2. As I have said, the arguments with which we are here concerned refer both to Natural Religion and to Revealed Religion; and there is one of Chalmers' arguments, bearing especially upon the former branch of the subject, which I may begin by noticing. Among the thoughts which, it was stated, might naturally arise in men's minds, when the telescope revealed to them an innumerable multitude of worlds besides the one which we inhabit, was this: that the Governor of the Universe, who has so many worlds under his management, cannot be conceived as bestowing upon this Earth, and its various tribes of inhabitants, that care which, till then, Natural Religion had taught men that he does employ, to secure to man the possession and use of his faculties of mind and body; and to all animals the requisites of animal existence and animal enjoyment. And upon this Chalmers remarks, that just about the time when science gave rise to the suggestion of this difficulty, she also gave occasion to a remarkable reply to it. Just about the same time that the invention of the Telescope showed that there were innumerable worlds, which might have inhabitants requiring the Creator's care as much as the tribes of this earth do,—the invention of the Microscope showed that there were, in this world, innumerable tribes of animals, which had been all along enjoying the benefits of the Creator's care, as much as those kinds with which man had been familiar from the beginning. The telescope suggested that there might be dwellers in Jupiter or in Saturn, of giant size and unknown structure, who must share with us the preserving care of God. The microscope showed that there had been, close to us, inhabiting minute crevices and crannies, peopling the leaves of plants, and the bodies of other animals, animalcules of a minuteness hitherto unguessed, and of a structure hitherto unknown, who had been always sharers with us in God's preserving care. The telescope brought into view worlds as numerous as the drops of water which make up the ocean; the microscope brought into view a world in almost every drop of water. Infinity in one direction was balanced by infinity in the other. The doubts which men might feel as to what God could do, were balanced by certainties which they discovered, as to what he had always been doing. His care and goodness could not be supposed to be exhausted by the hitherto known population of the earth, for it was proved that they had not hitherto been confined to that population. The discovery of new worlds at vast distances from us, was accompanied by the discovery of new worlds close to us, even in the very substances with which we were best acquainted; and was thus rendered ineffective to disturb the belief of those who had regarded the world as having God for its governor.
3. This is a striking reflection, and is put by Chalmers in a very striking manner; and it is well fitted to remove the scruples to which it is especially addressed. If there be any persons to whom the astronomical discoveries which the telescope has brought to light, suggests doubts or difficulties with regard to such truths of Natural Religion as God's care for and government of the inhabitants of the earth, the discoveries of the many various forms of animalcular life which the microscope has brought to light are well fitted to remove such doubts, and to solve such difficulties. We may easily believe that the power of God to sustain and provide for animal life, animal sustenance, animal enjoyment, can suffice for innumerable worlds besides this, without being withdrawn or distracted or wearied in this earth; for we find that it does suffice for innumerable more inhabitants of this earth than we were before aware of. If we had imagined before, that, in conceiving God as able and willing to provide for the life and pleasure of all the sentient beings which we knew to exist upon the earth, we had formed an adequate notion of his power and of his goodness, these microscopical discoveries are well adapted to undeceive us. They show us that all the notions which our knowledge, hitherto, had enabled us to form of the powers and attributes of the Creator and Preserver of all living things, are vastly, are immeasurably below the real truth of the case. They show us that God, as revealed to us in the animal creation, is the Author and Giver of life, of the organization which life implies, of the contrivances by which it is conducted and sustained, of the enjoyment by which it is accompanied,—to an extent infinitely beyond what the unassisted vision of man could have suggested. The facts which are obvious to man, from which religious minds in all ages have drawn their notions and their evidence of the Divine power and goodness, care and wisdom, in providing for its creatures, require, we find, to be indefinitely extended, in virtue of the new tribes of minute creatures, and still new tribes, and still more minute, which we find existing around us. The views of our Natural Theology must be indefinitely extended on one side; and therefore we need not be startled or disturbed at having to extend them indefinitely on the other side;—at having to believe that there are, in other worlds, creatures whom God has created, whom he sustains in life, for whom he provides the pleasures of life, as he does for the long unsuspected creatures of this world.
4. This is, I say, a reflection which might quiet the mind of a person, whom astronomical discoveries had led to doubt of the ordinary doctrines of Natural Religion. But, I think, it may be questioned, whether, to produce such doubts, is a common or probable effect of an acquaintance with astronomical discoveries. Undoubtedly, by such discoveries, a person who believes in God, in his wisdom, power, and goodness, on the evidence of the natural world, is required to extend and exalt his conceptions of those Divine Attributes. He had believed God to be the Author of many forms of life;—he finds him to be the Author of still more forms of life. He had traced many contrivances in the structure of animals, for their sustentation and well-being; his new discoveries disclose to him (for that is undoubtedly among the effects of microscopic researches) still more nice contrivances. He had seen reason to think that all sentient beings have their enjoyments; he finds new fields of enjoyment of the same kind. But in all this, there is little or nothing to disturb the views and convictions of the Natural Theologian. He must, even by the evidence of facts patent to ordinary observation, have been led to believe that the Divine Wisdom and Power are not only great, but great in a degree which we cannot fathom or comprehend;—that they are, to our apprehension, infinite: his new discoveries only confirm the impression of this infinite character of the Divine Attributes. He had before believed the existence of an intelligent and wise Creator, on the evidence of the marks of design and contrivance, which the creation exhibited: of such design and contrivance he discovers new marks, new examples. He had believed that God is good, because he found those contrivances invariably had the good of the creature for their object: he finds, still, that this is the general, the universal scheme of the creation, now when his view of it is extended. He has no difficulty in expanding his religious conceptions, to correspond with his scientific discoveries, so far as the microscope is the instrument of discovery; there is no reason why he should have any more difficulty in doing the same, when the telescope is his informant. It is true, that in this case the information is more imperfect. It does not tell him, even that there are living inhabitants in the regions which
