Among many contemporary challenges faced by our society is the moral and ethical education of new generations. Young students bring to school a variety of cultural (including religious) backgrounds and worldviews, not rarely of very heterogeneous and conflicting nature. In spite of the secular nature of Brazilian public education system, Federal Constitution of 1988 and the Law of Directives and Bases of National Education (issued in 1996) allow religious education to be offered in public schools. Therefore, religious education is nowadays (...) offered in many schools, spreaded around a country marked by extensive social, economical, ethnical and cultural diversity. A number of researches point to emerging issues of religious nature that are now present in classrooms of many school disciplines -among them, Biology. Article number 205 of Brazilian Federal Constitution reads that education is a right that assists to all, no matter which race, social class or religious affiliation, so that citizens' full development is a primordial objective of education, followed by preparation for the practice of citizenship and work qualification. Schools must be formal spaces for teaching, according to strong and universal ethical principles such as: equality, freedom for learning, pluralism of ideas, and investigating and disseminating art and knowledge, among others. It is a State duty, therefore, to promote and stimulate education with the collaboration of society. As Federal Constitution also reads that each family has this responsibility with children too, it is a matter of concern that, in last years, social and economical factors are forcing families to transfer these duties to schools and teachers. In schools, a number of Biology contents may bring up students' beliefs and worldviews impregnated of common sense, and also feelings of religiosity. These emergent elements may have a significant value for enriching pedagogical interactions, either with discussions about social and cultural plurality, or with challenging or even disrupting educational situations, in which conflicts and oppositions will be brought up as a result of diversity of opinions and views. It is our position that these are two possible ways that can be followed by a teacher, depending on his/her methodological direction and ethical position. We also understand that each teacher, especially Biology teachers working in secondary education, should welcome these discussions in classroom, organizing opportunities for ethical debates, including issues of religious nature, this way presenting scientific concepts of biological phenomena, but also respecting students' cultural and religious values. In official documents that guide the Biology teaching in basic Brazilian education -the directives, the directions and the national parameters -contents such as Ecology and Evolution play a central role due to their integrational power. However, Biology teachers often face a number of difficulties when trying to follow these directives. Problems in their own education, the reductionist and highly content-based nature of Biology education, as well as severe material restrictions for teachers' work in schools are some of the difficulties that may account for this situation. In spite of these difficulties, issues such as abortion, euthanasia, drugs, sexuality, Biological Evolution (BE) and origin of living beings always bring, in classroom, controversial questions that must be part of every teacher's pedagogical practice. Teaching BE has always raised a number of polemical issues, followed by deep conceptual and ethical implications. Therefore, any contribution aimed at helping its approach as a necessary content in Biology teaching is welcomed. This paper aims at showing some of the conditions, attitudes and arguments that may be useful for the teaching of BE. Among them, we point to nonoverlapping magisteria (NOMA) principle, an ethical and methodological principle proposed in 1997 by palaeontologist Stephen Jay Gould. We understand that Gould's principle offers conditions and opportunities to develop what Brazilian educator Paulo Freire calls a dialogical, libertarian and dialectic education, and this paper will follow his educational perspective. Basically, NOMA principle states that both religion and science have their own separate domain. These separate domains should be respected, avoiding their overlapping in issues concerned with each of them separately. However, there are themes, as mentioned above, in which it is possible to identify elements for each of those domains. Biology teachers must then have a very clear view of the differences between explanations offered by each of these domains, when working with their students about contentious issues such as BE. Freire, when describing the necessary elements for educational practice, points that the act of teaching demands both ethics and corporification of words through practice. Opposing his view to simple Puritanism principles, he states that educational practices should be rigorous evidences of decency and purity. Freire also states that, as an act of respect towards any human being, school contents shouldn't be taught without respect to students' moral education. Therefore, according to Freire, to think "right" means to act "right". For Freire, a teacher that is genuinely concerned with moral and ethical development of his/her students will act accordingly in classroom, bringing into discussion issues that benefit both from science knowledge and also from students' non-scientific worldviews. We propose that Gould's NOMA principle can be developed by teachers as a fruitful strategy for teaching Biology contents as BE. Learning from some examples taken from school contents, we aim to show that the application of such principle in school would help clarifying the nature and foundations of evolutionary theories, mainly neo-Darwinism, as well as the non-overlapping domains of scientific and religious worlds. Therefore, it would be possible to maintain the necessary distance (demanded for ethical reasons) from subjective issues, without any harm for the necessary, objective and deep appreciation of scientific knowledge. In this perspective, we understand that well-known incompatibilities between science and religion could be clarified and discussed with students, since each of these domains have an important role in pupils' personal development.

