Bayesianism has its uses, but it is not the final answer. It is itself the product of a more fundamental process: evolution. Science, technology, language, and culture are all governed by evolution. I believe that this gives much deeper insight into science and knowledge than Bayesianism. See:

(1) Multiple Discovery: The Pattern of Scientific Progress, Lamb and Easton (2) Without Miracles: Universal Selection Theory and the Second Darwinian Revolution, Cziko (3) Darwin's Dangerous Idea: Evolution and the Meanings of Life, Dennett (4) The Evolution of Technology, Basalla

Scientific method itself evolves. Bayesianism is part of that evolution, but only a small part.
