“ Often have infatuation and fanaticism, hatred and revenge, engendered by an overwhelming fear of death, spread fire and flames throughout the world. Famine and diseases, among which may be instanced the fiery plague of St. Anthony, were no less powerful in calling forth the chivalrous spirit of the crusades than the enthusiastic eloquence of Peter the Hermit—the Black Death brought thousands to the stake, and aroused the fearful penances of the Flagellants—while the oriental leprosy cast a gloomy shade over society throughout the whole course of the middle ages. ”

“ Had there been in Roettingen a physician at hand from the commencement, well skilled in medical history, and who would have adopted the old English treatment of the Sweating Sickness, this new fever would have appeared but as a perfectly mild disease, and would certainly have carried off but few of the inhabitants of this peaceful little town. As it was, however, the scenes of Lübeck and Zwickau were renewed, and it seemed as if the innumerable victims to the hot treatment, and to Kegeler’s truculent medical work, had descended to the grave in vain. ”

“ Not many years ago (O best of patrons) a man most advised in every branch of life; one who has deserved well of the company of the learned; bound by the ties of family to yourself; a most shining light of the University of Cambridge; its jewel and glory, John Caius, wrote not without elegance to Conrad Gesner, a man exceedingly skilled and sagacious in the investigation of recondite matters; a man armed with everything that relates to natural history; the same man wrote an epitome concerning British dogs, not so concise as elegant and useful ”

“ Here a wide, and almost unfathomable chasm occurs in the science of medicine, which, in this age of mature judgment and multifarious learning, cannot, as formerly, be overlooked. History alone can fill it up; she alone can give to the doctrine of diseases that importance without which its application is limited to occurrences of the moment; whereas the development of the phenomena of life, during extensive periods, is no less a problem of research for the philosopher, who makes the boundless science of nature his study, than the revolutions of the planet on which we move. ”

“ Anthony’s fire was the dread of town and country; and that disgusting disease, the leprosy, which, in consequence of the crusades, spread its insinuating poison in all directions, snatched from the paternal hearth innumerable victims who, banished from human society, pined away in lonely huts, whither they were accompanied only by the pity of the benevolent and their own despair. All these calamities, of which the moderns have scarcely retained any recollection, were heightened to an incredible degree by the Black Death [60] , which spread boundless devastation and misery over Italy. ”

“ Should it be the destiny of mankind to be again visited by the disease of the sixteenth century, (and it is by no means impossible that at some time or other similar events may recur,) we would recommend our posterity to bear in mind this eternal truth, and to treasure up the golden words of the Wittenberg pamphlet, namely, to guard the healing art from strange and unnatural farragos, for it is only when it is subordinate to nature that it bears the stamp of reason—the mistress of all earthly things. ”

“ Were it in any degree within the power of human research to draw up, in a vivid and connected form, an historical sketch of such mighty events, after the manner of the historians of wars and battles, and the migrations of nations, we might then arrive at clear views with respect to the mental development of the human race, and the ways of Providence would be more plainly discernible. It would then be demonstrable, that the mind of nations is deeply affected by the destructive conflict of the powers of nature, and that great disasters lead to striking changes in general civilization. ”

“ They vainly thought to comprehend the whole in the individual, and perceived not the universal spirit which, in intimate union with the mighty powers of nature, animates the movements of all existence, and permits not any phenomenon to originate from isolated causes. To attempt, five centuries after that age of desolation, to point out the causes of a cosmical commotion, which has never recurred to an equal extent,—to indicate scientifically the influences which called forth so terrific a poison in the bodies of men and animals, exceeds the limits of human understanding. ”

“ Now, every species of enthusiasm, every strong affection, every violent passion, may lead to convulsions—to mental disorders—to a concussion of the nerves, from the sensorium to the very finest extremities of the spinal chord. The whole world is full of examples of this afflicting state of turmoil, which, when the mind is carried away by the force of a sensual impression that destroys its freedom, is irresistibly propagated by imitation. ”

“ Small is the number of those who have traversed it; often have they arrested their steps, filled with admiration at striking phenomena; have beheld inexhaustible mines waiting only for the hand of the labourer, and, from contemplating the development of collective organic life, which science nowhere else displays to them on so magnificent a scale, have experienced all the sacred joy of the naturalist to whom a higher source of knowledge has been opened. ”

“ The nature of the first plague in China is unknown. We have no certain intelligence of the disease, until it entered the western countries of Asia. Here it shewed itself as the oriental plague with inflammation of the lungs; in which form it probably also may have begun in China, that is to say, as a malady which spreads, more than any other, by contagion—a contagion, that, in ordinary pestilences, requires immediate contact, and only under unfavourable circumstances of rare occurrence is communicated by the mere approach to the sick. ”

“ By annihilations they awaken new life; and when the tumult above and below the earth is past, nature is renovated, and the mind awakens from torpor and depression to the consciousness of an intellectual existence. ”

“ Now some might suppose, that in the condition of the sciences of the 14th century, no intelligent physicians existed; but this is altogether at variance with the laws of human advancement, and is contradicted by history. The real knowledge of an age is shewn only in the archives of its literature. Here alone the genius of truth speaks audibly:—here alone men of talent deposit the results of their experience and reflection, without vanity or a selfish object. There is no ground for believing that, in the 14th century, men of this kind were publicly questioned regarding their views ”

“ A learned and active physician is certainly one of the noblest of the diversified forms of humanity; for he unites in himself the power arising from an insight into the works of nature, with the exercise of a pure philanthropy inseparable from his office. Few men, however, of this ideal perfection lived in those times, and their mitigating influence over the violence of the epidemic, which was generally past before they could closely examine their new enemy and give any deliberate advice, was doubtless but very inconsiderable. ”

