitted to experimental tests. One of the instances he discussed in his book is the principle of mass conservation in chemical reactions. Meyerson pointed out that several authors, from Antiquity to Kant, accepted the idea of quantitative conservation of matter; and Lavoisier himself was strongly influenced by a priori ideas, using this principle (...) instead of attempting to test it. This paper will review Meyerson’s claim and historic evidence, focusing especially the late nineteenth and early twentieth century, when the principle of mass conservation was tested in highly accurate experiments. Instead of confirming the principle, some of those experiments led to the detection of anomalies. Hans Landolt, for instance, noticed that there were some small violations of the principle. He observed mass variations of about 10−6 in chemical reactions produced in hermetically sealed glass tubes. Since Landolt was a famous chemist, his results produced a strong response. Several researchers repeated his experiments, with different results. Landolt himself improved his experiments, with a balance that could detect mass changes of 10−7. After changes of the experimental procedure, the chemical reactions did not show significant mass changes. There was not, however, any “crucial experiment” “proving” that mass was conserved. The observed anomalies were set aside mainly by theoretical reasons, after the discovery of radioactivity and the development of the theory of relativity. (shrink)

In the first chapter of the Origin of species and in two chapters of the Variation of animals and plants under domestication, Darwin discusses the origin of domestic pigeons, claiming that all the known breeds were produced from a single species: Columba livia, the rock pigeon. The detailed defense of this point is of high relevance in Darwin’s argumentation strategy, since the differences between the several domestic breeds is so large that, if they were found in the wild, they could (...) be classified as different species or genera. If man was able to produce such large differences, it becomes plausible that nature can produce even larger differences, and therefore the process of natural selection becomes acceptable. Darwin emphasizes the enormous differences between the several domestic breeds (that may have dissimilar cranial structures and a varying number of vertebrae), and at the same time he attempts to show that there are connections and transitions between the extreme types, arguing for their common origin. One of the several interesting parts of his argument is an experiment of crossing between widely different breeds, which led him to obtain pigeons similar to the wild species. The detailed analysis of Darwin’s study of pigeons shows the extreme care he took in his attempt to provide strong arguments for his theory. RESUMO: No primeiro capítulo do Origin of species, e em dois capítulos do Variation of animals and plants under domestication, Darwin discute a origem dos pombos domésticos, defendendo que todas as raças conhecidas provêm de uma única espécie: Columba livia, o pombo de rocha. A defesa detalhada desse ponto é de grande importância na estratégia argumentativa de Darwin, pois as diferenças entre as várias raças de pombos são tão grandes que, se fossem encontradas em estado selvagem, poderiam ser classificadas como espécies ou gêneros diferentes. Se o homem foi capaz de produzir mudanças tão grandes como essas, torna-se plausível que a natureza possa produzir diferenças ainda maiores, e assim o processo de seleção natural se torna aceitável. Darwin enfatiza as grandes diferenças entre as raças de pombos (que chegam a possuir, por exemplo, diferentes estruturas cranianas e diferentes números de vértebras), e ao mesmo tempo procura mostrar a existência de nuances e transições entre os tipos extremos, para defender a origem comum. Um dos aspectos interessantes de sua argumentação é um experimento de cruzamento entre raças bem diferentes, através da qual obtém pombos semelhantes à espécie selvagem. A análise detalhada desse estudo de Darwin mostra o extremo cuidado que ele tomava para tentar proporcionar fortes argumentos a favor de sua teoria. (shrink)

Theory of mind refers to the human capacity for reasoning about others’ mental states based on observations of their actions and unfolding events. This type of reasoning is notorious in the cognitive science literature for its presumed computational intractability. A possible reason could be that it may involve higher-order thinking. To investigate this we formalize theory of mind reasoning as updating of beliefs about beliefs using dynamic epistemic logic, as this formalism allows to parameterize ‘order of thinking.’ We prove that (...) theory of mind reasoning, so formalized, indeed is intractable. Using parameterized complexity we prove, however, that the ‘order parameter’ is not a source of intractability. We furthermore consider a set of alternative parameters and investigate which of them are sources of intractability. We discuss the implications of these results for the understanding of theory of mind. (shrink)

