This exposition surely carries with it a great deal of naturalness and probability; and if it be true, death to the inferior animals must surely be an indication of great benevolence on the part of the Deity, since it introduces them to a higher state of existence. But if it be rejected, still the general principle is eminently applicable to the case of man.

In the second place, the system of a succession of races of animals on earth, which death alone would render possible, secures a much greater collective amount of happiness than a single race of animals, endowed with earthly immortality. I sustain this position by three arguments. The first is, that young animals enjoy more, in the same period of time, than those more advanced in age. This may result, in part, in the present organization of animals, from the superior health and vigor enjoyed by the young. But it is due, also, in part, and largely, to the novelty of the scenes presented in early life. And so far as it results from the latter cause, it proves that a succession of races would enjoy more than a single race continued indefinitely, because the successive races would always be comparatively young. A single continuous race might, indeed, be supposed always possessed of the unabated vigor and health of youth; but, of necessity, objects must soon lose the charm of novelty, and, therefore, produce less of enjoyment. The second argument is, that a succession of races admits of the contemporaneous existence of a greater number of species than could coexist were none removed by death. If only one undying race occupied the globe, it must subsist exclusively on vegetable food. Whereas much the largest part of the species that now live are carnivorous or omnivorous. All the enjoyment of these flesh-eating animals is, therefore, so much clear gain to the stock of happiness, with the exception of the suffering which death inflicts. Now, but few of the inferior animals perish by disease. Some die by old age, and these suffer almost nothing. But the greater part are suddenly destroyed by the violent assault of the carnivorous races. And as the pangs of death are momentary, and there are no anticipations of its approach, nor sunderings of the ties of affection, nor dread of an hereafter, the suffering endured must be an exceedingly small drawback upon the enjoyment of the whole life. It is far less than it would be, if animals were left to perish by famine, or by slow degrees, from deficient nourishment; so that the existence of the carnivorous races, seeming at first view intended to convert the world into a vast Golgotha, does in fact add greatly to the amount of enjoyment, because it so prodigiously multiplies the number of species of animals, and lessens the sufferings of death. In the third place, death exerts a salutary moral influence upon man, and, as a consequence, swells the amount of his happiness. And although this consideration affects only one species, yet man’s position on the scale of being makes his happiness an object of no small importance.

The final conclusions at which we arrive, then, are, first, that death is a fixed and universal law of nature, essential to the existence of the present system of the world; and secondly, that, like all other laws of nature, it exhibits marks of benevolence, and wise adaptation on the part of the Author of nature. The question will indeed arise in every reflecting mind, why a Being of infinite power and wisdom could not have secured to his creatures the benefits resulting from a system of death, without the attendant suffering. But this question resolves itself into the inquiry, why evil exists at all; and although, in my own view, it exists most probably as a means of greater happiness to the universe, yet on this point the wisest minds have differed and been baffled, and equally perplexing is it to every form of religion. Hence it is no objection to any views we may adopt, that they leave this question where they found it.

The fifth and last step in our investigation of this subject is to show how science, experience, and revelation may be reconciled on the subject of death.

We have seen that geology is not alone in proving death to be a law of nature, essential to the present system of the world, and, indeed, indicative of divine wisdom and benevolence. For anatomy and physiology, as well as experience, teach us the same truths. And natural theology shows that, if death is a law of organic nature, it must have entered into the plan of the universe in the divine mind, and was not the result of any change of organic nature subsequent to the fall of man. Can these views be reconciled with the declarations of Scripture, which certainly represent death among the human family, if not among the lower animals, to be the consequence of sin?

There are three suppositions by which all apparent discrepancy between science and revelation, on this subject, may be removed. I shall present them, with the arguments in their favor, leaving to others to decide which is most reasonable. For they are independent of one another, though not inconsistent; and, therefore, even though different persons should prefer different theories, they need not be regarded as in opposition to one another.

The first theory proceeds on the supposition that death is a universal law of organic nature, from which man was exempted so long as he obeyed the law of God. But I will present it in the language of its distinguished author. “In the state of pristine purity,” says Dr. J. Pye Smith, “the bodily constitution of man was exempted from the law of progress towards dissolution, which belonged to the inferior animals. It must have been maintained in that distinguished peculiarity by means to us unknown; and it would seem probable that, had not man fallen by his transgression, he, and each of his posterity, would, after faithfully sustaining an individual probation, have passed through a change without dying, and have been exalted to a more perfect state of existence.”—Scrip. and Geol. 4th ed. p. 208.

According to this theory of Dr. Smith, man saw all other organic beings around him subject to decay and death, while he, as a special favor, remained unaffected by the general law. The penalty of disobedience was, that he would forfeit this enviable distinction, and be subjected to death more revolting than the brutes. The reward of obedience was a continued immunity from evil, and a final translation, without suffering, to a more exalted condition. And certainly the nature of the case furnishes a strong presumptive argument to show that man did thus stand exempted from the decay and death which reigned all around him. If not, what weight or meaning would there be in the penalty? If he had not seen death in other animals, how could he have any idea of the nature of the threatening? And we may be sure that God never promulgates a penalty without affording his subjects the means of comprehending it.

I have already intimated that I could hardly see why there exists in all organic natures a tendency to decay and death, except in the will of the Creator. May not that tendency result, like the varieties among men, from some slightly modifying cause implanted by the Deity in the nature of the animal or plant? And if so, might not an opposite tendency be imparted to one or more species, so that the decay and death of the one, and the continued existence of the other, might be equally well explained on physiological principles? If this suggestion be admitted, it would not be necessary to resort to any supernatural or miraculous agency to show how sinless man in paradise might have stood unaffected by decay, the common lot of all other races. It must be confessed, however, that it is not as easy to see how, by any natural law, he could have been proof against mechanical violence and chemical agencies; there we must admit miraculous protection, or a self-restoring power more wonderful than that possessed by the polypi.

These views receive strong confirmation from the history of the tree of life, that grew in the garden of Eden. The very name implies that it was intended to give or preserve life. That it had in it a power to preserve life is evident from the sentence pronounced on man. And the Lord God saith, Behold, the man hath become as one of us, to know good and evil; and now, lest he should put forth his hand, and take also of the tree of life, and live forever, therefore the Lord God sent him forth from the garden of Eden. Now, it appears to me to be in perfect harmony with the principles of physiology to suppose that there might be a virtue in the tree of life—either in its fruit or some other part—to arrest that tendency to decay and dissolution which we now find in all animal bodies. It does seem that it would require only some slight modification of the present functions of the human frame to keep the wheels of life in motion indefinitely. When in Eden, man had access to this sure defence against disease. But after he had sinned, he must forfeit this privilege, and, like the plants and inferior animals, submit to the universal law of dissolution. Surely, of all the expositions that have been given of the meaning of this passage, this is the most rational, and it does throw an air of great plausibility over Dr. Smith’s views.
