Our evils are due mainly to the failure to apply to our international relationships knowledge which is of practically universal possession, often sel… - Norman Angell

We use power, of course, in the international fields in a way which is the exact contrary to the way in which we use it within the state. In the international field, force is the instrument of the rival litigants, each attempting to impose his judgment upon the other. Within the state, force is the instrument of the community, the law, primarily used to prevent either of the litigants imposing by force his view upon the other. The normal purpose of police — to prevent the litigant taking the law into his own hands, being his own judge — is the precise contrary of the normal purpose in the past of armies and navies, which has been to enable the litigant to be his own judge of his own rights when in conflict about them with another.

One speaks of dictators ruling by "force". But what has enabled dictatorial governments to possess force? The only means by which a man can become a dictator is by getting at the public mind. The politician does not become dictator by the strength of his own muscles. He must persuade others, millions of others, to use their muscles in a certain way. The German National Socialists began as a party of ten persons. And it would have remained a party of ten persons had not its promoters been able to persuade — not force — others. Ten persons had no force as against the power of the German nation. The potential power of that party of ten persons consisted simply in its potential power to reach the public mind. Without that popular appeal it could never have come into being. And if, and when, it loses that popular appeal, it will cease to be.

I would not hesitate to say that nine out of ten of the critics of the peace movement get the argument turned upside down. "You cannot change human nature" has become a sort of incantation with those critics. Perhaps you cannot "change human nature" — I don't indeed know what the phrase means. But you can certainly change human behavior, which is what matters, as the whole panorama of history shows.
