How fortunate it would have been for man had the "Deity" given that as his first and best thought to the world! Then, indeed, would he have been the friend of man. We cannot preserve our health without observing all the other commandments--of temperance, purity, sanity, self possession, contentment, and serenity of mind. "Behold I bring unto you health" ought to be the glad tidings of salvation. Give us that, and all the rest will be added unto us. Health is the foundation of character. If the foundation is insecure--if we have inherited disease and corruption, we can be sound, neither in our thoughts nor in our actions. The time may come when to be sickly will be considered a crime. A revolution in our feelings in this matter is already taking place. Formerly it was thought that the path to self-development is through sorrow and suffering, and that the sick were the saints. The verdict of science today, which has been confirmed by the growing experience of man, is that pleasurable activity is the most wholesome environment for man. Happiness has upon human nature the same effect that the sunshine has upon the soil. Man is a failure if he is not happy. The highest accomplishment is the ability to enjoy life. To those who say that service or usefulness is the noblest aim of life, we answer, "Why should those who serve the noblest ends of life be unhappy?" But let me first present to you the answer which one of America's best known psychologists, Prof. William James, of Harvard, gives to this most interesting question. Prof. James is a teacher not only of the young men in one of our leading Universities, but his ideas have become a part of the furniture of the American mind. Both his thought and the candor with which he expresses himself have secured for him a large following. Prof. James has an engaging style. Not that he is not also a profound thinker, but his sentences are as symmetrical as they are solid. He writes to be understood. That, I take it, is the secret of the masters of style. The gods always speak from behind "clouds and darkness." That explains why it is so difficult to understand what they say. But the great teachers permit no screens, draperies, curtains, or hangings of any sort to come between them and the public. There is nothing hidden about their thoughts. Neither do they speak in parables. Whoever can not make himself understood should hold his peace.
