The paper compares social systems theory and social network theory in terms of what it is they respectively seek to elucidate. Whereas systems theory focuses on problems of difference and reproduction, network theory deals with problems of identity and control, the former privileging communication and the latter action. To understand their different foci, it may help to keep in mind that systems theory is a child of computing’s formative years, whereas the more recent success of network theory, despite its roots in a far older tradition, accompanies the advent of the Internet. The paper goes on to compare the two theories with respect to questions of mathematical modeling, culture, and self-reference, which interestingly are closely related. It proposes a mathematical modeling of culture, which uses Spencer-Brown’s notion of form to combine variables of communication, consciousness, and life into one network relying on three systems capable of reproducing themselves. The paper is relevant for constructivist approaches because it shows how systems are constructed relying on networks within their own interpretation as culture.

The paper deals with Aristotelian logic as the special case of more general epistemology and sociology of both science and common sense. The Aristotelian principles of identity, of noncontradiction, and of excluded middle are to be supplemented by the secondorder cybernetic, or cybernEthic principles of paradox, of ambivalence, and of control. In this paper we collect some ideas on how to evaluate the scope of Aristotelian logic with respect to the laws of thought they tried to determine and to do so within the historical moment of the impact of the invention of writing possibly triggering this determination. We look at some modern doubts concerning these laws and discovering an understanding of complexity that is not to be resumed under any principle of identity. The invention of sociology, epistemology, and the mathematics of communication follow suit in focusing not only on the observer but more importantly on the distinction between observers to further contextualize any talk of identities and operationalize both talk and fact of contradiction, paradox, and ambivalence.

The paper is a reading of Martin Heidegger’s Contributions to Philosophy (Of the Even) by means of Ranulph Glanville’s notions of black box, cybernetic control and objects as well as by George Spencer-Brown’s notion of form and Fritz Heider’s notion of medium. In fact, as Heidegger was among those who emphasized systems thinking as the epitome of modern thinking, did in his lecture on Schelling’s Treatise on the Essence of Human Freedom a most thorough reading of this thinking, and considered cybernetics the very fulfilment of modern science it is interesting to know whether second-order cybernetics, as it was not known to Heidegger and as it delves into an understanding of inevitable complexity and foundational ignorance, falls within that verdict mere modernity or goes beyond it. If modern science in its rational understanding considers its subjects to be objects sitting still while being observed, then indeed second-order cybernetics is different. It looks into the observer’s interactions with black boxes, radically uncertain of where to expect operations of a self, but certain that we cannot restrict it to human consciousness.

Self-reference and recursion characterize a vast range of dynamic phenomena, particularly biological automata. In this paper we investigate the dynamics of self-referent phenomena using the Extended Calculus of Indications (ECI) of Kauffman and Varela, who have applied the ECI to mathematics, physics, linguistics, perception, and cognition. Previous studies have focused on the algebraic structure of the ECI, and on form dynamics using only the arithmetic of Spencer-Brown. We here examine the temporal behavior of self-referent or reentrant forms using the full power of the ECI to represent tangled hierarchies and multiple enfolded dimensions of space-time. Further, we explore the temporal convolution of static and recursive states in coherent fluctuation, providing a foundation for going beyond the Turing model of computation in finite automata. Novel results are presented on the structure of reentrant forms and the canonical elements of form eigenbehavior, the characteristic self-determined dynamic inherent in reentrant forms.

The present issue is a memorial issue for Francisco Varela both as a scholar and as a colleague. Varela passed away in his home in Paris on May 28 2001. He was part of the editorial board of this journal and thus in this memorial issue we would like to look into his heritage. Most of the papers we present have authors that have known and worked with Varela in some period of their and his life: Ranulph Glanville, Louis Kauffman, Andreas Weber. Weber makes the case that Varela’s thinking can provide a foundation for biosemiotics and as such it provides a further foundation for the cybersemiotic project. Most interesting and promising is his comparison with Varela’s concept of the organism and Bruno Latour’s concept of quasi-objects. The other articles all have some relationship to Varela’s elaboration on the work of Spencer-Brown. Using the metaphor of the Uroboros, Marks-Tarlow, Robertson, and Combs explore the notion of re-entry in Varela’s ‘A Calculus for Self-Reference ’ and his contribution to a theory of consciousness. In their articles, Glanville and Kauffman reflect upon their experience working with Varela on joint papers.

This article praises the development of second-order cybernetics by von Foerster, Maturana and Varela as an important step in deepening our understanding of the biopsychological foundation of the dynamics of cognition and communication. Luhmann’s development of the theory into the realm of social communication is seen as a necessary and important move. The differentiation between biological, psychological and socialcommunicative autopoiesis and the introduction of a technical concept of meaning is central. Furthermore, Varela’s development of Spencer Brown’s ‘Laws of Form’ from a dual to a triadic categorical basic structure is considered vital. Finally the paper shows that second-order cybernetics lacks explicit and ontological concepts of emotion, meaning and a concept of signs. C. S. Peirce’s theory is introduced for this purpose. It is then shown that both theories are triadic and second order, and therefore can be fruitfully fused to a cybersemiotics.

