Philosophical Letters: or, modest Reflections upon some Opinions in Natural Philosophy
Part 20
I cannot in reason give my consent to your _Authors_ opinion,[1] That _Fishes do by the force or vertue of an inbred Seed transchange simple water into fat, bones, and their own flesh, and that materially they are nothing but water transchanged, and that they return into water by art._ For though my opinion is, that bodies change and alter from one figure into another, yet they do not all change into water, neither is water changed into all other figures; and certainly Fishes do not live nor subsist meerly by Water, but by several other meats, as other animals do; either by feeding upon other Fishes, the stronger devouring the weaker, or upon Mud, and Grass, and Weeds, in the bottom of Seas, Rivers and Ponds, and the like: As for example, put Fish into a Pool or Sluce, wherein there is not any thing but clear, pure water, and in a short time they will be starved to death for want of Food; and as they cannot live onely by water, so neither can they breed by the power of water, but by the power of their food, as a more solid substance: And if all Creatures be nourished by those things whereof they consist, then Fishes do not consist of water, being not nourished by water; for it is not the transchanging of water, by which Fishes live, and by which they produce; but it is the transchange of food, proceeding from other Creatures, as I mentioned above. 'Tis true, Water is a proper element for them to live in, but not to live on; and though I have neither learning, nor experience in _Chymistry_, yet I believe, that your _Author_, with all the subtilest Art he had, could not turn or convert all Creatures into pure and simple water, but there would have been dregs and several mixtures left: I will not say, that the Furnace may not rarifie bodies extreamly, but not convert them into such a substance or form as Nature can. And although he thinks Gold is made of Water, yet I do not believe he could convert it into Water by the help of Fire; he might make it soluble, fluid and rare, but all things that are supple, soluble, flowing and liquid, are not Water; I am confident no _Gas_ or _Blas_ will, or can transform it, nor no Art whatsoever; what Nature may do, I know not. But since your _Authors_ opinion is, that Air is also a Primigenial Element, and in its nature a substance, Why doth he not make it a Principle of natural bodies, as well as Water? I think it had not been so improper to liken Juices to Water; but to make the onely Principle of the composition and dissolution of all Creatures to be Water, seems to me very improbable. Neither can I admit in reason that the Elements should be called, first, pure, and simple beings; we might as well call all other creatures, first, pure, and simple beings: for although the word Element sounds as much as Principle, yet they are in my reason no more Principles of Nature, then other Creatures are, there being but one Principle in Nature, out of which all things are composed, _viz._ the onely matter, which is a pure and simple corporeal substance; and what Man names impure dregs and filths, these are onely irregular and cross motions of that matter, in respect to the nature of such or such a figure; or such motions as are not agreeable and sympathetical to our Passions, Humors, Appetites, and the like. Concerning the Contrarieties, Differences and Wars in Nature, which your _Author_ denies, I have spoken thereof already, and though he endeavours in a long discourse to prove, that there is no War in nature; yet, in my opinion, it is to little purpose, and it makes but a war in the thoughts of the Reader; I know not what it did in his own. But I observe he appeals often to Divinity to bear him up in Natural Philosophy; but how the Church doth approve his Interpretations of the Scripture, I know not: Wherefore I will not meddle with them, lest I offend the Truth of the Divine Scripture, wherein I desire to submit to the Judgment of the Church, which is much wiser then I, or any single Person can be. However, for all what your _Author_ says, I do nevertheless verily believe, there is a war between Natural motions: For example; between the Regular motions of Health, and the Irregular motions of Sickness; and that things applied do oftentimes give assistance to one side or other, but many times in the conflict, the applied remedies are destroyed, and sometimes they are forced to be Neutrals: Wherefore though the nature of Infinite Matter is simple, and knows of no discord, yet her actions may be cross and opposite: the truth is, Nature could never make such variety, did her actions never oppose each other, but live in a constant Peace and Unity. And thus leaving them to agree, I am confident your _Ladiship_ and I shall never disagree; for as long as my life doth last, I shall always prove,
