are likewise streightned by constriction of the same nerves Whether this ingenious conjecture be true or not certain it is that the Matter of Tears is the same with the liquor of the Lymphae-ducts and that they flow from the aforesaid Glandules which are therefore named Lacrymales And as for the manner of their Expression from thence in some passions of the Mind the most rational account I have hitherto met with concerning it is this When any occasion of weeping occurrs and affects the Sensitive Soul instantly the Ventricles of the heart with all the Praecordia are by the blood in abundance brought into them more than usualy crowded and distended and the Lungs also stuffed and inflated so that they cannot perform the action of respiration but by sobbs intermixed and the Midriff to give room to such distension of the heart and Lungs is pressed downward with a more intense contraction alternately succeeding which great depression and brisk contraction being repeted is the efficient cause of Sobbing and at the same time the air being with difficulty admitted into the lungs by reason they and the Midriff are so exceedingly distended and with no less difficulty exploded again by the windpipe thence comes that whining sound of crying and howling To this affection of the vitals the parts of the face also being distorted into a sad and mournfull aspect exactly correspond because the nerves which contract the Praecordia have a communion of continuity and cooperate with those which are inserted into the muscles of the face and which compose it into the postures of weeping and laughter in passion Nor doth the disorder cease here but extend itself to the upper region also to the brain where the Spirits being put into confusion and the arteries surcharged with too great an afflux of blood from the oppressed heart the palace of the Soul itself is brought into danger of a purple deluge For prevention whereof the nerves incircling and binding the trunks of the arteries in many places strongly constringe them so that the commotion of the blood is much repressed the liquor thereof in the beginning of the passion highly rarefied suddainly condensed and the serous part of it being put into a flux is transmitted into the above mentioned Glandules of the Eyes there placed and destined by nature to receive it And then because these Glandules are in like manner constringed and as it were squeez'd by certain nerves that are of the same original and community with the Pathetic nerves of the face and heart the serous liquor is expressed out of them through their excretory channels leading to the corners of the Eyes most accurrately described with their uses by that diligent Anatomist Nichol. Steno in a singular treatise and forced to distill in a shower of tears the strong Contraction of the membranes investing the whole brain concurring to that expression The same may be said likewise of the shedding tears for Ioy. For in suddain and great Ioy conjoyned with Admiration the Sensitive Soul very much expanding herself and diffusing the Animal Spirits the blood is sent from the heart in great abundance to the brain so as to distend the vessels that contain it which being soon after strongly contracted again by the same Soul withdrawing herself inward as if she feared a dissolution by so ample an Effusion the blood is in a sort put into a flux or melted and the serous part of it separated in the Glandules of the Eyes and thence by constriction of the nerves squeezed forth in tears This being supposed it will not be difficult for us thence to infer that Infants and Old Men are indeed more prone to weep than those of middle age but for divers reasons Old Men for the most part weep out of Love and Ioy together because both these affections causing a great Effusion of the Sensitive Soul and consequently a large apertion of the orifices or sluices of the heart must therefore especialy where they are conjoyned cause also a transmission of the blood from thence to the brain in great abundance and the blood being generaly more thin and diluted with serum in old men must yield more matter for their tears But Infants commonly weep out of mere Sorrow and vexation such as is not accompanied with the least of Love because the contraction of the Soul and nerves caused by sorrow expresseth out of the blood which is alwaies abundant in children brought by the arteries to the brain a sufficient quantity of serum to replenish the Glandulae Lachrymales and supply the sourse of their tears There remains yet that other Sign of Sorrow which doth usually accompany it when it is profound and extreme and that is Sighing the cause whereof is very much different from that of weeping though both proceed from Grief For the same occasion that moves us to shed tears when our Lungs are stuffed and distended with blood provokes us also to fetch deep sighs when they are almost empty and when some sudden imagination of Hope or comfort opens the sluice of the Arteria Venosa in the lungs which sorrow had lately contracted For then that little blood that remained in the lungs in a moment passing down through that pipe into the left ventricle of the heart the ambient aire instantly rusheth by the mouth into the lungs to replenish that place the blood had left free and this great and quick repletion of the lungs with aire is what we call Sighing You have now heard what Conjectures seem to me most consentaneous to reason and Anatomical observations concerning the Corporeal Motions excited in those two eminent passions Joy and Sorrow with their usual Adjuncts Laughter and weeping be pleas'd to hear also a few words touching the more violent motions proper to Anger which I have promised next to consider That the Effects of this most vehement Commotion of the Sensitive Soul are various not only as the occasion or injury is conceived to be greater or less but also according to the various