Whereas most branches of neuroscience are thought to provide mechanistic explanations, systems neuroscience is not. Two reasons are traditionally cited in support of this conclusion. First, systems neuroscientists rarely, if ever, rely on the dual strategies of decomposition and localization. Second, they typically emphasize organizational properties over the properties of individual components. In this paper, I argue that neither reason is conclusive: researchers might rely on alternative strategies for mechanism discovery, and focusing on organization is often appropriate and consistent with (...) the norms of mechanistic explanation. Thus, many explanations in systems neuroscience can also be viewed as mechanistic explanations. (shrink)

We show that basic hybridization (adding nominals and @ operators) makes it possible to give straightforward Henkin-style completeness proofs even when the modal logic being hybridized is higher-order. The key ideas are to add nominals as expressions of type t, and to extend to arbitrary types the way we interpret $@_i$ in propositional and first-order hybrid logic. This means: interpret $@_i\alpha _a$ , where $\alpha _a$ is an expression of any type $a$ , as an expression of type $a$ that (...) rigidly returns the value that $\alpha_a$ receives at the i-world. The axiomatization and completeness proofs are generalizations of those found in propositional and first-order hybrid logic, and (as is usual inhybrid logic) we automatically obtain a wide range of completeness results for stronger logics and languages. Our approach is deliberately low-tech. We don’t, for example, make use of Montague’s intensional type s, or Fitting-style intensional models; we build, as simply as we can, hybrid logicover Henkin’s logic. (shrink)

Reductionism has dominated science and philosophy for centuries. Complexity has recently shown that interactions—which reductionism neglects—are relevant for understanding phenomena. When interactions are considered, reductionism becomes limited in several aspects. In this paper, I argue that interactions imply nonreductionism, non-materialism, non-predictability, non-Platonism, and non-Nihilism. As alternatives to each of these, holism, informism, adaptation, contextuality, and meaningfulness are put forward, respectively. A worldview that includes interactions not only describes better our world, but can help to solve many open scientific, philosophical, and (...) social problems caused by implications of reductionism.

Investigates the resolution of contradictions and ambiguous derogations in a code, by means of the imposition of partial orderings.

The philosophical conception of mechanistic explanation is grounded on a limited number of canonical examples. These examples provide an overly narrow view of contemporary scientific practice, because they do not reflect the extent to which the heuristic strategies and descriptive practices that contribute to mechanistic explanation have evolved beyond the well-known methods of decomposition, localization, and pictorial representation. Recent examples from evolutionary robotics and network approaches to biology and neuroscience demonstrate the increasingly important role played by computer simulations and mathematical (...) representations in the epistemic practices of mechanism discovery and mechanism description. These examples also indicate that the scope of mechanistic explanation must be re-examined: With new and increasingly powerful methods of discovery and description comes the possibility of describing mechanisms far more complex than traditionally assumed.

In game-theoretic signaling models, evolution tends to favor perfectly precise signaling systems, but in the natural world communication is almost always imprecise. I argue that standard explanations for this discrepancy are only partially sufficient, and I show that communication is often ambiguous because signal senders take advantage of context sensitivity. As evidence, I make two additions to the signaling model: a cost for more complex signaling strategies and the ability to combine information in signals with independent information. Analysis and simulation (...) of the altered model shows that it leads to the predicted outcome of evolution favoring ambiguous signaling. (shrink)

Freire is one of the most powerful voices challenging the hegemony of bureaucratic and banking educational systems. His voice was particularly influential impacting revolutionary processes and progressive social movements while at the same time learning from their practices. However, some silences in his oeuvres requires further examination. In this article, we focus on the silences of Freire regarding education and its relationship with work and labor, gender issues, and citizenship building.

Os projetos de psicologia científica enfrentam pelo menos duas ameaças. A primeira delas surge quando uma proposta de psicologia tenta seguir os cânones da ciência moderna. Nesse caso, torna-se necessário "objetivar o fenômeno psicológico", o que, geralmente, é feito por meio da sua tradução em termos fisiológicos. Mas, nesse ponto, a especificidade da psicologia é ameaçada pelo reducionismo fisiológico. A segunda ameaça aparece quando um projeto de psicologia tenta evitar o reducionismo fisiológico defendendo a natureza subjetiva irredutível do fenômeno psicológico. (...) No entanto, isso coloca uma série de dificuldades metodológicas. Dessa maneira, a segunda ameaça às propostas de psicologia científica é o mentalismo, que impõe limitações ao emprego do método científico. O presente ensaio tem o objetivo de mostrar como o projeto de psicologia científica de Tolman pode ser visto como uma alternativa a essas duas ameaças. Em primeiro lugar, examinamos em que medida a concepção de comportamento como fenômeno molar afasta Tolman do reducionismo fisiológico. Em seguida, analisamos algumas dificuldades decorrentes dessa proposta, em especial, as limitações inerentes à epistemologia realista - adotada inicialmente por Tolman. Por fim, apresentamos a proposta tolmaniana de superação dessas dificuldades: trata-se da analogia entre teorias científicas e mapas, que revela a adoção de uma epistemologia instrumentalista por Tolman.