De manera inmediata y tradicional pensamos que hablar sobre política exige forzosamente ligarla a la idea de conflicto. Si bien es cierto que el carácter político marca ciertos modos de habitar el mundo, también es relevante aclarar que, a partir del concepto que tengamos de política, podremos darnos cuenta de si la idea de conflicto es inherente a esta o si la política puede ser pensada desde otro horizonte. Hans-Georg Gadamer nos ofrece una serie de reflexiones hermenéuticas en torno al (...) lenguaje y al diálogo; a partir de allí, intentamos atisbar un concepto de política no solo inherente al conflicto, sino también a su parte medular como lo es el diálogo prudente. Pensar en una política dentro del marco de un horizonte dialógico nos permite arrojar luz a problemas particulares que nos aquejan hoy, los cuales nos interpelan a pensar y repensarlos para comprender por qué hemos llegado a ser lo que somos.

Is the societal-level of analysis sufficient today to understand the values of those in the global workforce? Or are individual-level analyses more appropriate for assessing the influence of values on ethical behaviors across country workforces? Using multi-level analyses for a 48-society sample, we test the utility of both the societal-level and individual-level dimensions of collectivism and individualism values for predicting ethical behaviors of business professionals. Our values-based behavioral analysis indicates that values at the individual-level make a more significant contribution to (...) explaining variance in ethical behaviors than do values at the societal-level. Implicitly, our findings question the soundness of using societal-level values measures. Implications for international business research are discussed. (shrink)

This article provides current Schwartz Values Survey (SVS) data from samples of business managers and professionals across 50 societies that are culturally and socioeconomically diverse. We report the society scores for SVS values dimensions for both individual- and societal-level analyses. At the individual-level, we report on the ten circumplex values sub-dimensions and two sets of values dimensions (collectivism and individualism; openness to change, conservation, self-enhancement, and self-transcendence). At the societal-level, we report on the values dimensions of embeddedness, hierarchy, mastery, affective (...) autonomy, intellectual autonomy, egalitarianism, and harmony. For each society, we report the Cronbach’s α statistics for each values dimension scale to assess their internal consistency (reliability) as well as report interrater agreement (IRA) analyses to assess the acceptability of using aggregated individual level values scores to represent country values. We also examined whether societal development level is related to systematic variation in the measurement and importance of values. Thus, the contributions of our evaluation of the SVS values dimensions are two-fold. First, we identify the SVS dimensions that have cross-culturally internally reliable structures and within-society agreement for business professionals. Second, we report the society cultural values scores developed from the twenty-first century data that can be used as macro-level predictors in multilevel and single-level international business research.

From the most prominent thinkers in Latin American philosophy, literature, politics, and social science comes a challenge to conventional theories of globalization. The contributors to this volume imagine a discourse in which revolution requires no temporalized march of progress or takeovers of state power but instead aims at local control and the material conditions for human dignity.