Dialogic Teaching is effective in fostering student learning; yet, it is hard to implement. Little research focused on secondary teachers’ learning of DT and on the link between teachers’ understanding and practices, although these two are usually strongly intertwined. Using a wide range of evidence, this case study systematically investigated and compared two secondary teachers’ understanding and practice of DT during their participation in a continuing professional development programme. The CPDP appeared effective to some extent. The History teacher’s understanding of (...) DT, i.e. being a co-learner, appeared highly effective in implementing DT, whereas the Mathematics teacher’s understanding of DT, i.e. creating a democratic learning environment, seemed only effective to some extent. Focusing on both teachers’ understanding and practice when developing DT seemed fruitful in explaining differences in practice. Future research could further explore to what extent understanding DT as being a co-learner facilitates professional development. (shrink)

Although the few references to the term, Nietzsche's notion of perspectivism is an important assumption of his philosophical reflection. It is a notion, as it will be tried to demonstrate, significant for the understanding of many theoretical positions of the author concerning science and knowledge and decisively for the interpretation of both notions as interpretative perspectives The following argument aims to analyze the influences and assumptions of this notion, highlighting its Kantian (Neokantian), Schopenhaurian background, but also considering influences outside of (...) philosophy, such as Ruggero Boscovich's theoretical physics, which plays a decisive role in the formulation of the notions of perspectivism and perspectivist interpretation in Nietzsche's philosophy.

Direct-to-consumer advertising (DTCA) of prescription drugs has been a heavily contested issue over the past decade, touching on several issues of responsibility facing the pharmaceutical industry. Much research has been conducted on DTCA, but hardly any studies have discussed this topic from a corporate social responsibility (CSR) perspective. In this article, we use several elements of CSR, emphasising consumer autonomy and safety, to analyse differences in DTCA practices within two different policy contexts, the United States of America and the European (...) Union (EU). Doing so results in an alternative analysis of the struggle between proponents and opponents of DTCA from a CSR perspective, adding an alternative view on this debate. (shrink)

Este trabajo analiza las diferencias entre las teorías de Lorentz y Poincaré (quienes aceptaban el éter) y de Einstein, cuestionando las explicaciones comunes de los motivos por los cuales la teoría de la relatividad es preferible a la anterior. La principal diferencia entre los puntos de vista de Einstein y de Lorentz y Poincaré era de naturaleza epistemológica y no teórica. Cada uno de los enfoques tenía aspectos epistémicos positivos, pero de la misma manera les hacía falta a los dos (...) puntos de vista determinados aspectos que estaban presentes en la otra propuesta. Por lo tanto, una de ellas no era superior a la otra. De ese modo, no había argumentos conclusivos que permitieron elegir una de ellas y rechazar a la otra. (shrink)

Este trabajo discute si hoy todavía es posible admitir que hay principios a priori que no pueden ser abandonados por la física. La historia indica que ciertas “imposibilidades” filosóficas (como el movimiento, el vacuo y la acción directa a distancia) fueron sucesivamente abandonadas por la física. En el siglo XX, la mecánica cuántica rechazó al determinismo y al principio de simetría. La opinión más común entre los científicos es la de que cuando hay un conflicto entre física y filosofía hay (...) que despreciar a los principios a priori. Sin embargo, hay todavía casos en los cuales es posible negar la posibilidad de determinados objetos físicos que entran en conflicto con nuestros conceptos espaciales. El autor defiende que existen principios a priori válidos en la física, y que su abandono es una deficiencia de determinadas teorías físicas modernas. Tal postura no tiene por consecuencia la negación de tales teorías, pero impone la tarea de complementarlas o interpretarlas de un novo modo para que sean compatibles con los principios filosóficos.

Norwood Hanson's last paper (“An anatomy of discovery”, 1967) presented an analysis of the very concept of "discovery". Many recent historiographical works discuss episodes of scientific discovery, but there are few epistemological analyses of this concept. The present paper attempts to improve Hanson's work, proposing a hierarchical series of discovery levels. The analysis presented here establishes the conditions that should be satisfied in order to ascribe the scientific discovery of a new phenomenon to somebody. It also points out the partial (...) aims that one should endeavour to attain in the investigation of a new phenomenon. RESUMEN: El último artículo escrito por Norwood Hanson (“An anatomy of discovery”, 1967) analizaba el concepto mismo de “descubrimiento”. Muchos trabajos historiográficos recientes discuten episodios de descubrimientos científicos, pero hay pocos análisis epistemológicos de este concepto. El presente artículo procura perfeccionar el trabajo de Hanson, proponiendo una serie jerárquica de niveles de descubrimiento. El análisis que se presenta acá establece las condiciones que deben ser satisfechas para que se atribuya a un individuo el descubrimiento científico de un novo fenómeno, e indica también las metas parciales que se deben buscar en la investigación de un fenómeno desconocido.

