empty space in the Vial before it was sucked And then why does not the water rise to fill that when a man sucks the Vial he draws nothing out neither into his Belly nor into his Lungs nor into his Mouth only he sets the Air within the glass into a circular motion giving it at once an endeavour to go forth by the sucking and an endeavour to go back by not receiving it into his mouth And so with a great deal of labour glues his lips to the neck of the Vial. Then taking it off and dipping the neck of the Vial into the water before the circulation cease the Air with the endeavour it hath now gotten pierces the water and goes out And so much Air as goes out so much matter comes up into the room of it CHAP. IIII. Problems of Heat and Light A. WHat is the cause of Heat B. How know you that any thing is Hot but your self A. Because I perceive by sense it Heats me B. It is no good argument The thing Heats me therefore it is Hot. But what alteration do you find in your body at any time by being Hot A. I find my skin more extended in Summer than in Winter and am sometimes fainter and weaker then ordinary as if my Spirits were exhaled and I sweat B. Then that is it you would know the cause of I have told you before that by the motion I suppose both in the Sun and in the Earth the Air is dissipated and consequently that there would be an infinite number of small empty places but that the World being full there comes from the next parts other Air into the spaces they would else make empty When therefore this motion of the Sun is excercised upon the Superficies of the Earth if there do not come out of the Earth it self some corporal substance to supply that tearing of the Air we must return again to the admission of Vacuum If there do then you see how by this motion fluid bodies are made to exhale out of the Earth The like happens to a mans body or hand which when he perceives he says he is Hot. And so of the Earth when it sendeth forth Water and Earth together in Plants we say it does it by Heat from the Sun A. 'T is very probable and no less probable that the same action of the Sun is that which from the Sea and moist places of the Earth but especially from the Sea fetcheth up the water into the Clouds But there be many ways of Heating besides the action of the Sun or of Fire Two pieces of Wood will take Fire if in Torning they be prest together B. Here again you have a manifest laceration of the Air by the reciprocal and contrary motions of the two pieces of wood which necessarily causeth a coming forth of whatsoever is Aereal or fluid within them and the motion pursued a dissipation also of the other more solid parts into Ashes A. How comes it to pass that a man is warmed even to sweating almost with every extraordinary labour of his body B. It is easie to understand how by that labour all that is liquid in his body is tossed up and down and thereby part of it also cast forth A. There be some things that make a man Hot without sweat or other evaporation as Caustiques Nettles and other things B. No doubt But they touch the part they so Heat and cannot work that effect at any distance A. How does Heat cause light and that partially in some bodies more in some less though the Heat be equal B. Heat does not cause Light at all But in many Bodies the same cause that is to say the same motion causeth both together so that they are not to one another as cause and effect but are concomitant Effects sometimes of one and the same motion A. How B. You know the rubbing or heard pressing of the Eye or a stroke upon it makes an apparition of Light without and before it which way soever you look This can proceed from nothing else but from the restitution of the Organ pressed or stricken unto its former ordinary situation of parts Does not the Sun by his thrusting back the Air upon your eyes press them Or does not those bodies whereon the Sun shines though by reflection do the same though not so strongly And do not the Organs of Sight the Eye the Heart and Brains resist that pressure by an endeavour of restitution outwards Why then should there not be without and before the Eye an apparition of Light in this case as well as in the other A. I grant there must But what is that which appears after the pressing of the eye For there is nothing without that was not there before or if there were methinks another should see it better or as well as he or if in the dark methinks it should enlighten the place B. It is a fancy such as is the appearance of your face in a Looking-glass such as is a Dream such as is a Ghost such as is a spot before the Eye that hath stared upon the Son or Fire For all these are of the Regiment of Fancy without any body concealed under them or behind them by which they are produced A. And when you look towards the Sun or Moon why is not that also which appears before your Eyes at that time a fancy B. So it is Though the Sun it self be a real Body yet that bright Circle of about a foot Diameter cannot be the Sun unless there be two Suns a greater and a lesser And because you may see that which you call the Sun both above you in the Skie and before you in the Water and two Suns by distorting your Eye in two places of the Skie one of them must needs be Fancy And if one both All sense is Fancy though the cause be always in a real Body A. I see by this that those things which the Learned call the Accidents of Bodies are indeed nothing else but diversity of Fancy and are inherent in the Sentient and not in the Objects except Motion and Quantity And I perceive by your Doctrine you have been tampering with Leviathan But how comes Wood with a certain degree of Heat to shine and Iron also with a greater degree but no Heat at all to be able to make water shine B. That which shineth hath the same Motion in its parts that I have all this while supposed in the Sun and Earth In which Motion there must needs be a competent degree of swiftness to move the sense that is to make it visible All Bodies that are not fluid will shine with Heat if the Heat be very great Iron will shine and Gold will shine but water will not because the parts are carried away before they attain to that degree of swiftness which is requisite A. There are many fluid Bodies whose parts evaporate and yet they make a flame as Oyl and Wine and other