This article praises the development of second order cybernetics by von Foerster, Maturana, and Varela as an important step in deepening our un- derstanding of the bio-psychological foundation of the dynamics of information, cognition, and communication. Luhmann’s development of the theory into the realm of social communication is seen as a necessary and important move. The triple autopoietic differentiation between biological, psychologi- cal, and social-communicative autopoiesis and the introduction of a technical concept of meaning is central. Finally, the paper shows that second order cybernetics lacks explicit and ontological concepts of emotion, meaning, and a concept of signs. C. S. Peirce’s theory is introduced for this purpose. It is then shown, through Varela’s development of Spencer Brown’s ‘Laws of Form’ from a dual to a dynamic triadic categorical structure, that both theories are triadic and second order, and therefore can be fruitfully fused to a Cybersemiotics.

Luhmanian sociocybernetics is an observation of socio-communicative systems with a specific difference. It is a second order observation of observations understanding society as being ‘functionally differentiated’ into autonomous autopoietic subsystems or meaning worlds in the symbolic generalized media such as money, power, truth, love, art and faith. Only communication communicates and the social is communication. The social system creates products of meaning which do not represent an aggregation of the content of individuals’ minds. The bioand psychological autopoietic systems only establish boundary conditions for the sociocommunicative systems, they do not control the socio-communicative system in any way. Somehow the socio-communicative systems seem to develop on their own (by will?) although they have no body and no subject. The psychic system in Luhmann’s theory is thus not a Kantian or Husserlian transcendental ego in spite of Luhmann’s use of aspects of Husserl’s phenomenology (while at the same time destroying its philosophical frame). On the other hand, Luhmann works with an open ontology, combined with Spencer-Brown’s philosophy that making distinctions is what creates the difference between system and environment. Thus observation is basic to the theory-but where is the observer in the theoretical framework of system theory? The inspiration from Hegel is hidden here, where distinction, creation and evolution merge. Also, Hegel has been taken out of his metaphysical frame while Luhmann never took the time to finish his own. On the other hand, the father of the pragmatic triadic semiotic C. S. Peirce-also inspired by Hegel-explicitly confronted some of these problems. Like Bataille, Peirce sees a continuity between mind and matter and his Firstness contains pure feeling, meaning that there is also an inner experience aspect of matter. The article compares Luhmann’s and Spencer-Brown’s strategies with Peirce’s, the latter of whom built an alternative transdisciplinary theory of signification and communication based on a Panentheistic theory of knowing. Surprisingly it fits well with Spencer-Brown’s metaphysics, which makes it possible to establish a consistent foundation for system theory.

Context: Radical constructivism claims that we have no final truth criteria for establishing one ontology over another. This leaves us with the question of how we can come to know anything in a viable manner. According to von Glasersfeld, radical constructivism is a theory of knowledge rather than a philosophy of the world in itself because we do not have access to a human-independent world. He considers knowledge as the ordering of experience to cope with situations in a satisfactory way. Problem: Von Foerster and Krippendorff show that the central goal of a constructivist theory of knowing must be to find a way of putting the knower into a known that is constructed so as to keep the knower, as well as the knowing process, viable in practice. Method: The conceptual and philosophical analysis of present theories and their necessary prerequisites suggests that such foundation for viable knowing can be built on the analysis of what the ontological prerequisites are for establishing viable observing, cognition, communication and observer-communicators, and communication media and vehicles. Results: The moment an observer chooses to accept his/her own embodied conscious presence in this world as well as language, he/she must accept other humans as partly independently existing conversation partners; if knowledge and knowing has to make sense, he/she must also accept as prerequisites for our observation and conversation a pre-linguistic reality from which our bodies come and which our conversation is often about. Furthermore, we can no longer claim that there is a reality that we do not know anything about: From being here in conversation, we know that the world can produce more or less stable embodied consciousnesses that can exchange and construct conceptual meanings through embodied conversations and actions that last over time and exist in space-time and mind, and are correlated to our embodied practices. We can also see that our communication works through signs for all living systems as well as in human language, understood as a structured and progressively developed system of communication. The prerequisite for this social semiotic production of meaning is the fourfold “semiotic star of cybersemiotics,” which includes at least four different worlds: our bodies, the combination of society, culture and language, our consciousness, and also an outer nature. Implications: The semiotic star in cybersemiotics claims that the internal subjective, the intersubjective linguistic, our living bodies, and nature are irreducible and equally necessary as epistemological prerequisites for knowing. The viable reality of any of them cannot be denied without self-refuting paradoxes. There is an obvious connectedness between the four worlds, which Peirce called “synechism.” It also points to Peirce’s conclusion that logic and rationality are part of the process of semiosis, and that meaning in the form of semiosis is a fundamental aspect of reality, not just a construction in our heads. Erratum: The paper erroneously refers to “pleroma.” The correct term is “plemora.”

Upshot: Emergence and Embodiment is a highly worthwhile and well-crafted collection of essays on second-order cybernetics that draws together ideas related to self-organization, autopoiesis, organizational closure, self-reference, and neurophenomenology. Chapters include articles by Heinz von Foerster, Francesco Varela, Niklas Luhmann, George Spencer-Brown, and Evan Thompson and external commentaries on them that analyze the relevance of their ideas in the context of social and cultural theory. Despite some projective distortions to cybernetics that arise from the internal imperatives of culture criticism, the book contains many valuable insights and analyses of core ideas of cybernetics that significantly advance our understanding of them.
