Overview
The Generality of Men, have for a long time had too Narrow Thoughts of Physick, as if it were in a manner Confin’d to little more than Internals, without allowing themselves the Liberty of common Reasoning, by which they easily might have found that the Humane Body is liable to, and requires several Administrations of a very Different Nature, and that it is very unreasonable to suppose, that since there are so many ways for Diseases to enter upon us, there should be so few for Health to return by. Internals do indeed make up the far greatest part of the Means of Cure, but yet there are Considerable Cases, where the very Nature of the thing requires other Methods; and this would appear very obvious, if it were not for our too Partial Consideration of the Body of Man, by attributing too much to the Fluids, and too little to the Solids, both which, tho’ they have a Mutual Dependance upon one another, yet have each of ’em some Proprieties, and if out of Order, require something particular in the Application to restore ’em again. Consent in the Solids, answers to Mixture in the Fluids; and as an ill Ferment, as soon as it comes into the Blood, diffuses and mixes it self with the whole Mass, and cannot often be extirpated, till the Medicine given for that end, has been taken so long as to be diffus’d and intimately mix’d with the Blood likewise; so a Violent Seizure in one of the Solid Parts, commonly draws all the rest into Consent, and a particular Application to the Place primarily affected shall do no good, when a Universal one shall Cure; and a thing which would be trivial and Vain, if us’d as a Topick, shall by a Universal Administration prove of the greatest Importance. We see Contraries often prove Remedies to one another in the Juices, and Poisons become Beneficial, when oppos’d to certain Humours, why should we not then allow of the same Rule, in the Containing Parts of the Body? If by a Supine Course of Life, the Nervous parts are weakned and relax’d, why should we not suppose the contrary way of Living, the most likely to repair ’em? Since the Vigour of those parts is acquir’d by Use; they are the Active part of the Man, and not always liable to the Impressions of the Fluids, for tho’ you invigorate the Blood ever so much by the most generous Medicines, the Nerves may remain Effete and Languid notwithstanding; but if the Nervous parts are extended and exercis’d, the Blood and the Humours must necessarily partake of the Benefit, and soon discover it by the Increase of their Heat and Motion. There is so much of a Relative Nature in every thing, that can concern the Health or Distemperature of the Individual, that there is scarce any thing so prejudicial, or seemingly Absurd, but may in different Circumstances prove as Advantageous. The World has lately had full Evidence of the good Effects of an Intense Cold, equally apply’d to all the Parts of the Body at once, which Method of Curing would, not many Years agoe, have been thought very Extravagant, and certainly Destructive. On the contrary, there are other Cases, where a Warm Bath is only prevalent; and though some People have suppos’d it to be only a kind of a last Resort, when other things have been try’d in Vain, yet it is quite otherwise, it being impossible to remove some Diseases of the Limbs, without an universal equal Relaxation. Again, quite different from this is the equal Distribution of a greater Degree of Heat throughout the whole Body, which is procur’d by Habitual Exercise; in the former Method, the Parts are relax’d, in this they are strengthned, and in every Respect the Effects are widely different, tho’ in both ways there is a considerable Encrease of Heat.
