XLI.

_MADAM,_

Your _Author_ speaking of the _Gout_, and of that kind of Gout which

is called _Hereditary_, says, _It consists immediately in the Spirit

of Life._ First, as for that which is called an Hereditary Disease,

propagated from Parents upon their Children; my opinion is, That it

is nothing else but the same actions of the animate matter, producing

the same effect in the Child as they did in the Parent: For example;

the same motions which made the Gout in the Parent, may make the same

disease in the Child; but every Child has not his Parents diseases, and

many Children have such diseases as their Parents never had; neither is

any disease tied to a particular Family by Generation, but they proceed

from irregular motions, and are generally in all Mankind; and therefore

properly there is no such thing as an hereditary propagation of

diseases; for one and the same kind of disease may be made in different

persons, never a kin to one another, by the like motions; but because

Children have such a neer relation to their Parents by Generation, if

they chance to have the same diseases with their Parents, men are apt

to conclude it comes by inheritance; but we may as well say, that all

diseases are hereditary; for there is not any disease in Nature but is

produced by the actions of Nature's substance; and if we receive life

and all our bodily substance by Generation from our Parents, we may be

said to receive diseases too; for diseases are inherent in the matter

or substance of Nature, which every Creature is a part of, and are real

beings made by the corporeal motions of the animate matter, although

irregular to us; for as this matter moves, so is Life or Death,

Sickness or Health, and all natural effects; and we consisting of the

same natural matter, are naturally subject as well to diseases as to

health, according as the Matter moves. Thus all diseases are hereditary

in Nature; nay, the Scripture it self confirms it, informing us, that

diseases, as well as death, are by an hereditary propagation derived

from _Adam_ upon all Posterity. But as for the Gout, your _Authors_

doctrine is,[1] _That Life is not a body, nor proper to a body, nor the

off-spring of corporeal Proprieties_,[2] but a _meer No-thing_; and

that _the Spirit of Life is a real being, to wit, the arterial blood

resolved by the Ferment of the heart into salt air, and enlightned by

life_,[3] and that the Gout doth immediately consist in this spirit of

life. All which how it doth agree, I cannot conceive; for that a real

being should be enlightned by Nothing, and be a spirit of Nothing, is

not imaginable, nor how the Gout should inhabit in the spirit of life;

for then it would follow, that a Child, as soon as it is brought forth

into the world, would be troubled with the Gout, if it be as natural

to him as life, or have its habitation in the Spirit of Life. Also

your _Author_ is speaking of _an Appoplexy in the head, which takes

away all sense and motion._ But surely, in my opinion, it is impossible

that all sense and motion should be out of the head; onely that sense

and motion, which is proper to the head, and to the nature of that

Creature, is altered to some other sensitive and rational motions,

which are proper to some other figure; for there is no part or particle

of matter that has not motion and sense. I pray consider, _Madam_,

is there any thing in Nature that is without motion? Perchance you

will say, Minerals; but that is proved otherwise; as for example, by

the sympathetical motion between the Loadstone and Iron, and between

the Needle and the North, as also by the operation of Mercury, and

several others; Wherefore there is no doubt, but all kinds, sorts and

particulars of Creatures have their natural motions, although they are

not all visible to us, but not such motions as are made by Gas, or

Blas, or Ideas, &c. but corporeal sensitive and rational motions, which

are the actions of Natural Matter. You may say, Some are of opinion,

that Sympathy and Antipathy are not Corporeal motions. Truly, whosoever

says so, speaks no reason; for Sympathy and Antipathy are nothing else

but the actions of bodies, and are made in bodies; the Sympathy betwixt

Iron and the Loadstone is in bodies; the Sympathy between the Needle

and the North is in bodies; the Sympathy of the Magnetic powder is in

bodies. The truth is, there is no motion without a body, nor no body

without motion. Neither doth Sympathy and Antipathy work at distance

by the power of Immaterial Spirits, or rays, issuing out of their

bodies, but by agreeable or disagreeable corporeal motions; for if

the motions be agreeable, there is Sympathy; if disagreeable, there

is Antipathy; and if they be equally found in two bodies, then there

is a mutual Sympathy or Antipathy; but if in one body onely, and not

in the other, there is but Sympathy or Antipathy on one side, or in

one Creature. Lastly, concerning _swoonings or fainting fits_, your

_Authors_ opinion is, that they _proceed from the stomack_: Which I

can hardly believe; for many will swoon upon the sight of some object,

others at a sound, or report, others at the smell of some disagreeable

odour, others at the taste of some or other thing that is not agreeable

to their nature, and so forth: also some will swoon at the apprehension

or conceit of something, and some by a disorder or irregularity of

motions in exterior parts. Wherefore, my opinion is, that swoonings

may proceed from any part of the body, and not onely from the stomack.

But, _Madam_, I being no Physicianess may perhaps be in an error,

and therefore I will leave this discourse to those that are thorowly

learned and practised in this Art, and rest satisfied that I am,

Madam,