Crooke at the Green-Dragon without Temple-Bar MDCLXXXII THE BOOKSELLER TO THE READER MY Duty as well to the Publick as to the Memory of Mr. Hobbs has obliged me to procure with my utmost diligence that these Tracts should come forth with the most correct exactness I am compell'd by the force of Truth to declare how much both the World and the Name of Mr. Hobbs have been abus'd by the several spurious Editions of the History of the Civil Wars wherein by various and unskilful Transcriptions are committed above a thousand faults and in above a hundred places whole Lines left out as I can make appear I must confess Mr. Hobbs upon some considerations was averse to the publishing thereof but since it is impossible to suppress it no Book being more commonly sold by all Booksellers I hope I need not fear the Offence of any Man by doing Right to the World and this Work Which I now Publish from the Original Manuscript done by his own Amanuensis and given me by himself above twelve years since To this I have joyn'd the Treatise against Arch-Bishop Bramhall to prevent the like prejudice which must certainly have faln on it there being so many false Copies abroad if not thus prevented as also the Discourse of Heresie from a more correct Copy and have likewise annex'd his Physical Problems as they were translated by himself and presented to His Majesty with the Epistle prefix'd in the Year 1662. at the same time they came forth in Latin These things premis'd there remains nothing but to wish for my self good sale to the Buyer much pleasure and satisfaction Your Humble Servant William Crooke Behemoth OR THE EPITOME OF THE Civil Wars OF ENGLAND PART I. A. IF in time as in place there were degrees of high and low I verily believe that the highest of time would be that which passed between 1640. and 1660. for he that thence as from the Devils Mountain should have looked upon the World and observ'd the Actions of Men especially in England might have had a Prospect of all kinds of Injustice and of all kinds of Folly that the World could afford and how they were produced by their Hypocrisie and self-conceit whereof the one is double Iniquity and the other double Folly B. I should be glad to behold that Prospect You that have liv'd in that time and in that part of your Age wherein Men use to see best into good and evil I pray you set me that could not see so well upon the same Mountain by the Relation of the Actions you then saw and of their Causes Pretensions Justice Order Artifice and Event A. In the Year 1640. the Government of England was Monarchical and the King that reigned Charles the first of that name holding the Sovereignty by right of a descent continued above 600 years and from a much longer descent King of Scotland and from the time of his Ancestors Henry the second King of Ireland a Man that wanted no vertue either of Body or Mind nor endeavour'd any thing more than to discharge his Duty towards God in the well governing of his Subjects B. How could he then miscarry having in every County so many Trained Soldiers as would put together have made an Army of 60000 Men and divers Magazines of Ammunition in places fortified A. If those Soldiers had been as they and all other of his Subjects ought to have been at his Majesties command the Peace and Happiness of the three Kingdoms had continued as it was left by King James but the People were corrupted generally and disobedient persons esteemed the best Patriots B. But sure there were Men enough besides those that were ill-affected to have made an Army sufficient to have kept the People from uniting into a Body able to oppose him A. Truly I think if the King had had Money he might have had Soldiers enough in England for there were very few of the Common People that cared much for either of the Causes but would have taken any side for pay and plunder but the Kings Treasure was very low and his Enemies that pretended the Peoples ease from Taxes and other specious things had the command of the Purses of the City of London and of most Cities and Corporate Towns in England and of many particular persons besides B. But how came the People to be so corrupted and what kind of People were they that did so seduce them A. The Seducers were of divers sorts One sort were Ministers Ministers as they call'd themselves of Christ and sometimes in their Sermons to the People God's Ambassadors pretending to have a right from God to govern every one his Parish and their Assembly the whole Nation Secondly there were a very great number though not comparable to the other which notwithstanding that the Popes power in England both Temporal and Ecclesiastical had been by Act of Parliament abolished did still retain a belief that we ought to be governed by the Pope whom they pretended to be the Vicar of Christ and in the Right of Christ to be the Governour of all Christian People and these were known by the Name of Papists as the Ministers I mentioned before were commonly called Presbyterians Thirdly There were not a few who in the beginning of the Troubles were not discovered but shortly after declared themselves for a Liberty in Religion and those of different Opinions one from another some of them because they would have all Congregations free and independent upon one another were called Independents Others that held Baptism to Infants and such as understood not into what they are baptized to be ineffectual were called therefore Anabaptists Others that held that Christ's Kingdom was at this time to begin upon the Earth were called Fifth-monarchy-men besides divers other Sects as Quakers Adamites c. whose Names and peculiar Doctrines I do not well remember and these were the Enemies which arose against his Majesty from the private Interpretation of the Scripture exposed to every Man 's scanning in his Mother-Tongue Fourthly There were
that they fell in hand with the work so quickly For the first Rector of the University of Paris as I have read somewhere was Peter Lombard who first brought in them the Learning called School-Divinity and was seconded by John Scot of Duns who lived in or near the same time whom any ingenious Reader not knowing what was the Design would judge to have been two the most egregious Blockheads in the World so obscure and senseless are their Writings And from these the School-men that succeeded learnt the trick of imposing what they list upon their Readers and declining the force of true Reason by Verbal Forkes I mean Distinctions that signifie nothing but serve only to astonish the multitude of ignorant Men. As for the understanding Readers they were so few that these new sublime Doctors cared not what they thought These School men were to make good all the Articles of Faith which the Popes from time to time should command to be believ'd amongst which there were very many inconsistent with the Rights of Kings and other Civil Sovereigns as asserting to the Pope all Authority whatsoever they should declare to be necessary in ordine ad spiritualia that is to say in order to Religion From the Universities also it was That all Preachers proceeded and were poured out into City and Country to terrifie the People into an absolute obedience to the Pope's Canons and Commands which for fear of wakening Kings and Princes too much they durst not yet call Laws From the Universities it was That the Philosophy of Aristotle was made an Ingredient to Religion as serving for a Salve to a great many of absurd Articles concerning the Nature of Christ's Body and the Estate of Angels and Saints in Heaven which Articles they thought fit to have believed because they bring some of them profit and others reverence to the Clergy even to the meanest of them for when they shall have made the People believe that the meanest of them can make the Body of Christ who is there that will not both shew them reverence and be liberal to them or to the Church especially in the time of their sickness when they think they make and bring unto them their Saviour B. But what advantage to them in these Impostures was