“That which distinguishes man from the beast,” said Beaumarchais, “is drinking without being thirsty, and making love at all seasons,” and he spoke perhaps truer than he knew, for the fact that man is not bound by seasons and is not in entire subjection to his environment is the cardinal distinction between him and the brutes. This distinction was won through man’s possession of a thinking brain which caused or coincided with an upright carriage whereby his two hands were set free from the lowly service of mere locomotion to make fire and to fashion the tools wherewith he was enabled to control his environment instead of remaining like the animals entirely controlled by it. This wonderful brain also made possible the communication and tradition of his experiences and ideas through articulate speech by which means his successors in each generation were able to keep and develop the slowly spelt lessons of human life.

Are the African Natives as far removed from the beasts as the Europeans, and do they share equally with the Europeans this great human distinction of ability to think?

The belief, at, one time commonly held, that in morphological development and physical appearance the Bantu stand nearer in the scale of evolution to our common ape-like ancestors than do the white people does not seem to be warranted by facts. Careful investigations by trained observers all over the world have shown that the various simian features discernible in the anatomy of modern man are found fairly evenly distributed amongst advanced and backward races.

The so-called prognathism of the Bantu has been cited as a racial mark denoting comparative nearness to the brutes, but when it is noted that anthropologists differ among themselves as to what constitutes this feature, whether it is to be measured from points above or below the nose or both, and when we are informed in some text books that while the negroes are prognathous, bushmen must be classed with Europeans as being the opposite, that is, orthognathous, and when, added to this, we learn from other quarters that white women are, on the average, more prognathous than white men, then the significance of this distinction, which in any case is not regarded as being relative to cranical capacity, is seen to be more apparent than real.

Extreme hairiness of body, on the other hand, which might well be taken as a simian or vestigial character, is seldom met with in the Bantu, but is equally common among Europeans and Australian aboriginals and is found particularly developed in the Ainu of Japan. The texture also of the African’s hair is less like that of the hair of the man-like apes than is the hair of the European. The proportions of the limbs of the Europeans seem, on the average, to be nearer to the supposed prototype of man than those of the Bantu. The specifically human development of the red lips is more pronounced in the African than in the European, and if there is anything in what has been called the “god-like erectness of the human carriage” then it must be admitted that the Bantu women exhibit a straightness of form which may well be envied by the ladies of civilisation.

It is generally accepted that the African Natives have a bodily odour of their own which is sui generis in that it is supposed to be different from that of other human races. Some early travellers have compared it with the smell of the female crocodile, and many people believe it to be a racial characteristic denoting a comparatively humble origin and intended by nature as a signal or warning for the rest of human kind against close physical contact with the African race. A recent student of the Negro question in America gives it as his opinion that this odour is “something which the Negroes will have difficulty in living down." To most Europeans this smell seems to be more or less unpleasant but it must not be forgotten that it does not seem to affect the large numbers of white men of all nationalities who have found and still find pleasure in continued and intimate intercourse with African women. It would seem as if highly “refined” Europeans are nowadays given to exaggerate the sensation produced on their over delicate olfactory nerves by the exhalations caused by perspiration through a healthy and porous skin. In many of the so-called Ladies’ Journals published in England and America advertisements appear regularly vaunting chemical preparations for the disguising of the odour of perspiration which, it is alleged, mars the attractiveness of women. If this is so it would seem that the nostrils of the modern European are rather too easily offended by the natural smell of his kind. However this may be there is no evidence for believing that the African’s bodily smell is more animal-like than that of any other race.

If there is one thing which the white man of South Africa is sure about it is the comparative thickness of the “nigger skull,” but this notion also would appear to be one of the many which have no foundation in fact.

The opinion of medical men, based upon actual observation and measurement, is to the effect that there is no evidence to support the contention that the Native skull is thicker than that of the European. That the thick, woolly hair of the Native may account for his supposed comparative invulnerability to head injuries has not occurred to the layman observer who is more often given to vehement assertion than to careful enquiry.

The supposed arrest of the brain of the Bantu at the age of puberty owing to the closing of the sutures of the skull at an earlier age than happens with Europeans is another popular notion for which a sort of pseudo-scientific authority may be quoted from encyclopaedias and old books of travel. The opinion of modern authorities on this subject is that those who say that the closure of the sutures of the skull determines brain growth would or should also say that the cart pulls the horse, for, if the sutures of the Native skull close at a somewhat earlier date in the average Native than in the average European then it simply means that the Native reaches maturity slightly earlier than the average white man.

The loss of mental alertness which is said by some to be peculiar to the Natives at the time of puberty is very often met with in the European youth or girl at that period of life. Competent observers have of late years come to the conclusion that this supposed falling off in intelligence, in so far as it may differ in degree from what has so often been noticed in European boys and girls at that point of development, is due to psychological and not to physiological causes. It is realised that this lapse in mental power of concentration in European youth in the stage of early adolescence is prevented by the force of example and fear of parental and general reprobation coupled with unbroken school-discipline, all of which factors are as yet seldom present in the surroundings of the average Bantu boy or girl.

The outward ethnic differentiae of the Bantu are admittedly palpable and patent to everyone, but in the opinion of competent observers there is nothing in the anatomy of the black man to make him a lower beast than the man with the white skin. It is now seen that there is no apparent relation between complexion or skull shape and intelligence, but while this is so there appears to be a correlation between the size of the brain and the number of cells and fibres of which it is made up, although this correlation is so weak as to be difficult of demonstration.

