In the crystalline structure, and in the perfect crystals of the older rocks, we learn the laws which predominated at their production. And we find that the same chemical, electrical, and electro-magnetical influences presided over their formation as are now exhibited in the laboratory of the chemist or the laboratory of nature. Now, these crystals conduct us back much farther than the dawn of terrestrial life, though similar ones, and produced by the same laws, are found through the whole series of rocks, from the oldest to the newest. And I might appeal to many other facts in the earth’s history, which demonstrate an identity between the physical laws that have controlled nature’s processes in every period of past time.
We have evidence, also, of the same identity in the laws of life, or organic laws. In the anatomical structure of the earliest animals and plants we find the same general type that pervades the present creation, modified only, as it now is, to meet peculiar circumstances. This is true not only of the osseous, but also of the muscular, circulatory, nervous, lymphatic, and nutritive organs. Hence, as we might expect, we have evidence of the prevalence of the same functional or physiological laws then, as now. Respiration was performed, as it now is, and with the same effects. Vegetable and animal food was then, as now, masticated, digested, and assimilated; and since animals possessed the same senses, we infer that their habits were essentially the same. There is not, indeed, any evidence that ancient animals and plants exhibited any peculiarities of structure or function, save those necessary to adapt them to the circumstances, so unlike the present, in many respects, in which they lived.
We are sure, also, that death has ever reigned over all organic nature. It has always been produced by the same causes, and attended by the same suffering. And its ravages were repaired by the same system of reproduction as now exists. All this we might presume would be the case, upon the discovery of an identity of laws, mechanical, chemical, and organic; but we have direct evidence, also, in the countless remains of animals and plants entombed in the rocks, more than twenty thousand species of which have been disinterred by naturalists and described.
I might multiply facts almost without number to sustain the position, that the same mixed system has ever prevailed upon the globe; for geology is full of the details. But in a subsequent lecture, the subject will be more amply discussed.
Such are the facts respecting the divine benevolence, as they are presented in the volume of nature. Though benevolence decidedly predominates, it is modified by other divine attributes, and ever has been, since organic existence began upon the globe. Let us now, in the fourth place, see what inferences are fairly deducible from the whole subject. For those inferences, if I mistake not, will not only clear away every cloud from the divine benevolence, but throw much light upon man’s condition.
In the first place, the subject shows us that the world is not in a state of retribution.
As a general fact, virtue is to some extent rewarded, and vice to some extent punished. But it is not always so. Indeed, the picture is sometimes reversed apparently; and the good are afflicted because they do good, and the wicked triumph because they do evil. Evil abounds, but it is not so distributed as righteous retribution would award it; neither is good. Since, therefore, God’s justice must be infinitely perfect, there must be some other object for the prevalence of good and evil in the world besides righteous retribution.
Secondly. We learn from the subject that the world is in a fallen condition.
I mean, that man has fallen from holiness and happiness. For the world is evidently not such a world as infinite wisdom and benevolence would prepare for a being perfectly holy and happy. Philosophize as we may, we cannot discover any reason why the abode of such a being should be filled with evils of almost every name—evils which the most consummate prudence and the most elevated virtue cannot wholly avoid—evils which often come upon the good man because he is eminent for holiness. But if man has fallen from original holiness and happiness by transgression, we might expect just such a world to be fitted up for his residence, because evil is indissolubly linked to sin, perhaps in the very nature of things, certainly by divine appointment. We know that it brings a curse upon every thing with which it is connected; and here we see a reason for the blight that has marred some of the fairest features of nature, and introduced pain and suffering into the animal frame, and brought a cloud over man’s noble intellect, and hebetude over his moral powers. Such a fallen condition will explain what no other supposition can, viz., the clouded, fettered, and depressed condition of all organic nature.
Yet, thirdly. We should not infer that man’s condition was hopeless, but rather that mercy might be in store for him.
