A editora Losada publicou uma série de conferências de Karl Jaspers pronunciadas na Universidad de laBasilea a convite da Fundação Acadêmica livre e da Faculdade de História da Filosofia daquela Instituição. Esse conjunto de conferências importantes para entender como o filósofo pensava o significado da Filosofia foi reunido em livro com o título de La fe filosófica. O livro integra a coleção da editora argentina denominada Obras Maestras delPensamiento e ainda não teve edição em português. Portanto, La fe filosófica não (...) foi inicialmente concebida como livro, mas como reflexões sobre aspectos fundamentais da Filosofia e mais tarde reunidas numa obra. (shrink)

Taxonomies of living things and the methods used to produce them changed little with the institutionalization of evolutionary thinking in biology. Instead, the relationships expressed in existing taxonomies were merely reinterpreted as the result of evolution, and evolutionary concepts were developed to justify existing methods. I argue that the delay of the Darwinian Revolution in biological taxonomy has resulted partly from a failure to distinguish between two fundamentally different ways of ordering identified by Griffiths : classification and systematization. Classification consists (...) of ordering entities into classes, groups defined by the attributes of their members; in contrast, systematization consists of ordering entities into systems, more inclusive entities whose existence depends on some natural process through which their parts are related. Evolutionary, or phylogenetic, systematics takes evolutionary descent to be the natural process of interest in biological taxonomy. I outline a general framework for a truly phylogenetic systematics and examine some of its consequences. (shrink)

Philosophers and social scientists of diverse orientations have suggested that the pragmatics of semiosis is germane to a dynamic account of meaning as process. Semiosis, the central focus of C. S. Peirce's pragmatic philosophy, may hold a key to perennial problems regarding meaning. Indeed, Peirce's thought should be deemed seminal when placed within the cognitive sciences, especially with respect to his concept of the sign. According to Peirce's pragmatic model, semiosis is a triadic, time-bound, context-sensitive, interpreter-dependent, materially extended dynamic process. (...) Semiosis involves inter-relatedness and inter-action between signs, their objects, acts and events in the world, and the semiotic agents who are in the process of making and taking them. (shrink)

In Philosophical Fragments the pseudonymous author Johannes Climacus explored the question: What is required in order to go beyond Socratic recollection of eternal ideas already possessed by the learner? Written as an afterword to this work, Concluding Unscientific Postscript is on one level a philosophical jest, yet on another it is Climacus's characterization of the subjective thinker's relation to the truth of Christianity. At once ironic, humorous, and polemical, this work takes on the "unscientific" form of a mimical-pathetical-dialectical compilation of (...) ideas. Whereas the movement in the earlier pseudonymous writings is away from the aesthetic, the movement in Postscript is away from speculative thought. Kierkegaard intended Postscript to be his concluding work as an author. The subsequent "second authorship" after The Corsair Affair made Postscript the turning point in the entire authorship. Part One of the text volume examines the truth of Christianity as an objective issue, Part Two the subjective issue of what is involved for the individual in becoming a Christian, and the volume ends with an addendum in which Kierkegaard acknowledges and explains his relation to the pseudonymous authors and their writings. The second volume contains the scholarly apparatus, including a key to references and selected entries from Kierkegaard's journals and papers. (shrink)

Study of Brahmavidāśiravāda of Mādhava, work on Advaita philosophy.

How should one describe the irreducible relationships in photopoetry observed in intermedial literary photobooks? According to most authors, in literary photobooks, the verbal sign system is linked to the photographic image as a bidirectional interaction, creating a coupled system that can be seen as a new sign system. Mutually modulatory influences link verbal text and photography. But the nature of such influences needs to be explained in detail and with accuracy. What kind of relation are we dealing with? Many authors (...) have tried to explain this phenomenon through several epistemic metaphors. The problem is that these metaphors are rarely subjected to any general theory of meaning. Surprisingly, this is not even mentioned as a problem. In this article, we propose a general semiotic model to describe the irreducible photography-poetry relation, derived from C. S. Peirce’s pragmatic theory of signs, and we also present some preliminary results of the analysis of Quarenta Clics em Curitiba, a photobook by Paulo Leminski and Jack Pires. Our purpose here is to introduce and explore this model to describe the photography-poetry relationship in coupled systems. This relationship is decomposed, in the functional roles occupied by poems and photographs, into a sign-object-interpretant relation. The triadic irreducibility that characterizes semiosis (à la Peirce) is the main property applied to photograph-poetry coupling in Quarenta Clics em Curitiba. (shrink)

