Part 32

I perceive you are desirous to know the cause, _Why a man is more weak at the latter end of a disease then at the beginning, and is a longer time recovering health, then loosing health_; as also _the reason of relapses and intermissions?_ First, as for weakness and strength, my opinion is, they are caused by the regular and irregular motions in several parts, each striving to over-power the other in their conflict; and when a man recovers from a disease, although the regular motions have conquered the irregular, and subdued them to their obedience, yet they are not so quite obedient as they ought, which causes weakness: Neither do the regular motions use so much force in Peace, as in War; for though animate matter cannot lose force, yet it doth not always use force; neither can the parts of Nature act beyond their natural power, but they do act within their natural power; neither do they commonly act to the utmost of their power. And as for Health, why it is sooner lost then recovered; I answer, That it is easier to make disorders then to rectifie them: as for example, in a Common-wealth, the ruines of War are not so suddenly repaired, as made. But concerning Relapses and Intermissions of diseases, Intermissions are like truces or cessations from War for a time; and Relapses are like new stirs or tumults of Rebellion; for Rebels are not so apt to settle in peace as to renew the war upon slight occasions; and if the regular motions of the body be stronger, they reduce them again unto obedience. But diseases are occasioned many several ways; for some are made by a home Rebellion, and others by forreign enemies, and some by natural and regular dissolutions, and their cures are as different; but the chief Magistrates or Governors of the animal body, which are the regular motions of the parts of the body, want most commonly the assistance of forreign Parts, which are Medicines, Diets, and the like; and if there be factions amongst these chief Magistrates, or motions of the parts of the body, then the whole body suffers a ruine. But since there would be no variety in Nature, nor no difference between Natures several parts or Creatures, if her actions were never different, but always agreeing and constant, a war or rebellion in Nature cannot be avoided: But, mistake me not, for I do not mean a war or rebellion in the nature or substance of Matter, but between the several parts of Matter, which are the several Creatures, and their several Motions; for Matter being always one and the same in its nature, has nothing to war withal; and surely it will not quarrel with its own Nature. Next you desire to know, that if Nature be in a Perpetual motion, _Whence comes a duration of some things, and a Tiredness, Weariness, Sluggishness, or Faintness?_ I answer, first, That in some bodies, the Retentive motions are stronger then the dissolving motions; as for example, Gold, and Quicksilver or Mercury; the separating and dissolving motions of Fire have onely power to melt and rarifie them for a time, but cannot alter their nature: so a Hammer, or such like instrument, when used, may beat Gold, and make it thin as a Cobweb, or as dust, but cannot alter its interior nature: But yet this doth not prove it to be either without motion, or to be altogether unalterable, and not subject to any dissolution; but onely that its retentive motions are too strong for the dissolving motions of the Fire, which by force work upon the Gold; and we might as well say, that Sand, or an Earthen Vessel, or Glass, or Stone, or any thing else, is unalterable, and will last eternally, if not disturbed. But some of Natures actions are as industrious to keep their figures, as others are to dissolve, or alter them; and therefore Retentive motions are more strong and active in some figures, then dissolving motions are in others, or producing motions in other Figures. Next, as for Tiredness, or Faintness of motions, there is no such thing as tiredness or faintness in Nature, for Nature cannot be tired, nor grow faint, or sick, nor be pained, nor die, nor be any ways defective; for all this is onely caused through the change and variety of the corporeal motions of Nature, and her several parts; neither do irregular motions prove any defect in Nature, but a prudence in Natures actions, in making varieties and alterations of Figures; for without such motions or actions, there could not be such varieties and alterations in Nature as there are: neither is slackness of some motions a defect, for Nature is too wise to use her utmost force in her ordinary works; and though Nature is infinite, yet it is not necessary she should use an infinite force and power in any particular act. Lastly, you desire my opinion, _Whether there be motion in a dead animal Creature._ To which, I answer: I have declared heretofore, that there is no such thing as death in Nature, but what is commonly named death, is but an alteration or change of corporeal motions, and the death of an animal is nothing else but the dissolving motions of its figure; for when a man is dying, the motions which did formerly work to the consistence of his figure do now work to the dissolution of his figure, and to the production of some other figures, changing and transforming every part thereof; but though the figure of that dead animal is dissolved, yet the parts of that dissolved figure remain still in Nature although they be infinitely changed, and will do so eternally, as long as Nature lasts by the Will of God; for nothing can be lost or annihilated in Nature. And this is all, _Madam_, that I can answer to your questions, wherein, I hope, I have obeyed your commands, according to the duty of,

