“As I would not be a slave, so I would not be a master. This expresses my idea of democracy.”

“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.”

“I never tire of reading 

“My great concern is not whether you have failed, but whether you are content with your failure.”

“You cannot have the right to do what is wrong!”

“Believing everyone is dangerous, but believing nobody is more dangerous.”

“I know not how to aid you, save in the assurance of one of mature age, and much severe experience, that you can not fail, if you resolutely determine, that you will not.”

“I remember my mother's prayers and they have always followed me. They have clung to me all my life.”

“How weak and fruitless must be any word of mine.”

“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.”

“in times like the present, men should utter nothing for which they would not willingly be responsible through time and eternity.”

“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 have destroyed my enemies when I make friends with them”

“To sin by silence when they should protest, makes cowards of men.”

“All I have learned, I learned from books.”
