"While I think as badly of slavery as Horace Greeley did, I am not ashamed that my family were slaveholders. It was our inheritance. Neither am I ashamed that my ancestors were pirates and cattle thieves. People must be judged by the standard of their own age. If it was right to own slaves as property, it was right to fight for it."
January 1, 1970