Madam,

_Your faithful Friend_

_and humble Servant._

_MADAM,_

I have thus far discharged my duty, that according to your commands, I have given you my judgment of the works of those four famous Philosophers of our age, which you did send me to peruse, and have withal made reflexions upon some of their opinions in Natural Philosophy, especially those, wherein I did find them dissent from the Ground and Principles of my own Philosophy. And since by your leave I am now publishing all those Letters which I have hitherto written to you concerning those aforesaid Authors, and their Works, I am confident I shall not escape the censures of their followers; But, I shall desire them, that they will be pleased to do me this Justice, and to examine first my opinions well, without any partiality or wilful misinterpretation of my sence, before they pass their censure: Next, I desire them to consider, That I have no skill in School-learning, and therefore for want of terms of Art may easily chance to slip, or at least, not express my opinions so clearly as my readers expected; However, I have done my endeavour, and to my sense and reason they seem clear and plain enough, especially as I have expressed them in those Letters I have sent you; for concerning my other Work, called _Philosophical Opinions_, I must confess, that it might have been done more exactly and perspicuously, had I been better skilled in such words and expressions as are usual in the Schools of Philosophers; and therefore, if I be but capable to learn names and terms of Art, (although I find my self very untoward to learn, and do despair of proving a Scholar) I will yet endeavour to rectifie that work, and make it more intelligible; for my greatest ambition is to express my conceptions so, that my Readers may understand them: For which I would not spare any labour or pains, but be as industrious as those that gain their living by their work; and I pray to God, that Nature may give me a capacity to do it. But as for those that will censure my works out of spite and malice, rather then according to justice, let them do their worst; for if God do but bless them, I need not to fear the power of Nature, much less of a part of Nature, as Man. Nay, if I have but your Ladiships approbation, it will satisfie me; for I know you are so wise and just in your judgment, that I may safely rely upon it: For which I shall constantly and unfeignedly remain as long as I live,