Madam,
_Your constant Friend,_
_and faithful Servant._

_MADAM,_
Your _Author_ condemns the _Schools_ for saying,[1] That _Air is moist_, or that it may be _converted into Water by pressing it together_; bringing an example of an _Iron Pipe, wherein Air has been pressed together, which afterwards in its driving out has, like a Hand-gun discharged with Gun-powder, sent a bullet thorow a board or plank._ Truly, _Madam_, concerning the moisture of Air, I am against it, but the transchanging of Air into Water I do verily believe, _viz._ that some sorts of Air may be contracted or condensed into Water, and that Water again may be dilated into Air, but not readily, commonly and easily by Art, but onely by Nature. Wherefore your _Authors_ Experiment can serve for no proof; for an artificial trial cannot be an infallible natural demonstration, the actions of Art, and the actions of Nature being for the most part very different, especially in productions and transmutations of natural things: Neither can an alteration of parts, cause an utter destruction of the whole, because when some parts change from their figures, other parts of matter change again into the like figures, by which successive change the continuation of the whole is kept up. Next your _Author_ reproves the Schools for maintaining the opinion, that _Air is hot_; for says he, _Water, Air, and Earth, are cold by Creation, because without Light, Heat, and the partaking of Life._ He might, in my opinion, conclude, as well, that Man is cold by Creation, because a Chameleon, or a Fish is cold, being all of animal kind: But why may not some sorts of Air, Water and Earth be hot, and some be cold, as well as some sorts of Light are hot, and some cold; and so several other Creatures? His Reasons prove nothing: for Light doth not make Heat, nor is it the principle of Heat; and it is no consequence to say, all that is without Light is without Heat, there being many things without Light, which nevertheless are Hot; But to say, Water, Air, and Earth are cold, because they are without heat, is no proof, but a meer begging of the principle; for it is but the same thing, as if I should say, this is no Stone, because it is no Glass. And that Water, Air and Earth, do not partake of Life, must be proved first, for that is not granted as yet, there being, according to my opinion, not one Creature that wants Life in all Nature. Again: your _Author_ is of opinion, That _Water is the first and chief Principle of all Natural things._ But this I can no more believe, then that _Water should never change or degenerate from its essence_: nay, if your _Author_ means, there shall always be Water in Nature, it is another thing; but if he thinks that not any part of water doth or can change or degenerate in its nature, and is the principle and chief producer of all other Creatures; then he makes Water rather a Creator then a Creature; and it seems, that those Gentiles which did worship Water, were of the same opinion, whereas yet he condemns all Pagan opinions and all those that follow them. Moreover, I cannot subscribe to his opinion, That _Gas and Blas from the Stars do make heat_: For heat is made several ways, according to its several sorts; for there is a dry heat, and a moist heat, a burning, melting, and evaporating heat, and many more. But as for _Meteors_, that _they are made by Gas and Blas_, I can say nothing, by reason I am not skilled in Astrology, and the science of the Heavens, Stars, and Planets; wherefore if I did offer to meddle with them, I should rather express my Ignorance, then give your _Ladiship_ any solid reasons; and so I am willing to leave this speculation to others, resting content with that knowledg Nature hath given me without the help of Learning: Which I wholly dedicate and offer to your _Ladiship_, as becomes,
Madam,
_Your faithful Friend_
_and Servant._

_MADAM,_
Having made mention in my last of your _Authors_ opinion, _That Air is in its nature Cold_, I thought it fit to take a stricter view of the temper of Air, and to send you withal my own opinion thereof. First of all, I would fain know, what sort of Air your _Author_ means; for if he thinks there is but one sort of Air, he might as well say, that there is but one sort of Animals, or Vegetables; whereas yet there are not onely different sorts of animal and vegetable kind, but also different particulars in one and the same sort: As for example; what difference is not amongst Horses, as between a Barb, a Turk, a Ginnet, a Courser of _Naples_, a Flanders-horse, a Galloway, an English-horse, and so forth? not onely in their shapes, but also in