The System of Nature or the Laws of the Moral and Physical World Volume I Part 4

The source of those errors into which man has fallen, when he has contemplated himself, has its rise, as will presently be shown, in the opinion he has entertained, that he moved by himself--that he always acts by his own natural energy--that in his actions, in the will that gave him impulse, he was independent of the general laws of Nature; and of those objects which, frequently, without his knowledge, always in spite of him, in obedience to these laws, are continually acting upon him. If he had examined himself attentively, he must have acknowledged, that none of the motion he underwent was spontaneous--he must have discovered, that even his birth depended on causes, wholly out of the reach of his own powers--that, it was without his own consent he entered into the system in which he occupies a place--that, from the moment in which he is born, until that in which he dies, he is continually impelled by causes, which, in spite of himself, influence his frame, modify his existence, dispose of his conduct. Would not the slightest reflection have sufficed to prove to him, that the fluids, the solids, of which his body is composed, as well as that concealed mechanism, which he believes to be independent of exterior causes, are, in fact, perpetually under the influence of these causes; that without them he finds himself in a total incapacity to act? Would he not have seen, that his temperament, his const.i.tution, did in no wise depend on himself-- that his pa.s.sions are the necessary consequence of this temperament-- that his will is influenced, his actions determined by these pa.s.sions; consequently by opinions, which he has not given to himself, of which he is not the master? His blood, more or less heated or abundant; his nerves more or less braced, his fibres more or less relaxed, give him dispositions either transitory or durable--are not these, at every moment decisive of his ideas; of his thoughts: of his desires: of his fears: of his motion, whether visible or concealed? The state in which he finds himself, does it not necessarily depend on the air which surrounds him diversely modified; on the various properties of the aliments which nourish him; on the secret combinations that form themselves in his machine, which either preserve its order, or throw it into confusion? In short, had man fairly studied himself, every thing must have convinced him, that in every moment of his duration, he was nothing more than a pa.s.sive instrument in the hands of necessity.

Thus it must appear, that where all is connected, where all the causes are linked one to the other, where the whole forms but one immense chain, there cannot be any independent, any isolated energy; any detached power. It follows then, that Nature, always in action, marks out to man each point of the line he is bound to describe; establishes the route, by which he must travel. It is Nature that elaborates, that combines the elements of which he must be composed;--It is Nature that gives him his being, his tendency, his peculiar mode of action. It is Nature that develops him, expands him, strengthens him, increases his bulk--preserves him for a season, during which he is obliged to fulfil the task imposed on him. It is Nature, that in his journey through life, strews on the road those objects, those events; those adventures, that modify him in a variety of ways, that give him impulses which are sometimes agreeable and beneficial, at others prejudicial and disagreeable. It is Nature, that in giving him feeling, in supplying him with sentiment, has endowed him with capacity to choose, the means to elect those objects, to take those methods that are most conducive, most suitable, most natural, to his conservation. It is Nature, who when he has run his race, when he has finished his career, when he has described the circle marked out for him, conducts him in his turn to his destruction; dissolves the union of his elementary particles, and obliges him to undergo the constant, the universal law; from the operation of which nothing is exempted. It is thus, motion places man in the matrix of his mother; brings him forth out of her womb; sustains him for a season; at length destroys him; obliges him to return into the bosom of Nature; who speedily reproduces him, scattered under an infinity of forms; in which each of his particles run over again, in the same manner, the different stages, as necessary as the whole had before run over those of his preceding existence.

The beings of the human species, as well as all other beings, are susceptible of two sorts of motion: the one, that of the ma.s.s, by which an entire body, or some of its parts, are visibly transferred from one place to another; the other, internal and concealed, of some of which man is sensible, while some takes place without his knowledge, and is not even to be guessed at, but by the effect it outwardly produces. In a machine so extremely complex as man, formed by the combination of such a multiplicity of matter, so diversified in its properties, so different in its proportions, so varied in its modes of action, the motion necessarily becomes of the most complicated kind; its dullness, as well as its rapidity, frequently escapes the observation of those themselves, in whom it takes place.

