After spending the best part of my life in the study of the liberal arts and sciences, and in the company of wise men and judicious scholars, I was compelled, as the result of my observation of mankind, to arrive at the melancholy conclusion that the hearts of most persons are set either on ambitious and vainglorious projects, on sensual pleasures, or on the accumulation of wealth by all and any means; and that few care either for God or for virtue. At first I did not quite know whether to become a disciple of the laughing or of the weeping philosopher, or whether to join in the exclamation of the wise Prince of Israel: “All things are vanity.” But at length the Bible and experience taught me to take refuge in the study of the hidden secrets of Nature, whether pursued at home, by means of books or abroad, in the Great Volume of the World. Now, the more I drank of the mighty fount of knowledge, the more painfully my thirst, like that of Tantalus, seemed to increase. I had heard that there was a bird called Phoenix, the only one of its kind in the whole world, whose feathers and flesh constitute the great and glorious medicine for all passion, pain, and sorrow; which also Helena, after her return from Troy, had presented in the form of a draught to Telemachus, who thereupon had forgotten all his sorrows and troubles. This bird I could not indeed hope to obtain entire, but I was seized with an irresistible longing to become possessed of at least one of its smallest feathers; and for this unspeakable privilege I was prepared to spend all my substance, to travel far and wide, and to endure every hardship. There was, of course, much to discourage me. Some people denied the very existence of this bird; others laughed at my faith in its wonder-working properties. I was thus brought for a time to regard all that Tacitus, Pliny, and all other writers have said as fabulous, and to doubt whether, after all, the different narcotics and opiates were not a better remedy for anger and sorrow than the supposed virtues of the Phoenix. Moreover, I had heard of the simple method of curing these mental ailments suggested by a certain wise man to Augustus, whom he bade run through the twenty-four letters before saying anything whenever he was angry; and this suggestion appeared to supersede all other remedies. I had also read the books of those moral philosophers who undertake to prescribe an effective remedy for every disease of the mind. But after giving all these boasted specifics a fair trial, I found, to my dismay, that they were of little practical use. In many cases, the causes of mental maladies appeared to be material, and to consist in an excess or defect of the bile, or of some other bodily substance; in all these cases a medical treatment seemed to be indicated; whence Galen, that prince among physicians, was led to believe that character depends on temperaments of the body.
As a soldier may lose all his bravery and strength by being starved and confined in a close prison, so even a good person may yield to anger, simply through some vicious habit of body. This opinion is most reasonable in itself, and is borne out, amongst other things, by the testimony which is given by Arnold of Villanova, in that book of his where he sets forth the virtues of all medicines by means of tables of the four qualities: “The medicines that conduce to intellectual excellence are those which strengthen the digestion, and nourish the brain and the principal vitals, purging out all superfluities, purifying the blood. and preventing the ascent of vapours to the brain; hence you will find that many medical writers speak of their medicines as productive of a direct effect upon the mind, when it is only through the medium of the stomach, the brain, the blood, the liver, etc., that they tend to brighten the intellectual faculties, by improving the general health of the brain, and quickening all processes of the body, that you may say they are productive of joy, because they tend to strengthen the chief limbs, purify the blood, and produce good animal spirits. Other medicines “lead to Paradise,” as they dispose the heart to charity and to every good work. by their action upon the blood. Some medicinal herbs have the power of exciting love, by increasing and clarifying the blood, and thus quickening the sexual instinct; while others make men chaste and religious, by inducing poverty and frigidity of blood, and taking away the edge of all sensual appetite. In the same way, it is possible, by means of certain drugs, to make men stupid and insane, as men are rendered dull and stolid by drinking, too much wine. You may also notice, sometimes, that after eating a certain kind of food, men become light-hearted, joyous, and inclined to dance and sing- though they are ordinarily staid and grave persons — while other kinds of food have a contrary effect upon them. Thus, a physician has power to make a miser liberal, a chaste person lascivious, a timid person bold, simply by changing the complexion of his vital juices. Such are the wonderful secrets of the medical Art, though of course, they are hidden from the foolish and the ignorant. There are a great many infatuated persons who will not believe that medicine can do anything but cure a headache; but such people know little of the resources of this science. Hippocrates forbad the physicians whom he taught to reveal these secrets; and it was a wise prohibition.” A little further on the same writer says: ” What medicine can produce greater heat than anger? or chill the body more than fear? or invigorate the nerves more thoroughly than joy? or nourish and comfort more gently than hope? And what more certain cause of death is there than despair?” These are the words of the philosopher, and they shew that medicine may, through the body, cure the mind, and thus supply a remedy for anger as well as other mental disturbances. It is true that if there is a remedy for anger, it would, in the present state of the world, hardly be very highly esteemed. Still it would calm the passions of individuals, although other persons might not recognise its value. But that which men do. not care to have just now, may one day be in great demand. Such is the vicissitude of all things human. Galen once said that the savages of England and Germany were as hostile to the science of Medicine as they were ignorant of it. But now the descendants of Galen’s countrymen are sunk in barbarism, while the English and Germans are the most skilful physicians in the world. Thus it seems very likely that this Remedy may be one day in great request, especially when we consider its vast utility, and the innumerable evils which anger brings upon men.
