In addition to this, it may be said that the contrast between the culture represented by the modern white and that of primitive man is far more fundamental than that between the ancients and the people with whom they came in contact. Particularly, the methods of manufacture have developed so enormously, that the industries of the primitive people of our times are exterminated by the cheapness and large quantity of the products imported by the white trader, because primitive man is unable to compete with the power of production of the machines of the whites, while in olden times the superior hand-product rivalled the hand-product of a lower type. When a day’s work suffices for obtaining efficient tools or fabrics from the trader, while the manufacture of the corresponding implement or material by the native himself would have required weeks, it is but natural that the slower and more laborious process should be given up speedily. It must also be considered that in several regions, particularly in America and in parts of Siberia, the primitive tribes are swamped by the numbers of the immigrating race, which is crowding them so rapidly out of their old haunts that no time for gradual assimilation is given. In olden times there was certainly no such immense inequality in numbers as we observe in many regions nowadays.

We conclude, therefore, that the conditions for assimilation in ancient Europe were much more favorable than in those countries where in our times primitive people come into contact with civilization. Therefore we do not need to assume that the ancient Europeans were more gifted than other races which have not become exposed to the influences of civilization until recent times (Gerland, Ratzel).

This conclusion may be corroborated by other facts. In the middle ages the civilization of the Arabs had reached a stage which was undoubtedly superior to that of many European nations of that period. Both civilizations had sprung largely from the same sources, and must be considered branches of one tree. The Arabs who were the carriers of civilization were by no means members of the same race as the Europeans, but nobody will dispute their high merits. It is of interest to see in what manner they influenced the negro races of the Soudan. At an early time, principally between the second half of the eighth century and the eleventh century of our era, the Soudan was invaded by Hamitic tribes, and Mohammedanism was spreading rapidly through the Sahara and the western Soudan. We see that since that time large empires have been formed, and have disappeared again in struggles with neighboring states, and that a relatively high degree of culture has been attained. The invaders intermarried with the natives; and the mixed races, some of which are almost purely negro, have risen high above the level of other African negroes. The history of Bornu is perhaps one of the best examples of this kind. Barth and Nachtigal have made us acquainted with the history of this state, which has played a most important part in the history of North Africa.

Why, then, have the Mohammedans been able to civilize these tribes, and to raise them to nearly the same standard which they had attained, while the whites have not been capable of influencing the negro in Africa to any considerable extent? Evidently on account of the different method of introduction of culture. While the Mohammedans influence the people in the same manner in which the ancients civilized the tribes of Europe, the whites send only the products of their manufactures and a few of their representatives into the negro country. A real amalgamation between the more highly educated whites and the negroes has never taken place. The amalgamation of the negroes by the Mohammedans is facilitated particularly by the institution of polygamy, the conquerors taking native wives, and raising their children as members of their own family.

The spread of the Chinese civilization in eastern Asia may be likened to that of the ancient civilization in Europe. Colonization and amalgamation of kindred tribes, and in some cases extermination of rebellious subjects, with subsequent colonization, have led to a remarkable uniformity of culture over a large area.

When, finally, we consider the inferior position held by the negro race of the United States, although the negro lives in the closest contact with modern civilization, we must not forget that the old race feeling of the inferiority of the colored race is as potent as ever, and is a formidable obstacle to its advance and progress, notwithstanding that schools and universities are open to them. We might rather wonder how much has been accomplished in a short period against heavy odds. It is hardly possible to say what would become of the negro if he were able to live with the whites on absolutely equal terms. Miss Ovington’s discussion of the opportunities of the negro in the United States is a convincing proof of the inequality of the conditions of economic advance of the negro and of the white, even after the abolition of legal inequality.

Our conclusion drawn from the foregoing considerations is the following: Several races have developed a civilization of a type similar to the one from which our own had its origin. A number of favorable conditions facilitated the rapid spread of this civilization in Europe. Among these, common physical appearance, contiguity of habitat, and moderate difference in modes of manufacture, were the most potent. When, later on, civilization began to spread over other continents, the races with which modern civilization came into contact were not equally favorably situated. Striking differences of racial types, the preceding isolation which caused devastating epidemics in the newly discovered countries, and the greater advance in civilization, made assimilation much more difficult. The rapid dissemination of Europeans over the whole world destroyed all promising beginnings which had arisen in various regions. Thus no race except that of eastern Asia was given a chance to develop an independent civilization. The spread of the European race cut short the growth of the existing independent germs without regard to the mental aptitude of the people among whom it was developing. On the other hand, we have seen that no great weight can be attributed to the earlier rise of civilization in the Old World, which is satisfactorily explained as a chance. In short, historical events appear to have been much more potent in leading races to civilization than their faculty, and it follows that achievements of races do not warrant us in assuming that one race is more highly gifted than the other.

After having thus found an answer to our first problem, we turn to the second one: In how far are we justified in considering those anatomical traits in regard to which foreign races differ from the white race as marks of inferiority? In one respect the answer to this question is easier than that to the former. We have recognized that achievement alone does not justify us in assuming greater mental ability for the white race than for others, unless we can sustain our claim by other proofs. It follows from this, that differences between the white race and other races must not be interpreted to mean superiority of the former, inferiority of the latter, unless this relation can be proved by anatomical or physiological considerations.

It may not be amiss to illustrate by an example the logical error which is committed with great ease and great frequency. In a painstaking investigation made a few years ago, Mr. R. B. Bean demonstrated certain characteristic differences between the form of the whole and of the parts of the brain of the Baltimore negro and of the Baltimore white,—differences which consist in the form and relative size of the frontal and occipital lobes and in the size of the corpus callosum. The interpretation of the difference is, that the smaller size of the anterior lobes and of the callosum indicates a lower mental development, a conclusion which has been refuted by Franklin P. Mall. It may suffice here, where we are interested chiefly in the logical fallacy of such conclusions, to call attention to the fact that a comparison of long-headed and short-headed individuals of the same race—or, let us say, of long-headed North French and of short-headed Central French—would result in similar differences, but that in a case of this kind the inference regarding greater or lesser ability would not be made with the same readiness.

There is, of course, no doubt that great differences exist in the physical characteristics of the races of man. The color of the skin, the form of the hair, and the configuration of lips and nose, distinguish the African clearly from the European. The question to decide is, What relations have these features to the mental aptitude of a race? Two points of view may be brought forward in relation to this question. First, we may claim that a race in which peculiarities are found that are characteristic of lower stages in the animal series will be in all respects of an inferior type. Secondly, we may direct our attention primarily to the central nervous system and investigate whether the anatomical structure in one race is superior to that found in another race.