their natures, tempers and dispositions? The like for Cows, Oxen, Sheep, Goats, Dogs, as also for Fowl and Fish, nay, for Men. And as for Vegetables, What difference is there not between Barly and Wheat, and between _French_-barly, _Pine_-barly, and ordinary Barly; as also our _English_-wheat, _Spanish_-wheat, _Turkish_-wheat, _Indian_-wheat, and the like? What difference is there not amongst Grapes, as the _Malago, Muscadel_, and other Grapes, and so of all the rest of Vegetables? The same may be said of the Elements; for there is as much difference amongst the Elements as amongst other Creatures. And so of Air: for Air in some places, as in the _Indies_, especially about _Brasilia_, is very much different from our air, or from the air that is in other places: Indeed, in every different Climate, you shall find a difference of air, wherefore 'tis impossible to assign a certain temper of heat or cold to air in general. But although my sense and reason inform me, that air in its own nature or essence is neither hot nor cold, yet it may become hot or cold, by hot or cold motions; for the sensitive perceptive motions of Air may pattern out heat or cold; and hence it is, that in Summer, when as heat predominates, the air is hot; and in Winter, when as cold predominates, the air is cold. But, perhaps, you will say, air may be cooled by moving it with a Fan, or such like thing which can make wind; wherefore it follows, that air must needs be naturally cold. I answer, That doth not prove Air to be in its nature cold: for this moving or making of wind may contract or condense the air into cold motions, which may cause a cold wind, like as Ventiducts, where the air running thorow narrow Pipes makes a cold wind. The same may be done with a mans breath; for if he contract his lips close, his breath will be cold, but if he opens his mouth wide, his breath will be warm. Again: you may say, that rain is congealed by the coldness of the air into Snow, Hail and Ice. I answer; Frost, Ice, Snow and Hail, do not proceed from the coldness of the air, but rather the coldness of the air proceeds from them; for Ice, Snow, and Hail, proceed from cold contraction and condensation of a vaporous or watery substance; and, as Frost and Snow cause air to be cold, so Thunder and Lightning cause it to be hot, so long as they last. Thus, _Madam_, though Air may be altered either to heat or cold, yet it is neither hot nor Cold in it self. And this is all for the present that I can say concerning the Temper of Air; I conclude, and rest,
Madam,
_Your constant Friend,_
_and faithful Servant._

_MADAM,_
Having hitherto considered your _Authors_ Elements or Principles of Natural things, you will give me leave to present you now with a short view of his Opinions concerning Wind, Vacuum, Rainbows, Thunder, Lightning, Earth-quakes, and the like; which I will do as briefly as I can, lest I betray my Ignorance; for I confess my self not to be well versed in the knowledg of Meteors, nor in those things which properly belong to the Mathematicks, as in Astrology, Geography, Opticks, and the like. But your _Author_ says, in the first place,[1] That _Natural Wind is nothing but a flowing Air, moved by the Blas of the Stars._ Certainly, _Madam_, if this were so, then, in my judgment, when the Stars blaze, we should have constant Winds, and the more they blaze, the more violent winds there would be: But I have rather observed the contrary, that when the Stars blaze most apparently, we have the calmest weather either in Summer or Winter. Perchance your _Author_ will say, he doth not mean this apparant and visible Blas, but another invisible Blas. I answer; I know not, nor cannot conceive any other Blas in the Stars, except I had seen it in a Vision; neither do I think that Nature her self knows of any other, But your _Author_ doth refer himself upon the Authority of _Hypocrates_, who says, That _not onely the Wind is a blast, but that all Diseases are from blasts; and that there is in us a Spirit stirring up all things by its Blas; which Spirit, by a Microcosmical Analogy, or the proportion of a little World, he compares to the blasts of the world._ As for my particular, _Madam_, I dare say, I could never perceive, by my sense and reason, any such blazing Spirit in me; but I have found by experience, that when my mind and thoughts have been benighted with Melancholy, my Imagination hath been more active and subtil, then when my mind has been clear from dark Melancholy: Also I find that my thoughts and conceptions are as active, if not more, in the night then in the day; and though we may sometimes dream of several Lights, yet I cannot perceive a constant light in us; however Light, Blazes, and all those effects are no more then other