George Orwell

The most one can say is that people can be fairly good prophets when their wishes are realizable. But a truly objective approach is almost impossible, because in one form or another almost everyone is a nationalist... The most intelligent people seem capable of holding schizophrenic beliefs, or disregarding plain facts, of evading serious questions with debating-society repartees, or swallowing baseless rumours and of looking on indifferently while history is falsified.