Let us not, then, be surprised, if, when man would account to himself for his existence, for his manner of acting, finding so many obstacles to encounter, he invented such strange hypotheses to explain the concealed spring of his machine--if then this motion appeared to him, to be different from that of other bodies, he conceived an idea, that he moved and acted in a manner altogether distinct from the other beings in Nature. He clearly perceived that his body, as well as different parts of it, did act; but, frequently, he was unable to discover what brought them into action: from whence he received the impulse: he then conjectured he contained within himself a moving principle distinguished from his machine, which secretly gave an impulse to the springs which set this machine in motion; that moved him by its own natural energy; that consequently he acted according to laws totally distinct from those which regulated the motion of other beings: he was conscious of certain internal motion, which he could not help feeling; but how could he conceive, that this invisible motion was so frequently competent to produce such striking effects? How could he comprehend, that a fugitive idea, an imperceptible act of thought, was so frequently capacitated to bring his whole being into trouble and confusion? He fell into the belief, that he perceived within himself a substance distinguished from that self, endowed with a secret force; in which he supposed existed qualities distinctly differing from those, of either the visible causes that acted on his organs, or those organs themselves. He did not sufficiently understand, that the primitive cause which makes a stone fall, or his arm move, are perhaps as difficult of comprehension, as arduous to be explained, as those internal impulses, of which his thought or his will are the effects. Thus, for want of meditating Nature--of considering her under her true point of view--of remarking the conformity--of noticing the simultaneity, the unity of the motion of this fancied motive-power with that of his body--of his material organs --he conjectured he was not only a distinct being, but that he was set apart, with different energies, from all the other beings in Nature; that he was of a more simple essence having nothing in common with any thing by which he was surrounded; nothing that connected him with all that he beheld.

It is from thence has successively sprung his notions of SPIRITUALITY, IMMATERIALITY, IMMORTALITY; in short, all those vague unmeaning words he has invented by degrees, in order to subtilize and designate the attributes of the unknown power, which he believes he contains within himself; which he conjectures to be the concealed principle of all his visible actions when man once imbibes an idea that he cannot comprehend, he meditates upon it until he has given it a complete personification: Thus he saw, or fancied he saw, the igneous matter pervade every thing; he conjectured that it was the only principle of life and activity; he proceeded to embody it; he gave it his own form; called it JUPITER, and ended by wors.h.i.+pping this image of his own creation, as the power from whom he derived every good he experienced, every evil he sustained. To crown the bold conjectures he ventured to make on this internal motive- power, he supposed, that different from all other beings, even from the body that served to envelope it, it was not bound to undergo dissolution; that such was its perfect simplicity, that it could not be decomposed, nor even change its form; in short, that it was by its essence exempted from those revolutions to which he saw the body subjected, as well as all the compound beings with which Nature is filled.

Thus man, in his own ideas, became double; he looked upon himself as a whole, composed by the inconceivable a.s.semblage of two different, two distinct natures, which have no point of a.n.a.logy between themselves: he distinguished two substances in himself; one evidently submitted to the influence of gross beings, composed of coa.r.s.e inert matter: this he called BODY;--the other, which he supposed to be simple, of a purer essence, was contemplated as acting from itself: giving motion to the body, with which it found itself so miraculously united: this he called SOUL, or SPIRIT; the functions of the one, he denominated _physical, corporeal, material_; the functions of the other he styled _spiritual, intellectual._ Man, considered relatively to the first, was termed the PHYSICAL MAN; viewed with relation to the last, he was designated the MORAL MAN. These distinctions, although adopted by the greater number of the philosophers of the present day, are, nevertheless, only founded on gratuitous suppositions. Man has always believed he remedied his ignorance of things, by inventing words to which he could never attach any true sense or meaning. He imagined he understood matter, its properties, its faculties, its resources, its different combinations, because he had a superficial glimpse of some of its qualities: he has, however, in reality, done nothing more than obscure the faint ideas he has been capacitated to form of this matter, by a.s.sociating it with a substance much less intelligible than itself. It is thus, speculative man, in forming words, in multiplying beings, has only plunged himself into greater difficulties than those he endeavoured to avoid; and thereby placed obstacles to the progress of his knowledge: whenever he has been deficient of facts, he has had recourse to conjecture, which he quickly changed into fancied realities. Thus, his imagination, no longer guided by experience, hurried on by his new ideas, was lost, without hope of return, in the labyrinth of an ideal, of an intellectual world, to which he had himself given birth; it was next to impossible to withdraw him from this delusion, to place him in the right road, of which nothing but experience can furnish him the clue. Nature points out to man, that in himself, as well as in all those objects which act upon him, there is never more than matter endowed with various properties, diversely modified, that acts by reason of these properties: that man is an organized whole, composed of a variety of matter; that like all the other productions of Nature, he follows general and known laws, as well as those laws or modes of action which are peculiar to himself and unknown.

Thus, when it shall be inquired, what is man?

We say, he is a material being, organized after a peculiar manner; conformed to a certain mode of thinking--of feeling; capable of modification in certain modes peculiar to himself--to his organization-- to that particular combination of matter which is found a.s.sembled in him.

If, again, it be asked, what origin we give to beings of the human species?

We reply, that, like all other beings, man is a production of Nature, who resembles them in some respects, and finds himself submitted to the same laws; who differs from them in other respects, and follows particular laws, determined by the diversity of his conformation.

If, then, it be demanded, whence came man?

