According to a widespread view, Thomas Kuhn’s model of scientific development would relegate rationality to a second plane, openly flirting with irrationalist positions. The intent of this article is to clarify this aspect of his thinking and refute this common interpretation. I begin by analysing the nature of values in Kuhn’s model and how they are connected to rationality. For Kuhn, a theory is chosen rationally when: i) the evaluation is based on values characteristic of science; ii) a theory is (...) considered better the more it manifests these values; and iii) the scientist chooses the best-evaluated theory. The second part of this article deals with the thesis of the variability of values. According to Kuhn, the examples through which epistemic values are presented vary for each person, and for this reason individuals interpret these criteria differently. Consequently, two scientists, using the same values, can come to a rational disagreement over which theory to choose. Finally, I point out the limitations of this notion of rationality for the explanation of consensus formation, and the corresponding demand for a sociological theory that reconnects individual rationality with convergence of opinions.

In the last decades, supervised machine learning has seen the widespread growth of highly complex, non-interpretable models, of which deep neural networks are the most typical representative. Due to their complexity, these models have showed an outstanding performance in a series of tasks, as in image recognition and machine translation. Recently, though, there has been an important discussion over whether those non-interpretable models are able to provide any sort of understanding whatsoever. For some scholars, only interpretable models can provide understanding. (...) More popular, however, is the idea that understanding can come from a careful analysis of the dataset or from the model’s theoretical basis. In this paper, I wish to examine the possible forms of obtaining understanding of such non-interpretable models. Two main strategies for providing understanding are analyzed. The first involves understanding without interpretability, either through external evidence for the model’s inner functioning or through analyzing the data. The second is based on the artificial production of interpretable structures, through three main forms: post hoc models, hybrid models, and quasi-interpretable structures. Finally, I consider some of the conceptual difficulties in the attempt to create explanations for these models, and their implications for understanding. (shrink)

Thomas Kuhn is mostly known for his contributions to the philosophy of science. However, it was chiefly to investigations in philosophy of language that he dedicated the last part of his career. The aim of this paper is to present a systematic view of Kuhn’s main ideas on this subject. I start by describing his theory of concept, in particular what he says about kind terms. Such terms, acquired in blocks that form contrast sets or “taxonomies,” are learned through ostensible (...) definitions. Next, I analyze Kuhn’s concepts of “meaning” and “truth.” Finally, I discuss a second type of kinds terms, not fully investigated by him, which is learned together with scientific laws. Resumo Thomas Kuhn é conhecido principalmente por suas contribuições para a filosofia da ciência. No entanto, foi em grande medida à filosofia da linguagem que ele dedicou a última parte de sua carreira. O objetivo deste artigo é apresentar uma visão sistemática das principais ideias de Kuhn sobre esse assunto. Começo descrevendo sua teoria do conceito, em particular o que ele diz sobre termos para espécie. Tais termos, aprendidos em blocos que formam conjuntos de contraste ou “taxonomias”, são aprendidos através de definições ostensivas. Em seguida, analiso as concepções de Kuhn de “significado” e “verdade”. Finalmente, discuto um segundo tipo de termo para espécies, não totalmente investigado por ele, que é aprendido junto com as leis científicas. (shrink)

The Structure of Scientific Revolutions represented a milestone in the attempt to understand scientific development based on empirical observations. However, in the next decades after the publication of his book, history, psychology, and sociology became increasingly marginal in Kuhn’s discussions. In his last articles, Kuhn even suggested that philosophers should pay less attention to empirical data and focus more on “first principles.” The purpose of this article is, first, to describe this radical transformation in Kuhn’s methodological approach, from his initial (...) naturalism to his later and more strict philosophical stance. Next, I present some of the alleged justifications for explaining this transition, such as his interest in problems more firmly attached to the philosophical tradition and a desire for greater acceptance within this community. Although these factors certainly played a role in explaining Kuhn’s change, I also believe that an important theoretical component exerts a fundamental function in this transition: the idea that scientific development is a kind of evolutionary process, which is better understood through the use of abstract theoretical models, instead of sparse observations of scientific activity.