effects of Nature are; nor can they have more power on other Creatures, then other Creatures have on them: Neither are they made otherwise then by the corporeal motions of Natural Matter, and are dissolved and transchanged as other Creatures, out of one form or figure into another. Next your _Author_ discoursing[2] whether there be any Vacuum in Nature, doth incline to the affirming party, that there is a Vacuum in the Air; to wit, _There is in the air something, that is less then a body, which fills up the emptinesses or little holes and pores in the air, and which is wholly annihilated by fire; It is actually void of all matter, and is a middle thing between a body and an Incorporeal Spirit, and almost nothing in respect of bodies; for it came from Nothing, and so may easily be reduced to nothing._ All this, _Madam_, surpasses my capacity; for I can in no ways conceive any thing between something and nothing, as to be less then something, and more then nothing; for all that is corporeal in Nature, is to my reason something; that is, some really existent thing; but what is incorporeal in Nature, is nothing; and if there be any absolute vacuum in Nature, as your _Author_ endeavours to prove, then certainly this Vacuum cannot be any thing whatsoever; for a Vacuum is a pure Nothing. But many ingenious and learned men have brought as many arguments and reasons against Vacuum, as others bring for it, and so it is a thing which I leave to them to exercise their brains withal. The like is the opinion which many maintain concerning Place, _viz._ that there is a constant succession of Place and Parts, so that when one part removes, another doth succeed in its place; the truth and manner whereof I was never able to comprehend: for, in my opinion, there can be no place without body, nor no body without place, body and place being all but one thing. But as for the perpetual Creation and annihilation of your _Authors_ Vacuities, give me leave to tell you, _Madam_, that it would be a more laborious work, then to make a new World, or then it was to make this present World; for God made this World in six days, and rested the seventh day; but this is a perpetual making of something out of nothing. Again: concerning Rainbows, your _Author_ says,[3] That _a Rainbow is not a natural effect of a natural Cause, but a divine Mystery in its original; and that it has no matter, but yet is in a place, and has its colours immediately in a place, but in the air mediately, and that it is of the nature of Light._ This is indeed a great mystery to my reason; for I cannot conceive, as I said before, a place without a body, nor how Light and Colours can be bodiless: But as for Rainbows, I have observed, when as water hath been blown up into the air into bubles, that by the reflexion of light on the watery bubles, they have had the like colours of the Rainbow; and I have heard, that there hath been often seen at the rising and setting of the Sun, Clouds of divers colours; Wherefore I cannot be perswaded to believe that a Rainbow should not have a natural cause, and consequently be a natural effect; For that God has made it a sign of the Covenant between him and mortal men, is no proof, that it is not a natural effect; Neither can I believe that it has not been before the Flood, and before it was made a sign by God, as your _Author_ imagines; for though it was no sign before the Flood, yet it may nevertheless have had its being and existence before the Flood. Moreover, as for Thunder and Lightning, your _Authors_ opinion is; _That although they may have concurring natural Causes, yet the mover of them is an Incorporeal Spirit, which is the Devil; who having obtained the Principality of this world, that he may be a certain executer of the judgments of the chief Monarch, and so the Umpire and Commissioner of Lightning and Thunder, stirs up a monstrous and sudden Blas in the Air, yet under Covenanted Conditions; for unless his power were bridled by divine Goodness, he would shake the Earth with one stroke so, as to destroy all mortal men: and thus the cracking noise or voice of Thunder is nothing but a spiritual Blas of the Evil Spirit._ I will not deny, _Madam_, that Thunder and Lightning do argue the Power of the most Glorious God, for so do all the rest of the Creatures; but that this is the onely and immediate cause, which your _Author_ assigns of Thunder and Lightning, I cannot believe; for surely, in my opinion, Thunder and Lightning are as much natural effects as other Creatures in Nature; and are not the Devils Blas, for I think they may be made without the help of the Devil; nay, I believe, he may be as much affraid of Thunder, as those Creatures that live on Earth. But what the causes are, and how Thunder and