Towards the middle of the 18th century, Pierre-Louis Moreau de Maupertuis proposed the “principle of least action” as a fundamental law of physics and as a proof of the existence of God. Samuel König and other contemporary authors criticized Maupertuis’ work. There ensued a fierce discussion concerning this subject, in which Leonhard Euler, the king Frédéric II of Prussia and Voltaire took part. This paper discusses that debate, emphasizing its extrascientific features and analyzing the interests that motivated the actions of (...) the people involved in that episode. RESUMO: Em meados do século XVIII, Pierre-Louis Moreau de Maupertuis propôs o “princípio de ação mínima”, que seria uma lei fundamental da física, além de constituir uma prova da existência de Deus. O trabalho de Maupertuis foi criticado por Samuel König e outros autores da época. Ocorreu uma violenta discussão a respeito desse assunto, da qual participaram Leonhard Euler, o rei Frédéric II da Prússia e Voltaire. Este artigo estuda o debate ocorrido, enfatizando especialmente os aspectos extracientíficos e analisando os interesses que motivaram as ações das pessoas envolvidas nesse episódio. (shrink)

From Antiquity to the 19th century it was very common to explain natural phenomena (especially biological ones) through final causes. This paper analyses one of the periods of development of this concept, in Antiquity, with special emphasis upon the contributions of Socrates and Plato. They introduced the idea of an intelligent and beneficial god, who plans the structure of the universe and of all beings in the best possible way. This concept was strongly influential in later periods. RESUMO: Da Antiguidade (...) até o século XIX foi muito comum procurar-se entender os fenômenos naturais (especialmente os biológicos) através de causas finais. Este artigo analisa um dos períodos de formação dessas concepções, na Antiguidade, dando especial atenção às contribuições de Sócrates e Platão. Estes introduzem a ideia de uma divindade inteligente e bondosa, que planeja a estrutura do universo e de todos os seres da melhor forma possível. Essa concepção teve grande influência, no período posterior. (shrink)

O conceito de pseudo-ciência procura identificar propostas que têm uma aparência científica mas que não satisfazem critérios rigorosos de cientificidade. Alguns exemplos muito citados de pseudo-fenômenos estão os fatos alegados pela parapsicologia e pela astrologia. Para caracterizar a pseudo-ciência alguns autores propuseram critérios psicológicos, sociológicos ou metodológicos. O objetivo básico de uma caracterização metodológica dos pseudo-fenômenos é permitir identificar aquilo que parece existir, mas não existe. Trata-se, portanto, de uma distinção essencialmente ontológica. Este trabalho irá descrever várias tentativas de estabelecer (...) critérios desse tipo e mostrará que nenhuma delas é satisfatória. Será apresentada uma abordagem alternativa, compatível com o caráter provisório do conhecimento científico, que permite avaliar a proposta de existência de um novo fenômeno e guiar a pesquisa, sem no entanto permitir concluir se o fenômeno existe ou não.

This paper describes the four causes accepted by Aristotle, and then focus upon his concept of final causes, especially emphasizing its use in the study of living beings. The article discusses several difficulties in interpreting Aristotle’s teleology, such as its relation with the concept of a providential god, and the difficulty of understanding goals in processes that do not include intelligent agency. The Aristotelian ideas on final causes are highly complex, and they are widely different from those usually ascribed to (...) the philosopher. RESUMO: Este artigo apresenta uma descrição dos quatro tipos de causas aceitas por Aristóteles, centralizando-se depois nas causas finais, focalizando principalmente seu uso no estudo dos seres vivos. Discute diversos problemas da interpretação da teleologia de Aristóteles, tal como sua relação com a ideia de um deus previdente e as dificuldades de compreensão de finalidades em processos que não envolvem agentes inteligentes. As ideias aristotélicas sobre as causas finais são altamente complexas, e muito diferentes das versões simplistas que costumam ser atribuídas ao filósofo. (shrink)