In The Structure of Scientific Revolutions, Thomas Kuhn resorts to concepts from several disciplines in order to describe the general patterns of scientific development. This blend of disciplines can be explained in part by Kuhn's intellectual path, from physics to history and then to philosophy of science; but it also points to a deeper methodological problem, which is the question of what is the real unity of analysis in his model of science. The primary intention of this article is, thus, (...) to give a solution to this difficulty. The answer, I believe, rests on identifying three fundamental units present in Kuhn's theory of scientific development. They are, respectively, the individual, responsible for producing evidence, spreading information, and choosing theories; the community, a set of scientists investigating a series of phenomena; and the groups, individuals with similar behavior but with looser institutional or social ties — a usually neglected category in Kuhnian literature, but equally fundamental for the final outcome of scientific debates. After investigating these categories in detail, I propose a way of integrating them into a general model for explaining the resolution of scientific controversies. Finally, I try to resolve the apparent conflict among disciplinary vocabularies by offering an account of the function of sociological, psychological, and epistemological concepts for describing controversies, and some of the methodologies appropriate for each of these tasks.

Changes of theories are major events in science. Two main types of questions may be asked about them: i) how do scientists choose new theories?, and ii) how is consensus formed? Generally, philosophers do not distinguish these two questions. Kuhn, on the contrary, offers very different answers to each of these questions. Theory-choice, on the one hand, is explained through the application of epistemic criteria, such as accuracy and consistency; nonetheless, because these values do not prescribe a single choice, consensus (...) formation, on the other hand, is explained through a series of socio-epistemic mechanisms, namely: scientific pedagogy, diffusion and production of knowledge within the community, and restructuring of the scientific field. These mechanisms are the basis of Kuhn’s social epistemology, in that they are not restricted to sociology nor epistemology, encompassing both social interactions and epistemic evaluations of theories. Keywords: Thomas Kuhn, consensus formation, social epistemology. (shrink)

'Pedagogia da tolerância' é o resultado da reunião de uma coletânea de reflexões e diálogos do Professor Paulo Freire, organizados em oito conjuntos de depoimentos, testemunhos, seminários e cartas, que revelam e atualizam, com outras palavras e imagens, a discussão central presente em toda sua obra, especialmente na tríade Pedagogia do oprimido, Pedagogia da esperança e Pedagogia da autonomia - a necessária coerência entre o discurso e a prática, o diálogo como método e suas implicações na transformação social, que (...) o reconhecimento do ato pedagógico como ato político nos obriga.

In his work, Bernard Suits presents and pursues a stated objective: to define ‘game’ or, more precisely, ‘game-playing’. In The Grasshopper: Games, Life and Utopia, the author seeks a definition not as a ‘commitment to the universal fruitfulness of definition construction’, but rather with the idea ‘that some things are definable, and some are not’. This is something he believed could resolve many of the issues surrounding the debate on ‘game’ and ‘play’, such as those with Huizinga (in Homo Ludens) (...) or proposed by the anti-definitionism of Wittgenstein, a philosopher who did not accept that it was possible to define ‘game’. In this article, we will trace Suits’ definitional steps and aim to critique his resolution as a kind of ‘formalism’, as it tended to prioritize rules. Furthermore, notwithstanding the merit of his theoretical endeavor – seen in the attempt to define a social component that is so complex and the target of the most diverse interpretations and misconceptions –, it seems to us that, with his theoretical unifying element (lusory attitude), the author has summoned another problem to the debate, that of ‘subjectivism’, rather than a solution (especially to his formalism), even subjecting himself to comparisons with other conceptions (e.g. Fichte) that are also problematic. This aspect will also be criticized. The attention of this article will shift to these two lines of critique, drawing on an insightful analysis of Malaby’s work at a specific juncture, aiming to delve further into the subject and taking an additional step.

Le pari de cet ouvrage est d'explorer les facettes multiples à travers lesquelles se donne le soi. Parler de soi plutôt que de moi implique une rupture franche avec les philosophies qui placent le sujet humain en position fondatrice. Le soi est encore moins une « chose » mais un mode d'être ; le soi n'est pas une donnée mais une conquête dont le devenir est en partie indéterminé. C'est donc sous le signe des épreuves qu'il faut penser les variations (...) phénoménologiques et herméneutiques sur le soi. Si la philosophie reste la discipline dominante des réflexions qui parcourent les contributions du volume, l'originalité de cet ouvrage est d'offrir en même temps au lecteur d'autres variations par lesquelles se décline le soi.