We answer, our experience on this head does not capacitate us to resolve the question: but that it cannot interest us, as it suffices for us to know that man exists; that he is so const.i.tuted, as to be competent to the effects we witness.

But it will be urged, has man always existed? Has the human species existed from all eternity; or is it only an instantaneous production of Nature? Have there been always men like ourselves? Will there always be such? Have there been, in all times, males and females? Was there a first man, from whom all others are descended? Was the animal anterior to the egg, or did the egg precede the animal? Is this species without beginning? Will it also be without end? The species itself, is it indestructible, or does it pa.s.s away like its individuals? Has man always been what he now is; or has he, before he arrived at the state in which we see him, been obliged to pa.s.s under an infinity of successive developements? Can man at last flatter himself with having arrived at a fixed being, or must the human species again change? If man is the production of Nature, it will perhaps be asked, Is this Nature competent to the production of new beings, to make the old species disappear?

Adopting this supposition, it may be inquired, why Nature does not produce under our own eyes new beings--new species?

It would appear on reviewing these questions, to be perfectly indifferent, as to the stability of the argument we have used, which side was taken; that, for want of experience, hypothesis must settle a curiosity that always endeavours to spring forward beyond the boundaries prescribed to our mind. This granted, the contemplator of Nature will say, that he sees no contradiction, in supposing the human species, such as it is at the present day, was either produced in the course of time, or from all eternity: he will not perceive any advantage that can arise from supposing that it has arrived by different stages, or successive developements, to that state in which it is actually found. Matter is eternal, it is necessary, but its forms are evanescent and contingent.

It may be asked of man, is he any thing more than matter combined, of which the former varies every instant?

Notwithstanding, some reflections seem to favor the supposition, to render more probable the hypothesis, that man is a production formed in the course of time; who is peculiar to the globe he inhabits, who is the result of the peculiar laws by which it is directed; who, consequently, can only date his formation as coeval with that of his planet. Existence is essential to the universe, or the total a.s.semblage of matter essentially varied that presents itself to our contemplation; the combinations, the forms, however, are not essential. This granted, although the matter of which the earth is composed has always existed, this earth may not always have had its present form--its actual properties; perhaps it may be a ma.s.s detached in the course of time from some other celestial body;--perhaps it is the result of the spots, or those encrustations which astronomers discover in the sun's disk, which have had the faculty to diffuse themselves over our planetary system;-- perhaps the sphere we inhabit may be an extinguished or a displaced comet, which heretofore occupied some other place in the regions of s.p.a.ce;--which, consequently, was then competent to produce beings very different from those we now behold spread over its surface; seeing that its then position, its nature, must have rendered its productions different from those which at this day it offers to our view.

Whatever may be the supposition adopted, plants, animals, men, can only be regarded as productions inherent in and natural to our globe, in the position and in the circ.u.mstances in which it is actually found: these productions it would be reasonable to infer would be changed, if this globe by any revolution should happen to s.h.i.+ft its situation. What appears to strengthen this hypothesis, is, that on our ball itself, all the productions vary, by reason of its different climates: men, animals, vegetables, minerals, are not the same on every part of it: they vary sometimes in a very sensible manner, at very inconsiderable distances.

The elephant is indigenous to, or native of the torrid zone: the rein deer is peculiar to the frozen climates of the North; Indostan is the womb that matures the diamond; we do not find it produced in our own country: the pine-apple grows in the common atmosphere of America; in our climate it is never produced in the open ground, never until art has furnished a sun a.n.a.logous to that which it requires--the European in his own climate finds not this delicious fruit. Man in different climates varies in his colour, in his size, in his conformation, in his powers, in his industry, in his courage, and in the faculties of his mind. But, what is it that const.i.tutes climate? It is the different position of parts of the same globe, relatively to the sun; positions that suffice to make a sensible variety in its productions.

There is, then, sufficient foundation to conjecture that if by any accident our globe should become displaced, all its productions would of necessity be changed; seeing that causes being no longer the same, or no longer acting after the same manner, the effects would necessarily no longer be what they now are, all productions, that they may be able to conserve themselves, or maintain their actual existence, have occasion to co-order themselves with the whole from which they have emanated.

Without this they would no longer be in a capacity to subsist: it is this faculty of co-ordering themselves,--this relative adaption, which is called the ORDER OF THE UNIVERSE: the want of it is called CONFUSION.

