"The states of the body are infinitely various. All these different states differently affect the mind. They are causes, and their effects have all the variety which mark the causes that produce them. If then different conditions of the body differently affect the mind, some electrifying, and others paralyzing its energies, what duty can be plainer than _to preserve the body in that condition which will most favorably affect the mind_? If the Maker of both was infinitely wise, then the highest _permanent_ perfection of the mind can be found only in connection with the most healthful state of the body. Has infinite wisdom established laws by which the best condition of the mind is _permanently_ connected with any other than the best condition of the body? When all the bodily functions are perfectly performed, the mind must be in a better state than when these functions are imperfectly performed. And now I ask, is not that system of education fundamentally defective, which makes no provision for putting the body in its best condition, and for keeping it in that condition? A system which expends its energies upon the mind alone, and surrenders the body either to the irregular promptings of perverted instinct, or to the hap-hazard impulses of chance or necessity? A system which aims solely at the development of mind, and yet overlooks those very principles which are indispensable to produce that development, and transgresses those very laws which constitute the only ground-work of rational education? Such a system sunders what God has joined together, and impeaches the wisdom which pronounced that union good. It destroys the symmetry of human proportion, and makes man a monster. It reverses the {247} order of the constitution; commits outrage upon its principles; breaks up its reciprocities; makes war alike upon physical health and intellectual energy, dividing man against himself; arming body and mind in mutual hostility, and prolonging the conflict until each falls a prey to the other, and both surrender to ruin.
