Thus far I have spoken of the influence of our words and actions only upon the material universe, although the principle with which I started includes thoughts also. But are not actions merely the external manifestation of thoughts and purposes? and, therefore, is not thought the efficient agency that impresses the universe? I shall also attempt to show that there are other modes in which the intellect may do this, aside from ordinary words and actions.

But I proceed to the second proof of the general principle. _And I derive it from what may be called optical reactions; that is, the reaction of light and the substances on which it impinges._ These exert such an influence upon it, that, when it is thrown back from them, and enters the organs of vision, or even a transparent lens, with a screen behind it, it produces an image of those objects; in other words, what we call vision.

Now, it is this fact, in connection with the progressive motion of light, that forms the basis of this branch of the argument. Though light moves with such immense velocity, that, for all practical purposes on earth, it is instantaneous, yet, in fact, it does occupy a little more than a second for every two hundred thousand miles which it pa.s.ses over. Hence a flash of lightning occurring on earth would not be visible on the moon till a second and a quarter afterwards; on the sun, till eight minutes; at the planet Jupiter, when at its greatest distance from us, till fifty-two minutes; on Ura.n.u.s, till two hours; on Neptune, till four hours and a quarter; on the star of Vega, of the first magnitude, till forty-five years; on a star of the eighth magnitude, till one hundred and eighty years; and on a star of the twelfth magnitude, till four thousand years; and stars of this magnitude are visible through telescopes; nor can we doubt that, with better instruments, stars of far less magnitude might be seen; so that we may confidently say that this flash of lightning would not reach the remotest heavenly body till more than six thousand years--a period equal to that which has elapsed since man's creation.

Now, suppose that, on these different heavenly bodies, beings exist with organs of vision sufficiently acute to discern a flash of lightning on earth, or, rather, to see all the scenes on that hemisphere of our world that is turned towards them; it is obvious that, on the remotest star, the earth would be seen, at this moment, just coming forth from the Creator's hand, in all the freshness of Eden's glories, with our first parents in the beauty of innocence and happiness, and all the beasts of the field and the fowls of the air playing around them. On a star of the twelfth magnitude would be seen the world as it showed itself four thousand years ago; on a star of the eighth magnitude, as it appeared one hundred and eighty years ago; and so on to the moon, where would be seen the occurrences of the present moment. And since there are ten thousand times ten thousand worlds, scattered through these extremes of distance, is it not clear that, taking them all together, they do at this moment contain a vast panorama of the world's entire history, since the hour when the morning stars sang together, and the sons of G.o.d shouted for joy on creation's morning?

"Thus," says the unknown author of a little work ent.i.tled "The Stars and the Earth," in which these ideas were first developed--"thus the universe encloses the _pictures_ of the past, like an indestructible and incorruptible record, containing the purest and the clearest truth; and as sound propagates itself in the air, wave after wave, or, to take a still clearer example, as thunder and lightning are in reality simultaneous, but in the storm the distant thunder follows at the interval of minutes [seconds?] after the flash, so, in like manner, according to our ideas, the pictures of every occurrence propagate themselves into the distant ether, upon the wings of the ray of light; and although they become weaker and smaller, yet, in immeasurable distance, they still have color and form; and as every thing possessing color and form is visible, so must these pictures also be said to be visible, however impossible it may be for the human eye to perceive it with the hitherto discovered optical instruments."

This last statement of the writer every one will acknowledge is true when applied to G.o.d; for who will doubt that his eye can take in at a glance that universe which he has made? And to do that is to have before him the entire daily history of our globe; nay, probably, also, of every other world. Indeed, such a supposition affords us a lively conception of the divine omniscience, since we have only to suppose this panorama of the indefinite past to extend indefinitely into the future, and the infinite picture will also be present at this moment before the divine mind.