Those productions which are treated as MONSTROUS, are such as are unable to co-order themselves with the general or particular laws of the beings who surround them, or with the whole in which they find themselves placed: they have had the faculty in their formation to accommodate themselves to these laws; but these very laws are opposed to their perfection: for this reason they are unable to subsist. It is thus that by a certain a.n.a.logy of conformation, which exists between animals of different species, mules are easily produced; but these mules, unable to co-order themselves with the beings that surround them, are not able to reach perfection, consequently cannot propagate their species. Man can live only in air, fish only in water: put the man into the water, the fish into the air, not being able to co-order themselves with the fluids which surround them, these animals will quickly be destroyed. Transport by imagination, a man from our planet into SATURN, his lungs will presently be rent by an atmosphere too rarified for his mode of being, his members will be frozen with the intensity of the cold; he will perish for want of finding elements a.n.a.logous to his actual existence: transport another into MERCURY, the excess of heat, beyond what his mode of existence can bear, will quickly destroy him.

Thus, every thing seems to authorise the conjecture, that the human species is a production peculiar to our sphere, in the position in which it is found: that when this position may happen to change, the human species will, of consequence, either be changed or will be obliged to disappear; seeing that there would not then be that with which man could co-order himself with the whole, or connect himself with that which can enable him to subsist. It is this apt.i.tude in man to co-order himself with the whole, that not only furnishes him with the idea of order, but also makes him exclaim "_whatever is, is right_;" whilst every thing is only that which it can be, as long as the whole is necessarily what it is; whilst it is positively neither good nor bad, as we understand those terms: it is only requisite to displace a man, to make him accuse the universe of confusion.

These reflections would appear to contradict the ideas of those, who are willing to conjecture that the other planets, like our own, are inhabited by beings resembling ourselves. But if the LAPLANDER differs in so marked a manner from the HOTTENTOT, what difference ought we not rationally to suppose between an inhabitant of our planet and one of SATURN or of VENUS?

However it may be, if we are obliged to recur by imagination to the origin of things, to the infancy of the human species, we may say that it is probable that man was a necessary consequence of the disentangling of our globe; or one of the results of the qualities, of the properties, of the energies, of which it is susceptible in its present position-- that he was born male and female--that his existence is co-ordinate with that of the globe, under its present position--that as long as this co-ordination shall subsist, the human specie will conserve himself, will propagate himself, according to the impulse, after the primitive laws, which he has originally received--that if this co-ordination should happen to cease; if the earth, displaced, should cease to receive the same impulse, the same influence, on the part of those causes which actually act upon it, or which give it energy; that then the human species would change, to make place for new beings, suitable to co-order themselves with the state that should succeed to that which we now see subsist.

In thus supposing the changes in the position of our globe, the primitive man did, perhaps, differ more from the actual man, than the quadruped differs from the insect. Thus man, the same as every thing else that exists on our planet, as well as in all the others, may be regarded as in a state of continual vicissitude: thus the last term of the existence of man is to us as unknown and as indistinct as the first: there is, therefore, no contradiction in the belief that the species vary incessantly--that to us it is as impossible to know what he will become, as to know what he has been.

With respect to those who may ask why Nature does not produce new beings? we may enquire of them in turn, upon what foundation they suppose this fact? What it is that authorizes them to believe this sterility in Nature? Know they if, in the various combinations which she is every instant forming, Nature be not occupied in producing new beings, without the cognizance of these observers? Who has informed them that this Nature is not actually a.s.sembling, in her immense elaboratory, the elements suitable to bring to light, generations entirely new, that will have nothing in common with those of the species at present existing? What absurdity then, or what want of just inference would there be, to imagine that the man, the horse, the fish, the bird, will be no more? Are these animals so indispensably requisite to Nature, that without them she cannot continue her eternal course? Does not all change around us? Do we not ourselves change? Is it not evident that the whole universe has not been, in its anterior eternal duration, rigorously the same that it now is? that it is impossible, in its posterior eternal duration, it can be rigidly in the same state that it now is for a single instant? How, then, pretend to divine that, to which the infinite succession of destruction, of reproduction, of combination, of dissolution, of metamorphosis, of change, of transposition, may be able eventually to conduct it by their consequence? Suns encrust themselves, and are extinguished; planets perish and disperse themselves in the vast plains of air; other suns are kindled, and illumine their systems; new planets form themselves, either to make revolutions round these suns, or to describe new routes; and man, an infinitely small portion of the globe, which is itself but an imperceptible point in the immensity of s.p.a.ce, vainly believes it is for himself this universe is made; foolishly imagines he ought to be the confident of Nature; confidently flatters himself he is eternal: and calls himself KING OF THE UNIVERSE!!!

O man! wilt thou never conceive, that thou art but an ephemeron? All changes in the great macrocosm: nothing remains the same an instant, in the planet thou inhabitest: Nature contains no one constant form, yet thou pretendest thy species can never disappear; that thou shalt be exempted from the universal law, that wills all shall experience change!

Alas! In thy actual being, art not thou submitted to continual alterations? Thou, who in thy folly, arrogantly a.s.sumest to thyself the t.i.tle of KING OF NATURE! Thou, who measurest the earth and the heavens!

