“What constitutes an American? Not color nor race nor religion. Not the pedigree of his family nor the place of his birth. Not the coincidence of his citizenship. Not his social status nor his bank account. Not his trade nor his profession. An American is one who loves justice and believes in the dignity of man. An American is one who will fight for his freedom and that of his neighbor. An American is one who will sacrifice… An American is one in whose heart is engraved the immortal second sentence of the Declaration of Independence. Americans have always known how to fight for their rights and their way of life. Americans are not afraid to fight. They fight joyously in a just cause.”

1910s, Address to the Knights of Columbus (1915)
Context: The one absolutely certain way of bringing this nation to ruin, of preventing all possibility of its continuing to be a nation at all, would be to permit it to become a tangle of squabbling nationalities, an intricate knot of German-Americans, Irish-Americans, English-Americans, French-Americans, Scandinavian-Americans or Italian-Americans, each preserving its separate nationality, each at heart feeling more sympathy with Europeans of that nationality, than with the other citizens of the American Republic. The men who do not become Americans and nothing else are hyphenated Americans; and there ought to be no room for them in this country. The man who calls himself an American citizen and who yet shows by his actions that he is primarily the citizen of a foreign land, plays a thoroughly mischievous part in the life of our body politic. He has no place here; and the sooner he returns to the land to which he feels his real heart allegiance, the better it will be for every good American. There is no such thing as a hyphenated American who is a good American. The only man who is a good American is the man who is an American and nothing else.

What is Americanization? (1919)
Context: Every man lives in his neighborhood, and beyond his home and his job. To most men, except in the largest cities, the municipality is interpreted in terms of his neighborhood. Few men get beyond this except through occasional excursions into the larger world. America is a country of parallel neighborhoods; the native American in one section and the immigrant in another. Americanization is the elimination of the parallel line. So long as the American thinks that a house in his street is too good for his immigrant neighbor and tolerates discriminations in sanitation, housing, and enforcement of municipal laws, he can serve on all Americanization Committees that exist and still fail in his efforts. The immigrant neighborhood is often made up of people who have come from one province in the old country. Inevitably the culture of that neighborhood will be that of the old country; its language will persist and its traditions will flourish. It is not that we undervalue these, or desire to discredit them. But separated from the land and surroundings that gave them birth, from the history that cherishes them, they do not remain the strong, beautiful things they were on the other side. These aliens may retain some of the form of culture of the land of their birth long after its spirit has departed or has lost its savor in a new atmosphere. New opportunities, strange conditions, unforeseen adjustments, necessary sacrifices, and forces unseen and not understood affect the immigrant and his life here, and unless this culture is connected and fused with that of the new world, it loses its vitality or becomes corrupt.
