In neurological language, the primitive neural patterns emerging from the brain stem become "vulcanized" and impede the higher level neural patterns originating in the cortex. ("Vulcanization of neural patterns is modern scientifical talk for "habits." Cf. Cohen, "The Vulcanization of the Human Brain: A Neural Perspective on Interactions Between Cognition and Emotion". Note the emergent Aristotelianism: Cognition and Emotion here coding for Intellect and Will.) But this subordination denies our essence as rational beings in favor of a view of humans as mere bundles of appetites.
