The internal orderliness of a civilized community is a great achievement, chiefly brought about by the increased authority of the State. It would be inconvenient if peaceable citizens were constantly in imminent risk of being robbed and murdered. Civilized life would become almost impossible if adventurous people could organize private armies for purposes of plunder. These conditions existed in the Middle Ages, and have not passed away without a great struggle. It is thought by many—especially by the rich, who derive the greatest advantage from law and order—that any diminution in the power of the State might bring back a condition of universal anarchy. They regard strikes as portents of dissolution. They are terrified by such organizations as the Confédération Générale du Travail and the International Workers of the World. They remember the French Revolution, and feel a not unnatural desire to keep their heads on their shoulders. They dread particularly any political theory which seems to excuse private crimes, such as sabotage and political assassination. Against these dangers they see no protection except the maintenance of the authority of the State, and the belief that all resistance to the State is wicked. Fear of the danger within is enhanced by fear of the danger without. Every State is exposed at all times to the risk of foreign invasion. No means has hitherto been devised for minimizing this risk except the increase of armaments. But the armaments which are nominally intended to repel invasion may also be used to invade. And so the means adopted to diminish the external fear have the effect of increasing it, and of enormously enhancing the destructiveness of war when it does break out. In this way a reign of terror becomes universal, and the State acquires everywhere something of the character of the Comité du Salut Public. The tribal feeling out of which the State develops is natural, and the fear by which the State is strengthened is reasonable under present circumstances. And in addition to these two, there is a third source of strength in a national State, namely patriotism in its religious aspect.
