“The key to understanding the course of history is to divide history into two parts. One part follows a predetermined direction and the other part is random and unpredictable. The part that follows a predetermined direction is the part that results from ever increasing human knowledge of the world we live in. The world we live in is structured and understandable and is explained by the laws of physics, chemistry and biology and the known properties of the particles, elements and compounds that make up our world. Our ever increasing knowledge of these laws and properties of matter comes to us in a predetermined and rational order from the easiest discoveries being made first to the more difficult discoveries being made later.”
