Este artigo, de caráter ensaístico, não se furta a pensar o fenômeno de maior proeminência no momento em que fora escrito, a pandemia desencadeada pelo Covid-19. Partindo literalmente da premissa foucaultiana, segundo a qual a filosofia deve ter como alvo o tempo presente, e abalizado por reflexões recentes de filósofos contemporâneos influenciados por Foucault, como Paul B. Preciado e Roberto Esposito, defendo a hipótese de que o vírus carrega em si, como um espelho, tudo o que ainda não conseguimos deixar (...) de ser. Com efeito, a abordagem aqui adotada lança mão da estratégia, já recorrente na filosofia contemporânea, de ampliar a noção de “vírus” como metáfora pertinente para os mais diversos fenômenos societários. Após introduzir o que está em jogo neste contingente virótico e global, decomponho a reflexão em quatro partes: enquadramento – de uma atmosfera previamente carregada de certos hábitos de exceção e anticorpos fronteiriços; estranhamento – como princípio da imunização e da redistribuição da vulnerabilidade; confinamento – como disciplina assimétrica de sobrevivência e autossacrifício; desaparecimento – como horizonte ontológico de uma existência inerte que nos espelha. O que me interessa aqui é, mais do que delinear uma interpretação filosófica da pandemia, indiciar a lógica insuspeita e virulenta que há décadas nos cerceia enquanto corpos e anticorpos descartáveis. Concluo, à guisa do diagnóstico de Paul B. Preciado, segundo o qual o vírus atua “à nossa imagem e semelhança”, que o fenômeno pandêmico implica o recrudescimento do paradoxo neoliberal segundo o qual, para “sobrevivermos”, devemos sacrificar a nós mesmos.

Este artigo visa refletir sobre a moral contemporânea a partir da ética de Nietzsche, tendo como foco principal a sua _Genealogia da Moral_ e, como contraponto a ser problematizado, o livro _The weariness of the self_ do sociólogo francês Alain Ehrenberg. De início, para analisar alguns tipos morais relevantes na primeira obra, revisamos o itinerário genealógico entre a “vontade de verdade” cristã e o niilismo budista (ou “ceticismo em matéria de moral”), destacando ainda alguns comentários de Nietzsche em torno de (...) Kant e o utilitarismo inglês. A autocrítica kantiana do conhecimento, afinal, manteve intacta a valoração negativa (cristã) da vida ao não questionar o valor em si da verdade. Por sua vez, ao arrogar o bem definitivo à felicidade, o utilitarismo inglês tornou a compaixão cristã compatível com o “ceticismo em matéria de moral”. A partir disso, argumentamos que a nova figura moralmente exemplar — não sendo mais a do cristão, alvo principal da genealogia nietzschiana — é a do budista, uma vez que este adere integralmente o niilismo. Em um segundo momento deste estudo, problematizamos a tese de Ehrenberg segundo a qual a figura do “indivíduo soberano” teria hoje se tornado hegemônica sob a égide da categoria da depressão. Não sendo concebível, sob o prisma nietzschiano, tal “indivíduo soberano” deprimido descrito por Ehrenberg, observamos, por fim, que é o niilismo que efetivamente se prolifera hoje: a partir da ilusão de superação total da moralidade, a moral contemporânea cultiva a fraqueza e o cansaço fisiológico através de um programa de combate irrestrito ao sofrimento.

Tomando como ponto de partida a célebre sentença "torna-te o que tu és”, do poeta grego Píndaro, este estudo aborda as relações entre arte, hermenêutica e autoformação, na esteira da filosofia nietzschiana. Para tanto, o ato poético é entendido como indissociável da experiência vivida e, sobremaneira, do movimento do vir a ser, com o entendimento da arte como um modo de vida. Essa abordagem é levada a cabo tendo em vista as implicações educacionais de um tal princípio ético pautado na (...) transformação de si como chave para a compreensão e releitura do mundo. (shrink)

Este estudo delineia coordenadas conceituais para a investigação do discurso e da visualidade em arte e design a partir do ferramental de Michel Foucault. Não é o caso de propor um “modo de usar” a obra desse filósofo e sim uma leitura possível sobre tal arsenal, com vistas a um horizonte que o excede. Após assinalar o caráter dinâmico e correlacional dessa proposição, as coordenadas são ordenadas em: (1) relações de poder, (2) regimes de verdade, (3) discurso e visualidade, por (...) fim, (4) arte e design. Ao final, argumenta-se que a análise das correlações discursivo-visuais permite vislumbrar como as práticas contemporâneas estão sempre enredadas em valores, condutas e modos de olhar. O artigo sugere ainda que a arte e o design poderiam se beneficiar da leitura ora proposta, que abre um novo horizonte interpretativo em torno da contínua (re)elaboração de nossas experiências e subjetividades.