Plato's Academy is commonly regarded as the most prestigious and most influential of all educational institutions in antiquity. Founded by one of the greatest thinkers of all times, its activity as a centre of philosophical and scientific research spanned at least three centuries (from ca. 387 to ca. 86 B.C.), while the influence it has exerted on contemporary and later philosophical and scientific thought is almost impossible to overestimate. The Academy's history is supposed to reflect not only the theoretical aspirations (...) of its founder and his followers, but also the manner in which they believed their views should operate within a given social context.

Set of articles, fruits of research by anthropologists, focused on the health area. First work of its kind in the country, which deepens mental health issues, cosmological view of specific groups, relationships between body, mind and culture and healing issues seen from the perspective of various popular religions. The work contrasts with the efforts of health scholars to approach anthropological approaches, so that it becomes an instrument for understanding the health / disease phenomenon and its complex articulation processes.

According to enactivism all living systems, from single cell organisms to human beings, are ontologically endowed with some form of teleological and sense-making agency. Furthermore, enactivists maintain that: there is no fixed pregiven world and as a consequence all organisms “bring forth” their own unique “worlds” through processes of sense-making. The first half of the paper takes these two ontological claims as its central focus and aims to clarify and make explicit the arguments and motivations underlying them. Our analysis here (...) highlights three distinct but connected problems for enactivism: these arguments do not and cannot guarantee that there is no pregiven world, instead, they end up generating a contradiction whereby a pregiven world seems to in fact be tacitly presupposed by virtue of a reliance on a tacit epistemic perspectivalism which is also inherently representationalist and as a consequence makes it difficult to satisfactorily account for the ontological plurality of worlds. Taking these considerations on board, the second half of the paper then aims to develop a more robust ontologically grounded enactivism. Drawing from biosemiotic enactivism, science and technology studies and anthropology, the paper aims to present an account which both rejects a pregiven world and coherently accounts for how organisms bring forth ontologically multiple worlds.

O livro apresenta o Método Paulo Freire, a mais importante proposta pedagógica pensada a partir da realidade do Terceiro Mundo. Apesar dos mais de vinte anos que o separam da primeira edição, o Método mantém atual a avaliação do papel da educação, o vigor de suas perspectivas e sua aplicabilidade.

La pedagogía de Freire es un método de cultura popular cuya finalidad inmediata es la alfabetización, y su dimensión más amplia es la educación como práctica de la libertad. En esta dimensión, educadores y educandos son simultáneamente educadores y educandos los unos de los otros; juntos inician como oprimidos la tarea histórica de liberarse a sí mismos y liberar a los opresores.

The standard approach to the core phenomenology of thought insertion characterizes it in terms of a normal sense of thought ownership coupled with an abnormal sense of thought agency. Recently, Fernández (2010) has argued that there are crucial problems with this approach and has proposed instead that what goes wrong fundamentally in such a phenomenology is a sense of thought commitment, characterized in terms of thought endorsement. In this paper, we argue that even though Fernández raises new issues that enrich (...) the topic, his proposal cannot rival the version of the standard approach we shall defend. (shrink)

Experimental results in reference to Brazilian children and adults are presented in the context of current discussions about essentialism and folkbiology. Using an adoption paradigm, we replicate the basic findings of a previous article in this journal concerning the early emergence in children of a birth-parent bias. This cognitive bias supports the claim that causal essentialism cross-culturally constrains the reasoning about the origin, development and maintenance of the characteristics and identity of living kinds. We also report some intriguing differences with (...) earlier findings that speak to theoretical and methodological issues of cultural relativity. (shrink)

