"Once a thing is known it can never be unknown. It can only be forgotten. And, in a way that bends time, so long as it is remembered, it will indicate the future. It is wiser, in every circumstance, to forget, to cultivate the art of forgetting. To remember is to face the enemy. The truth lies in remembering."
© Anita Brookner 1983 (In the book: Look at Me.)
Think of this next time you hear a politician say: "I can't remember" or "I do not recall having said that".
