John Quincy Adams — What has America done for the benefit of mankind?

And now, friends and countrymen, if the wise and learned philosophers of the older world, the first observers of mutation and aberration, the discoverers of maddening ether and invisible planets, the inventors of Congreve rockets and shrapnel shells, should find their hearts disposed to inquire, what has America done for the benefit of mankind? let our answer be this--America, with the same voice which spoke herself into existence as a nation, proclaimed to mankind the inextinguishable rights of human nature, and the only lawful foundations of government. America, in the assembly of nations, since her admission among them, has invariably, though often fruitlessly, held forth to them the hand of honest friendship, of equal freedom, of generous reciprocity. She has uniformly spoken among them, though often to heedless and often to disdainful ears, the language of equal liberty, equal justice, and equal rights. She has, in the lapse of nearly half a century, without a single exception, respected the inde-pendence of other nations, while asserting and maintaining her own. She has abstained from interference in the concerns of others, even when the conflict has been for principles to which she clings, as to the last vital drop that visits the heart. She has seen that probably for centuries to come, all the contests of that Aceldama, the European World, will be contests between inveterate power, and emerging right. Wherever the standard of freedom and independence has been or shall be unfurled, there will her heart, her benedictions and her prayers be. But she goes not abroad in search of monsters to destroy. She is the well-wisher to the freedom and independence of all. She is the champion and vindicator only of her own. She will recommend the general cause, by the countenance of her voice, and the benignant sympathy of her example. She well knows that by once enlisting under other banners than her own, were they even the banners of foreign independence, she would involve herself, beyond the power of extrication, in all the wars of interest and intrigue, of individual avarice, envy, and ambition, which assume the colors and usurp the standard of freedom. The fundamental maxims of her policy would insensibly change from liberty to force. The frontlet upon her brows would no longer beam with the ineffable splendor of freedom and independence; but in its stead would soon be substituted an imperial diadem, flashing in false and tarnished lustre the murky radiance of dominion and power. She might become the dictatress of the world: she would be no longer the ruler of her own spirit.