temperaments of persons and to the diversity of other Passions conjoyned therewith is obvious to common observation and we have already hinted And from this variety it is that men have distinguished Anger into Harmless and Dangerous or simple heat of blood and thirst after Revenge assigning moreover to each sort its proper Signs or Characters observable in the outward parts of the body and especially in the face For some when they are angry look pale or tremble others grow red or weep and the vulgar judgeth the passion of the first sort to be much more dangerous than that of the other Whereof the reason may be this that when we either will not or cannot shew our resentments and revenge otherwise than by our change of countenance and by words we then put forth all our heat and exert all our force at the very beginning of the commotion so that the blood being in this sudden effort copiously effused
Coextense to the whole Body of a Substance either Fiery or meerly resembling Fire of a consistence most thin and subtile not much unlike the flame of of pure spirit of Wine burning in a paper Lantern or other the like close place First I think it to be Corporeal Divisible and Coextense to the whole Body and that for two reasons among many others not the least considerable One is this that many and divers Animal actions are daily observed to be at one and the same time performed by divers Parts and Members of the Body for instance the Eye sees the Ear hears the Nostrils smell the Tongue tasteth and all exteriour Members exercise their Sense and Motion all at once For as much then as betwixt the Body and Soul of a Brute there is no Medium both being intimately connexed but the Members and Parts of the Body are Instruments fram'd for the use of the Soul what else can be imagined but that many and distinct portions of the Soul so extended do inform and actuate the distinct Organs and Members of the Body each in a peculiar manner respective to the peculiar Constitution Fabrique and Office thereof The Other this it is observed also that Vipers Eels Earthworms and most other Reptils being cut into many pieces all pieces for a good while after retain a manifest Motion and no obscure sense for being prick'd they contract and shrink up themselves as sensible of the Hurt and striving to avoid it And this probably from hence that these less perfect Animals having their liquors both Vital and Animal of a consistence viscous and not easily dissoluble or dissipable and having their Soul if not equally yet universally diffused and all its parts subsisting immediately in those liquors cannot suffer a division of their Body without division of their Soul also the parts whereof residing for some time after in the segments of the Body may perhaps for that time continue to actuate them to Motion and Sense It hath been more then once unhappily Experimented that the Head of a Viper hath bitten a Mans Finger and Poysoned him too above an hour after it had been cut off Not by involuntary convulsion of the Nerves and Muscles of the Vipers Jaws such as not rarely happen to Animals in the torments of Death for those probably could neither last so long nor so regularly open and shut the mouth and extend the two fang teeth by contraction of their erecting Muscles but certainly by an action voluntary regular and suggested by sense and perhaps revenge too Whence I am apt to suspect that not only part of the Vipers Soul but Anger and Revenge also survived in the divided head For it is well known the bite of a Viper is never Venomous but when he is enraged the Chrystalline liquor contained in the two little Glandules at the roots of his fang teeth being then by a copious afflux of Spirits from the Brain and other brisk motions thereupon impress'd in anger of all passions the most violent and impetuous so altered and exalted as to become highly active and venenate whereas at other times when a Viper is not offended and provok'd the same Liquor is found to be as harmless as the spittle of a Man in perfect health But whether from the dangerous effects of this biting the dire Symptoms that thereupon ensued it be inferrible or not that in the abscinded head of the beast there remained anything of Anger and Revenge in my poor judgment 't is very evident from the very act of biting there still remained somwhat of life sense and voluntary motion Which is sufficient to verify my present supposition that a Sensitive Soul is divisible and coextense to the whole body it animates Secondly I think the same Sensitive Soul to consist of Fire or some matter analogous to Fire and the Reasons inducing me to be of this opinion are many Some I have formerly alleadged where I discourse of the Flame of life perpetually arising from accension of the Sulphureous and inflammable parts of the blood while circulated through the heart and lungs which therefore I abstain from reciting in this place Others that have since occurr'd to my consideration I am obliged here to expose to yours That the Life or Soul of Brute Animals is seated principally in their Blood we are plainly taught even by the Oracle of truth itself the dictates of the Divine Wisdom that created them and that Blood and Fire subsist by the same principles viz. Aliment and Ventilation is evident from hence that a defect of either of these doth equally destroy both the one and the other Should you here exact from me some description of the Essence of Fire I should adventure to tell you that it seems to be only a multitude of most minute and subtile particles mutually touching each other put into a most rapid motion and by continual succession of some parts and decession of others renewed which conserves its motion and subsistence by preying upon and consuming the Sulphureous parts of its subject matter or fewel and the Nitrous parts of the ambient aer For even our sense bears witness that from the particles of this twofold aliment