“Are living beings extended autopoietic systems? An embodied reply,” makes the case for grounding the autopoietic definition of living beings to the discrete bodies of organisms rather than to autopoietic systems that extend beyond the organisms into their environments. They attempt this grounding by amending a clause to the original formulation of autopoiesis that identifies living beings with their bodies, and then they explicitly define “bodies”. This commentary makes the case that bodily grounding can be derived from molecular autopoiesis by taking the molecular domain seriously, and no new amendment is required.

Key words: autopoiesis, embodiment, organisms.

Living systems are characterized as self-generating and self-maintaining systems. This type of characterization allows integration of a wide variety of detailed knowledge in biology. The paper clarifies general notions such as processes, systems, and interactions. Basic properties of self-generating systems, i.e. systems which produce their own parts and hence themselves, are discussed and exemplified. This makes possible a clear distinction between living beings and ordinary machines. Stronger conditions are summarized under the concept of self-maintenance as an almost unique character of living systems. Finally, we discuss the far-reaching consequences that the principles of self-generation and self-maintenance have for the organization, structure, function, and evolution of singleand multi-cellular organisms.

Upshot: The authors offer a theory of agency that is general enough to apply to whole organisms and single cells, and meaningful enough to highlight problems that embodied cognition theory has overlooked. The authors insist that the interesting thing about minds is what goes on in between activities; this leaves unclear what a specifically enactivist empirical program could look like. But the book can be read as a contribution to a broader project of instituting a full-blown post-cognitivist science of the mind.

The classical formulation of the object of ethics refers to a knowledge of the rules of the adaptation of the human species to their natural environments, to normative expectations supposed in the others and to the biographical evolution of the self. Accordingly, a doctrine of the duties was edified on three pillars, embracing a reference to the duties towards nature, towards the others and towards oneself. Notwithstanding the fact that human action obeys to a variety of factors including bio-physiological conditions and the dimensions of the social environment, ancient and modern metaphysical models of ethics favored the commendatory discourse about the predicates “right” and “wrong,” concurring to ultimate goals. The ethical discussions consisted chiefly in the investigation of the adequacy of the subordinate goals to the final ends of the human action or in the treatment of the metaphysical questions related to free will or determinism, the opposition of the intentionality of the voluntary conduct of man to the mechanical or quasi-mechanical responses of the inferior organisms or machines. From a “second order” approach to the ethical action and imperatives, I propose with this book a critical analysis of the metaphysical and the Kantian ethics. Relevance: In “Ethics and Second-Order Cybernetics” (1992) Heinz von Foerster referred the importance of the application of his notion of “second-order cybernetics” to ethics and moral reasoning. Initially, second-order cybernetics intended an epistemological discussion of recursive operations in non-trivial machines, which were able to include in their evolving states their own self-awareness in observations. The application of his views to ethics entails new challenges. After H. von Foerster essay, what I mean with “second-order ethics is an attempt to identify the advantages of the adoption of his proposal, some consequences in the therapeutically field and lines for new developments.

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 (interactional asymmetry) and c) it must regulate this activity in relation to certain norms (normativity). We find that even minimal forms of proto-cellular 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 synthesize agents.

Excerpt: Inthe French language, the verb vivre means both “to be alive” (Leben) and “to have an experience, to feel something” (Erleben): it is neutral with respect to the distinction between the transitive life that we call consciousness, and the intransitive life of organisms that merely keep themselves alive. In this text, we put forward the hypothesis that this neutrality, far from being a simple accident of language, is highly revealing as to the primordial status of life; it thus indicates the direction that a phenomenology of life should take. The question that a phenomenology of life has to confront is thus the following: what is the primordial meaning of life such that it precedes the distinction between intransitive and transitive life, and thereby makes this distinction possible? In other words: what is life such that the possibility of consciousness is grounded therein? From the moment we consider that consciousness is basically characterized by intentionality, primordial life must already contain the germ of a fundamental transitivity where intentionality can be grounded; it follows from this that the question of the Being of intentionality, and that of the mode of Being of life, are one and the same question.

All organisms behave, but, as far as we know, only humans also explain behavior. Organisms routinely destroy other organisms for various reasons, but only humans ask why. One answer is “hatred.” Clearly it is not necessary to hate another organism in order to destroy it, but the idea is commonly invoked as an explanation for human violence. Has this always been the case with us humans? Or is “hate” (and other explanations of behavior) some kind of evolutionary adaptation? If so, what kind of evolution is involved in the development of explanations, and how might they serve to support individual and/or species survival? In other words, what are some of the epistemological roots of “hate” and what are some of the ontological’ consequences of constructing such an explanation?

In this article I will outline the basic theoretical assumptions of two examples of the confederative and the integrative views of the living – respectively Ganti’s Chemoton theory and Maturana and Varela’s autopoietic theory – by showing that they are both consistent perspectives, but they differ in the accounts they make of the role of organization in biological systems. In doing so I will also put into evidence how the choice between these two theoretical frameworks is strictly connected to the problem of structure and function in living organisms and entails different strategies of investigation.

Key words: biological autonomy, organization, autopoiesis, Chemoton theory

Excerpt: From 1949 onwards, Grey Walter built several intriguing cybernetic machines. These were intended to throw light on the behaviour of biological organisms – although he did point out that they could be adapted for use as ‘a better “self-directing missile”’… In particular, Grey Walter sought to model goal seeking and, later, learning. But he did so as economically as he could – in both the financial and the theoretical sense. Not only did he want to save money (the creatures were cobbled together from war-surplus items and bits of old alarm clocks), but he was determined to wield Occam’s razor. That is, he aimed to posit as simple a mechanism as possible to explain apparently complex behaviour.

Embodied cognition (EC) views propose that cognition is shaped by the kind of body that organisms possess. We give an overview of recent literature on EC, highlighting the differences between stronger and weaker versions of the theory. We also illustrate the debates on the notions of simulation, of representation, and on the role of the motor system for cognition, and we address some of the most important research topics. Future challenges concern the understanding of how abstract concepts and words are represented, and the relationship between EC and other promising approaches, the distributional views of meaning and the extended mind views.
