America's Founders looked to the lessons of human nature and history to determine how best to structure a government that would promote liberty. They started with the principle of consent of the governed: the only legitimate government is one which the people themselves have authorized. But the Founders also guarded against the tendency of those in power to abuse their authority, and structured a government whose power is limited and divided in complex ways to prevent a concentration of power. They counted on citizens to live out virtues like justice, honesty, respect, humility, and responsibility.

Rights claims have always been central to American political discourse. In the Founders' view, no human being is so decisively superior to other adult human beings that he is entitled to direct their actions without their express consent. By Nature all adult human beings, regardless of their race, sex or class, are free to rule themselves or, what is the same, to exercise the same "inalienable rights," including the right to life, physical liberty, acquire and use property, marry and raise children, communicate one's opinions, and worship God according to the dictates of one's conscience.
