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.

La primera parte de este artículo expone la interpretación praxeológica del concepto noológico de “acto”. En la segunda, se muestra la crítica que Antonio González Fernández hace de esta. Su objeción consiste en que los actos no pueden ser considerados cosas reales, sino solo el surgir de estas. A partir de dicha observación a la noología, González Fernández no solo da surgimiento a su praxeología (también conocida como hiparqueología), sino que su sistema filosófico comienza a ser cuestionado por no explicar (...) qué son, en el mundo de los hechos, los actos, más allá de la suposición de que ellos están ahí a pesar de ser invisibles. En la tercera y última sección se presentan algunas hipótesis para procurar solucionar ciertas objeciones al concepto praxeológico de “acto”, tales como el anteriormente mencionado y las aparentes circularidades y posibles contradicciones que hay al interior del sistema praxeológico.

RésuméIntroductionLa motivation est. un thème crucial et répandu en médecine. Que. ce soit pour un scénario clinique ou chirurgical, l’acceptation de prendre une pilule ou de se rendre à une consultation est. essentielle au succès du traitement médical. La “décennie du cerveau” a fourni aux praticiens des données neuroscientifiques substantielles sur le comportement humain, a aidé à expliquer pourquoi les gens font ce qu’ils font et a créé le concept de “cerveau motivé”. Les résultats de la psychologie empirique ont stratifié (...) la motivation en étapes de changement, qui sont devenues plus complexes au fil des décennies. Cette recherche vise à améliorer la compréhension de la façon dont les gens prennent des décisions concernant leur santé et comment mieux comprendre les stratégies et les techniques pour les aider à résoudre les problèmes d’ambivalence de manière efficace et ciblée.MéthodesNous établissons un dialogue avec la phénoménologie de la volonté de Ricoeur afin de comprendre le sens de ces découvertes scientifiques. À partir de la phénoménologie husserlienne, Paul Ricoeur a développé sa pensée en s’éloignant de l’idéalisme transcendantal en émancipant les structures intentionnelles de la volonté du domaine de la perception. Résultats: En introduisant les concepts de volontaire et d’involontaire, Ricoeur s’est. écarté du dualisme cartésien, qui fait du corps un corps d’objet, cible de vicissitudes naturelles. Le nouveau dualisme entre volontaire et involontaire est. traité par référence à ce que Ricoeur a appelé le mystère central de l’existence incarnée, qui considère l’homme “double dans l’humanité, simple dans lavitalité”. Cette dualité permet de considérer le cerveau comme l’organe naturel du comportement dans le corps humain et d’utiliser la psychologie empirique comme moyen d’échapper aux subjectivations superficielles des concepts.ConclusionLa simplicité (ou unité) d’existence invite la médecine à repenser certaines de ses hypothèses philosophiques, de telle sorte que les patients puissent être considérés comme des sujets autonomes avec des projets de vie d’auteur. L’anthropologie ricourienne a un impact éthique profond sur la manière dont la médecine devrait utiliser la technologie, ce qui découle de résultats de psychologie empirique. L’utilisation de ces nouvelles connaissances doit également faire l’objet d’une inspection minutieuse, car elle modifie le rôle social de la science médicale. (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)

O estudo consiste na discussão da perspectiva larrosiana do conceito de experiência, a partir do livro Tremores. Partiu da pergunta: O conceito de experiência como acontecimento fundamenta a necessidade de uma nova língua educacional? O método tratou de pesquisa bibliográfica que teve o início na revisão de literatura sobre o tema, análise sistemática do livro Tremores, da mesma forma que problematização em torno do conceito de acontecimento em Martin Heidegger e de experiência em Walter Benjamin. Como resultado, o conceito de (...) experiência se expressa como raridade e deve ser pensado como acontecimento capaz de trazer novos sentidos. Para Larrosa, pensar novos sentidos é pensar novas realidades, tendo como base os sentidos gerados pelos mecanismos de subjetivação que existem em cada indivíduo. Sendo o sentido individual e subjetivo, é responsável por mostrar a cada indivíduo uma forma de experiência. Assim, a aposta diz respeito à necessidade de se repensar as linguagens, das quais emergem o mundo de cada indivíduo, e, além disso, de pensar a pedagogia como transformadora do que já existe por meio da linguagem. A linguagem possibilita a compreensão de si e do outro, em uma realidade abstrata que se perdeu das palavras e se distanciou da verdadeira experiência e do mundo real, enquanto acontecimento. Por derradeiro, o estudo demonstrou a necessidade de uma nova língua para a educação em Jorge Larrosa, como necessidade de fortalecimento da potência que habita entre aqueles que escutam e aqueles que falam, dos que não desejam colocar fim à identidade do sujeito, destruí-la, mas dar possibilidades para que a identidade se abra a novas significações, a fim de construir o acontecimento, a abertura e o conhecimento.

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.

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.

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 paper we address the question of minimal cognition by investigating the origin of some crucial cognitive properties from the very basic organisation of biological systems. More specifically, we propose a theoretical model of how a system can distinguish between specific features of its interaction with the environment, which is a fundamental requirement for the emergence of minimal forms of cognition. We argue that the appearance of this capacity is grounded in the molecular domain, and originates from basic mechanisms (...) of biological regulation. In doing so, our aim is to provide a theoretical account that can also work as a possible conceptual bridge between Synthetic Biology and Artificial Intelligence. In fact, we argue, Synthetic Biology can contribute to the study of minimal cognition, by providing a privileged approach to the study of these mechanisms by means of artificial systems. (shrink)

In this article an epistemological framework is proposed in order to integrate the emergentist thought with systemic studies on biological autonomy, which are focused on the role of organization. Particular attention will be paid to the role of the observer’s activity, especially: (a) the different operations he performs in order to identify the pertinent elements at each descriptive level, and (b) the relationships between the different models he builds from them. According to the approach sustained here, organization will be considered (...) as the result of a specific operation of identification of the relational properties of the functional components of a system, which do not necessarily coincide with the intrinsic properties of its structural constituents. Also, an epistemological notion of emergence—that of “complex emergence”—will be introduced, which can be defined as the insufficiency, even in principle, of a single descriptive modality to provide a complete description of certain classes of systems. This integrative framework will allow us to deal with two issues in biological and emergentist studies: (1) distinguishing the autonomy proper of living systems from some physical processes like those of structural stability and pattern generation, and (2) reconsidering the notion of downward causation not as a direct or indirect influence of the whole on its parts, but instead as an epistemological problem of interaction between descriptive domains in which the concept of organization proposed and the observational operations related to it play a crucial role.