Lightning are made, I have elsewhere declared more at large, especially in my _Philosophical Opinions._ Again your _Author_ speaking[4] of the _Trembling of the Earth, thinks it is nothing else but the Judgment of God for the sins of Impenitent men._ For my part, _Madam_, I can say little to it, either concerning the divine, or the natural cause of Earthquakes: As for the divine and supernatural Cause, which your _Author_ gives, if it was so, then I wonder much, why God should command Earth-quakes in some parts of the World more frequent then in others. As for example; we here in these parts have very seldom Earthquakes, and those we have, which is hardly one in many ages, are not so furious, as to do much harm; and so in many other places of the World, are as few and as gentle Earth-quakes as here; when as in others, Earth-quakes are very frequent and dreadful: From whence it must needs follow, if Earth-quakes be onely a Judgment from God for the sins of Impenitent Men, and not a natural effect, that then those places, where the Earth is not so apt to tremble, are the habitations of the blessed, and that they, which inhabit those parts that are apt to tremble, are the accursed; when as yet, in those places where Earthquakes are not usual and frequent, or none at all, People are as wicked and impious, if not more, then in those where Earthquakes are common. But the question is, Whether those parts which suffer frequent and terrible Earthquakes, would not be so shaken or have such trembling fits, were they uninhabited by Man, or any other animal Creature? Certainly, in my opinion, they would. But as for the Natural Cause of Earthquakes, you must pardon me, _Madam_, that I cannot knowingly discourse thereof, by reason I am not so well skilled in Geography, as to know the several Soils, Climats, Parts, Regions, or Countries, nor what disposed matter may be within those parts that are subject to frequent Earthquakes: Onely this I may say, that I have observed, that the light of a small Fire or Candle, will dilate it self round about; or rather that the air round about the Fire or Candle, will pattern out both its light and its heat. Also I have observed, That a Man in a raging fit of Madness will have such an unusual strength, as ten strong men shall hardly be able to encounter or bind him, when as, this violent fit being past, a single man, nay a youth, may over-master him: Whence I conclude, that the actions, as the motions of Nature, are very powerful when they use their force, and that the ordinary actions of Nature are not so forcible as necessary; but the extraordinary are more forcible then necessary. Lastly, your _Author_ takes great pains to prove,[5] That _the Sun with his light rules the Day, and the Moon with hers the Night; and that the Moon has her own Native light; and that Bats, Mice, Dormice, Owles, and many others, as also Men, which rise at night, and walk in their sleep, see by the light and power of the Moon; also that Plants are more plentifully nourished by the night._ But lest it might be concluded, that all this is said without any probability of Truth, by reason the Moon doth not every night shine upon the Earth, he makes a difference between the Manner of the Sun's and Moon's enlightning the Earth; to wit, that the Sun strikes his beams in a right line towards the Earth, but the Moon doth not respect the Centre of the World, which is the Earth, in a right line; but her Centre is always excentrical, and she respects the Earth onely by accident, when she is concentrical with the World; And therefore he thinks there is another light under the Earth even at Midnight, whereby many Eyes do see, which owes also its rise to the Moon. This opinion of your _Author_ I leave to be examined by those that have skill in Astronomy, and know both the Light and the Course of the Moon: I will onely say thus much, that when the Moon is concentrical, as he calls it, with the World, as when it is Full and New Moon, she doth not shine onely at night, but also in the day, and therefore she may rule the day as well as the night, and then there will be two lights for the ruling of the day, or at least there will be a strife betwixt the Sun and the Moon, which shall rule. But as for Men walking asleep by the light of the Moon, my opinion is, That blind men may walk as well by the light of the Sun, as sleeping men by the light of the Moon. Neither is it probable, that _the Moon or her Blas doth nourish Plants_; for in a cold Moon-shiny night they will often die; but it is rather the Regular motions in well tempered matter that cause fruitful productions and maturity. And so I repose my Pen, lest it trespass too much upon your Patience, resting,
Madam,
_Your humble and_
_faithful Servant._
