There are several other sciences, whose earlier developments were supposed for a time to be unfavorable to religion; and hence has originated a ground of apprehension respecting science generally. When the Copernican system of astronomy was introduced, it was thought impossible ever to reconcile it to the plain declarations of Scripture; and hence at least one venerable astronomer was obliged to recant that system upon his knees. Similar fears of collision between science and revelation were excited when chemistry announced that the main part of the earth has already been oxidized, and, therefore, could not hereafter be literally burnt. Because some physiologists have been materialists, it has been inferred that physiology was favorable to materialism. But it is now found that they were materialists in spite of physiology, rather than from a correct interpretation of its facts.
Strong apprehensions have also been excited respecting phrenology and mesmerism. And, indeed, in their present aspect, these sciences are probably made to exert a more unfriendly influence upon vital religion than any other. Those who profess to understand and teach them have been, for the most part, decided opponents of special providence and special grace, and many of them materialists. But this is not because there are any special grounds for such opinions in phrenology or mesmerism. The latter branch, indeed, affords such decided proofs of immaterialism, as to have led several able materialists to change their views. Nor does phrenology afford any stronger proof that law governs the natural world, than do the other sciences. But when a man who is sceptical becomes deeply interested in any branch of knowledge, and fancies himself to be an oracle respecting it, he will torture its principles till they are made to give testimony in favor of his previous sceptical views, although, in fact, the tones are as unnatural as those of ventriloquism, and as deceptive. When true philosophy shall at length determine what are the genuine principles of phrenology and mesmerism, we can judge of their bearing upon religion; but the history of other sciences shows us that we need have no fears of any collision, when the whole subject is brought fairly into the daylight.
Upon the whole, every part of science, which has been supposed, by the fears of friends or malice of foes, to conflict with religion, has been found, at length, when fully understood, to be in perfect harmony with its principles, and even to illustrate them. It is high time, therefore, for the friends of religion to cease fearing any injury to the cause of religion from science; and high time, also, for the enemies of religion to cease expecting any such collision.
In conclusion of this argument, we may safely challenge any one to point out a single principle of science which does not in some way illustrate the perfections of the Deity; and if he cannot, scientific truth may be appropriately called religious truth, especially since such illustrations are the highest use to which science can be applied. It is no drawback on the argument because so few make this use of science, nor because some attempt to array science against religion; for this only shows how men may neglect the most important use to which science can be applied, or how they can pervert the richest gifts.
I derive a second argument in support of the general position, that scientific truth is religious truth, from the fact that it will survive the present world, and its examination become a part of the employments and enjoyments of heaven.
The Scriptures are, indeed, sparing in their details of the specific employments of the heavenly world, except so far as worship and praise are concerned. But that worship will undoubtedly be the spontaneous impulse of the heart, (as it is in this world when acceptable,) in view of some manifestations of the divine character. Accordingly, the first sentence of the future song of Moses and the Lamb, as the saints stand with the harps of God upon the sea of glass, is, Great and marvellous are thy works, Lord God Almighty. The works of God, then, will be studied in the future world; and what is that but the study of the sciences? It is, indeed, said by the apostle, that whether there be tongues, they shall cease, [that is, in a future world;] whether there be knowledge, it shall vanish away; and hence it has sometimes been inferred that all the knowledge which we acquire in this world will disappear with this world. But this cannot be the meaning of the passage, for in a variety of places the Bible represents both the righteous and wicked in another world as conscious of what took place on earth; and, unless the nature of the mind be changed at death, it is not possible to conceive that the knowledge we acquire here should be lost. This passage may refer to one of those gifts of inspiration peculiar to apostolic times, called by the sacred writer the word of knowledge. But more probably he meant to teach that, so much brighter and clearer will be the disclosures of another world, that most of our present knowledge will be eclipsed and forgotten. But this does not imply that our future knowledge will be essentially different in nature from that which we acquire on earth. The grand difference is, that now we see through a glass darkly, but then face to face.
We can, also, see why some branches of science cultivated on earth should be very much modified in a future world. There are several, for instance, dependent mainly upon the present organic constitution of nature; and of such branches only the general principles can survive the destruction of the existing framework of animals and plants. Take, for an example, anatomy and physiology. We believe, indeed, that the new earth, wherein dwelleth righteousness, will be material, and that the bodies of men will also be material. But even though these bodies should be organized, we learn from the Scriptures that this organization will be very different from our present bodies. They, says Christ, who shall be accounted worthy to obtain that world, and the resurrection from the dead, neither marry nor are given in marriage, neither can they die any more; for they are equal unto the angels. Paul’s vivid description of the future spiritual body leaves the impression on the mind that it must be very dissimilar to our present bodies. He does not attempt to define the spiritual body, probably because we could not understand the definition, since it would be so unlike any thing on earth. He represents it as incorruptible, powerful, and glorious, entirely in contrast with our present bodies, and declares that it is not flesh and blood, and that it is not organized like our present bodies.
