AEsop, a most excellent author, and of whom few men discover all the graces, pleasantly represents to us the tyrannical authority physicians usurp over poor creatures, weakened and subdued by sickness and fear, when he tells us, that a sick person, being asked by his physician what operation he found of the potion he had given him: "I have sweated very much," says the sick man. "That's good," says the physician. Another time, having asked how he felt himself after his physic: "I have been very cold, and have had a great shivering upon me," said he. "That is good," replied the physician. After the third potion, he asked him again how he did: "Why, I find myself swollen and puffed up," said he, "as if I had a dropsy."—"That is very well," said the physician. One of his servants coming presently after to inquire how he felt himself, "Truly, friend," said he, "with being too well I am about to die."
There was a more just law in Egypt, by which the physician, for the three first days, was to take charge of his patient at the patient's own risk and cost; but, those three days being past, it was to be at his own. For what reason is it that their patron, AEsculapius, should be struck with thunder for restoring Hippolitus from death to life:
"Nam Pater omnipotens, aliquem indignatus ab umbris
Mortalem infernis ad lumina surgere vitae,
Ipse repertorem medicinae talis, et artis
Fulmine Phoebigenam Stygias detrusit ad undas;"
["Then the Almighty Father, offended that any mortal should rise to
the light of life from the infernal shades, struck the son of
Phoebus with his forked lightning to the Stygian lake."
—AEneid, vii. 770.]
and his followers be pardoned, who send so many souls from life to death? A physician, boasting to Nicocles that his art was of great authority: "It is so, indeed," said Nicocles, "that can with impunity kill so many people."
As to what remains, had I been of their counsel, I would have rendered my discipline more sacred and mysterious; they begun well, but they have not ended so. It was a good beginning to make gods and demons the authors of their science, and to have used a peculiar way of speaking and writing, notwithstanding that philosophy concludes it folly to persuade a man to his own good by an unintelligible way: "Ut si quis medicus imperet, ut sumat:"
"Terrigenam, herbigradam, domiportam, sanguine cassam."
["Describing it by the epithets of an animal trailing with its slime
over the herbage, without blood or bones, and carrying its house
upon its back, meaning simply a snail."—Coste]
It was a good rule in their art, and that accompanies all other vain, fantastic, and supernatural arts, that the patient's belief should prepossess them with good hope and assurance of their effects and operation: a rule they hold to that degree, as to maintain that the most inexpert and ignorant physician is more proper for a patient who has confidence in him, than the most learned and experienced whom he is not so acquainted with. Nay, even the very choice of most of their drugs is in some sort mysterious and divine; the left foot of a tortoise, the urine of a lizard, the dung of an elephant, the liver of a mole, blood drawn from under the right wing of a white pigeon; and for us who have the stone (so scornfully they use us in our miseries) the excrement of rats beaten to powder, and such like trash and fooleries which rather carry a face of magical enchantment than of any solid science. I omit the odd number of their pills, the destination of certain days and feasts of the year, the superstition of gathering their simples at certain hours, and that so austere and very wise countenance and carriage which Pliny himself so much derides. But they have, as I said, failed in that they have not added to this fine beginning the making their meetings and consultations more religious and secret, where no profane person should have admission, no more than in the secret ceremonies of AEsculapius; for by the reason of this it falls out that their irresolution, the weakness of their arguments, divinations and foundations, the sharpness of their disputes, full of hatred, jealousy, and self-consideration, coming to be discovered by every one, a man must be marvellously blind not to see that he runs a very great hazard in their hands. Who ever saw one physician approve of another's prescription, without taking something away, or adding something to it? by which they sufficiently betray their tricks, and make it manifest to us that they therein more consider their own reputation, and consequently their profit, than their patient's interest. He was a much wiser man of their tribe, who of old gave it as a rule, that only one physician should undertake a sick person; for if he do nothing to purpose, one single man's default can bring no great scandal upon the art of medicine; and, on the contrary, the glory will be great if he happen to have success; whereas, when there are many, they at every turn bring a disrepute upon their calling, forasmuch as they oftener do hurt than good. They ought to be satisfied with the perpetual disagreement which is found in the opinions of the principal masters and ancient authors of this science, which is only known to men well read, without discovering to the vulgar the controversies and various judgments which they still nourish and continue amongst themselves.
Will you have one example of the ancient controversy in physic? Herophilus lodges the original cause of all diseases in the humours; Erasistratus, in the blood of the arteries; Asclepiades, in the invisible atoms of the pores; Alcmaeon, in the exuberance or defect of our bodily strength; Diocles, in the inequality of the elements of which the body is composed, and in the quality of the air we breathe; Strato, in the abundance, crudity, and corruption of the nourishment we take; and Hippocrates lodges it in the spirits. There is a certain friend of theirs,—[Celsus, Preface to the First Book.]—whom they know better than I, who declares upon this subject, "that the most important science in practice amongst us, as that which is intrusted with our health and conservation, is, by ill luck, the most uncertain, the most perplexed, and agitated with the greatest mutations." There is no great danger in our mistaking the height of the sun, or the fraction of some astronomical supputation; but here, where our whole being is concerned, 'tis not wisdom to abandon ourselves to the mercy of the agitation of so many contrary winds.
Before the Peloponnesian war there was no great talk of this science. Hippocrates brought it into repute; whatever he established, Chrysippus overthrew; after that, Erasistratus, Aristotle's grandson, overthrew what Chrysippus had written; after these, the Empirics started up, who took a quite contrary way to the ancients in the management of this art; when the credit of these began a little to decay, Herophilus set another sort of practice on foot, which Asclepiades in turn stood up against, and overthrew; then, in their turn, the opinions first of Themiso, and then of Musa, and after that those of Vectius Valens, a physician famous through the intelligence he had with Messalina, came in vogue; the empire of physic in Nero's time was established in Thessalus, who abolished and condemned all that had been held till his time; this man's doctrine was refuted by Crinas of Marseilles, who first brought all medicinal operations under the Ephemerides and motions of the stars, and reduced eating, sleeping, and drinking to hours that were most pleasing to Mercury and the moon; his authority was soon after supplanted by Charinus, a physician of the same city of Marseilles, a man who not only controverted all the ancient methods of physic, but moreover the usage of hot baths, that had been generally and for so many ages in common use; he made men bathe in cold water, even in winter, and plunged his sick patients in the natural waters of streams. No Roman till Pliny's time had ever vouchsafed to practise physic; that office was only performed by Greeks and foreigners, as 'tis now amongst us French, by those who sputter Latin; for, as a very great physician says, we do not easily accept the medicine we understand, no more than we do the drugs we ourselves gather. If the nations whence we fetch our guaiacum, sarsaparilla, and China wood, have physicians, how great a value must we imagine, by the same recommendation of strangeness, rarity, and dear purchase, do they set upon our cabbage and parsley? for who would dare to contemn things so far fetched, and sought out at the hazard of so long and dangerous a voyage?
