Briefly, as I see it, the subconsciousness in this application is only a synonym for that rigid routine we finally refer to as habit, this rigid routine being the stumbling-block to rapid adaptability, to the assimilation of new ideas, to originality. On the other hand, the consciousness is the synonym for mobility of mind, that mobility which the subconscious control checks and impedes, mobility which will obtain for us physical regeneration and a mental outlook that will make possible for us a new and wider enjoyment of those powers which we all possess, but which are so often deliberately stunted or neglected. Consider this point also in its application to the case of John Doe, cited in my second chapter. If the mental attitude of that individual had been changed, and he had learned to use his muscles consciously; if, instead of automatically performing a set of muscle-tensing exercises, he had devoted himself to apprehending the control and co-ordination of his muscles, he could have carried his knowledge into every act of his life. In his most sedentary occupations he could have been using and exercising his muscular system without resort to any violent contortions, waving of the arms or kicking of the legs, and I cannot but think that he could better have employed the hours spent in this manner by taking a walk in the open air or by occupying himself with some other form of natural exercise. Still, if in his case certain mild forms of exercise at certain times were necessary, such exercises should have employed his mental and physical powers, and through these agencies he should have used his muscular mechanism in such a way that its uses could have been applied to the simplest acts, such as sitting on a stool and writing at a desk. There would then have been no question of what we have termed “civil war” within his body; the whole physical machinery would have been co-ordinated and adapted to his way of life.