Thou, who in thy vanity imaginest, that the whole was made, because thou art intelligent! There requires but a very slight accident, a single atom to be displaced, to make thee perish; to degrade thee; to ravish from thee this intelligence of which thou appearest so proud.

If all the preceding conjectures be refused by those opposed to us; if it be pretended that Nature acts by a certain quantum of immutable and general laws; if it be believed that men, quadrupeds, fish, insects, plants, are from all eternity, and will remain eternally, what they now are: if I say it be contended, that from all eternity the stars have shone, in the immense regions of s.p.a.ce, have illuminated the firmament; if it be insisted, we must no more demand why man is such as he appears, then ask why Nature is such as we behold her, or why the world exists?

We are no longer opposed to such arguments. Whatever may be the system adopted, it will perhaps reply equally well to the difficulties with which our opponents endeavour to embarra.s.s the way: examined closely, it will be perceived they make nothing against those truths, which we have gathered from experience. It is not given to man to know every thing--it is not given him to know his origin--it is not given him to penetrate into the essence of things, nor to recur to first principles--but it is given him, to have reason, to have honesty, to ingenuously allow he is ignorant of that which he cannot know, and not to subst.i.tute unintelligible words, absurd suppositions, for his uncertainty. Thus, we say to those, who to solve difficulties far above their reach, pretend that the human species descended from a first man and a first woman, created diversely according to different creeds;--that we have some ideas of Nature, but that we have none of creation;--that the human mind is incapable of comprehending the period when all was nothing;--that to use words we cannot understand, is only in other terms to acknowledge our ignorance of the powers of Nature;--that we are unable to fathom the means by which she has been capacitated to produce the phenomena we behold.

Let us then conclude, that man has no just, no solid reason to believe himself a privileged being in Nature; because he is subject to the same vicissitudes, as all her other productions. His pretended prerogatives have their foundation in error, arising from mistaken opinions concerning his existence. Let him but elevate himself by his thoughts above the globe he inhabits, he will look upon his own species with the same eyes he does all other beings in Nature: He will then clearly perceive that in the same manner that each tree produces its fruit, by reason of its energies, in consequence of its species: so each man acts by reason of his particular energy; that he produces fruit, actions, works, equally necessary: he will feel that the illusion which he antic.i.p.ates in favour of himself, arises from his being, at one and the same time, a spectator and a part of the universe. He will acknowledge, that the idea of excellence which he attaches to his being, has no other foundation than his own peculiar interest; than the predilection he has in favour of himself--that the doctrine he has broached with such seeming confidence, bottoms itself on a very suspicious foundation, namely IGNORANCE and SELF-LOVE.

CHAP. VII.

_The Soul and the Spiritual System_.

Man, after having gratuitously supposed himself composed of two distinct independent substances, that have no common properties, relatively with each other; has pretended, as we have seen, that that which actuated him interiorly, that motion which is invisible, that impulse which is placed within himself, is essentially different from those which act exteriorly. The first he designated, as we have already said, by the name of a SPIRIT or a SOUL. If however it be asked, what is a spirit?

The moderns will reply, that the whole fruit of their metaphysical researches is limited to learning that this motive-power, which they state to be the spring of man's action, is a substance of an unknown nature; so simple, so indivisible, so deprived of extent, so invisible, so impossible to be discovered by the senses, that its parts cannot be separated, even by abstraction or thought. The question then arises, how can we conceive such a substance, which is only the negation of every thing of which we have a knowledge? How form to ourselves an idea of a substance, void of extent, yet acting on our senses; that is to say, on those organs which are material, which have extent? How can a being without extent be moveable; how put matter in action? How can a substance devoid of parts, correspond successively with different parts of s.p.a.ce? But a very cogent question presents itself on this occasion: if this distinct substance that is said to form one of the component parts of man, be really what it is reported, and if it be not, it is not what it is described; if it be unknown, if it be not pervious to the senses; if it be invisible, by what means did the metaphysicians themselves become acquainted with it? How did they form ideas of a substance, that taking their own account of it, is not, under any of its circ.u.mstances, either directly or by a.n.a.logy, cognizable to the mind of man? If they could positively achieve this, there would no longer be any mystery in Nature: it would be as easy to conceive the time when all was nothing, when all shall have pa.s.sed away, to account for the production of every thing we behold, as to dig in a garden or read a lecture.-- Doubt would vanish from the human species; there could no longer be any difference of opinion, since all must necessarily be of one mind on a subject so accessible to every enquirer.

