The Gettysburg Address
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 cannot dedicatewe cannot consecratewe
cannot 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
usthat from these honored dead we take increased devotion to
that cause for which they
gave the last full measure of devotionthat we here highly
resolve that these dead shall
not have died in vainthat 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.
