La visión tradicional del pensamiento crítico (PC) fundada en un enfoque racionalista ha sido puesta en duda a partir de fines del siglo pasado por la ‘segunda ola’ del PC, la cual, a pesar de no ser un movimiento del todo definido, ha incluido aspectos como la imaginación, la creatividad y el trabajo cooperativo en su comprensión y en su aplicación a la enseñanza. Paralelamente, perspectivas actuales en psicología moral como el modelo ‘intuicionista social’ propuesto por Jonathan Haidt, representan un (...) desafío al modelo racionalista de la moral que suponen gran parte de las éticas normativas canónicas. Siendo que tanto el PC como el fundamento moral representan factores fundamentales en la enseñanza de ética, se hace explicito que esta última precisa también ser revisada. Es por ello que el presente trabajo analiza una perspectiva del PC alternativa a la tradicional basada en el potencial aporte de la metacognición y del modelo intuicionista social, con el fin de abrir nuevas vías de investigación para la actualización del fundamento moral que se supone en la enseñanza de ética. Para ahondar en ello, se ejemplificará la relevancia y aplicabilidad de la metacognición en la enseñanza de ética con situaciones vinculadas a la actual pandemia por Covid-19. (shrink)

Neste artigo pretendemos discutir o conceito de consciência na perspectiva de John Searle analisando seu pensamento filosófico acerca deste conceito. Para isso, analisamos uma obra de Searle intitulada Consciência e Linguagem, na qual Searle retrata aspectos interessantes sobre a consciência, sobretudo nos três primeiros capítulos. Talvez o grande problema do estudo da consciência seja a tarefa conceitual, pois são vinte cinco séculos de tentativas sem que cheguemos a um conceito “universal” de consciência. Para Searle não é difícil delimitarmos consciência: consciência (...) é o conjunto de estado subjetivos de sensibilidade (sentience) ou ciência (awareness), que se iniciam quando uma pessoa acorda, e que se estendem ao longo do dia. No decorrer das discussões, Searle nos traz um problema, a saber: Como estudar a consciência cientificamente? Com esta indagação, Searle vai retratar o conceito de objetividade cientifica em face do conceito de subjetivo, que é por vezes excluído do estudo cientifico. Assim, entender algumas características da consciência se torna tarefa de suma importância, na medida em que são essenciais para a existência da consciência; estas características são: a subjetividade, a qualidade e a unidade. Claro que concepção de Searle não é universalmente aceita na academia cientifica; entretanto suas indagações nos mostram um caminho “seguro” a partir do qual a ciência pode trilhar um estudo filosófico-cientifico da consciência.

The role of academic satisfaction on persistence and successful academic behavior has been the focus of research for decades. Nevertheless, driven by positive educational psychology, subjective well-being has been highlighted as another central feature in the academic path of students. Studies aimed at identifying the variables that contribute to explain different aspects of academic performance have been widely investigated, although studies aimed at identifying the determinants of subjective well-being are still limited. The present paper examined the contribution of AS judgments (...) on subjective well-being. To this end, it was hypothesized that SWB levels depend on the balance between positive/negative emotions and life satisfaction judgments. Furthermore, it was stipulated that AS has an indirect contribution on SWB, through life satisfaction, whereas the balance of emotions influences both AS judgments and life satisfaction. Using an analysis strategy based on structural equation modeling, the results indicated that the model fitted satisfactorily, explaining 32% of the variance of SWB. Particularly, it was observed that AS judgments contributed to life satisfaction judgments. Although no direct contribution of AS on SWB was reported, a total contribution partially mediated by life satisfaction judgments was revealed. These findings support the importance of academic satisfaction judgments, not only because of their importance in academic terms, but also because of their impact on university students’ subjective well-being and health.

In this work we present a dynamical approach to quantum logics. By changing the standard formalism of quantum mechanics to allow non-Hermitian operators as generators of time evolution, we address the question of how can logics evolve in time. In this way, we describe formally how a non-Boolean algebra may become a Boolean one under certain conditions. We present some simple models which illustrate this transition and develop a new quantum logical formalism based in complex spectral resolutions, a notion that (...) we introduce in order to cope with the temporal aspect of the logical structure of quantum theory.