Madam,

_Your Ladiships most faithful Friend_

_and humble Servant._

_MADAM,_

I perceive, you take great delight in the study of Natural Philosophy, since you have not onely sent me some Authors to peruse, and give my judgment of their opinions, but are very studious your self in the reading of Philosophical Works: and truly, I think you cannot spend your time more honourably, profitably, and delightfully, then in the study of Nature, as to consider how Variously, Curiously, and Wisely, she acts in her Creatures; for if the particular knowledg of a mans self be commendable, much more is the knowledg of the general actions of Nature, which doth lead us to the knowledg of our selves. The truth is, by the help of Philosophy our minds are raised above our selves, into the knowledg of the Causes of all natural effects. But leaving the commending of this noble study, you are pleased to desire my opinion of a very difficult and intricate argument in Natural Philosophy, to wit, of Generation, or Natural Production. I must beg leave to tell you, first, that some (though foolishly) believe, it is not fit for Women to argue upon so subtil a Mystery: Next, there have been so many learned and experienced Philosophers, Physicians, and Anatomists, which have treated of this subject, that it might be thought a great presumption for me, to argue with them, having neither the learning nor experience by practice which they had: Lastly, There are so many several ways and manners of Productions in Nature, as it is impossible for a single Creature to know them all: For there are Infinite variations made by self-motion in Infinite Matter, producing several Figures, which are several Creatures in that same Matter. But you would fain know, how Nature, which is Infinite Matter, acts by self-motion? Truly, _Madam_, you may as well ask any one part of your body, how every other part of your body acts, as to ask me, who am but a small part of Infinite Matter, how Nature works. But yet, I cannot say, that Nature is so obscure, as her Creatures are utterly ignorant; for as there are two of the outward sensitive organs in animal bodies, which are more intelligible then the rest, to wit, the Ear, and the Eye; so in Infinite Matter, which is the body of Nature, there are two parts, which are more understanding or knowing then the rest, to wit, the Rational and Sensitive part of Infinite Matter; for though it be true, That Nature, by self-division, made by self-motion into self-figures, which are self-parts, causes a self-obscurity to each part, motion, and figure; nevertheless, Nature being infinitely wise and knowing, its infinite natural wisdom and knowledg is divided amongst those infinite parts of the infinite body: and the two most intelligible parts, as I said, are the sensitive and rational parts in Nature, which are divided, being infinite, into every Figure or Creature; I cannot say equally divided, no more, then I can say, all creatures are of equal shapes, sizes, properties, strengths, quantities, qualities, constitutions, semblances, appetites, passions, capacities, forms, natures, and the like; for Nature delights in variety, as humane sense and reason may well perceive: for seldom any two creatures are just alike, although of one kind or sort, but every creature doth vary more or less. Wherefore it is not probable, that the production or generation of all or most Creatures, should be after one and the same manner or way, for else all Creatures would be just alike without any difference. But this is to be observed, that though Nature delights in variety, yet she doth not delight in confusion, but, as it is the propriety of Nature to work variously, so she works also wisely; which is the reason, that the rational and sensitive parts of Nature, which are the designing and architectonical parts, keep the species of every kind of Creatures by the way of Translation in Generation, or natural Production; for whatsoever is transferred, works according to the nature of that figure or figures from whence it was transferred, But mistake me not; for I do not mean always according to their exterior Figure, but according to their interior Nature; for different motions in one and the same parts of matter, make different figures, wherefore much more in several parts of matter and changes of motion; But, as I said, Translation is the chief means to keep or maintain the species of every kind of Creatures, which Translation in natural production or generation, is of the purest and subtilest substances, to wit, the sensitive and rational, which are the designing and architectonical parts of Nature. You may ask me, _Madam_, what this wise and ingenious Matter is. I answer: It is so pure, subtil, and self-active, as our humane shares of sense and reason cannot readily or perfectly perceive it; for by that little part of knowledg that a humane creature hath, it may more readily perceive the strong action then the purer substance; for the strongest action of the purest substance is more perceivable then the matter or substance it self; which is the cause, that most men are apt to believe the motion, and to deny the matter, by reason of its subtilty; for surely the sensitive and rational matter is so pure and subtil, as not to be expressed by humane sense and reason. As for the rational matter, it is so pure, fine, and subtil, that it may be as far beyond lucent matter, as lucent matter is beyond gross vapours, or thick clouds; and the sensitive matter seems not much less pure: also there is very pure inanimate matter, but not subtil and active of it self; for as there are degrees in the animate, so there are also degrees in the inanimate matter; so that the purest degree of inanimate matter comes next to the animate, not in motion, but in the purity of its own degree; for it cannot change its nature so, as to become animate, yet it may be so pure in its own nature, as not to be perceptible by our grosser senses. But concerning the two degrees of animate Matter, to wit, the sensitive and rational, I say that the sensitive is much more acute then Vitriol, Aqua-fortis, Fire, or the like; and the rational much more subtil and active then Quicksilver, or Light, so as I cannot find a comparison fit to express them, onely that this sensitive and rational self-moving Matter is the life and soul of Nature; But by reason this Matter is not subject to our gross senses, although our senses are subject to it, as being made, subsisting and acting through the power of its actions, we are not apt to believe it, no more then a simple Country-wench will believe, that Air is a substance, if she neither hear, see, smell, taste, or touch it, although Air touches and surrounds her: But yet the effects of this animate matter prove that there is such a matter; onely, as I said before, this self-moving matter causing a self-division as well as a general action, is the cause of a self-obscurity, which obscurity causes doubts, disputes, and inconstancies in humane opinions, although not so much obscurity, as to make all Creatures blind-fold, for surely there is no Creature but perceives more or less. But to conclude, The Rational degree of Matter is the most intelligible, and the wisest part of Nature, and the Sensitive is the most laborious and provident part in Nature, both which are the Creators of all Creatures in Infinite Matter; and if you intend to know more of this Rational and Sensitive Matter, you may consult my Book of Philosophy, to which I refer you. And so taking my leave for the present, I rest,

Madam,

_Your Faithful Friend_

_and Servant._

II.

