The drive toward the formation of metaphors is the fundamental human drive, which one cannot for a single instant dispense with in thought, for one would thereby dispense with man himself.
Friedrich Nietzsche, “On Truth and Lies in a Nonmoral Sense", 1873
Also Nietzsche: "“What do the people actually take knowledge to be? What do they want when they want ‘knowledge’? Nothing more than this: something unfamiliar is to be traced back to something familiar.”"
