There is probably one purpose, and only one, for which the use of force by a government is beneficent, and that is to diminish the total amount of force used m the world. It is clear, for example, that the legal prohibition of murder diminishes the total amount of violence in the world. And no one would maintain that parents should have unlimited freedom to ill-treat their children. So long as some men wish to do violence to others, there cannot be complete liberty, for either the wish to do violence must be restrained, or the victims must be left to suffer. For this reason, although individuals and societies should have the utmost freedom as regards their own affairs, they ought not to have complete freedom as regards their dealings with others. To give freedom to the strong to oppress the weak is not the way to secure the greatest possible amount of freedom in the world. This is the basis of the socialist revolt against the kind of freedom which used to be advocated by _laissez-faire_ economists. Democracy is a device--the best so far invented--for diminishing as much as possible the interference of governments with liberty. If a nation is divided into two sections which cannot both have their way, democracy theoretically insures that the majority shall have their way. But democracy is not at all an adequate device unless it is accompanied by a very great amount of devolution. Love of uniformity, or the mere pleasure of interfering, or dislike of differing tastes and temperaments, may often lead a majority to control a minority in matters which do not really concern the majority. We should none of us like to have the internal affairs of Great Britain settled by a parliament of the world, if ever such a body came into existence. Nevertheless, there are matters which such a body could settle much better than any existing instrument of government. The theory of the legitimate use of force in human affairs, where a government exists, seems clear. Force should only be used against those who attempt to use force against others, or against those who will not respect the law in cases where a common decision is necessary and a minority are opposed to the action of the majority. These seem legitimate occasions for the use of force; and they should be legitimate occasions in international affairs, if an international government existed. The problem of the legitimate occasions for the use of force in the absence of a government is a different one, with which we are not at present concerned.
