CHAPTER II

General characteristics of the human race – Organic characteristics – Senses and the nervous system – Height – Skeleton – Cranium and face – Colour of the skin – Physiological functions – Intellectual characteristics – Properties of human intelligence – Languages and literature – Different states of society – Primitive industry – The two ages of prehistoric humanity.

Before entering upon a minute description of each of the human races, we shall find it well to lay before the reader a generalization of the characteristics which are common to all.

Since man is an intelligent being, living in an organized frame, our attention has to be directed to the consideration of his organs and intellect, that is, in the first place, we must investigate the physical, in the second, the intellectual and moral elements of his constitution.

The physical characteristics bear but secondary importance among those of the human race. Man is a spirit which shines within the body of an animal, and the only difficulty is to ascertain in what manner the organism of the mammalia is modified in order to become that of man; to compare the harmony of this organism with the object in view, namely the exercise of human intellect and thought. We shall see that the organs of the mammalia are greatly modified in the human subject, becoming, either on account of their individual excellence or the harmony of their combination, greatly superior to the associations of the same organs among animals.

Let us first consider the brain and organs of sense. When we examine the form and relative size of the brain in ascending the series of mammiferous animals, we find that this organ increases in volume, and progresses, so to say, toward the superior characteristics which it is to display in the human species. Disregarding certain exceptions, for the existence of which we cannot account, but which in no way alter the general rule, the brain increases in importance from the zoophyte to the ape. But, in comparing the brain of the ape with that of man, an important difference becomes at once apparent. The brain of the gorilla, orang-outang, or chimpanzee, which are the apes that bear the greatest resemblance to man, and which for that reason are designated anthropomorphous apes, is very much smaller than that of man. The cerebral lobes in man are much longer than in the anthropomorphous apes, and their vertical measure is out of all proportion with the height of the cerebral lobes in apes; this is what produces the noble frontal curve, one of the characteristic features of the human physiognomy. The cerebral lobes are connected behind with a third nervous mass called the cerebellum. The large volume of these three lobes, the depth and number of convolutions of the encephalic mass, and other anatomical details of the brain, upon which we are unable here to treat at greater length, place the brain of man very far above that of the animal nearest to him in the zoological scale. These differences bear witness in favour of man to an unparalleled intellectual development, and we should be better able to measure these differences, were we able to show in what the cerebral action consists, but this we are utterly unable to do.

The senses, taken individually, are not more developed in man than they are in certain animals; but in man they are characterised by their harmony, their perfect equilibrium, and their admirable appropriation to a common end. Man, it will at once be admitted, is not so keen of sight as the eagle, nor so subtle of hearing as the hare, nor does he possess the wonderful scent of the dog. His skin is far from being as fine and impressionable as that which covers the wing of a bat. But, while among animals, one sense always predominates to the disadvantage of the rest, and the individual is thus forced to adopt a mode of existence which works hand in hand with the development of this sense, with man, all the senses possess almost equal delicacy, and the harmony of their association makes up for what may be wanting in individual power. Again, the senses of animals are employed only in satisfying material necessities, while in man, they assist in the exercise of eminent faculties whose development they further.

Let us consider shortly in detail our senses.

Man is certainly better off, as regards the sense of sight, than a large majority of animals. Instead of being placed upon different sides of his head, looking in opposite directions, and receiving two images which cannot possibly be alike, his eyes are directed forwards, and regard similar objects, by which means the impression is doubled. The sense of sight thus brings to his conceptions a complete image and solid idea of what surrounds him; it is his most useful sense, the more so when it is guided in its application by a clear intellect.

The sense of touch in man reaches a degree of perfection which it does not attain in animals. How marvellous is the sense of touch when exercised by applying the extremities of the fingers, the part of the body the best suited to this function, and how much more wonderful is the organ called the hand, which applies itself in so admirable a manner to the most different surfaces whose extent, form, or qualities, we wish to ascertain!

A modern philosopher has attributed to the hand alone our intellectual superiority. This was going too far. We find enthusiasm allied with justice in the views expressed in the excellent pages which Galen has consecrated to a description of the hand, in his immortal work De usu partium.

“Man alone,” says Galen, “is furnished with hands, as he alone is a participator in wisdom. The hand is a most marvellous instrument, and one most admirably adapted to his nature. Remove his hand, and man can no longer exist. By its means he is prepared for defence or attack, for peace or war. What need has he of horns or talons? With his hand, he grasps the sword and lance, he fashions iron and steel. Whilst with horns, teeth and talons, animals can only attack or defend at close quarters, man is able to project from afar the instruments with which he is armed. Shot from his hand, the feathered arrow reaches at a great distance the heart of an enemy, or stops the flight of a passing bird. Although man is less agile than the horse and the deer, yet he mounts the horse, guides him, and thus successfully hunts the deer. He is naked and feeble, yet his hand procures him a covering of iron and steel. His body is unprotected against the inclemencies of climate, yet his hand finds him a convenient abode, and furnishes him with clothing. By the use of his hand, he gains dominion and mastery over all that lives upon the earth, in the air, or in the depths of the sea. From the flute and lyre with which he amuses his leisure, to the terrible instruments by means of which he deals death around him, and to the vessel which bears him, a daring seaman, upon the bosom of the deep – all is the work of his hand.

