Key takeaways

Read in full (NOTE-719).

  • Autopoiesis entails conservation, not homeostasis. Allowing no degrees, it admits fortuitous self-maintenance, and its only norm is “organisms live as long as they don’t die”. That norm lets an observer tell lethal from non-lethal encounters; the system cannot.
  • Adaptivity is the missing condition. It is defined as a capacity to regulate states and environmental relations so that, near the viability boundary, tendencies toward it are detected and turned back. It is graded, has no optimum, and is recursive: regulation can be regulated, and adaptive processes can themselves be “plastically adjusted or transformed depending on their effectiveness”.
  • Robust is not adaptive. Minimal autopoiesis models and synthetic vesicles tolerate perturbations without monitoring them; the Chemoton adapts. Illness, stress and fatigue are failures of adaptivity while the system is still autopoietic.
  • Behaviour is the regulation of coupling, not the coupling. An agent regulates its exchanges for its own viability. Agency comes in degrees and is not implied by autopoiesis and adaptivity together.
  • Speculative close: self-sustaining behavioural and social forms may generate values of their own, which can conflict with metabolism (addiction).

Standing in the record

Filed for the will-organization line’s viability claims.

Adaptivity is mostly not CLAIM-025’s transformation capacity. As defined it is regulation against one fixed boundary, closer to an operative regime or its governing organization. Its plastic, second-order layer, and the cure that may “re-define rather than simply restore” a norm (the point of CLAIM-018), come close to transformation capacity, but Di Paolo treats them as aspects of one graded property and never shows them failing separately, so the paper is vocabulary for CLAIM-025, not evidence for it. What it does separate is autopoiesis from adaptivity, a separation of the same shape as CLAIM-099’s one level down. Its bacterium, autopoietic now but on course to die, is CLAIM-079’s case; Di Paolo does not distinguish the viability set from the viability kernel (THEORY-134). His speculative “adaptive closure” of non-metabolic forms is a lead, not an answer, on ARG-007’s mapping premise.

It is not a rival to CLAIM-075. Di Paolo argues that viability alone yields no norm the system has, which is CLAIM-075’s point made more strongly. The norm adaptivity adds is good or bad for the organism, and the paper never says that anything ought to persist. It makes no constitutivist argument about reasons, so Enoch’s shmagency objection (LIT-117, not read) does not bite as the record describes it. One point for CLAIM-075’s wording: Di Paolo’s norm is generated by and accessible to the system, not an observer’s if-then, so “conditional functional judgment” should say which conditionality it means.

Barandiaran, Di Paolo & Rohde on defining agency (LIT-566) take their agency definition from this paper, and De Jaegher & Di Paolo (LIT-571) extend its sense-making to social interaction.
