trouble grows until, by degrees, it is looked upon as a necessity. Then at last, when the trouble has increased until it threatens the interruption of all ordinary occupations, the sufferer seeks a remedy. But the habit of submission has grown too strong, and as long as the disease can be kept within certain bounds, no effort is made to fight it. This is of course one of the commonest experiences in the healing profession. A patient is treated and benefited and seems on the high road to perfect health. Then follows a relapse. The first question put is, “Have you been following the treatment?” and the answer, if the patient is truthful, is “I forgot,” or “I didn’t bother any more about it.” In a recent experience of a medical friend of mine, a patient confessed to having stayed in the house for a week after a certain relapse occurred, although the very essence of the prescription by which he had previously benefited was to be in the fresh air as much as possible. This simply means that the subjective habit of submission has grown so strong that the objective mind, weakened in its turn by the neglect of its guiding functions, is unable to conquer it. No prescription or course of treatment can have any effect upon such a patient as this, unless the subjective habit can be brought within the sphere of conscious control. In other cases this apparent lack of desire for health is due to an attachment to some dearly loved habit, which must be given up if the proper functions of the body are to be resumed. It may be a habit of petty self-indulgence or one that is imminently threatening the collapse of the vital processes, but the attachment to it is so strong that the enfeebled objective mind prefers to hold to the habit and risk death sooner than make the effort of opposing it. Even in cases where no harm can be traced directly to a markedly influencing habit, the general all-pervading habit of lassitude or inertia is so strong that any régime which may be prescribed is distasteful if it involves, as it must, the exercise of those powers which have been allowed to fall more or less into disuse. Space will not permit of my giving further instances of the predisposing habit, but very little introspection on the part of my readers should enable them to diagnose their own peculiar mental habits, the first step towards being rid of them. We must always remember that the vast majority of human beings live very narrow lives, doing the same thing and thinking the same thoughts day by day, and it is this very fact that makes it so necessary that we should acquire conscious control of the mental and physical powers as a whole, for we otherwise run the risk of losing that versatility which is such an essential factor in their development. If, at this point, the reader feels inclined to analyse these habits and to set about a control of them, I will give him one word of preliminary advice, “Beware of so-called concentration.”
