The situation defines the vital office of present philosophy. It has to search out and disclose the obstructions; to criticize the habits of mind which stand in the way; to focus reflection upon needs congruous to life; to interpret the conclusions of science with respect to their consequences for our beliefs about purposes and values in all phases of life. The development of a system of thought capable of giving this service is a difficult undertaking; it can proceed only slowly and through coöperative effort. In these pages I have tried to indicate in outline the nature of the task to be accomplished and to suggest some of the resources at hand for its realization. THE END
