Abraham Lincoln actually said...

The world will little note, nor long remember what we say here, but it can never forget what they did here.

It is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced.

The brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add or detract.

You may fool all the people some of the time, and some of the people all the time, but you cannot fool all the people all the time.
