Bertrand Russell,
The Practice and Theory of Bolshevism…
(1920)
“ In politics, as in private life, men invent myths to rationalize their conduct. If a man thinks that the only reasonable motive in politics is economic self-advancement, he will persuade himself that the things he wishes to do will make him rich. When he wants to fight the Germans, he tells himself that their competition is ruining his trade. If, on the other hand, he is an "idealist," who holds that his politics should aim at the advancement of the human race, he will tell himself that the crimes of the Germans demand their humiliation. ”
