Four score and seven years ago our fathers brought forth on 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. We are met on a great battlefield of that war. We have come to 
dedicate a portion of that field, as a final resting place for those who
here gave their lives that that nation might live. It is altogether 
fitting and proper that we should do this.
But, in a larger sense, we can not dedicate, we can not consecrate, 
we can not hallow this ground. The brave men, living and dead, who 
struggled here, have consecrated it, far above our poor power to add or
detract. 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. It is rather for us to be here dedicated 
to the great task remaining before us—that from these honored dead we take 
increased devotion to that cause for which they gave the last full measure 
of devotion—that we here highly resolve that these dead shall not have died 
in vain—that this nation, under God, shall have a new birth of freedom—and 
that government of the people, by the people, for the people, shall not 
perish from the earth.
