Historicist and political reflection of Freire, gives us a deep look promising in the world. His conviction that oppressor and oppressed can liberate each other and together build a more just and equal, is embodied in education as an emancipatory praxis, which must be built into a dialogic relationship between teacher and learner. Paulo Freire's postulates it has influence of diverse intellectual currents and in this tour, we find a permanent invocation to Antonio Gramsci's contributions. La reflexión historicista y política (...) de Freire, nos entrega una mirada profundamente esperanzadora del mundo. Su convicción que opresor y oprimido se pueden liberar mutuamente y en conjunto construir una sociedad más justa e igualitaria, se materializa en la educación como una praxis emancipadora, la cual debe construirse en una relación dialógica entre educador y educando. Los postulados de Paulo Freire tienen influencia de diversas corrientes intelectuales y en ese recorrido, encontramos una permanente invocación a los aportes de Antonio Gramsci. (shrink)

In this review, we present some ethical imperatives observed in this pandemic from a data ethics perspective. Our exposition connects recurrent ethical problems in the discipline, such as, privacy, surveillance, transparency, accountability, and trust, to broader societal concerns about equality, discrimination, and justice. We acknowledge data ethics role as significant to develop technological, inclusive, and pluralist societies. - - - Resumen: En esta revisión, exponemos algunos de los imperativos éticos observados desde la ética de datos en esta pandemia. Nuestra exposición (...) busca conectar problemas éticos típicos dentro de esta disciplina, a saber, privacidad, vigilancia, transparencia, responsabilidad y confianza, con preocupaciones a nivel social relacionadas con la igualdad, discrimi nación y justicia. Consideramos que la ética de datos tiene un rol significativo para desarrollar sociedades tecnificadas, inclusivas y pluralistas. (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.

O presente artigo faz uma breve apreciação do texto La réalité et son ombre, de E. Levinas, especificamente acerca de sua consideração em torno do valor da arte como possibilidade de transcendência. Se, em obras posteriores, Levinas ainda permanece de certo modo econômico, e às vezes ambíguo, sobre a questão, neste texto sua crítica permanece dura e direta. Aqui se discute a relação entre imagem, exterioridade e o real. A obra de arte fala? Exigiria uma resposta e seria ética? Neste (...) texto de 1948, encontramos uma série de argumentos, no seu diálogo com a arte, que já pre-param, ou anunciam, o que posteriormente virá como a transcedência do Rosto “que vai além da forma que o delimita”. Palavras-chave: Arte, transcendência, exterioridade, imagem, realidade. (shrink)

The interest in what can be considered 'posthumanism' has surged over the past few years. There is no surprise as to why, given the urgency and immanence of a likely sixth mass extinction event, and the catastrophic consequences of global warming. These processes, all of which fundamentally rest on the foundations of human practices and abuses, are forcing us to rethink our place in existence. The foundations of this position have a history firmly rooted in the daily practices and beliefs (...) of Western cultures. The Contemporary Posthuman confronts these assumptions of truth, head-on. The author follows his conceptual journey with practical steps for putting his philosophy into practice, by drawing on philosophy, design, art, and architecture. (shrink)

A IMPORTÂNCIA DA BOA-FÉ NAS RELAÇÕES DE CONSUMO.

Taking into account one of the meanings of the expression binding precedent and stipulating a definition for that meaning, this article aims to contribute to the concept's structural characterization. By this I mean the effort to identify the legal norms on which the existence and functioning of binding precedents depend and to show that these norms constitute a group of Hohfeldian legal relations between the courts whose precedents must be followed, the courts that must follow them, and the individuals whose (...) legal situations are as a result modified by the observance and the breach of those precedents.

La ética del cuidado es la propuesta teórica feminista más conocida en bioética. Mediante una revisión y análisis bibliográfico abordaré la ética del cuidado e interseccionalidad, como marco para discurso bioético aplicado a las estructuras en la atención de salud y para la toma de decisiones. La ética del cuidado y la interseccionalidad otorgan elementos pocas veces considerados en el análisis bioético, como es el contexto, la subjetividad, la experiencia vivida, las relaciones de cuidado y la responsabilidad con sí misma (...) y los otros. Estos elementos deben permear a la bioética en salud y en el actuar del ser humano con su entorno. (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.

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)

In this paper, I will be primarily concerned with moral issues regarding future people and the environment. When it comes to the future, we have deontological and epistemic limitations. The closer to the present, the higher the certainty and the knowledge we have about facts. Thus, when we intend to find moral clarity regarding a future scenario, we deal with an inverse relation between certainty and time. The main problem is that most ways of dealing with moral issues about future (...) scenarios do not address this relation, and rather focus on things that seem to simplify and clarify the uncertainties of the future. In response to this, I propose a different approach, one that operates neutrally and timelessly dealing with the uncertainties of the future while providing moral groundings that can help to clarify the future’s state of moral vagueness.

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)

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.

En este trabajo de desenmascaramiento representamos este evento como una fiesta de carácter nacional que incluyó elementos del repertorio cultural contemporáneo de las personas rapanui. (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.

Theoretical accounts of development exhibit several internal tensions and face multiple challenges. They span from the problem of the identification of the temporal boundaries of development (beginning and end) to the characterization of the distinctive type of change involved compared to other biological processes. They include questions such as the role to ascribe to the environment or what types of biological systems can undergo development and whether they should include colonies or even ecosystems. In this chapter we discuss these conceptual (...) issues, and we argue that adopting an organizational approach may help solve or clarify them. -/- While development is usually identified with the achievement of an adult form with the capability to reproduce and therefore maintain a lineage, adopting the organizational approach may provide a different strategy, which focuses also on the maintenance of the current organization of the organism. By doing so an organizational approach favors a switch in perspective which consists in analyzing how organisms maintain their viability at each moment of development rather than considering them as going through intermediate stages of a process directed toward a specific goal state. This developmental dimension of biological organization has yet to be given a general and detailed analysis within the organizational theoretical perspective, apart from some preliminary attempts. How a biological organization is maintained through a series of radical organizational changes and what these changes are issues that still require clarification. In this chapter we offer the beginnings of such an analysis of developmental transitions, understood as changes in functionality brought forth by regulatory mechanisms in the context of the continued maintenance of organizational viability at every step.
