Context: Consider MacArthur and his Republican supporters. So limited is his intelligence and his imagination that he is never puzzled for one moment. All we have to do is to go back to the days of the Opium War. After we have killed a sufficient number of millions of Chinese, the survivors among them will perceive our moral superiority and hail MacArthur as a saviour. But let us not be one-sided. Stalin, I should say, is equally simple- minded and equally out of date. He, too, believes that if his armies could occupy Britain and reduce us all to the economic level of Soviet peasants and the political level of convicts, we should hail him as a great deliverer and bless the day when we were freed from the shackles of democracy. One of the painful things about our time is that those who feel certainty are stupid, and those with any imagination and understanding are filled with doubt and indecision.