But it will be replied, the materialist himself admits, the natural philosophers of all ages have admitted, elements and atoms, beings simple and indivisible, of which bodies are composed:--granted; they have no more: they have also admitted that many of these atoms, many of these elements, if not all, are unknown to them: nevertheless, these simple beings, these atoms of the materialist, are not the same thing with the spirit, or the soul of the metaphysician. When the natural philosopher talks of atoms--when he describes them as simple beings, he indicates nothing more than that they are h.o.m.ogeneous, pure, without mixture: but then he allows that they have extent, consequently parts, are separable by thought, although no other natural agent with which he is acquainted is capable of dividing them: that the simple beings of this genus are susceptible of motion--can impart action--receive impulse--are material--are placed in Nature--are indestructible;--that consequently, if he cannot know them from themselves, he can form some idea of them by a.n.a.logy: thus he has done that intelligibly, which the metaphysician would do unintelligibly: the latter, with a view to render man immortal, finding difficulties to his wish, from seeing that the body decayed--that it has submitted to the great, the universal law-- has, to solve the difficulty, to remove the impediment, given him a soul, distinct from the body, which he says is exempted from the action of the general law: to account for this, he has called it a spiritual being, whose properties are the negation of all known properties, consequently inconceivable: had he, however, had recourse to the atoms of the former--had he made this substance the last possible term of the division of matter--it would at least have been intelligible; it would also have been immortal, since, according to the reasonings of all men, whether metaphysicians, theologians, or natural philosophers, an atom is an indestructible element, that must exist to all eternity.

All men are agreed in this position, that motion is the successive change of the relations of one body with other bodies, or with the different parts of s.p.a.ce. If that which is called _spirit_ be susceptible of communicating or receiving motion--if it acts--if it gives play to the organs of body--to produce these effects, it necessarily follows that this being changes successively its relation, its tendency, its correspondence, the position of its parts, either relatively to the different points of s.p.a.ce, or to the different organs of the body which it puts in action: but to change its relation with s.p.a.ce, with the organs to which it gives impulse, it follows of necessity that this spirit most have extent, solidity, consequently distinct parts: whenever a substance possesses these qualities, it is what we call MATTER, it can no longer be regarded as a simple pure being, in the sense attached to it by the moderns, or by theologians.

Thus it will be seen, that those who, to conquer insurmountable difficulties, have supposed in man an immaterial substance, distinguished from his body, have not thoroughly understood themselves; indeed they have done nothing more than imagined a negative quality, of which they cannot have any correct idea: matter alone is capable of acting on our senses; without this action nothing would be capable of making itself known to us. They have not seen that a being without extent is neither in a capacity to move itself, nor has the capability of communicating motion to the body; since such a being, having no parts, has not the faculty of changing its relation, or its distance, relatively to other bodies, nor of exciting motion in the human body, which is itself material. That which is called our soul moves itself with us; now motion is a property of matter--this soul gives impulse to the arm; the arm, moved by it, makes an impression, a blow, that follows the general law of motion: in this case, the force remaining the same, if the ma.s.s was two-fold, the blow should be double. This soul again evinces its materiality in the invincible obstacles it encounters on the part of the body. If the arm be moved by its impulse when nothing opposes it, yet this arm can no longer move, when it is charged with a weight beyond its strength. Here then is a ma.s.s of matter that annihilates the impulse given by a spiritual cause, which spiritual cause having no a.n.a.logy with matter, ought not to find more difficulty in moving the whole world, than in moving a single atom, nor an atom, than the universe. From this, it is fair to conclude, such a substance is a chimera--a being of the imagination. That it required a being differently endowed, differently const.i.tuted, to set matter in motion-- to create all the phenomena we behold: nevertheless, it is a being the metaphysicians have made the contriver, the Author of Nature. As man, in all his speculations, takes himself for the model, he no sooner imagined a spirit within himself, than giving it extent, he made it universal; then ascribed to it all those causes with which his ignorance prevents him from becoming acquainted, thus he identified himself with the Author of Nature--then availed himself of the supposition to explain the connection of the soul with the body: his self-complacency prevented his perceiving that he was only enlarging the circle of his errors, by pretending to understand that which it is more than possible he will never be permitted to know; his self-love prevented him from feeling, that whenever he punished another for not thinking as he did, that he committed the greatest injustice, unless he was satisfactorily able to prove that other wrong, and himself right: that if he himself was obliged to have recourse to hypothesis--to gratuitous suppositions, whereon to found his doctrine, that from the very fallibility of his nature, these might be erroneous: thus GALLILEO was persecuted, because the metaphysicians, the theologians of his day, chose to make others believe what it was evident they did not themselves understand.