the Doctrine of Aristotle A. They have made more use of his obscurity than of his Doctrine for none of the Ancient Philosophers Writings are comparable to those of Aristotle for their aptness to puzzle and entangle men with words and to breed Disputation which must at last be ended in the Determination of the Church of Rome and yet in the Doctrine of Aristotle they made use of many Points as first the Doctrine of seperated Essences B. What are seperated Essences A. Seperated Beings B. Seperated from what A. From every thing that is B. I cannot understand the Being of any thing which I understand not to be but what can they make of that A. Very much in questions concerning the Nature of God and concerning the Estate of Man's Soul after death in Heaven Hell and Purgatory by which you and every man knows how great obedience and how much Money they gain from the Common People Whereas Aristotle holdeth the Soul of Man to be the first giver of motion to the Body and consequently to it self they make use of that in the Doctrine of Free-will what and how they gain by that I will not say He holdeth forth that there be many things that come to pass in this World from no necessity of Causes but meer Contingency Casualty and Fortune B. Methinks in this they make God stand idle and to be a meer Spectator of the Games of Fortune for what God is the cause of must needs come to pass and in my opinion nothing else But because there must be some ground for the Justice of the Eternal Torment of the damned perhaps it is this that mens Wills and Propensions are not they think in the Hands of God but of themselves and in this also I see somewhat conducing to the Authority of the Church A. This is not much nor was Aristotle of such credit with them but that when his Opinion was against theirs they could slight him Whatsoever he says is impossible in nature they can prove well enough to be possible from the Almighty Power of God who can make many Bodies to be in one and the self-same place and one Body to be in many places at the same time if the Doctrine of Transubstantiation require it though Aristotle deny it I like not the Design of drawing Religion into an Art whereas it ought to be a Law and though not the same in all Countries yet in every Country undisputable nor that they teach it not as Arts ought to be taught by shewing first the meaning of their Terms and then deriving from them the truth they would have us believe nor that their Terms are for the most part unintelligible though to make it seem rather want of Learning in the Reader than want of fair dealing in themselves They are for the most part Latin and Greek words wryed a little at the point towards the Native Language of the several Countries where they are used But that which is most intolerable is that all Clerks are forced to make as if they believed them if they mean to have any Church-preferment the Keys whereof are in the Pope's Hands and the Common People whatsoever they believe of those subtile Doctrines are never esteemed better Sons of the Church for their Learning There is but one way there to Salvation that is extraordinary Devotion and Liberality to the Church and readiness for the Churches sake if it be requir'd to fight against their Natural and Lawful Sovereigns B. I see what use they make of Aristotle's Logick Physicks and Metaphysicks but I see not yet how his Politicks can serve their turn A. Nor I. It has I think done them no good though it has done us here much hurt by accident for men grown weary at last of the Insolence of the Priests and examining the truth of these Doctrines that were put upon them began to search the sense of the Scriptures as they are in the learned Languages and consequently studying Greek and Latin became acquainted with the Democratical Principles of Aristotle and Cicero and from the love of their Eloquence fell in love with their Politicks and that more and more till it grew into the Rebellion we now talk of without any other advantage to the Roman Church but that it was a weakening to us whom since we broke out of their Net in the time of Henry the 8 th they have continually endeavoured to recover B. What have they gotten by the teaching of Aristotle's Ethicks A. It is some advantage to them that neither the Morals of Aristotle nor of any other have done them any harm nor us any good Their Doctrines have caused a great deal of dispute concerning Vertue and Vice
a little more slowly For you may have observed that when it snows in the South Parts the flakes of Snow are not so great as in the North which is a probable sign they fall in the South from a greater height and consequently disperse themselves more as water does that falls down from a high and steep Rock A. 'T is not improbable B. In natural causes all you are to expect is but probability which is better yet then making Gravity the cause when the cause of Gravity is that you desire to know and better then saying the Earth draws it when the Question is how it draws A. Why does the Earth cast off Air more easily than it does Water or any other heavy bodies B. It is indeed the Earth that casteth off that Air which is next unto it But it is that Air which casteth off the next Air and so continually Air moveth Air which it can more easily do then any other thing because like bodies are more susceptible of one anothers motions as you may see in two Lute-strings equally strained what motion one string being stricken communicates to the Air the same will the other receive from the Air but strained to a differing note will be less or not at all moved For there is no body but Air that hath not some internal though invisible motion of its parts And it is that internal motion which distinguisheth all natural bodies one from another A. What is the cause why certain Squibs though their substance be either Wood or other heavy matter made hollow and filled with Gunpowder which is also heavy do nevertheless when the Gunpowder is kindled fly upwards B. The same that keeps a man that swims from sinking though he be heavier then so much water He keeps himself up and goes forward by beating back the water with his Feet and so does a Squib by beating down the Air with the stream of the fired Gunpowder that proceeding from its Tail makes it recoil A. Why does any Brass or Iron Vessel if it be hollow flote upon the water being so very heavy B. Because the Vessel and the Air in it taken as one body is more easily cast off than a body of water equal to it A. How comes it to pass that a Fish especially such a broad Fish as a Turbut or a Plaice which are broad and thin in the bottom of the Sea perhaps a mile deep is not press'd to death with the weight of water that lies upon the back of it B. Because all heavy bodies descend towards one point which is the Center of the Earth and consequently the whole Sea descending at once does arch it self so as that the upper parts cannot press the parts next below them A. It is evident Nor can there be possibly any weight as some suppose there is of a Cylinder of Air or Water or of any other liquid thing while it remains in its own Element or is sustained and inclosed in a Vessel by which