“Don't interfere with anything in the Constitution. That must be maintained, for it is the only safeguard of our liberties.”

“People who have no vices, have very few virtues.”

“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.” 

“Tact is the ability to describe others as they see themselves.”

“Two principles have stood face-to-face from the beginning of time; and they will ever continue to struggle. The one is the common right of humanity and the other the divine right of kings.”

“If by the mere force of numbers a majority should deprive a minority of any clearly written constitutional right, it might in a moral point of view justify revolution; certainly would if such right were a vital one. But such is not our case.”

“Such will be a great lesson of peace: teaching men that what they cannot take by and election, neither can they take by war; teaching all the folly of being the beginners of a war.”

“I desire so to conduct the affairs of this administration that if at the end, when I come to lay down the reins of power, I have lost every other friend on earth, I shall at least have one friend left, and that friend shall be down inside me.”

“When you reach the end of your rope, tie a knot and hang on.”

“No man who is resolved to make the most of himself can spare time for personal contention.”

“I will not say that we may not sooner or later be compelled to meet force by force; but the time has not yet come, and if we are true to ourselves, may never come. Do not mistake that the ballot is stronger than the bullet. Therefore let the legions of slavery use bullets; but let us wait patiently till November, and fire ballots at them in return; and by that peaceful policy, I believe we shall ultimately win.”

“I know there is a God, and that He hates injustice and slavery. I see the storm coming, and I know that his hand is in it. If He has a place and work for me - and I think He has - I believe I am ready.”

“Never do anything for anyone who can just as well do it themself”

“It's not me who can't keep a secret. It's the people I tell that can't.”

“Passion has helped us; but can do so no more. It will in future be our enemy. Reason, cold, calculating, unimpassioned reason, must furnish all the materials for our future support and defence.”
