[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 NietzscheThe man who meets with a failure attributes this failure rather to the ill will of another than to fate.
