R.I.P. Francisco Varela (1946-2001) . John Brockman describes him on The Edge:
‘Francisco, an experimental and theoretical biologist, studied what he termed “emergent selves” or “virtual identities.” His was an immanent view of reality, based on metaphors derived from self-organization and Buddhist-inspired epistemology rather than on those derived from engineering and information science. He presented a challenge to the traditional AI view that the world exists independently of the organism, whose task is to make an accurate model of that world — to “consult” before acting. His nonrepresentationalist world — or perhaps “world-as-experienced” — has no independent existence but is itself a product of interactions between organisms and environment. He first became known for his theory of autopoiesis (“self production”), which is concerned with the active self-maintenance of living systems whose identities remain constant while their components continually change. Varela is tough to categorize. He was a neuroscientist who became an immunologist. He was well informed about cognitive science and was a radical critic of it, because he was a believer in “emergence” — not the vitalist idea promulgated in the 1920s (that of a magical property that emerges inexplicably from lower mechanical operations) but the idea that the whole appears as a result of the dynamics of its component parts. He thought that classic computationalist cognitive science is too simplemindedly mechanistic. He was knowledgeable and romantic at the same time.’
