An address delivered to the colored people at Galesburg, Illinois, 1867.
FELLOW-CITIZENS—Slavery has in a thousand forms existed in all ages, and among all people. It is as old as theft and robbery.
Every nation has enslaved its own people, and sold its own flesh and blood. Most of the white race are in slavery to-day. It has often been said that any man who ought to be free, will be. The men who say this should remember that their own ancestors were once cringing, frightened, helpless slaves.
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.
