Parents must also remember that over-solicitous attention on their part is bound to react to the disadvantage of the child. The story is told of Phillips Brooks that, when a child, he put a newly sharpened pencil into his mouth further and further until it slipped down his throat. He asked his mother what would happen if anyone should swallow a pencil. She answered that she supposed it would kill him. Phillips kept silence, and his mother made no further inquiry. This incident would indicate that Phillips Brooks had already, as a child, attained a mental equipoise which the average individual hardly achieves in a lifetime. The story appeals to me no less as evidence of self-control on the part of the mother; and I like to imagine that she suppressed the question a startled parent naturally would ask, realizing that no amount of worry would recall the pencil if he had swallowed it, and that nothing was to be gained by overturning the household, or by giving the boy an example of agitation sure to react to the detriment of the mind unfolding under her supervision. Unless, therefore, the facts of this story have become distorted by imagery, it shows exceptional heredity and unusual training. Not every one can claim such heredity, and not every one can look back on such training; but it is not too much to say that every one can so direct his thoughts and so order his actions as gradually to attain a somewhat higher level of self-control than either his mental endowment or his early training would have promised. For mental training is no more limited to feats of memory, and to practice in the solution of difficult problems, than is physical training comprised in the lifting of heavy weights in harness. In fact, such exercises are always in danger of leaving the mental athlete intellectually muscle-bound, if I may use such an expression; whereas the kind of training I have in mind tends to establish mental poise, to improve the disposition, to fit the mind (and indirectly the body) better to meet the varied exigencies of daily life, and to help the individual to react in every way more comfortably to his surroundings. I have only hinted at the detailed suggestions by which the worry habit and allied faulty mental tendencies may be combated. The obsessive who is able to alter his ideals and systematically pursue the line of thought here sketched will himself find other directions in which control can be exercised. It is true that no one is likely to reach any of the extreme degrees of incapacity we have considered unless he is naturally endowed with a mind predestined to unbalance. At the same time any of us who have a nervous temperament ever so slightly above the average of intensity will do well to check these tendencies as far as possible in their incipiency, realizing that no physical evil we may dread can be worse than the lot of the confirmed hypochondriac or the compulsively insane.
