We introduce a spatial model of concentration dynamics that supports the emergence of spatiotemporal inhomogeneities that engage in metabolism–boundary co-construction. These configurations exhibit disintegration following some perturbations, and self-repair in response to others. We define robustness as a viable configuration’s tendency to return to its prior configuration in response to perturbations, and plasticity as a viable configuration’s tendency to change to other viable configurations. These properties are demonstrated and quantified in the model, allowing us to map a space of viable configurations and their possible transitions. Combining robustness and plasticity provides a measure of viability as the average expected survival time under ongoing perturbation, and allows us to measure how viability is affected as the configuration undergoes transitions. The framework introduced here is independent of the specific model we used, and is applicable for quantifying robustness, plasticity, and viability in any computational model of artificial life that demonstrates the conditions for viability that we promote.

An evolving theory known as “constructivism” challenges the traditional view of how we generate and revise knowledge. Constructivism helps address a major issue raised by modern scholars of the history and philosophy of science, and decision theory. The question is: How do we reduce the search and solution space of complex and changing environments to “mind size” (i.e., to fit our limited memory and computational capacity)? One emerging answer is that we rely heavily upon robust presuppositions and simplified representations of environmental structure. However, such constructed knowledge is likely to be highly fallible, relying as it must on impoverished data bases in the service of strong expectations or paradigms. In this paper we address two issues: Under what conditions can knowledge be highly fallible and at the same time be highly functional?; Can we make a plausible case, within this constructivist frame of reference, for realism, for knowledge that approximates “reality”?

The concept of autonomy is of crucial importance for understanding life and cognition. Whereas cellular and organismic autonomy is based in the self-production of the material infrastructure sustaining the existence of living beings as such, we are interested in how biological autonomy can be expanded into forms of autonomous agency, where autonomy as a form of organization is extended into the behaviour of an agent in interaction with its environment (and not its material self-production) In this thesis, we focus on the development of operational models of sensorimotor agency, exploring the construction of a domain of interactions creating a dynamical interface between agent and environment. We present two main contributions to the study of autonomous agency: First, we contribute to the development of a modelling route for testing, comparing and validating hypotheses about neurocognitive autonomy. Through the design and analysis of specific neurodynamical models embedded in robotic agents, we explore how an agent is constituted in a sensorimotor space as an autonomous entity able to adaptively sustain its own organization. Using two simulation models and different dynamical analysis and measurement of complex patterns in their behaviour, we are able to tackle some theoretical obstacles preventing the understanding of sensorimotor autonomy, and to generate new predictions about the nature of autonomous agency in the neurocognitive domain. Second, we explore the extension of sensorimotor forms of autonomy into the social realm. We analyse two cases from an experimental perspective: the constitution of a collective subject in a sensorimotor social interactive task, and the emergence of an autonomous social identity in a large-scale technologically-mediated social system. Through the analysis of coordination mechanisms and emergent complex patterns, we are able to gather experimental evidence indicating that in some cases social autonomy might emerge based on mechanisms of coordinated sensorimotor activity and interaction, constituting forms of collective autonomous agency.

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.

Sensory substitution constitutes an interesting domain of study to consider the philosopher’s classical question of distal attribution: how we can distinguish between a sensation and the perception of an object that causes this sensation. We tested the hypothesis that distal attribution consists of three distinct components: an object, a perceptual space, and a coupling between subjects’ movements and stimulation. We equipped sixty participants with a visual-to-auditory substitution device, without any information about it. The device converts the video stream produced by a head-mounted camera into a sound stream. We investigated several experimental conditions: the existence or not of a correlation between movements and resulting stimulation, the direct or indirect manipulation of an object, and the presence of a background environment. Participants were asked to describe their impressions by rating their experiences in terms of seven possible “scenarios”. These scenarios were carefully chosen to distinguish the degree to which the participants attributed their sensations to a distal cause. Participants rated the scenarios both before and after they were given the possibility to interrupt the stimulation with an obstacle. We were interested in several questions. Did participants extract laws of co-variation between their movements and resulting stimulation? Did they deduce the existence of a perceptual space originating from this coupling? Did they individuate objects that caused the sensations? Whatever the experimental conditions, participants were able to establish that there was a link between their movements and the resulting auditory stimulation. Detection of the existence of a coupling was more frequent than the inferences of distal space and object.

Key words: sensory substitution, distal attribution, space, object, objecthood, sensorimotor theory, sensorimotor coupling.

The notion that human activity can be characterised in terms of dynamic systems is a well-established alternative to motor schema approaches. Key to a dynamic systems approach is the idea that a system seeks to achieve stable states in the face of perturbation. While such an approach can apply to physical activity, it can be challenging to accept that dynamic systems also describe cognitive activity. In this paper, we argue that creativity, which could be construed as a ‘cognitive’ activity par excellence, arises from the dynamic systems involved in jewellery making. Knowing whether an action has been completed to a ‘good’ standard is a significant issue in considering acts in creative disciplines. When making a piece of jewellery, there a several criteria which can define ‘good’. These are not only the aesthetics of the finished piece but also the impact of earlier actions on subsequent ones. This suggests that the manner in which an action is coordinated is influenced by the criteria by which the product is judged. We see these criteria as indicating states for the system, e.g. in terms of a space of ‘good’ outcomes and a complementary space of ‘bad’ outcomes. The skill of the craftworker is to navigate this space of available states in such a way as to minimise risk, effort and other costs and maximise benefit and quality of the outcome. In terms of postphenomonology, this paper explores Ihde’s human-technology relations and relates these to the concepts developed here.

