Descartes observes, that the soul is so much influenced by the constitution of our bodily organs, that if it were possible to find out a method of increasing our penetration, it should certainly be sought for in medicine, the connexion between the body and mind, is, in fact, so strong, that it is difficult to conceive how one of them should act, and the other not be sensible, in a greater or less degree, of that action. The organs of sense, by which we acquire all our ideas of external objects, when acted upon, convey the subject of thought to the nervous fibres of the brain; and while the mind is employed in thinking, the part of the brain is in a greater or less degree of motion; a large quantity of blood is transmitted to the brain, the action of the arteries become increased, and the nervous system sensibly affected.
Plato has remarked, with reference to the influence of the mind on the corporeal frame, "Where the action of the soul is too powerful, it attacks the body so powerfully that it throws it into a consuming state; if the soul exerts itself in a peculiar manner on certain occasions, the body is made sensible of it, for it becomes heated and debilitated." An Italian physician also observes on this subject, that the union of the soul with the body is so intimate, that they reciprocally share the good or evil which happens to either of them. The mind cannot put forth its powers when the body is tired with inordinate exercise and too close application to study destroys the body by dissipating the animal spirits which are necessary to recruit it.2
The knowledge of the influence of the passions of the mind over the bodily functions, is of ancient date. Plato, in his "Timaeus," states it as his firm conviction, that the spirit exerted a marked influence in producing disease. This opinion was afterwards revived by Helmont, Hesper Doloeus, and Stahl; the latter plainly says, that the rational soul presides over and directs the animal functions. In this doctrine he was followed by Nichols, in his "Anima Medica." According to the doctrines of Stahl, the disorders of the body proceed principally from the mind; and, according as it is variously affected, it produces different effects (diseases.) Hence, when the mind, which animates the most robust and best organized body, is violently agitated by fright, rage, grief, vehement desire, or any other passion, whether sudden, or attended by long and painful sensations, the body manifestly suffers, and a variety of diseases, as apoplexy, palsy, madness, fever, and hysterics, may be the consequence. If this be true, an attention to the regulations of the mind is of much more importance than physicians seem disposed to admit. The poet of health justly says,
"'Tis the great art of life to manage well
The restless mind."
In the course of this vitally important and deeply-interesting subject of inquiry, it is not my intention to enter into any metaphysical discussion respecting the inscrutable and mysterious union existing between matter and mind, or to endeavour to point out the manner in which the body influences the mind, and the mind the body. Such subjects we do not think to be legitimate objects of inquiry. The medical philosopher is engaged in less obscure and less uncertain researches; he does not attempt to solve the question regarding the intimate union subsisting between the natural and intellectual portions of our nature, but he wisely confines himself to an attentive examination of the phenomena which result from that union. Man is compounded of a soul and body, so closely united, not identified, that they frequently struggle and occasionally overpower each other. Sometimes the mind ascends the throne and subdues, in a moment, the physical energies of the most powerful of her subjects. At other times the body gains the ascendency, and lays prostrate before her the mightiest of human intellects. Instances illustrative of both propositions are of daily occurrence. It has been said of Sophocles, that being desirous of proving that at an advanced age he was in full possession of his intellectual faculties, he composed a tragedy, was crowned, and died through joy. The same thing happened to Philippides, the comic writer. M. Juventius Thalma, on being told that a triumph had been decreed to him for having subdued Corsica, fell down dead before the altar at which he was offering up his thanksgiving. Zimmerman, in his work on Experience in Physic, has related the circumstance of a worthy family in Holland being reduced to indigence; the elder brother passed over to the East Indies, acquired considerable fortune there, and returning home presented his sister with the richest jewel: the young woman, at this unexpected change of fortune became motionless and died. The famous Forquet died on being told that Louis XIV. had restored him to his liberty. It is also related of Diodorus Chronos, who was considered as the most subtle logician of the time of Ptolemy Soter, that Stilbo one day in the presence of the king, proposed a question to him, to which he was unable to reply. The king, willing to cover him with shame, pronounced only one part of his name, and called him ovos, ass, instead of Chronos. Diodorus was so much affected at this as to die soon afterwards.
Perhaps there is not a more remarkable instance on record showing, in a melancholy though forcible light, the dominion of mind over the material frame, than the circumstances which attended the death of John Hunter. This distinguished surgeon and physiologist died in a fit of enraged passion; and, what is somewhat extraordinary, he had often predicted that such excitement would prove fatal to him. He died at St. George's Hospital, Oct. 16, 1793, under these circumstances: being there in the exercise of his official duty as surgeon, he had a warm dispute with Dr. Pearson, on a professional subject; upon which he said, "I must retire, for I feel an agitation which will be fatal to me if I increase it." He immediately withdrew into an adjoining room; but Dr. Pearson, not being willing to give up his argument, followed him, which so annoyed Hunter, that he vehemently exclaimed, "You have followed me on purpose to be the death of me! You have murdered me!" and instantly fell and expired! Mrs. Byron, the mother of the noble bard, is said to have died in a fit of passion. Mr. Moore, in his life of Lord Byron, in speaking of Mrs. Byron's illness, says,—"At the end of July her illness took a new and fatal turn; and so sadly characteristic was the close of the poor lady's life, that a fit of ague, brought on, it is said, by reading the upholsterer's bills, was the ultimate cause of her death." A somewhat similar circumstance is recorded of Malbranche. The only interview that Bishop Berkley and Malbranche had was in the latter philosopher's cell, when the conversation turned upon the non-existence of matter, and Malbranche is said to have exerted himself so much in the discussion that he died in consequence. Sanctorius relates an instance of a famous orator, who so far exerted his mind in delivering an oration that he became, in a few hours, quite insane.
The effect of a too close application of mind to study on the bodily health has long been a matter of common observation. The Roman orator, Cicero, points out forcibly the dangers arising from inordinate exertion of mind; and he has laid down some rules for guarding against the effects of study. M. Van Swieten, in alluding to this subject, relates the case of a man whose health was severely injured, by what he calls "literary watchings." Whenever he listened with any attention to any story, or trifling tale, he was seized with giddiness; he was in violent agonies whenever he wanted to recollect any thing which had slipped his memory; he oftentimes fainted away gradually, and experienced a disagreeable sensation of lassitude. Rousseau has very justly remarked, that excessive application of mind "makes men tender, weakens their constitutions, and when once the body has lost its powers, those of the soul are not easily preserved. Application wears out the machine, exhausts the spirits, destroys the strength, enervates the mind, makes us pusillanimous, unable either to bear fatigue, or to keep our passions under."3
Shakspeare appears to have formed a just conception of the great injury which the corporeal frame experiences from a too close application of mind. The immortal bard observes,—
"–Universal plodding poisons up
The nimble spirits in the arteries
