We believe that Lincoln would have wished his people to show a like partizanship to-day in the cause of right. Before we all steer quite out of the tested channel, let us at least remind you that those captains knew the course. It is idle to talk of a return to the past. The statesmanship of Franklin is not the statesmanship of to-day. What Lincoln felt is out of tune with the new America. We must go on with the vast new turmoils, the strange unguessed tendencies. We must find a fresh hope in the altered world. Meanwhile, be neutral, but do not bid us be neutral. You cannot silence us. We mean that our ideas shall live and fight and finally prevail. In one section of this book I deal with what the war is teaching us. The peoples of Europe are reasserting the rights of nationality. We must understand this. We need a wholesome sense of our own national being in the America of to-day. Nationality is the one great idea in the modern world, the one allegiance left us. It has absorbed the loyalties and fervor that used to be poured out upon art and religion. Groups of persons find emotional release in the Woman's Movement, in Trades Unions, in Socialism. But the one universal expression for the entire community is in nationalism, the assertion of selfhood as a people. Religious revivals no longer draw the mind of the mass people. But the idea of nationality sweeps them. It gives them the sense of kinship, it answers the desire for something to which to tie. It is easily possible that this idea will fade as the God of the Churches and the creative love of beauty faded. The Mazzini and Lincoln type of man may pass as the poet and the saint, Knights and Samurai, passed. But not in our time, not in a few hundred years to come. Nationalism may be only one more of the necessary "useful lies," one more illusion of the human race. But it will serve out our days. The mistake is in thinking that the heart of the common people will ever be satisfied with a bare mechanic civilization. Men are unwilling to live unless they have something to die for. We have filled the foreground in recent years with new automatic machines, new subdivisions of repetitive process. We tried to empty the huge modern world of its old values. Then the people came and smashed the structure, and found a vast emotional release in the war. The hope of a sane future is not in suppressing that dynamic of nationality. We must direct it.