one part cannot press the other CHAP. II. Problems of Tides A. WHat makes the Flux and Reflux of the Sea twice in a natural day B. We must come again to our Basen of water wherein you have seen whilst it was moved how the water mounteth up by the sides and withal goes circling round about Now if you should fasten to the inside of the Basen some bar from the bottom to the top you would see the water instead of going on go back again from that bar ebbing and the water on the other side of the bar to do the same but in counter-time and consequently to be highest where the contrary streams meet together and then return again marking out four quarters of the Vessel two by their meeting which are the high waters and two by their retiring which are the low waters A. What bar is that you find in the Ocean that stops the current of the water like that you make in the Basen B. You know that the main Ocean lies East and West between India and the Coast of America and again on the other side between America and India If therefore the Earth have such a motion as I have supposed it must needs carry the current of the Sea East and West In which course the bar that stoppeth it is the South part of America which leaves no passage for the water but the narrow Streight of Magellan The Tide rises therefore upon the Coast of America And the rising of the same in this part of the world proceedeth from the swelling chiefly of the water there and partly also from the North Sea which lieth also East and West and has a passage out of the South Sea by the Streight of Anian between America and Asia A. Does not the Mediterranean Sea lie also East and West why are there not the like Tides there B. So there are proportionable to their lengths and quantity of water A. At Genoa at Ancona there are none at all or not sensible B. At Venice there are and in the bottom of the Streights and a current all along both the Mediterranean-Sea and the Gulf of Venice And it is the current that makes the Tides unsensible at the sides but the check makes them visible at the bottom A. How comes it about that the Moon hath such a stroke in the business as so sensibly to encrease the Tides at Full and Change B. The motion I have hitherto supposed but in the Earth I suppose also in the Moon and in all those great Bodies that hang in the Air constantly I mean the Stars both fixed and errant And for the Sun and Moon I suppose the Poles of their motion to be the Poles of the Aequinoctial which supposed it will follow because the Sun the Earth and the Moon at every Full and Change are almost in one streight line that this motion of the Earth will be made swifter than in the Quarters For this motion of the Sun and Moon being communicated to the Earth that hath already the like motion maketh the same greater and much greater when they are all three in one streight line which is only at the Full and Change whose Tides are therefore called Spring Tides A. But what then is the cause that the Spring-Tides themselves are twice a year namely when the Sun is in the Equinoctial greater than at any other times B. At other times of the year the Earth being out of the Aequinoctial the motion thereof by which the Tides are made will be less augmented by so much as a motion in the obliquity of 23 degrees or thereabout which is the distance between the Aequinoctial and Ecliptick Circles is weaker then the motion which is without obliquity A. All this is reasonable enough if it be possible that such motions as you suppose in these bodies be really there But that is a thing I have some reason to doubt of For the throwing off of Air consequent to these motions is the cause
strong drinks B. As for Oyl I never saw any inflamed by it self how much soever Heated therefore I do not think they are the parts of the Oyl but of the combustible body oyled that shine but the parts of Wine and strong Drinks have partly a strong Motion of themselves and may be made to shine but not with boiling but by adding to them as they rise the flame of some other body A. How can it be known that the particles of Wine have such a Motion as you suppose B. Have you ever been so much distempered with drinking Wine as to think the Windows and Table move A. I confess though you be not my Confessor I have but very seldom and I remember the window seemed to go and come in a kind of circling Motion such as you have described But what of that B. Nothing but that it was the Wine that caused it which having a good degree of that Motion before did when it was Heated in the Veins give that concussion which you thought was in the window to the Veins themselves and by the continuation of the parts of mans Body to the Brain and that was it which made the window seem to move A. What is Flame For I have often thought the Flame that comes out of a small heap of Straw to be more before it hath done Flaming then a hundred times the Straw it self B. It was but your Fancy If you take a stick in your hand by one end the other end burning and move it swiftly the burning end if the Motion be circular shall seem a circle if streight a streight line of Fire longer or shorter according to the swiftness of the Motion or to the space it moves in You know the cause of that A. I think it is because the impression of that visible Object which was made at the first instant of the Motion did last till it was ended For then it will follow that it must be visible all the way the impressions in all points of the time being equal B. The cause can be no other The smallest spark of Fire flying up seems a line drawn upward and again by that swift circular Motion which we have supposed for the cause of Light seems also broader then it is And consequently the Flame of every thing must needs seem much greater then it is A. What are those sparks that flie out of the Fire B. They are small pieces of the wood or Coals or other Fuel loosened and carried away with the Air that cometh up with them And being extiguished before their parts be quite dissipated into others are so much Soot and black and may be fired again A. A Spark of Fire may be stricken out of a cold stone It is not therefore Heat that makes this shining B. No 'T is the Motion that makes both the Heat and shining and the stroke makes the Motion For every of those Sparks is a little parcel of the stone which swiftly moved imprinteth the same Motion into the matter prepared or fit to receive it A. How comes the Light of the Sun to burn almost any combustible matter by rerefraction through a convex glass and by reflection from a concave B. The Air moved by the Sun presseth the convex glass in such manner as the action continued through it proceedeth not in the same streight line by which it proceeded from the Sun but tendeth more toward the center of the body it enters Also when the action is continued through the convex body it bendeth again the same way By which means the whole action of the Sun-beams are enclosed within a very small compass in which place therefore there must be a very vehement Motion and consequently if there be in that place combustible matter such as is not very hard kindle the parts of it will be dissipated and