Robustness is a significant constraint in machine learning models. The performance of the algorithms must not deteriorate when training and testing with slightly different data. Deep neural network models achieve awe-inspiring results in a wide range of applications of computer vision. Still, in the presence of noise or region occlusion, some models exhibit inaccurate performance even with data handled in training. Besides, some experiments suggest deep learning models sometimes use incorrect parts of the input information to perform inference. Active image (...) augmentation is an augmentation method that uses interpretability methods to augment the training data and improve its robustness to face the described problems. Although ADA presented interesting results, its original version only used the vanilla backpropagation interpretability to train the U-Net model. In this work, we propose an extensive experimental analysis of the interpretability method’s impact on ADA. We use five interpretability methods: vanilla backpropagation, guided backpropagation, gradient-weighted class activation mapping, guided GradCam and InputXGradient. The results show that all methods achieve similar performance at the ending of training, but when combining ADA with GradCam, the U-Net model presented an impressive fast convergence. (shrink)

RESUMEN El diálogo propuesto entre Heidegger y Adorno, especificamente en lo que concierne a las ideas de crítica y de resistencia, no desconoce la importancia que adquiere para el último la crítica extensa que él mismo dirige a la ontología de Heidegger, ni para este su cuestionamiento de la filosofia dialéctica. El artículo busca mostrar que, en ambos autores, la idea de crítica y de resistencia se resuelve como indagación del sentido negativo de la experiencia. Se concluye que, destacando semejanzas (...) y diferencias en sus planteamientos, la reivindicación del carácter negativo de la experiencia equivale reivindicar el poder crítico de la filosofia y del arte. ABSTRACT The dialogue between these two authors, concerning specifically the ideas of critique and resistance, does not ignore the importance attributed by Adorno to the extensive critique that himself addresses to Heidegger's ontology, nor the one attributed by the latter to his questioning of the dialectical philosophy. The paper shows that in both authors the ideas of critique and resistance can be settled as an inquiry into the negative sense of experience. It is concluded that, highlighting similarities and differences in their approaches, the recognition of the negative trait of experience equals to claiming the critical power of philosophy and art.

A chamada Síntese Evolutiva (SE), formulada entre os anos 1920 e 1940, constitui o quadro interpretativo dominante na biologia evolutiva atual. A proposta mais bem articulada, teórica e institucionalmente, de uma mudança nesse quadro, denomina-se Síntese Evolutiva Estendida (SEE). Nosso principal objetivo será apresentar e desenvolver as seguintes objeções à SEE: (I) apesar de se declarar como uma “extensão” da SE, a SEE reinterpreta processos evolutivos, reformula sua rede conceitual e modifica pressupostos centrais da SE. Portanto, a diferença entre SEE (...) e SE não deveria ser descrita como uma relação conjunto-subconjunto (isto é, como uma “extensão”); (II) apesar de se declarar como uma “síntese”, a SEE leva, pelo menos em curto prazo, a um pluralismo de abordagens na biologia evolutiva. Portanto, a SEE não deveria ser descrita como uma síntese, mas como um quadro interpretativo amplo e plural que abarca diferentes abordagens. Essas objeções não são direcionadas às mudanças propostas, mas à interpretação dessas mudanças como uma “síntese estendida” do quadro evolutivo anterior. Com base nessas objeções, formularemos três hipóteses para explicar o uso do termo “síntese estendida” entre os seus proponentes. (shrink)

Palabras de agradecimiento al promotor del Congreso Internacional y a los participantes en él. Asimismo, a la persona que ha trabajado en la labor de transcripción de mis escritos y a otros colaboradores míos.

This work presents an overview of Brazil’s scientific heritage, especially the collections and sets of artefacts related to the exact sciences and engineering. The information provided is the outcome of a survey being undertaken on a national level under the coordination of Museu de Astronomia e Ciências Afins, which is leading teams from five Brazilian universities. Sets of objects have been identified at museums, universities, military establishments, and some secondary schools. The best preserved collections are at a few museums, but (...) the universities hold most of the artefacts. The overwhelming majority of the objects were made in the twentieth century, primarily the second half. After the general results of the survey are presented, details about a few sets of objects and collections are given, including information about their current state, the provenance of the objects and the history of the institutions. The objective of this initiative is to raise the awareness of the Brazilian state so that a policy is created for preserving this heritage and financing mechanisms to assure it can be researched, conserved, and ultimately fulfil its mission in society.

