No doubt many of my hearers will recognize, in the following passages, arguments they may have heard brought forward with triumphant confidence in behalf of some doctrine not yet extinct. No doubt some may have honestly thought they proved something; may have used them with the purpose of convincing their friends, or of silencing the opponents of their favorite doctrine, whatever that might be. But any train of arguments which was contrived for Perkinism, which was just as applicable to it as to any other new doctrine in the same branch of science, and which was fully employed against its adversaries forty years since, might, in common charity, be suffered to slumber in the grave of Perkinism. Whether or not the following sentences, taken literally from the work of Mr. Perkins, were the originals of some of the idle propositions we hear bandied about from time to time, let those who listen judge.
The following is the test assumed for the new practice: “If diseases are really removed, as those persons who have practised extensively with the Tractors declare, it should seem there would be but little doubt of their being generally adopted; but if the numerous reports of their efficacy which have been published are forgeries, or are unfounded, the practice ought to be crushed.” To this I merely add, it has been crushed.
The following sentence applies to that a priori judging and uncandid class of individuals who buy their dinners without tasting all the food there is in the market. “On all discoveries there are persons who, without descending to any inquiry into the truth, pretend to know, as it were by intuition, that newly asserted facts are founded in the grossest errors. These were those who knew that Harvey's report of the circulation of the blood was a preposterous and ridiculous suggestion, and in latter later days there were others who knew that Franklin deserved reproach for declaring that points were preferable to balls for protecting buildings from lightning.”
Again: “This unwarrantable mode of offering assertion for proof, so unauthorized and even unprecedented except in the condemnation of a Galileo, the persecution of a Copernicus, and a few other acts of inquisitorial authority, in the times of ignorance and superstition, affords but a lamentable instance of one of his remarks, that this is far from being the Age of Reason.”
“The most valuable medicines in the Materia Medica act on principles of which we are totally ignorant. None have ever yet been able to explain how opium produces sleep, or how bark cures intermittent fevers; and yet few, it is hoped, will be so absurd as to desist from the use of these important articles because they know nothing of the principle of their operations.” Or if the argument is preferred, in the eloquent language of the Perkinistic poet:
“What though the CAUSES may not be explained,
Since these EFFECTS are duly ascertained,
Let not self-interest, prejudice, or pride,
Induce mankind to set the means aside;
Means which, though simple, are by
Heaven designed to alleviate the woes of human kind.”
This course of argument is so often employed, that it deserves to be expanded a little, so that its length and breadth may be fairly seen. A series of what are called facts is brought forward to prove some very improbable doctrine. It is objected by judicious people, or such as have devoted themselves to analogous subjects, that these assumed facts are in direct opposition to all that is known of the course of nature, that the universal experience of the past affords a powerful presumption against their truth, and that in proportion to the gravity of these objections, should be the number and competence of the witnesses. The answer is a ready one. What do we know of the mysteries of Nature? Do we understand the intricate machinery of the Universe? When to this is added the never-failing quotation,
“There are more things in heaven and earth, Horatio,
Than are dreamt of in your philosophy,”—
the question is thought to be finally disposed of.
Take the case of astrology as an example. It is in itself strange and incredible that the relations of the heavenly bodies to each other at a given moment of time, perhaps half a century ago, should have anything to do with my success or misfortune in any undertaking of to-day. But what right have I to say it cannot be so? Can I bind the sweet influences of Pleiades, or loose the bands of Orion? I do not know by what mighty magic the planets roll in their fluid paths, confined to circles as unchanging as if they were rings of steel, nor why the great wave of ocean follows in a sleepless round upon the skirts of moonlight; nor can I say from any certain knowledge that the phases of the heavenly bodies, or even the falling of the leaves of the forest, or the manner in which the sands lie upon the sea-shore, may not be knit up by invisible threads with the web of human destiny. There is a class of minds much more ready to believe that which is at first sight incredible, and because it is incredible, than what is generally thought reasonable. Credo quia impossibile est,—“I believe, because it is impossible,”—is an old paradoxical expression which might be literally applied to this tribe of persons. And they always succeed in finding something marvellous, to call out the exercise of their robust faith. The old Cabalistic teachers maintained that there was not a verse, line, word, or even letter in the Bible which had not a special efficacy either to defend the person who rightly employed it, or to injure his enemies; always provided the original Hebrew was made use of. In the hands of modern Cabalists every substance, no matter how inert, acquires wonderful medicinal virtues, provided it be used in a proper state of purity and subdivision.
I have already mentioned the motives attributed by the Perkinists to the Medical Profession, as preventing its members from receiving the new but unwelcome truths. This accusation is repeated in different forms and places, as, for instance, in the following passage: “Will the medical man who has spent much money and labor in the pursuit of the arcana of Physic, and on the exercise of which depends his support in life, proclaim the inefficacy of his art, and recommend a remedy to his patient which the most unlettered in society can employ as advantageously as himself? and a remedy, too, which, unlike the drops, the pills, the powders, etc., of the Materia Medica, is inconsumable, and ever in readiness to be employed in successive diseases?”
As usual with these people, much indignation was expressed at any parallel between their particular doctrine and practice and those of their exploded predecessors. “The motives,” says the disinterested Mr. Perkins, “which must have impelled to this attempt at classing the METALLIC PRACTICE with the most paltry of empyrical projects, are but too thinly veiled to escape detection.”
To all these arguments was added, as a matter of course, an appeal to the feelings of the benevolent in behalf of suffering humanity, in the shape of a notice that the poor would be treated gratis. It is pretty well understood that this gratuitous treatment of the poor does not necessarily imply an excess of benevolence, any more than the gratuitous distribution of a trader's shop-bills is an evidence of remarkable generosity; in short, that it is one of those things which honest men often do from the best motives, but which rogues and impostors never fail to announce as one of their special recommendations. It is astonishing to see how these things brighten up at the touch of Mr. Perkins's poet:
“Ye worthy, honored, philanthropic few,
The muse shall weave her brightest wreaths for you,
Who in Humanity's bland cause unite,
Nor heed the shaft by interest aimed or spite;
Like the great Pattern of Benevolence,
Hygeia's blessings to the poor dispense;
And though opposed by folly's servile brood,
ENJOY THE LUXURY OF DOING GOOD.”
Having thus sketched the history of Perkinism in its days of prosperity; having seen how it sprung into being, and by what means it maintained its influence, it only remains to tell the brief story of its discomfiture and final downfall. The vast majority of the sensible part of the medical profession were contented, so far as we can judge, to let it die out of itself. It was in vain that the advocates of this invaluable discovery exclaimed over their perverse and interested