receive that Motion which worketh on the Eye as other Fire does The same reason is to be given for burning by Reflection For there also the Beams are collected into almost a point A. Why may not the Sun-beams be such a Body as we call Fire and pass through the pores of the glass so disposed as to cary them to a point or very near B. Can there be a glass that is all pores If there cannot then cannot this effect be produced by the passing of Fire through the pores You have seen men llght their Tobacco at the Sun with a burning glass or with a ball of Cristal held which way they will indifferently Which must be impossible unless the ball were all pores Again neither you nor I can conceive any other Fire then we have seen nor then such as water will put out But not only a solid Globe of Glass or Cristal will serve for a burning Glass but also a hollow one filled with water How then does the Fire from the Sun pass through the glass of water without being put out before it come to the matter they would have it burn A. I know not There comes nothing from the Sun If there did there is come so much from it already that at this day we had had no Sun CHAP. V. Problems of Hard and Soft A. WHat call you Hard and what Soft B. That body whereof no one part is easily put out of its place without removing the whole is that which I and all men call Hard and the contrary Soft So that they are but degrees one of another A. What is the cause that makes one body Harder then another or seeing you say they are but degrees of one another what makes one body Softer then another and the same body sometimes Harder sometimes Softer B. The same Motion which we have supposed from the beginning for the cause of so many other effects Which Motion not being upon the center of the part moved but the part it self going in another circle to and again it is not necessary that the Motion be perfectly circular For it is not circulation but the reciprocation I mean the to and again that does cast off and lacerrate the Air and consequently produce the fore-mentioned effects For the cause therefore of Hardness I suppose the reciprocation of Motion in those things which are Hard to be very swift and in very small circles A. This is somewhat hard to believe I would you could supply it with some visible experience B. When you see for example a Cross-bow bent do you think the parts of it stir A. No. I am sure they do not B. How are you sure You have no argument for it but that you do not see the Motion When I see you sitting still must I believe there is no Motion in your parts within when there are so many arguments to convince me there is A. What argument have you to convince me that there is Motion in a Cross-bow when it stands bent B. If you cut the string or any way set the Bow at liberty it will have then a very visible Motion What
in pieces A. 'T is like enough to be so And if nature have betrayed her self in any thing I think it is in this and in that other experience of the Cross-bow which strongly and evidently demonstrates the internal reciprocation of the Motion which you suppose to be in the internal parts of every Hard body And I have observed somewhat in Looking-glasses which much confirms that there is some such Motion in the internal parts of Glass as you have supposed for the cause of Hardness For let the Glass be AB and let the Object at C be a Candle and the Eye at D. Now by divers Reflections and Refractions in the two superficies of the Glass if the Lines of Vision be very oblique you shall see many images of the Candle as E F G in such order and position as is here described But if you remove your Eye to C and the Candle to D they will appear in a situation manifestly different from this Which you will yet more plainly perceive if the Looking-Glass be coloured as I have observed in Red and Blew Glasses and could never conceive any probable cause of it till now you tell me of this secret Motion of the parts across the grain of the Glass acquired by cooling it this or that way B. There be very many kinds of Hard bodies Metals Stones and other kinds in the bowels of the Earth that have been there ever sence the beginning of the World and I believe also many different sorts of Juices that may be made Hard But for one general cause of Hardness it can be no other then such an internal Motion of parts as I have already described whatsoever may be the cause of the several concomitant qualities of their Hardness in particular A. We see water Hardened every Frosty day It 's likely therefore you may give a pribable cause of Ice What is the cause of Freezing of the Ocean towards the Poles of the Earth B. You know the Sun being always between the Tropicks and as we have supposed always casting off the Air and the Earth likewise casting it off from it's self there must needs on both sides be a great Stream of Air towards the Poles shaving the superficies of the Earth and Sea in the Northern and Southern Climates This shaving of the Earth and Sea by the Stream of Air must needs contract and make to shrink those little Circles of the internal parts of Earth and Water and consequently Harden them first at the superficies into a thin skin which is the first Ice and afterwards the same Motion continuing and the first Ice co-operating the Ice becomes thicker And this I conceive to be the cause of the Freezing of the Ocean A. If that be the cause I need not ask how a Bottle of water is made to Freeze in warm weather with Snow or Ice mingled with Salt For when the Bottle is in the midst of it the Wind that goeth out both of the Salt and of the Ice as they dissolve must needs shave the superficies of the Bottle and the Bottle work accordingly on the water without it and so give it first a thin skin and at last thicken it into a solid piece of Ice But how comes it to pass that water does not use to Freeze in a deep Pit B. A deep Pit is a very thick Bottle and such as the Air cannot come at but only at the top or where the Earth is very loose and spungy A. Why will not Wine Freeze as well as Water B. So it will when the Frost is great enough But the internal Motion of the parts of Wine and other Heating Liquors is in greater Circles and stronger then the Motion of the parts of water and therefore less easily to be Frozen especally quite through because those parts that have the strongest Motion retire to the center of the Vessel CHAP. VI. Problems of Rain Wind and other WEATHER A. WHat is the original cause of Rain and how is it generated B. The motion of the Air such as I have described to you already tending to the dis-union of the parts of the Air must needs cause a continual endeavour there being no possibility of Vacuum of whatsoever fluid parts there are upon the face of the Earth and Sea to supply the place which would else be empty This makes the water and also very small and loose parts of the Earth and Sea to rise and mingle themselves with the Air and to become mist and Clouds Of which the greatest quantity arise there where there is most water namely from the large parts of the Ocean which are the South Sea the Indian Sea and the Sea that divideth Europe and Africa from America over which