Famous philosopher Bertrand Russell joins Dr. Al Scott to explore determinism, free will, and their connections to physics, neuroscience, and AI. They discuss the illusion of free will, the mechanistic nature of the universe, and the implications for consciousness and decision-making. They also delve into quantum mechanics and its role in the debate on moral responsibility. Join the conversation and support the podcast!
Quantum mechanics challenges the notion of determinism by introducing randomness and uncertainty in the universe.
Neuroscience experiments suggest that free will may be an illusion, as physical processes predict decisions before conscious awareness.
Deep dives
Determinism in the Universe
Physics shows that the universe is largely mechanistic and appeared deterministic until the discovery of quantum mechanics. Quantum mechanics introduced randomness and uncertainty, challenging the notion of determinism. While quantum events may introduce randomness, most macroscopic processes are still mechanistically determined, except those influenced by quantum collapse. This creates discomfort as it challenges the idea of free will and a separate consciousness controlling our actions.
Emergence of Consciousness
The concept of emergence suggests that consciousness is an emergent property emerging from complex mechanistic interactions within our bodies. The intricate network of cells and neural networks in our brain, along with memories and experiences, contribute to the emergence of consciousness. Neuroscience experiments have shown that physical processes predicting decisions can be measured before subjects are consciously aware of making those decisions, implying that free will may be an illusion.
Quantum Mechanics and Free Will
Quantum mechanics, with its random quantum collapses, has been suggested as a potential source of free will. However, the randomness in quantum mechanics does not provide a lever for a separate consciousness to influence outcomes. The randomness may be influenced by prior causes, but it does not align with the idea of a spiritual avatar controlling decisions. The debate around free will and determinism raises questions about personal responsibility and the need for moral and ethical standards.
Thank you for inviting me into your head. In this episode I want to go deep and share some thoughts on brains and machines and free will. My thoughts on determinism and free resonate with the words of famous philosopher Bertrand Russell. My thinking on these topics is influenced by the evidence of physics, neuroscience, and AI. I hope you enjoy this exploration of some mind bending ideas.