As soon as I feel an impulse, or experience motion, I am under the necessity to acknowledge extent, solidity, density, impenetrability in the substance I see move, or from which I receive impulse: thus, when action is attributed to any cause whatever, I am obliged to consider it MATERIAL. I may be ignorant of its individual nature, of its mode of action, or of its generic properties; but I cannot deceive myself in general properties, which are common to all matter: this ignorance will only be increased, when I shall take that for granted of a being, of which from that moment I am precluded by what I admit from forming any idea, which moreover deprives it completely either of the faculty of moving itself, giving an impulse, or acting. Thus, according to the received idea of the term, a spiritual substance that moves itself, that gives motion to matter, and that acts, implies a contradiction, that necessarily infers a total impossibility.

The partizans of spirituality believe they answer the difficulties they have acc.u.mulated, by a.s.serting that "_the soul is entire--is whole under each point of its extent_." If an absurd answer will solve difficulties, they certainly have done it. But let us examine this reply:--it will be found that this indivisible part which is called soul, however insensible or however minute, must yet remain something: then an infinity of unextended substances, or the same substance having no dimensions, repeated an infinity of times, would const.i.tute a substance that has extent: this cannot be what they mean, because according to this principle, the human soul would then be as infinite as the Author of Nature; seeing that they have stated this to be a being without extent, who is an infinity of times whole in each part of the universe.

But when there shall appear as much solidity in the answer as there is a want of it, it must be acknowledged that in whatever manner the spirit or the soul finds itself in its extent, when the body moves forward the soul does not remain behind; if so, it has a quality in common with the body, peculiar to matter; since it is conveyed from place to place jointly with the body. Thus, when even the soul should be admitted to be immaterial, what conclusion must be drawn? Entirely submitted to the motion of the body, without this body it would remain dead and inert.

This soul would only be part of a two-fold machine, necessarily impelled forward by a concatenation, or connection with the whole. It would resemble a bird, which a child conducts at its pleasure, by the string with which it is bound.

Thus, it is for want of consulting experience, by not attending to reason, that man has darkened his ideas upon the concealed principle of his motion. If, disentangled from prejudice--if, dest.i.tute of gratuitous suppositions--if, throwing aside error, he would contemplate his soul, or the moving principle that acts within him, he would be convinced that it forms a part of its body, that it cannot be distinguished from it, but by abstraction; that it is only the body itself, considered relatively with some of its functions, or with those faculties of which its nature, or its peculiar organization, renders it susceptible:--he will perceive that this soul is obliged to undergo the same changes as the body; that it is born with it; that it expands itself with it; that like the body, it pa.s.ses through a state of infancy, a period of weakness, a season of inexperience; that it enlarges itself, that it strengthens itself, in the same progression; that like the body, it arrives at an adult age or reaches maturity; that it is then, and not till then, it obtains the faculty of fulfilling certain functions; that it is in this stage, and in no other, that it enjoys reason; that it displays more or less wit, judgment, and manly activity; that like the body, it is subject to those vicissitudes which exterior causes obliges it to undergo by their influence; that, conjointly with the body, it suffers, enjoys, partakes of its pleasures, shares its pains, is sound when the body is healthy, and diseased when the body is oppressed with sickness; that like the body, it is continually modified by the different degrees of density in the atmosphere; by the variety of the seasons, and by the various properties of the aliments received into the stomach: in short, he would be obliged to acknowledge that at some periods it manifests visible signs of torpor, stupefaction, decrepitude, and death.

In despite of this a.n.a.logy, or rather this continual ident.i.ty, of the soul with the body, man has been desirous of distinguis.h.i.+ng their essence; he has therefore made the soul an inconceivable being: but in order that he might form to himself some idea of it, he was, notwithstanding, obliged to have recourse to material beings, and to their manner of acting. The word _spirit_, therefore, presents to the mind no other ideas than those of breathing, of respiration, of wind.

Thus, when it is said the _soul is a spirit_, it really means nothing more than that its mode of action is like that of breathing: which though invisible in itself, or acting without being seen, nevertheless produces very visible effects. But breath, it is acknowledged, is a material cause; it is allowed to be air modified; it is not, therefore, a simple or pure substance, such as the moderns designate under the name of SPIRIT.

It is rather singular that in the Hebrew, the Greek, and the Latin, the synonymy, or corresponding term for spirit should signify _breath_. The metaphysicians themselves can best say why they have adopted such a word, to designate the substance they have distinguished from matter: some of them, fearful they should not have distinct beings enough, have gone farther, and compounded man of three substances, BODY, SOUL, and INTELLECT.

Although the word _spirit_ is so very ancient among men, the sense attached to it by the moderns is quite new: the idea of spirituality, as admitted at this day, is a recent production of the imagination. Neither PYTHAGORAS nor PLATO, however heated their brain, however decided their taste for the marvellous, appear to have understood by spirit an immaterial substance, or one without extent, devoid of parts; such as that of which the moderns have formed the human soul, the concealed author of motion. The ancients, by the word spirit, were desirous to define matter of an extreme subtilty, of a purer quality than that which acted grossly on our senses. In consequence, some have regarded the soul as an ethereal substance; others as igneous matter; others again have compared it to light. DEMOCRITUS made it consist in motion, consequently gave it a manner of existence. ARISTOXENES, who was himself a musician, made it harmony. ARISTOTLE regarded the soul as the moving faculty, upon which depended the motion of living bodies.

