_Serve if you hope to survive_ would be a good motto. You cannot survive if you do not serve--all of you. I like that figure of the cell which is a part of the race-being. It is the way I see you. Just a word about nervous diseases. Yes, it is related to what I have been saying. When at last the let-up comes after the unnatural strain of war, the minds of men in going back, or in attempting to go back to their normal state, may find themselves unable immediately to adjust to the changed conditions. For a long time the brains of men and women have been stimulated by the coffee of concerted action; when they are thrown back on themselves they may relax too much. Or, on the other hand, an unnatural excitement may drive them into all kinds of excesses. Have you ever seen victims of mania who could not rest, who had lost the ability to rest? They walk up and down, and drum with their feet, and clench their hands. So many men and women may be, after this war. There is certain to be an excess of love excitement, and work is a good panacea for that complaint. Then again, after years of war, years in which many have not known in the morning whether they would be alive at night, they may retain the habit of dread. They may fear to rest and fear to relax. Thus they may welcome any excitement, as a substitute for the stimulus to which they have been accustomed. That is another reason why I would send Americans to labor with the laborers of Europe. Not that the American working man is phlegmatic, far from it; but with his mind unaccustomed to fear anything, except the loss of his job and consequent hunger, he will have an effect of confidence and hope on those around him. The American likes to feel that he is leading, and in what better way can he indulge that propensity than in leading his associates to hope? You have no idea--you cannot have an idea--of the great depression that will follow this war for a short while. It will be the relaxation, the letting go. Always after war the ebb-tide is followed by great activity; but it is that ebb-tide which we have to consider. You in America will feel it. You have become accustomed to seeing gold flow towards these shores. When the stream lessens, you will have to combat the tendency to fear that lessening. Panics are like personal fear, intensified by mass. The world is drawing close together, and what influences a part influences the whole. After the war will also come an opening of the psychic senses of men, everywhere. This, while good in itself, may become an added danger. Prophets, true and false, will arise everywhere, with many remedies for the diseases of souls and of bodies.
