The human tongue is a furnace in which the temper of our souls is daily tried. All words are pegs to hang ideas on. Language is the house of Being. He who does not understand words, cannot understand people. All words are spiritual.
Nothing is more spiritual than words.
Those things for which we find words, are things we have already overcome. I cannot love a friend whose love is words. The heart of a fool is in his mouth, but the mouth of a wise man is in his heart. A fool and his words are soon parted. Slang is a language that rolls up its sleeves, spits on its hands and goes to work.
