Some few years ago, when certain ethnographical oligarchs proved to their own satisfaction that the negro was an inferior "type of mankind," they chuckled wonderfully, and avowed, in substance, that it was right for the stronger race to kidnap and enslave the weaker--that because Nature had been pleased to do a trifle more for the Caucasian race than for the African, the former, by virtue of its superiority, was perfectly justifiable in holding the latter in absolute and perpetual bondage! No system of logic could be more antagonistic to the spirit of true democracy. It is probable that the world does not contain two persons who are exactly alike in all respects; yet "_all_ men are endowed by their Creator with certain _inalienable_ rights, among which are life, _liberty_, and the pursuit of happiness." All mankind may or may not be the descendants of Adam and Eve. In our own humble way of thinking, we are frank to confess, we do not believe in the unity of the races. This is a matter, however, which has little or nothing to do with the great question at issue. Aside from any theory concerning the original parentage of the different races of men, facts, material and immaterial, palpable and impalpable--facts of the eyes and facts of the conscience--crowd around us on every hand, heaping proof upon proof, that slavery is a shame, a crime, and a curse--a great moral, social, civil, and political evil--an oppressive burden to the blacks, and an incalculable injury to the whites--a stumbling-block to the nation, an impediment to progress, a damper on all the nobler instincts, principles, aspirations and enterprises of man, and a dire enemy to every true interest. Waiving all other counts, we have, we think, shown to the satisfaction of every impartial reader, that, as elsewhere stated, on the single score of damages to lands, the slaveholders are, at this moment, indebted to us, the non-slaveholding whites, in the enormous sum of nearly seventy-six hundred millions of dollars. What shall be done with this amount? It is just; shall payment be demanded? No; all the slaveholders in the country could not pay it; nor shall we ever ask them for even a moiety of the amount--no, not even for a dime, nor yet for a cent; we are willing to forfeit every farthing for the sake of freedom; for ourselves we ask no indemnification for the past: we only demand justice for the future.