This article examines the evaluative nature of the folk concepts of weakness and strength of will and hypothesizes that their evaluative nature is strongly connected to the folk concepts of blame and credit. We probed how people apply the concepts of weakness and strength of will to prototypical and non-prototypical scenarios. While regarding prototypical scenarios the great majority applied these concepts according to the predictions following from traditional philosophical analyses. When presented with non-prototypical scenarios, people were divided. Some, against traditional (...) analyses, did not apply these concepts, which we explain in terms of a clash of evaluations involving different sorts of blame and credit. Others applied them according to traditional analyses, which we explain in terms of a disposition to be reflective and clearly set apart the different sorts of blame and credit involved. Still others applied them in an inverse way, seemingly bypassing the traditional components resolution and be.. (shrink)

Profound theoretical and philosophical approach to contemporary music Unsayable Music presents theoretical, critical and analytical reflections on key topics of contemporary music including acoustic, electroacoustic and digital music, and audiovisual and multimedia composition. Six essays by Paulo C. Chagas approaching music from different perspectives such as philosophy, sociology, cybernetics, musical semiotics, media, and critical studies. Chagas’s practical experience, both as a composer of contemporary music and sound director of the Electronic Music Studio of Cologne, nourishes his observations on the (...) specific creativity that emerges with the use of the technical apparatus, the development of the electronic music studio, the different aesthetics of electroacoustic music, and the forms of audiovisual and multimedia composition. The title Unsayable Music is a reference to Wittgenstein, who suggested that sound is only the surface of music and that the musical work conceals something more profound that can hardly be described by philosophical models or scientific theories.

Paulo Margutti e José Crisóstomo discutem sobre a possiblidade ou a impossibilidade de ultrapassar o representacionismo correspondentista e principalmente o eventual linguocentrismo da filosofia contemporânea, pós-virada linguística, em que parece que da linguagem pode-se passar apenas à linguagem, a cujo círculo mágico estaríamos, desse modo, inevitavelmente presos. Sendo assim, o mundo “aí fora” novamente nos escapa e o relativismo, o agnosticismo e o ceticismo de novo nos espreitam. Em Nietzsche, é a linguagem, sempre metafórica, que se adéqua aos nossos (...) modos prático-perspectivistas, corpóreos e afetivos, de “recortar” o mundo, ou é o contrário? E em Maturana, o que vem primeiro? Para Crisóstomo, para quem no começo está o ato, ultrapassamos tudo isso através de nosso emaranhamento prático com o mundo, por meio da natureza sensível criativa de nossas práticas e pela tradução de crenças em condutas. Enquanto que, para Margutti, nada disso parece deslocar a primazia incontornável da linguagem, como prática ela própria. Sobre isso, Margutti pergunta pelo suposto aproveitamento, por Crisóstomo, no seu ponto de vista prático-poiético criativo, em versão alegadamente não idealista nem dualista, da noção de autoconsciência, central no idealismo alemão.

Abstract: In a previous article in this journal, Daniel Kelly, Stephen Stich, Kevin Haley, Serena Eng and Daniel Fessler report data that, according to them, foster scepticism about an association between harm and morality existent in the Turiel tradition ( Kelly et al. , 2007 ). This article challenges their interpretation of the data. It does so by explicating some methodological problems in the Turiel tradition that Kelly et al. themselves in a way inherit and by drawing on new evidence (...) coming from a partial replication of their research.

1a̲ parte. O período colonial (1500-1822).

Here a wide distribution of meiotic machinery is shown, indicating the occurrence of sexual processes in all major eukaryotic groups, without exceptions, including the putative “asexuals.” Meiotic machinery has evolved from archaeal DNA repair machinery by means of ancestral gene duplications. Sex is very conserved and widespread in eukaryotes, even though its evolutionary importance is still a matter of debate. The main processes in sex are plasmogamy, followed by karyogamy and meiosis. Meiosis is fundamentally a chromosomal process, which implies recombination (...) and ploidy reduction. Several eukaryotic lineages are proposed to be asexual because their sexual processes are never observed, but presumed asexuality correlates with lack of study. The authors stress the complete lack of meiotic proteins in nucleomorphs and their almost complete loss in the fungus Malassezia. Inversely, complete sets of meiotic proteins are present in fungal groups Glomeromycotina, Trichophyton, and Cryptococcus. Endosymbiont Perkinsela and endoparasitic Microsporidia also present meiotic proteins. (shrink)

