their own destruction, and sooner or later fall a conquest to ruder and simpler societies, the intellectual superiority of the white man always enables him to conquer inferior races, whatever may be the disparity of numbers, and Clive with three thousand Europeans, attacking the Hindoo horde of one hundred thousand, or Cortez invading Mexico with five hundred followers, amply illustrates the natural supremacy of the Caucasian race. But, on the contrary, if the Aztecs had had the intellectual capacity of the Caucasian superadded to their own specific qualities—the strength and acuteness of the senses—common to the native race, not alone would Cortez have failed to conquer them, but it may be doubted if all Europe, combined together for that purpose, could have accomplished it. There are no examples for testing the capabilities of negroes in these respects, for there is no instance in history where they have contested the supremacy of the white man, the insurrection in Hayti having been the work of the “colored people” and mulattoes, and the negroes only forced into it by their fears after the outbreak was complete. But we have the actual physical facts as well as our every-day experience of the negro qualities, and therefore can arrive at positive truth when comparing him with the superior race. The large distribution of nervous matter to the organs of sense and consequent dominating sensualism (not mere animalism), is the direct cause of that extreme sloth and indolence universal with the race. The small brain and limited reasoning power of the negro render him incapable of comprehending the wants of the future, while the sloth dependent on the dominating sensualism, together with strong animal appetites impelling him always to gross self-indulgence, render a master guide or protector essential to his own welfare. Indeed it may be matter of doubt which is the paramount cause of the negro’s inability to provide for future necessities—his limited reasoning power or his indolence—his small brain or his dominating sensualism. It is a statistical _fact_ that “free” negroes do not produce sufficient for their support, and consequently that they tend perpetually to extinction, and when it is remembered that the small brain and feeble intellectual power render them incapable of reasoning on the future rewards of self-denial, and that the large distribution of nervous matter in the organs of sense, and the consequent sensualism impels them to gross indulgence of the present, and moreover that they are in juxtaposition, and must contend with white people, then it is plain enough to see that it could not be otherwise, and that the total extinction of these unfortunate beings is necessarily a question of time alone.
