“But we are not here to applaud manly courage, save as it has been displayed in a noble cause. We must never forget that victory to the rebellion meant death to the republic. We must never forget that the loyal soldiers who rest beneath this sod flung themselves between the nation and the nation's destroyers. If today we have a country not boiling in an agony of blood, like France, if now we have a united country, no longer cursed by the hell-black system of human bondage, if the American name is no longer a by-word and a hissing to a mocking earth, if the star-spangled banner floats only over free American citizens in every quarter of the land, and our country has before it a long and glorious career of justice, liberty, and civilization, we are indebted to the unselfish devotion of the noble army who rest in these honored graves all around us.”

Context: It is a truism, of course, but it is none the less a fact which we must never forget, that this continent and this American community have been blessed with an unparalleled capacity for assimilating peoples of varying races and nations. The continuing migration which in three centuries has established here this nation of more than a hundred million, has been the greatest that history records as taking place in any such brief period. Viewing it historically, we find that the migration to America was little more than a westward projection of the series of great movements of peoples, by which Europe was given its present population. But there is a striking difference between the migrations into Europe, and the later movements of the same racial elements to the New World.

Letter to Sisters at Saint Mary's, 1848.
Context: Let us never forget that if we wish to die like the Saints we must live like them. Let us force ourselves to imitate their virtues, in particular humility and charity.