O objetivo deste artigo é explorar a relação de complementaridade entre o real e o imaginário, com foco no aspecto estético-hermenêutico que constitui a expressividade das imagens. Partimos da problematização do estatuto epistemológico da imagem no pensamento ocidental, recorrendo a autores que privilegiam a imagem como expressão do real. Por fim, discutirmos a prevalência da “imagem estética”, por meio da qual o mundo explicita-se como aparência de mundo no cenário contemporâneo. Por este caminho, propomos uma abordagem da imagem que possa (...) abranger a intensidade dos fluxos afetivos e, ao mesmo tempo, a pluralidade das interpretações. (shrink)

Para Pablo, el acontecimiento pascual de Cristo supuso un momento esencial para la Historia. En la carta a los Gálatas, podemos percibir el enorme esfuerzo de construcción de un relato religioso sobre la base del diálogo de dos cosmovisiones: la judía y la helenisticorromana. En continuidad con el teocentrismo bíblico, Dios Creador es el protagonista absoluto de la historia y el cosmos. Desde la novedad cristológica y pragmática de su apostolado, la historia se convierte en un escenario orientado hacia la (...) participación de Cristo, bajo el impulso del Espíritu Santo, que se visibiliza en las pequeñas Iglesias cristianas.

Unlike with randomized controlled trials (RCTs) in clinical research, little has been said about the ethical principles that should regulate the use of RCTs in experimental development economics. One well-known principle in clinical research ethics is the principle of clinical equipoise. Some recent commentators suggest that an analogue of clinical equipoise should play a role in experimental development economics. In this article, I first highlight some difficulties with importing the concept to experimental development economics. I then argue that MacKay’s (2018, (...) 2020) notion of policy equipoise avoids these difficulties and has a role to play in experimental development economics. (shrink)

Ugar and Malele 1 critique the use of ‘generic’ technologies like artificial intelligence (AI) and machine learning (ML) for mental health diagnoses, particularly in sub-Saharan African countries. They highlight how these AI medical tools often overlook traditional perspectives and local contexts. The article has the merit of working on ethical issues regarding the particularities and risks of using AI and ML for health diagnosis in the Global South, an urgent and neglected topic. According to the authors, the use of these (...) AI technologies leads to overgeneralisation in diagnosing mental disorders, which could be especially problematic in the mental health field because of value-laden judgements intrinsic to the definition of mental health disorders. This argument is theoretically grounded in the hybrid conceptualisation of mental disorders proposed by Wakefield. 2 This author’s perspective incorporates both factual and value components in defining mental disorders, framing them as context-dependent ‘harmful dysfunctions’...

What is the fundamental insight behind truth-functionality ? When is a logic interpretable by way of a truth-functional semantics? To address such questions in a satisfactory way, a formal definition of truth-functionality from the point of view of abstract logics is clearly called for. As a matter of fact, such a definition has been available at least since the 70s, though to this day it still remains not very widely well-known. A clear distinction can be drawn between logics characterizable through: (...) (1) genuinely finite-valued truth-tabular semantics; (2) no finite-valued but only an infinite-valued truthtabular semantics; (3) no truth-tabular semantics at all. Any of those logics, however, can in principle be characterized through non-truth-functional valuation semantics, at least as soon as their associated consequence relations respect the usual tarskian postulates. So, paradoxical as that might seem at first, it turns out that truth-functional logics may be adequately characterized by non-truth-functional semantics . Now, what feature of a given logic would guarantee it to dwell in class (1) or in class (2), irrespective of its circumstantial semantic characterization? (shrink)

Although ethical decision‐making theory has evolved over the years, within the field of management, research still revolves around James Rest’s (1986) four‐step framework, dominated by a positivist epistemology and a quantitative methodology. Given that currently there is a call for a theoretical, epistemological, and methodological renovation for the enlargement and enrichment of knowledge about how decisions are morally made in organizations, this paper has a double aim. First, by showing the models’ main flaws and limitations, it critically assesses the prominent (...) theoretical models of Rest, Trevino, and Jones. Then, for decision making in organizations, the paper aims to posit a fresh moral theory that addresses the phenomenon from a comprehensive epistemological perspective. To do so, it steps back from those prominent models in order to review John Dewey’s “theory of moral life.” At the core of the proposed comprehensive theoretical framework are Dewey’s concepts of a “moral standard” and “valuation.” Finally, the paper shows how the Dewey‐based framework can both overcome the flaws and limitations that are identified in those prominent models and can enrich empirical research, therefore contributing to developing as a whole the ethical decision‐making field.