But is the supposition an absurdity, that there may be in the universe created beings, with powers of vision acute enough to take in all these pictures of our world's history, as they make the circuit of the numberless suns and planets that lie embosomed in boundless s.p.a.ce? Suppose such a being at this moment upon a star of the twelfth magnitude, with an eye turned toward the earth. He might see the deluge of Noah, just sweeping over the surface. Advancing to a nearer star, he would see the patriarch Abraham going out, not knowing whither he went. Coming still nearer, the vision of the crucified Redeemer would meet his gaze. Coming nearer still, he might alight upon worlds where all the revolutions and convulsions of modern times would fall upon his eye. Indeed, there are worlds enough and at the right distances, in the vast empyrean, to show him every event in human history.

We may proceed a step farther, and inquire whether such an exaltation of vision as we have supposed may not be hereafter enjoyed by the glorified human mind when it pa.s.ses into the spiritual body. We can hardly believe such a transformation possible. But suppose an individual born blind to grow up to manhood and intelligence without ever having been told any thing about vision. Then suppose the oculist to attempt an operation for the restoration of his sight, and, to prepare him for the transition, let the wonders of human vision be described to him, and he be told that, by a few moments of suffering, he can be put in possession of this astonishing faculty; would it not appear as improbable to him as it now does to us, to imagine that our vision can be so clarified and exalted, that we can discern the events which are pa.s.sing in distant worlds as easily as we now do those immediately around us.

But if such a power of reading human history, from its panorama spread out on the face of the universe, be now possessed by unfallen beings in other spheres, what idea must they form of the character of man? At one time, they must regard the race as given up to hopeless rebellion, and the inflictions of vindictive justice. And then, anon, they would see the sceptre of mercy stretched out, and a few faithful soldiers marching under the banner of virtue and fighting the battles of the Lord. Surely they would need a revelation to understand the anomalies and solve the paradoxes which pa.s.sed under their eyes. They would wonder why a world so filled with tokens of divine goodness, yet so disfigured by wickedness in every form, had not long since been struck from its...o...b..t by the hand of divine justice.

Thus far, in the present argument, I have been following, for the most part, in the track marked out by others. But I now venture to advance into regions. .h.i.therto untrodden for any such purpose; yet I trust that the light which we may find to guide our steps may not prove the bewildering gleam of an _ignis fatuus_, but the lamp of true science.

_My third argument is based upon electric reactions._

Whatever may be the true nature of electricity, it is convenient, and probably leads to no error, to speak of it as a fluid, or rather two fluids. For we find two kinds of electricity, denominated positive and negative; and it is a general fact, that, when a body is brought into one electrical state, it throws other bodies around it into the opposite state, by a power called induction. Those bodies, whose electrical condition has been thus altered, will act on others lying in a remoter circle, and these upon others, and so on, we cannot tell how widely, for we have reason to suppose that electricity is a power that extends through all nature. It can hardly be doubted that is the force which const.i.tutes what we call chemical affinity by which the const.i.tuent parts of all compound bodies are held together; and in those stony and metallic ma.s.ses, that occasionally fall from the heavens, we have proof that this same power holds sway in other worlds; for the most reasonable supposition is, that these meteors move like the planets through the regions of celestial s.p.a.ce, and give us some idea of the const.i.tution of planetary worlds. If so, the same chemical laws, and, of course, the same chemical forces, prevail there as in our planet. Indeed, the uniformity of nature would lead us to such a conclusion were there no facts like those of meteors to teach it directly. It follows, from these principles, that, whenever we change the electrical condition of bodies around us, we start a movement to whose onward march we can a.s.sign no limits but the material universe.

These waves of influence consist of a series of attractions and repulsions, and are independent of the mechanical reactions already considered, which are produced by onward impulses alone.

Now, a change in the electric condition of bodies is produced often by the slightest mechanical, chemical, thermal, physiological, and probably even mental change in man. The usual way of exciting currents of electricity is by friction. But chemical action, as in the galvanic battery, produces a still more energetic and uninterrupted current. The slightest change of temperature, also, may disturb the electric equilibrium perceptibly. It has been of late ascertained, likewise, that a change of physiological condition--that is, a change as to healthy and normal action--affects the electricity of the parts of the system, and consequently of surrounding bodies. Subst.i.tute a man in the place of a galvanic battery, making his two hands the electrodes, and there will go out from him an electric current, that shall sensibly deflect the needle of a galvanometer, an instrument employed for showing the presence of small portions of electricity.

