“There is no great discoveries and advances, as long as there is an unhappy child on earth. / Ne možemo govoriti o napretku čovječanstva, dok na svijetu ima nesretne djece.”

“Značajni problemi s kojima se suočavamo ne mogu biti riješeni na nivou razmišljanja koje je probleme kreiralo.”

“Concepts that have proven useful in ordering things easily achieve such authority over us that we forget their earthly origins and accept them as unalterable givens. Thus they come to be stamped as “necessities of thought”, “a priori givens”, etc. The path of scientific advance is often made impassable for a long time through such errors. For that reason, it is by no means an idle game if we become practiced in analyzing the long commonplace concepts and exhibiting those circumstances upon which their justification and usefulness depend, how they have grown up, individually, out of the givens of experience. By this means, their all-too-great authority will be broken. They will be removed if they cannot be properly legitimated, corrected if their correlation with given things be far too superfluous, replaced by others if a new system can be established that we prefer for whatever reason.”

“As long as there are sovereign nations possessing great power, war is inevitable.”

“I never made one of my discoveries through the process of rational thinking”

“It occurred to me by intuition, and music was the driving force behind that intuition. My discovery was the result of musical perception.”

“Do not grow old, no matter how long you live. Never cease to stand like curious children before the Great Mystery into which we were born.”
