Letters From An American Farmer by J. Hector St. John De Crevecoeur
What then is the American, this new man?...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. Americans are the western pilgrims. (from "Letter III," 1782)