Humans have engaged in artistic and aesthetic activities since the appearance of our species. Our ancestors have decorated their bodies, tools, and utensils for over 100,000 years. The expression of meaning using color, line, sound, rhythm, or movement, among other means, constitutes a fundamental aspect of our species' biological and cultural heritage. Art and aesthetics, therefore, contribute to our species identity and distinguish it from its living and extinct relatives. Science is faced with the challenge of explaining the natural foundations (...) of such a unique trait, and the way cultural processes nurture it into magnificent expressions, historically and ethnically unique. How do the human mind and brain bring about these sorts of behaviors? What psychological and neural processes underlie the appreciation of painting, music, and dance? How does training modulate these processes? Are humans the only species capable of aesthetic appreciation, or are other species endowed with the rudiments of this capacity? Empirical examinations of such questions have a long and rich history in the discipline of psychology, the genesis of which can be traced back to the publication of Gustav Theodor Fechner's Vorschule der Aesthetik in 1876, making it the second oldest branch in experimental psychology. The Oxford Handbook of Empirical Aesthetics brings together leading experts in psychology, neuroimaging, art history, and philosophy to answer these questions. It provides the most comprehensive coverage of the domain of empirical aesthetics to date. With sections on visual art, dance, music, and many other art forms and aesthetic phenomena, the breadth of this volume's scope reflects the richness and variety of topics and methods currently used today by scientists to understand the way our mind and brain endow us with the faculty to produce and appreciate art and aesthetics.

We say that things happen accidentally when they do indeed happen, but only by chance. In the opposite situation, an essential happening is inescapable, its inevitability being the sine qua non for its very occurrence. This paper will investigate modal logics on a language tailored to talk about essential and accidental statements. Completeness of some among the weakest and the strongest such systems is attained. The weak expressibility of the classical propositional language enriched with the non-normal modal operators of essence (...) and accident is highlighted and illustrated, both with respect to the definability of the more usual modal operators as well as with respect to the characterizability of classes of frames. Several interesting problems and directions are left open for exploration. (shrink)

É corrente se afirmar que antes da Modernidade não há registro de mulheres na construção do pensamento erudito. Que, se tomarmos, po exemplo, a Filosofia e a Teologia, que foram as duas áreas do conhecimento que mais produziram intelectuais, durante a Idade Média, não encontraremos aí a presença de mulheres. Entretanto, apesar de todas as evidências, se vasculharmos a construção do Pensamento Ocidental, veremos que é possível identificar a presença de algumas mulheres já nos tempos remotos, na Antiguidade Clássica e (...) na Patrística (ou Alta Idade Média). Mas é na Escolástica (Baixa Idade Média) que encontramos as primeiras Pensadoras, responsáveis por um sistema autônomo, distinguindo-se como fecundas escritoras, donas de obras tão profundas e importantes quanto as produzidas pelos homens de seu tempo, com os quais muitas vezes dialogaram em pé de igualdade. Dentro desse maravilhoso universo feminino de intelectuais, destacamos, na Escolástica, a figura de Hildegarda de Bingen (1098-1165), da qual trataremos um pouco neste artigo. It is common to say that before modernity there is no record of women in the construction of classical thought. What if we take, for example, to philosophy and theology, which were the two areas of knowledge that produced more intellectuals during the Middle Ages, we find there the presence of women. However, despite all the evidence, if we search the construction of Western Thought, we see that it is possible to identify the presence of some women already in ancient times, in Classical Antiquity and Patristics (or Middle Ages). But it is in Scholastic (Middle Ages) we find the first thinkers, responsible for an autonomous system, especially as fertile writers, owners of works so profound and important as those produced by men of his time, who often conversed on an equal footing. In this wonderful universe of female intellectuals, highlight, in Scholastic, the figure of Idelgarda of Bingen (1098-1165), which is discussed a bit in this article. (shrink)

