Free will is scientifically impossible | Robert Sapolsky, Paul Bloom, and Lucy Allais

Perspectives on Free Will and Determinism

• 💡 The discussion explores the fundamental question of whether free will exists or if our actions are entirely determined by prior causes.
• 🧠 Paul Bloom suggests that while our mental life is a product of physical brains and behaviors are results of causal forces (materialism and determinism), we still possess the capacity for conscious choice.
• 🎯 Robert Sapolsky firmly believes there is no free will whatsoever, arguing that everything is predetermined by a chain of antecedent causes.
• 💬 Lucy Allais posits that free will is primarily a philosophical question concerning agency, rather than solely a scientific one.

Compatibilism vs. Hard Determinism

• ✅ Bloom, identifying as a compatibilist, argues that even in a determined universe, intentional actions are real and subject to moral judgment, praise, and blame.
• ⚠️ Sapolsky, a hard determinist, explains behavior through a comprehensive chain of antecedent causes, ranging from neuronal activity and environmental stimuli to hormone levels, life experiences, ancestral cultures, and evolution.
• 🔬 Sapolsky asserts that there are no cracks in the deterministic edifice, dismissing arguments for free will based on concepts like quantum indeterminism or chaoticism.

Philosophical Interpretation of Science and Agency

• 🧩 Allais critiques an unnecessarily reductivist view of physics that assumes breaking things into parts is the only way to explain them.
• 🌱 She argues for the legitimacy of understanding living things through whole-part properties and complex systems, which offer scientific explanations beyond fundamental physics.
• 🚀 Allais introduces the concept of embodied agency, where self-organizing living systems have the capacity to move themselves towards goals, influencing even the behavior of fundamental particles and molecules.
