Max PlanckModern physics has taught us that the nature of any system cannot be discovered by dividing it into its component parts and studying each part by itself... We must keep our attention fixed on the whole and on the interconnection between the parts. The same is true of our intellectual life. It is impossible to make a clear cut between science, religion, and art. The whole is never equal simply to the sum of its various parts.