O presente artigo aborda as concessões feitas por Husserl no texto de Prolegômenos, na segunda edição de Investigações Lógicas. O artigo mostra que a concessão mais difícil estaria exatamente na manutenção da ideia de “verdade em si”. Por um lado, Husserl afirma que a “verdade em si” não poderia depender da constituição da natureza humana, pois tal dependência abalaria o próprio sentido da ideia de “verdade”. Por outro lado, não deixaria de reconhecer a insuficiência da ideia de “verdade em si”, (...) na medida em que tal ideia encobriria o importante problema da relação entre o real e o ideal. (shrink)

En este artículo discuto cómo es que la idea intuitiva de que las cosas podrían cambiar, combinada con principios excesivamente plausibles, nos lleva a la paradoja de Chisholm. Arguyo que la mejor respuesta a esta paradoja –pues efectúa la menor mutilación a nuestros principios teóricos y asunciones intuitivas– es la postura esencialista. Primero expongo algunas motivaciones para hacer una teoría metafísica que explique la modalidad de re. Luego reviso los principios a los que estaremos regresando en el curso del artículo. (...) Entonces muestro cómo ellos, conjuntamente, implican la paradoja de Chisholm. Después reviso las posibles fuentes de esta paradoja, rechazando varias salidas posibles. Argumento que la fuente de la paradoja está en que nuestros principios teóricos son demasiado liberales, y que la opción esencialista subsana este defecto. (shrink)

The present paper approaches the idea of a "transcendence in immanence" in the phenomenology of Husserl. Shows us that the exercise of phenomenological method in relation to the position of existence of facts imposes a variation of the "transcendent" in Husserl. Initially conceived as a source of doubt and uncertainty, the transcendent is revealed in a second moment in the immanence of transcendental subjectivity: the thing in its originary giving. The paper focuses thus in the polarity between the pure self (...) and the object intentional. Shows us that the object oscilates between the immanent character of the noema and the that transcends the noema. Finally, reveals us that the pure self is a peculiar transcendence in immanence, a transcendence ambivalent that at same time constitute the object and itself constitutes. (shrink)

This book investigates Hermann Weyl’s work on the problem of space from the early 1920s onwards. It presents new material and opens the philosophical problem of space anew, crossing the disciplines of mathematics, history of science and philosophy. With a Kantian starting point Weyl asks: among all the infinitely many conceivable metrical spaces, which one applies to the physical world? In agreement with general relativity, Weyl acknowledges that the metric can quantitatively vary with the physical situation. Despite this freedom, Weyl (...) “deduces”, with group-theoretical technicalities, that there is only one “kind” of legitimate metric. This construction was then decisive for the development of gauge theories. Nevertheless, the question of the foundations of the metric of physical theories is only a piece of a wider epistemological problem. Contributing authors mark out the double trajectory that goes through Weyl’s texts, from natural science to philosophy and conversely, always through the mediation of mathematics. Readers may trace the philosophical tradition to which Weyl refers and by which he is inspired, and explore the mathematical tradition that permitted Weyl to elaborate and solve his mathematical problem of space. Furthermore, this volume analyzes the role of the interlocutors with whom Weyl discussed the nature of physical space. This volume features the work of top specialists and will appeal to postgraduates and scholars in philosophy, the history of science, mathematics, or physics. (shrink)

This book traces the origins and evolution of cybersemiotics, beginning with the integration of semiotics into the theoretical framework of cybernetics and information theory. The book opens with chapters that situate the roots of cybersemiotics in Peircean semiotics, describe the advent of the Information Age and cybernetics, and lay out the proposition that notions of system, communication, self-reference, information, meaning, form, autopoiesis, and self-control are of equal topical interest to semiotics and systems theory. Subsequent chapters introduce a cybersemiotic viewpoint on (...) the capacity of arts and other practices for knowing. This suggests pathways for developing Practice as Research and practice-led research, and prompts the reader to view this new configuration in cybersemiotic terms. Other contributors discuss cultural and perceptual shifts that lead to interaction with hybrid environments such as Alexa. The relationship of storytelling and cybersemiotics is covered at chapter length, and another chapter describes an individual-collectivity dialectics, in which the latter constrains the former, but the former fuels the latter. The concluding chapter begins with the observation that digital technologies have infiltrated every corner of the metropolis - homes, workplaces, and places of leisure - to the extent that cities and bodies have transformed into interconnected interfaces. The book challenges the reader to participate in a broader discussion of the potential, limitations, alternatives, and criticisms of cybersemiotics. (shrink)

