A Full Life: The Works of Charlotte Mason

Moral and Mental Habits make their Mark upon Physical Tissues.––But, practically, everybody knows that the body, and every part of the body, accommodates itself very readily to the uses it is put to: we know that if a child accustom herself to stand on one foot, thus pushing up one shoulder, the habit will probably end in curvature of the spine; that to permit drooping shoulders, and, consequently, contracted chest, is to prepare the way for lung disease. The physical consequences of bad habits of this sort are so evident, that we cannot blind ourselves to the relation of cause and effect. What we are less prepared to admit is, that habits which do not appear to be in any sense physical––a flippant habit, a truthful habit, an orderly habit––should also make their mark upon a physical tissue, and that it is to this physical effect the enormous strength of habit is probably due. Yet when we consider that the brain, the physical brain, is the exceedingly delicate organ by means of which we think and feel and desire, love and hate and worship, it is not surprising that that organ should be modified by the work it has to do; to put the matter picturesquely, it is as if every familiar train of thought made a rut in the nervous substance of the brain into which the thoughts run lightly of their own accord, and out of which they can only be got by an effort of will.