“ The powers of creation come into violent collision; the sultry dryness of the atmosphere; the subterraneous thunders; the mist of overflowing waters, are the harbingers of destruction. Nature is not satisfied with the ordinary alternations of life and death, and the destroying angel waves over man and beast his flaming sword. ”

“ It could not but happen that, in the religious struggles which took place in these years, especial importance would be attributed to the English pestilence. Epidemics readily appear to man, in the narrow circle of his view, as scourges of God; and, indeed, this representation of them has ever been the prevailing one in all religions. For it is easier to estimate the ever-existing sins of humanity than the grand commotions comprehending both mind and body, of a terrestrial organism, which can only be perceived by a superior insight into things ”

“ None of the Universities of Germany, whose business it ought to be to provide, in this respect, for the prosperity of the inheritance committed to their charge, can boast a Professor’s chair for the History of Medicine; nay, in many, it is so entirely unknown, that it is not even regarded as an object of secondary importance, so that it is to be apprehended that the fame of German erudition, may, at least in medicine, gradually vanish, and our medical knowledge become, as practical indeed, but at the same time as assuming, as mechanical, and as defective, as that of France and England. ”

“ The sufferers were, as in the sixteenth century, literally stewed to death! for the moment the people imagined that they knew how nature meant to escape, they ordered feather-beds to be heaped on the perspiring patient, so that the mouth and nose alone remained uncovered. Doors and windows were tightly closed, and the stove emitted a glowing heat, whilst a most intolerable odour of perspiration streamed forth from beneath the broad and lofty beds; added to which, that two and even more patients were often lying in the same room ”

“ They are known only to silent eye-witnesses, and soon fall into oblivion. But hypocrisy, illusion and bigotry, stalk abroad undaunted; they desecrate what is noble, they pervert what is divine, to the unholy purposes of selfishness; which hurries along every good feeling in the false excitement of the age. Thus it was in the years of this plague. ”

“ History—that mirror of human life in all its bearings, offers, even for general pestilences, an inexhaustible, though scarcely explored, mine of facts; here too it asserts its dignity, as the philosophy of reality delighting in truth. ”

“ By so much the more busy were the ignorant and covetous, who, from time immemorial, the more numerous body in the profession, have always injured it in its moral dignity. They attacked the disease with bold assertions, alarmed the people with inconsiderate representations, lauded the infallibility of their remedies, and were the promulgators of injurious prejudices. ”

“ The true ground of the neglect of public protection against pestilential diseases, lay in the general notion and constitution of human society,—it lay in the disregard of human life, of which the great nations of antiquity have given proofs in every page of their history. Let it not be supposed that they wanted knowledge respecting the propagation of contagious diseases. On the contrary, they were as well informed on this subject as the moderns; but this was shewn where individual property, not where human life, on the grand scale, was to be protected. ”

“ Their disease received from it, as it had at other times from other extraordinary customs, a peculiar direction; so that whether bitten by the tarantula or not, they felt compelled to participate in the dances of those affected, and to make their appearance at this popular festival, where they had an opportunity of triumphantly exhibiting their sufferings. Let us here pause to consider the kind of life which the women in Italy led. Lonely, and deprived by cruel custom of social intercourse, that fairest of all enjoyments, they dragged on a miserable existence. ”

“ This disease was a consequence of violent commotions in the earth’s organism—if any disease of cosmical origin can be so considered. One spring set a thousand others in motion for the annihilation of living beings, transient or permanent, of mediate or immediate effect. The most powerful of all was contagion; for in the most distant countries which had scarcely yet heard the echo of the first concussion, the people fell a sacrifice to organic poison,—the untimely offspring of vital energies thrown into violent commotion. ”

“ The state, which founds its legislation on a knowledge of realities, which expects from the physical sciences information respecting human life collectively, considered in all its relations, has a right to demand from its physicians a general insight into the nature and causes of popular diseases. Such an insight, however, as is worthy the dignity of a science, cannot be obtained by the observation of isolated epidemics, because nature never in any one of them displays herself in all her bearings, nor brings into action, at one time, more than a few of the laws of general disease. ”

“ We are of opinion, that the constellations, with the aid of Nature, strive, by virtue of their divine might, to protect and heal the human race; and to this end, in union with the rays of the sun, acting through the power of fire, endeavour to break through the mist. ”

“ The new doctrine took root in towns and villages, but nevertheless the most mortal party hatred raged on all sides, and as usually happens in times of such empassioned commotion, selfishness was the animating spirit which ruled on both sides, and seized the torch of faith, in order, for her unholy purposes, to envelop the world in fire and flames. ”

“ Thus it appears that the age was so little favourable to freedom of thought, that even the most decided sceptics, incapable of guarding themselves against the recollection of what had been presented to the eye, were subdued by a poison, the powers of which they had ridiculed, and which was in itself inert in its effect. ”

“ France, where, under the fearful reign of Louis XI., oppression and misery seemed to mock the gifts of heaven, became in 1482, after a two 189years’ scarcity, the scene of a devastating plague. It was an inflammatory fever with delirium, accompanied by such intense pain in the head, that many dashed out their brains against the wall, or rushed into the water; while others, after incessantly running to and fro, died in a state of the greatest agony. ”

“ I would not, however, be understood to maintain that, during the three epidemics with which, up to the present stage of our inquiry, we have become acquainted, the spread of the sweating fever alone was occasioned by infection; for if the general epidemic causes were powerful enough to excite the disease, without any previously existing poison, why might they not produce the same effect still more independently throughout the course of the pestilence, since, as is the case in all epidemics, those causes in all probability continued to increase in intensity? ”
