CHAPTER XVI RECAPITULATION; THE RESPECTIVE CHARACTERISTICS OF THE THREE GREAT RACES; THE SUPERIORITY OF THE WHITE TYPE, AND, WITHIN THIS TYPE, OF THE ARYAN FAMILY I have shown the unique place in the organic world occupied by the human species, the profound physical, as well as moral, differences separating it from all other kinds of living creatures. Considering it by itself, I have been able to distinguish, on physiological grounds alone, three great and clearly marked types, the black, the yellow, and the white. However uncertain the aims of physiology may be, however meagre its resources, however defective its methods, it can proceed thus far with absolute certainty. The negroid variety is the lowest, and stands at the foot of the ladder. The animal character, that appears in the shape of the pelvis, is stamped on the negro from birth, and foreshadows his destiny. His intellect will always move within a very narrow circle. He is not however a mere brute, for behind his low receding brow, in the middle of his skull, we can see signs of a powerful energy, however crude its objects. If his mental faculties are dull or even non-existent, he often has an intensity of desire, and so of will, which may be called terrible. Many of his senses, especially taste and smell, are developed to an extent unknown to the other two races.[144] The very strength of his sensations is the most striking proof of his inferiority. All food is good in his eyes, nothing disgusts or repels him. What he desires is to eat, to eat furiously, and to excess; no carrion is too revolting to be swallowed by him. It is the same with odours; his inordinate desires are satisfied with all, however coarse or even horrible. To these qualities may be added an instability and capriciousness of feeling, that cannot be tied down to any single object, and which, so far as he is concerned, do away with all distinctions of good and evil. We might even say that the violence with which he pursues the object that has aroused his senses and inflamed his desires is a guarantee of the desires being soon satisfied and the object forgotten. Finally, he is equally careless of his own life and that of others: he kills willingly, for the sake of killing; and this human machine, in whom it is so easy to arouse emotion, shows, in face of suffering, either a monstrous indifference or a cowardice that seeks a voluntary refuge in death.
