“I remember a joke from my childhood that Stalin had read a letter from Trotsky that said, “You were right, and I was wrong. You are the true heir of Lenin, and I should apologize.” And a man ran up and said, “No, you forget that Trotsky was Jewish. The proper reading is: You were right, and I was wrong? You are the true heir of Lenin, and I should apologize?”—Steven Pinker http://www.theatlantic.com/entertainment/archive/2014/12/steven-pinker-interview/384092/