Sulphureous and Nitrous resolved to the last degree of smalness and by a most violent and rapid motion agitated the forms of Fire and Flame which differ only in degrees of density and velocity of motion do wholy result Nor doth the image I find drawn in my brain of the Soul of a Brute much differ from this description of the nature of Fire I conceive it to be no other than a certain congregation of most minute subtil and agile particles corpuscles or atoms call them what you please crowded together which being in the very first moment of life put into brisk and most rapid motion like that of the particles of Fire when first kindled do so long conserve that motion and their own subsistence as they have a continued supply of convenient nutriment sulphureous from the blood within Nitrous from the aer without and no longer For we cannot but observe that the Souls of all Brute Animals of what kind soever stand perpetually in need of a fresh supply of those two sorts of aliment insomuch that so soon as the recruit fails they languish and dye no otherwise than the flame of a lamp grows weak and dim and is extinguished for want of oyl or air But what is very remarkable besides fire and life there is not to be found in all nature any other thing whatsoever to whose act and subsistence such a supply of Sulphureous and Nitrous matter is necessary Nor is any other motion in the World whether it be of fermentation ebullition vegetation or other whatever besides that of Fire and Life subject to be arrested and suppressed immediately from defect of aer It was not then without very great reason that our Master Hippocrates affirmed 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 that the Soul is
being interrupted is forced to undergo irregular floods and ebbs and other violent fluctuations but the Animal spirits also impelled to and fro in a tumultuous manner cause great disorders in the functions of sense and motion yea more by their exorbitant manner of influx into the nerves of the Heart and Lungs they move them irregularly and so contribute to render the course of the blood yet more unequal Nor doth the tempest stop here it extends sometimes also to other Humors of the body to the solid parts and members of it and even to the discomposure of the Reasonable Soul her self The Tranquillity of the Sensitive Soul is easily observable in sleep when the spirits are bound up or at least at rest and very often also when we are awake namely whensoever the objects affecting the sense or created in the imagination appear to import neither good nor evil to us and we are no further concerned than barely to apprehend and know them For then they smoothly and calmly slide into the common sensory and imagination and soon pass away without any the least disquiet or commotion of the appetite The Perturbation of it is as easily manifest in all the passions which are the consequents of desire or of aversation For when any object is represented under the apparence of good or evil to us in particular instantly the Sensitive Soul is moved to imbrace or avoid it and imployes not only the Animal Spirits her Emissaries but the blood also and other humors universally diffused through the body and even the solid parts too as instruments to effect her design More plainly when the Imagination conceives any thing to be embraced as good or avoided as evil presently by the spirits residing in the brain and ranged as it were into order the Appetite is formed and then the impression being transmitted to the Heart according as that is contracted or dilated the blood is impelled and forced to various fluctuations and irregular motions and thence the Appetite being by instinct transmitted to the nerves ordained for that use they cause motions of the solid parts respective thereunto And this we may conjecture to be the order of motions excited successively in the phantasy spirits blood and solid parts in every Passion of the mind of what sort soever Nor can it indeed sink into my dull head by what other means of mutual intercourse besides such a quick transmission of spirits first from the brain into the Praecordia and thence back again to the brain by nerves to that end extended betwixt those sources of life and sense the great and speedy commerce in all passions observed to be maintained between them can be effected But however this admirable Commerce may be otherwise explained it is lawful for us us to conceive that the Sensitive Soul when put into this state of perturbation doth strangely vary her Postures according to the diversity of motions caused in her and though that diversity be very great yet that in all perturbations whatever she is more or less amplified so as to swell beyond her ordinary bounds or more or less contracted within her self so as to be less extense or diffused than usually she is at other times in her state of tranquillity as will be exemplified in all the passions we design particularly to describe Mean while it is observable that sometimes she being affected with joy or pride and as it were exulting above measure doth advance and expand her self as if she strove to be greater and to stretch her grandure beyond the narrow limits of the body Whereupon the Animal Spirits being respectively commoved in the brain enlarge the sphere of their irradiation and by a more abundant influx vigorously agitate the Praecordia or vital parts so forcing the blood to flow more copiously into all parts and to diffuse it self more freely and speedily through the whole body On the contrary sometimes being surprised with grief or fear she contracts her self into a narrower compass so that shrunk up to a scantling less than her usual circuit of emanation she becomes of too small a size vigorously to actuate the body as she ought Whence the Animal faculties drooping as it were perform their actions either slowly and weakly or perversly and the Praecordia wanting