Carnival was brought to the New World by Spanish and Portuguese colonizers, and it has been preserved there up to our day, although in the meantime it has almost disappeared from the countries where it originated. One asks oneself if Carnival has kept its original characteristics over the years, or if it instead has been transformed, and if so, how. The ethnological and cultural variety present in Latin America leads us to think that there must have been an evolution over (...) the years, and that Carnival should show some signs of acculturation. It is the examination of these two points that will be the subject of our study. (shrink)

O objetivo deste artigo foi investigar a leitura neopragmatista de Richard Rorty (1931-2007) sobre a concepção de subjetividade em Michel Foucault (1926-1984). Rorty ficou conhecido como um celebre filósofo que se opôs à concepção moderna de sujeito, sobretudo, o excesso de antropocentrismo e cientificismo. Quanto ao filósofo francês Michel Foucault, pode-se constatar no terceiro domínio de sua produção teórica, a presença de uma investigação vigorosa sobre a constituição do sujeito. Inicialmente, percebe-se desde seus primeiros escritos, o papel que exerce o (...) poder e a verdade enquanto mecanismos criadores de subjetividade, impondo aos sujeitos modos de ser e de relacionar-se consigo e com os outros. Todavia, a análise sobre a questão da constituição do sujeito se configura de forma mais delimitada nos cursos Subjetividade e Verdade (1981) e A Hermenêutica do Sujeito (1982). Foucault desenvolve uma investigação sobre a subjetividade a partir das noções de ética, filosofia, espiritualidade, sexualidade, arte de viver e cuidado de si, buscando compreender como o sujeito torna-se assujeitado pelo poder e saber, sugerindo novos modos de subjetividade, diferentes daqueles propostos pelo poder. Entretanto, contrariamente ao que propôs Foucault, o filósofo norte-americano neopragmatista Richard Rorty, conhecido por propor uma filosofia edificante, afirma na obra Contingência, ironia e solidariedade (2007) que as ideias do filósofo francês, embora tentem se desvencilhar da concepção moderna de subjetividade, ainda se mantêm atreladas a ela. Assim, pretende-se explorar os argumentos rortyanos que justificam às objeções a Foucault, e com base na análise de textos específicos de ambos os autores, se busca identificar os argumentos usados por Rorty para acusar Foucault de permanecer no quadro teórico da modernidade.

An examination of the post-Darwinian history of biological taxonomy reveals an implicit assumption that the definitions of taxon names consist of lists of organismal traits. That assumption represents a failure to grant the concept of evolution a central role in taxonomy, and it causes conflicts between traditional methods of defining taxon names and evolutionary concepts of taxa. Phylogenetic definitions of taxon names (de Queiroz and Gauthier 1990) grant the concept of common ancestry a central role in the definitions of (...) taxon names and thus constitute an important step in the development of phylogenetic taxonomy. By treating phylogenetic relationships rather than organismal traits as necessary and sufficient properties, phylogenetic definitions remove conflicts between the definitions of taxon names and evolutionary concepts of taxa. The general method of definition represented by phylogenetic definitions of clade names can be applied to the names of other kinds of composite wholes, including populations and biological species. That the names of individuals (composite wholes) can be defined in terms of necessary and sufficient properties provides the foundation for a synthesis of seemingly incompatible positions held by contemporary individualists and essentialists concerning the nature of taxa and the definitions of taxon names.

Biosemiotics is a growing fi eld that investigates semiotic processes in the living realm in an attempt to combine the fi ndings of the biological sciences and semiotics. Semiotic processes are more or less what biologists have typically referred to as “ signals, ” “ codes, ”and “ information processing ”in biosystems, but these processes are here understood under the more general notion of semiosis, that is, the production, action, and interpretation of signs. Thus, biosemiotics can be seen as biology (...) interpreted as a study of living sign systems — which also means that semiosis or sign process can be seen as the very nature of life itself. In other words, biosemiotics is a field of research investigating semiotic processes (meaning, signification, communication, and habit formation in living systems) and the physicochemical preconditions for sign action and interpretation. -/- (...).

