Roger Gilbertson has been there, done that. Since 1955 he has been auditioning and experimenting with specialties. Aiming at becoming a generalist in our complex culture. He describes why his background suits him for speculations on human history. Then he compares Primalization with Civilization. There are many differences. Our genes want to take us in one direction. Our personal micro-culture wants to direct us along a path of its own. We are all stressed. Nature and nurture are interlocked, negotiating and compromising within us for decisions and outcomes across a lifetime.
