the chief Fibres of all the Muscles which is the Heart that they encompass its Orifices Auricles and Arteries that they spread themselves even in the substance of the Lungs and so by their different motions produce very considerable changes in the Blood For the Nerves which are dispersed through the Fibres of the Heart cause it somerimes to extend and then again to contract with too much force and precipitancy pushing with much violence a great quantity of Blood towards the Head and all the external parts of the Body yet sometimes these Nerves produce an effect directly contrary And the Nerves which encompass the Orifices Auricles and Arteries of the Heart cause very near the same effect with those Spiracles or breathing Holes with which the Chymists moderate the heat of their Furnaces and as the Spouts do which are made use of in Fountains to diminish or encrease the force of the stream For the use of these Nerves is diversly to contract or dilate the Orifices of the Heart and so to hasten or retard the filling and evacuation of the Blood and thereby to augment of diminish its heat Thus the Nerves which are dispersed through the Lungs have also the same use for the Lungs are compos'd only of the branches of the Wind-pipe of the Venous Artery and Arterious Vein interwoven one with another it is visible that the Nerves which are extended throughout the whole substance by contracting of them hinders the Air from passing with so much liberty through the branches of the Wind-pipe and likewise impedes the motion of the Blood through the Venous Artery into the Arterious Vein and so into the Heart Thus these Nerves according to their different agitation still augment and diminish the heat and motion of the Blood In all our Passions we have very sensible Experiments of these different degrees of heat in our Heart Sometimes we feel it manifestly encrease and diminish all of a sudden and as we falsely judge that our Sensations are in the parts of our Bodies and so by that means excite our Soul as it was explained in the first Book so almost all our Philosophers have imagined that the Heart was the principal seat of the Passions of the Soul and this is still the most commonly received Opinion Now because the faculty of Imagining receives great changes by what happens to the Animal Spirits and that the Animal Spirits differ very much according to the different fermentation of the Blood which is made in the Heart it is very easie to discover why passionate Persons imagine things quite after another manner from those who consider them in cold Blood The other Cause which contributes very much either to the augmenting or diminishing these extraordinary fermentations of the Blood in the Heart consists in the action of many other branches of the Nerves which we have already spoke of These branches spread themselves in the Liver II. Of the change of the Spirits caus'd by the Nerves which go to the Liver to the Spleen and the rest of the Bowels which contains the most subtile part of the Blood or what is commonly called the Bile and in the Spleen which contains the more gross or Melancholy in the Pancreas which contains an acid Juice very proper for fermentation In the Stomach Bowels and other parts which contain the Chyle And indeed they are dispersed through every place which can contribute any thing to the varying the fermentation of the Blood in the Heart Also the Arteries and Veins are united to these Nerves as Willis has discovered of the lower Trunk of the great Artery which is ty'd to them near the Heart of the Axillary Artery on the right side the Emulgent Vein and of some others Thus the use of the Nerves being diversly to act those parts to which they are join'd it is easie to conceive how the Nerve which environs the Liver may in contracting it cause a great quantity of Bile to run into the Veins and into the Duct of the Bile which being mingled with the Blood in the Veins and with the Chyle enters into the Heart through the Duct of the Bile and there produces a more violent heat than ordinary Thus when we are mov'd with certain Passions the Blood boils in the Arteries and Veins and this heat spreads it self through the whole Body the Head is inflamed and filled with so great a number of Animal Spirits which being too brisk and too much agitated by their impetuous course hinder the Imagination from representing any other things than those whose Images they form in the Brain that is from thinking of any other Objects besides those of the Passion which Rules It is the same of the little Nerves that go to the Spleen or to other parts which contain a thicker Matter and less susceptible of Heat and Motion it renders the Imagination altogether languishing and dull in causing some gross Matter and such as is difficult to be put in Motion to run into the Blood As for those Nerves which environ the Arteries and Veins their use is to hinder the Blood from passing and by contracting them compel it to run into such places as it finds the freest passage to So that part of the great Artery which supplies all the parts above the Heart with Blood being connected and compressed by these Nerves the Blood must necessarily enter into the Head in great quantities and this way produce a change in the Animal Spirits and by consequence in the Imagination But it must be well observed III. That these Judgments happen without the concurrence of our Will by the order of Providence that all this is performed meerly by Mechanism I mean that all the different Motions of these Nerves in all the different Passions are not produced by the Command of the Will but on the contrary are made without nay even contrary to its Orders So that a Body whose Soul is not so well disposed as that of a healthful Man shall be capable of all the Motions which accompany our Passions Thus even Beasts may have the like altho' they should be only pure Machines And indeed this ought to make us admire the incomprehensible Wisdom of him who hath so well ordered all these Springs that it is sufficient for an Object to move the Optick Nerve after such and such a manner to produce so many different Motions in the Heart the other parts of the Body and even in the Face it self for it hath lately been discovered that the same Nerve which extends some of its branches into the Heart and into the other interior parts also communicates some of its branches to the Eye to the Mouth and to the other parts of the Face So that it cannot raise any Passion within us but it also appears outwardly because there can no motion happen to the branches which go to the Heart but it also communicates it self to some one of those which are dispersed through the Face The