It seems, then, that we have no certain evidence that the future spiritual body will be organized; and in a former lecture we have seen that it is not necessary to suppose it endowed with organs. If not, it is obvious that the sciences of anatomy and physiology can have no existence in a future world, except in the memory. On the other hand, however, there are some things in Paul’s description of the future body that make it quite probable that its organization will be much more exquisite than any thing in existence on earth. He represents it as springing from our present bodies as a germ from a seed; and this would seem to imply organization; though we must not infer too much from a mere rhetorical similitude. But he also represents the spiritual body as far transcending the natural body in glory and in power; and, since the latter is fearfully and wonderfully made, we know of nothing but the most exquisite organization that can give the spiritual body such a superiority over the natural. Admitting that such will be its structure, and, although the nomenclature of anatomy and physiology, which is adapted to flesh and blood, shall pass away and be forgotten, yet analogous sciences shall be substituted, based on facts and principles far more interesting, and developing relations and harmonies far more beautiful. It may be thought, indeed, that, so different will be these sciences from any thing on earth, that there can be no common principles and no link of connection. But the longer a man studies the works of God, the more inclined will he be to regard the universe, material and immaterial, as founded on eternal principles; as, in fact, a transcript of the divine nature; and that all the changes in nature are only new developments of unchanging fundamental laws, not the introduction of new laws. Hence the philosopher would infer that in existing nature we have the prototype of new heavens and a new earth; and although a future condition of things may be as different from the present as the plant is from the seed out of which it springs, still, as the seed contains the embryo of a future plant, so the future world may, as it were, lie coiled up in the present. If in these suggestions there is any truth, there may be a germ in the anatomy and physiology of the present world, which shall survive the destruction of the present economy, and unfold, in far higher beauty and glory, in the more congenial climate of the new heavens and the new earth. If so, the great principles of these sciences which are acquired on earth, and which are so prolific in exhibitions of divine skill, may not prove to be lost knowledge. They shall be recognized as types of those far higher and richer developments of organization which the spiritual body shall exhibit.
It may be still more difficult to show that such a science as botany will have a place in the new earth; simply because we have no certain knowledge of the existence of vegetation there. We can infer nothing on this subject from the figurative representations of the new Jerusalem in Revelation, since the drapery is all derived from this world. But, on the general principle already stated, that the universe constitutes but one vast and harmonious system, and all the economies upon it, past, present, and future, are only different developments of eternal principles, this consideration, I say, should make us hesitate before we infer the annihilation of the vast vegetable kingdom upon the destruction of the present economy of the world. And it does give us an aspect of extreme barrenness and cheerlessness to think of the new earth entirely swept of every thing analogous to the existing foliage, flowers, and fruits. We have attempted to show, however, in another place, that the spiritual body may be of such a nature that it might exist in a temperature so high, or so low, as to prevent the existence of such organic natures as now exist. But how easy for the Deity to create such natures as are adapted to extremes of temperature as wide as we now are acquainted with; and that, too, on the same type as existing nature; so that the new earth, while yet an incandescent, glowing ocean, might teem with animals and plants, organized on the same general principles as those of the present earth! But there is another supposition. I have endeavored to show that change ever has been, and probably ever will be, one of the grand means by which mind is introduced to higher spheres of enjoyment; and even though the new earth at first should be destitute of organic natures, both animal and vegetable, they might be introduced in successive and more perfect economies, as a means of increased happiness, especially to rational natures. These are, indeed, only conjectures; but the balance of probabilities seems to me to incline the mind to the belief that there may be a botany as well as zoölogy in the future world, far transcending their prototypes on earth.
Among the things that we may be certain will pass away with the present world is the mode of communicating our ideas by language. This the apostle expressly declares when he says, Whether there be tongues, [that is, languages,] they shall cease. Now, the acquisition of languages, and the right use of language, or rhetoric and oratory, constitute a large part of what men call learning on earth. And the question is, whether there are any principles on which these branches of knowledge are based that will become the elements of new and higher modes of communicating thought in a future world. These branches are, indeed, rather to be regarded as arts than sciences. Language is the drapery for clothing our thoughts, and, unless we have thoughts to clothe, it becomes useless; and rhetoric and oratory merely show us how to arrange that drapery in the most attractive and impressive style. But there is such a thing as the philosophy of language and the philosophy of rhetoric, whose principles are derived chiefly from moral and intellectual philosophy. And these, we have reason to believe, are eternal. Different as will be the mode of communicating thoughts hereafter from the present, we shall find the same philosophical principles lying at its foundation. Hence we may expect that there will be a celestial language, a celestial rhetoric, and a celestial oratory, in whose beauty and splendor those of earth will be forgotten.
