“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.” 

“Everything I ever learned, I learned from books.”

“Allow the President to invade a neighboring nation, whenever he shall deem it necessary to repel an invasion and you allow him to do so whenever he may choose to say he deems it necessary for such purpose -- and you allow him to make war at pleasure. . . . If, today, he should choose to say he thinks it necessary to invade Canada to prevent the British from invading us, how could you stop him? You may say to him, 'I see no probability of the British invading us'; but he will say to you, 'Be silent; I see it, if you don't.”

“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 this government of the people, by the people, for the people, shall not perish from the earth.”

“Be not deceived. Revolutions do not go backward.”

“Хората са толкова щастливи, колкото съзнанието им позволява.”

“These [the armed forces] are not our reliance against a resumption of tyranny in our fair land. All of them may be turned against our liberties, without making us stronger or weaker for the struggle. Our reliance is in the love of liberty which God has planted in our bosoms. Our defense is in the preservation of the spirit which prizes liberty as the heritage of all men, in all lands, every where.... Familiarize yourselves with the chains of bondage, and you are preparing your own limbs to wear them. Accustomed to trample on the rights of those around you, you have lost the genius of your own independence, and become the fit subjects of the first cunning tyrant who rises.”

“Better to remain silent and be thought a fool than to speak out and remove all doubt.”

“Take all that you can of this book upon reason, and the balance on faith, and you will live and die a happier man. (When a skeptic expressed surprise to see him reading a Bible)”

“Force is all conquering, but it's victories are short lived.”

“And this, too, shall pass away.' How much it expresses! How chastening in the hour  of pride! How consoling in the depths of affliction!”

“If there is anything that links the human to the divine, it is the courage to stand by a principle when everybody else rejects it.”

“Education does not mean teaching people what they do not know. It means teaching them to behave as they do not behave.”
