I fly in dreams, I know it is my privilege, I do not recall a single situation in dreams when I was unable to fly. To execute every sort of curve and angle with a light impulse, a flying mathematics - that is so distinct a happiness that it has permanently suffused my basic sense of happiness.
Friedrich NietzscheOne thing a man must have: either a naturally light disposition or a disposition lightened by art and knowledge.
Friedrich NietzscheA refined nature is vexed by knowing that some one owes it thanks, a coarse nature by knowing that it owes thanks to some one.
Friedrich Nietzsche
