'What vitiates nearly all that is written about antisemitism is the assumption in the writer's mind that he himself is immune to it. 'Since I know that antisemitism is irrational,' he argues, 'it follows that I do not share it.' He thus fails to start his investigation in the one place where he could get hold of some reliable evidence - that is, in his own mind.'
George Orwell, 'Antisemitism in Britain' in Essays, p.286.