Living organisms act as integrated wholes to maintain themselves. Individual actions can each be explained by characterizing the mechanisms that perform the activity. But these alone do not explain how various activities are coordinated and performed versatilely. We argue that this depends on a specific type of mechanism, a control mechanism. We develop an account of control by examining several extensively studied control mechanisms operative in the bacterium E. coli. On our analysis, what distinguishes a control mechanism from other mechanisms (...) is that it relies on measuring one or more variables, which results in setting constraints in the control mechanism that determine its action on flexible constraints in other mechanisms. In the most basic arrangement, the measurement process directly determines the action of the control mechanism, but in more complex arrangements signals mediate between measurements and effectors. This opens the possibility of multiple responses to the same measurement and responses based on multiple measurements. It also allows crosstalk, resulting in networks of control mechanisms. Such networks integrate the behaviors of the organism but also present a challenge in tailoring responses to particular measurements. We discuss how integrated activity can still result in differential, versatile, responses. (shrink)

The new mechanists and the autonomy approach both aim to account for how biological phenomena are explained. One identifies appeals to how components of a mechanism are organized so that their activities produce a phenomenon. The other directs attention towards the whole organism and focuses on how it achieves self-maintenance. This paper discusses challenges each confronts and how each could benefit from collaboration with the other: the new mechanistic framework can gain by taking into account what happens outside individual mechanisms, (...) while the autonomy approach can ground itself in biological research into how the actual components constituting an autonomous system interact and contribute in different ways to realize and maintain the system. To press the case that these two traditions should be constructively integrated we describe how three recent developments in the autonomy tradition together provide a bridge between the two traditions: (1) a framework of work and constraints, (2) a conception of function grounded in the organization of an autonomous system, and (3) a focus on control.

In this pathbreaking study, Micaela di Leonardo reveals the face of power within the mask of cultural difference. From the 1893 World's Fair to Body Shop advertisements, di Leonardo focuses on the intimate and shifting relations between popular portrayals of exotic Others and the practice of anthropology. In so doing, she casts new light on gender, race, and the public sphere in America's past and present. "An impressive work of scholarship that is mordantly witty, passionately argued, and takes (...) no prisoners."--Lesley Gill, News Politics "[Micaela] di Leonardo eloquently argues for the importance of empirical, interdisciplinary social science in addressing the tragedy that is urban America at the end of the century."--Jonathan Spencer, Times Literary Supplement "In her quirky new contribution to the American culture brawl, feminist anthropologist Micaela di Leonardo explains how anthropologists, 'technicians of the sacred,' have distorted American popular debate and social life."--Rachel Mattson, Voice Literary Supplement "At the end of di Leonardo's analyses one is struck by her rare combination of rigor and passion. Simply, [she] is a marvelous iconoclast."--Matthew T. McGuire, Boston Book Review. (shrink)

Resumo Este artigo procura apresentar e discutir tentativas recentes em filosofia social de analisar e interpretar o capitalismo, a partir de uma perspectiva praxeológica. O practice turn em teoria social procurou superar o dualismo entre agência e estrutura, ou entre ação e sistema, por meio da noção de prática social. Seria possível então interpretar o capitalismo como um tipo especifico de prática social? Para tentar encaminhar essa questão, explicita-se brevemente, em um primeiro momento, em que consiste o practice turn em (...) teoria social. Num segundo momento, analisa-se e se discute a proposta de Rahel Jaeggi de conceber a economia como uma rede de práticas sociais. Em seguida, expõe-se e se avalia a tentativa de Christian Lotz em ver, no dinheiro, a chave para compreender aquilo que ele chama de esquema capitalista. Por fim, conclui-se, chamando a atenção para os potenciais e desafios ligados ao empreendimento de interpretar o capitalismo em função de uma teoria da prática, sugerindo que um aprofundamento na análise da imaginação especificamente capitalista, vinculando-a com a típica plasticidade e diversidade do capitalismo, possa ajudar a avançar nesse campo.This paper aims to present and discuss recent attempts in social philosophy to analyze and interpret capitalism from a praxeological perspective. The practice turn in social theory sought to overcome the dualism between agency and structure, or between action and system, through the notion of social practice. Is it then possible to interpret capitalism as a specific type of social practice? To try to address this question, I briefly introduce, in a first moment, the practice turn in social theory. In a second moment, I analyze and discuss Rahel Jaeggi’s proposal to conceive the economy as a network of social practices. I then explain and evaluate Christian Lotz’s attempt to see money as the key to understanding what he names as “the capitalist schema”. Finally, I conclude by drawing attention to the potentials and challenges of interpreting capitalism as a social practice, suggesting that a deeper analysis of specifically capitalist imagination, linking it with the typical plasticity and diversity of capitalism, may help to move forward in this field.

