All the higher animals possess in some degree the powers of memory, judgment, and choice; but in man nature followed the plan of developing enormously the memory, on which depend abstraction, or the power of general ideas, and the reason. In order to secure this result, the brain, or surface for recording experience, was developed out of all proportion with the body. In the average European the brain weighs about 1,360 grams, or 3 per cent. of the body weight, while the average brain weight of some of the great anthropoid apes is only about 360 grams, or, in the orangoutang, one-half of 1 per cent. of the body weight. In point of fact, nature seems to have reached the limit of her materials in creating the human species. The development of hands freed from locomotion and a brain out of proportion to bodily weight are _tours de force_, and, so to speak, an afterthought, which put the heaviest strain possible on the materials employed, and even diverted some organs from their original design. A number of ailments like hernia, appendicitis, and uterine displacement, are due to the fact that the erect posture a.s.sumed when the hands were diverted from locomotion to prehensile uses put a strain not originally contemplated on certain tissues and organs. Similarly, the proportion of idiocy and insanity in the human species shows that nature had reached the limit of elasticity in her materials and began to take great risks. The brain is a delicate and elaborate organ on the structural side, and in these cases it is not put together properly, or it gets hopelessly out of order. This strain on the materials is evident in all races and in both s.e.xes, and indicates that the same general structural ground-pattern has been followed in all members of the species.
Viewed from the standpoint of brain weight, all races are, broadly speaking, in the same cla.s.s. For while the relatively small series of brains from the black race examined by anthropologists shows a slight inferiority in weight--about 45 grams in negroes--when compared with white brains, the yellow race shows more than a corresponding superiority to the white; in the Chinese about 70 grams. There is also apparently no superiority in brain weight in modern over ancient times. The cranial capacity of Europeans between the eleventh and eighteenth centuries, as shown by the cemeteries of Paris, is not appreciably different from that of Frenchmen of today, and the Egyptian mummies show larger cranial capacity than the modern Egyptians. Furthermore, the limits of variation between individuals in the same race are wider than the average difference between races.
In a series of 500 white brains, the lowest and highest brains will differ, in fact, as much as 650 grams in weight.
There is also no ground for the a.s.sumption that the brain of woman is inferior to that of man; for, while the average brain of woman is smaller, the average body weight is also smaller, and it is open to question whether the average brain weight of woman is smaller in proportion to body weight.[257] The importance of brain weight in relation to intelligence, moreover, has usually been much exaggerated by anthropologists; for intelligence depends on the rapidity and range of the acts of a.s.sociative memory, and this in turn on the complexity of the neural processes. Brains are, in fact, like timepieces in this respect, that the small ones work "excellent well" if they are good material and well put together. Although brains occasionally run above 2,000 grams in weight (that of the Russian novelist Turgenieff weighed 2,012), the brains of many eminent men are not distinguished for their great size. That of the French statesman Gambetta weighed only 1,160 grams. It must be borne in mind also that there are many individuals among the lower races and among women having brain weight much in excess of that of that of the average male white.
Of all the possible ways of treating the brain for the purpose of testing its intelligence, that of weighing is the least satisfactory, and has been most indefatigably practiced. A better method, that of counting the nerve cells, has been lately introduced, but to treat a single brain in this way is a work of years, and no series of results exists. In the meantime Miss Thompson, in co-operation with Professor Angell, has completed a study of the mental traits of men and women on what is perhaps the best available principle--that of a series of laboratory tests which eliminate or take into consideration differences due to the characteristic habits of the two s.e.xes. Her findings are probably the most important contribution in this field, and her general conclusion on differences of s.e.x will, I think, hold also for differences of race:
The point to be emphasized as the outcome of this study is that, according to our present light, the psychological differences of s.e.x seem to be largely due, not to difference of average capacity, nor to difference in type of mental activity, but to differences in the social influences brought to bear on the developing individual from early infancy to adult years. The question of the future development of the intellectual life of women is one of social necessities and ideals rather than of the inborn psychological characteristics of s.e.x.[258]
There is certainly great difference in the mental ability of individuals, and there are probably less marked differences in the average ability of different races; but difference in natural ability is, in the main, a characteristic of the individual, not of race or of s.e.x. It is probable that brain efficiency (speaking from the biological standpoint) has been, on the average, approximately the same in all races and in both s.e.xes since nature first made up a good working-model, and that differences in intellectual expression are mainly social rather than biological, dependent on the fact that different stages of culture present different experiences to the mind, and advent.i.tious circ.u.mstances direct the attention to different fields of interest.
II
In approaching the question of the parity or disparity of the mental ability of the white and the lower races, we bring to it a fixed and instinctive prejudice. No race views another race with that generosity with which it views itself. It may even be said that the existence of a social group depends on its taking an exaggerated view of its own importance; and in a state of nature, at least, the same is true of the individual. If self-preservation is the first law of nature, there must be on the mental side an acute consciousness of self, and a habit of regarding the self as of more importance than the world at large.