their due influx of spirits almost flagg suffering the blood to remain in their conduits longer than it ought even to danger of stagnation and consequently of sudden death These two contrary Motions therefore of Contraction and Expansion I suppose to be the two General ones to which all the various Postures of the Sensitive Soul when she is perturbed may be commodiously referr'd it seeming to me considering her to be exactly like a Flame and obnoxious to the like accidental mutations that she is not naturally capable of other besides these and that how great soever the variety of such her Mutations may be in the vast diversity of Passions yet they are all but several degrees and divers modes of either her Extension or Contraction This being then supposed I proceed to the first and General Causes of all Passions Where I observe first what was only hinted a little afore that it is not the simple representation of good or evil in any object how great soever it be that is sufficient to raise Commotion in the sensitive Soul for we usualy without perturbation behold the prosperous or adverse events befalling other Men no waies related to us and therefore it is further required to the moving our affections that the good or evil apprehended be by us conceived to concern ourselves in particular or our Friends at least and near relations who in this case are part of our selves Secondly that even that good or evil wherein a Man conceives himself to be concern'd is not always apprehended by him under one and the same ration or aspect but variously aswell in respect of the object itself as of the Subject to which it doth more peculiarly and immediately appertain Of the divers rations under which one and the same object good or evil may be apprehended by one and the same Man respectively to the various circumstances thereof we shall more opportunely speak anon And as for those that respect the Subject or Man apprehending it is worthy our serious remark That all Good or Evil represented to Man doth concern the Sensitive Soul either as she is distinct from the body and abstract from all relation or as she is intimately conjoyn'd to the body and interressed therein or finally as she is subordinate to the Rational Soul For though every Affect or Passion be founded in the Corporeal Soul yet it always respects the good or evil of one or other of these three subjects and is first raised on the behalf of this that or the other Wherefore according to this triple relation of the Sensitive Soul all Passions incident thereto may be said to be either Physical or Metaphysical or
Moral of which in their order 1. Passions meerly Physical or which properly belong to the Sensitive Soul alone are those natural and occult inclinations and aversations commonly call'd Sympathies and Antipathies whereby one Man more than another is not only disposed but even by secret impuls forced to affect or dislike such or such a person or thing without any manifest cause or inducement so to do Of Sympathies betwixt Persons there is great variety of Examples especialy in Lovers among whom many are not allured by that grand bait of the Sensitive Soul Beauty but strongly attracted and as it were fascinated by they know not what hidden Congruity or as the French call it agreeableness of Spirits which enchains them so firmly to the persons beloved that notwithstanding the deformities they see and acknowledge to be in them yea and the contempt they somtimes receive from them they still doat upon and with delightful submissions court and adore them And as for Antipathies as well toward Persons as things instances of them also are without number and many shew themselves at our very table Where one Man abhors a brest of Mutton yet loves the Shoulder cut from it a second swoons at the sight of Eels and yet will feast upon Lampreys or Congers a third abominates Chees but is pleased with Milk a fourth devests rosted Pigg yet can make a meal upon bacon This Man sweats at presence of a Cat that falls into an agony by casting his eye upon a Frogg or Toad an other can never be reconciled to Oysters Nay more there are who feel themselves ready to faint if a Cat be hidden in some secret place of the room wherein they are though they suspect no such encountre of their natural enemy till they are wounded with the invisible darts or emanations from her body And all these admirable Effects proceed not from any positive Evil or malignity in the things abhorred for what 's one Mans meat is an others poyson but only from their incongruity or occult Enmity to this or that particular Sensitive Soul For if at any time it happens that the consistence of Animal Spirits that constitute the lucid or Sensitive part of this Soul be by the encountre of any object put into great disorder she ever after abhors the approach or effâ—luvia of the same Whereas the Congruity of particles proceeding from an object to the contexture of the Soul is on the contrary the ground of all her secret Amities 2. Passions Metaphysical or which seem to have their first rise from and principaly to relate to the Rational Soul are those which Divines call devout and religious Affections directed to objects Supernatural and chiefly to God For when our nobler Soul reflecting upon the excellency and immortality of her nature aspires by sublime speculations toward her supreme felicity the contemplation and love of her Creator and determines her Will to persue that incomprehensible because infinite subject of all perfections which alone can satisfy her understanding with light or knowledge and her will with love she doth not only exercise herself in simple and abstracted conceptions such as are proper to her immaterial essence alone and conformable to the dignity of the thing she speculates but communicates her affects also to the Sensitive Soul by whose subordinate motions she is obliged to act respectively to her end And these