Os Objetivos de Desenvolvimento Sustentável (ODS) abrangem diversas questões socioambientais e são aplicáveis a todos os países. O ODS 15, Vida Terrestre, visa proteger os ecossistemas terrestres, conservar a biodiversidade e reduzir a perda de biodiversidade, e o estado do Paraná é um dos estados com uma das maiores proporções de área de remanescentes florestais do Brasil e conta com uma política de preservação ambiental. Em vista disso, o estudo tem como objetivo analisar a eficiência dos municípios paranaenses no atendimento (...) ao Objetivo do Desenvolvimento Sustentável 15 - Proteger a vida terrestre. Para isso, foi utilizada a abordagem da Análise Envoltória de Dados (DEA – Data Envelopment Analysis), tendo como input o Imposto sobre Circulação de Mercadorias e Serviços Ecológico (ICMS Ecológico) e como output o percentual de áreas florestais dos municípios. Os resultados apontaram que os municípios Campo do Tenente, Céu Azul, Guaratuba, Imbituva, Ipiranga, Mirador, Morretes e Teixeira Soares foram eficientes, tendo como característica principal, a presença de parques ecológicos. Por outro lado, foi observado que as regiões mais industrializadas e urbanas concentraram mais municípios com ineficiência forte. Além disso, os municípios Piraquara, Pinhais, Campo Magro e Quatro Barras apresentaram os maiores excessos no recebimento de recursos do ICMS Ecológico. Enquanto os municípios de Pinhais, Curitiba, São Jorge do Patrocínio, Altônia, São Pedro do Paraná e Quatiguá apresentaram as maiores necessidades relativas de aumentar as áreas remanescentes florestais.

Genetic engineering has been a topic of discussion for over 50 years, but it is only recently that gene editing has become a reality. CRISPR biotechnologies have made gene editing much safer, precise and feasible. We have witnessed the first cases of human germline genetic modification resulting in live births, conducted by He Jiankui. In this paper, we will analyse He Jiankui’s case in relation to one of the most difficult problems in procreative ethics (or the ethics of future generations): (...) the non‐identity problem. We believe that this analysis will help us to understand the ethics involved in gene editing and hopefully allow for a better, more philosophically grounded legislation on CRISPR and other gene‐editing technologies.

This paper employs structural topic modeling (STM) to describe the academic philosophy landscape in Brazil. Based on a public national database, a corpus consisting of 12,515 abstracts of monographs defended in philosophy graduate programs between 1991 and 2021 was compiled. The final STM model identified 74 meaningful research topics, clustered into 7 thematic categories. This study discusses the prevalence of the most significant topics and categories, their trends across three decades, and their (positive or negative) association with the supervisor's gender. (...) Results show the first empirical evidence that Brazilian philosophical research exhibits a greater focus on philosophers than on specific themes or problems. Moreover, by visualizing the variations in topic prevalence over time, it was possible to track the rise or decline of the major interest categories and topics. Finally, results also show which topics are more influenced or less influenced by gender. (shrink)

In classical logic, a contradiction allows one to derive every other sentence of the underlying language; paraconsistent logics came relatively recently to subvert this explosive principle, by allowing for the subsistence of contradictory yet non-trivial theories. Therefore our surprise to find Wittgenstein, already at the 1930s, in comments and lectures delivered on the foundations of mathematics, as well as in other writings, counseling a certain tolerance on what concerns the presence of contradictions in a mathematical system. ‘Contradiction. Why just this (...) spectre? This is really very suspicious.’ ( Philosophical Remarks III–56) In the last decades, several authors (e.g. Arrington, Hintikka, Van Heijenoort, Wright, Wrigley) have been digging into Wittgenstein’s rather non-standard standpoint on what concerns the interpretation and import of contradiction in logic and mathematics, and many other authors (e.g. da Costa, Goldstein, Granger, Marconi) have been investigating the possibility of taking Wittgenstein seriously as one of the early forerunners of paraconsistency. While many advances have been made on the first front, the second set of investigations has led almost exclusively to negative results: no, no operational proposal about the construction of a logic in which (some) contradictions are made inoffensive can be read from Wittgenstein’s philosophical work; in fact, it appears that the most one can find there is the exhortation for mathematicians to alter their attitude with respect to contradictions and to consistency proofs. The play is done, and one looks for a resume of the opera. This paper fills that blank, as a thorough investigation of the possible relations between Wittgenstein and paraconsistency.

The First International and Interdisciplinary Conference on Modelling and Using Context, Rio de Janeiro, January 1997, gave rise to the present book, which contains a selection of the papers presented there, thoroughly refereed and revised. The treatment of contexts as bona fide objects of logical formalisation has gained wide acceptance, following the seminal impetus given by McCarthy in his Turing Award address. The field of natural language offers a particularly rich variety of examples and challenges to researchers concerned with the (...) formal modelling of context, and several chapters in the volume deal with contextualisation in the setting of natural language. Others adopt a purely formal-logical viewpoint, seeking to develop general models of even wider applicability. The 12 chapters are organised in three groups: formalisation of contextual information in natural language understanding and generation, the application of context in mechanised reasoning domains, and novel non-classical logics for contextual application.