Nay, further, it seems to be most probably established as a fact in science, that a man, in the condition above specified, by a simple act of his will upon his muscles, by which those of one arm only shall be braced, will thereby send an electrical current of one sort through the galvanometer, while a like volition, which shall brace the muscles of the other arm will set in motion an opposite current.

It is also ascertained, that of the two sorts of nerves which supply every muscle, the nerve of sensibility is a positive pole of a Voltaic circuit, while the nerve of motion, or the muscle into which it pa.s.ses, is a negative pole. So that the sensor nerves act as electric telegraphs to carry the sensations to the brain, and inform it what is needed, while the motor nerves bring back the volition to the muscles--the brain acting as a galvanic battery, very much like the electric organs of certain fishes.

From these statements it clearly follows, that, besides the mechanical effects produced by our actions, there is also an electric influence excited and propagated by almost every muscular effort, every chemical change within us, every variation in the state of health, or vigor, and especially by every mental effort; for no thought, probably, can pa.s.s through the mind which does not alter the physiological, chemical, and electric condition of the brain, and consequently of the whole system. The stronger the emotion, the greater the change; so that those great mental efforts, and those great decisions of the will, which bring along important moral effects, do also make the strongest impression upon the material universe. We cannot say how widely, by means of electric force, they reach; but if so subtile a power does, as we have reason to suppose, permeate all s.p.a.ce, and all solid matter, there may be no spot in the whole universe where the knowledge of our most secret thoughts and purposes, as well as our most trivial outward act, may not be transmitted on the lightning's wing; and it may be, that, out of this darkened world, there may not be found any spot where beings do not exist with sensibilities keen enough to learn, through electric changes, what we are doing and thinking.

If there be no absurdity in supposing that even the mechanical influence of our actions may be felt throughout the universe, still less is it absurd to infer the same results from electric agencies.

It would seem, from recent discoveries, that electricity has a more intimate connection with mental operations than any other physical force.

If not identical with the nervous influence, it seems to be employed by the mind to accompany that influence to every part of the system; and the greater the mental excitement, the more energetic the electric movement.

It seems to us a marvellous discovery, which enables man to convey and register his thoughts at the distance of thousands of miles by the electric wires. Should it excite any higher wonder to be told, that, by means of this same power, all our thoughts are transmitted to every part of the universe, and can be read there by the neuter perceptions of other beings as easily as we can read the types or hieroglyphics of the electric telegraph? Yet what a startling thought is it, that the most secret workings of our minds and hearts are momentarily spread out in legible characters over the whole material universe! nay, that they are so woven into the texture of the universe, that they will const.i.tute a part of its web and woof forever! To believe and realize this is difficult; to deny it is to go in the face of physical science. How many things we do believe that are sustained by evidence far less substantial!

_My fourth argument in support of the general principle is based upon odylic reaction._

And what is odylic reaction? What is odyle? you will doubtless inquire.

