As many as there may be of these partial activities (and is not every beat of the pulse the result perhaps of thousands?) so many will be the obscure sensations crowding upon the soul, each one of which indicates perfection. Out of this confused complexity arises entire sensation of the animal harmonies, that is, the highest possible combined sensation of animal pleasure, which ranges itself, as it were, alongside of the original intellectual or moral sensation, which this addition infinitely increases. Thus is every agreeable affection the source of countless bodily pleasures. This is most evidently confirmed by the examples of sick persons who have been cured by joy. Let one whom a terrible home-sickness has wasted to a skeleton be brought back to his native land, and the bloom of health will soon be his again; or let us enter a prison in which miserable men have for ten or twenty years inhabited filthy dungeons and possess at last barely strength to move,--and let us tell them suddenly they are free; the single word of freedom will endow their limbs with the strength of youth, and cause dead eyes to sparkle with life. Sailors, whom thirst and famine have made their prey during a long voyage, are half cured by the steersman's cry of "Land!" and he would certainly greatly err who ascribed the whole result to a prospect of fresh food. The sight of a dear one, whom the sufferer has long desired to see, sustains the life that was about to go, and imparts strength and health. It is a fact, that joy can quicken the nervous system more effectually than all the cordials of the apothecary, and can do wonders in the case of inveterate internal disorders denied to the action of rhubarb and even mercury. Who then does not perceive that the constitution of the soul which knows how to derive pleasure from every event and can dissipate every ache in the perfection of the universe, must be the most beneficial to the whole organism? and this constitution of the soul is--virtue. S 14.--Mental pain undermines the Welfare of the Whole Organisms. In the very same way, the opposite result is brought about by a disagreeable affection of the mind. The ideas which rule so intensely the angry or terrified man may, as rightly as Plato called the passions a fever of the soul, be regarded as convulsions of the organ of thought. These convulsions quickly extend through the nervous system, and so disturb the vital powers that they lose their perfection, and all organic actions lose their equilibrium. The heart beats violently and irregularly; the blood is so confined to the lungs that the failing pulse has barely enough to sustain it. The internal chemical processes are at cross-purposes; beneficent juices lose their way and work harm in other provinces, while what is malignant may attack the very core of our organism. In a word, the condition of the greatest mental distress becomes the condition of the greatest bodily sickness.