the Sun for the greatest part of the year is perpendicular and consequently raiseth a greater quantity of water Which afterwards gathered into Clouds falls down in Rain A. If the Sun can thus draw up the water though but in small drops why can it not as easily hold it up B. It is likely it would also hold them up if they did not grow greater by meeting together nor were carried away by the Air towards the Poles A. What makes them gather together B. It is not improbable that they are carried against Hills and there stopt till more overtake them And when they are carried towards the North or South where the force of the Sun is more oblique and thereby weaker they descend gently by their own weight And because they tend all to the center of the Earth they must needs be united in their way for want of room and so grow bigger And then it Rains A. What is the reason it Rains so seldom but Snows so often upon very high Mountains B. Because perhaps when the water is drawn up higher then the highest Mountains where the course of the Air between the Aequator and the Poles is free from stopping the Stream of the Air Freezeth it into Snow And 't is in those places only where the Hills shelter it from that Stream that it falls in Rain A. Why is there so little Rain in Egypt and yet so much in other parts nearer the Aequinoctial as to make the Nile overflow the Countrey B. The cause of the falling of Rain I told you was the the stopping and consequently the collection of Clouds about great Mountains especially when the Sun is near the Aequinoctial and thereby draws up the water more potently and from greater Seas If you consider therefore that the Mountains in which are the springs of Nile lye near the Aequinoctial and are exceeding great and near the Indian Sea you will not think it strange there should be great store of Snow This as it melts makes the Rain of Nile to rise which in April and May going on toward Egypt arrived there about the time of the Solstice and overflow the Countrey A. Why should not the Nile then overflow that Countrey twice a year For it comes twice
pass through a Body of less into a Body of greater resistance and to the Point of the Superficies it falleth on you draw a Line Perpendicular to the same superficies the Action will proceed not in the same Line by which it fell on but in another Line bending toward that Perpendiculare A. What is the reason of that B. I told you before that the falling on worketh only in the Perpendicular But as soon as the Action proceedeth further inward then a meer touch it worketh partly in the Perpendicular and partly forward and would proceed in the same line in which it fell on but for for the greater resistance which now weakneth the Motion forward and makes it to incline towards the Perpendicular A. In transparent Bodies it may be so but there be Bodies through which the Light cannot pass at all B. But the Action by which Light is made passeth through all Bodies For this Action is Pression and whatsoever is prest presseth that which is next behind and so continually But the cause why there is no Light seen through it is the uneveness of the parts within whereby the Action is by an infinite number of Reflections so diverted and weakned that before it hath proceeded through it hath not strength left to work upon the Eye strongly enough to produce sight A. If the Body being transparent the Action proceed quite through into a Body again of less resistance as out of Glass into the Air which way shall it then proceed in the Air B. From the Point where it goeth forth draw a Perpendicular to the superficies of the Glass the Action now freed from the resistance it suffered will go from that Perpendicular as much as it did before come towards it A. When a Bullet from out of the Air entreth into a Wall of Earth will that also be Refracted towards the Perpendicular B. If the Earth be all of one kind it will For the parallel Motion will there also at the first entrance be resisted which it was not before it entred A. How then comes a Bullet when shot very Obliquely into any broad Water and having entred yet to rise again into the Air B. When a Bullet is shot very Obliquely though the Motion be never so swift yet approach downwards to the Water is very slow and when it cometh to it it casteth up much Water before it which with its weight presseth downwards again and maketh the Water to rise under the Bullet with force enough to master the weak Motion of the Bullet downwards and to make it rise in such manner as Bodies use to rise by Reflection A. By what Motion seeing you ascribe all Effects to Motion can a Load-stone draw Iron to it B. By the same Motion hitherto supposed But though all the smallest parts of the Earth have this Motion yet it is not supposed that their Motions are in equal Circles nor that they keep just time with one another nor that they have all the same Poles If they had all Bodies would draw one another alike For such an agreement of Motion of Way of Swiftness of Poles cannot be maintained without the conjunction of the Bodies themselves in the Center of their common Motion but by violence If therefore the Iron have but so much of the Nature of the Load-stone as redily to receive from it the like Motion as one String of a Lute doth from another String strained to the same Note as it is like enough it hath the Load-stone being but one kind of Iron Ore it must needs after that Motion received from it unless the greatness of the weight hinder come nearer to it because at distance their Motions will differ in time and oppose each other whereby they will be forced to a common Center If the Iron be lifted up from the Earth the Motion of the Load-stone must be stronger or the Body of it nearer to overcome the Weight and then the Iron will leap up to the Load-stone as as Swiftly as from the same distance it would fall down to the Earth but if both the Stone and the Iron be set floating upon the Water the attraction will begin to be manifest at a greater distance because the hindrance of the weight is in part removed A. But why does the Load-stone if it float on a Calm Water never fail to place it self at last in the Meridian just North and South B. Not so just in the Meridian but almost in all places with some variations But the cause I think is that the Axis of this Magnetical Motion is parallel to the Axis of the Ecliptique which is the Axis of the like Motion in the Earth and consequently that it cannot freely exercise its Natural Motion in any other Scituation A. Whence may this consent of Motion in the Load-stone and the Earth proceed Do you think as some have written that the Earth is a great Load-stone B. Dr. Gilbert that was the first that wrote any thing of this Subject rationally inclines to that opinion Decartes thought the Earth excepting this upper crust of a few Miles depth to be of the same Nature with all other Stars and bright For my part I am content to be ignorant but I believe the Load-stone hath given its virtue by a long habitude in the Mine the Vein of it lying in the plain of some of the Meridians or rather of some of the great Circles that pass through the Poles of the Ecliptique