Social progress is to be sure coadapting, but coadapting means always that the fresh unity becomes the pole of a fresh difference leading to again new unities which lead to broader and broader fields of activity. 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. 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.
The very fact that it is common to us all condemns it from the point of view of progress. This view of the social process gives us individual responsibility as to 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.
