The new kings of the world will live tranquilly for a long time, confining themselves to devouring each other and being parasites among each other on a cottage industry scale.”
—Primo Levi (1919–1987)
“To try to write love is to confront the muck of language: that region of hysteria where language is both too much and too little, excessive ... and impoverished.”