There are several kinds of studies about science (metascientific): empirical studies (grounded upon historical, sociological and other factual data); formal studies (analytic studies, that is, grounded upon logical analysis, definitions, formal distinctions); and axiological studies (grounded on value analysis). Those approaches are epistemologically independent from each other, in the sense that from one of them it is impossible to draw conclusions pertaining to the others. Every normative proposal concerning science is essentially axiological, because it is associated to value judgments (what (...) is valid or invalid in science), and it is impossible to justify norms from empirical or analytical studies. It is important, therefore, to avoid confounding those three approaches, or passing from one of them to another without due notice, because this would lead to epistemological error. In order to emphasize those distinctions, the paper proposes the names "science of science" to describe empirical studies, "scientific methodology" for axiological studies on science that are grounded on internal values, and "analytical epistemology" to refer to formal studies, that merely offer coherent alternative descriptions of science. RESUMO: Os estudos sobre o conhecimento científico (metacientíficos) podem ser de vários tipos: empíricos (baseados em dados históricos, sociológicos, etc.), formais (analíticos, ou seja, baseados em análise lógica, definições e distinções formais) e axiológicos (baseados em análise de valores). Essas três formas de abordagem são epistemologicamente independentes, no sentido de que uma delas não permite tirar conclusões sobre as outras. Toda proposta normativa sobre a ciência é essencialmente axiológica, por estar associada a juízos de valores sobre o que é válido ou não na ciência, e não se pode justificar normas a partir de estudos empíricos ou a partir de estudos analíticos. É importante, por isso, não confundir os três tipos de abordagem, nem tentar passar inconscientemente de uma para outra, pois isso levaria a falhas epistemológicas graves. Para enfatizar essas distinções, o artigo propõe os nomes "ciência da ciência" para os estudos de base empírica, "metodologia científica" para os estudos axiológicos sobre a ciência, baseados em valores internos, e "epistemologia analítica" para estudos formais, que estabeleçam meras alternativas coerentes para a descrição da ciência.

In the early 20th century, science was supposed to be “value free”. In 1953 Richard Rudner claimed that “the scientist qua scientist makes value judgments”, and later philosophers discussed the relations between science and values. From the 60’s onward Michael Scriven and other authors came to the conclusion that non-moral values (intrinsic or epistemic values) are required to evaluate scientific works. This paper supports this general view. However, it stresses that there are several independent scientific values, corresponding to a multi-dimensional (...) value space, and for this reason it is commonly impossible to compare the scientific worth of two different scientific contributions. Scientific values can be used to guide and to evaluate scientific research. However, the result is not a linear succession of better and better theories, but a proliferation of different theories and hypotheses, each of them fulfilling only a few desiderata. RESUMEN: A principios del siglo XX se suponía que la ciencia era “libre de valores”. En 1953 Richard Rudner concedió que “el científico cómo científico hace juicios de valor”, y filósofos posteriores discutieron las relaciones entre la ciencia y los valores. De los años 60 hacia delante, Michael Scriven y otros autores llegaron a la conclusión que valores no-morales (valores científicos intrínsecos o epistémicos) son requeridos para evaluar trabajos científicos. El presente trabajo utiliza esta perspectiva general. Sin embargo, enfatiza que hay muchos valores científicos independientes, correspondiendo a un espacio multidimensional de valores, y por esta razón es comúnmente imposible comparar los valores científicos de dos contribuciones científicas diversas. Los valores científicos se pueden utilizar para dirigir y para evaluar la investigación científica. Sin embargo, el resultado no es una sucesión linear de teorías mejores y mejores, sino una proliferación de teorías y hipótesis diversas, y cada una de ellas satisfaz solamente algunos desiderata.

The mathematical or theoretical approach to the theory of measurement (opposed to the operational approach) is usually accepted by philosophers, at least in its general lines. Some recent criticimsms against this theory can be answered by qualifying the requirements of the theoretical approach as "desiderata", not as strict impositions or prohibitions. Besides, it is shown that the use of this approach is instrumental in creating mathematically simple quantitative laws and in allowing the development of a "scientific intuition" concerning the relevant (...) phenomena. RESUMO: Os filósofos geralmente aceitam pelo menos as idéias gerais da abordagem matemática ou teórica da teoria da mensuração. Essa abordagem opõe-se ao operacionalismo. Algumas críticas recentes contra a abordagem teórica podem ser respondidas qualificando-se as normas que ela propõe como "desiderata", e não como imposições ou proibições estritas. Além disso, mostra-se que o uso dessa abordagem ajuda a criar leis quantitativas matematicamente simples, e permite o desenvolvimento de um tipo de "intuição científica" sobre os fenômenos relevantes.

