    Core Enaction presentation on September 28, 2022:
    “Francisco Varela’s Cybernetic Genealogy from the Biological Computer Lab to the Systems Counterculture”

    This presentation will focus on Francisco Varela’s relation to the seminal cyberneticist Heinz von Foerster. For Varela, von Foerster was both a mentor from whose work he drew support and inspiration for his own scientific projects, and a sponsor who promoted Varela’s career, especially during the difficult years of Varela’s exile from Pinochet’s Chile during the 1970s. To appreciate the depth of this relationship, we will review von Foerster’s own precarious progress toward a scientific career as an Austrian survivor of Nazi Germany whose emigration to the US and academic establishment at the University of Illinois were strongly assisted by one of the key figures of the original cybernetics, the psychiatrist and brain scientist Warren S. McCulloch. McCulloch not only helped von Foerster to gain academic employment in the US at the turn of the 1950s, but also drew him into the ongoing series of Macy Conferences on Cybernetics, for which McCulloch was the director. By this singular stroke of good fortune, von Foerster found himself in the company of formidable thinkers from Norbert Wiener, Claude Shannon, and John von Neumann to Gregory Bateson and Margaret Mead. Moreover, with collaborator Walter Pitts, McCulloch developed a method of doing cognitive science that he termed experimental epistemology, a kind of mathematical neurophysiology that would be carried forward by von Foerster at his Biological Computer Lab (BCL), established in 1958, and then by Varela in his development toward The Embodied Mind. The other key connection here was Humberto Maturana’s collaboration with McCulloch at MIT and subsequent close connections with von Foerster. Thus, as Maturana and Varela were developing the first drafts of the autopoiesis concept, von Foerster was one of its first readers and most stalwart supporters. And once Heinz and Francisco had established their own intellectual conversation, they found a mutual enthusiasm for George Spencer-Brown’s Laws of Form and the related discourses of recursion and self-reference we now associate with the emergence of second-order cybernetics. Through von Foerster’s connections with the systems counterculture centered around Stewart Brand’s CoEvolution Quarterly, during Varela’s American sojourn in the mid-to-later 1970s, he reached the eclectic audiences that received his seminal early statements, such as “A Calculus for Self-Reference,” “On Observing Natural Systems,” and “Not One, Not Two,” on the way to his first masterwork, Principles of Biological Autonomy. Throughout this period as well, he collaborated with von Foerster on projects related to their shared convictions regarding the ethics of epistemological constructivism.

    Session 3: “The Cybernetic Origins of the Enactive Approach” by Dr Juan Carlos Letelier

    In this session, we will review: a) the early history of the concept of autopoiesis, b) the early contributions of Francisco Varela toward simulating and formalizing metabolic closure and self-reference. The crucial years (1968-1974) will be presented with some detail, like the Technical Report #9 (Biology of Cognition, by Maturana) including some unique moments like the famous project SYNCO or the “best course on Cybernetics” which was given in July 1973 at Santiago by von-Foerster, Maturana, Varela and others in the context of project SYNCO. The impact of  the years 1974-1980 will also be analyzed as well as the 1980-1984 period when Varela returned to Chile and published, with Maturana, the first edition of the The Tree of Knowledge. Also we will focus on his research concerning neuroscience, in particular his fundamental (and unrecognized) contributions to the idea of neural synchronization and the science of consciousness studies. Varela was instrumental in developing tools to measure neural synchronization and, little by little, he morphed his mathematical analysis into a conception of “perceptual frames”. Varela used a great part of his stay at Paris (as a CNRS researcher) trying, before almost anyone else, to mix modern quantitative neuroscience with contemplative studies. A fundamental aspect of his (and Maturana´s) research was concerned about how living systems create the objects they encounter in their world. For this creation they used different words, Enaction (in the case of Varela) and Structural Coupling (in the case of Maturana).  Both concepts are similar and are also related to more classic concepts like Umwelt (von-uexkull) and affordances (Gibson). Interestingly, all these ideas can be expressed in terms of autopoietic networks interacting with their medium using Bayesian inference.

    Session 4: “Autopoiesis” by Dr Tom Ziemke

    The lecture discusses the concept of autopoiesis, its different interpretations, and the connections to related concepts and theories that came before and after. More specifically, we will discuss work in philosophy and theoretical biology (Kant, von Uexküll, Jonas), work on computational models of autopoiesis (e.g., McMullin, Beer), and recent work in cognitive science (e.g., Bickhard).

    Session 5: “Autopoiesis” by Dr Juan Carlos Letelier

    Watch the recording here!

    In this session, Dr. Juan Carlos Letelier will review the initial core problem: to understand metabolism and to understand metabolic stability. A review of the modern attempt at mixing autopoiesis and various ideas will be provided. A special chapter will explain the cryptic ideas from Robert Rosen and their unexploited potentialities. Also, he will confront the various metaphorical usages of the concept of Autopoiesis ranging from the AUTOPOIESIS OF LAW to the AUTOPOIESIS OF WARFARE. Dr. Letelier will introduce the concept of STRUCTURAL COUPLING, an idea that he thinks is central to the overall theory. As this is a mysterious idea he will spend some time explaining it. Finally, in another mysterious “coup de main” he will discuss a fundamental idea about language.
