Abstract

Open peer commentary on the article “Homeostats for the 21st Century? Simulating Ashby Simulating the Brain” by Stefano Franchi. Upshot: The target article proposes that Ashby’s investigations of the homeostat and ultrastability lead to a view of living systems as heteronomous, passive “sleeping” machines and thus are in fundamental conflict with concepts of autonomy developed by Jonas, Varela and others. I disagree, arguing that (1) the maintenance of essential variables within viability limits is not a passive process for living systems and (2) the purpose of Ashby’s investigations of the homeostat was to investigate adaptivity, a subject that is related to, but clearly distinct from, autonomy. As such, I find Ashby’s work on adaptivity to be neither in opposition to nor in direct support of modern concepts of biological autonomy and suggest that a productive way forward involves the investigation of the intersection between these two fundamental properties of living systems.