Baseado no princípio ontológico da vera justitia, ou da “divina ordem”, segundo a qual é justo que se “subordinem as coisas somente às dignas, as corporais às espirituais, as inferiores às superiores, as temporais às sempiternas” (Ep., 140), o que resulta, na prática, na subordinação dos governados aos governantes, Agostinho introduz em sua doutrina ético-política o conceito de força coercitiva, como instrumento prático garantidor da ordinata concordia ou pax temporalis, na civitas, de forma que, punido pelo reto castigo, o pecador (...) possa retornar à ordem e assim alcançar a vida eterna. Em Agostinho, todas as formas de castigos por ele admitidos não têm um caráter de perseguição, vingança ou sadismo, mas de correção e reintegração do pecador na ordem, por isso devem ser guiados pela caridade. PALAVRAS-CHAVE – Força coercitiva. Castigo. Justiça. Ordem. Paz. Caridade. ABSTRACT With basis on the ontological principle of Vera justitia, or of “divine order”, according to which it is fair to “subordinate things only to the worthy ones, the corporal to the spiritual, the inferior to the superior, the temporal to the sempiternal” (Ep. 140), this results, in practice, in the subordination of the governees to the governators, Augustine introduces in his ethical-political doctrine the concept of coercitive force, as the practical instrument that warrants the ordinata concordia or pax temporalis, in civitas, in such a manner, that punished by the straight punishment, the sinner may return to order and so reach eternal life. In Augustine, all forms of punishment by him admitted do not take a character of persecution, revenge or sadism, but of correction and reintegration of the sinner in the order, and, for this reason, punishment must be guided by charity. KEY WORDS – Coercitive force. Punishment. Justice. Peace. Charity. (shrink)

In this article, I address a controversial aspect of Rawls’s treatment of the question of justice between generations: how the parties in the original position could be motivated to select Rawls’s preferred principle of intergenerational savings, which he dubs the just savings principle. I focus on the explanation found in his later work, where he proposes that the correct savings principle is the principle that any generation would have wanted preceding generations to have followed. By expanding upon this explanation, I (...) respond to the objection that this explanation disregards the perspective of the first generation. I demonstrate that this objection ceases to be a concern when a proper account of the parties’ reasoning is developed. What is notable about the explanation I defend is that it relies on the parties adopting maximax – not maximin – as a rule for rational decision making. Having established this intermediary conclusion, I depart with Rawls and consider what savings principle the parties would choose if given more options. Ultimately, I argue that the parties would select a principle that Rawls would have undoubtedly rejected if presented to him at face value. This is because the principle of savings I argue would be selected requires continual economic growth over generations to increase upwards indefinitely – a conclusion Rawls is explicitly trying to avoid in his theory of justice.

In many real-life applications of logic it is useful to interpret a particular sentence as true together with its negation. If we are talking about classical logic, this situation would force all other sentences to be equally interpreted as true. Paraconsistent logics are exactly those logics that escape this explosive effect of the presence of inconsistencies and allow for sensible reasoning still to take effect. To provide reasonably intuitive semantics for paraconsistent logics has traditionally proven to be a challenge. Possible-translations (...) semantics can meet that challenge by allowing for each interpretation to be composed of multiple scenarios. Using that idea, a logic with a complex semantic behavior can be understood as an appropriate combination of ingredient logics with simpler semantic behaviors into which the original logic is given a collection of translations preserving its soundness. Completeness is then achieved through the judicious choice of the admissible translating mappings. The present note provides interpretation by way of possible-translations semantics for a group of fundamental paraconsistent logics extending the positive fragment of classical propositional logic. The logics PI, Cmin, mbC, bC, mCi and Ci, among others, are all initially presented through their non-truth-functional bivaluation semantics and sequent versions and then split by way of possible-translations semantics based on 3-valued ingredients.

In this paper I challenge the pernicious aspects of Milton Friedman's methodological outlook that continues to hold sway over mainstream neoclassical economists. I do this by showing how Friedman's own methodological dicta could have been used against him when he famously advanced the expectations critique of the Phillips curve at his presidential address to the American Economic Association. I use this case study to further suggest that psychological and neurophysiological data should not be deemed irrelevant to economic science.