Biological regulation is what allows an organism to handle the effects of a perturbation, modulating its own constitutive dynamics in response to particular changes in internal and external conditions. With the central focus of analysis on the case of minimal living systems, we argue that regulation consists in a specific form of second-order control, exerted over the core regime of production and maintenance of the components that actually put together the organism. The main argument is that regulation requires a distinctive (...) architecture of functional relationships, and specifically the action of a dedicated subsystem whose activity is dynamically decoupled from that of the constitutive regime. We distinguish between two major ways in which control mechanisms contribute to the maintenance of a biological organisation in response to internal and external perturbations: dynamic stability and regulation. Based on this distinction an explicit definition and a set of organisational requirements for regulation are provided, and thoroughly illustrated through the examples of bacterial chemotaxis and the lac-operon. The analysis enables us to mark out the differences between regulation and closely related concepts such as feedback, robustness and homeostasis. (shrink)

Organization figures centrally in the understanding of biological systems advanced by both new mechanists and proponents of the autonomy framework. The new mechanists focus on how components of mechanisms are organized to produce a phenomenon and emphasize productive continuity between these components. The autonomy framework focuses on how the components of a biological system are organized in such a way that they contribute to the maintenance of the organisms that produce them. In this paper we analyze and compare these two (...) accounts of organization and argue that understanding biological organisms as cohesively integrated systems benefits from insights from both. To bring together the two accounts, we focus on the notions of control and regulation as bridge concepts. We start from a characterization of biological mechanisms in terms of constraints and focus on a specific type of mechanism, control mechanisms, that operate on other mechanisms on the basis of measurements of variables in the system and its environment. Control mechanisms are characterized by their own set of constraints that enable them to sense conditions, convey signals, and effect changes on constraints in the controlled mechanism. They thereby allow living organisms to adapt to internal and external variations and to coordinate their parts in such a manner as to maintain viability. Because living organisms contain a vast number of control mechanisms, a central challenge is to understand how they are themselves organized. With the support of examples from both unicellular and multicellular systems we argue that control mechanisms are organized heterarchically, and we discuss how this type of control architecture can, without invoking top-down and centralized forms of organizations, succeed in coordinating internal activities of organisms.

This paper discusses the epistemic status of biology from the standpoint of the systemic approach to living systems based on the notion of biological autonomy. This approach aims to provide an understanding of the distinctive character of biological systems and this paper analyses its theoretical and epistemological dimensions. The paper argues that, considered from this perspective, biological systems are examples of emergent phenomena, that the biological domain exhibits special features with respect to other domains, and that biology as a discipline (...) employs some core concepts, such as teleology, function, regulation among others, that are irreducible to those employed in physics and chemistry. It addresses the claim made by Jacques Monod that biology as a science is marginal. It argues that biology is general insofar as it constitutes a paradigmatic example of complexity science, both in terms of how it defines the theoretical object of study and of the epistemology and heuristics employed. As such, biology may provide lessons that can be applied more widely to develop an epistemology of complex systems. (shrink)

Endocrinologists apply the idea of feedback loops to explain how hormones regulate certain bodily functions such as glucose metabolism. In particular, feedback loops focus on the maintenance of the plasma concentrations of glucose within a narrow range. Here, we put forward a different, organicist perspective on the endocrine regulation of glycaemia, by relying on the pivotal concept of closure of constraints. From this perspective, biological systems are understood as organized ones, which means that they are constituted of a set of (...) mutually dependent functional structures acting as constraints, whose maintenance depends on their reciprocal interactions. Closure refers specifically to the mutual dependence among functional constraints in an organism. We show that, when compared to feedback loops, organizational closure can generate much richer descriptions of the processes and constraints at play in the metabolism and regulation of glycaemia, by making explicit the different hierarchical orders involved. We expect that the proposed theoretical framework will open the way to the construction of original mathematical models, which would provide a better understanding of endocrine regulation from an organicist perspective.

The Right has a long history of questioning the importance of race analysis. Recently, the conceptual and political status of race has come under increased scrutiny from the Left. Bracketing the language of ‘race’ has meant that the discourse of skin groups remains at the level of abstraction and does not speak to real groups as such. As a descriptor, race essentializes identity as if skin color were a reliable way to perceive one's self and group as well as others, (...) and questions the viability of a social struggle based on race. In other words, race is not real and discourses that insist on its objective status are ensnared in reification. The response—equally from the Left—has been to reassert the centrality and changing dynamics of race in education and society. They argue that we need to develop more, rather than less, complex discourses on race. Orientations that attempt to discredit race analysis are therefore unable to dismantle the racial system because they refuse its significance as an autonomous system of interpellations. In other words, race is real. This essay appraises the debate within the Left about the status of race, their projections about the future of race, and the kind of struggle they promote in order to realize a society freed from the chains of racism.

