This article considers W. Ross Ashby’s ideas on the nature of embodied minds, as articulated in the last five years of his career. In particular, it attempts to connect his ideas to later work by others in robotics, perception and consciousness. While it is difficult to measure his direct influence on this work, the conceptual links are deep. Moreover, Ashby provides a comprehensive view of the embodied mind, which connects these areas. It concludes that the contemporary fields of situated robotics, ecological perception, and the neural mechanisms of consciousness might all benefit from a reconsideration of Ashby’s later writings.

Recent work on the fundamental processes of regulation in biology (Ashby, 1956) has shown the importance of a certain quantitative relation called the law of requisite variety. After this relation had been found, we appreciated that it was related to a theorem in a world far removed from the biological – that of Shannon on the quantity of noise or error that could be removed through a correction-channel (Shannon and Weaver, 1949; theorem 10). In this paper I propose to show the relationship between the two theorems, and to indicate something of their implications for regulation, in the cybernetic sense, when the system to be regulated is extremely complex.

Purpose: The purpose of this paper is to propose a model of education that is non-reproductive; that is, productive of non-trivial machines. The reason for this is the postulate that society’s main problems are second-order deficiencies, which cannot be fixed by doing what we do better or more intensely, but rather by changing what we do. Design/methodology/approach – This paper proposes several guidelines for non-reproductive education based on Von Foerster’s concept of a non-trivial machine and of legitimate questions, and Ashby’s law of requisite variety. The ideas presented are corollaries and the result of a philosophical fleshing-out of said concepts and laws. Findings: In order to have a non-reproductive education, it is necessary to limit the role of central control and promote self-evaluation in education at every level of recursion: that is, in the relationship between state and educational institutions, educational institutions and teachers, teacher and students and students as evaluators of themselves. Originality/value – First, the concept of genuine self-evaluation is proposed, to distinguish this from what is currently called self-evaluation; which, it is shown, is not truly so. Second, the concept of authentic research is proposed, as distinguished from original research. This is useful for seeing how legitimate questions work at all levels of education. Third, a number of relationships between cybernetics and philosophical thought are established. Fourth, a model for non-reproductive education is proposed.

W. Ross Ashby was a founder of both cybernetics and general systems theory. His systems theory outlined the operational structure of models and observers, while his cybernetics outlined the functional architecture of adaptive systems. His homeostat demonstrated how an adaptive control system, equipped with a sufficiently complex repertoire of possible alternative structures, could maintain stability in the face of highly varied and challenging environmental perturbations. The device illustrates his ‘law of requisite variety’, i.e. that a controller needs at least as many internal states as those in the system being controlled. The homeostat provided an early example of how an adaptive control system might be ill-defined vis – vis its designer, nevertheless solve complex problems. Ashby ran into insurmountable difficulties when he attempted to scale up the homeostat, and consequently never achieved the general purpose, brainlike devices that he had initially sought. Nonetheless, the homeostat continues to offer useful insights as to how the large analogue, adaptive networks in biological brains might achieve stability.

Ashby’s Law of Requisite variety, Beer’s Viable System Model, Maturana’s Biology of Cognition, Habermas’s theory of communicative action and Luhmann’s theory of social systems have assisted my reflections upon issues such as power, democracy, participation and fairness in society. I have explored these issues from a cybernetics perspective in several publications (Espejo, 2001a, 2001b, 2004) and they remain a central concern of my current work on nuclear waste management in Europe.

This article discusses the explanatory paths that Maturana calls objectivity-without-parenthesis, or the path of transcendental objectivity, and the path of objectivity-in-parenthesis, or the path of constituted objectivity (Maturana, 1988). I relate these views to Black Box descriptions and operational descriptions of organizational systems (Espejo & Reyes, 2011). The most significant implication of this distinction is that while Black Box descriptions are focused on the relational complexity of the social system with its environment, the operational descriptions are focused on the complexity of the relationships producing these organizational systems from the multiple stakeholders’ viewpoints, accounting for aspects such as respect, trust, collaboration, cooperation and in more general terms to the emotions of love constituting these relationships. It is argued that this second-order cybernetics perspective is complementary to the first order, Black Box perspective, and adds to our understanding of Ashby’s requisite variety (Ashby, 1964) and Beer’s viable system model (Beer, 1979).

In marketing theory, the shift from the paradigm of value creation to value ‘cocreation’ calls for a deeper grasp of the interactions between producers and customers. Marketing studies have widely focused on the value cocreation concept, but so far, the mechanism through which consumers can be involved in the process of value cocreation through product development had found little space in marketing studies. In this theoretical paper, we aim to fill this gap and pave the way towards a better understanding of the mechanisms of value cocreation for product development through second-order cybernetics. We conceive the market arena as a physical or virtual place where communications of value propositions produce eigenforms driving the eigenbehaviours of producers and customers towards shared meaningful objects. Based on these assumptions, we offer a framework based on the viable systems model and the law of requisite variety to shed light on processes of interaction between producers and consumers in the market arena. The proposed framework can be an effective tool for the managers involved in product design and marketing to contribute to a firm’s policies by supplying a clearer picture of the systemic relations involved in the value cocreation for product innovation and product development.

Purpose Autopoiesis is a concept originally used to define living systems. However, no measure for autopoiesis has been proposed so far. Moreover, how can we build systems with a higher autopoiesis value The paper aims to discuss these issues. Design/methodology/approach: Relating autopoiesis with Ashby’s law of requisite variety, self-organization is put forward as a way in which systems can be designed to match the variety of their environment. Findings: Guided self-organization has been shown to produce systems which can adapt to the requisite variety of their environment, offering more efficient solutions for problems that change in time than those obtained with traditional techniques. Originality/value: Being able to measure autopoiesis allows us to apply this measure to all systems. More “living” systems will be fitter to survive in their environments: biological, social, technological, or urban.

Key words: Adaptation, Autopoiesis, Self-organization

Excerpt: What I want to show is that, whereas Ashby’s Law of Requisite Variety is usually interpreted as placing a difficult condition on us, there is another way of looking at this law that treats it as (amongst other things) the source of creativity. Just how difficult it is to satisfy the Law is the first thing I show in exploring transcomputability limits and how we have traditionally overcome these (thus satisfying the Law). I then introduce this idea that we do not have to satisfy the Law, and indicate how it works in offering increased variety and, hence, a (potential) improvement in creativity, citing our interaction with the World Wide Web as an example.

In this article I explore, from a cybernetic point-of-view, the associated notions of com-plexity, unmanageability, conversation and trust. Complexity is familiarly presented as a problem of our time. I argue that, when seen through the characterisations of the cyber-netic Law of Requisite Variety, complexity often leads to unmanageability, characterised by a controlling system not having enough variety to control the system it is to control. This leaves two options: to reduce the complexity of the system to be controlled (the option used by dictators controlling peoples), or to admit unmanageability. It is argued that unmanageability can be desirable in offering access to novelty. It is then argued that the primary means by which we can interact (and thus affect the behaviour of another system) should be seen as the conversation rather than encodement. (The alternative, to find another way in which to think of the system displaying complexity is also discussed.) The conditions that support conversation are explored: in particular, the im-plicit obligation to trust other participants in a conversation – and oneself. Trust is considered, and its benefits extolled against a background of experience in a historical context.