_MADAM,_

I understand by your last, that you have read the Book of that most learned and famous Physician and Anatomist, Dr. _Harvey_, which treats of Generation; and in the reading of it, you have mark'd several scruples, which you have framed into several questions concerning that subject, to which you desire my answer. Truly, _Madam_, I am loth to imbarque my self in this difficult argument, not onely for the reasons I have given you heretofore, but also that I do not find my self able enough to give you such a satisfactory answer as perhaps you do expect. But since your Commands are so powerful with me, that I can hardly resist them, and your Nature so good that you easily pardon any thing that is amiss, I will venture upon it according to the strength of my Natural Reason, and endeavour to give you my opinion as well and as clearly as I can. Your first question is; _Whether the action of one or more producers be the onely cause of Natural Production or Generation, without imparting or transferring any of their own substance or Matter._ I answer: The sole co-action of the Producers may make a change of exterior forms or figures, but not produce another Creature; for if there were not substance or matter, as well as action, both transferred together, there would not be new Creatures made out of old Matter, but every production would require new Matter, which is impossible, if there be but one Matter, and that infinite; and certainly, humane sense and reason may well perceive, that there can be but one Matter, for several kinds of Matter would make a confusion; and thus if new Creatures were made onely by substanceless motion, it would not onely be an infinite trouble to Nature, to create something out of nothing perpetually, but, as I said, it would make a confusion amongst all Nature's works, which are her several Parts or Creatures. But by reason there is but one Matter, which is Infinite and Eternal, and this Matter has self-motion in it, both Matter and Motion must of necessity transmigrate, or be transferred together without any separation, as being but one thing, to wit, Corporeal Motion. 'Tis true, one part of animate or self-moving Matter, may without Translation move, or rather occasion other parts to move; but one Creature cannot naturally produce another without the transferring of its corporeal motions. But it is well to be observed, that there is great difference between the actions of Nature; for all actions are not generating, but some are patterning, and some transforming, and the like; and as for the transforming action, that may be without translation, as being nothing else but a change of motions in one and the same part or parts of Matter, to wit, when the same parts of Matter do change into several figures, and return into the same figures again. Also the action of Patterning is without Translation; for to pattern out, is nothing else but to imitate, and to make a figure in its own substance or parts of Matter like another figure. But in generation every producer doth transfer both Matter and Motion, that is, Corporeal Motion into the produced; and if there be more producers then one, they all do contribute to the produced; and if one Creature produces many Creatures, those many Creatures do partake more or less of their producer. But you may say, If the producer transfers its own Matter, or rather its own corporeal motions into the produced, many productions will soon dissolve the producer, and he will become a sacrifice to his off-spring. I answer; That doth not follow: for as one or more Creatures contribute to one or more other Creatures, so other Creatures do contribute to them, although not after one and the same manner or way, but after divers manners or ways; but all manners and ways must be by translation to repair and assist; for no Creature can subsist alone and of it self, but all Creatures traffick and commerce from and to each other, and must of necessity do so, since they are all parts of the same Matter: Neither can Motion subsist without Matter, nor quit Matter, nor act without Matter, no more, then an Artificer can work without materials, and without self-motion Matter would be dead and useless; Wherefore Matter and Motion must upon necessity not onely be inseparable, but be one body, to wit, corporeal motion; which motion by dividing and composing its several parts, and acting variously, is the cause of all Production, Generation, Metamorphosing, or any other thing that is done in Nature. But if, according to your _Author_, the sole action be the cause of Generation without transferring of substance, then Matter is useless, and of none or little effect; which, in my opinion, is not probable.

Your second question is, _Whether the Production or Generation of animals is as the Conceptions of the Brain, which the Learned say are Immaterial?_ I answer: The Conceptions of the Brain, in my opinion, are not Immaterial, but Corporeal; for though the corporeal motions of the brain, or the matter of its conceptions, is invisible to humane Creatures, and that when the brain is dissected, there is no such matter found, yet that doth not prove, that there is no Matter, because it is not so gross a substance as to be perceptible by our exterior senses: Neither will your _Authors_ example hold, that as a builder erects a house according to his conception in the brain, the same happens in all other natural productions or generations; for, in my opinion, the house is materially made in the brain, which is the conception of the builder, although not of such gross materials, as Stone, Brick, Wood, and the like, yet of such matter as is the Rational Matter, that is, the house when it is conceived in the brain, is made by the rational corporeal figurative motions of their own substance or degree of Matter; But if all Animals should be produced by meer fancies, and a Man and a Woman should beget by fancying themselves together in copulation, then the produced would be a true Platonick Child; But if a Woman being from her Husband should be so got with Child, the question is, whether the Husband would own the Child; and if amorous Lovers (which are more contagious for appetite and fancy then Married persons) should produce Children by Immaterial contagions, there would be more Children then Parents to own them.

Your third question is, _Whether Animals may not be produced, as many Diseases are, by contagion?_ I answer: Although contagions may be made at a distance, by perception; yet those diseases are not begotten by immaterial motions, but by the rational and sensitive corporeal motions, which work such diseases in the body of a Creature, by the association of parts, like as the same disease is made in another body: Neither are diseases always produced after one and the same manner, but after divers manners; whereas animals are produced as animals, that is, after one natural and proper way; for although all the effects in particular be not alike, yet the general way or manner to produce those effects is the same: As for example; there is no other way to produce a fruitful Egg, but by a Cock and a Hen; But a Contagious disease, as the small-Pox, or the like, may be produced by the way of Surfeits or by Conceit, which may cause the sensitive corporeal parts, through the irregular motions of the rational corporeal parts, to work and produce such a disease, or any other ways. But neither a disease, nor no creature else can be produced without matter, by substanceless motion; for wheresoever is motion, there is also matter, matter and motion being but one thing.
