The concept of agency is of crucial importance in cognitive science and artificial intelligence, and it is often used as an intuitive and rather uncontroversial term, in contrast to more abstract and theoretically heavy-weighted terms like “intentionality”, “rationality” or “mind”. However, most of the available definitions of agency are either too loose or unspecific to allow for a progressive scientific program. They implicitly and unproblematically assume the features that characterize agents, thus obscuring the full potential and challenge of modeling agency. (...) We identify three conditions that a system must meet in order to be considered as a genuine agent: a) a system must define its own individuality, b) it must be the active source of activity in its environment (interactionalasymmetry) and c) it must regulate this activity in relation to certain norms (normativity). We find that even minimal forms of proto-celular systems can already provide a paradigmatic example of genuine agency. By abstracting away some specific details of minimal models of living agency we define the kind of organization that is capable to meet the required conditions for agency (which is not restricted to living organisms). On this basis, we define agency as an autonomous organization that adaptively regulates its coupling with its environment and contributes to sustaining itself as a consequence. We find that spatiality and temporality are the two fundamental domains in which agency spans at different scales. We conclude by giving an outlook to the road that lies ahead in the pursuit to understand, model and synthesis agents. (shrink)

A recent paper by Jakl, Jung and Pultr succeeded for the first time in establishing a very natural link between bilattice logic and the duality theory of d-frames and bitopological spaces. In this paper we further exploit, extend and investigate this link from an algebraic and a logical point of view. In particular, we introduce classes of algebras that extend bilattices, d-frames and N4-lattices to a setting in which the negation is not necessarily involutive, and we study corresponding logics. We (...) provide product representation theorems for these algebras, as well as completeness, algebraizability results for the corresponding logics. (shrink)

Whether collective agency is a coherent concept depends on the theory of agency that we choose to adopt. We argue that the enactive theory of agency developed by Barandiaran, Di Paolo and Rohde (2009) provides a principled way of grounding agency in biological organisms. However the importance of biological embodiment for the enactive approach might lead one to be skeptical as to whether artificial systems or collectives of individuals could instantiate genuine agency. To explore this issue we contrast the (...) concept of collective agency with multi-agent systems and multi-system agents, and argue that genuinely collective agents instantiate agency at both the collective level and at the level of the component parts. Developing the enactive model, we propose understanding agency – both at the level of the individual and of the collective – as spectra that are constituted by dimensions that vary across time. Finally, we consider whether collectives that are not merely metaphorically ‘agents’ but rather are genuinely agentive also instantiate subjectivity at the collective level. We propose that investigations using the perceptual crossing paradigm suggest that a shared lived perspective can indeed emerge but this should not be conflated with a collective first-person perspective, for which material integration in a living body may be required.

ESP: El concepto de alma en las filosofías de Platón y Aristóteles, por la posición que ocupa en sus argumentos relativos a la esclavitud, fue central para la estructura ideológica sobre la que se sostuvo la institución esclavista durante la Colonia. Será importante remitirnos, en un primer momento, al estudio de Erwin Rohde sobre este concepto, para examinar la materialidad del hálito y plantear una relación entre la mirada y la configuración de imaginarios. Posteriormente, examinaremos el lugar que tiene (...) el alma en los argumentos de Platón y Aristóteles en favor de esclavitud, con énfasis en el papel de la mirada, el dominio sobre el cuerpo y la naturaleza de los cuerpos esclavizables. Finalmente, revisaremos en la obra de Frantz Fanon una crítica a la mirada europea y occidental que diseca el cuerpo negro al otorgarle un alma. -/- ENG: The concept of the soul in the philosophies of Plato and Aristotle, due to the posi-tion it occupies in their arguments concerning slavery, will be central to the ideo-logical structure on which the institution of slavery was sustained during colonial times. It will be important to refer, at first, to Erwin Rohde’s study of this concept, to examine the materiality of the breath and to propose a relationship between the gaze and the configuration of imaginaries. We will then examine the position of the soul in Plato’s and Aristotle’s arguments in favor of slavery, emphasizing the role of the gaze, the dominion over the body, and the nature of enslaved bodies. Finally, we will review in the work of Frantz Fanon a critique of the European and Western gaze that dissects the black body by granting it a soul. (shrink)
