"The better angels of our nature"

These words from the conclusion of Lincoln's First Inaugural Address [March 4, 1861] have relevance to our rather less fraught times:

I am loath to close. We are not enemies, but friends. We must not be enemies. Though passion may have strained it must not break our bonds of affection. The mystic chords of memory, stretching from every battlefield, and patriot grave, to every living heart and hearthstone, all over this broad land, will yet swell the chorus of the Union, when again touched, as surely they will be, by the better angels of our nature.