Einstein knew and accepted some philosophical ideas similar to Bridgman's operationalism, at the time when he developed the theory of relativity. It is possible to detect the influence of those ideas both in the special and the general theories. Some of the basic steps taken by Einstein were essentially operationalistic: they could not be justified without epistemological principles of that kind. The common opinion is held that the special theory of relativity embodied a complete and coherent operational elucidation of physical (...) magnitudes. This paper, however, points out some instances of physical magnitudes used in special relativity – such as the force that acts upon a moving body, its mass and its temperature – that could not be measured. It is claimed that this shows an early empistemological inconsistency in Einstein's work. RESUMO: Einstein conhecia e aceitava idéias filosóficas aparentadas ao operacionalismo de Bridgman na época em que desenvolvia a teoria da relatividade. Pode-se detectar essa influência nas teorias especial e geral da relatividade. Alguns dos passos básicos de Einstein foram essencialmente operacionalistas. Assim, é comum a opinião que supõe ter sido completamente efetuada, na teoria especial, de modo coerente, a elucidação operacional das grandezas físicas. Neste artigo, porém, apresentam-se exemplos de grandezas físicas utilizadas na relatividade especial – como a força que age sobre um corpo em movimento, sua massa e sua temperatura – que não eram mensuráveis. Isso revela uma inconsistência epistemológica no trabalho inicial de Einstein. (shrink)

This work compares the views of René Descartes and Isaac Newton on the nature of gravitation and the possibility of direct action at a distance. In his early writings, Newton tried to find mechanical explanations of gravitation, but could not find any acceptable model. For that reason he preferred to avoid any mechanical explanation. He admitted that the existence of gravitation could be justified by induction, and used it to explain and to predict several phenomena, although gravitation itself was not (...) explained. Descartes, on the other side, tried to explain gravity and the motion of planets using a mechanical model that accepted the existence of vortices of invisible matter. He criticized authors of his time, such as Roberval, who tried to introduce action at a distance. Descartes argued that this would require that brute matter should be endowed with soul and intelligence. This article analyses the arguments of several authors (before and after Descartes) and concludes that Descartes' criticism of action at a distance is valid. RESUMO: Este trabalho discute as posições de René Descartes e Isaac Newton frente à natureza da gravitação e à possibilidade de ações diretas à distância. Newton procurou inicialmente explicações mecânicas da gravitação, porém, não encontrando nenhum modelo aceitável, preferiu não propor nenhuma explicação. Admitindo que a existência da gravitação era justificada pela indução, ele a utilizou para explicar e prever muitos fenômenos, sem que ela própria fosse, no entanto, explicada. Descartes, por sua vez, tentou explicar a gravidade e os movimentos dos planetas a partir de um modelo mecânico de um vórtice de matéria invisível, criticando duramente autores de sua época que, como Roberval, tentaram introduzir a idéia de ação à distância, pois isso exigiria atribuir-se alma e inteligência à matéria bruta. Estudando os argumentos de vários outros autores anteriores e posteriores a Descartes, o artigo defende a posição de Descartes. (shrink)

This paper addresses the context of emergence, development, and current status of the use of history and philosophy of science in science education in Brazil. After a short overview of the three areas (history of science, philosophy of science, and science education) in Brazil, the paper focuses on the application of this approach to teaching physics, chemistry, and biology at the secondary school level. The first Brazilian researches along this line appeared more consistently in the decade of 1970. From 1980 (...) onwards, the importance of this approach became widely accepted, and the subject became a common theme of dissertations and theses, appearing in conferences and educational journals. Since 1998, the use of history and philosophy of science was included among the government recommendations for secondary school science teaching in Brazil. Nowadays, this is an important line of research in graduate programs on science and mathematics education. However, the actual use of this approach in secondary education is still a desideratum.

