“Any nation that does not honor its heroes will not long endure.”
Not by Lincoln, this is apparently paraphrased from remarks about honoring him by Hugh Gordon Miller: "I do not believe in forever dragging over or raking up some phases of the past; in some respects the dead past might better be allowed to bury its dead, but the nation which fails to honor its heroes, the memory of its heroes, whether those heroes be living or dead, does not deserve to live, and it will not live, and so it came to pass that in 1909 nearly a hundred millions of people [...] were singing the praises of Abraham Lincoln." — from [http://www.archive.org/details/reportsons00sonsuoft "Lincoln, the Preserver of the Union" (22 February 1911), an address to the Sons of the Revolution in the State of New York.
