All this world is heavy with the promise of greater things, and a day will come, one day in the unending succession of days, when beings, beings who are now latent in our thoughts and hidden in our loins, shall stand upon this earth as one stands upon a footstool, and shall laugh and reach out their hands amid the stars. THE ART _of_ LIFE SERIES EDWARD HOWARD GRIGGS, Editor "The aim of this series of brief books is to illuminate the never-to-be-finished art of living. There is no thought of solving the problems or giving dogmatic theories of conduct. Rather the purpose is to bring together in brief form the thoughts of some wise minds and the insight and appreciation of some deep characters, trained in the actual world of experience but attaining a vision of life in clear and wide perspective. Such books should act as a challenge to the reader's own mind, bringing him to a clearer recognition of the problems of his life and the laws governing them, deepening his insight into the wonder and meaning of life and developing an attitude of appreciation that may make possible the wise and earnest facing of the deeps, dark or beautiful, in the life of the personal spirit.--_From the Editor's Introduction to the Series, printed in full in "The Use of the Margin."_ _Volumes ready:_ WHERE KNOWLEDGE FAILS By Earl Barnes THE SIXTH SENSE.