The value of this standpoint lies in the fact that, while a wholesome fear of the enemy is important, a wholesome contempt is even more so.
Praising one"s self and dispraising an antagonist creates a confidence and a mental superiority in the way of confidence. The vituperative recriminations of modern prize-fighters, the boastings of the Homeric heroes, and the _bogan_ of the old Germans, like the back-talk of the small boy, were calculated to screw the courage up; and the Indians of America usually gave a dance before going on the war-path, in which by pantomime and boasting they magnified themselves and their past, and so stimulated their self-esteem that they felt invincible. In race-prejudice we see the same tendency to exalt the self and the group at the expense of outsiders. The alien group is belittled by attaching contempt to its peculiarities and habits--its color, speech, dress, and all the signs of its personality. This is not a laudable att.i.tude, but it has been valuable to the group, because a bitter and contemptuous feeling is an aid to good fighting.
No race or nation has yet freed itself from this tendency to exalt and idealize itself. It is very difficult for a member of western civilization to understand that the orientals regard us with a contempt in comparison with which our contempt for them is feeble. Our bloodiness, our newness, our lack of reverence, our land-greed, our break-neck speed and lack of appreciation of leisure make Vandals of us. On the other hand, we are very stupid about recognizing the intelligence of orientals. We have been accustomed to think that there is a great gulf between ourselves and other races; and this persists in an undefinable way after scores of j.a.panese have taken high rank in our schools, and after Hindus have repeatedly been among the wranglers in mathematics at Cambridge. It is only when one of the far eastern nations has come bodily to the front that we begin to ask ourselves whether there is not an error in our reckoning.
The instinct to belittle outsiders is perhaps at the bottom of our delusion that the white race has one order of mind and the black and yellow races have another. But, while a prejudice--a matter of instinct and emotion--may well be at the beginning of an error of this kind, it could not sustain itself in the face of our logical habits unless reinforced by an error of the judgment. And this error is found in the fact that in a nave way we a.s.sume that our steps in progress from time to time are due to our mental superiority as a race over other races, and to the mental superiority of one generation of ourselves over the preceding.
In this we are confusing advance in culture with brain improvement. If we should a.s.sume a certain grade of intelligence, fixed and invariable in all individuals, races, and times--an unwarranted a.s.sumption, of course--progress would still be possible, provided we a.s.sumed a characteristically human grade of intelligence to begin with. With a.s.sociative memory, abstraction, and speech men are able to compare the present with the past, to deliberate and discuss, to invent, to abandon old processes for new, to focus attention on special problems, to encourage specialization, and to transmit to the younger generation a more intelligent standpoint and a more advanced starting-point.
Culture is the acc.u.mulation of the results of activity, and culture could go on improving for a certain time even if there were a retrogression in intelligence. If all the chemists in cla.s.s A should stop work tomorrow, the chemists in cla.s.s B would still make discoveries. These would influence manufacture, and progress would result. If a worker in any specialty acquaints himself with the results of his predecessors and contemporaries and _works_, he will add some results to the sum of knowledge in his line. And if a race preserves by record or tradition the memory of what past generations have done, and adds a little, progress is secured whether the brain improves or stands still. In the same way, the fact that one race has advanced farther in culture than another does not necessarily imply a different order of brain, but may be due to the fact that in the one case social arrangements have not taken the shape affording the most favorable conditions for the operation of the mind.
If, then, we make due allowance for our instinctive tendency as a white group to disparage outsiders, and, on the other hand, for our tendency to confuse progress in culture and general intelligence with biological modification of the brain, we shall have to reduce very much our usual estimate of the difference in mental capacity between ourselves and the lower races, if we do not eliminate it altogether; and we shall perhaps have to abandon altogether the view that there has been an increase in the mental capacity of the white race since prehistoric times.
The first question arising in this connection is whether any of the characteristic faculties of the human mind--perception, memory, inhibition, abstraction--are absent or noticeably weak in the lower races. If this is found to be true, we have reason to attribute the superiority of the white race to biological causes; otherwise we shall have to seek an explanation of white superiority in causes lying outside the brain.
In examining this question we need not dwell on the acuteness of the sense-perceptions, because these are not distinctively human. As a matter of fact, they are usually better developed in animals and in the lower races than in the civilized, because the lower mental life is more perceptive than ratiocinative. The memory of the lower races is also apparently quite as good as that of the higher. The memory of the Australian native or the Eskimo is quite as good as that of our "oldest inhabitant;" and probably no one would claim that the modern scientist has a better memory than the bard of the Homeric period.
