Passing on toward the point where the process of degradation might begin, which would result in the reduction of this new and divinely constructed animal to a lower form, we have to note, first, that it was made a non-sexual animal, being intended for an angelic type. In the original plan of the gods, it was not contemplated that this primitive type should reproduce itself by any process of generation. According to the original scheme, it would seem that every time a new immortal soul was to be brought down from its peculiar star, the process of constructing for it a mortal body would have to be repeated. Plato, Mr. Grote observes, does indeed tell us that the primitive non-sexual type had the option of maintaining itself. But this must mean that each individual of that type had the option of maintaining itself in its struggle with the debasing influences of appetite and disease. But not one representative of it has held his ground; and as it was foreseen that such an angelic type could not maintain itself, we are to look for a reconstruction of the whole organism. This came about from the degeneracy of the primitive non-sexual animal below the standard of good life which it had the option of continuing. Men whose lives had fallen below this standard became effeminate, cowardly, unjust. In their second birth, their immortal souls had to be translated into a body resembling that to which they had debased the first body into which they were born. The first transition, therefore, was from man into woman. In other words, the gods, seeing that the non-sexual primitive type did not maintain itself at the high point intended for it, reconstructed the whole organism upon the bi-sexual principle, introducing the comparatively lower type of woman. A partial transformation of the male structure makes the female. A suitable adjustment of the male organs, and the implanting of the sexual impulse in both sexes, by the agency of the gods, make provision for generative reproduction, and a species is formed, which takes the place of the primitive non-sexual type which did not reproduce itself in the original scheme. The primitive type disappears, and it disappears by a process of degradation, which it undergoes by reason of its failure to avail itself of the option which it originally had of living a good life that would entitle the immortal soul to return to its peculiar star without further conflict with the debasing tendencies to which it was exposed in the first body that it inhabited.
In this curious theory we see how a process of declension or degradation is induced by what may almost be called a choice, since the primitive human being, by not resisting the debasing tendencies of his lower nature, is made by those tendencies to assume a less divine form than that in which he originally existed. To the primitive man the gods assigned the encephalic or head-soul, which was connected with and suspended from the divine soul of the Kosmos. They assigned it to each man as his presiding genius. If he neglected it, and directed all his development toward the energetic or appetitive mortal soul, he would become debased. He did so. Hence it became necessary for the gods to reconstruct the whole organism, and in this reconstruction the primitive non-sexual type becomes the bi-sexual, and a species is formed.
It is not necessary to enter into the metaphysical argument which relates to the question of responsibility for this change from the original plan. Plato tells us that the gods foresaw it as a necessary consequence of the original scheme; and, moreover, that they foresaw that they must make preparation for the still more degenerate varieties of birds and quadrupeds, into which the corrupt and stupid part of mankind would sink, all of which were according to the great eternal scheme of the four kinds of ideal animals embraced in the idea of the Kosmos itself. But with the moral justice of the whole theory we have no concern here. We are here concerned, first, with the nature of the process by which, in the Platonic theory, the bi-sexual human race became formed out of the primitive non-sexual type; and, next, with the process by which individuals of this race became degraded into the lower animals.[17]
After the process of degradation had begun, after the primitive type had given place to the bi-sexual human race, and a species was thus formed, further degradation would be inevitable under the same causes which produced the first one. The female part of mankind would go on bringing forth new males and new females, and to each one at birth there would come from its peculiar star an immortal soul, for I do not understand that Plato's women were supposed not to be constructed, in this respect, upon the same plan as the men. But each of these newly arrived immortal souls would be placed in a mortal body in contact and conflict with the two mortal souls of appetite, disturbance, and mutiny against the divine laws of reason. Each new human being would then be exposed to further debasement, by which his or her human organs and human form would undergo transformation into a lower type of animal life. Accordingly, we find that Plato, in perfect consistency with his theory, supposes that birds are a degraded birth or formation derived from one peculiar mode of degeneracy in man, hair being transmuted into feathers and wings. If we inquire from what kind of men the birds were formed, and how they came to be assigned to the air, we shall best learn from the words employed by Mr. Grote to express Plato's idea: "Birds were formed from the harmless but light, airy, and superficial men, who, though carrying their minds aloft to the study of cosmical phenomena, studied them by visual observation and not by reason, foolishly imagining that they had discovered the way of reaching truth."[18]
