These small things - nutrition, place, climate, recreation, the whole casuistry of selfishness - are inconceivably more important than everything one has taken to be important so far.
Friedrich Nietzsche[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 Nietzsche