Perception and action are tightly coupled. However, there is still little recognition of how individual motor constraints impact perception in everyday life. Here we asked whether and how the motor slowing that accompanies aging influences the sense of visual speed. Ninety-four participants aged between 18 and 90 judged the natural speed of video clips reproducing real human or physical motion. They also performed a finger tapping task and a visual search task, which estimated their motor speed and visuospatial attention speed, (...) respectively. Remarkably, aged people judged videos to be too slow, as compared to younger people: the Point of Subjective Equality, which estimated the speed bias in the SoS task, was +4% in young adults, +12% in old adults and +16% in elders. On average, PSE increased with age at a rate of 0.2% per year, with perceptual precision, adjustment rate, and completion time progressively worsening. Crucially, low motor speed, but not low attentional speed, turned out to be the key predictor of video speed underestimation. These findings suggest the existence of a counterintuitive compensatory coupling between action and perception in judging dynamic scenes, an effect that becomes particularly germane during aging.

This article analyses the Fair Trade sector as a “mixed-form market,” i.e., a market in which different types of players (in this case, nonprofit, co-operative and for-profit organizations) coexist and compete. The purposes of this article are (1) to understand the factors that have led Fair Trade to become a mixed-form market and (2) to propose some trails to understand the market dynamics that result from the interactions between the different types of players. We start by defining briefly Fair Trade, (...) its different dimensions (including the “fair” quality of the products) and its organizational landscape, focusing on the distinction between the pioneer “Alternative Trading Organizations” and the second-mover companies. Then, we recall the theoretical emergence factors for each type of organization (nonprofit, co-operative and for-profit) and apply these emergence factors to the context of Fair Trade. This analysis allows us to capture the specificities of each type of operator with regard to Fair Trade and, thus, to have a better understanding of the dynamics in the sector. Such dynamics includes competition, but also conflict and partnership. Our analysis includes elements on ethical imitation, consumers’ behaviors, effects on welfare and the role of the government.

Despite numerous and increasing attempts to define what life is, there is no consensus on necessary and sufficient conditions for life. Accordingly, some scholars have questioned the value of definitions of life and encouraged scientists and philosophers alike to discard the project. As an alternative to this pessimistic conclusion, we argue that critically rethinking the nature and uses of definitions can provide new insights into the epistemic roles of definitions of life for different research practices. This paper examines the possible (...) contributions of definitions of life in scientific domains where such definitions are used most (e.g., Synthetic Biology, Origins of Life, Alife, and Astrobiology). Rather than as classificatory tools for demarcation of natural kinds, we highlight the pragmatic utility of what we call operational definitions that serve as theoretical and epistemic tools in scientific practice. In particular, we examine contexts where definitions integrate criteria for life into theoretical models that involve or enable observable operations. We show how these definitions of life play important roles in influencing research agendas and evaluating results, and we argue that to discard the project of defining life is neither sufficiently motivated, nor possible without dismissing important theoretical and practical research.

El uso de un conocimiento invariante para alcanzar propósitos intervencionistas o de política es comúnmente aceptado por los enfoques manipulabilistas. Sin embargo, dicho uso plantea dos problemáticas filosóficas que serán examinadas en el presente trabajo. El primer problema es ontológico, y refiere a la dificultad de encontrar genuinos factores causales estables en ciencias sociales. En este sentido, se mostrará que los fenómenos sociales no responden a una lógica de factores estables como los mecanismos o las «capacidades», sino que se adecúan (...) más a una lógica de «árboles de posibilidades” o «resultados de final abierto». El otro problema es de índole epistemológico y refiere a que, incluso si se encuentran contribuciones sociales estables, nada garantiza que dicha estabilidad prevalezca en el futuro. Diferentes tesis que avalan esta problemática serán examinadas, tales como la denominada «crítica de Lucas» o la «teoría del cisne negro». (shrink)

In this paper a critique to philosophical approaches that presuppose invariant knowledge for policy purposes is carried out. It is shown that socioeconomic processes do not fit to the logic of stable causal factors, but they are more suited to the logic of "open-ended results". On the basis of this ontological variation it is argued that ex-ante interventions are not appropriate in the socioeconomic realm. On the contrary, they must be understood in a “dynamic” sense. Finally, derivational robustness analysis is (...) proposed as a useful tool for overcoming the problem of “overconstraint”, a typical problem of economic models. (shrink)

The paper considers two main cases of how the creative arts can inform a greater appreciation of human dignity. The first case explores a form of theater, Commedia dell’Arte that has deep roots in Italian culture. The second recounts a set of theater exercises done with very minimal direction or self-direction in executive education and MBA courses at the Darden School, University of Virginia, in the United States. In both cases we highlight how the creative arts can be important for (...) promoting human dignity in organizations, and how they can lead to a more authentic conversation about values, ethics, and meaning.
