individual in conflict with the will of the community as a whole. When such conflict occurs, it would seem that we must be prepared for one of two things. Either we must admit the legitimacy of coercion, avowedly not in the interests of freedom but in furtherance, without regard to freedom, of other ends which the community deems good. Or we must admit limitations which may cramp the development of the general will, and perchance prove a serious obstacle to collective progress. Is there any means of avoiding this conflict? Must we leave the question to be fought out in each case by a balance of advantages and disadvantages, or are there any general considerations which help us to determine the true sphere of collective and of private action? 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 any one to make use of them. Thus it may maintain hospitals, though any one 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 every one free to maintain or to attend a private school. It maintains parks and picture galleries without driving any one 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?
