Oser parler du " don ", c'est prendre à rebours la logique économique et les dérives sociales qu'elle génère ; c'est faire droit à une attente inamissible des personnes et des sociétés. " Faire un don " perturbe de l'intérieur les mouvements économiques et leurs lois d'échange. Marcel Mauss a estimé que l'échange de dons unifiait les sociétés, mais un don sans retour, et donc sans contre-don, peut ouvrir celles-ci à des dimensions d'essentielle humanité, irréductibles aux lois des marchés. Jacques (...) Derrida et Jean-Luc Marion accompagnent la réflexion que voici. Paul Gilbert et Silvano Petrosino y rappellent que nos vies n'appartiennent pas au seul domaine de l'échange égalitaire et que la gratuité y est essentielle. L'amitié et la paternité en témoignent.

Post-Gibson attempts to set out a definition of affordance generally agree that this notion can be understood as a property of the environment with salience for an organism’s behavior. According to this view, some scholars advocate the idea that affordances are dispositional properties of physical objects that, given suitable circumstances, necessarily actualize related actions. This paper aims at assessing this statement in light of a theory of affordance perception. After years of discontinuity between strands of empirical and theoretical research, the (...) time is ripe for addressing the question of whether the dispositional interpretation of affordance is in accordance with some recent evidence from cognitive science and neuroscience. Following this line, I clarify that there are some cases of affordance-related effects that neither require the actualization of an action, nor the presence of an action-related property bearer in the environment, and that the identification of affordance with physical properties provides only a partial explanation of the wide range of affordance-related effects. Accordingly, I argue in favor of a more general account of affordance perception based on the ability to directly detect perceptual patterns in the environment. (shrink)

Devices of direct democracy are an important structural element in Switzerland's political system. In this article, institutions and functions of Switzerland's direct democracy will be presented. Then the author will pursue whether the direct democracy can be used as a device to prevent a dysfunctional parliamentary system of government. He comes to the conclusion that Switzerland's direct democracy is not an exportable good. We know from the Swiss experience that there is no single model that describes how initiatives and referendums (...) function in every state. (shrink)

Radical Enactivism holds that the best explanation of basic forms of cognition is provided without involving information of any sort. According to this view, the ability to perceive visual affordances should be accounted for in terms of extensional covariations between variables spanning the agent’s body and the environment. Contrary to Radical Enactivism, I argue that the intensional properties of cognition cannot be ignored, and that the way in which an agent represents the world has consequences on the explanation of basic (...) sensorimotor abilities. To support this claim, I show that the perception of visual affordances is not segregated from higher forms of cognition; rather, it is modulated by the agent’s ability to recognize the semantic identity of the visual target. Accordingly, since the semantic recognition of an object involves a way of representing it under a certain description, it can be inferred that the perception of visual affordances cannot be accounted for without considering the intensional properties of cognition. This poses an explanatory issue for Radical Enactivism. (shrink)

Antropologia do espaço, de Filomena Silvano, é umlivro comvocaçãomarcadamente didáctica, mas que constitui uma notável síntese (deveríamos dizer ummapa?) de uma disciplina (a antropologia) que tem vindo a ganhar (pelos motivos que Jameson enunciava) uma.

Russell's introduction of negative facts to account for the truth of "negative" sentences or beliefs rests on his collaboration with Wittgenstein in such efforts as the characterization of formal necessity, the theory of logical atomism, and the use of the Ideal Language. In examining their views we arrive at two conclusions. First, that the issue of negative facts is distinct from questions of meaning or intentionality; what a sentence or belief means or is about rather than what makes it true (...) or false. Second, that the ontological use of the Ideal Language is incompatible with the requirements of its employment in the logical study of inferences. On this basis we conclude that despite elaborations by recent proponents, the doctrine of negative facts lacks adequate support, and perhaps more importantly, it is proper ontological method to free the Ideal Language from the exigencies of a symbolism constructed for logical investigation.