Background Doctors are increasingly faced with end-of-life decisions. Little is known about how medical students approach euthanasia. The objective of this study was to evaluate, among medical students and residents, the view on euthanasia and its variants; correlate such a view with empathy and religiosity/spiritualism; and with the stages of medical training in Brazil. Methods This is an exploratory cross-sectional study using an online questionnaire to be filled out on a voluntary basis among medical students and residents, consisting of: socio-demographic (...) data, an empathy questionnaire and questions with elaborate clinical cases that typify situations of the variants of euthanasia. Results From 1550 invitations, 273 volunteer participants responded (17.6%). The percentages of strong agreement/agreement on the concepts were: passive euthanasia (72.9%); active euthanasia (22.3%), orthothanasia (90.1%), dysthanasia (18.7%), assisted suicide (33%) and sedation (82.8%). Passive euthanasia, active euthanasia, dysthanasia and assisted suicide showed greater refusal with increasing length of medical training. Religious belief and degree of empathy did not significantly influence the opinion about the concepts. Strong agreement/agreement were: passive euthanasia (72.9%); active euthanasia (22.3%), orthothanasia (90.1%), dysthanasia (18.7%), assisted suicide (33%) and sedation (82.8%). Conclusions Passive euthanasia, active euthanasia, dysthanasia and assisted suicide showed greater refusal with increasing length of medical training. The external validation of our findings relies on the distinct legal, cultural, and religious frameworks found across various countries. (shrink)

In this paper, I engage with the motif of “the pluriverse” such as it has increasingly been used in the past few years in several strands of critical humanities pertaining to the so-called “ontological turn”: science and technology studies (Bruno Latour, Isabelle Stengers), critical geography and political ontology (Mario Blaser), cultural anthropology (Marisol de la Cadena, Arturo Escobar, Eduardo Viveiros de Castro), decolonial thought (Walter Mignolo), or posthuman feminism (Donna Haraway). These various iterations of the figure of the (...) pluriverse constitute a loose network of textual traces, a supposedly new scene for ‘humanities’, organized around what is understood as a pluralistic ontology. In political terms, the discourse of the pluriverse presents itself as a strategic response to the violence of universalism. It advocates for a multiversal ethics, a pluriversal cosmopolitics based on interspecies and multi-natural kinships, and more aware of the multiplicity of worlds and world-making practices that make up the post-globalization scene. Based on readings of Bruno Latour, Eduardo Viveiros de Castro, Arturo Escobar and Marisol de la Cadena among others, I argue that the notion of pluriversality remains self-contradictory and self-defeating as long as it relies on an ontological representation of world/worlds in the form of copresence. Drawing on Derrida’s deconstruction of the concept of world (cosmos, mundus) in his late writings, I propose to think an exorbitant plurality, before the pluriverse and before being. Beyond ontological pluralism, Derrida’s “infinity of untranslatable worlds” also signifies an irreducible interruption, the end of the world, of any “world-in-common”, thus raising the stakes for the ethical demand towards the other.

The iconoclastic Brazilian anthropologist and theoretician Eduardo Viveiros de Castro, well known in his discipline for helping initiate its “ontological turn,” offers a vision of anthropology as “the practice of the permanent decolonization of thought.” After showing that Amazonian and other Amerindian groups inhabit a radically different conceptual universe than ours—in which nature and culture, human and nonhuman, subject and object are conceived in terms that reverse our own—he presents the case for anthropology as the study of such “other” (...) metaphysical schemes, and as the corresponding critique of the concepts imposed on them by the human sciences. Along the way, he spells out the consequences of this anthropology for thinking in general via a major reassessment of the work of Claude Lévi-Strauss, arguments for the continued relevance of Deleuze and Guattari, dialogues with the work of Philippe Descola, Bruno Latour, and Marilyn Strathern, and inventive treatments of problems of ontology, translation, and transformation. Bold, unexpected, and profound, Cannibal Metaphysics is one of the chief works marking anthropology's current return to the theoretical center stage. (shrink)

