The savage tribes of central Africa

The savage tribes of central Africa are evidences of this. Left in their natural condition, they have sunk to the lowest depths and degrees of barbarism, dimly groping in a world of mental and moral obscurity. If we wish to illumine this dark plane of human existence, we must bring man forth from the hopeless captivity of nature, educate him and show him the pathway of light and knowledge, until, uplifted from his condition of ignorance, he becomes wise and knowing; no longer savage and revengeful, he becomes civilized and kind; once evil and sinister, he is endowed with the attributes of heaven. But left in his natural condition without education and training, it is certain that he will become more depraved and vicious than the animal, even to the extreme degree witnessed among African tribes who practice cannibalism. It is evident, therefore, that the world of nature is incomplete, imperfect until awakened and illumined by the light and stimulus of education.
