Tribal feeling, which always underlay loyalty to the sovereign, has remained as strong as it ever was, and is now the chief support for the power of the State. Almost every man finds it essential to his happiness to feel himself a member of a group, animated by common friendships and enmities and banded together for defense and attack. But such groups are of two kinds: there are those which are essentially enlargements of the family, and there are those which are based upon a conscious common purpose. Nations belong to the first kind, Churches to the second. At times when men are profoundly swayed by creeds national divisions tend to break down, as they did in the wars of religion after the Reformation. At such times a common creed is a stronger bond than a common nationality. To a much slighter extent, the same thing has occurred in the modern world with the rise of socialism. Men who disbelieve in private property, and feel the capitalist the real enemy, have a bond which transcends national divisions. It has not been found strong enough to resist the passions aroused by the present war, but it has made them less bitter among socialists than among others, and has kept alive the hope of a European community to be reconstructed when the war is over. In the main, however, the universal disbelief in creeds has left tribal feeling triumphant, and has made nationalism stronger than at any previous period of the world’s history. A few sincere Christians, a few sincere socialists, have found in their creed a force capable of resisting the assaults of national passion, but they have been too few to influence the course of events or even to cause serious anxiety to the Governments. It is chiefly tribal feeling that generates the unity of a national State, but it is not only tribal feeling that generates its strength. Its strength results principally from two fears, neither of which is unreasonable: the fear of crime and anarchy within, and the fear of aggression from without.
