“In your hands, my dissatisfied fellow countrymen, and not in mine, is the momentous issue of civil war. The government will not assail you. You can have no conflict without being yourselves the aggressors. You have no oath registered in Heaven to destroy the government, while I shall have the most solemn one to "preserve, protect, and defend it." I am loath to close. We are not enemies, but friends. We must not be enemies. Though passion may have strained, it must not break our bonds of affection. The mystic chords of memory, stretching from every battle-field, and patriot grave, to every living heart and hearth-stone, all over this broad land, will yet swell the chorus of the Union, when again touched, as surely they will be, by the better angels of our nature.”

“...THAT FROM THESE HONORED DEAD WE TAKE INCREASED DEVOTION TO THAT CAUSE FOR WHICH THEY GAVE THE LAST FULL MEASURE OF DEVOTION;...”

“I shall adopt new Muse as fast as they appear to be true Muse.”

“It is not in our forming battlements or bristling seacoasts, or our Army and Navy that makes America great - but rather our reliance in the law of liberty and the religious law God has planted in us.”

“Don't give up. Come on. Just keep on trying. Don't frown. Smile! You can do it. If you just try a little harder. I've got a feeling this whole thing might just work out okay. You'll see. Don't give up. Tomorrow is a brand new day. Now I want to see all of you get up on your feet and look like you're enjoying yourselves. Come on, let's see some of that famous ‘Pennsylvania optimism’ I've heard so much about..." [Excerpted from the recently discovered preamble to Gettysburg Address]”

“Republicans are for both the man and the dollar, but in case of conflict the man before the dollar.”

“Every man is said to have his peculiar ambition. Whether it be true or not, I can say, for one, that I have no other so great as that of being truly esteemed of my fellow-men by rendering myself worthy of their esteem.”

“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 dedicate, we cannot consecrate, we 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 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.” 

“I consider the central idea pervading this struggle is the necessity that is upon us, of proving that popular govenment is not an absurdity. We must settle this question now, whether in a free government the minority have the right to break up the govenment whenever they choose. If we fail it will go far to prove the incapability of the people to govern themselves.”

“I am growing old enough not to care much for the MANNER of doing things.”

“Fellow-citizens, we can not escape history. We of this Congress and this Administration will be remembered in spite of ourselves. No personal significance or insignificance can spare one or another of us. The fiery trial through which we pass will light us down in honor or dishonor to the latest generation.”

“I do the very best I know how—the very best I can; and I mean to keep doing so until the end. If the end brings me out all right, what is said against me won’t amount to anything. If the end brings me out wrong, ten angels swearing I was right would make no difference.”

“A half effort is a wasted effort.”

“Don't believe everything you read on the Internet.”

“The way for a young man to rise is to improve himself every way he can, never suspecting that anybody wishes to hinder him. Allow me to assure you that suspicion and jealousy never did help any man in any situation. There may sometimes be ungenerous attempts to keep a young man down; and they will succeed, too, if he allows his mind to be diverted from its true channel to brood over the attempted injury. Cast about and see if this feeling has not injured every person you have ever known to fall into it.”