Predictivists use the no miracle argument to argue that “novel” predictions are decisive evidence for theories, while mere accommodation of “old” data cannot confirm to a significant degree. But deductivists claim that since confirmation is a logical theory-data relationship, predicted data cannot confirm more than merely deduced data, and cite historical cases in which known data confirmed theories quite strongly. On the other hand, the advantage of prediction over accommodation is needed by scientific realists to resist Laudan’s criticisms of the (...) no miracle argument. So, if the deductivists are right, the most powerful argument for realism collapses. There seems to be an inescapable contradiction between these prima facie plausible arguments of predictivists and deductivists; but this puzzle can be solved by understanding what exactly counts as novelty, if novel predictions must support the no miracle argument, i.e., if they must be explainable only by the truth of theories. Taking my cues from the use-novelty tradition, I argue that (1) the predicted data must not be used essentially in building the theory or choosing the auxiliary assumptions. This is possible if the theory and its auxiliary assumptions are plausible independently of the predicted data, and I analyze the consequences of this requirement in terms of best explanation of diverse bodies of data. Moreover, the predicted data must be (2) a priori improbable, and (3) heterogeneous to the essentially used data. My proposed notion of novelty, therefore, is not historical, but functional. Hence, deductivists are right that confirmation is independent of time and of historical contingencies such as if the theorist knew a datum, used it, or intended to accommodate it. Predictivists, however, are right that not all consequences confirm equally, and confirmation is not purely a logical theory-data relation, as it crucially involves background epistemic conditions and the notion of best explanation. Conditions (1)–(3) make the difference between prediction and accommodation, and account for the confirming power of theoretical virtues such as non ad-hocness, non-fudging, non-overfitting, independence and consilience. I thus show that functional novelty (a) avoids the deductivist objections to predictivism, (b) is a gradual notion, in accordance with the common intuition that confirmation comes in degrees, and (c) supports the no miracle argument, so vindicating scientific realism.

There are two possible realist defense strategies against the pessimistic meta-induction and Laudan’s meta-modus tollens: the selective strategy, claiming that discarded theories are partially true, and the discontinuity strategy, denying that pessimism about past theories can be extended to current ones. A radical version of discontinuity realism is proposed by Gerald Doppelt: rather than discriminating between true and false components within theories, he holds that superseded theories cannot be shown to be even partially true, while present best theories are demonstrably (...) completely true. I argue that this position, running counter both the cumulativity of science and fallibilism, is untenable; it cannot account for the success of past theories, nor for the failures of current theories, and rather than shutting the door to the pessimistic historical objections it opens it wide. The best strategy, instead, joins the selective idea there was both some truth and some falsity in discarded theories, like in current ones, with the moderate discontinuity idea that the truth rate in present best theories is much greater than in past ones.

El texto está estructurado en tres partes: en la primera, se presenta un breve panorama de los niveles de apoyo que tiene la democracia en América Latina, destacando en especial las condiciones de desigualdad que hay en México; en la segunda, se analiza (...) la propuesta de Norberto Bobbio, para quien la democracia se caracteriza por ser representativa, política y formal; en la tercera, se recuperan algunos elementos de uno de sus principales discípulos, Luigi Ferrajoli, quien ha señalado la necesidad de la democracia sustancial y los derechos fundamentales para limitar el poder de la democracia formal. Palabras clave: Democracia; derechos fundamentales; desigualdad social Limits of Democracy and Social JusticeIn this article I point out some necessary conditions for the development and stability of contemporary democracy; conditions which are linked to both, the problem of the limitation of its power and social justice. The text is structured into three parts. In the first I present a brief overview of the levels of support that democracy has in Latin America, focusing especially on the inequality conditions existing in Mexico. In the second part I analyze the proposal of Norberto Bobbio´s, for whom democracy is characterized by being representative, political and formal. In the third part, I recall some points dealt with by one of his disciples, Luigi Ferrajoli, who has pointed to the need for substantial democracy and fundamental rights to limit the power of formal democracy.

Hablar de infinitud parecería conducirnos a dimensiones abstractas o lejanas; se trataría entonces de un discurso que pertenecería a lo meramente lógico o insustancial. En este estudio se pretende, por el contrario, hablar de la infinitud como realidad, como aquello en lo que estamos y que nos constituye. Pero no se trata solamente de la realidad divina, tardíamente considerada sin embargo como infinita, sino también de la realidad toda, que procede en definitiva de lo divino infinito como de su fuente (...) y sustento radical, y que debido a ello no puede coherentemente ser pensada sino como participando de algún modo de lo infinito originante. La amplia y sutil peripecia especulativa de la reflexión occidental, desde lo griegos hasta la actualidad, sobre la infinitud o no-limitación de la realidad es aquí objeto de atención y análisis sostenidos.

