We uphold a general viewpoint that the ideas have their own ‘objective’ dynamics, that is a dynamics independent of personalities. Every now and then, the ideas are accessible to individuals. When it comes to social expression, though, it is only a genius, among individuals, who can reach such an accessible idea as ultimate truth, even to the point where he/she succeeds to casting it into proper words, available to society at large. Beyond those words no one can ‘rationalize’, not even the genius himself. We illustrate this observation with Erwin Schrödinger’s interpretation of the wave function introduced by him to common knowledge, which has been cast into proper words by another genius, Richard Feynman, who, nevertheless, honestly acknowledged mistrusting that interpretation. In fact, Feynman always openly admitted, and effectively exercised the probabilistic interpretation of Max Born. To wit, it is guided by this kind of interpretation, that he has built the well-known version of wave mechanics, which is based entirely on the concept of probability. We argue that Feynman was actually right on both accounts – Schrödinger’s and Born’s interpretations – and show here why and how, thus revealing a few missing points in the contemporary natural philosophy. The whole argument, and the accompanying illustration, stands completely by the words of still another genius of modern physics: Louis de Broglie, whose physics is documented and developed in the present work. The construction of this physics gives us the opportunity of a historical review of significant moments of the physical knowledge
