Another measure which would do much to increase liberty would be an increase of self-government for subordinate groups, whether geographical or economic or defined by some common belief, like religious sects. A modern state is so vast and its machinery is so little understood that even when a man has a vote he does not feel himself any effective part of the force which determines its policy. Except in matters where he can act in conjunction with an exceptionally powerful group, he feels himself almost impotent, and the government remains a remote impersonal circumstance, which must be simply endured, like the weather. By a share in the control of smaller bodies, a man might regain some of that sense of personal opportunity and responsibility which belonged to the citizen of a city-state in ancient Greece or medieval Italy. When any group of men has a strong corporate consciousness--such as belongs, for example, to a nation or a trade or a religious body--liberty demands that it should be free to decide for itself all matters which are of great importance to the outside world. This is the basis of the universal claim for national independence. But nations are by no means the only groups which ought to have self-government for their internal concerns. And nations, like other groups, ought not to have complete liberty of action in matters which are of equal concern to foreign nations. Liberty demands self-government, but not the right to interfere with others. The greatest degree of liberty is not secured by anarchy. The reconciliation of liberty with government is a difficult problem, but it is one which any political theory must face. The essence of government is the use of force in accordance with law to secure certain ends which the holders of power consider desirable. The coercion of an individual or a group by force is always in itself more or less harmful. But if there were no government, the result would not be an absence of force in men's relations to each other; it would merely be the exercise of force by those who had strong predatory instincts, necessitating either slavery or a perpetual readiness to repel force with force on the part of those whose instincts were less violent. This is the state of affairs at present in international relations, owing to the fact that no international government exists. The results of anarchy between states should suffice to persuade us that anarchism has no solution to offer for the evils of the world.
