TY - JOUR N2 - Krzysztof Maurin was an extremely versatile intellectual and academic teacher. He worked in mathematics (monograph “Methods of Hilbert space”), philosophy (publication “Karl Jaspers – a philosopher of truthfulness”), theology (essay “The Son of Man as the foundation of great religions”) as well as in psychology and he taught in the Faculty of Physics of the Warsaw University: I was taught by Him during a second half of His life since the beginning of the 70s. Now we are seeing and presenting his various activities in the time analysed by him in senses of quantum and cosmic physics, Heidegger's philosophy, Schweitzer's theology and human and humanitarian psychology. Therefore we remind below his lectures on Medieval Universities, Humboldt's reform, the XIX century mathematics and indeterministic interpretation of quantum mechanics. Then, according to a chronological order, we are switching our attention to Krzysztof Maurin himself as a student of university underground courses during the time do Nazists occupation in Poland, then as a silent university employee resisting communist totalitarian ideology and after 1956, as a methodical professor of the University of Warsaw collaborating with Western Europe scientists such as LDrs GDrding, Werner Heisenberg, Rene Thom and Friedrich von Weizsacker as well as admiring especially intellectual achievements of Hermann Weyl and Martin Heidegger. To the end of biographical considerations we can observe successes and obstacles encountered by Krzysztof Maurin while He has tended to conciliate various or opposite ways of philosophical understanding or social behaving by his beloved thinkers.
