The right of a nation to determine its own form of government does not include the right to establish a slave society (that is, to legalize the enslavement of some men by others).

I like to receive money for my work. But I can pass that up this time. I like to have people know my work is done by me. But I can pass that up. I like to have tenants made happy by my work. But that doesn't matter too much. The only thing that matters, my goal, my reward, my beginning, my end is the work itself. My work done my way. Peter, there's nothing in the world that you can offer me, except this. Offer me this and you can have anything I've got to give. My work done my way. A private, personal, selfish, egotistical motivation. That's the only way I function. That's all I am.