The capacity of the normal human cranium varies from 1,000 cubic centimetres to 1,800 cubic centimetres, the mean capacity of female crania being 10 per cent. less than the mean of male crania. On this basis skulls are classified in the text books as being microcephalic when below 1,350 cubic centimetres, such as those of the extinct Tasmanians, Bushmen, Andamanese, Melanesians, Veddahs, and the Hill-men of India; mesocephalic, those from 1,350 to 1,450 cubic centimetres, comprising Negroes, Malays, American Indians, and Polynesians; and megacephalic, above 1,450 cubic centimetres, including Eskimos, Europeans, Mongolians, Burmese and Japanese. The mean capacity among Europeans is fixed at 1,500 cubic centimetres, and the average weight of the brain at 1,300 grams.

These figures show that the skull capacity of the average European is larger than that of the average Negro, and as it seems plausible that the greater the central nervous system, the higher will be the faculty of the race, and the greater its aptitude for mental achievements, the conclusion that the European is superior in this respect seems on the face of it to be well grounded. There are, however, certain relevant facts which qualify this inference, and these must be briefly considered.

The anthropologist Manouvrier measured thirty-five skulls of eminent white men and found them to be of an average capacity of 1,665 cubic centimetres as compared to 1,560 cubic centimetres general average derived from 110 ordinary individuals. On the other hand he found that the cranial capacity of forty-five murderers was 1,580 cubic centimetres, also superior to the general average. Professor Franz Boas, in discussing this experiment, says that most of the brain weights constituting the general series are obtained in anatomical institutes, and the individuals who find their way there are poorly developed on account of malnutrition and of life under unfavourable circumstances, while the eminent men represent a much better nourished class. As poor nourishment reduces the weight and size of the whole body, it will also reduce the size and weight of the brain. Dr. Arthur Keith when dealing with the so-called Piltdown skull in his book “The Antiquity of Man” says to the same effect that the size of brain is a very imperfect index of mental ability in that we know that certain elements enter into the formation of the brain which take no direct part in our mental activity, so that a person who has been blessed with a great robust body and strong, massive limbs requires a greater outfit of mere tracts and nerve cells for the purposes of mere animal administration than the smaller person with trunk and limbs of a moderate size.

It seems fair, therefore, to assume that the brain-weights of big men of the Zulu, the Xosa and the Fingo tribes will be considerably above those of European women, but to conclude from this that the capacity of the big black man is higher than that of the average white woman would hardly be possible to-day. I would say here that I do not accept the suggestion, recently advanced, that the mental faculty of woman is qualitatively different from that of man. I hold that there is no difference of any kind between the intellectual powers of the male and female human being. The comparative lack of mental achievement on the part of women in the past I believe to have been due to a natural, and, as I think, wholesome feminine disinclination to take up intellectual studies and scientific pursuits that until recently have been deemed the prerogative of men, and not to any innate inferiority of the female brain.

According to Professor Sollas, whose high authority cannot be disputed, the size of the brain when looked at broadly seems to be connected with the taxinomic rank of the race, but when we come to details the connection between cranial capacity and mental endowment becomes less obvious. The Eskimo, for instance, who is of short stature, has a cranial capacity of 1,550 cubic centimetres, thus surpassing some of the most civilised peoples of Europe, and yet no one of this race has so far startled the world with any kind of mental achievement. “The result,” says Professor Sollas, “of numerous investigations carried out during the last quarter of a century is to show that, within certain limits, no discoverable relation exists between the magnitude of the brain or even its gross anatomy and intellectual power,” and he illustrates this statement by a list giving the cranial capacities and brain-weights of a number of famous men which shows that though Bismarck had a skull capacity of 1,965 cubic centimetres, Liebniz, who attained to the highest flights of genius, had a cranium measuring only 1,422 cubic centimetres.

Dealing more particularly with the assumed relation between highly specialised mental faculties and the anatomy of the brain, as apart from its mere size, the same author cites the case of Dr. Georg Sauerwein, who was master of forty or fifty languages, and whose brain after his death at the age of 74 in December, 1904, was dissected by Dr. L. Stieda with the idea that, since it is known that the motor centre for speech is situated in what is called Broca’s area, some connection between great linguistic powers and the size or complication of the frontal lobe might be found in this highly specialised brain, but the examination revealed nothing that could be correlated with Sauerwein’s exceptional gift.

Professor R.R. Marett in his handbook on Anthropology says, in discussing the subject of race, “You will see it stated that the size of the brain cavity will serve to mark off one race from another. This is extremely doubtful, to put it mildly. No doubt the average European shows some advantage in this respect as compared, say, with the Bushmen. But then you have to write off so much for their respective types of body, a bigger body going in general with a bigger head, that in the end you find yourself comparing mere abstractions. Again, the European may be the first to cry off on the ground that comparisons are odious; for some specimens of Neanderthal man, in sheer size of brain cavity, are said to give points to any of our modern poets and politicians.... Nor, if the brain itself be examined after death, and the form and number of its convolutions compared, is this criterion of hereditary brain-power any more satisfactory. It might be possible in this way to detect the difference between an idiot and a person of normal intelligence, but not the difference between a fool and a genius."

In his book, “The Human Body,” Dr. Keith, in dealing with racial characters, begs his readers to break away from the common habit of speaking and thinking of various races as high and low. “High and low,” he says, “refers to civilisation; it does not refer to the human body."

The foregoing authoritative opinions serve to show that the Bantu, as compared with other races, labour under no apparent physiological disabilities to hinder them in the process of mental development. Let us now consider in the light of modern psychology upon first-hand and reliable evidence the allegation of mental inferiority that is constantly brought against these people.