Next to the birds came the land-animals, a more brutal formation. These, to borrow the words of Mr. Grote's analysis, "proceeded from men totally destitute of philosophy, who neither looked up to the heavens nor cared for celestial objects; from men making no use whatever of the rotations of their encephalic soul, but following exclusively the guidance of the lower soul in the trunk. Through such tastes and occupations, both their heads and their anterior limbs became dragged down to the earth by the force of affinity. Moreover, when the rotation of the encephalic soul from want of exercise became slackened and fell into desuetude, the round form of the cranium was lost and became converted into an oblong or some other form. These now degenerated into quadrupeds and multipeds, the gods furnishing a greater number of feet in proportion to the stupidity of each, in order that its approximation to earth might be multiplied. To some of the more stupid, however, the gods gave no feet or limbs at all, constraining them to drag the whole length of their bodies along the ground, and to become reptiles. Out of the most stupid and senseless of mankind, by still greater degeneracy, the gods formed fishes, or aquatic animals—the fourth and lowest genus after men, birds, land-animals. This race of beings, from their extreme want of mind, were not considered worthy to live on earth, or to respire thin and pure air. They were condemned to respire nothing but deep and turbid water, many of them, as oysters and other descriptions of shell-fish, being fixed down at the lowest depth or bottom. It is by such transitions (concludes the Platonic 'Timæus') that the different races of animals passed originally, and still continue to pass, into each other. The interchange is determined by the acquisition or loss of reason or rationality."[19]
Here, then, we have a process of degradation by which the different races of animals were formed, by a kind of selection which, commencing in the human species from the neglect of the encephalic soul to maintain its high duties and aims, goes on in successive debasements which result in the formation of lower and still lower animals until we reach the shell-fish fixed upon the earth at the bottom of the water. The bi-sexual principle of construction having been introduced in the human species, was continued through all the other species formed by the still descending process of deterioration, so that to each successive species there remained the power of reproducing its own type, along with the tendency to evolve a lower type by further loss of reason or rationality. It is not material to the purpose of the parallel, which I am about to draw between the Platonic and the Darwinian system, to consider the precise nature of the Platonic idea of an intelligent power, by which these successive degradations were in one sense purposely ordained. Enough is apparent on the Platonic system to show that, while these degradations were according to an eternal plan, because they resulted from the conflict between reason and unreason, order and disorder, between purity and impurity, yet the different species of animals, after man, were not special creations by an infinite power interfering in each case by a separate exercise of creative will. They were a growth of an inferior organization out of a superior through the inevitable operation of tendencies which changed the forms of the animals. As fast as these tendencies operated—and they were continually operating—the ministers of the Demiurgus, the gods, stood ready to adapt the structure to the new conditions in which the tendencies resulted, so that the new animal might be fitted to and fixed in those conditions. Still, the gods are not represented as making separate creations of new species as an act of their will, without the pre-existing operation in the preceding type of tastes and occupations which modify the structure into one of a more degraded character. It may thus be said with entire truth that the Platonic idea of the origin of the different races of animals presents a parallel to the Darwinian theory, in which it will be found that the one is the reverse of the other, both of them proceeding upon and involving analogous principles of evolution, operating in the one system from below upward, and in the other from a higher point downward. If, in the Platonic system, the idea of an original immortal soul placed in a heavenly abode, but afterward brought down and fixed in a mortal body, is the starting-point—if a conflict of a spiritual and angelic existence with corporeal and earthly tendencies is at first the predominant fact—the parallel between the Platonic process of degradation and the Darwinian process of elevation remains the same; for, in the one system, reason degenerates into instinct, and instinct at last reaches its lowest possible action, or ceases entirely; and, in the other, instinct rises from its lowest action through successive improvements until it becomes mind or intellect: so that somewhere in the two processes there must be a point where they pass each other in opposite directions, the one losing or merging intellect in instinct, the other losing and merging instinct in mind, each of the two processes being a process of development or evolution, but in opposite directions.[20]
It is not easy to ascertain at once what was Mr. Darwin's idea of the mode in which a supreme intelligence has presided over the creation. In his work on "The Descent of Man", he adduces some evidence that man was not "originally endowed with the ennobling belief in the existence of an Omnipotent God," this evidence being that numerous savage races have existed, and still exist, who have had and have no words in their language to express this idea. But this, if true, does not help us to understand what part in Mr. Darwin's theory an Omnipotent God is supposed to play. Scattered through the same work we find references to the hypothesis of such a being, and to the influences which this belief has exerted upon the advance of morality. But I assume that we are to understand that Mr. Darwin adopts as a fact, to be taken into account in judging of his theory of evolution, that there is such a being as an Omnipotent God, having equally the power to make separate creations, or to establish certain laws of matter, and to leave them to operate through secondary causes in the production and extinction of the past and present inhabitants of the world. In his work on the "Origin of Species" he refers to "what we know of the laws impressed upon matter by the Creator."[21] In his "Descent of Man" the following passage occurs toward the close of the work: "He who believes in the advancement of man from some low organized form will naturally ask, How does this bear on the belief in the immortality of the soul? The barbarous races of man, as Sir J. Lubbock has shown, possess no clear belief of this kind; but arguments, derived from the primeval beliefs of savages, are, as we have just seen, of little or no avail. Few persons feel any anxiety from the impossibility of determining at what precise period in the development of the individual, from the first trace of a minute germinal vesicle, man becomes an immortal being; and there is no greater cause for anxiety, because the period can not possibly be determined in the gradually ascending organic scale."