motions or acts being thus traduced from the superiour to the inferior Soul and thence derived first to the brain and imagination then to the heart produce therein and so in the blood the various motions that constitute such Passions as we observe in our selves when we are most ardently urged to acts of devotion and piety toward the supream Being Whence it is doubtless that Divine love detestation of sin repentance hope of Salvation fear of incensing Divine justice and most if not all other acts or passions of devotion are commonly ascribed to the heart and that not without some reason For though I cannot admit the heart to be the Seat of the Passions as the Aristoteleans unanimously hold it to be only because of the sensible alterations therein produced in most passions since in truth those alterations are rather consequents than causes of Passions and since they are not felt by us as in the heart but only by means of the nerves descending thither from the brain as pain is not felt as in the foot but by intervention of nerves betwixt the foot and the brain and as the starrs appear to us as in heaven by mediation of their light affecting our Optick nerves So that it is no more necessary the Soul should exercise her functions or receive her passions immediately in the heart only because she feels her passions therein than it is she should be in heaven because she sees the starrs to be there or in the foot because pain appears to her to be there Notwithstanding this I say yet the adscription of these devout Passions to the heart is not altogether destitute of reason For for instance when the inferiour Soul is commanded by the Superior to humble and as it were to prostrate herself in adoration of the sacred Majesty of God instantly both parts thereof as well the Sensitive as the Vital are forced to repress and restrain their wonted emanations or effusions Whereupon the Animal Spirits being in whole legions withdrawn from minis tring to the Imagination and Senses are by the nerves transmitted in crowds to the heart which while they closely contract and shut they cause the blood to remain longer than is usual in the cavities thereof and by that means keep it both from being too much kindled in the Lungs and from being sent from the heart in too great abundance into the rest of the body and more especialy into the brain as if Nature itself had instituted that in sacred passions the blood or principal seat of life should be offered up to the Author of life upon the altar of the heart while the brain or seat of reason is kept serene and clear Nor is it difficult to a man praying to Almighty God with fervency of Spirit to observe in himself that his blood is more and more arrested and detained within his breast the while insomuch that his heart seems to swell his lungs to be opprest and he is forced frequently to interrupt his oraisons with profound sighs for attraction of fresh aer as if the reasonable Soul not content to devote herself alone and pour forth her holy desires to God laboured to make a libation also of the vital blood for a propitiatory oblation So that though the Soul cannot in strictness of truth be said to receive her passions in the heart yet since the alterations caused in us by them are greater and more sensible in the heart and consequently in the blood than in any other part of the whole body beside I am not so addicted to vitilitigation as to contend about
point of temperament and as this or that of the usual concomitants of it is more powerful than the rest so must the Effects thereof upon the body be likewise various And from this variety men have taken notice chiefly of two sorts of Anger One that is quickly kindled violent at first and discovers it self visibly by outward signs but performs little and may be easily composed And to this they are most obnoxious who are good-natur'd i.e. who are inclined to goodness and love For it ariseth not from profound Hatred but from a sudden Aversion surprising them because being propens to conceive that all things ought to proceed in that manner which they judge to be the best whenever they see others to act otherwise first they admire and then are offended and so what would be to others matter only of Indignation to them proves cause of Anger But this commotion is soon calmed because the force of the sudain Aversion that raised it continues not long and so soon as they perceive that the thing for which they were offended ought not to have commoved them to passion they suppress their displeasure and repent of it The Other that wherein Hatred and Grief are predominant and which though at first it hardly betray it self by external signs unless by the suddain paleness of the countenance and trembling is notwithstanding more impetuous within secretly gnaws the very heart and produceth dangerous effects And to this pernicious sort of Anger they are most subject who have prouâ— cowardly and weak Souls For so much the greater doe injuries appear by how much the better opinion pride makes Men to have of themselves yea and by how much greater value is put upon the things which the injuries take away and these things are alwaies so much the more valued by how much the more weak and abject the Soul is because they depend upon others but the Generous put little value upon any thing that is not dependent upon themselves When we consider what opinion other Men have of Us the Good which we believe to be in us disposeth us to Glory which seems to be composed of Self-estimation and Ioy for to see ourselves well esteemed by others gives us cause to have a good esteem for ourselves and on the contrary the Evil we are conscious of forceth us to Shame which is a sort of Modesty or Humility and Self-diffidence for as we have formerly observed who thinks himself above Contempt will hardly be humbled to shame These two Passions Glory and Shame tho directly opposite each to other doe yet