Let us first observe that, as Mill pointed out long ago, there are many forms of collective action which do not involve coercion. The State may provide for certain objects which it deems good without compelling anyone to make use of them. Thus it may maintain hospitals, though anyone who can pay for them remains free to employ his own doctors and nurses. It may and does maintain a great educational system, while leaving everyone free to maintain or to attend a private school. It maintains parks and picture galleries without driving anyone into them. There is a municipal tramway service, which does not prevent private people from running motor buses along the same streets, and so on. It is true that for the support of these objects rates and taxes are compulsorily levied, but this form of compulsion raises a set of questions of which we shall have to speak in another connection, and does not concern us here. For the moment we have to deal only with those actions of State which compel all citizens, or all whom they concern, to fall in with them and allow of no divergence. This kind of coercion tends to increase. Is its extension necessarily an encroachment upon liberty, or are the elements of value secured by collective control distinct from the elements of value secured by individual choice, so that within due limits each may develop side by side?
We have already declined to solve the problem by applying Mill’s distinction between self-regarding and other-regarding actions, first because there are no actions which may not directly or indirectly affect others, secondly because even if there were they would not cease to be matter of concern to others. The common good includes the good of every member of the community, and the injury which a man inflicts upon himself is matter of common concern, even apart from any ulterior effect upon others. If we refrain from coercing a man for his own good, it is not because his good is indifferent to us, but because it cannot be furthered by coercion. The difficulty is founded on the nature of the good itself, which on its personal side depends on the spontaneous flow of feeling checked and guided not by external restraint but by rational self-control. To try to form character by coercion is to destroy it in the making. Personality is not built up from without but grows from within, and the function of the outer order is not to create it, but to provide for it the most suitable conditions of growth. Thus, to the common question whether it is possible to make men good by Act of Parliament, the reply is that it is not possible to compel morality because morality is the act or character of a free agent, but that it is possible to create the conditions under which morality can develop, and among these not the least important is freedom from compulsion by others.
The argument suggests that compulsion is limited not by indifference—how could the character of its members be matter of indifference to the community?—but by its own incapacity to achieve its ends. The spirit cannot be forced. Nor, conversely, can it prevail by force. It may require social expression. It may build up an association, a church for example, to carry out the common objects and maintain the common life of all who are like-minded. But the association must be free, because spiritually everything depends not on what is done but on the will with which it is done. The limit to the value of coercion thus lies not in the restriction of social purpose, but in the conditions of personal life. No force can compel growth. Whatever elements of social value depend on the accord of feeling, on comprehension of meaning, on the assent of will, must come through liberty. Here is the sphere and function of liberty in the social harmony.
Where, then, is the sphere of compulsion, and what is its value? The reply is that compulsion is of value where outward conformity is of value, and this may be in any case where the nonconformity of one wrecks the purpose of others. We have already remarked that liberty itself only rests upon restraint. Thus a religious body is not, properly speaking, free to march in procession through the streets unless people of a different religion are restrained from pelting the procession
