Dear Guy, Please allow me to respond to your invitation to Terry with my two cents. My triad for supporting the dynamics of life is a bit different. I see the three essential fundamentals as: 1. Aleatoricism 2. Feedback 3. Memory Just to briefly elaborate on each: 1. I use aleatoricism to

Josephson and Deutsh are not ‘deeper than QM’. Deutsch for example is a very literal interpretation of QM that says that all the trajectories in the Feynman path sum are real, and they occur in parallel universes. This is a nice mathematical way to think, but it is not deeper than present QM!

I personally consider metabolism to be at the core of what constitutes ‘life’, so the notion of autopoeisis is very attractive to me. It is also possible that the richness of life as we know it depends on having metabolisms (activity), genomes (memory), and reproduction combined. The

Thank you for your responses, Lou and Stan. I am aware about the details of the autopoietic model. What I was actually addressing by the transition from abiotic to biotic structures and the later emergence of RNA and DNA was this elusive aspect of “mass action” which Stan mentioned, that in my

This is a reply to Plamen’s comment about autopoeisis. In their paper Maturana,Uribe and Varela give a working model (computer model) for autopoeisis. It is very simple, consisting of a subtrate of nodal elements that tend to bond when in proximity, and a collection of catalytic nodal elements

Dear Lou, Pedro and All, I am going to present a few opportunistic ideas related to what was said before in this session. Coming back to Pivar’s speculative mechano-topological model of life excluding genetics I wish to turn your attention to another author with a similar idea but on a sound