Trata-se de uma investigação sobre a teoria dos primeiros princípios da razão prática na obra de Tomás de Aquino. No centro dessa teoria está o termo “sindérese”, cujo conteúdo foi elaborado nas discussões da filosofia e da teologia medievais, a partir de sua menção na Glosa de Jerônimo a Ezequiel. Tal termo designa um conceito que apresenta um caráter inovador dentro da teoria da ação moral em comparação com a ética aristotélica. Afinal, Tomás de Aquino o entende como o hábito (...) dos primeiros princípios da moral, equivalente ao hábito dos primeiros princípios teóricos de Aristóteles. Dessa forma, o interesse é compreender como o conceito de sindérese é recebido e desenvolvido na filosofia moral de Tomás de Aquino através da análise das três questões tradicionais: de sua natureza, de sua infalibilidade e de sua extinção.

We consider the problem of measurement using the Lindblad equation, which allows the introduction of time in the interaction between the measured system and the measurement apparatus. We use analytic results, valid for weak system-environment coupling, obtained for a two-level system in contact with a measurer (Markovian interaction) and a thermal bath (non-Markovian interaction), where the measured observable may or may not commute with the system-environment interaction. Analysing the behavior of the coherence, which tends to a value asymptotically close to (...) zero, we obtain an expression for the time of measurement which depends only on the system-measurer coupling, and which does not depend on whether the observable commutes with the system-bath interaction. The behavior of the coherences in the case of strong system-environment coupling, found numerically, indicates that an increase in this coupling decreases the measurement time, thus allowing our expression to be considered the upper limit for the duration of the process.

The aim of this note is to undermine structural realism by testing the soundness of its main claim. If scientific theories represent the structure of the world, structural realism needs a general account of representation. Representation is the crux of structural realism, because structure/ontology distinction collapses. Mathematical structures are ontologyladen. DOI:10.5007/1808-1711.2010v14n2p201.

Este escrito reconstruye las razones y figuras tanto filosóficas como teológicas que originaron el “giro teológico” de la fenomenología. Un punto importante lo constituye la influencia de Dionisio Areopagita en el pensamiento de Heidegger, no siempre reconocida como sí ocurre, en cambio, con la presencia de Eckhart. Esta génesis implica la recepción cristiana del neoplatonismo, que compone la llamada “teología negativa”. Bajo esta clave de lectura, el “giro teológico” apunta a ampliar los límites de la razón para superar la razón (...) científica y dar cabida a una razón que incluya la donación de lo invisible.

La experiencia y el testimonio son la clave central de la revelación cristiana. Sin embargo, se puede apreciar que en diferentes estudios contemporáneos sobre el tema se insiste más en el testimonio que en la experiencia misma que da origen al testimonio. Urge la reflexión sobre la posibilidad y la efectividad de la experiencia y del testimonio, y más en un mundo en el que la idea de Dios o absoluto ya no tiene raíces en la metafísica representacional y no (...) cabe en los estrechos límites de un concepto. Las críticas realizadas al cristianismo en la época de la Modernidad han servido para purificar el mismo cristianismo, pues las representaciones idolátricas de Dios que se habían incrustado en él van siendo corregidas en la reflexión contemporánea: en la teología y en la filosofía.

Epistemic foundationalism is confronted with a serious objection in relation to the basic beliefs placed as the foundation of justification and knowledge: the well-known Sellars’s problem. We try to characterize the problem advanced by Sellars and show some plausible answers which depend on the understanding of sensory experience and the very nature of perception, which allows us to avoid the objection and defend a moderate version of foundationalism.

Lane et al. propose an integrative model for the reconsolidation of traces in their timely and impressive article. This commentary draws attention to tradeoffs between accuracy and self-narrative integrity in the model. The tradeoffs concern the sense of agency in memory and its role in both implicit and explicit memory reconsolidation, rather than balances concerning degrees of emotional arousal.

In his 2000 paper, Hookway intends to argue that Fumerton’s Principle of Inferential Justification does not have the sceptical consequences that Fumerton sees into it. We think Hookway is right in holding this. However, after commenting on his main considerations for this thesis, we shall develop an independent line of argument which reinforces the same conclusion.

