"I cannot pretend that what I have done in regard to social and political problems has had any great importance. It is comparatively easy to have an immense effect by means of a dogmatic and precise gospel, such as that of Communism. But for my part I cannot believe that what mankind needs is anything either precise or dogmatic. Nor can I believe with any wholeheartedness in any partial doctrine which deals only with some part or aspect of human life. There are those who hold that everything depends upon institutions, and that good institutions will inevitably bring the millennium. And, on the other hand, there are those who believe that what is needed is a change of heart, and that, in comparison, institutions are of little account. I cannot accept either view. Institutions mould character, and character transforms institutions. Reforms in both must march hand in hand. And if individuals are to retain that measure of initiative and flexibility which they ought to have, they must not be all forced into one rigid mould; or, to change the metaphor, all drilled into one army. Diversity is essential in spite of the fact that it precludes universal acceptance of a single gospel. But to preach such a doctrine is difficult especially in arduous times. And perhaps it cannot be effective until some bitter lessons have been learned by tragic experience."