Descartes é reconhecido como o fundador da filosofia do sujeito e das representações. É através do cogito que o sujeito expressa a constatação de sua existência, e é através das representações que as outras coisas são pensadas por este sujeito. Este artigo pretende desenvolver uma análise sobre a constituição do cogito, com a finalidade de refletir se o cogito pode ser pensado como representação. Para tanto, abordaremos duas linhas interpretativas: uma tendo em Heidegger seu expoente e a outra em Ferdinand (...) Alquié. Referências ao cogito como representação podem ser encontradas com certa naturalidade na literatura crítica de Descartes. Pretendemos analisar se esta “naturalidade” consiste em uma interpretação adequada do cogito cartesiano. (shrink)

Nas páginas finais das Segundas Respostas, Descartes fala sobre a maneira pela qual as teses apresentadas nas Meditações Metafísicas são demonstradas e sobre o estilo de escrita por ele adotado para esta obra. A maneira de demonstrar é a análise; o estilo de escrita é a meditação. A leitura das Meditações depende, fundamentalmente, do entendimento sobre essas duas coisas, bem como sobre a relação existente entre elas. Com o presente artigo pretendemos, em primeiro lugar, analisar o modo como Descartes entende (...) o método de análise e o significado de meditação; e, em seguida, compreender a maneira pela qual o método de análise e o exercício da meditação se articulam para constituir a via seguida nas Meditações Metafísicas. Considerando a análise como um método de resolução de problemas, bem como o significado do estilo de escrita meditativo nos tempos de Descartes, defendemos a tese de que que meditar, para Descartes, significa penetrar-se lentamente e com atenção nos problemas a partir dos quais as Meditações são desenvolvidas.

An overcomplete logic is a logic that ‘ceases to make the difference’: According to such a logic, all inferences hold independently of the nature of the statements involved. A negation-inconsistent logic is a logic having at least one model that satisfies both some statement and its negation. A negation-incomplete logic has at least one model according to which neither some statement nor its negation are satisfied. Paraconsistent logics are negation-inconsistent yet non-overcomplete; paracomplete logics are negation-incomplete yet non-overcomplete. A paranormal logic (...) is simply a logic that is both paraconsistent and paracomplete. -/- Despite being perfectly consistent and complete with respect to classical negation, nearly every normal modal logic, in its ordinary language and interpretation, admits to some latent paranormality: It is paracomplete with respect to a negation defined as an impossibility operator, and paraconsistent with respect to a negation defined as non-necessity. In fact, as it will be shown here, even in languages without a primitive classical negation, normal modal logics can often be alternatively characterized directly by way of their paranormal negations and related operators. So, instead of talking about ‘necessity’, ‘possibility’, and so on, modal logics could be seen just as devices tailored for the study of (modal) negation. This paper shows how and to what extent this alternative characterization of modal logics can be realized. (shrink)

This edited volume explores the different and seminal ways colours matter to philosophy. Each chapter provides an insightful analysis of one or more cases in which colours raise philosophical problems in different areas and periods of philosophy. This historically informed discussion examines both logical and linguistic aspects, covering such areas as the mind, aesthetics and the foundations of mathematics. The international contributors look at traditional epistemological and metaphysical issues on the subjectivity and objectivity of colours. In addition, they also assess (...) phenomenological problems typical of the continental tradition and contemporary problems in the philosophy of mind. The chapters include coverage of such topics as Newton’s and Goethe’s theory of light and colours, how primary qualities are qualitative and colours are primary, explaining colour phenomenology, and colour in cognition, language and philosophy. "This book beautifully prepares the ground for the next steps in our research on and philosophising about colour" Daniel D. Hutto "It is not an overstatement to say that How Colours to Philosophy is a ground breaking publication" Mazviita Chirimuuta "Anyone interested in philosophical issues about color will find it highly stimulating." Martine Nida-Rümelin "The high quality papers included in this anthology succeed admirably in enriching current philosophical thinking about colour” Erik Myin “This is certainly the most complete collection of philosophical essays on colours ever published” André Leclerc “All in all this collections represents a new milestone in the ongoing philosophical debate on colours and colour expressions” Ingolf Max.