We report three experimental studies of reasoning with double conditionals, i.e. problems based on premises of the form: If A then B. If B then C. where A, B, and C, describe everyday events. We manipulated both the logical structure of the problems, using all four possible arrangements (or “figures” of their constituents, A, B, and C, and the believability of the two salient conditional conclusions that might follow from them, i.e. If A then C, or If C then A. (...) The experiments showed that with figures for which there was a valid conclusion, the participants more often, and more rapidly, drew the valid conclusion when it was believable than when it was unbelievable. With figures for which there were no valid conclusions, the participants tended to draw whichever of the two conclusions was believable. These results were predicted by the theory that reasoning depends on constructing mental models of the premises. (shrink)

We study the general problem of strengthening the logic of a given matrix with a set of axioms, using the idea of rexpansion. We obtain two characterization methods: a very general but not very effective one, and then an effective method which only applies under certain restrictions on the given semantics and the shape of the axioms. We show that this second method covers a myriad of examples in the literature. Finally, we illustrate how to obtain analytic multiple-conclusion calculi for (...) the resulting logics. (shrink)

A central claim in Luiz Pessoa’s (2013) book is that the terms “emotion” and “cognition” can be useful in characterizing behaviors but will not be cleanly mapped into brain regions. In order to be verified, this claim requires models for the integration and interfacing of emotion and cognition; yet, such models remain problematic.

En este trabajo, el autor analiza las contradicciones que el multiculturalismo plantea en las sociedades actuales, resaltando la importante mediación que el sistema político democrático lleva a cabo en la resolución de las mismas. A partir de los artículos de tres autores ('The Politics ofRecognition" de CH Taylor: "Struggles for Recognition in Constitutional States" de J. Habermas y "Legitimacy and Diversity: Dialectical Reflections on Analytical Distinctions" de T. McCarthy) y de la referencia final al trabajo de Rawls 'The Law of (...) the People", expone una serie de momentos teóricos que representan diferentes estadios en la discusión entre el pensamiento liberal y el comunitarismo, y que componen un proceso explicativo en el que cada uno de esos momentos supondría una superación teórica del anterior. En concreto, el autor trata de situar la discusión sobre el reconocimiento del derecho a la diferencia, en el terreno en el que del análista del modelo teórico del liberalismo más acorde con el reconocimiento de derechos a las colectividades-el republicanismo comunitarista al que se refiere Taylor-, se pase al análisis del tipo de sistema político dentro del cual se reconozca la diferencia y la existencia de otras culturas como algo que ya estaba implícito en la teoría de los derechos. Este sistema político sería la democracia deliberativa y su procedimiento discursivo para tomar decisiciones y llegar a acuerdos, propuesto por J. Habermas. El trabajo de McCarthy tratarla de resolver algunas fisuras en la democracia deliberativa que afectarían a su legitimidad por cuanto suponen un menoscabo a la idea misma de las diferencias. Finalmente, la alusión a Rawls permite al autor erigir el sistema de los derechos humanos en el estándar mínimo necesario para llegar a un acuerdo global lo suficientemente amplio y abstracto como para garantizar el máximo respeto a las diferencias. Un acuerdo que, insiste el autor, sólo puede enmarcarse en un proyecto democrático con dimensión internacional, al que llama "horizonte cosmopolitamente democrático". (shrink)

The volumes of the 'Symposium Aristotelicum' have become the obligatory reference works for all studies on Aristotle. In this eighteenth volume a distinguished group of scholars offers a chapter-by-chapter study of the first book of Aristotle's Metaphysics. Book Alpha is not just a fundamental text for reconstructing the early history of Greek philosophy; it sets the agenda for Aristotle's own project of wisdom after what he had learned from his predecessors. The volume comprises eleven chapters, each dealing with a different (...) section of the text, a new edition of the Greek text, based on an exhaustive examination of the complex manuscript and indirect tradition, and an introduction which offers new insights into the relation between the two divergent traditions of the text.

In the first place, I discuss the main papers and books on Durkheim published in recent years, where no attention is given to the phenomenological interpretations of his work. Then I expose different phenomenological readings of Durkheim, some of them positive, some negative, some ambivalent. Later I find that there is in Durkheim an implicit practice of phenomenology, inspired by Descartes’ Meditations on first philosophy. Consequently, I support Tyriakian’s thesis that there is in Durkheim an implicit phenomenological approach, despite his (...) positivism. Then I wonder whether this tacit approach produces a phenomenological ontology of the social world. I find that it actually does, especially in what regards to social facts considered as things. I argue that Durkheim’s conception of social things is consistent with Husserl’s notion of ideal objectivities. I conclude that Durkheim’s rule of considering social facts as things is part of his phenomenological legacy and that it does not contradict the idea that they also are “states lived”. (shrink)

En particular, modificaciones que permitan reconocer la duración genuina de las emociones. También sugiero protocolos de reconocimiento para la dirección y la manifestación (...) de emociones.