There is, however, a prevalent view, for the popularization of which Herbert Spencer is largely responsible, that primitive man has feeble powers of inhibition. Like the equally erroneous view that early man is a free and unfettered creature, it arises from our habit of a.s.suming that, because his inhibitions and unfreedom do not correspond with our own restraints, they do not exist. Sir John Lubbock pointed out long ago that the savage is hedged about by conventions so minute and so mandatory that he is actually the least free person in the world. But, in spite of this, Spencer and others have insisted that he is incapable of self-restraint, is carried away like a child by the impulse of the moment, and is incapable of rejecting an immediate gratification for a greater future one. Cases like the one mentioned by Darwin of the Fuegian who struck and killed his little son when the latter dropped a basket of fish into the water are cited without regard to the fact that cases of sudden domestic violence and quick repentance are common in any city today; and the failure of the Australian blacks to throw back the small fry when seining is referred to without pausing to consider that our practice of exterminating game and denuding our forests shows an amazing lack of individual self-restraint.
The truth is that the restraints exercised in a group depend largely on the traditions, views, and teachings of the group, and, if we have this in mind, the savage cannot be called deficient on the side of inhibition. It is doubtful if modern society affords anything more striking in the way of inhibition than is found in connection with taboo, fetish, totemism, and ceremonial among the lower races. In the great majority of the American Indian and Australian tribes a man is strictly forbidden to kill or eat the animals whose name his clan bears as a totem. The central Australian may not, in addition, eat the flesh of any animal killed or even touched by persons standing in certain relations of kinship to him. At certain times also he is forbidden to eat the flesh of a number of animals and at all times he must share all food secured with the tribal elders and some others.
A native of Queensland will put his mark on an unripe zamia fruit, and may be sure that it will be untouched and that when it is ripe he has only to go and get it. The Eskimos, though starving, will not molest the sacred seal basking before their huts. Similarly in social intercourse the inhibitions are numerous. To some of his sisters, blood and tribal, the Australian may not speak at all; to others only at certain distances, according to the degree of kinship. The west African fetish acts as a police, and property protected by it is safer than under civilized laws. Food and palm wine are placed beside the path with a piece of fetish suspended near by, and no one will touch them without leaving the proper payment. The garden of a native may be a mile from the house, unfenced, and sometimes unvisited for weeks by the owner; but it is immune from depredations if protected by fetish.
Our proverb says, "A hungry belly has no ears," and it must be admitted that the inhibition of food impulses implies no small power of restraint.
Altogether too much has been made of inhibition, anyway, as a sign of mentality, for it is not even characteristic of the human species.
The well-trained dog inhibits in the presence of the most enticing stimulations of the kitchen. And it is also true that one race, at least--the American Indian--makes inhibition of the most conspicuous feature in its system of education. From the time the ice is broken to give him a cold plunge and begin the toughening process on the day of his birth, until he dies with out a groan under torture the Indian is schooled in the restraint of his impulses. He does not, indeed, practice our identical restraints, because his traditions and the run of his attention are different; but he has a capacity for controlling impulse equal to our own.
Another serious charge against the intelligence of the lower races is lack of the power of abstraction. They certainly do not deal largely in abstraction, and their languages are poor in abstract terms. But there is a great difference between the habit of thinking in abstract terms and the ability to do so.
The degree to which abstraction is employed in the activities of a group depends on the complexity of the activities and on the complexity of consciousness in the group. When science, philosophy, and logic, and systems of reckoning time, s.p.a.ce, and number are taught in the schools; when the attention is not so much engaged in perceptual as in deliberate acts; and when thought is a profession, then abstract modes of thought are forced on the mind. This does not argue absence of the power of abstraction in the lower races, or even a low grade of ability, but lack of practice. To one skilled in any line an unpracticed person seems very stupid; and this is apparently the reason why travelers report that the black and yellow races have feeble powers of abstraction. It is generally admitted, however, that the use of speech involves the power of abstraction, so that all races have the power in some degree. When we come further to examine the degree in which they possess it, we find that they compare favorably with ourselves in any test which involves a fair comparison.
The proverb is a form of abstraction practiced by all races, and is perhaps the best test of the natural bent of the mind in this direction, because, like ballad poetry, and slang, proverbial sayings do not originate with the educated cla.s.s, but are of popular origin.
At the same time, proverbs compare favorably with the _mots_ of literature, and many proverbs have, in fact, drifted into literature and become connected with the names of great writers. Indeed, the saying that there is nothing new under the sun applies with such force and fidelity to literature that, if we should strip Hesiod and Homer and Chaucer of such phrases as "The half is greater than the whole,"
"It is a wise son that knows his own father" (which Shakespeare quotes the other end about), and "To make a virtue of necessity," and if we should further eliminate from literature the motives and sentiments also in ballad poetry and in popular thought, little would remain but form.
If we a.s.sume, then, that the popular mind--let us say the peasant mind--in the white race is as capable of abstraction as the mind of the higher cla.s.ses, but not so specialized in this direction--and no one can doubt this in view of the academic record of country-bred boys--the following comparison of our proverbs with those of the Africans of the Guinea coast (the latter reported by the late Sir A.B.
