Building on the original formulation of the autopoietic theory (AT), extended enactivism argues that living beings are autopoietic systems that extend beyond the spatial boundaries of the organism. In this article, we argue that extended enactivism, despite having some basis in AT’s original formulation, mistakes AT’s definition of living beings as autopoietic entities. We offer, as a reply to this interpretation, a more embodied reformulation of autopoiesis, which we think is necessary to counterbalance the (excessively) disembodied spirit of AT’s original (...) formulation. The article aims to clarify and correct what we take to be a misinterpretation of AT as a research program. AT, contrary to what some enactivists seem to believe, did not (and does not) intend to motivate an extended conception of living beings. AT’s primary purpose, we argue, was (and is) to provide a universal individuation criterion for living beings, these understood as discrete bodies that are embedded in, but not constituted by, the environment that surrounds them. However, by giving a more explicitly embodied definition of living beings, AT can rectify and accommodate, so we argue, the enactive extended interpretation of autopoiesis, showing that although living beings do not extend beyond their boundaries as autopoietic unities, they do form part, in normal conditions, of broader autopoietic systems that include the environment.

Standard economic theory usually analyzes the decisions made by individuals as a rational process in which each individual has sound and consistent preferences and makes decisions according to the principle of subjective expected utility maximization. Starting from the pioneering work of Herbert Simon and the research of cognitive psychologists Kahneman and Tversky, the contributions provided by cognitive-behavioral theory have repeatedly shown that real agents make choices in a way that differs systematically from standard theory, hence highlighting its limits. Rather than (...) considering standard normative theory as false or unable to explain the data obtained by behavioral economists, several economists decided to develop new formal models that could include the results of different experiments and empirical observations that captured all dimensions of the choice made by an individual. In this sense, they proposed new models that were not intended to challenge standard theory but rather designed to provide a kind of psychological expansion to it. This article has the aim of describing and analyzing the advantages and limitations of these new models, which unfortunately are not always suited to describe the individual behavior, the individuals’ actions, or the equilibria due to the combination of the actions of several players. To overcome the limits of these models, we decided to take into consideration the unfortunately unfinished work of Michael Bacharach, who strived to understand the individual and collective forms of rationality without applying only analytical devices or a theoretical vision of the world but bringing rationality back to the perception level of the agents.

For a, b > 0, we consider a temporally homogeneous, one-dimensional diffusion process X(t) defined over I = (-b, a), with infinitesimal parameters depending on the sign of X(t). We suppose that, when X(t) reaches the position 0, it is reflected rightward to δ with probability p > 0 and leftward to -δ with probability 1 - p, where δ > 0. Closed analytical expressions are found for the mean exit time from the interval (-b, a), and for the probability (...) of exit through the right end a, in the limit δ → 0+, generalizing the results of Lefebvre, holding for asymmetric Wiener process. Moreover, in alternative to the heavy analytical calculations, a numerical method is presented to estimate approximately the quantities above. Furthermore, on the analogy of skew Brownian motion, the notion of skew diffusion process is introduced. Some examples and numerical results are also reported. (shrink)

Standard equilibrium economic models focus on interdependencies. This text develops a theory which is based on disequilibria. The model proposed is a heuristic tool that makes it possible to explore these disequilibria in relation to Western economies.

Questions about how closure is achieved in disputes involving new observational or experimental claims have highlighted the role of bodily knowledge possibly irreducible to written experimental protocols and instructions how to build and operate instruments. This essay asks similar questions about a scenario that is both related and significantly different: the replication of an invention, not of an observation or the instrument through which it produced. Furthermore, the machine considered here—Galileo’s compass or sector—was not a typical industrial invention (like a (...) spinning jenny), but a mathematical invention (a calculator), that is, a machine that produces numbers, not yarn. This case study describes some of the similarities and differences between replicating experiments, traditional machines producing material outputs, and mathematical inventions yielding calculations or information. This comparison indicates that, as in other kinds of replication, the replication of mathematical inventions involves texts (the calculator’s instructions) but that in this case bodily knowledge cannot be properly described as either tacit or explicit. It rather takes the shape of memory—muscle memory—that may be recalled from reading the instructions. (shrink)

The cognitive impairments shown by brain-damaged patients emphasize the role of task difficulty as a major determinant for performance. We discuss the proposal of Kurzban et al. in light of our findings on right-hemisphere–damaged patients, who show increasing awareness deficits for the contralesional hemispace when engaged with resource-consuming dual tasks. This phenomenon is readily explained by the assumption of unspecific depletable resources.