agree in their End which is to incite us to Virtue the first by hope the other by fear and that we may make a right use of them both we are to have our judgment well instructed what actions are truely worthy praise or dispraise lest otherwise we be ashamed of virtuous actions or affect glory from vices as it happeneth to too great a part of mankind Thus have we at length recounted all the Passions of this our fifth division and deduced them successively from their several causes or occasions in that order wherein their most remarkable diversity seemd to us most easily distinguishable But now because some of these passions are simple others Composed and that to our more clear understanding of the nature of both sorts it is necessary to enquire more profoundly into the Motions of the Sensitive Soul and spirits that constitute their Essential Differences it remains that we yeeld obedience to that necessity so far forth at least as to explain the Motions proper to that couplet of more simple affections Ioy and Grief the two points in which all human actions end and to that most violent one Anger In Ioy therefore which is a delightful commotion of the Sensitive Soul as it were triumphing in her fruition of good or pleasure I conceive that the Animal spirits being in great abundance but with a placid and equal motion sent by the nerves to the heart cause the orifices thereof to be opened and dilated more than at other times and so the blood to be imported and exported more copiously and freely and that by this means from the blood are brought into the brain a plentious supply of new spirits which extracted out of the purest and most refined parts of the blood are most fit to confirm the idea formed of the present good in the imagination and so to continue the Soul in her pleasant Emotion Hence probably it is that in this most agreeable passion both the pulse is alwaies made equal and more frequent tho not so intense and strong as in Love and a certain gratefull heat is felt not only through the Lungs and all the breast but through all outward parts of the body from the diffusion of the blood in full streams into them which is discernible even by the florid purple colour wherewith they are suddainly tinged and by the inflation or plumpness of all the muscles of the face which is thereby rendered more serene sweet and cheerful Easy therefore it is to infer that as this passion is most congruous to the nature of the Corporeal Soul so are the corporeal motions that accompany and characterize it most profitable to health provided they be moderare For this Commotion and Effusion may be so vehement and suddain that the Soul may become weak and unable to rule the body or to actuate the organs of speech yea swooning and death itself somtimes follow profuse and insolent Joy So Lacon Chilo an eminent Philosopher suddainly expired in excessive joy beholding his Sonne a Victor in the Olympic games So Sophocles the Tragedian also and Dionysius the Tyrant died of a surfet of suddain Joy The reason whereof seems to consist not in a vehement effusion and dissipation of the vital spirits and a destitution of the Heart consequent thereunto as Fernelius would have it because the faster the blood is effused through the arteries from the heart the swifter must it return to the heart through the veines so that the heart cannot be totaly exhausted and left destitute of blood but rather in a surcharge and suffocation of the heart by too redundant an afflux of blood For upon extraordinary dilatation of the floud-gates of the heart by immoderate joy the current of blood both out of the Vena cava and from the arteria venosa may pour itself with so much violence and in so great a quantity into the ventricles thereof that the heart unable to discharge itself soon enough of that oppressing deluge by retruding its valves may be suffocated its motions stopped and the Vital Flame in a moment extinguished For certain it is that in the state of health the blood is not admitted into the heart beyond a certain proportion nor can that proportion be much exceeded whatever the cause be that maketh an apertio portarum there without manifest danger of life Among the Signs of this delightful passion
some have given the upper hand to that distortion of the countenance accompanied with a loud but inarticulate voice which we call Laughter but this being neither proper to nor inseparable from Ioy cannot therefore belong to it essentialy That it is frequently a concomitant of Mirth or Hilarity is not to be disputed but Mirth is the lowest degree of Joy a light and superficial emotion of the Sensitive Soul and Spirits a kind of short tickling of the Imagination usualy expressed by Laughter whereas Ioy is serious profound and grave according to that memorable Sentence of Seneca epist. 23. res severa est verum gaudium Laughter then as I said is not proper to all Joy because common to some other affections for some are observed to laugh out of Indignation others out of Contempt and disdain neither of which belong to any kind of Joy Nor is it inseparable from Joy because in truth Joy cannot produce Laughter unless when it is very moderate and hath somthing of Admiration or Hate mixt with it For we have it from the oracle of Experience that in great and profound Joy the cause of it whatsoever it be doth never force us to break forth into laughter nay more that we are most easily provoked to laugh when we are sad Whereof the reason seems to be either because in solid Joy the Sensitive Soul is so deeply commoved so intirely taken up with the delight of fruition that she cannot attend to shake the Midriff Lungs and Muscles of the breast nimbly and strongly enough to create laughter or because at that time the Lungs are so distended with blood that they cannot by repeted concussions or alternate contractions and relaxations be further inflated with air whereof no little quantity is