Key words: creativity, radical embodied cognitive science, postphenomonology, jewellery making, dynamic systems, uncontrolled manifold hypothesis.

Excerpt: The world is made up of not only natural kinds but also artefacts, stuff that we human beings, individually or communally, construct. Chairs and tables, airplanes and buildings, are our constructs; they are conceived by individuals or groups and are also built by them. But the scope of our construction is not limited to physical artefacts; the social space is also populated by our constructions. A university, to take but one example, is much more than its buildings, its very existence depends on rules, agreements, conventions, and covenants constructed and entered upon by human beings. It’s our joint intention, persisting through time that gives reality to institutions of higher education and their functioning through time. This much is platitudinous and not seriously in dispute. Major philosophical debates begin firstly when we try to draw a dividing line between natural kinds and artefacts and secondly in any attempt to adjudicate on the ontological status of our social constructs.

Archetypal codes, genetic codes and neural codes represent different levels of illustrating the concepts of consciousness and unconsciousness. Symbolisations taking the form of myths tell us something about the development of the mutual relationship of the two realms. As a third element, myths represent a transitional space located between the individual and the collective. An outline will be given on the approaches developed by Jung, Neumann, Bischof, Jaynes, Singer and Reich. The dramatic increase in replacing natural processes by artificial ones and in the extent to which man is capable of interfering in such processes today leads to a situation where the side of the objects and the objective (as the natural laws that are given) is constantly receding and is thereby strengthening the productive character of the objective: there is no thing-in-itself any more, only its absence or presence. In both quality and quantity, it is the result of a man-made decision. At the same time, the part of the subjective is getting ever more differentiated: it is itself becoming the object of its own productive endeavours and is no longer identical with itself. It achieves its identity by recognizing the other as being different. The author draws up the myth of a ‘Zwitschermaschine’ (twittering machine; Paul Klee, 1922) as a present-day paradigm of intersubjectivity, centering the concepts of self-authorization and autopoiesis as the stock of existing problems: man is becoming an effect of the very discourses he gives on himself.

Key words: myth, archetypical code, autopoiesis, intersubjectivity, self-authorisation

The roles of art, design, and architecture on long-duration human space missions could have deep, significant impact on the functional capabilities of human environments in space, far beyond mere form and aesthetics. Yet, today’s technology-driven paradigm of space design pays limited attention to “soft” disciplines that relate to artistic and designerly modes of operations. This current worldview is governed by engineers and project managers. “Soft” considerations are looked at as nice-to-have add-ons at the end of the project, dependent on resource availability. While sufficient for short missions, this unnecessarily constrained view of artistic and designerly modes must change for long-duration missions, as the crew spends nearly 100% of their time inside a severely limited volume, in virtual isolation. Thus, it becomes necessary for all the systems, usable objects, and artistic artifacts inside the habitat to be connected to the goal of facilitating engaging interactions with the crew. Artifacts – as boundary objects in the intersection of various disciplines – facilitate circular conversations between an observer (crew member) and the environment of the spacecraft, and have many important functions. They provide emotional connections and comfort, promote well-being, support autonomy, help thinking to evolve novel ideas, and aid discovery and entertainment. When designing for experiences and interactions in space, artists, designers, and architects are able to look at artifacts from the perspective of the crew as observers, and imagine a rich set of interactions through various aspects and stages of the spaceflight. As a result, these artifacts support the higher-level needs of the observer, beyond basic physiological, psychological, and safety needs. They are designed for the well-being of the crew members, while sustainably utilizing the habitat volume and resources. In this paper we systematically show how human-centered roles and circular conversations between the observers and their environments can be incorporated into the culture of designing for space travel through the involvement of artists, designers and architects, from an early stage of designing the mission and its elements. This process is inclusive of the people who envision and create the environments and user experiences, and those who experience, use, and evolve them. Making the case about the importance of these considerations may help artists, designers, and architects to reframe the discourse of their contributions to space exploration and, in effect, find a stronger acceptance from the decision makers of a technology-driven human space exploration paradigm.

Living agency is subject to a normative dimension (good-bad, adaptive-maladaptive) that is absent from other types of interaction. We review current and historical attempts to naturalize normativity from an organism-centered perspective, identifying two central problems and their solution: (1) How to define the topology of the viability space so as to include a sense of gradation that permits reversible failure, and (2) how to relate both the processes that establish norms and those that result in norm-following behavior. We present a minimal metabolic system that is coupled to a gradient-climbing chemotactic mechanism. Studying the relationship between metabolic dynamics and environmental resource conditions, we identify an emergent viable region and a precarious region where the system tends to die unless environmental conditions change. We introduce the concept of normative field as the change of environmental conditions required to bring the system back to its viable region. Norm-following, or normative action, is defined as the course of behavior whose effect is positively correlated with the normative field. We close with a discussion of the limitations and extensions of our model and some final reflections on the nature of norms and teleology in agency.
