To use the same words is not a sufficient guarantee of understanding; one must use the same words for the same genus of inward experience; ultimately one must have one's experiences in common.
Friedrich NietzscheActual philosophers... are commanders and law-givers: they say "thus it shall be!", it is they who determine the Wherefore and Whither of mankind, and they possess for this task the preliminary work of all the philosophical laborers, of all those who have subdued the past - they reach for the future with creative hand, and everything that is or has been becomes for them a means, an instrument, a hammer.
Friedrich Nietzsche
