Brutus, No. 1. The Founders' Constitution. Volumul 1, Capitolul 4, Documentul 14. University of Chicago Press. Accesat 22 ianuarie 2011. "History furnishes no example of a free republic, any thing like the extent of the United States. The Grecian republics were of small extent; so also was that of the Romans. Both of these, it is true, in process of time, extended their conquests over large territories of country; and the consequence was, that their governments were changed from that of free governments to those of the most tyrannical that ever existed in the world".