No processo de reconstrução da filosofia, está colocado para John Dewey o desafio da articulação entre filosofia e ciência e, como consequência disso, a mudança no método de operar da primeira. Dewey desenvolveu um programa doutrinário que visa mostrar como o conhecimento se funda na experiência. Essa é a dimensão científico-naturalista da sua obra, cuja influência advém do naturalismo darwinista. Nesse sentido, o seu projeto consiste numa rigorosa argumentação contra as explicações em que a experiência e a natureza são apresentadas (...) com base em distinções arbitrárias. Na obra Reconstruction in Philosophy, Dewey desenvolveu seu projeto metafísico de dimensão historicista, propondo uma reconstrução para a filosofia. Essa perspectiva é de inspiração hegeliana, considerando a história como “fluxo dos acontecimentos”. Sua argumentação consiste em reivindicar uma filosofia da experiência, na medida em que se apropria do método científico. Dewey tenta pensar um sistema desenvolvido a partir da aplicação do método científico à filosofia, mas tendo como base uma concepção filosófica da experiência. As concepções de Dewey acerca do conhecimento, do uso inteligente da razão e da natureza social da filosofia concorrem para a constituição de sua concepção de ciência. O objetivo do filósofo é desenvolver um projeto científico e metodológico que exigirá outra forma de fazer filosofia, que ele caracteriza como uma filosofia empírica. Embora Dewey defenda uma filosofia com uma visada científica, isso não significa que ele subordine a filosofia à ciência. Ocorre que Dewey se opõe à forma pela qual o problema epistemológico foi formulado pela tradição, ou seja, desconsiderando o processo de conexão entre as coisas e entre o conhecedor e as coisas. No presente artigo apresentamos este projeto filosófico denominado por nós de metafísica empírica. Iniciamos, argumentando a partir de Dewey, com a necessidade da constituição e formação de uma mentalidade científica tendo em vista os fins sociais. Esta reivindicação decorre do fato de Dewey considerar que ciência e democracia compartilham não apenas o mesmo padrão de investigação, o “método da inteligência”, mas também as mesmas virtudes morais: uma disposição para questionar, para procurar clareza e evidência, para ouvir e respeitar as opiniões dos outros, para considerar alternativas de forma imparcial, para mudar de ponto de vista em virtude da investigação e da comunicação. Por fim, discutiremos a teoria pragmatista da existência, cujo objetivo é a constituição de uma nova metafísica que consiste em administrar, no domínio temporal, o finito e o humano em sua relação com o eterno e o infinito, ou seja, visa apreender a realidade enquanto produto dos seus condicionantes. Em sua crítica à metafísica tradicional, Dewey deixa subentendido que o que se tem em termos dessas metafísicas não passa de técnicas intelectuais refinadas, derivadas das ideias rudimentares da fé popular acerca do sobrenatural e do natural, do divino e do humano.

O presente artigo é uma crítica à interpretação rortyana de Dewey. Nosso propósito é argumentar que as hipóteses de Rorty sobre o pragmatismo deweyano não podem ser confirmadas. Existem diferenças significativas entre a filosofia de Dewey e o neopragmatismo de Rorty. Nesse sentido, faremos objeções a alguns conceitos que aparecem na apropriação rortyana da filosofia de Dewey, a saber, a ideia do fim da filosofia, o relativismo expresso em sua crítica à ciência e a teoria conversacionalista como substituta da epistemologia. (...) Argumentaremos, especialmente, contra a proposta de Rorty, em que o conceito de linguagem tomaria o lugar do conceito de experiência na obra de Dewey. Assim, apresentaremos a metafísica empírica de Dewey em toda a sua especificidade, mostrando a inadequação da interpretação rortyana, condição que nos ajudará a confirmar o caráter não-rortyano da filosofia de Dewey.: This article is a critique of Rorty interpretation of Dewey. Our purpose is to argue that the hipoteses of Rorty about Dewey's pragmatism can not be confirmed. There are significant differences between the philosophy of Dewey and Rorty's neo-pragmatism. Accordingly, we will object to some concepts that appear in the appropriation of Dewey Rorty's philosophy, namely, the idea of the end of philosophy, relativism expressed in his criticism of the science and theory of epistemology conversacionalista as a substitute. Argue, especially against the proposed Rorty, in which the concept of language would replace the concept of experience in the work of Dewey. Thus, we present empirical metaphysics Dewey in all its specificity, showing the inadequacy of interpretation Rorty, a condition that will help us to confirm a character non-Rorty's philosophy of Dewey.

Xenotransplantation, or the use of animal cells, tissues and organs for humans, has been promoted as an important solution to the worldwide shortage of organs. While scientific studies continue to be done to address problems of rejection and the possibility of animal-to-human virus transfer, socio-ethical and legal questions have also been raised around informed consent, life-long monitoring, animal welfare and animal rights, and appropriate regulatory practices. Many calls have also been made to consult publics before policy decisions are made. This (...) paper describes the Canadian public consultation process on xenotransplantation carried out by the Canadian Public Health Association in an arm’s length process from Health Canada, the ministry overseeing government health policy and regulation. Focusing on six citizen fora conducted around the country patterned after the citizen jury deliberative approach, the paper describes the citizen panelists’ recommendations to hold off on proceeding with clinical trials and the rationales behind this recommendation. The consultation process is discussed in the context of constructive technology assessment, a framework which argues for broader input into earlier stages of technology innovation, particularly at the technology design stage.