A central feature of experimental development economics is the use of randomized controlled trials (RCTs) to evaluate the effectiveness of prospective socioeconomic interventions. The use of RCTs in development economics raises a host of ethical issues which are just beginning to be explored. In this article, I address one ethical issue in particular: the routine use of the status quo as a control when designing and conducting a development RCT. Drawing on the literature on the principle of standard care in (...) medical research ethics, as well as considerations of distributive justice in non-ideal circumstances, I argue that the practice of using the status quo as a control is ethically justifiable. However, I add an important qualification based on the natural duty of rescue to address the concern that my account is overly permissive. (shrink)

Communication campaigns often highlight environmental progress to encourage further pro-environmental behaviour. Consequently, the drop in carbon emissions caused by the COVID-19 restrictions has been framed as a positive environmental outcome of the pandemic. We conducted an experimental study with a US-representative sample (N = 500) to show that raising awareness of emissions reduction has the contrary effect: an increase in moral self-concept facilitated a negative spillover, namely, it reduced climate-friendly behavioural intentions. Normative influence was able to prevent this negative spillover (...) because activating environmental norms inhibited compensatory feelings. Besides, awareness of recent emissions reduction was less likely to increase the moral self-concept of participants with a strong environmental self-identity. Our findings demonstrate that environmental progress increases moral self-concept which, in turn, could cause a negative spillover (i.e., reduce climate-friendly low-carbon behaviour and increase climate-harmful high-carbon behaviour). Normative influences and environmental self-identity can inhibit this negative spillover. (shrink)

Esse texto procura estabelecer a conexão entre o opúsculo “Sobre o primeiro fundamento da distinção de direções no espaço” (GUGR), de 1768, e a Crítica da razão pura (KrV), de 1781, procurando evidenciar que há um programa de pesquisa de Kant sobre a estrutura do espaço que principia com as reflexões estabelecidas a partir das contrapartidas incongruentes. Para defender esse argumento, há uma grande dificuldade, pois Kant não se reporta às contrapartidas incongruentes no texto da primeira crítica. São vários os (...) comentadores que se reportam a esse fato para minorar a importância do texto de 1768 para a constituição da estética teórica. Para caracterizar a importância das contrapartidas incongruentes para o pensamento crítico, procuraremos examinar uma tese do espaço exposta nos Prolegômenos a toda a metafísica futura (Prol), de 1783, que é a de que somente o todo é fundamento de possibilidade das partes. Se os Prolegômenos fazem o caminho invertido, o do método analítico, e a Crítica da razão pura percorre o caminho sintético, quais seriam, nesse caso, as condições de possibilidade de uma estética que deveria ser construída a priori? Ao analisar essa questão, procuraremos mostrar que a sua solução depende das contrapartidas incongruentes nos Prolegômenos, e que ela é igualmente decisiva para a construção da Estética Transcendental. Com essa estratégia, procuraremos mostrar que há pressupostos epistemológicos em comum entre os três textos. Palavras-chave: Kant. Contrapartidas incongruentes. Espaço. Geometria. Parte. Todo. Infinitude and mereology in the construction of Kant’s theoretical aesthetics Abstract: The aim of this text is to establish the connection between the 1768 essay “Concerning the ultimate ground of the differentiation of directions in space” (GUGR) and the 1781 Critique of Pure Reason (KrV), seeking to show that Kant has a research program regarding the structure of space that begins with reflections established from incongruent counterparts. There is considerable difficulty in defending this argument, because Kant does not refer to incongruent counterparts in the text of the first critique. Several commentators have referred to this fact to downplay the importance of the 1768 text for constituting theoretical aesthetics. To characterize the importance of incongruent counterparts for critical thinking, we examine a thesis on space presented in the Prolegomena To Any Future Metaphysics (Prol), of 1783, which is that only the whole is the ground for the possibility of the parts. If the Prolegomena take the opposite route, that of the analytical method, and the Critique of Pure Reason follows the synthetic route, what, in this case, would be the conditions for the possibility of an aesthetic that should be constructed a priori? In analyzing this question, we seek to show that its solution depends on the incongruent counterparts in the Prolegomena, and that it is equally decisive for constructing Transcendental Aesthetics. Using this strategy, we seek to show that the three texts have epistemological assumptions in common. Keywords: Kant. Incongruent counterparts. Space. Geometry. Part. Whole. Infinitud y mereología en la construcción de la estética teórica de Kant Resumen: El presente texto busca establecer la conéxion entre el opúsculo “Sobre el fundamento primero de la diferencia entre las regiones del espacio” (GUGR), de 1768, y la Crítica de la razón pura (KrV), de 1781, intentando evidenciar que hay un programa de investigación de Kant sobre la estructura del espacio que empieza con las reflexiones establecidas a partir de las contrapartidas incongruentes. Para defender ese argumento, hay una gran dificultad, pues Kant no se reporta a las contrapartidas incongruentes en el texto de la primera crítica. Son varios los comentadores que se reportan a ese hecho para minimizar la importancia del texto de 1768 para la constitución de la estética teórica. Para caracterizar la importancia de las contrapartidas incongruentes para el pensamiento crítico, procuraremos examinar una tesis del espacio expuesta en los Prolegómenos a toda metafísica futura (Prol), de 1783, que es de que solamente el todo es fundamento de posibilidad de las partes. Se los Prolegómenos hacen el camino invertido, del método analítico, y la Crítica de la razón pura recorre el camino sintético, ¿cuales serían, en ese caso, las condiciones de posibilidad de una estética que debería ser construida a priori? Al analizar esa cuestión, procuraremos mostrar que su solución depende de las contrapartidas incongruentes en los Prolegómenos, y que ella es igualmente decisiva para la construcción de la Estética Transcendental. Con esa estratégia, esforzaremos en mostrar que hay presupuestos epistemológicos en común entre los tres textos. Palavras clave: Kant. Contrapartes incongruentes. Espacio. Geometría. Parte. Todo.

