Paper: “Closure to efficient causation, computability and artificial life”

I missed the publication of this last month. The abstract [1]: The major insight in Robert Rosen’s view of a living organism as an (M,R)-system was the realization that an organism must be “closed to efficient causation”, which means that the catalysts needed for its operation must be generated internally. … Continue reading

The paper makes a lengthy series of erroneous arguments based on misinterpretations of Rosen’s arguments. Wells begins with a list of statements drawn from Rosen’s … Continue reading

Remarks on Chu-Ho Fall 2007

MIT Artificial Life summer issue – Chu-Ho revisited

The summer 2007 issue of Artificial Life is now available. As I previously mentioned, this issue contains three papers relevant to Rosen. They all revolve around the 2006 paper by Chu and Ho: “A Living System Must Have Noncomputable Models” by A.H. Louie Abstract: “Chu and Ho’s recent article in … Continue reading
