“… Although initially skeptical, I found his whole system quite fascinating and thought provoking… I thought that his model was superior to those already available. His proposed books will be important advances in thinking on the origin and evolution of life and society… His presentation was made with the care and rigor of a serious and dedicated scholar. He has a good and up to date understanding of the natural sciences. I could not detect a trace of mysticism or journalistic pseudo-science in his presentation. Mr. Marr is a hard-headed thinker in the best scientific tradition. He deserves serious attention.”
