People are not always more reasonable than governments . . . [and] public opinion, or what passes for public opinion, is not invariably a moderating force in the jungle of politics. It may be true, and I suspect it is, that the mass of people everywhere are normally peace-loving and would accept many restraints and sacrifices in preference to the monstrous calamities of war. But I also suspect that what purports to be public opinion in most countries that consider themselves to have popular government is often not really the consensus of the feelings of the mass of the people at all, but rather the expression of the interests of special highly vocal minorities — politicians, commentators, and publicity-seekers of all sorts: people who live by their ability to draw attention to themselves and die, like fish out of water, if they are compelled to remain silent. These people take refuge in the pat and chauvinistic slogans because they are incapable of understanding any others, because these slogans are safer from the standpoint of short-term gain, because the truth is sometimes a poor competitor in the market place of ideas — complicated, unsatisfying, full of dilemma, always vulnerable to misinterpretation and abuse. The counsels of impatience and hatred can always be supported by the crudest and cheapest symbols; for the counsels of moderation, the reasons are often intricate, rather than emotional, and difficult to explain. And so the chauvinists of all times and places go their appointed way: plucking the easy fruits, reaping the little triumphs of the day at the expense of someone else tomorrow, deluging in noise and filth anyone who gets in their way, dancing their reckless dance on the prospects for human progress, drawing the shadow of a great doubt over the validity of democratic institutions. And until people learn to spot the fanning of mass emotions and the sowing of bitterness, suspicion, and intolerance as crimes in themselves — as perhaps the greatest disservice that can be done to the cause of popular government — this sort of thing will continue to occur.
