In short, there are two schools of social reform. One bases itself upon the notion of a morality which springs from an inner freedom, something mysteriously cooped up within personality. It asserts that the only way to change institutions is for men to purify their own hearts, and that when this has been accomplished, change of institutions will follow of itself. The other school denies the existence of any such inner power, and in so doing conceives that it has denied all moral freedom. It says that men are made what they are by the forces of the environment, that human nature is purely malleable, and that till institutions are changed, nothing can be done. Clearly this leaves the outcome as hopeless as does an appeal to an inner rectitude and benevolence. For it provides no leverage for change of environment. It throws us back upon accident, usually disguised as a necessary law of history or evolution, and trusts to some violent change, symbolized by civil war, to usher in an abrupt millennium. There is an alternative to being penned in between these two theories. We can recognize that all conduct is _interaction_ between elements of human nature and the environment, natural and social. Then we shall see that progress proceeds in two ways, and that freedom is found in that kind of interaction which maintains an environment in which human desire and choice count for something. There are in truth forces in man as well as without him. While they are infinitely frail in comparison with exterior forces, yet they may have the support of a foreseeing and contriving intelligence. When we look at the problem as one of an adjustment to be intelligently attained, the issue shifts from within personality to an engineering issue, the establishment of arts of education and social guidance.