The earliest doctors of Christianity had no other idea of the soul, than that it was material. TERTULLIAN, ARn.o.bIUS, CLEMENT of ALEXANDRIA, ORIGEN, SAINT JUSTIN, IRENAEUS, have all of them discoursed upon it; but have never spoken of it other than as a corporeal substance--as matter.

It was reserved for their successors at a great distance of time, to make the human soul and the soul of the world _pure spirits_; that is to say, immaterial substances, of which it is impossible they could form any accurate idea: by degrees this incomprehensible doctrine of spirituality, conformable without doubt to the views of those who make it a principle to annihilate reason, prevailed over the others: But it might be fairly asked, if the pretended proofs of this doctrine owe themselves to a man, who on a much more comprehensible point has been proved in error; if, on that which time has shewn was accessible to man's reason, the great champion in support of this dogma was deceived; are we not bound to examine, with the most rigorous investigation, the reasonings, the evidence, of one who was the decided, the proven child of enthusiasm and error? Yet DESCARTES, to whose sublime errors the world is indebted for the Newtonian system, although before him the soul had been considered spiritual, was the first who established that, "_that which thinks ought to be distinguished from matter_;" from whence he concludes rather hastily, that the soul, or that which thinks in man, is a spirit; or a simple indivisible substance. Perhaps it would have been more logical, more consistent with reason, to have said, since man, who is matter, who has no idea but of matter, enjoys the faculty of thought, matter can think; that is, it is susceptible of that particular modification called thought.

However this may be, this doctrine was believed divine, supernatural, because it was inconceivable to man. Those who dared believe even that which was believed before; namely, _that the soul was material_, were held as rash inconsiderate madmen, or else treated as enemies to the welfare and happiness of the human race. When man had once renounced experience; when he had abjured his reason; when he had joined the banner of this enthusiastic novelty; he did nothing more, day after day, than subtilize the delirium, the ravings of his imagination: he pleased himself by continually sinking deeper into the most unfathomable depths of error: he felicitated himself on his discoveries; on his pretended knowledge; in an exact ratio as his understanding became enveloped in the mists of darkness, environed with the clouds of ignorance. Thus, in consequence of man's reasoning upon false principles; of having relinquished the evidence of his senses; the moving principle within him, the concealed author of motion, has been made a mere chimera, a mere being of the imagination, because he has divested it of all known properties; because he has attached to it nothing but properties which, from the very nature of his existence, he is incapacitated to comprehend.

The doctrine of spirituality, such as it now exists, offers nothing but vague ideas; or rather is the absense of all ideas. What does it present to the mind, but a substance which possesses nothing of which our senses enable us to have a knowledge? Can it be truth that a man is able to figure to himself a being not material, having neither extent nor parts, which, nevertheless, acts upon matter without having any point of contact, any kind of a.n.a.logy with it; and which itself receives the impulse of matter by means of material organs, which announce to it the presence of other beings? Is it possible to conceive the union of the soul with the body; to comprehend how this material body can bind, enclose, constrain, determine a fugitive being which escapes all our senses? Is it honest, is it plain dealing, to solve these difficulties, by saying there is a mystery in them; that they are the effects of a power, more inconceivable than the human soul; than its mode of acting, however concealed from our view? When to resolve these problems, man is obliged to have recourse to miracles or to make the Divinity interfere, does he not avow his own ignorance? When, notwithstanding the ignorance he is thus obliged to avow by availing himself of the divine agency, he tells us, this immaterial substance, this soul, shall experience the action of the element of fire, which he allows to be material; when he confidently says this soul shall be burnt; shall suffer in purgatory; have we not a right to believe, that either he has a design to deceive us, or else that he does not himself understand that which he is so anxious we should take upon his word?

Let us not then be surprised at those subtile hypotheses, as ingenious as they are unsatisfactory, to which theological prejudice has obliged the most profound modern speculators to recur; when they have undertaken to reconcile the spirituality of the soul, with the physical action of material beings, on this incorporeal substance; its re-action upon these beings; its union with the body. When the human mind permits itself to be guided by authority without proof, to be led forward by enthusiasm; when it renounces the evidence of its senses; what can it do more than sink into error? Let those who doubt this, read the metaphysical romances of LEIBNITZ, DESCARTES, MALEBRANCHE, CUDWORTH, and many others: let them coolly examine the ingenious, but fanciful systems ent.i.tled _the pre-established harmony of occasional causes; physical pre-motion, &c._