which are the same with the Poles of the like Motion supposed in the Earth A. If that be true I need not ask why the filings of Iron laid on a Load-stone equally distant from its Poles will lie parallel to the Axis but one each side incline to the Pole that is next it Nor why by drawing a Load-stone all a long a Needle of Iron the Needle will receive the same Poles Nor why when the Load-stone and Iron or two Load-stones are put together floating upon Water will fall one of them a Stern of the other that their like parts may look the same way and their unlike touch in which Action they are commonly said to Repel one another For all this may be deriv'd from the union of their Motions One thing more I desire to know and that is What are those things they call Spirits I mean Ghosts Fairies Hobgoblins and the like Apparitions B. They are no part of the Subject of Natural Philosophy A. That which in all Ages and all places is commonly seen as those have been unless a great part of Mankind by Lyers cannot I think be supernatural B. All this that I have hitherto said though upon better ground than can be had for a discourse of Ghosts you ought to take but for a Dream A. I do so But there be some Dreams more like sense then others And that which is like sense pleases me as well in natural Philosophy as if it were the very truth B. I was Dreaming also once of these
Act of Parliament for the abolishing the High Commission But though the High Commission were taken away yet the Parliament having other ends besides the setting up of the Presbyterate pursued the Rebellion and put down both Episcopacy and Monarchy erecting a power by them called The Common-wealth by others the Rump which men obeyed not out of Duty but for fear nor was there any humane Laws left in force to restrain any man from Preaching or Writing any Doctrine concerning Religion that he pleased and in this heat of the War it was impossible to disturb the Peace of the State which then was none And in this time it was that a Book called Leviathan was written in defence of the King's Power Temporal and Spiritual without any word against Episcopacy or against any Bishop or against the publick Doctrine of the Church It pleas'd God about Twelve years after the Usurpation of this Rump to restore His most Gracious Majesty that now is to his Fathers Throne and presently His Majesty restored the Bishops and pardoned the Presbyterians but then both the one and the other accused in Parliament this Book of Heresie when neither the Bishops before the War had declared what was Heresie when if they had it had been made void by the putting down of the High Commission at the importunity of the Presbyterians So fierce are men for the most part in dispute where either their Learning or Power is debated that they never think of the Laws but as soon as they are offended they cry out Crucifige forgetting what St. Paul saith even in case of obstinate holding of an Error 2 Tim. 2.24 25. The Servant of the Lord must not strive but be gentle unto all men apt to teach patient in meekness instructing those that oppose if God peradventure may give them repentance to the acknowledging of the truth Of which counsel such fierceness as hath appeared in the Disputation of Divines down from before the Council of Nice to this present time is a Violation FINIS SEVEN Philosophical Problems AND TWO PROPOSITIONS OF GEOMETRY By Thomas Hobbes of Malmesbury With an Apology for Himself and his WRITINGS Dedicated to the KING in the year 1662. LONDON Printed for William Crook at the Green-Dragon without Temple-Bar 1682. TO THE KING THat which I do here most humbly present to Your Sacred Majesty is the best Part of my Meditations upon the Natural Causes of Events both of such as are commonly known and of such as have been of late artificially exhibited by the Curious They are ranged under seven Heads 1. Problems of Gravity 2. Problems of Tides 3. Problems of Vacuum 4. Problems of Heat 5. Problems of Hard and Soft 6. Problems of Wind and Weather 7. Problems of Motion Perpendicular and Oblique c. To which I have added Two Propositions of Geometry One is The Duplication of the Cube hitherto sought in vain The other A Detection of the absurd Use of Arithmetick as it is now applied to Geometry The Doctrine of Natural Causes hath not infallible and evident Principles For there is no Effect which the Power of God cannot produce by many several ways But seeing all Effects are produced by Motion he that supposing some one or more Motions can derive from them the necessity of that Effect whose Cause is required has done all that is to be expected from Natural Reason And though he prove not that the thing was thus produced yet he proves that thus it may be produced when the Materials and the power of Moving is in our hands which is as useful as if the Causes themselves were known And notwithstanding the absence of rigorous Demonstration this Contemplation of Nature if not rendred obscure by empty terms is the most Noble Imployment of the Mind that can be to such as are at leisure from their necessary Business This that I have done I know is an unworthy Present to be offered to a KING though considered as God considers Offerings together with the Mind and Fortune of the Offerer I hope will not be to Your Majesty unacceptable But that which I chiefly consider in it is that my Writing should be tryed by Your Majesties Excellent Reason untainted with the Language that has been invented or made use of by Men when they were puzzled and who is acquainted with all the Experiments of the time and whose approbation if I have the good Fortune to obtain it will protect my reasoning from the Contempt of my Adversaries I will not break the custom of joyning to my Offering a Prayer And it is That Your Majesty will be pleased to pardon this following short Apology for my Leviathan Not that I rely upon Apologies but upon Your Majesties most Gracious General Pardon That which is in it of Theology contrary to the general Current of Divines is not put there as my Opinion but propounded with submission to those that have the Power Ecclesiastical I did never after either in Writing or Discourse maintain it There is nothing in it against Episcopacy I cannot therefore imagine what reason any Episcopal-man can have to speak of me as I hear some of them do as of an Atheist or man of no Religion unless it be for making the Authority of the Church wholly upon the Regal Power which I hope Your Majesty will think is neither Atheism nor Heresie But what had I to do to meddle with matters of that nature seeing Religion is not Philosophy but Law It was written in a time when the pretence of Christ's Kingdom was made use of for the most horrid Actions that can be imagined And it was in just Indignation of that that I desired to see the bottom of that Doctrine of the Kingdom of Christ which divers Ministers then Preached for a Pretence to their Rebellion which may reasonably extenuate though not excuse the writing of it There is therefore no ground for so great a Calamny in my writing There is no sign of it in my Life and for my Religion when I was at the point of Death at St. Germains the Bishop of Durham can bear witness of it if he be asked Therefore I most humbly beseech Your Sacred Majesty not to believe so ill of me upon reports that proceed often and may do so now from the displeasure which commonly ariseth from difference in Opinion nor to think the worse of me if snatching up all the Weapons to fight against Your Enemies I lighted upon one that had a double edge Your Majesties Poor and most Loyal Subject THOMAS HOBBES PHILOSOPHICAL PROBLEMS· CHAP. I. Problems of Gravity A. WHat may be the cause think you that stones and other bodies thrown upward or carried up and left to their liberty fall down again for ought a man can see of their own accord I do not think with the old Philosophers that they have any love to the Earth or are sullen that they will neither go nor stay And yet I cannot imagine what body there is above
