Shifting Focus: Cognition Over Life in Biological Emergence

Understand why defining "life" hinders discovery and how framing systems by their cognitive capacity unlocks new insights into chemistry, biology, and nature itself.

Short Summary

  • Binary classifications like "life" trap science in unsolvable paradoxes and block the transfer of analytical tools across disciplines.
  • Michael Levin advocates prioritizing the spectrum of cognition, which he argues emerges well before complex cellular structures.
  • Novel experimental work demonstrates that basic learning mechanisms (habituation, conditioning) exist in non-living molecular networks, indicating free cognitive potential in physics.
  • This approach suggests reality is continuously reenchanted upon closer scientific inspection, provided we use the correct analytical detectors.
  • This discussion reorients how we approach complex biological systems, viewing them as integrated, high-agency wholes rather than just collections of parts.

This discussion with synthetic biologist Michael Levin explores his provocative view that the quest defining life is secondary to understanding cognition. Levin details research showing chemical networks exhibit memory and learning, powered by a mathematical ratchet that favors increasing causal emergence, offering a unified framework that bypasses reductionist limitations.

Description

Michael Levin is a synthetic biologist at Tufts University who believes that asking questions about “life” is a fruitless project. Instead, he argues that we ought to be trying to understand the emergence of cognition - a feature that he believes appears long before cells emerge. As part of this project, Levin has started to pull on a series of threads woven through the origin of life debate that seem to show basic elements of thinking systems - habituation, sensitization, conditioning - can be found in simple physical networks. We dig into how these systems work, what they reveal about life, and how his approach to understanding nature resolves a lot of biological paradoxes.

Loved this episode! In the future, would it be okay if you guys did a little 5-10 minute segment, after you guys are done talking with the guest, where you both digest what was discussed and summarize your final thoughts on the topic? Thank, appreciate and love you!

Levin is always exciting to listen to. I can appreciate why he doesn’t like to discuss whether things are living or non-living but is interested in cognition. Any judgement we make about these issues is based on phenomenology. There’s surely no substance called life so it’s just a judgement based on the complexity of the way something behaves as it appears to us. Not surprisingly, since there is a scale of complexity in behaviour, there will be edge cases that are hard to call but we consider the ability of something to react to its environment in a timely manner which promotes its own interest to indicate agency which, along with cognition, is the other factor we consider valuable to a system or organism.

Thanks for that shot of dopamine... Levin fanboy for life! Consider adding a response/recap at the end. Love your work! 🙏

Came here from James Nestor's reference to Dr Michael Levin on the Tim Ferriss Podcast. Amazing that this episode came out just yesterday, just when I wanted to find out more about him today... cool!

Michael Levin is not only brilliant, he also has a contagious awe and wonder about life. What a great attitude for a scientist! His research is so interesting, I guess you'd have to be a cyborg not to appreciate how wonderful life is. Thank you for bringing him on!

This reminds me of what Terrence Howard was saying about chemistry!

indeed, at 20:35, cognition is key, and allow me add to this, "the rate of cognition", this means time, changes in an insect can observed in a short time space, changes in a rock can also be observed, but in a very long time space
