Piaget defines intelligence as adaptation, or the ability to maintain a balance between stability and change, or, in his own words, between assimilation and accommodation. When people assimilate the world to their current knowledge, they impose their order upon things. This momentary closure is useful to build “invariants” that lend existence to the world, independent of immediate interaction. In accommodation, people become one with the object of attention. This may lead to momentary loss of control, since fusion loosens boundaries, but allows for change. I choose the domain of perspective-taking to illustrate how this alternation between assimilation and accommodation punctuate individuals’ interactions with the world. I show that the ability to move away from one’s own standpoint, and to take on another person’s view, requires the construction of cognitive invariants: a recasting of the world’s stabilities that transcends any given viewpoint. I conclude that separation is a necessary step toward the construction of a deeper understanding, and that adopting a “god’s eyes view” is by no means contrary to situating one’s one stance in the world.

Natural systems cannot be closed to the environment. At the same time there is a necessity for closure in order to build the system. It is this quintessential tension between openness and closure that drives systems to unfold into further stages or levels of growth and development. In other words, the emergence of organization in natural systems is a result of cycles of openness and closure. There are two distinct and complementary ways by which a system will carry over closure while involved in a process of expansion across the environment. These two ways need to be expressed in any formal representation: (1) within a level this will be by means of transitive closure, which is additive; and (2) between levels (i.e., from one level to the next higher level) this requires algebraic closure, which is multiplicative. The former expresses space closure, whereas the latter expresses topological or time closure. The conjunction of these two closures generates a hierarchy of levels. Prior to, and outside of, the system lies semantic closure.

The present paper wants to show the extent to which prosody, or best, prosodies, as Firth (1948) put it, contribute in their own and specific ways to enaction, at various levels of operational closure. On the one hand prosodies (stress, accent, melody) are linked to speech and exchange in a non-escapable fashion, as opposed to gesture for example. Hearing speech implies hearing syllables, tones, intensity variations; it does not imply seeing face or gesture (though one may object the language-dependency of prosody – gesture pairings). Simon & Auchlin (2004) described the independent timings of parameters, such as pitch range, height and intensity, speech rate: the first two or three syllables of speech alone inform on speaker sex, age, mood, investment in speech, importance of speech for her, or intentionality; the meaning of the whole utterance is obtained much later, thus the first flow somehow frames the second which, in turn, may allow blending with previously accessed information. In that way, linguistic meaning incorporates prosodic manifestations. On the other hand, one of the most basic prosodic dimensions, namely speech rate (articulation rate + pauses) is properly speaking a shared dimension between speaker and hearer: no one can hear slowly, or more rapidly than the speaker speaks. Speech rate is properly un-escapable, or necessarily shared dimension in dialogue. Indeed, interpreting is constantly anticipating – but anticipations timing still depends upon speech rate. Note that speech rate is also un-escapable for the observer, provided (s) he enacts the discourse, turning herself into a participant in the piece of interaction (s) he wants to describe (Auchlin, 1999). Sharing the temporal grid, i. e. entering it, is essential to such now. Indeed, interactionists’ work (P. Auer, E. Couper-Kuhlen, F. Müller; M. Selting; J. Local, i. a.) precisely describe verbal interactions’’ ballet temporality. Yet, their descriptive claim, which constrains empirical work, deliberately rejects any kind of theoretical conclusion or generalization; and their need to '‘objectively’’ describe speech events firmly contradicts what is mandatory for the enactive approach, namely the epistemological experientialist turn, first posited by Lakoff & Johnson (1980). The present paper examines a couple of emblematic cases of prosodic enacting meaning experience that should contribute to grounding the concept, both on its epistemological and its empirical sides.

Self-referential systems theory does not provide for a concept of intelligence. There is even a certain resistance to intelligence that seems to block any explicit exchange of concepts with artificial systems theory. The paper describes the intelligence service in self-referential systems as the self-referential and, hence, paradoxical switching from the self-reference of these systems to other-reference. How this might work is shown by means of G. Spencer Brown’s calculus of indications and Heinz von Foerster’s notion of double closure.

It is characteristic of Heinz von Foerster’s approach to the cybernetics of cybernetics that it combines a sense of tight reasoning with the acknowledgment of fundamental ignorance. The article attempts to uncover an epistemological relationship between the reasoning and the ignorance. The relationship is provided for by a razor which reads: what can be described in relation to its composition, is described in vain in relation to its substance. The razor asks for second-order terms instead of first-order terms, or for ontogenetics instead of ontology.

