Four score and seven years ago our fathers brought forth, upon this continent, a new nation, conceived in liberty, and dedicated to the proposition that all men are created equal. Now we are engaged in a great civil war, testing whether that nation, or any nation, so conceived and so dedicated, can long endure.”

Those are the opening words of Abraham Lincoln’s Gettysburg Address, and they seem eerily prescient today because once again this country finds itself increasingly divided and pondering the future of this great union and the very ideas of liberty and equality for all.
