The Physical Essence of Human Behavior: Deductions Based on the Operating Mechanism of the Brain

This paper proceeds from the physical definition of the brain to deduce that the core concepts of human behavior can be unified under a single physical mechanism. The brain is the physical region with the densest low-resistance pathways left by the history of charge flow; memory is the low-resistance pathways themselves. A person's life is a life in which charge repeatedly flows along already-carved low-resistance pathways within the carbon-based carrier. What we call behavior is the process of charge surging out from dense nodes and flowing along motor branches to the limbs. What we call choice is charge automatically selecting the branch with the lowest resistance at a node. This paper projects this physical fact layer by layer onto eight core concepts—personality, habit, addiction, trauma, love, hatred, choice, and destiny—pointing out that these phenomena, which appear disordered and governed by free will, are essentially all inevitable manifestations of charge passively flowing along low-resistance pathways. This paper does not rely on concepts from psychology, sociology, or philosophy, but proceeds solely from the physical essence of the brain to provide a self-consistent physical language for human behavior.
