This idea of nationalism, instead of being an early and now obsolete idea, is a recent and a noble idea. What the common life of the home is to the father and mother and children, through poverty and childbirth and fame, that is the life of a nation to its citizens. In the blood of sacrifice it is welded together. Mixed races cannot dilute it, a doctored border cannot suppress it, a stern climate cannot quench it, an oppressive government cannot enslave it. Only one thing can destroy it and that is when it annuls its past and weakens at the heart. When it ceases to respond to the great ideas that once aroused it, then it is time for those who love it to look to the influences at work that have made it forgetful. The denial of that common experience, the refusal to inherit the great tradition, the unwillingness to continue the noble and costly policy--these mark the decline of a nation. These are the signs of peril we see in the unwieldy life of our immense democracy to-day. The call that came to us from France was the same voice that we once knew as the voice of our most precious friend. By our failure to respond we show that we have allowed something alien to enter our inmost life. In our equal failure to safeguard our own helpless non-combatants, we reveal that the old compulsions no longer move us. By the cry that went up from half our nation--not of outrage at stricken France, not of anger for slaughtered children of our own race--but that strange mystical cry, "He kept us out of war," we betray that we have lost our hardihood. We have been overwhelmed by numbers. We have suffered such a heaping up of new elements that we have no time to teach our tradition, no will to continue our race experience. I was talking of this recently with a profound student of race psychology, Havelock Ellis. He said that the determining factor is the strength of the civilization receiving the fresh contributions. Is that civilization potent enough to shape the new contributions? The French have always had their boundaries beaten in upon by other races, but so distinctive, so salient, is their civilization that it absorbs the invasion. He said that the question to decide is whether the cells are sufficiently organized and determinate to receive alien matter. Surely no student of our social conditions can say that our tendencies are clear, our collective will formed, our national mind unified. We keep adding chemical elements without coming to a solution. England accepted a few invasions and conquests and then had to stiffen up and work the material into a mold. France was overrun every half century, but finally she drew the sacred circle around her borders, and proceeded to the work of coalescing her parts. Our present stream of tendency, and our present grip on our own historic tradition, are not strong enough to admit of immense new European contributions. We are losing the sense of what we mean as a people.
