He argues that emergent complexity relies on a type of downward causality that doesn't exist. The building blocks of emergent systems, like neurons or ants, remain simple and unchanged despite the complexity that emerges from their interactions.
He means that the higher-level properties that emerge from simple components do not influence those components in a way that changes their basic nature. For example, a complex ant society doesn't make individual ants smarter; they remain simple and unchanged.
Epigenetics provides a mechanism for how early life experiences influence who we become, but it doesn't allow for conscious choice to reverse or change those effects. It functions within the rules of simple, deterministic interactions.
Unpredictability is due to the complexity and randomness in systems, not because individuals have control over their actions. Randomness, whether from quantum mechanics or other sources, introduces variability but doesn't confer responsibility or control.
He finds the argument based on intuition the most frustrating. People often insist that it feels like they have free will when making decisions, despite understanding the deterministic nature of their brain's activity.
He finds Dennett's concerns ironic, given Dennett's usual separation of political concerns from truth claims. Sapolsky believes Dennett's arguments conflate the social implications with the philosophical and scientific claims about free will.
Harris uses the analogy of Atlantis, where compatibilists argue that free will is real but redefine it to fit their deterministic view, much like saying Atlantis is real but it's actually Sicily.
He describes how genes and their regulation through epigenetics influence behavior, but this doesn't provide space for free will. The influence is deterministic and doesn't allow for conscious choice to alter genetic outcomes.
Sam Harris speaks with Robert Sapolsky about the widespread belief in free will. They discuss the limits of intuition, the views of Dan Dennett, complexity and emergence, downward causation, abstraction, epigenetics, predictability, fatalism, Benjamin Libet, the primacy of luck, historical change in attitudes about free will, implications for ethics and criminal justice, the psychological satisfaction of punishing bad people, understanding evil, punishment and reward as tools, meritocracy, the consequences of physical beauty, the logic of reasoning, and other topics.
