“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.”

“A friend is one who has the same enemies as you have.”

“I am naturally anti-slavery. If slavery is not wrong, nothing is wrong.”

“Do I not destroy my enemies when I make them my friends?”

“RESPONSE TO POLITICAL SMEAR TO ROBERT ALLEN New Salem, June 21, 1836 DEAR COLONEL:—I am told that during my absence last week you passed through this place, and stated publicly that you were in possession of a fact or facts which, if known to the public, would entirely destroy the prospects of N. W. Edwards and myself at the ensuing election; but that, through favor to us, you should forbear to divulge them. No one has needed favors more than I, and, generally, few have been less unwilling to accept them; but in this case favor to me would be injustice to the public, and therefore I must beg your pardon for declining it. That I once had the confidence of the people of Sangamon, is sufficiently evident; and if I have since done anything, either by design or misadventure, which if known would subject me to a forfeiture of that confidence, he that knows of that thing, and conceals it, is a traitor to his country’s interest. I find myself wholly unable to form any conjecture of what fact or facts, real or supposed, you spoke; but my opinion of your veracity will not permit me for a moment to doubt that you at least believed what you said. I am flattered with the personal regard you manifested for me; but I do hope that, on more mature reflection, you will view the public interest as a paramount consideration, and therefore determine to let the worst come. I here assure you that the candid statement of facts on your part, however low it may sink me, shall never break the tie of personal friendship between us. I wish an answer to this, and you are at liberty to publish both, if you choose. Very respectfully, A. LINCOLN.”

“If friendship is your weakest point, then you are the strongest person in the world.”

“In giving freedom to the slave, we assure freedom to the free -- honorable alike in what we give, and what we preserve. We shall nobly save, or meanly lose, the last best hope of earth”

“If you would win a man to your cause, first convince him that you are his sincere friend.”

“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.” 

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

“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.”

“Teach the children so it won't be necessary to teach the adults.”

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