A Review of the Systems of Ethics Founded on the Theory of Evolution

by Cora May Williams

The order in nature cannot be used as the basis of a teleological argument; what we call order of nature is necessity as distinguished from chance. For example, the statement that the life of the earth requires the alternation of day and night means merely that, since day and night alternate upon the earth, only such beings could arise and continue in existence thereon as flourish under this alternation.

The first appearance of protoplasm introduces no strictly new thing, but only a new form of matter with life-motion; and the formation of germs is only a further step of the process. The most important characteristic of all life is sensation. This is the form in which, in all living things, that which in the rest of nature we call reaction, appears. That it is so easy for us to say in the same breath, the animal possesses sensation; and, by this particular excitation we produce in him this particular sensation, has its reason in the fact that the animal is not only capable of sensation, but is, moreover, continually in a state of sensation. By the fact of its continual reaction upon sensation, it keeps itself alive. Hence the two concepts coincide, so to speak; sensation is to life what divisibility is to matter. We express with these words more than a similitude, since all sensation is based upon motion, is, indeed, motion, and every motion may be reduced to a division or differentiation in the broadest sense of the word. All further distinctions, as, for instance, with respect to the mode of sensation (which belongs, without doubt, to plants as well as to animals), we leave unnoticed; all differences in the forms of life are but those of degree, though they may be wide differences of degree; they are to be ascribed to the influence of outer circumstances.

Sensation develops in the direction of least resistance. In the animal world, we have to distinguish between outer and inner factors, with the latter of which a new element seems to be introduced. The difference between the two is not, however, one of essence, since the will, too, is determined by outward circumstance. The inner factors of evolution are comprised in the germ, from which the individual is produced; while the environment constitutes the outer factors. The individual enters the world with a certain reserve quantity of force, which represents his power of resistance to outside forces, and he passes the more rapidly from youth to age the more rapidly this force is consumed. This accumulation of force is, therefore, identical with the impulse to self-preservation, which, as modified by various inner and outer excitations, manifests itself in various forms. But he who, as unimpassioned thinker, desires progress, desires also retrogression; he who desires youth desires age, since the two concepts are correlative and the one includes the other; old age, and finally death, must come to our planet as a whole, as well as to the human individual. The original tendencies of the total character determine, for the most part, the manner in which the individual sustains the struggle for existence; yet the environment is in no less degree active in this determination. Not less important than the manner of reaction is the differing susceptibility to particular kinds of excitation; the character resulting from the mutual action and reaction of individual and world depends upon the manner in which the individual adapts himself to circumstances, ennobles and disciplines himself.

In idealism, as long as it remains within proper bounds, there is certainly truth; he who derides it, derides himself. But realism has also its truth, as long as it does not misjudge the worth of concepts, by which alone we clearly recognize what things are to us, what their relations to us are, and so how we have to deal with them. Concrete concepts inform us as to what is true and what is not true in phenomena. There is no greater mistake than to suppose that what things are in themselves, not what they are for us, is of importance to us; as if we could have an interest in that which things are not for us. The decisive point is the fact that, not things as they appear to us, but their rightly conceived appearance, their appearance as understood by adequate concepts, is the beginning and end of knowledge. Hence the true student of nature can no more do without the concept than the true philosopher can leave material perception out of account. Stiff-necked Materialism is as one-sided as old-time Metaphysics; the one has no meaning for its form, the other no form for its content; the one is a corpse, the other a ghost, and each strives in vain to attain the warmth of life. Natural Science and Philosophy must tread different paths, in so far as division of labor requires them to do so; but they labor at the two sides of one whole. Nature is not a machine, but life in its fullest form, and the task set us is to understand her as she is, not to patch together a nature out of disconnected scraps.

Carneri adopts the definition given by Claude Bernard, to whom life is neither a principle nor a result, but a conflict. To the chemical synthesis, from which protoplasm results, is added, through mechanical integration, morphological synthesis, to whose special form inherited characteristics are related as elements. Through the conflict within living forms, and between these and the rest of the world, motion, attaining to the character of function, appears as continuous consumption. Destruction and renewal are inseparable correlative concepts. This fact is contained in the concept of the conservation of force, work, and motion. We may distinguish between (1) latent life, such as that accumulated in the germ, (2) the merely oscillating plant-life, and (3) free animal life. With this distinction, we place ourselves upon the standpoint of the individual, for whom there is both beginning and end, and to whom renewal is subordinated to destruction; for consumption, death is the characteristic of living in distinction from non-living matter. If, therefore, we regard life as identical with death, we merely assert that we consider death identical with life, and that, in the broader sense of the word, for the universe as a whole, there is no death. That which Claude Bernard designates as Construction is the differentiation and division of labor arising in the process of integration. The cell constitutes the first integration of protoplasm. In it, motion takes place in a particular form, organizes according to this form, causes division and synthesis, and impresses features of character that, by their action and reaction with the environment, either effect their own destruction, or else maintain their existence, propagate themselves, become fixed, and undergo further evolution. In this manner species arise and vary: and the more primitive the form, the more variable it is; the more advanced, the more fixed. Hence the invariable character of the germ-cells. In bone-formation, it is clearly shown that special structure begins very early,—in the cell, namely; but it is preserved only where it is aided by the necessary action and reaction. Autonomic in itself, life submits itself to the general laws of evolution.[67] As the direction of motion is determined for whole groups of cells by the direction of the motion of the protoplasm in the single cells, so organic function is determined by the grouping of the irritable, contractile, sensible cells. From the first origin of life up to its most perfect development, everything is formed at the cost of other forms. If life is, therefore, to be conceived as a conflict, it is a conflict as wide as the universe itself, and we say, with Claude Bernard, that "life may be characterized, but not defined."