“Would man without hands have been able to write out the laws which govern him, or raise to the gods statues and altars? Without hands could he bequeath to posterity the fruit of his labours, and the memory of his deeds? Could he (had man been created handless) converse with Socrates, Plato, Aristotle, and the different great men, children of bygone ages? The hand is then the physical characteristic of man, in like manner as intelligence is his moral characteristic.”

Galen, having shown in this chapter the general formation of the hand and the special disposition of the organs which compose it; having described the articulations and bones, the muscles and tendons of the fingers; and having analyzed the mechanism of the different movements of the hand, cries, full of admiration for this marvellous structure:

“In presence of the hand, this marvellous instrument, cannot we well treat with contempt the opinion of those philosophers who saw in the human body merely the result of a fortuitous concourse of atoms! Does not everything in our organization most clearly give the lie to this false doctrine? Who will dare to invoke chance in explanation of this admirable disposition? No, it is no blind power that has given birth to all these marvels. Do you know among men a genius capable of conceiving and executing so perfect a work? There exists not such a workman. This sublime organization is the creation of a superior intelligence, of which the intellect of man is but a poor terrestrial reflection. Let others offer to the Deity reeking hecatombs, let them sing hymns in honour of the gods; my hymn of praise shall be the study and the exposition of the marvels of the human frame!”

The sense of hearing, without attaining in man the perfection which it reaches in certain animals, is nevertheless of great delicacy, and becomes an infinite resource of instruction and pure enjoyment. Not only are differences of intonation, intensity, and timbre, recognised by our ear, but the most delicate shades of rhythm and tone, the relations of simultaneous and successive sounds which give the sentiment of melody and harmony, are appreciated, and furnish us with the first and most natural of the arts – music. Thus the perfection and delicacy of our senses, which permit of our grasping faint and slightly varying impressions, the harmony of these senses themselves, their perfect equilibrium, their capability of improvement by exercise, place us at a considerable distance above the animal.

Let us now pass to the bony portion of the human body, and consider first of all the head. The head is shared by two regions, the cranium and the face. The predominance of either of these regions over the other, depends upon the development of the organs which belong to each.

The cranium contains the cerebral mass, that is, the seat of the intellect; the face is occupied by the organs appertaining to the principal senses. In animals, the face greatly exceeds the cranium in extent; the reverse is, however, the case with man. It is but rarely that with him the face assumes importance at the expense of the cranium – in other words, that the jaws become elongated, and give to the human face the aspect of a brute.

We find in works upon anthropology some expressions which call for an explanation here; they are frequently employed, since they enable us to express by a single term the relation which exists between the dimensions of any particular skull. The term dolichocephalous (from the Greek δολιχος, long, κεφαλη, head,) is applied to a cranium which is elongated from front to rear, or, to express the idea numerically, the cranium whose longitudinal diameter bears to its vertical diameter the proportion of 100 to 68. A short cranium is styled brachycephalous (from βραχυς, short, κεφαλη, head,) which term is applied when the relation between the longitudinal and vertical diameters is 100 to 80.

The attribute of length or shortness of the cranium is of less importance than is generally believed. All Negroes, it is true, are dolichocephalous; but it must not be supposed from this that the production backwards of the cranium is an indication of inferiority; since in the white race, heads are sometimes very long and sometimes very short. The North Germans are dolichocephalous; those inhabiting Central Germany being brachycephalous. This characteristic cannot therefore be regarded as a criterion of intellectual excellence.

There is in the human face an anatomical characteristic of greater importance than any taken from the elongation of the cranium; that is, the projection forwards, or the uprightness of the jaws. The term prognathism (from προ, forward, and γναθος, jaw,) is applied to this jutting forward of the teeth and jaws, and orthognathism (from ορθος, straight, γναθος, jaw,) to the latter arrangement.

It was long admitted that prognathism, or projection of the jaws, was peculiar to the Negro race. But this opinion has been forced to yield to the discovery, that projecting jaws exist among people in no way connected with the Negro. In the midst of white populations this characteristic is frequently met with; it is occasionally found among the English, and is by no means rare at Paris, especially among women. Prognathism would appear to be characteristic of a small European race dwelling to the south of the Baltic Sea, the Esthonians, and which itself is but the residue of the primitive Mongolian race to which we have alluded in our work, “Primitive Man,” as being the first race which, according to M. Pruner-Bey, peopled the globe. It is probably the mixture of Esthonian blood with that of the inhabitants of Central Europe, which causes the appearance in our large cities of individuals whose faces are prognathous.

We cannot close our remarks upon the face without speaking of a curious relation between it and the cranium, which has been much abused; we allude to the facial angle. By facial angle is meant the angle which results from the union of two lines, one of which touches the forehead, the other of which, drawn from the orifice of the ear, meets the former line at the extremity of the front teeth.

The Dutch anatomist Camper, after having compared Greek and Roman statues, or medals of either nationality, assumed that the cause of the intellectual superiority which distinguished Greek from Roman physiognomies was to be found in the fact, that, with the Greeks, the facial angle is larger than in Roman heads. Starting with this observation, Camper pursued his enquiries until it occurred to him to advance the theory that the increase of the facial angle may be taken in the human race as a sign of superior intelligence.
