Excerpt from Letters from an American Farmer, John De Creveoeur(1782):
What then is the American, this new man? He is either an European, or the descendant of an European, hence that strange misture of blood, which you will find in no other country. I could point out to you a family whose grandfather was an Englishman, whose wife was Dutch, whose son married a French woman, and whose present four sons have now four wives of different nations. He is an American.
He is an American, who, leaving behind him all his ancient prejudices and manners, receives new ones from the new mode of life he has embraced, the new government he obeys, and the new rank he holds. He has become an American by being received in the broad lap of our great Alma Mater. Here individuals of all races are melted into a new race of man, whose labors and posterity will one day cause great changes in the world.
