Jefferson's Declaration of Independence is a practical document for the use of practical men. It is not a thesis for philosophers, but a whip for tyrants; it is not a theory of government but a program of action.
There is only one force of history that can break the reign of hatred and resentment and expose the pretensions of tyrants and reward the hopes of the decent and tolerant. And that is the force of human freedom.
Familiarize yourselves with the chains of bondage and you prepare your own limbs to wear them. Accustomed to trample on the rights of others, you have lost the genius of your own independence and become the fit subjects of the first cunning tyrant who rises among you.
The man who is tenacious of purpose in a rightful cause is not shaken from his firm resolve by the frenzy of his fellow citizens clamoring for what is wrong, or by the tyrant's threatening countenance.
