A savage can travel after a fashion in a jungle. Civilized activity is too complex to be carried on without smoothed roads. It requires signals and junction points; traffic authorities and means of easy and rapid transportation. It demands a congenial, antecedently prepared environment. Without it, civilization would relapse into barbarism in spite of the best of subjective intention and internal good disposition. The eternal dignity of labor and art lies in their effecting that permanent reshaping of environment which is the substantial foundation of future security and progress. Individuals flourish and wither away like the grass of the fields. But the fruits of their work endure and make possible the development of further activities having fuller significance. It is of grace not of ourselves that we lead civilized lives. There is sound sense in the old pagan notion that gratitude is the root of all virtue. Loyalty to whatever in the established environment makes a life of excellence possible is the beginning of all progress. The best we can accomplish for posterity is to transmit unimpaired and with some increment of meaning the environment that makes it possible to maintain the habits of decent and refined life. Our individual habits are links in forming the endless chain of humanity. Their significance depends upon the environment inherited from our forerunners, and it is enhanced as we foresee the fruits of our labors in the world in which our successors live. For however much has been done, there always remains more to do. We can retain and transmit our own heritage only by constant remaking of our own environment. Piety to the past is not for its own sake nor for the sake of the past, but for the sake of a present so secure and enriched that it will create a yet better future. Individuals with their exhortations, their preachings and scoldings, their inner aspirations and sentiments have disappeared, but their habits endure, because these habits incorporate objective conditions in themselves. So will it be with _our_ activities. We may desire abolition of war, industrial justice, greater equality of opportunity for all. But no amount of preaching good will or the golden rule or cultivation of sentiments of love and equity will accomplish the results. There must be change in objective arrangements and institutions. We must work on the environment not merely on the hearts of men. To think otherwise is to suppose that flowers can be raised in a desert or motor cars run in a jungle. Both things can happen and without a miracle. But only by first changing the jungle and desert.