that should drive them back B. For my part I believe the cause of their descending is not in any natural appetite of the bodies that descend but rather that the Globe of the Earth hath some special motion by the which it more easily casteth off the Air than it doth other bodies And then this descent of those we call heavy bodies must of necessity follow unless there be some empty spaces in the world to receive them For when the Air is thrown off from the Earth somewhat must come into the place of it in case the world be full and it must be those things which are hardliest cast off that is those things which we say are heavy A. But suppose there be no place empty for I will defer the Question till anon how can the Earth cast off either the Air or any thing else B. I shall shew you how and that by a familiar Example If you lay both your hands upon a Basen with water in it how little soever and move it circularly and continue that motion for a while and you shall see the water rise upon the sides and fly over by which you may be assured that there is a kind of circulating motion which would cast off such bodies as are contiguous to the body so moved A. I know very well there is and it is the same motion which Country people use to purge their Corn For the Chaff and Straws by casting the Grain to the side of the Seive will come towards the middle But I would see the Figure B. Here it is There is a Circle pricked out whose Center is A and three less Circles whose Centers are B C D let every one of them represent the Earth as it goeth from B to C and from C to D always touching the uttermost Circle and throwing off the Air as is marked at E and F. And if the world were not full there would follow by this scattering of the Air a great deal of space left empty But supposing the world full there must be a perpetual shifting of the Air one part into the place of another A. But what makes a stone come down suppose from G B. If the Air be thrown up beyond G it will follow that at the last if the motion be continued all the Air will be above G that is above the stone which cannot be till the stone be at the Earth A. But why comes it down still with encreasing swiftness B. Because as it descends and is already in motion it receiveth a new impression from the same cause which is the Air whereof as part mounteth part also must descend supposing as we have done the plenitude of the world For as you may observe by the Figure the motion of the Earth according to the Diameter of the uttermost Circle is progressive and so the whole motion is compounded of two motions one circular and the other progressive and consequently the Air ascends and circulates at once And because the stone descending receiveth a new pressure in every point of its way the motion thereof must needs be accelerated A. 'T is true For it will be accelerated equally in equal times and the way it makes will encrease in a double proportion to the times as hath heretofore been demonstrated by Galileo I see the solution now of an Experiment which before did not a little puzzle me You know that if two plummets hang by two strings of equal length and you remove them from the perpendicular equally I mean in equal angles and then let them go they will make their turns and returns together and in equal times And though the arches they describe grow continually less and less yet the times they spend in the greater arches will still be equal to the time they spend in the lesser B. 'T is true Do you find any Experiment to the contrary A. Yes For if you remove one of the plummets from the perpendicular so as for example to make an angle with the perpendicular of 80 degrees and the other so as to make an angle of 60 degrees they will not make their turns and returns in equal times B. And what say you is the cause of this A. Because the arches are the spaces which these two motions describe they must be in double proportion to their own times which cannot be unless they be let go from equal altitudes that is from equal angles B. 'T is right and the Experiment does not cross but confirm the equality of the times in all the arches they describe even from 90 degrees to the least part of one degree A. But is it not too bold if not extravagant an assertion to say the Earth is moved as a man shakes a Basen or a Seive Does not the Earth move from West to East every day once upon his own Center and in the Ecliptick Circle once a year And now you give it another odd motion How can all these consist in one and the same body B. Well enough If you be a Shipboard under sail do not you go with the Ship Cannot you also walk upon the Deck Cannot every drop of bloud move at the same time in your veins How many motions now do you assign to one and the same drop of bloud Nor is it so extravagant a thing to attribute to the Earth this kind of motion but that I believe if we certainly knew what motion it is that causeth the descent of bodies we should find it either the same or more extravagant But seeing it can be nothing above that worketh this effect it must be the Earth it self that does it and if the Earth then you can imagine no other motion to do it withal but this And you will wonder more when by the same motion I shall give you a probable account of the causes of very many other works of Nature A. But what part of the Heaven do you suppose the Poles of your pricked Circle point to B. I suppose them to be the same with the Poles of the Ecliptick For seeing the Axis of the Earth in this Nation and in the annual motion keeps parallel to it self the Axis must in both motions be parallel as to sense For the Circle which the Earth describes is not of visible magnitude at the distance it is from the Sun A. Though I understand well enough how the Earth may make a stone descend very swiftly under the Ecliptick or not far from it where it throws off the Air perpendicularly yet about the Poles of the Circle methinks it should cast off the Air very weakly I hope you will not say that bodies descend faster in places remote from the Poles than nearer to them B. No but I ascribe it to the like motion in the Sun and Moon For such motions meeting must needs cast the stream of the Air towards the Poles And then there will be the same necessity for the descent there that there is in other places though perhaps
