Moreover, we think now of the survival of groups rather than of individuals. For the survival of the group the stronger members must not crush the weaker but cherish them, because the spiritual and social strength which will come from the latter course makes a stronger group than the mere brute strength of a number of “strong” individuals. That is, the strength of the group does not depend on the greatest number of strong men, but on the strength of the bond between them, that is, on the amount of solidarity, on the best organization. But it might be said, “You still evidently believe in struggle, only you make the group instead of the individual the unit.” No, the progress of man must consist in extending the group, in belonging to many groups, in the relation of these groups. If we accept life as endless battle, then we shall always have the strong overcoming the weak, either strong individuals conquering the weak, or a strong group a weak group, or a strong nation a weak nation. But synthesis is the principle of life, the method of social progress. Men have developed not through struggle but through learning how to live together. Lately the struggle theory has been transferred from the physical to the intellectual world. Many writers who see society as a continuous conflict think its highest form is discussion. One of these says, “Not for a moment would I deny that fighting is better carried on by the pen than by the sword, but some sort of fighting will be necessary to the end of the world.” No, as long as we think of discussion as a struggle, as an opportunity for “argument,” there will be all the usual evil consequences of the struggle theory. But all this is superficial. If struggle is unavailing, it is unavailing all along the line. It is not intellectual struggle that marks the line of progress, but any signs of finding another method than struggle. Two neighbors quarrelling in words are little more developed than two men fighting a duel. We must learn to think of discussion not as a struggle but as experiment in coöperation. We must learn coöperative thinking, intellectual team-work. There is a secret here which is going to revolutionize the world. Perhaps the most profound reason against struggle is that it always erects a thing-in-itself. If I “fight” Mr. X, that means that I think of Mr. X as incapable of change—that either he or I must prevail, must conquer. When I realize fully that there are no things-in-themselves, struggle simply fades away; then I know that Mr. X and I are two flowing streams of activity which must meet for larger ends than either could pursue alone. Is Germany the last stronghold of the old theory of evolution, is she the last being in a modern world to assert herself as a thing-in-itself? President Wilson’s contribution to this war is that he refuses to look upon Germany as a thing-in-itself.
