The Unit of Mind Is the Circuit

Bateson's most radical epistemological claim is that mind does not reside inside the individual organism but occurs in the circuit — the complete feedback loop connecting organism to environment and back again. The blind person's stick is part of the mind. The pencil and paper of the writer is part of the mind. Cut the circuit at any point and you cut the mind. This is not metaphor but rigorous claim about where the boundaries of mental process actually fall. For the AI age, the framework dissolves the sterile debate about whether AI 'really thinks': the question is whether the circuit that includes human and AI exhibits the formal properties of mental process — processing differences, feedback loops, self-correction, learning, multiple levels of abstraction. The answer is clearly yes.
