Instead, it is here our intention to go to the object itself, to the putting of the body in such condition as will render it not only, from its inherent health, far less liable to be attacked by disease, but as will make it as far as possible a fit servant of the will, ready and prompt to act, unclogged by the débris of excess, far more capable of work than was its wont, and capable, too, of better work. It will thus be saved not from disease only, but from a continual condition of being slightly unfit, even in the case of those who (rightly in comparison with the general average of health) consider themselves healthy. Nor is such a benefit, if obtainable, limited to the present, for historically it is perfectly certain that both the bodily and mental health of any one generation depend very largely on the condition of the previous generation; since habits which are the progenitors of tendencies can be formed by any one in whom the will-power is ever so little alive. Further, in this wonderful intermingling of mind and body which we know as man, there is no change possible to one which does not affect the other, and just as deficiencies of mind produce physical ill-health, so a more healthy and cleanly condition of body produces a more healthy and cleanly mind. For who shall say of how much immorality bodily stimulants and overfeeding are not the lawful and genuine parents, or for how much depression, morose spirits, and stagnated languor of mind that organ known as the liver is not entirely responsible?