It is, indeed, a branch of science emphatically new. I know of no account of it, save what appears in a late work, of nearly five hundred pages, by Baron Reichenbach, of Vienna, ent.i.tled "Researches on Magnetism, Electricity, Heat, Light, Crystallization, and Chemical Attraction, in their Relations to the Vital Force," translated by William Gregory, professor of chemistry in the University of Edinburgh. This writer endeavors to show, by a great number of experiments, that there exists in all bodies, and throughout the universe, a peculiar principle, a.n.a.logous to magnetism, electricity, light, and heat, yet distinct from them all, to which he gives the name of _odyle_. It is most manifest in powerful magnets; next in crystals, and exists in the human body, the sun, moon, stars, heat, electricity, chemical action, and, in fact, the whole material universe. Those who are most sensitive to this influence are persons of feeble health, especially somnambulists; but it is found that about one third of individuals, taken promiscuously, and many in good health, are sensible of it; and it was by a series of observations on persons of all cla.s.ses and conditions for years, that the facts have been elicited. The inquiry seems to have been conducted with great fairness and scientific skill, and the author has the confidence of several of the most distinguished scientific men in Europe. If there be no mistake in the results, they promise to explain philosophically many popular superst.i.tions, and also the phenomena of mesmerism, without a resort to superhuman agency, either satanic or angelic. They yield, also, an interesting support to the principle of this lecture. Says Baron Reichenbach, "There is nothing in these observations [which he had just detailed] that, after the contents of the preceding treatises, can much surprise us; but they are certainly a fine additional confirmation of what has been stated in regard to the sun and moon, and also of the fact that the whole material universe, even beyond our earth, acts on us with the very same kind of influence which resides in all terrestrial objects; and lastly, it shows that we stand in a connection of mutual influence, hitherto unsuspected, with the universe; so that, in fact, the stars are not altogether devoid of action on our sublunary, perhaps even on our practical, world, and on the mental processes of some heads."--P. 162.

By the experiments here referred to by this author, he had endeavored to show, that even the light of the stars exerted an odylic influence upon the human system; that is, certain effects independent altogether of their light; and if there be no mistake in the experiments, they certainly do show this. Such a fact almost realizes the suggestions already made, that beings in other spheres may possess such an exaltation of sensibilities as to be able to learn what is going on in this world, and that it is easy to conceive how our sensorium may be raised to the same exalted pitch.

_My fifth argument, ill.u.s.trative of the general principle, is based upon chemical reaction._

Mechanical reaction changes the form and position of bodies; chemical reaction alters their const.i.tution. By the decomposition of some compounds, the elements are obtained for forming others; and such changes are going on around us and within us in great numbers unperceived. In the worlds above us, and in the earth beneath us, from its circ.u.mference to its centre, the trans.m.u.tations of chemistry are in progress, and many of them are modified by the agency of man; so that here is another channel through which human actions exert an influence upon the material universe, and to an extent which we cannot measure. Let us look at some of the modes in which this is done.

Take, in the first place, the facts respecting photography, or the art of obtaining sketches of objects by means of the action of light. This is strictly a chemical process. In a beam of light, that comes to us from the sun, we find not only rays of light and heat, but chemical rays, which act upon some bodies to change their const.i.tution. When these rays are reflected from a human countenance, and fall upon a silvered plate, that has been coated with iodine and bromine, they leave an impression, which is fixed and brought out as a portrait by the vapor of mercury and some other agents. Here the chemical changes produced by these rays are exceedingly perfect; but they produce effects upon many other substances, artificially or naturally prepared; such as paper, for instance, immersed in a solution of bichromate of potash, or upon vegetation, whose green color is probably the result of this action, (as is obvious from the fact that plants growing in the dark are dest.i.tute of color.) Indeed, a large part of the changes of color in nature depend upon these invisible rays.

It seems, then, that this photographic influence pervades all nature; nor can we say where it stops. We do not know but it may imprint upon the world around us our features, as they are modified by various pa.s.sions, and thus fill nature with daguerreotype impressions of all our actions that are performed in daylight. It may be, too, that there are tests by which nature, more skilfully than any human photographist, can bring out and fix those portraits, so that acuter senses than ours shall see them, as on a great canvas, spread over the material universe. Perhaps, too, they may never fade from that canvas, but become specimens in the great picture gallery of eternity.

The thought may perhaps cross some mind, that, though those human actions which are performed in sunlight may be imprinted upon the universe, yet no deed of darkness can thus reveal its author, and remain an eternal stigma upon his name. But there is another phase to this subject. What is the evidence that the chemical rays of a sunbeam are rays of light? We know that they are unequally diffused through the spectrum, being most energetic at its violet extremity; but there is no proof that they are visible. They may, like heat, exert their appropriate influence, which seems to be mainly that of deoxidation, and yet not be colorific. If so, we might expect them to operate in the dark; and experiment proves that they do. An engraving on paper, placed between an iodized silver plate and an amalgamated copper plate, was left in the dark for fifteen hours. On exposing the amalgamated plate to the vapor of mercury, "a very nice impression of the engraving was brought out--it having been effected through the thickness of the paper."--Mr. Hunt, _"On the Changes which Bodies are capable of undergoing in Darkness," Phil. Mag._ vol. xxii. p.