Surely it is a most pertinent inquiry, How does his theory of the advancement of man from some lower organized form bear on the immortality of the soul? and it is no answer to this inquiry to say that upon no hypothesis of man's origin can we determine at what precise period he becomes an immortal being. That the idea of an Omnipotent God, capable of creating a spiritual essence, or an immortal soul, is not denied by Mr. Darwin, is doubtless to be inferred from his strong affirmation that our minds refuse to accept as the result of blind chance the grand sequence of events which the birth both of the species and the individual presents to our view. That variations of structure, the union of pairs in marriage, the dissemination of seeds, and similar events, have all been ordained for some special purpose, is the hypothesis according to which he regards them as events brought about by the laws of natural selection, which laws were ordained by the Creator and left to operate. Now, while this hypothesis excludes, or tends to exclude, the idea of blind chance, it still remains to be considered whether the soul of man, or the essence which we call intellect, is in each case a direct creation of a special character, or whether it is a result from the operation of the laws which have been ordained for the action of organized matter. If it is the former, the soul may survive the destruction of the body. If it is the latter, the soul as well as all the other manifestations or exhibitions which the material body gives forth in its action, may and in all probability must cease with the organs whose action leads us falsely to believe that we are animated by an immortal spirit while we are in the flesh. If it is a necessary result of any theory that what is supposed to be the immortal soul of man is a product of the operation of certain laws imposed upon organized matter, without being a special creation of something distinct from matter, it is immaterial whether the organized form of matter with which the soul is connected, or appears to act for a time, was a special creation, or was an evolution out of some lower form, or came by blind chance. Nor is it material that we can not determine at what precise period in the genesis of the individual, by the ordinary process of reproduction, he becomes an immortal being. The question is, Does he ever become an immortal being, if in body and in mind he is a mere product of organized matter, formed from some lower type through the laws of variation and natural selection, resulting in an animal whose manifestations or exhibitions of what we call intellect or mind are manifestations of the same nature as the instincts of the lower animals, differing only in degree?
That I may not be misunderstood, and especially that I may not be charged with misrepresentation, I will state the case for the Darwinian theory as strongly as I can. The question here is obviously not a question of power. An Omnipotent Creator has just the same capacity to make special creations, by a direct and special exertion of his will, as he has to make one primordial type and place it under fixed laws that will in their operation cause a physical organization to act in such a way as to evolve out of it other and more or less perfect types. In either method of action, he would be the same Omnipotent God, by whose will all things would exist; and I assume that upon this point there is no difference between some of the evolution school and its opponents. But in considering the question of the origin of the human soul, or the intellect of man, we are dealing not with a question of power, but with the probable method in which the conceded Omnipotent capacity has acted. On the one hand, we have the hypothesis that the Eternal and Omnipotent capacity has created a spiritual and immortal being, capable of existing without any union with the body that is formed out of earthly material, but placed for a time in unison with such a body; and that for the effectual purpose of this temporary union this body has been specially constructed, and constructed in two related forms, male and female, so that this created species of animal may perpetuate itself by certain organic laws of reproduction. Now it is obviously immaterial that we can not detect the point of time, or the process, at or by which the union between the spiritual essence and the earthly body takes place in the generation of the individual. It is conceded to be alike impossible to detect the time or mode in which descendants of the lower animals, which had nothing resembling intellect, become endowed with and inhabited by intellect, through the supposed laws of variation and natural selection, operating to produce an animal of a more elaborate organization. The point of divergence between the two hypotheses is precisely this: that the one supposes the mind of man to be a special creation, of a spiritual nature, designed to be immortal, but placed in union with a mortal body for a temporary purpose. The other hypothesis supposes no special creation of either the mind or the body of man, but maintains that the latter is evolved out of some lower animal, and that the former is evolved out of the action of physical organization.[22] Either mode of projecting and executing the creation of both the body and the mind of man is of course competent to an Omnipotent God. The question is, Which mode has the highest amount of probability on which to challenge our belief? If the one, as it is described, leads to the conclusion that the mind can not survive the body, and the other leads to the conclusion that it can, we are left to choose between them: and our choice must be determined by what we can discover of satisfactory proof that the mind of man was destined to become immortal. What, then, is the Darwinian theory of the origin of man as an animal, and to what does it lead respecting the origin and nature of the human soul?
