When they became sufficiently educated to cease enslaving their own people, they then enslaved the first race they could conquer. If they differed in religion, they enslaved them. If they differed in color, that was sufficient. If they differed even in language, it was enough. If they were captured, they then pretended that having spared their lives, they had the right to enslave them. This argument was worthless. If they were captured, then there was no necessity for killing them. If there was no necessity for killing them, then they had no right to kill them. If they had no right to kill them, then they had no right to enslave them under the pretence that they had saved their lives. Every excuse that the ingenuity of avarice could devise was believed to be a complete justification, and the great argument of slaveholders in all countries has been that slavery is a divine institution, and thus stealing human beings has always been fortified with a "Thus saith the Lord." Slavery has been upheld by law and religion in every country. The word Liberty is not in any creed in the world. Slavery is right according to the law of man, shouted the judge. It is right according to the law of God, shouted the priest. Thus sustained by what they were pleased to call the law of God and man, slaveholders never voluntarily freed the slaves, with the exception of the Quakers. The institution has in all ages been clung to with the tenacity of death; clung to until it sapped and destroyed the foundations of society; clung to until all law became violence; clung to until virtue was a thing only of history; clung to until industry folded its arms--until commerce reefed every sail--until the fields were desolate and the cities silent, except where the poor free asked for bread, and the slave for mercy; clung to until the slave forging the sword of civil war from his fetters drenched the land in the master's blood. Civil war has been the great liberator of the world. Slavery has destroyed every nation that has gone down to death. It caused the last vestige of Grecian civilization to disappear forever, and it caused Rome to fall with a crash that shook the world. After the disappearance of slavery in its grossest forms in Europe, Gonzales pointed out to his countrymen, the Portuguese, the immense profits that they could make by stealing Africans, and thus commenced the modern slave-trade--that aggregation of all horror--that infinite of all cruelty, prosecuted only by demons, and defended only by fiends. And yet the slave-trade has been defended and sustained by every civilized nation, and by each and all has been baptized "Legitimate commerce," in the name of the Father, the Son and the Holy Ghost: It was even justified upon the ground that it tended to Christianize the negro. It was of the poor hypocrites who had used this argument that Whittier said, "They bade the slaveship speed from coast to coast, Fanned by the wings of the Holy Ghost."
