The idea of adaptation to environment has been so closely connected with the “struggle for existence” theory that some people do not seem to realize that in giving up the latter, the former still has force, although with a somewhat different connotation. We now feel not only that adaptation to environment is compatible with coöperation, but that coöperation is the basis of adaptation to environment. But our true environment is psychic, and as science teaches adaptation to the physical, so group psychology will teach the secret of membership in the psychic environment, will teach the branch to know its vine, where its own inner sources of life are revealed to it. Then we shall understand that environment is not a hard and rigid something external to us, always working upon us, whose influence we cannot escape. Not only have self and environment acted and reacted upon each other, but the action and reaction go on every moment; both self and environment are always in the making. The individual who has been affected by his environment acts on an environment which has been affected by individuals. We shall need an understanding of this for all our constructive work: it is not that formative influences work on a dead mass of inertia, but formative influences work on an environment which has already responded to initiatives, and these initiatives have been affected by the responses. We cannot be practical politicians without fully understanding this. Progress then must be through the group process. Progress implies respect for the creative process not the created thing; the created thing is forever and forever being left behind us. The greatest blow to a hide-bound conservatism would be the understanding that life is creative at every moment. What the hard-shelled conservative always forgets is that what he really admires in the past is those very moments when men have strongly and rudely broken with tradition, burst bonds, and created something. True conservatism and true progressivism are not two opposites: conservatives dislike “change,” yet they as well as progressives want to grow; progressives dislike to “stand pat,” yet they as well as conservatives want to preserve what is good in the present. But conservatives often make the mistake of thinking they can go on living on their spiritual capital; progressives are often too prone not to fund their capital at all.