The paper recalls some skeptical comments Norbert Wiener made regarding the potential use of cybernetics in social sciences. A few social scientists were seduced by cybernetics from the beginning, but cybernetics never really caught on in sociology. The paper argues that one reason for this may lie in the mathematical theory of communication entertained by early cybernetics. This theory which maintains that there are probability distributions of possible communication is at odds with the sociological theory’s idea of a communication driven by improbable understanding. Yet the move from first-order cybernetics to second-order cybernetics, by re-entering the observer into the very systems she observes, provides for a bridge between cybernetics and sociology.

The concept of “autonomy,” once at the core of the original enactivist proposal in The Embodied Mind (Varela et al. in The embodied mind: cognitive science and human experience. MIT Press, Cambridge, 1991), is nowadays ignored or neglected by some of the most prominent contemporary enactivists approaches. Theories of autonomy, however, come to fill a theoretical gap that sensorimotor accounts of cognition cannot ignore: they provide a naturalized account of normativity and the resources to ground the identity of a cognitive subject in its specific mode of organization. There are, however, good reasons for the contemporary neglect of autonomy as a relevant concept for enactivism. On the one hand, the concept of autonomy has too often been assimilated into autopoiesis (or basic autonomy in the molecular or biological realm) and the implications are not always clear for a dynamical sensorimotor approach to cognitive science. On the other hand, the foundational enactivist proposal displays a metaphysical tension between the concept of operational closure (autonomy), deployed as constitutive, and that of structural coupling (sensorimotor dynamics); making it hard to reconcile with the claim that experience is sensorimotorly constituted. This tension is particularly apparent when Varela et al. propose Bittorio (a 1D cellular automata) as a model of the operational closure of the nervous system as it fails to satisfy the required conditions for a sensorimotor constitution of experience. It is, however, possible to solve these problems by re-considering autonomy at the level of sensorimotor neurodynamics. Two recent robotic simulation models are used for this task, illustrating the notion of strong sensorimotor dependency of neurodynamic patterns, and their networked intertwinement. The concept of habit is proposed as an enactivist building block for cognitive theorizing, re-conceptualizing mental life as a habit ecology, tied within an agent’s behaviour generating mechanism in coordination with its environment. Norms can be naturalized in terms of dynamic, interactively self-sustaining, coherentism. This conception of autonomous sensorimotor agency is put in contrast with those enactive approaches that reject autonomy or neglect the theoretical resources it has to offer for the project of naturalizing minds.

Open peer commentary on the article “Interactivity and Enaction in Human Cognition” by Matthew Isaac Harvey, Rasmus Gahrn-Andersen & Sune Vork Steffensen. Upshot: To sort out their differences with enactive theory, interactivity theorists would do better to focus on operational closure only insofar as it constitutes a condition of intrinsic normativity or self-regulated coupling.

The attempt to define living systems in terms of goal, purpose, function, etc. runs into serious conceptual difficulties. The theoretical biologists Humberto Maturana and Francisco Varela realized that any such attempt cannot capture what is distinctive about them: their autonomy and unity. Goal, purpose, etc. always define the system in terms of something extrinsic, whereas living systems are unique because they maintain their unitary continuity of pattern despite the ceaseless turnover of their components. So, system-closure is a prerequisite of their adequate conceptual comprehension. Maturana and Varela themselves found that system-closure pertains exclusively to their organization, i.e. the set of relations among system-components which unify them. For living systems this comprises the relation between the system-components and the processes which they undergo. This relation is self-referential because it is closed, i.e. it essentially (re)produces itself. \\While this model worked very well in the biological domain, attempts to extend it to the social domain met with serious conceptual obstacles. The reason for this is that Maturana did not make a consistent enough application of it. He understood the components of social systems biologically (individuals, persons, etc.) and the relations between them socially (language). This inconsistency ruptured the system’s organizational closure. Consequently organizational closure (autopoiesis) can be maintained only when both the components of social systems and their processes are of the same type: social. This interpretation can be found in the work of Niklas Luhmann who recognizes that the components of social systems are not persons, individuals, actors or subjects but communicative actions themselves. This preserves the organizational closure of the system and permits the concept of autopoiesis to be used as a powerful instrument of social analysis.

The aim of this paper is to present some system-theoretical notions – such as constraint, closure, integration, coordination, etc. – which have recently raised a renovated interest and have undergone a deep development, especially in those branches of philosophy of biology characterized by a systemic approach. The implications of these notions for the analysis and characterization of self-maintaining organizations will be discussed with the aid of examples taken from models of minimal living systems, and some conceptual distinctions will be provided. In the last part of the paper the epistemic implications of these ideas will be presented.
