In adolescence, in early adult life, there comes a heavy strain on these two ideas, and unless we have built as we ought, some portion of the edifice will be in danger of falling. The point is, that we must somehow manage to build these two ideas together; we must adjust and fit them together, giving to each of them its due place in the house of life, not opposing but conjoining them to each other, as a builder conjoins bricks and mortar. It is a true saying, “The reasonable soul and flesh is one man.” Please observe that they not _are_, but _is_, one man; they are so closely united that they _is_ one man. It follows, that what we call temptation addresses itself not to the flesh alone, but also to the reasonable soul. Consider the predicament of a young man who up to now has, as we call it, “kept straight.” All round him, day after day, newspapers and books and shop windows and theatres, and other men’s talk, and the look of the crowd in the streets, are alluding to it. His pride is wounded, and the more he tries not to think of it, the more it hurts. All young men covet and pursue the experiences of life; he is vexed and resentful that he should be thus incomplete. He has given up what a young man most hates to give up: he has given up something which would make him just like other young men. Not only his body, but his reasonable soul, is restless and impatient. That which impels him to the edge of temptation is not his animal nature but his whole human nature. Other motives, alike in boys and in girls, are vanity, sentimentality, and intolerance, especially in these tremendous days, of the monotonous narrowness of their work and the fretful discipline of their homes. And there are some boys and girls――happily it is a small minority――who are so passionate and so wilful that they hardly stop to reckon what they are doing. Of course, we have some antidotes against temptation. One of them is the right employment of mind and body; but the mind must not be employed at haphazard, and the body must not be over-fatigued. The employment of the mind must have a touch of refinement or fastidiousness: things which are lurid and vulgar must be recognised for what they are: the boys and girls must be fond of “good form”; they must be picksome over books and theatres and picture-palaces and friendships. The employment of the body must have a touch of discipline or training: outdoor exercise, athletics in moderation, fresh air, plain food, cold water. If I could be a little boy again, I would join the Boy Scouts; if I could be a young man again, I would get on without alcohol and cigarettes.
