The Need for Classification
Man designs for himself a garden with a hundred kinds of trees, a thousand kinds of flowers, a hundred kinds of fruit and vegetables. Suppose, then, that the gardener of this garden knew no other distinction between edible and inedible, nine-tenths of this garden would be useless to him. He would pull up the most enchanting flowers and hew down the noblest trees and even regard them with a loathing and envious eye. This is what the Steppenwolf does with the thousand flowers of his soul. What does not stand classified as either man or wolf he does not see at all.
Hermann Hesse, in 'Steppenwolf'