277.--Many like experiments prove the existence; among bodies, of a power a.n.a.logous to, if not identical with, that which accompanies light, and is the basis of the photographic process. Some philosophers do not regard them as identical. But this is of little consequence in my present argument. For all agree that there is a power in nature capable of impressing the outlines of some objects upon others in total darkness.

In respect to such cases, there are one or two facts deserving of special notice. And, first. We must not infer, because man has yet been able to bring out to human view but a few examples of this sort, that they are, therefore, few in nature. Rather should the discovery of a few lead to the conclusion that nature may be full of them, and that a more delicate and refined chemistry may yet disclose them. For the few known cases give us a glimpse of a recondite law of nature, which most likely pervades creation.

Some regard these dark rays as neither light, nor heat, nor chemical rays, but a new element; but, whatever its nature, no reason can be given why it should operate only in a few cases, and those of artificial preparation.

More probably, through this influence, all bodies brought into contact, or proximity, impress their images upon one another; and the time may come, when, touched by a more subtile chemistry than man now wields, these images shall take a place among obvious and permanent things in the universe, to the honor and glory of some, but to the amazement and everlasting contempt of more.

Of more, I say; for wickedness has oftener sought the concealment of darkness than modest virtue. The foulest enormities of human conduct have always striven to cover themselves with the shroud of night. The thief, the counterfeiter, the a.s.sa.s.sin, the robber, the murderer, and the seducer, feel comparatively safe in the midnight darkness, because no human eye can scrutinize their actions. But what if it should turn out that sable night, to speak paradoxically, is an unerring photographist!

What if wicked men, as they open their eyes from the sleep of death, in another world, should find the universe hung round with faithful pictures of their earthly enormities, which they had supposed forever lost in the oblivion of night! What scenes for them to gaze at forever! They may now, indeed, smile incredulously at such a suggestion; but the disclosures of chemistry may well make them tremble. a.n.a.logy does make it a scientific probability that every action of man, however deep the darkness in which it was performed, has imprinted its image upon nature, and that there may be tests which shall draw it into daylight, and make it permanent so long as materialism endures.

There is another chemical principle, called _catalysis_, through which human actions may make powerful and permanent impressions on the universe, and that, too, unperceived by man. In some cases, the mere presence of a certain agent, in a small quant.i.ty, will produce extensive changes of const.i.tution in other bodies, while the agent itself remains unaltered.

Thus a strip of platinum will determine the union of oxygen and hydrogen in the platinum lamp; and sulphuric acid, in a solution of starch, will change it first into gum, and then into sugar; while neither the platinum nor the acid experiences any change. These are called _catalytic_ changes.

More often, however, the catalytic agent is itself in the process of change, and it produces an a.n.a.logous change in other bodies. A familiar example is yeast, or ferment. This substance contains a principle called _diastase_, one part of which is capable of converting two thousand parts of starch into sugar; and this is what is done in the familiar process of fermentation, when we always see verified the scriptural declaration, _A little leaven leaveneth the whole lump._

The precise manner in which the diastase operates in these cases we may not be able to explain. The particles of the diastase, being themselves in motion, possess the power of putting in motion the particles of other bodies; and these, again, operate upon others, and so on, often to an astonishing extent. In the case of the platinum and the acid, however, no change takes place in their molecules, and we can only state it, as an unexplained fact, that they do produce changes in other bodies.

We have other examples of catalytic influences in nature, exhibiting an agency still more subtile and energetic. I refer to contagious and epidemic diseases in animals and plants. An influence goes abroad, and seems to be propagated through the atmosphere, traversing whole continents, and crossing wide oceans, powerful and deadly in its effects, yet inappreciable by the most delicate mechanical or chemical tests. But the phenomena admit of explanation by supposing a movement, either in the particles of the atmosphere, or of the still more subtile and elastic medium that pervades all s.p.a.ce; a movement started at a particular spot, as the cholera in India, and the small-pox or some epidemic from some focus, and communicating an unhealthy movement from atom to atom, till it has encircled the earth and mowed down its hecatombs.

