@jgweed,
Thank you for the help. Also if any one would have any more articles on the Declaration and Natural Law, that would help; I am also looking into how the they both can give a meaning to life. I am trying to address this question
What Assumption about ethical Knowledge fits the declaration. Can these assumptions be defended by argument?
I am taking the stance that Jefferson uses Lock's ideas, the stoics, Natural Law. I know that I will have to dispute Relativism, that's fine. Any input thoughts would be good. No extremist view though.
