319 nation, conceived in liberty, and dedicated to the proposition that all men are
320 created equal.
321</p>322<p>323 Now we are engaged in a great civil war, testing whether that nation, or any nation
324 so conceived and so dedicated, can long endure. We are met on a great battlefield
325 of that war. We have come to dedicate a portion of that field as a final resting-place
326 for those who here gave their lives that the nation might live. It is altogether
327 fitting and proper that we should do this. But, in a larger sense, we cannot dedicate,
328 we cannot consecrate, we cannot hallow, this ground.
329</p>330<a href="#" class="more">read more</a>331<p>332 The brave men, living and dead, who struggled here have consecrated it, far above
333 our poor power to add or detract. The world will little note, nor long remember,
334 what we say here, but it can never forget what they did here. It is for us the living,
335 rather, to be dedicated here to the unfinished work which they who fought here have
336 thus far so nobly advanced.
337</p>338<p>339 It is rather for us to be here dedicated to the great task remaining before us—that
340 from these honored dead we take increased devotion to that cause for which they
341 gave the last full measure of devotion—that we here highly resolve that these
342 dead shall not have died in vain—that this nation, under God, shall have a
343 new birth of freedom and that government of the people, by the people, for the people,
344 shall not perish from the earth.
