The more abstract the truth you wish to teach, the more you must allure the senses to it

Truth is a mobile army of metaphors, metonyms, anthropomorphisms, in short a sum of human relations which have been subjected to poetic and rhetorical intensification, translation and decoration […]; truths are illusions of which we have forgotten that they are illusions, metaphors which have become worn by frequent use and have lost all sensuous vigour […].
