Are human beings Ockham machines?

Humans are Parsimony Machines (Ockham Machines): they select the shortest (and, thereby, most efficient) path to the production of true theorems, given a set of facts (observations) and a set of theories. Another way to describe the activity of Ockham Machines: they produce the maximal number of true theorems in any given period of time, given a set of facts and a set of theories.

(William of Ockham was, after all a Franciscan monk and constantly in search for a Prima Causa)