According to Schroeder-Heister 2018, proof-theoretic semantics is ‘an alternative to truth-condition semantics. It is based on the fundamental assumption that the central notion in terms of which meanings are assigned to certain expressions of our language, in particular to logical constants, is that of proof rather than truth. In this sense proof-theoretic semantics is semantics in terms of proof. Proof-theoretic semantics also means the semantics of proofs, i.e. the semantics of entities which describe how we arrive at certain assertions given (...) certain assumptions.' This text advocates that proof-theoretic semantics, as described above, was an approach to semantical issues in logic that appeared in mainstream philosophical literature at least a couple of centuries before the tradition of general proof theory (cf. Prawitz 1971) came into being. This is done by means of an interpretive analysis of Kant’s 1762 essay Die falsche Spitzfindigkeit der vier syllogistischen Figuren, in which two theses are argued: first, that the issue of justifying the logical validity of inferences is approached by Kant in this text, in a strong sense, in terms of proofs; and second, that the purpose of his effort is to establish a point concerning the semantical equivalence between certain distinct valid inferences.

Criticisms à la Laudan can block the “no miracles” argument for the (approximate) truth of whole theories. Realists have thus retrenched, arguing that at least the individual claims deployed in the derivation of novel predictions should be considered (approximately) true. But for Lyons (2002) there are historical counterexamples even to this weaker “deployment” realism: he lists a number of novel predictions supposedly derived from (radically) false claims. But if so, those successes would seem unexplainable, even by Lyons’ “modest surrealism” or (...) other surrogates to realism. In fact, I argue, some of those predictions were an easy guess, or independently probable in the light of available evidence; hence, they are no counterexamples to deployment realism, for the no miracles argument wouldn’t apply to them. In other instances, pace Lyon, the prediction was actually false, and could be reinterpreted as true only by interpreting as true also the claim from which it was derived; or again, a false claim was employed in the derivation of a true prediction, but inessentially, the essential role being played by a weaker true claim. But as soon as the paradoxical air of such historical cases is explained away in any of these manners, they cease to represent counterexamples to deployment realism. If, as I suggest, all of them can be dealt with by these strategies, a theoretical claim can still be assumed to be true if it is crucial in deriving an improbable novel prediction. (shrink)

El propósito de este artículo consiste en mostrar el carácter social del contractualismo de Fichte. Para realizar ese propósito se comienza examinando la conexión entre trabajo y ciudadanía como una condición de la legitimidad política. Luego se presenta esa conexión en el marco del siempre posible desarrollo histórico de la naturaleza humana. Por último, se indican las razones de la recepción de Fichte como un precursor del socialismo germánico.

Gerald Doppelt claims that Deployment Realism cannot withstand the antirealist objections based on the “pessimistic meta-induction” and Laudan’s historical counterexamples. Moreover it is incomplete, as it purports to explain the predictive success of theories, but overlooks the necessity to explain also their explanatory success. Accordingly, he proposes a new version of realism, presented as the best explanation of both predictive and explanatory success, and committed only to the truth of best current theories, not of the discarded ones. Elsewhere I criticized (...) his new brand of realism. Here instead I argue that Doppelt has not shown that Deployment Realism cannot solve the problems raised by the history of science, explaining explanatory success does not add much to explaining novel predictive success, and Doppelt is right that truth is not a sufficient explanans, but for different reasons, and this does not refute Deployment Realism, but helps to detail it better. In a more explicit formulation, the realist IBE concludes not only to the truth of theories, but also to the reliability of scientists and scientific method, the order and simplicity of nature, and the approximate truth of background theories.