Everything that has sensation lives. As life depends upon particular combinations of particular elements, so sensation is the characteristic mark of such combinations, and a higher form of that simple reaction common to nature in general. Reaction has its reason in the motion arising from the endless divisibility of matter, through which the most different combinations and reactions are produced. Since we have before us, in our contemplation of corporeal nature, not abstract matter in general, but some sixty or more special chemical elements, we must, in thinking of atoms, have in mind atoms of these particular elements, and not atoms of abstract matter in general; of such atoms of matter in general, or, if one will, of primordial matter, we can know only that they would in general attract and repel. Only by degrees can a particular reaction of the elements have been developed; and since our known elements have particular different reactions, they must be the product of different combinations. Sensation is due to certain combinations of these elements; when the combinations no longer exist, the atoms of these elements still react according to their characteristic method as atoms of particular elements, but the sensation dependent on their peculiar combinations is destroyed. The atom as such is devoid of sensation, and we may convert our earlier proposition, making it read: Only that which lives is sensible. We know quite well how much of this course of reasoning is of hypothetic nature; but the strictest consistency cannot be denied it. The method which explains life by the assumption of sensible atoms is a much shorter and easier one; but is it not likewise a method of greater risk? And is there no danger that, in rejecting a method by which all changes in phenomena are referred to functions of combinations of elements, we may seek, in matter itself, something that is not matter? The above theory of life, also, takes its departure from the assumption that all was, originally, in the formation of the world, living in the broader sense of the word. But here we are concerned with life in the narrower sense of the word, as distinguished from what we call dead nature.

Soul is, therefore, according to our definition, equivalent to animal life, in contrast to the life of the plant. The significance of the distinction lies in the intermediation of the general organic unity, not in a qualitative division. The elements are the same; only their connection is different, and that which distinguishes the animal is a centralization of the organs. In referring to the possession of soul by the animal, we simply point out the independent manner in which, by reason of sensation, its impulses govern, and develop, through the scale, up to consciousness and will. Of course the gradations are very numerous, inasmuch as the functions of the soul are determined by the development of the organism. The difference between animals whose sensation attains clear consciousness and such as do not attain to more than a mechanical action, does not concern us, as long as we regard the psychical phenomena in their most general form. Every animal possesses soul; we avoid the expression "a soul," as giving the soul the significance of something by itself. In like manner, we do not say that a life, but that life belongs to the animal. The chief condition necessary to soul as to life consists in union to a whole, and soul represents the gradation by which life lifts itself to the plane where it becomes a mirror of the world.

Sensation, as centralized in the brain, becomes perception, the sensation of a part becoming the sensation of the whole, a feeling of the individual. It is perceptions which cause movement. To find a connection between perception as generally understood and the action of the muscle would be as difficult as to show the connection between body and soul in the sense of Spirit. But if we regard perception as feeling, then the awakening of a corresponding impulse, and the transformation of this into will, which finds expression in a corresponding motion, is something so natural that it needs but a glance at the nerve-apparatus in order to comprehend the rapidity of the whole process. With regard to the unconscious character of the greater part of the process, and its corresponding rapidity, we have to consider the gradual nature of the development of the nervous system, the gradual drill of the parts, until the whole process becomes perfect. By feeling is here not meant necessarily feeling as pain or pleasure. This quality of feeling does not necessarily belong to every perception, else thought, as a train of perceptions, would be unbearable; a certain strength of feeling is necessary in order that it may attain the character of pain or pleasure; as we recognize a boundary at which sensation begins, so we recognize one at which feeling begins to attain the character of pleasure and from which, up to a second boundary-line, it continues to appear as pleasure; beyond this line it appears as pain. Moderate feeling is beneficial to the organism, immoderate feeling harmful; hence the appearance of the one as pleasure, and of the other as pain. We say expressly "moderate," not "weak" feeling, because too weak feeling may also, under certain conditions, be painful. Horwicz rightly protests against any attempt to arrange the feelings in an exact scale, since a particular feeling may lead to quite different phenomena of emotion, according to the particular circumstances and the particular development which it undergoes in the organism, and since it is furthermore nothing changeless and distinct, but merely an energy that necessarily leads to activity. Hence it is that the excitation which does not pass the stage of sensation remains localized, but when it attains to the stage of feeling takes possession of the whole individual, and brings the essential tendency of his being[68] to expression.

As Carneri tends to interpret the sensation which he predicates of the lower animals as a mere higher reaction of living matter, and thus wholly mechanical, so he tends to regard the activity of all animals which lack brain (under which he understands especially the nervous developments found in the gray matter which contains Haeckel's "soul-cells") as devoid of pleasure and pain, and due to mere inheritance and force of habit. So the action of the ants is not to be attributed to intelligence, but to mere reaction upon sensation due to inheritance and exercise; and so the movements of a butterfly impaled upon a red-hot needle would be attributable to the hindrance of its flight, not to pain.[69] Thus, with Carneri, the words "sensation," "soul," "perception," and "feeling," lose their ordinary significance; and this fact must be held in mind in the interpretation of his assertions that "all animals have soul," and "all animals have sensation."