Now, when we look at such facts, who can suppose it improbable that man, who can hardly lift a finger without producing some chemical change, should start some of these movements, that may reach far beyond his imagination? And here, as in the cases that have preceded, we must not estimate the actual change in the const.i.tution of bodies by the apparent; for we know that mult.i.tudes of such changes are pa.s.sing within us and around us, without our cognizance; and yet there may be chemical eyes in the universe quick enough to see them all, and to follow them onward to the final result; for there must be a final resultant of all such forces; nor can we doubt that, some time or other, and to some beings, if not to ourselves, it will be manifest. Here, then, is another mode in which a chemical influence may go forth from us, reaching the utmost limits of matter and of time; nay, perhaps extending into eternity, and revealing our actions to the finer sensibilities of exalted beings.

_I derive my sixth argument in support of the general principle from organic reaction._

Few persons, save the zologist and comparative anatomist, have any idea of the great nicety and delicacy of the relations that exist between all the species of animals and plants, so that what affects one affects all the rest. Perhaps the subject may be ill.u.s.trated by supposing all the species of organic beings to be distributed at different distances through a hollow sphere, while between them all there is a mutual repulsion, and the whole are retained in the form of a sphere by an attracting force directed to the centre. By such an arrangement, if one species be taken out of the sphere, or its repellency become stronger or weaker, the relative position of all the rest would be altered. No matter how many millions of species there are, the movements of one will cause a reaction among all the rest.

Now, this ill.u.s.tration, although an approximation, falls short of representing the actual state of things in nature. It is no exaggeration to say that a relation similar to the supposed one exists throughout the vast dominions of animate beings; so that you cannot obliterate or change one species without affecting all the rest. Often the change is effected so slowly and indirectly that the beings experiencing it are unconscious of it; or they may realize some slight disturbance of the balance in organic nature, and yet be unconscious of the cause. By the ill.u.s.tration above given, when one or more species is removed from the supposed sphere, or its repellent force weakened or strengthened, although an influence will reach all the other species, yet a new equilibrium will soon be established, and no permanently bad effects seem to follow. But not so in nature. There the balance originally fixed between different beings by infinite wisdom is the best possible; and every change, not intended by Providence, must be for the worse. It was intended, for instance, that man should subdue forests and extirpate noxious plants, as well as ferocious and noxious animals; and, therefore, such a change operates to his advantage, but to the injury of the inferior animals. Yet often he pushes this exterminating process so far as to injure himself also. Thus the farmer wages a relentless war against certain birds, because of some slight evils which they occasion. But when they are extirpated, opportunity is given for noxious insects to multiply, and to bring upon the farmer evils much greater than those he thus escapes.

To prevent an excessive multiplication of some species is one of the grand objects of the present balance established among the whole. Such an increase is an inevitable effect of the extinction of a species, and it often occasions great mischief. The carnivorous species, especially, were intended to act as nature's police, to prevent a too great increase of the herbivorous races, which are rendered excessively fruitful to keep the world full. If, then, a carnivorous species become extinct, the species on which it has fed will so multiply as to prove great nuisances, and to produce wide disorder among many species, not only of animals, but of plants. And often has man, in this way, by the extermination of species, in particular districts, unwittingly brought a powerful reaction on himself.

On the Island of New Zealand, within one or two hundred years past, eight or ten species of gigantic birds--the dinornis and palapteryx--have become extinct, probably through the persecution of man. The natives, without doubt, hunted them down for food, until all disappeared: and as no quadruped of much size inhabits the island, we think there is no little plausibility in the suggestion of Professor Owen, that when the birds were all gone, or nearly gone, the natives were tempted to the practice of cannibalism, as the only means of gratifying their pa.s.sion for meat. What a terrible retribution for disturbing the equilibrium of organic nature!