The historical reconstruction of the origins of the Neutral Theory of Molecular Evolution (NTME) has been seen purely as an extension of a long-held theoretical debate between the classical and balance schools of Population Genetics. In this perspective, the NTME is but a different interpretation of the then recently published data on high intrapopulation genetic variability. In this paper we try to show that this thesis is deficient and partially incorrect. We show that the sources for the construction and development (...) of the NTME are more varied than this traditional account. We support the Dietrich Historical Thesis, which is the view that different versions of the NTME (Kimura, and King and Jukes) show different kinds of experimental and theoretical support and coincide in recognizing the importance of the then new molecular experimental approach and of its comparative results in evolutionary biology. We stress this case to show the limits of the traditional approach in history and philosophy of science that emphasizes the theoretical activities of scientists and the theoretical characterization of disciplines.

Noël Carroll denies and Robert Stecker affirms that it is a necessary condition of aesthetic experience that it should be valued for its own sake. I make use of their controversy to argue for the psychological impossibility of discharging very common practices of art evaluation and analysis without undergoing an aesthetic experience valued for its own sake. By way of supporting my thesis and also making progress in Stecker and Carroll’s dispute about aesthetic experience, I analyse their methodological assumptions and (...) develop further our understanding of negative, indifferent and unexpected aesthetic experiences. The article provides a defence of Stecker’s position based on my contention regarding art evaluation and analysis. (shrink)

Stem cell tourism is a small but growing part of the thriving global medical tourism marketplace. Much stem cell research remains at the experimental stage, with clinical trials still uncommon. However, there are over 700 clinics estimated to be operating in mostly developing countries – from Costa Rica and Argentina to China, India and Russia – that have lured many patients, mostly from industrialized countries, driven by desperation and hope, which in turn continue to fuel the growth of such tourism.While (...) much research has focused on such dimensions as the promotions that allow such businesses to make their services known, media coverage, some patient research, and regulatory conditions for developing country clinics, little attention has been paid to the non-affected members of the general population, the future potential users of such services. This empirical study based on five focus group discussions with a diverse group of healthy adults in a Canadian city, explored participant views of patients who use stem cell tourism services, the likelihood they would avail themselves of such services if they were to suffer similar illnesses, and the conditions under which they might do so, and the impact that admonitions and advice from international expert bodies might have on their decisions. Our findings suggest that these healthy adults are sympathetic to the drivers of hope and desperation, and, despite cautions about research limitations, may seek such treatments themselves under similar conditions. These findings are discussed in the context of the policy and ethical issues raised by this form of medical tourism. (shrink)

At least three different issues are commonly referred to by the term “the species problem”: one concerns the necessary properties of species, a second the processes responsible for the existence of species, and a third methods for inferring species limits. Solutions have recently been proposed to the first two problems, which are conceptual in nature (the third is methodological). The first equates species with metapopulation lineages and proposes that existence as a separately evolving metapopulation lineage be considered the only necessary (...) property of species. The second views the species category as a cluster concept and proposes that no single process or set of processes be considered necessary for the existence of species. Although these two solutions have been portrayed as being in conflict, they are, in fact, highly compatible. Moreover, the proposals in question clarify the problem concerning methods for inferring the limits of species, which has for a long time been confused with the problem concerning the necessary properties of species. Together these proposals provide the opportunity for biology to move beyond debates about the definition of the species category and focus on estimating the boundaries and numbers of species as well as studying the diverse processes involved in their origin and persistence.

The paper tries to show that an evolutionary perspective helps us to address what is called the adaptation problem, that is, the remarkable coherence, and seemingly successful design, existing between our cognitive tools and the phenomena of the material world. It argues that a fine-grained description of the structure and function of experimental techniques—as a special type amongst evolving scientific practices—is a condition for a better understanding and, ultimately, an explanation of how adaptation among the heterogeneous elements of experimental knowledge (...) is attained. Some apparently contradictory features of techniques, such as their high context-dependency and their capabilities to reproduce and diversify outside their original contexts, are addressed with the help of the concepts of technical variation and the historical entrenchment of phenomena in techniques. In order to do so, a case-study on the construction of satellite-DNA and the evolution of nucleic acid hybridization, a research project carried out by Roy J. Britten and his colleagues in the 1960s, is presented in detail. This case illustrates the close relationship existing between the evolution of techniques and the stabilization of phenomena in experimental biology. (shrink)
