Lincoln repeatedly frames the Civil War as a test.
“This is essentially a People’s contest… It is a struggle for maintaining in the world, that form, and substance of government, whose leading object is… to elevate the condition of men.”—First Annual Message to Congress (1861)
“Fellow-citizens, we cannot escape history. We of this Congress and this administration, will be remembered in spite of ourselves… The fiery trial through which we pass, will light us down, in honor or dishonor, to the latest generation.”—Annual Message to Congress (1862)
“Now we are engaged in a great civil war, testing whether that nation, or any nation so conceived and so dedicated, can long endure.”—Gettysburg Address (1863)
Not a tragedy, but a test.
