William of Ockham

Bill of Ockham was a 14th century Franciscan monk, a genius that had to hide from the Catholic Church for most of his life because of his beliefs, fueled by his faith in reason, and his reasoning about faith, which never met with approval by the institution. His core belief was that the simplest answer was usually the best answer in the solution of complicated problems. There is a difference between simple and simplistic. Simple as defined by the philosophy of Ockham  was arrived at after all conflicting data was ruled out and  the existing logic plucked of such detritus was named ontological parsimony. He recognized that "bull shit baffles brains." He may have thought of the prairie axiom, "Don't eat that Elmer, that's horse shit."  Simplistic is typified by Donald J Trump and is displayed by reductionist logic that descends to the lowest common denominator by ignoring conflicting data. Despite the fact that he is a grumpy fucker he is in contrast celebrated by the establishment. Bill of Ockham on the other hand was like Rodney Dangerfield , he got no respect in his day.