The records of zology and botany afford endless ill.u.s.tration of this subject. But the great truth which they all teach is, that so intimately are we related to other beings, that almost every action of ours reacts upon them for good or evil; for good, upon the whole, when we conform to the laws which G.o.d has established; and for evil, when by their violation we disturb the equilibrium of organized nature, and produce irregular action. In this latter case, we cannot tell where the disturbance, thus introduced, will end; for it is not a periodical oscillation, like the perturbations of the heavenly bodies, nor a mere change of position and intensity by mechanical forces.

But does not this law of mutual influence between organic beings extend to other worlds? Why should it not be transmitted by means of the luminiferous ether to the limits of the universe? Who knows but a blow struck upon a single link of organic beings here may be felt through the whole circle of animate existence in all worlds? That is a narrow view of G.o.d's work, which isolates the organic races on this globe from the rest of the universe. The more philosophical view throws the golden chain of influence around the whole animal creation, whether small or great, near or remote.

Reverting to the reasoning which we employed in tracing out the extent of mechanical reaction, we shall see that organic reaction may extend not only to other worlds, but also into eternity. For if the matter of the universe is to survive the conflagration of the last day, the future economy of life must have some connection with the present, whether this earth or some other part of the universe be the theatre of its development.

I speak here not of moral influences, which we know will pa.s.s over from time into eternity, but of a physical reaction, which may also reach beyond the same gulf. For at least a part of those creatures, who in this world have felt the modifying power of other beings, will survive the world's final catastrophe, and occupy material, though spiritual bodies, whose germ is represented as derived from their bodies on earth. We have reason, then, to suppose some connection and modifying influence between them. And we might show, also, that moral causes, which so affect the physical character here, may exert a like power in eternity. But time will not permit the argument to be followed out.

The conclusion, then, from this argument also, is, that probably every action of ours on earth modifies the condition and destiny of every other created being in this and other worlds through time and eternity. What though human experience, dependent on the bluntness of mortal sensibilities, cannot demonstrate such an influence? Shall the gross perceptions of this disordered world be made the standard of all that exists? Rather let us listen to the suggestions of science, which tell us of the possibility of senses far more acute in other worlds, and in a future state of being--senses that can trace out and feel the vibrations of the delicate web of organic influence that binds together the great and the small, the past, the present, and the future, throughout the universe.

_My seventh argument in support of the general principle depends upon mental reaction._

Mental reaction operates in two ways--indirectly and directly; indirectly through matter, directly by the influence of mind upon mind, without an intervening medium. When describing electric reactions, I have shown how our thoughts and volitions change the electric, chemical, and even mechanical condition of the body, and, through these media, that of all the material universe; and I need not repeat that argument. But to modify the inanimate world through these agencies necessarily affects all other intellects, which are connected with matter; and since man in a future world is to a.s.sume a spiritual body, we may reasonably suppose that all created beings are in some way connected with matter; and, therefore, by means of materialism, through the subtile agencies that have been named, we may be sure that an influence goes out from every thought and volition of ours, and reaches every other intellect in the wide creation. I know not whether, in other worlds, their inhabitants possess sensibilities acute enough to be conscious of this influence; certainly, in this world, it is only to a limited extent that men are conscious of it. Yet we must admit that it exists and acts, or deny the demonstrated verities of science.

But is there not evidence that mind sometimes acts directly upon other minds, without any gross, intervening media? It may, indeed, be doubted whether any created intellect operates, except in connection with some form of matter. Yet there are certain facts in the history of individuals in an abnormal state, which show that one mind acts upon another, independent of the senses, or any other material means or intercommunication discoverable by the senses. Take the details of sleep-waking, or somnambulism; and do not they present us with numerous cases in which impressions are made by one mind upon another, even when separated beyond the sphere of the senses? Take the facts respecting double consciousness, and those where the power was possessed of reading the thoughts, of others, or the facts relating to prevision; and surely they cannot be explained but by the supposition of a direct influence of one mind upon another.
