„It may be necessary for the education of the real philosopher that he himself should have once stood upon all those steps […] he himself must perhaps have been critic, and dogmatist, and historian, and besides, poet, and collector, and traveler, and riddle-reader, and moralist, and seer, and „free spirit,“ and almost everything, in order to traverse the whole range of human values and estimations, and that he may be able with a variety of eyes and consciences to look from a height to any distance, from a depth up to any height, from a nook into any expanse. But all these are only preliminary conditions for his task; this task itself demands something else — it requires him to create values.“ 

– Friedrich Nietzsche, „Beyond Good and Evil“