required to produce that loud sound emitted in Laughter That we may understand this matter more fully let us examine the cause or occasion and the Motions of Laughter As for the First viz. the Occasion or Motive whatsoever it be there must concur therein these three Conditions following 1. it must be new and surprising because whatsoever is ridiculous at first ceaseth to be so when grown stale 2. it must be such a novelty as may suggest to us a conception of some eminency or advantage in our selves above another whom the occasion chiefly concerns for why are we naturally prone to laugh at either a jest which is nothing but a witty or elegant discovery and representation of some absurdity or indecency of another abstracted from his person or at the mischances and infirmities of others unless from hence that thereby our own abilities are the more set off and illustrated and recommended to us by way of comparison 3. It must not touch our own or our friends honour for in that point we are too tender to tolerate much less to laugh at a jest broken upon our selves or friends of whose dishonour we participate These requisites in a ridiculous cause considered we may adventure to conclude that Laughter is an effect of sudden but light Joy arising from the unexpected discovery of some infirmity in another not our friend and from imagination of our own eminency and exemption from the like Here then you see is something of Admiration from the Novelty something of Aversion from the Infirmity something of Ioy or triumph from our opinion of some eminency in our selves And as for that Laughter which is sometimes joyned with Indignation it is most commonly fictitious or artificial and then it depends intirely upon our will as a voluntary action but when 't is true or Natural it seems likewise to arise from Ioy conceived from hence that we see our selves to be above offence by that evil which is the cause or subject of our indignation and that we feel our selves surprised by the unexpected novelty of the same So that to the production of this Laughter also is required a concurs of Ioy Aversion and Admiration but all moderate If this be so what then shall we think of that odd example of Laughter in Ludovicus vives who writes of himself lib. 3. de Anima cap. de Risu that usually when he began to eat after long fasting he could not forbear to break forth into a fit of loud laughter This doubtless was not voluntary because he strove to suppress it nor could it be Convulsive such as Physicians call Risus Sardonius because he was in perfect health sensible of no pain therein nor incommodity thereupon It must therefore be Natural though not Passionate proceeding from some cause very obscure and idiosyncritical that is peculiar to his constitution perhaps this that in this Learned man either the Lungs were more apt to be distended with blood or the Midriff more easily put into the motions that produce laughter than commonly they are in most other men The First because in general whatsoever causeth the Lungs to be suddenly puffed up and distended with blood causeth also the external action of Laughter unless where sorrow changeth that action into groaning and weeping the other because all Laughter is made chiefly by quick and short vibrations of the Midriff But this rare Phenomenon we shall perhaps be better able to solve when we have considered how the action of Laughter is performed in all other men Concerning this Problem therefore it is observable that in Man there seems to be a greater consent or sympathy or rather commerce of motions betwixt the Midriff and the Heart yea and the Imagination also than in Brutes of what order or tribe soever and that the Reason given hereof by the most accurate of our Modern Anatomists is this that the principal Nerve of the Midriff is rooted in the same Nerve of the Spine named Nervus vertebralis from whence there comes a conspicuous branch into the grand plexus of the Intercostal nerve and that commonly two sometimes three other branches more are derived from that same notable plexus into the very trunk of the Nerve of the Diaphragm as you may see most elegantly represented by Dr. Willis in the 9 th Table of his most elaborate Book de Anatomia Cerebri which are not found in Beasts For from this plenty and singular contexture of nerves it may be conjectured not only why the Diaphragm doth so readily conform its motions to those of the Praecordia and of the Animal Spirits excited in passions of the Mind and cooperate with them but also why Risibility is an affection proper only to Man For as the same most curious Dr. Willis reasoneth in his chapter of the functions and uses of the Intercostal pair of nerves when the Imagination is affected with some pleasant and new conceipt instantly there is caused a brisk and placid motion of the heart as if it sprung up with joy to be alleviated or eased of its burden Wherefore that the blood may be the more speedily discharged out of the right Ventricle of the heart into the Lungs and out
of the left into the Aorta or grand Artery the Diaphragm being by abundance of Animal spirits immitted through so many nerves proceeding from the aforesaid Plexus briskly agitated is by nimble contraction drawn upwards and so making many vibrations doth at once raise up the Lungs and force them to expell the blood out of their vessels into the arteria venosa and to explode the aire out of their pipes into the windpipe and this by frequent contractions of their lax and spongy substance answerable in time and quickness to the vibrations of the Midriff And then because the same Intercostal nerve which communicateth with the nerve of the Diaphragm below is conjoyned above also with the nerves of the jaws and muscles of the face thence it is that the motions of Laughter being once begun in the brest the face also is distorted into gestures or grimasces patheticaly correspondent thereunto And