"In different periods of life, the mind waxes and wanes with the body; in youth, cheerful, full of daring, quick to see, and keen to feel; in old age, desponding, timid, perception dim, and emotion languid. When the blood circulates with unusual energy, the coward rises into a hero; when it creeps feebly, the hero sinks into a coward. The effects produced by the different states of the mind upon the body, are equally sudden and powerful. Plato used to say that all the diseases of the body proceed from the soul. [With more of propriety, we think, it may be said, that at least three-fourths of the diseases that afflict humanity, arise from an injudicious treatment of the body. But be this as it may, the fact is too obvious to be disputed, that the mind acts powerfully upon the animal frame.] The expression of the countenance _is mind visible_. _Bad news_ weaken the action of the heart, oppress the lungs, destroy appetite, stop digestion, and partially suspend all the functions of the animal system. An emotion of shame flushes the face; fear blanches it; joy illuminates it; and an instant thrill electrifies a million of nerves. Powerful emotion often kills the body at a stroke. Chilo, Diagoras, and Sophocles died of joy at the Elean games. The news of a defeat killed Philip V. One of the Popes died of an emotion of the ludicrous, on seeing his pet monkey robed in pontificals, and occupying the chair of state. The door-keeper of Congress expired upon hearing of the surrender of Cornwallis. Pinckney, Emmet, and Webster are recent instances of individuals who have died either in the midst of an impassioned burst of eloquence, or when the deep emotion that had produced it had suddenly subsided. Indeed, the experience of every day demonstrates that the body and mind are endowed with such mutual susceptibilities, that each is alive to the slightest influence of the other. What is the common-sense inference from this fact? Manifestly this--that the body and the mind _should be educated together_.
