Effect of the SciencesThose sciences which exist embodied in the natural world, appear to have been designed to occupy the first place in the development of all minds, or in that which might be called the general development of the mind. These comprise the laws of the animal, vegetable, and mineral kingdoms. The human mind, being as it were planted in nature by its heavenly Father, was designed to enter into matter, and detect knowledge, for its own purposes of growth and nutrition. This gives us a true idea of memory, or rather of what memory should be. We no longer think of a truth as being laid up in a mind for which it has no affinity, and by which it is perhaps never to be used; but the latent affections, as they expand under proper culture, absolutely require the truth to receive them, and its first use is the very nutriment it affords. It is not more difficult for the tree to return to the seed from which it sprung, than for the man who has learned thus, to cease to remember. The natural sciences are the basis of all useful knowledge, alike important to man in whatever time, place, or condition he is found. They are coeval with our race, and must continue so long as the sun, moon, and stars endure. Before there were facts for the pen of history to record, or vices for the arm of law to restrain, or nations for the exhibition of institutions for the government of themselves and intercourse with each other, at the very creation, these were pronounced good in the general benediction; and when history shall have finished her tale of sin and woe, and law shall have punished her millions of offenders, and civil society shall have assumed every possible form, they will remain the same as when presented in living characters to the first parents of the human race. Natural philosophy seems almost essential to an enlightened independence of thought and action. A man may lean upon others, and be so well supported by an equal pressure in all directions, as to be apparently dependent on no one; but his independence is apt to degenerate into obstinacy, or betray itself in weakness, unless his mind is fixed on this unchanging basis. A knowledge of the world may give currency to his sentiments, and plausibility to his manners; but it is more frequently a knowledge of the world that gives light to the path, and stability to the purposes. By the one he may learn what coin is current, by the other what possesses intrinsic value. The natural world was precisely and perfectly adapted to invigorate and strengthen the intellectual and moral man. Its first and highest use was not to support the vegetables which adorn, or the animals which cover, its surface; nor yet to give sustenance to the human body;—it has a, higher and holier object, in the attainment of which these are only means. It was intended to draw forth and mature the latent energies of the soul; to impart to them its own verdure and freshness; to initiate them into its own mysteries; and by its silent and humble 'dependence on its Creator, to leave on them, when it is withdrawn by death, the full impression of his likeness. It was the design of Providence, that the infant mind should possess the germ of every science. If it were not so, they could hardly be learned. The care of God provides for the flower of the field a place wherein it may grow, regale with its fragrance, and delight with its beauty. Is his providence less active over those to whom this flower offers its incense? No. The soil which produces the vine in its most healthy luxuriance is not better adapted to the end, than the world we inhabit to draw forth the latent energies of the soul, and fill them with life and vigor. As well might the eye see without light, or the ear hear without sound, as the human mind be healthy and athletic without descending into the natural world and breathing the mountain air. Is there aught in eloquence, which warms the heart? She draws her fire from natural imagery. Is there aught in poetry, to enliven the imagination? There is the secret of all her power. Is there aught in science to add strength and dignity to the human mind? The natural world is only the body, of which she is the soul. In books, science is presented to the eye of the pupil, as it were in a dried and preserved state; the time may come when the instructor will take him by the hand, and lead him by the running streams, and teach him all the principles of science as she comes from her Maker, as he would smell the fragrance of the rose without gathering it. This love of nature, this adaptation of man to the place assigned him by his heavenly Father, this fulness of the mind as it descends into the works of God, is something which has been felt by every one, though to an imperfect degree; and therefore needs no explanation. It is the part of science, that this be no longer a blind affection; but that the mind be opened to a just perception of what it is which it loves. The affection which the lover first feels for his future wife, may be attended only by a general sense of her external beauty; but his mind gradually opens to a perception of the peculiar features of the soul, of which the external appearance is only an image. So it is with nature. Do we love to gaze on the sun, the moon, the stars, and the planets? This affection contains in its bosom the whole science of astronomy, as the seed contains the future tree. It is the office of the instructor to give it an existence and a name, by making known the laws which govern the motions of the heavenly bodies, the relation of these bodies to each other, and their uses. Have we felt delight in beholding the animal creation, in watching their pastimes and their labors? It is the office of the instructor to give birth to this affection, by teaching the different classes of animals, with their peculiar characteristics, which inhabit the earth, air, and sea. Have we known the inexpressible pleasure of beholding the beauties of the vegetable world? This affection can only expand in the science of botany. Thus it is that the love of nature in the mass, may become the love of all the sciences, and the mind will grow and bring forth fruit from its own inherent power of development. Thus it is that memory refers to the growth and expansion of the mind; and what is thus, as it were, incorporated into its substance, can be forgotten only by a change in the direction of the affections, or the course of conduct of the individual analogous to that in his physical man, by which his very flesh and bones are exchanged for those of a different texture; nor does he then entirely cease to remember, in as much as he preserves a sense of his own identity.
