Nicholas of Cusa rejected Aristotelianism dominant in theology and philosophy at the end of the middle ages and adopted neo-Platonist ideas and even went back to the philosophy of , a pre-Socratic philosopher.

The idea of God has many aspects which appear to be contradictory. It is similar to a human face which may present different appearances when perceived from different perspectives.

During that period von Bertalanffy as a young scholar was not only interested in biology and philosophy of science. He was also interested in history and generally in humanities. He studied Oswald Spengler's theory of history and has written a paper on this topic. His interest in Spengler's theory of history anticipated von Bertalanffy's lifelong attempts to reconcile sciences with humanities.

The same division may be applied to scholars and philosophers, namely into those who create new paradigms and into those who work within the established ones.