This article offers the results of emergy analysis used to evaluate four different soybean production systems in Brazil that were divided into two main categories: biological models (organic and ecological farms) and industrial models (green-revolution chemical farms and herbicide with no-tillage farms). The biological models show better environmental, economical, and social performance indicators; however, at the national level, discussion of transgenic soybean seed release considers only industrial models without any mention of biological models. Classic emergy analysis shows biological options are (...) the better alternatives but does not explain why decisions taken by farmers and government in Brazil were in opposition to these options. New research is proposed to identify and quantify the external forces that strongly interfere in the definition of public policy for soybean production. New parameters are proposed to enrich emergy methodology: Renewability of each input was considered in emergy calculations and negative externalities were included as additional services. (shrink)

O presente trabalho tem como objetivo central indicar alguns pontos de aproximação e distinção entre o sentido atribuído por Kierkegaard à angústia na obra O conceito de angústia, e o modo pelo qual Heidegger aborda tal conceito no âmbito da analítica existencial desenvolvida em Ser e tempo. Muito embora seja possível apontar inegáveis semelhanças no modo pelo qual os dois autores compreendem o fenômeno da angústia, algumas distinções podem ser feitas se analisados os contextos a partir dos quais os pensadores (...) se ocuparam do tema em questão. Enquanto que para Kierkegaard a angústia é vista em estrita relação com o pecado, a fé e a liberdade, Heidegger busca atribuir ao fenômeno do angustiar-se um sentido ontológico, inscrito no projeto da ontologia fundamental, a partir do qual torna-se possível ao Dasein ser livre para escolher a si mesmo, e assim assumir o modo próprio de ser.

O presente artigo tem como objetivo justificar que a concepção de ética originária desenvolvida por Heidegger, alinhada à importância que Gadamer atribui à experiência particular, pode trazer uma relevante contribuição para a reflexão filosófica acerca dos temas que envolvem a ética, como tentativa de superação do modo tradicional de se conceber a própria ética enquanto tal. A forma pela qual a tradição metafísica tem historicamente abordado o tema da ética reforça a distinção entre teoria e prática, e a busca de (...) princípios ou normas universalmente aplicáveis tem se mostrado insuficiente para elucidar o que torna possível a experiência moral. A linguagem conceitual generalista, da mesma forma, tem se demonstrado inadequada para tratar do tema, visto que tende a aproximar a ética da técnica própria das ciências, ignorando a relevância que a experiência particular pode trazer para o debate ético. Nesta perspectiva, a ética originária fornece elementos para a construção de um sentido de ética que almeja alcançar a singularidade da existência, superando assim a distinção entre teoria e prática, e colocando em evidência uma instância prévia, que permaneceu oculta em razão dos limites da própria metafísica.

Scientific research in the formal sciences comes in multiple degrees of formality: fully formal work; rigorous proofs that practitioners know to be formalizable in principle; and informal work like rough proof sketches and considerations about the advantages and disadvantages of various formal systems. This informal work includes informal and semi-formal debates between formal scientists, e.g. about the acceptability of foundational principles and proposed axiomatizations. In this paper, we propose to use the methodology of structured argumentation theory to produce a formal (...) model of such informal and semi-formal debates in the formal sciences. For this purpose, we propose ASPIC-END, an adaptation of the structured argumentation framework ASPIC+ which can incorporate natural deduction style arguments and explanations. We illustrate the applicability of the framework to debates in the formal sciences by presenting a simple model of some arguments about proposed solutions to the Liar paradox, and by discussing a more extensive—but still preliminary—model of parts of the debate that mathematicians had about the Axiom of Choice in the early twentieth century.