Few thinkers have left such an influence across such a diverse range of studies as Michel Foucault has. This book pays homage to that diversity by presenting a multidisciplinary series of analyses dedicated to the question of power today.

Les études récentes consacrées à la pensée épistémologique de Bachelard en France et en Italie mettent en évidence le caractère créatif et propulsif assigné aux mathématiques dans la construction du réel physique. Les travaux de Bachelard consacrés à la mécanique quantique dans les années '30, et en particulier à la physique théorique de Dirac, introduisent un concept particulier, celui de« rêverie anagogique » pour comprendre le caractère toujours plus abstrait et créateur de la mathématique dans la pensée des différents niveaux (...) de la réalité physique. Sur les traces de ce que Federigo Enriques qualifiait de « poésie mathématique », Bachelard propose une véritable « nouménologie mathématique » qui fournit les bases épistémiques pour comprendre I '« efficacité rationnelle » des mathématiques et leur application au réel. Pour toutes ces raisons, Bachelard utilisera dans ces années-là un terme nouveau pour désigner son engagement rationaliste: le « surrationalisme » qui condense ce qu' Enriques appelait « la philosophie implicite » dans les sciences, soit la « pensée des sciences » où, à travers la fonction jouée par la « rêverie anagogique », les mathématiques mettent en acte les « enjeux » continus du rationnel comme tel.

Analyzing the Dialogue between a Philosopher and a Student of the Common Laws of England by Thomas Hobbes, the essay traces the historical tradition and the reasons for its secular underestimation. The Hobbesian text is placed within the history of English law and the controversies that accompanied and followed the revolution of 1640. It is then compared with the political works of Hobbes, showing how the silence of the law is gradually replacing the state of nature as image of the (...) death of the Commonwealth . The Dialogue proves to be a firm position in favor of an universal and equal capacity to understand what the law is. This latter is the product of the will of a sovereign, who however is the institutionalization of the authorization of the individuals who constitute it. (shrink)

Resumo: Nesta exposiçáo proponho efetuar uma apresentaçáo dos problemas interpretativos fundamentais e das diferentes leituras que se tem realizado em relaçáo à filosofia das formas simbólicas cassireriana. Palabvas chaves: Cassirer. Filosofia das formas simbólicas. Formas simbólicas.

This provocative volume, one of the most important interpretive works on the philosophical thought of the Renaissance, has long been regarded as a classic in its field. Ernst Cassirer here examines the changes brewing in the early stages of the Renaissance, tracing the interdependence of philosophy, language, art, and science; the newfound recognition of individual consciousness; and the great thinkers of the period—from da Vinci and Galileo to Pico della Mirandola and Giordano Bruno. _The Individual and the Cosmos in Renaissance (...) Philosophy_ discusses the importance of fifteenth-century philosopher Nicholas Cusanus, the concepts of freedom and necessity, and the subject-object problem in Renaissance thought. “This fluent translation of a scholarly and penetrating original leaves little impression of an attempt to show that a ‘spirit of the age’ or ‘spiritual essence of the time’ unifies and expresses itself in all aspects of society or culture.”—_Philosophy_.

Una de las características de la transmisión manuscrita de los _Tractatus _ _de Pedro Hispano es el hecho de que el tratado sobre las _Categorías _no siempre ocupa el mismo lugar al interior de la obra. En algunos manuscritos se encuentra en tercer lugar, después del tratado acerca de la _Isagoge _de Porfirio, siguiendo el orden tradicional de la _logica vetus. _Pero en algunos otros, se encuentra en quinto lugar, después del tratado sobre los _Tópicos _y antes del tratado sobre (...) la suposición. En los dos casos, el lugar de las _Categorías _de Aristóteles en la lógica es definido por la noción de “término”. El propósito de este artículo es entender por qué ocurre esta variación, ya que no es teóricamente neutral. Por tanto, para atender al problema del orden de aparición del tratado sobre las _Categorías _dentro de la lógica, se presentarán tres de los más destacados comentaristas de los _Tractatus_: Juan Buridan, Juan Versor y Pedro Tartaret. Este ejercicio proporcionará algunas conclusiones sobre la relación entre las categorías y la teoría de la suposición, y también sobre la _vexata quaestio _acerca del sujeto de las categorías.

A análise dos cânones conciliares e das epístolas pontifícias mostra que os cristãos estiveram diretamente envolvidos com eventos espetaculares e, não obstante as reiteradas proibições por parte da hierarquia, a dança e a música permaneceram centrais seja na vida pública seja na privada, ingressando inclusive nos ritos e nos edifícios cristãos.
