The intellectual inferiority of the negroes is a common, though most absurd apology, for personal prejudice, and the oppressive inequality of the laws; for this reason, I shall take some pains to prove that the present degraded condition of that unfortunate race is produced by artificial causes, not by the laws of nature. In the first place, naturalists are universally agreed concerning "the identity of the _human_ type;" by which they mean that all living creatures, that can, by any process, be enabled to perceive moral and intellectual truths, are characterized _by similar peculiarities of organization_. They may differ from each other widely, but they still belong to the same class. An eagle and a wren are very unlike each other; but no one would hesitate to pronounce that they were both birds: so it is with the almost endless varieties of the monkey tribe. We all know that beasts, however sagacious, are incapable of abstract thought, or moral perception. The most wonderful elephant in the world could not command an army, or govern a state. An ourang-outang may eat, and drink, and dress, and move like a man; but he could never write an ode, or learn to relinquish his own good for the good of his species. The _human_ conformation, however it may be altered by the operation of physical or moral causes, differs from that of all other beings, and on this ground, the negro's claim to be ranked as a _man_, is universally allowed by the learned. The condition of this people in ancient times is very far from indicating intellectual or moral inferiority. Ethiopia held a conspicuous place among the nations. Her princes were wealthy and powerful, and her people distinguished for integrity and wisdom. Even the proud Grecians evinced respect for Ethiopia, almost amounting to reverence, and derived thence the sublimest portions of their mythology. The popular belief that all the gods made an annual visit to the Ethiopians, shows the high estimation in which they were held; for we are not told that such an honor was bestowed on any other nation. In the first book of the Iliad, Achilles is represented as anxious to appeal at once to the highest authorities; but his mother tells him: "Jupiter set off yesterday, attended by all the gods, on a journey toward the ocean, to feast with the excellent Ethiopians, and is not expected back at Olympus till the twelfth day." In Ethiopia, was likewise placed the table of the Sun, reported to kindle of its own accord, when exposed to the rays of that great luminary. In Africa was the early reign of Saturn, under the appellation of Ouranus, or Heaven; there the impious Titans warred with the sky; there Jupiter was born and nursed; there was the celebrated shrine of Ammon, dedicated to Theban Jove, which the Greeks reverenced more highly than the Delphic Oracle; there was the birth-place and oracle of Minerva; and there, Atlas supported both the heavens and the earth upon his shoulders.