The Association of Philosophy and History of Science in the South Cone is a non-profit academic association, founded on May 5th, 2000, in Quilmes, Argentina, at the closing ceremony of the 2nd Meeting of Philosophy and History of Science in the South Cone. The creation of this Association was the result of the interest to deepen and strengthen the exchange between the researchers in Philosophy and History of Science from the countries of the South Cone, from the two first meetings (...) that took place in Porto Alegre and Quilmes onwards. Since then, there have been biennial meetings organized as its responsibility. The main aim of AFHIC is to contribute to a better understanding of science from a philosophical as well as a historical point of view in the Spanish and Portuguese-speaking countries, especially in those which belong to the American South Cone, promoting a space for reflection, exchange, discussion, communication, and dissemination of such an understanding. This volume is - with minor changes - the English version of Fisica: Estudos Filosofi cos e Historicos. It is composed of refereed and, in some cases, opportunely modifi ed contributions made by members of the Association of Philosophy and History of Science in the South Cone, some of them who are unfortunately no longer among us.

: Suppose a scientist discovers a new, unpredicted phenomenon. How can one ascertain the causes, properties and laws of the phenomenon? How can one plan the investigation of the circumstances that affect the phenomenon, and of the effects that the new phenomenon could produce? If the phenomenon is completely unexpected and does not fit any previous theory, it is impossible to provide a theoretical prediction of its likely properties. In the empiricist tradition, therefore, the recommended method was to investigate all (...) possibilities, because in such cases it is impossible to exclude a priori anything. William Stanley Jevons provided a clear criticism of this method. It is impossible to investigate all possibilities, because they are boundless. Is it then impossible to plan the research of unexpected new phenomena? No. Jevons pointed out an alternative. According to Jevons, a scientist confronting a new, unexpected phenomenon, should compare it to other known phenomena to establish analogies. This comparison should allow the researcher to find out one or several known phenomena similar to the new one. This paper will present and discuss Jevons’ proposal in the context of late 19th century methodology of science. Keywords: scientific method; empirical research; analogy; Jevons, William Stanley.

According to Aristotelian physics, there was a fundamental distinction between natural and violent motion. When the cause of the motion was internal to the moving body, that motion was regarded as natural. Violent motion was supposed to have an external efficient cause. It should stop as soon as this external cause ceased its action. The fall of a body was believed to have an internal cause – the very nature of the heavy body – but the motion of a projectile (...) was supposed to be accidental and a violent one, produced by an external agent and maintained by the continuous action of the air around it. Those distinctions disappeared from physics during the 17th century. Descartes and Newton do not address those problems. However, in Galileo’s thought those distinctions were still present, and they did play a relevant role in his physics. Some central arguments presented by Galileo Galilei in the Dialogues concerning the two chief world systems depended on the characterisation of circular motion as “natural”. Considerations concerning natural or violent motion, circular and straight motions, provided a trap that led Galileo astray to ideas that seem extremely odd, from the point of view of classical mechanics. This article shows how Galileo struggled with those Aristotelian concepts when he tried to understand the nature of the motion of falling bodies. (shrink)

The issue concerning the nature of science can be dealt in different ways. The question “What is science?” can receive empirical answers (what has been science, historically?), normative answers (what should be science?) and analytical ones (what could be science?). The two later approaches concern Philosophy. This paper criticises some philosophical attitudes towards science (relativism, dogmatism, scepticism, ecletism). It claims the existence of a well grounded acquired epistemological wisdom, encompassed by “impotence principles” that exhibit some limits of the human thought (...) and point out what science cannot be. On the other side, there are no acceptable science/non-science demarcation criteria. This does not lead necessarily to a relativist or anarchist view, because it is possible to argue for a non-prohibitive axiological concept of science that could evaluate and guide research. RESUMO: A questão da natureza da ciência pode ser respondida sob diferentes pontos de vista. A pergunta “O que é a ciência?” pode receber respostas de tipo empírico (o que tem sido, historicamente, a ciência?), de tipo normativo (o que deveria ser a ciência?) e de tipo analítico (o que poderia ser a ciência?). Apenas esses dois últimos enfoques são pertinentes à Filosofia. Este artigo critica algumas atitudes filosóficas frente à natureza da ciência (relativismo, dogmatismo, ceticismo, ecletismo), defendendo no entanto a existência de pontos bem estabelecidos na Epistemologia, dados por “princípios de impotência” que mostram limites do pensamento humano e que indicam o que a ciência não pode ser. Por outro lado, não há critérios aceitáveis de demarcação entre ciência e não-ciência. Isso não leva necessariamente a uma posição relativista ou anarquista, pois é possível defender uma concepção axiológica não-proibitiva da ciência que permite avaliar e orientar a pesquisa. (shrink)

