Thus no one of course undertakes to deny the obvious fact that in order to have a society a certain amount of similarity must exist. In one sense society rests on likeness: the likeness between men is deeper than their difference. We could not have an enemy unless there was much in common between us. With my friend all the aims that we share unite us. In a given society the members have the same interests, the same ends, in the main, and seek a common fulfilment. Differences are always grounded in an underlying similarity. But all this kind of “similarity” isn’t worth mentioning because we _have_ it. The very fact that it is common to us all condemns it from the point of view of progress. Progress does not depend upon the similarity which we _find_ but upon the similarity which we _achieve_. The new psychology, therefore, gives us individual responsibility as the central fact of life because it demands that we grow our own like-mindedness. To-day we are basing all our hopes not on the given likeness but the created unity. To rest in the given likeness would be to annihilate social progress. The organization of industry and the settlement of international relations must come under the domination of this law. The Allies are fighting to-day with one impulse, one desire, one aim, but at the peace table many differences will arise between them. The progress of the whole world at that moment will depend upon the “similarity” we can create. This “similarity” will consist of all we now hold in common and also, of the utmost importance for the continuance of civilization, upon our ability to unify our differences. If we go to that peace table with the idea that the new world is to be based on that community of interest and aim which now animates us, the disillusion will be great, the result an overwhelming failure. Let us henceforth, therefore, use the word unifying instead of similarity to represent the basis of association. And let us clearly understand that unifying is a process involving the continuous activity of every man. To await “variation-giving” individuals would be to make life a mere chance. We cannot wait for new ideas to appear among us, we must ourselves produce them. This makes possible the endless creation of new social values. The old like-minded theory is too fortuitous, too passive and too negative to attract us; creating is the divine adventure. Let us imagine a group of people whom we know. If we find the life of that group consisting chiefly of imitation, we see that it involves no activity of the real self but crushes and smothers it. Imitation condemns the human race. Even if up to the present moment imitation has been a large factor in man’s development, from this moment on such a smothering of all the forces of life must cease.
