Declaration of Independence, 1776
Please note that the above is not suggesting a "revolutionary" right but rather an intrinsic right of free men!
Why not? Jefferson was certainly talking about revolutionary actions when he wrote the Declaration of Independence since none of the men who signed it were under any illusions that their actions were legal. And there are times when free men must decide that there is no solution within the law and the time has come, as H.L Menken put it, "...to spit on his hands, hoist the black flag, and begin to slit throats." There can be no denying that. All I'm saying is that don't pretend that it's lawful or Constitutional. It is a remedy for when the law and Constitution no longer work. I don't think we're at that point in our history. Obviously others disagree.
The future inhabitants of the Atlantic & Missipi States will be our sons. We leave them in distinct but bordering establishments. We think we see their happiness in their union, & we wish it. Events may prove it otherwise; and if they see their interest in separation, why should we take side with our Atlantic rather than our Missipi descendants? It is the elder and the younger son differing. God bless them both, & keep them in union, if it be for their good, but separate them, if it be better.