Many formulations of scientific realism (SR) include some commitment to metaphysical realism (MR). On the other hand, authors like Schlick, Carnap and Putnam held forms of scientific realism coupled with metaphysical antirealism (and this has analogies in Kant). So we might ask: do scientific realists really need MR? or is MR already implied by SR, so that SR is actually incompatible with metaphysical antirealism? And if MR must really be added to SR, why is that so? And which additional arguments (...) scientific realists need to support it? After reviewing and classifying a number of different kinds of realisms, metaphysical and not, I answer that SR and MR are logically independent of each other, so that there is no logical inconsistency in holding SR while rejecting MR. However, I argue that the “no miracle” argument (NMA) not only is the “ultimate” argument for SR, but by the same token it also supports MR. Therefore one cannot effectively defend SR without also subscribing to MR, but this can be done at no additional argumentative cost. I show this by discussing not only the standard version of the NMA, but also three more versions which are not usually considered as such in the literature. (shrink)

This paper briefly presents an account, partially based upon Ryle’s approach, of the functions of intentional psychological terms as they are used in ordinary language. According to this account, intentional psychological terms describe known patterns of behavior that are determined by selective mechanisms of causation. That is, these terms describe relations between certain responses, selected on the basis of the consequences they produce in the environment, and contexts of their occurrence, to which they become associated. Intentional psychological terms do not (...) point to inner causes of a given behavior, but can explain it only in the sense of stating that it could be expected to occur, if we can identify its behavior pattern and the context in which it occurs. We proceed then to examine three main objections that have been raised against Ryle’s position, namely: (a) Davidson’s challenge to the non-causal accounts of reason-explanations; (b) Armstrong’s worries about “leaving the counterfactuals hanging in the air”; and (c) the holistic objection to the (wrongly) presumed Ryle’s atomism. We aim at showing that none of these objections pose serious problems to the proposed account. (shrink)

In this paper, we analyze the legal situation regarding physician-assisted suicide in the world. Our hypothesis is that the prohibitive stance on physician-assisted suicide in most societies in the world today seems to be related to our moral attitudes toward suicide. This brings us to a discussion about life itself. We claim that the total lack of legal protection for physician-assisted suicide from international organizations and most countries in the world lies in a philosophical assumption that supports much of our (...) common beliefs about what life really is. This assumption states that life must be thought of as not belonging exclusively to the individual. We argue that this assumption is a misconception that can be heard in the debate on suicide. Consequently we endorse a different conception of life which tends to favor a pro-choice stance towards suicide and assisted death in general. This position takes the patient’s decision about when to die more seriously. We conclude that there is no reason why physician-assisted suicide does not deserve legal protection as an individual right to die under international law. (shrink)

With special relativity, we seem to be facing a conundrum. It is a very well-tested theory; in this way, the Minkowski spacetime must be “capturing” essential features of space and time. However, its geometry seems to be incompatible with any sort of global notion of time. We might only have local notions of now (present moment) and time flow, at best. In this note, we will explore the possibility that a pretty much global notion of now (and time flow) might (...) be hiding in plain sight in the geometry of the Minkowski spacetime. (shrink)

Epistemologists have debated at length whether scientific discovery is a rational and logical process. If it is, according to the Artificial Intelligence hypothesis, it should be possible to write computer programs able to discover laws or theories; and if such programs were written, this would definitely prove the existence of a logic of discovery. Attempts in this direction, however, have been unsuccessful: the programs written by Simon's group, indeed, infer famous laws of physics and chemistry; but having found no new (...) law, they cannot properly be considered discovery machines. The programs written in the Turing tradition, instead, produced new and useful empirical generalization, but no theoretical discovery, thus failing to prove the logical character of the most significant kind of discoveries. A new cognitivist and connectionist approach by Holland, Holyoak, Nisbett and Thagard, looks more promising. Reflection on their proposals helps to understand the complex character of discovery processes, the abandonment of belief in the logic of discovery by logical positivists, and the necessity of a realist interpretation of scientific research.
