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.