This paper concerns a recently discovered, puzzling asymmetry in judgments of whether an action is intentional or not (Knobe, Philosophical Psychology 16:309–324, 2003a ; Analysis 63:190–193, b ). We report new data replicating the asymmetry in the context of scenarios wherein an agent achieves an amoral or immoral goal due to luck. Participants’ justifications of their judgments of the intentionality of the agent’s action indicate that two distinct folk concepts of intentional action played a role in their judgments. When viewed (...) from this perspective, the puzzle disappears, although the asymmetry remains. (shrink)

"Mentoring the Mentor" recreates a Freirian dialogue in a printed format. In this volume, sixteen distinguished scholars engage in a critical and thoughtful exchange with Paulo Freire. While some contributors voice appreciation for Freire's ideas and for what it means to -reinvent Freire- in a North American context, others offer sharp critiques of Freire's philosophy and, of equal importance, of the various interpretations of his work. A variety of chapters describe specific uses which have been made of Freire's ideas (...) in diverse educational contexts, from the New York City public schools to the revolutions in Guinea Bissau and Eritrea. Finally, Paulo Freire himself responds to the major issues which are raised in the volume and invites readers to share in a continuing lively dialogue about the meaning of democratic and revolutionary education. -The fundamental task of the mentor is a liberatory task. It is not to encourage the mentor's goals and aspirations and dreams to be reproduced in the mentees, the students, but to give rise to the possibility that the students become the owners of their own history. This is how I understand the need that teachers have to transcend their merely instructive task and to assume the ethical posture of a mentor who truly believes in the total autonomy, freedom, and development of those he or she mentors.- (from Chapter Sixteen, -A Response- by Paulo Freire)".

In this volume, we have chosen to highlight the importance of education to human rights by reprinting two articles written by Paulo Freire in 1970 for the _Harvard Educational Review_. These articles contain many of Freire's original ideas on human rights and education—issues that are central to his work. Freire was a pioneer in promoting the universal right to education and literacy as part of a commitment to people's struggle against oppression. As Jerome Bruner recognized after Freire's death in (...) May 1997, Freire left as a legacy his commitment to basic human rights: "He was a brave man as well as a far-sighted one. He made us aware of our mindless cruelties, and now the challenge to all of us is to do something about those cruelties.". (shrink)

Upon its recent publication in Portuguese, Paulo Freire’s newest book became an instant success. This English translation is sure to meet with similar acclaim. In Teachers as Cultural Workers, Freire speaks directly to teachers about the lessons learned from a lifetime of experience as an educator and social theorist. No other book so cogently explains the implications for classroom practice of Freire’s latest ideas and the pathbreaking theories found in Pedagogy of the Oppressed and other treatises.This book challenges all (...) who teach to reflect critically on the meaning of the act of teaching as well as the meaning of learning. Freire shows why a teacher’s success depends on a permanent commitment to learning and training, as part of an ongoing appraisal of classroom practice. By observing the curiosity of students and the manner through which students develop strategies for learning, the teacher is helped in discovering doubts, successes, and the teacher’s mistakes. When teachers open themselves to recognize the different roads students take in order to learn, they will become involved in a continual reconstruction of their own paths of curiosity, opening the doors to habits of learning that will benefit everyone in the classroom.

O presente trabalho objetiva fazer uma análise sobre algumas das principais temáticas elaboradas pelo pensador argentino Luis Alberto Warat, quais sejam: o antropofagismo waratiano, o reencontro com a subjetividade perdida e a carnavalização. Para isso, analisou- se uma das obras mais caras do pensamento waratiano: A ciência jurídica e seus dois maridos. Buscou-se através da análise empreendida, elaborar uma crítica sobre paradigmas tradicionais de ciência, incluindo aqui, a própria Ciência do Direito. Sobreleva-se o caráter de indisciplina das atividades artístico-literárias para (...) insinuar as falhas históricas das disciplinas bem instituídas, do pensamento e da cultura dominantes. Visa-se, portanto, maior interação entre aquilo que se entende como ciência e a subjetividade humana como um todo. (shrink)