this is the most probable account I am able at present to give of the occasions and motions of passionate Laughter in general nor can I at present think of any more plausible conjecture concerning the reason of the admirable laughter of Ludovicus Vives than this that in him the nerves inservient to the motion of the Midriff might be after such a peculiar manner contrived and framed as easily to cause quick and short reciprocations thereof upon the pleasant affection of his Imagination by the grateful relish of his meat after long abstinence which doth alwaies highten the pleasure of refection But we have insisted too long upon the motions of Ioy. In the contrary whereof viz. Grief or Sorrow which we have above described to be an ingrateful languor of the Soul from a conception of evil present moving her to contract herself that she may avoid it the Animal Spirits are indeed recalled inward but slowly and without violence so that the blood being by degrees destitute of a sufficient influx of them is trasmitted through the heart with too slow a motion Whence the pulse is rendered little slow rare and weak and there is felt about the heart a certain oppressive strictness as if the orifices of it were drawn together with a manifest chilness congealing the blood and communicating itself to the rest of the body From which dejecting symptoms it is easy to collect that this dolefull affection especialy if it be vehement and of long continuance cannot but infer many and grievous incommodities to the whole body For besides this that it darkneth the spirits and so dulls the wit obscures the judgment blunts the memory and in a word beclouds the Lucid part of the Soul it doth moreover incrassate the blood by refrigeration and by that reason immoderately constringe the heart cause the lamp of life to burn weakly and dimly induce want of sleep by drying the brain corrupt the nutritive juice and convert it into that Devil of a humor Melancholy No wonder then if in men overcome with this so dismal passion the countenance appears pale wan and liveless the limbs grow heavy and indisposed to motion the flesh decays and consumes through want of nourishment and the whole body be precipated into imbecillity Cachexy or an evil habit languishing and other cold and chronic diseases All which the wisest of Men King Salomon hath summ'd up in few words in 17 Chap. of his Proverbs where he advertiseth that a sorrowful spirit drieth up the very bones And yet notwithstanding it is very rarely found that from Grief either long and obstinate or violent and suddainly invading any man hath fallen into a swoon or been suddenly extinguished Which I am apt to refer to this that in the ventricles of the heart tho but very slowly commoved there can hardly be so smale a quantity of blood but it may suffice to keep alive the vital flame burning therein when the orifices of them are almost closed as commonly they are by immoderate grief Somtimes this bitter passion is signified by a certain uncomely distortion of the face somwhat different from that of Laughter and acompanied with Tears somtimes only by Sighs by Sighs when the Grief is extreme by Tears when it is but moderate For as Laughter never proceeds from great and profound Joy so neither doe Tears flow from profound sorrow according to that of the Tragedian leves curae loquuntur ingentes stupent Nor is weeping the pathognomonic or infallible sign of Grief For all tears are not voluntary every light hurt or pain of the Eyes causing them to distill against our will nor all voluntary ones the effect of Grief Some weep for sudden joy joyned with Love especialy old men some when their Revenge is suddainly frustrated by the repentance and submission of the offender and such are the tears of Reconciliation Some again weep out of Anger when they meet with a repulse or check of their desires which causing them with regret to reflect upon their own weakness and insufficiency to compass their wills affects them with displeasure and dissolves them into tears as if they fell out with themselves upon a sudden sense of their own defect and this kind of weeping is most familiar to Children and Women when they are crossed in their wills and expectation as also to Revengefull Men upon their beholding of those whom they commisserate and their want of power to help them Notwithstanding the Occasions of weeping be thus various yet since Tears are frequently both an effect and testimony of sorrow the nature and motions whereof we have now attempted to explain it can be no impertinent Digression to inquire further into their original or sours and the manner how they are made to flow when we are willing to signify our present sorrow by shedding them As for the Fountain therefore whence all our Tears flow and the Matter whereof they consist the succesful industry of Modern Anatomists hath discovered that in the Glandules placed at each corner of the Eyes there is either from the blood brought thither by the arteries as the vulgar doctrine is or as I upon good reasons elswhere delivered conceive from the Nutritive juice brought by nerves separated and kept in store a certain thin clear and watery humor partly saline partly subacid in tast the use whereof is aswell to keep the globes of the eyes moist and slippery for their more easy motion as to serve for Tears when we have occasion to shed them And to this some have added that because there are certain branches of nerves like the tendrels of a vine incircling the vessells leading to and from those Glandules and by their tension somtimes constringing them therefore it is probable that when the serous humor is too abundant in the blood brought into the brain the same is by the arteries whose pulse is quickned somwhat by the pressure of these nerves brought more copiously than at other times into those Glandules and after its separation there detained from returning by the veins that