any other Liquors do It gives us the Foil to speak with Plautus and produces many effects in the Mind which are not so advantageous as those that Horace describes in these Verses Quid non ebrietas designat Operta recludit Spes jubet esse ratas in praelia tendit inermes Sollicitis animis onus eximit addocet artes Faecundi Calices quem non fecere disertum Contracta quem non in paupertate solutum It would be easie enough to give a reason of the principal effects that the mingling of the Chyle with the Blood produces in the Animal Spirits and afterwards in the Brain and even in the Soul it self As why Wine rejoyces us and gives a certain Vivacity to the Wit when it is taken with Moderation and for sometime besots Men when 't is drank to Excess From whence proceeds the heaviness after Meals and many other such things for which generally very ridiculous reasons has been given But though we shall not here make a Book of Natural Philosophy yet it will be necessary to give some Idea of the Anatomy of the Brain or make some Suppositions as Mr. D'Cartes has done in his Treatise of Man without which 't will be impossible to explain our selves But if one reads this Treatise of Monsieur D'Cartes with attention we may satisfie our selves upon these questions because he explains all these things or at least gives a sufficient light to discover them as he has done by Meditation provided one has some Knowledge of his PRINCIPLES CHAP. III. That the Air one breaths causes likewise some change in the Spirits THE second general Cause of the changes which happens in the Animal Spirits is the Air we breath for altho' it does immediately make as sensible impressions as the Chyle nevertheless in some time it produces the same effect as the Juice of our Food does presently This Air enters from Branches of the Wind-pipe into that of the Venous Artery and from thence it mingles it self and ferments with the rest of the Blood in the Heart and according to its particular disposition and that of the Blood it produces great changes in the Animal Spirits and by consequence in the faculty of Imagining I know that there are some Persons who do not believe that the Air mingles it self with the Blood in the Lungs and Heart because by their Eyes they cannot discover in the branches of the Wind-pipe and those of the Venous Artery the passages whereby the Air is communicated But we must not confine the Action of the Mind to that of the Senses it can penetrate what is impenetrable by them and apply it self to such things which they cannot 'T is certain that some parts of the Blood continually pass from the branches of the Venous Artery into those of the Wind-pipe as the smell and moistness of the breath sufficiently proves and yet the passages of this communication are imperceptible why therefore cannot the subtile parts of the Air pass from the branches of the Wind-pipe into the Venous Artery altho' the passages of this communication are not so visible In short more humours are evacuated by transpiration from the imperceptible Pores of the Arteries and Skin than by any other passages of the Body and even the Pores of the most solid Metals are not so small but that there are Bodies in Nature small enough to find a free passage for otherwise these Pores would be clos'd up It is true that the Gross and branchy parts of the Air cannot pass through the ordinary Pores of Bodies and that even Water altho' very gross can glide through those passages where this Air is sometime forced to stop But we are not speaking here of those gross and branchy parts of the Air they are it seems unuseful enough for fermentation 't is only of the smallest parts such as are swift and sharp that we speak of and which have none or very small branches to stop them because they are the most proper for the fermentation of the Blood I might nevertheless affirm upon the Relation of Silvius that even the grossest part of the Air pass from the Wind-pipe into the Heart since he assures us that he hath seen it pass thither by the help of M. de Swamerdam for it is more reasonable to believe a Man who says he has seen it than a thousand others who only speak of it by chance It is then certain that the most subtile parts of the Air which we breath enters into our Heart and with the Blood and Chyle maintains there that fire which gives Life and Motion to our Bodies and that according to their different Qualities they produce great changes in the fermentation of the Blood and in the Animal Spirits The truth of this is every day made evident by the divers Humours and different Characters of Persons dispositions that are of different Countries For Example the Gascons have a more lively Imagination than the Normans those of Roan Diep and Picardy differ very much among themselves and that much more from the Lower Normans Nunquid non ultra est sapientia in Teman Jer. c. 49. v. 7. altho' they be very near together But if we consider Men whose Countries are at a greater distance we shall meet with differences still more strange as an Italian and German or a Dutchman In fine there has in all times been some places that have been renowned for the Wisdom of their Inhabitants as Teman and Athens and others for their Stupidity as Thebes Abdera and some others Athenis tenue coelum ex quo acutiores etiam putantur Attici crassum Thebis Cic. de fato Abderitanae pectora plebis habes Mart. Boeotum in crasso jurares aere natum Hor. CHAP. IV. I. Of the Change wrought in the Animal Spirits by the Nerves that go to the Lungs and Heart II. Of that which is caused by the Nerves that pass from the Liver to the Spleen and so into the Bowels III. That all this is done without the assistance of our Will but cannot be effected without a Providence THE third Cause of those changes that happen to the Animal Spirits is the most general and most active of all because it is that which produces maintains and fortifies all the Passions To apprehend which well it 's necessary that we know that the fifth sixth and eighth pair of the Nerves have most of their branches extended through the Breast and Belly where they are very useful for the preservation of the Body but extreamly dangerous to the Soul because the action of these Nerves do not depend upon the Will as those do which serve to move the Arms Legs and other external parts of the Body I. of the change of the Spirits caus'd by the Nerves which go to the Lungs and Heart for they act much more upon the Soul than that does upon them It must therefore be consider'd that many branches of the eight pair of the Nerves cast themselves amongst
