Buchanan vs. Brownson

Asks Patrick J. Buchanan, "Is America's model of the ideal society -- the more diverse that it is religiously, ethnically, culturally and racially, the better it is -- more than a mildly risky experiment?" — Is Tribalism the Future?

Answered Orestes Augustus Brownson, in The American Republic, in 1865:

There is no civilized nation now existing that developed from a common ancestor this side of Adam, and the most mixed are the most civilized. The nearer a nation approaches to a primitive people of pure unmixed blood, the farther removed it is from civilization. All civilizations are political nations, and are founded in the fact, not on rights antecedent to the fact.
