The Giants Shoulder #66 Meet the Scientist Exploring Consciousness Through Thermodynamics!
16 snips
Oct 16, 2025 Terrence Deacon, a neuro-anthropologist and author, explores the intricate relationship between thermodynamics, evolution, and consciousness. He discusses how the brain isn't just a computer, and why meaning emerges from information. Deacon dives into the origins of life, considering alternative chemistry and the evolution of genetic codes. He tackles concepts like normativity and agency, explaining how language shapes human experience. Finally, he challenges the notion of sentient AI, emphasizing the dynamic nature of life and consciousness.

Episode notes
Self-Organization Alone Can't Explain Life
- Self-organizing thermodynamic processes can create order but they tend to destroy the gradients that produce them.
- Therefore self-organization alone cannot fully explain life, which must maintain itself against those destructions.
Convergent Constraints Shaped Brains
- Nervous systems likely evolved multiple times and converge on similar solutions due to shared functional constraints.
- Ion-based signaling (sodium, potassium, calcium) and fast polarization are likely universal solutions for rapid information transfer.
LUCA Locked In A Single Genetic Language
- LUCA represents a bottleneck where one genetic code outcompeted diverse earlier chemistries.
- That early fixation explains why DNA/RNA appear universal despite prior biochemical diversity.
