Before a calendar of great Americans can be made out, a valid canon of Americanism must first be established. Not every great man born and bred in America was a great “American.” Some of the notable men born among us were simply great Englishmen; others had in all the habits of their thought and life the strong flavor of a peculiar region, and were great New Englanders or great Southerners; others, masters in the fields of science or of pure thought, showed nothing either distinctively national or characteristically provincial, and were simply great men; while a few displayed odd cross-strains of blood or breeding. The great Englishmen bred in America, like Hamilton and Madison; the great provincials, like John Adams and Calhoun; the authors of such thought as might have been native to any clime, like Asa Gray and Emerson; and the men of mixed breed, like Jefferson and Benton,--must be excluded from our present list. We must pick out men who have created or exemplified a distinctively American standard and type of greatness. To make such a selection is not to create an artificial standard of greatness, or to claim that greatness is in any case hallowed or exalted merely because it is American. It is simply to recognize a peculiar stamp of character, a special make-up of mind and faculties, as the specific product of our national life, not displacing or eclipsing talents of a different kind, but supplementing them, and so adding to the world’s variety. There is an American type of man, and those who have exhibited this type with a certain unmistakable distinction and perfection have been great “Americans.” It has required the utmost variety of character and energy to establish a great nation, with a polity at once free and firm, upon this continent, and no sound type of manliness could have been dispensed with in the effort. We could no more have done without our great Englishmen, to keep the past steadily in mind and make every change conservative of principle, than we could have done without the men whose whole impulse was forward, whose whole genius was for origination, natural masters of the art of subduing a wilderness.