O objetivo deste artigo é investigar quais são as bases ontológicas da ética do futuro, tendo como leitmotiv o conceito de reciprocidade ou, sendo mais preciso, justamente a sua prescindibilidade no âmbito ético, a qual repercute como necessidade ontológica de fundamentação. Partiremos de uma análise do próprio conceito de “ética do futuro” para, explicitar, na sequência, por que, com Jonas, o futuro se torna objeto ético e como ele exige a prescindibilidade da reciprocidade. A partir daí, pretendemos mostrar que a (...) fundamentação ontológica da ética é o caminho de solução para o problema da ausência de reciprocidade e de que modo ela se constitui como crítica àquilo que Jonas chama de dois dogmas da filosofia: “nenhuma verdade metafísica” e “nenhum caminho do é para o deve” (PR, p. 95). Por isso, finalmente, tentaremos mostrar que é contra esses dogmas que se ergue a proposta jonasiana, fundamentada numa metafísica racional que nada mais é do que uma ontologia biológica. (shrink)

Resumo:A reflexão de Nietzsche acerca do conhecimento é inseparável do contexto positivista das universidades alemães na segunda metade do século XIX.

A considerable part of the 20th century epistemology was devoted to attempts at differentiating science from metaphysics or from non-science. Such demarcations try to establish necessary and sufficient conditions to ascribe the scientific status to a theory. However, all demarcations that were proposed conflict with scientific practice, and no proposal received general acceptance. This article suggests a new kind of approach, in which nothing is prohibited in science, but criteria for evaluating and guiding the scientific research are established through desiderata, (...) that establish sufficient (but not necessary) conditions to ascribe a positive scientific value to any contribution. RESUMO Grande parte da epistemologia do século XX discutiu a questão de diferenciar a ciência da metafísica ou da não-ciência.

Este artigo sugere um novo tipo de abordagem, em que não se proibe nada na ciência, estabelecendo-se no entanto critérios que permitam avaliar e guiar o trabalho científico, através de desiderata, que determinam condições suficientes (mas não necessárias) para que algo tenha um valor científico positivo.

In the introduction to hisAllgemeine Psychopathologie, published in 1913, Karl Jaspers stated that psychology has little value for the psychopathologist because it focuses on all kinds of interesting matters, but not on normal psychic life. In this article we argue that today, in the year 2013, little has changed in this respect. During the past century, normal psychic life has rarely been a topic of research. Clinical psychology has focused primarily on studying three other topics: the mind-body problem, the methodological (...) debate and the psychotherapy debate. Due to this focus, our knowledge in the above-mentioned areas has increased significantly, but the issue raised by Karl Jaspers about normal psychic life has still not been addressed. In this article, we propose that normal psychic life should indeed become the new focus of clinical psychology. We illustrate the importance of this new focus with three examples from clinical psychology: the Global Assessment of Functioning scale, empathy and the emergence of positive psychology during the past decade. We then explore the efficacy of phenomenology for studying this normal psychic life, thereby discovering a useful epistemological basis in Husserl’s systematic phenomenology. Various phenomenological research methods are evaluated in the light of this systematic phenomenology. (shrink)

We extend BDDs for plain propositional logic to the fragment of first order logic, consisting of quantifier free logic with zero, successor and equality. We allow equations with zero and successor in the nodes of a BDD, and call such objects -BDDs. We extend the notion of Ordered BDDs in the presence of zero, successor and equality. -BDDs can be transformed to equivalent Ordered -BDDs by applying a number of rewrite rules until a normal form is reached. All paths in (...) these ordered -BDDs represent satisfiable conjunctions. The major advantage of transforming a formula to an equivalent Ordered -BDD is that on the latter it can be observed in constant time whether the formula is a tautology, a contradiction, or just satisfiable.

This essay is a response to proposals to integrate patient-subjective or idiographic data into future versions of nosologies such as the DSM and the ICD. It argues that a nosology is not a suitable vehicle for disseminating psychopathological-phenomenological research results throughout the field. Drawing on the work of Ludwig Binswanger, it examines, on the basis of four postulates, how he applies the Husserlian concept of intentionality in psychiatry and thus arrives at a psychopathological phenomenology. For each individual postulate, we then (...) look in depth at the implications for the current debate around DSM. The conclusion we come to is that, both because of the objective of phenomenological research and because of the complexity of the kind of information involved in findings based on that research, it is impossible to integrate these findings into a nosology without deviating from either them or the nosology itself.
