Dr. Edelman passed away yesterday. He won the Nobel prize back in 1972 with Robert Porter for their work on the immune system. In his later career he focused on neuroscience and philosophy. I read his book, A Universe of Consciousness: How matter becomes imagination, co-authored with Giulio Tononi last year. A great read. His approach to the the matters of brain and mind were quite scholarly and advanced. He did a lot of research using neural net models to simulate the brain, which usually I find fault with, but not his use of them because he was so grounded theoretically and philosophically. And a good writer to boot. So thank you, Dr. Edelman, for helping us understand our biological roots better.
