MADAM,
Concerning those parts and chapters of your Authors Works, which treat of Physick; before I begin to examine them, I beg leave of you in this present, to make some reflections first upon his Opinions concerning the Nature of Health and Diseases: As for Health, he is pleased to say,[1] That it consists not in a just Temperature of the body, but in a sound and intire Life; for otherwise, a Temperature of body is as yet in a dead Carcass newly kill'd, where notwithstanding there is now death, but not life, not health: Also he says,[2] That no disease is in a dead carcass. To which I answer, That, in my opinion, Life is in a dead Carcass, as well as in a living Animal, although not such a Life as that Creature had before it became a Carcass, and the Temperature of that Creature is altered with the alteration of its particular life; for the temperature of that particular life, which was before in the Animal, doth not remain in the Carcass, in such a manner as it was when it had the life of such or such an Animal; nevertheless, a dead Carcass hath life, and such a temperature of life, as is proper, and belonging to its own figure: for there are as many different lives, as there be different creatures, and each creature has its particular life and soul, as partaking of sensitive and rational Matter. And if a dead Carcass hath life, and such a temperature of motions as belong to its own life, then there is no question, but these motions may move sometimes irregularly in a dead Carcass as well, as in any other Creature; and since health and diseases are nothing else but the regularity or irregularity of sensitive corporeal Motions, a dead Carcass having Irregular motions, may be said as well to have diseases, as a living body, as they name it, although it is no proper or usual term for other Creatures, but onely for Animals. However, if there were no such thing as a disease (or term it what you will, I will call it Irregularity of sensitive motions) in a dead Carcass, How comes it that the infection of a disease proceeds often from dead Carcasses into living Animals? For, certainly, it is not meerly the odour or stink of a dead body, for then all stinking Carcasses would produce an Infection; wherefore this Infection must necessarily be inherent in the Carcass, and proceed from the Irregularity of its motions. Next I'le ask you, Whether a Consumption be a disease, or not? If it be, then a dead Carcass might be said to have a disease, as well as a living body; and the Ægyptians knew a soveraign remedy against this disease, which would keep a dead Carcass intire and undissolved many ages; but as I said above, a dead Carcass is not that which it was being a living Animal, wherefore their effects cannot be the same, having not the same causes. Next, your Author is pleased to call, with Hippocrates, Nature the onely Physicianess of Diseases. I affirm it; and say moreover, that as she is the onely Physicianess, so she is also the onely Destroyeress and Murtheress of all particular Creatures, and their particular lives; for she dissolves and transforms as well as she frames and creates; and acts according to her pleasure, either for the increase or decrease, augmentation or destruction, sickness or health, life or death of Particular Creatures. But concerning Diseases, your Authors opinion is, That a Disease is as Natural as Health. I answer; 'tis true, Diseases are natural; but if we could find out the art of healing, as well as the art of killing and destroying; and the art of uniting and composing, as well as the art of separating and dividing, it would be very beneficial to man; but this may easier be wished for, then obtained; for Nature being a corporeal substance, has infinite parts, as well as an infinite body; and Art, which is onely the playing action of Nature, and a particular Creature, can easier divide and separate parts, then unite and make parts; for Art cannot match, unite, and joyn parts so as Nature doth; for Nature is not onely dividable and composeable, being a corporeal substance, but she is also full of curiosity and variety, being partly self-moving: and there is great difference between forced actions, and natural actions; for the one sort is regular, the other irregular. But you may say, Irregularities are as natural as Regularities. I grant it; but Nature leaves the irregular part most commonly to her daughter or creature Art, that is, she makes irregularities for varieties sake, but she her self orders the regular part, that is, she is more careful of her regular actions; and thus Nature taking delight in variety suffers irregularities; for otherwise, if there were onely regularities, there could not be so much variety. Again your Author says,[3] That a disease doth not consist but in living bodies. I answer, there is not any body that has not life; for if life is general, then all figures or parts have life; but though all bodies have life, yet all bodies have not diseases; for diseases are but accidental to bodies, and are nothing else but irregular motions in particular Creatures, which may be not onely in Animals, but generally in all Creatures; for there may be Irregularities in all sorts of Creatures, which may cause untimely dissolutions; but yet all dissolutions are not made by irregular motions, for many creatures dissolve regularly, but onely those which are untimely. In the same place your Author mentions, That a Disease consists immediately in Life it self, but not in the dregs and filthinesses, which are erroneous forreigners and strangers to the life. I grant, that a Disease is made by the motions of Life, but not such a life as your Author describes, which doth go out like the snuff of a Candle, or as one of Lucian's Poetical Lights; but by the life of Nature, which cannot go out without the destruction of Infinite Nature: and as the Motions of Nature's life make diseases or irregularities, so they make that which man names dregs and filths; which dregs, filths, sickness, and death, are nothing but changes of corporeal motions, different from those motions or actions that are proper to the health, perfection and consistence of such or such a figure or creature. But, to conclude, there is no such thing as corruption, sickness, or death, properly in Nature, for they are made by natural actions, and are onely varieties in Nature, but not obstructions or destructions of Nature, or annihilations of particular Creatures; and so is that we name Superfluities, which bear onely a relation to a particular Creature, which hath more Motion and Matter then is proper for the nature of its figure. And thus much of this subject for the present, from,
Madam,
Your faithful Friend
