I know that you have come here today to hear explanations. Well, don't expect to hear any explanations about Dada. You explain to me why you exist. You haven't the faintest idea. You will say: I exist to make my children happy. But in your hearts you know that isn't so. You will say: I exist to guard my country, against barbarian invasions. That's a fine reason. You will say: I exist because God wills. That's a fairy tale for children.

'Lecture on Dada', 1922
