in maintaining that the existence of such an economic system as they desire would prevent the commission of crimes of this kind, the laws forbidding them would no longer come into operation, and would do no harm to liberty. If, on the other hand, the impulse to such actions persisted, it would be necessary that steps should be taken to restrain men from indulging it.
3. The third class of difficulties is much the most serious, and involves much the most drastic interference with liberty. I do not see how a private army could be tolerated within an Anarchist community, and I do not see how it could be prevented except by a general prohibition of carrying arms. If there were no such prohibition, rival parties would organize rival forces, and civil war would result. Yet, if there is such a prohibition, it cannot well be carried out without a very considerable interference with individual liberty. No doubt, after a time, the idea of using violence to achieve a political object might die down, as the practice of duelling has done. But such changes of habit and outlook are facilitated by legal prohibition, and would hardly come about without it. I shall not speak yet of the international aspect of this same problem, for I propose to deal with that in the next chapter, but it is clear that the same considerations apply with even greater force to the relations between nations.
If we admit, however reluctantly, that a criminal law is necessary and that the force of the community must be brought to bear to prevent certain kinds of actions, a further question arises: How is crime to be
