[Heraclitus] did not require humans or their sort of knowledge, since everything into which one may inquire he despises [as being] in contrast [to his own] inward-turning wisdom. [To him] all learning from others is a sign of nonwisdom, because the wise man focuses his vision on his own intelligence.
Friedrich NietzscheWhat the sense feeleth, what the spirit discerneth, hath never its end in itself. But sense and spirit would fain persuade thee that they are the end of all things: so vain are they.
Friedrich NietzscheThis sign I give you: every people speaks its tongue of good and evil, which the neighbor does not understand. It has invented its own language of customs and rights.
Friedrich Nietzsche
