“Important principles may and must be inflexible.”

“That some achieve great success, is proof to all that others can achieve it as well.”

“I know of nothing so pleasant to the mind, as the discovery of anything which is at once new and valuable--nothing which so lightens and sweetens toil, as the hopeful pursuit of such discovery.”

“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.”

“Women are the only people I am afraid of who I never thought would hurt me”

“Upon the subject of education ... I can only say that I view it as the most important subject which we as a people may be engaged in.”

“If Abraham Lincoln were alive now, he'd roll over in his grave.”

“They [the signers of the Declaration of Independence] did not mean to assert the obvious untruth that all were then actually enjoying that equality, nor yet that they were about to confer it immediately upon them. In fact, they had no power to confer such a boon. They meant simply to declare the right; so that the enforcement of it might follow as fast as circumstances should permit.”

“Be with a leader when he is right, stay with him when he is still right, but, leave him when he is wrong.”

“Honor to the soldier and sailor everywhere, who bravely bears his country's cause. Honor, also, to the citizen who cares for his brother in the field and serves, as he best can, the same cause.”

“We can complain because rose bushes have thorns, or rejoice because thorn bushes have roses.”

“I don't like that man. I must get to know him better.”

“I went to my room one day and locked the door and got down upon my knees before Almighty God and prayed to Him mightily for victory at Gettysburg. I told Him that this war was His, and our cause His cause, that we could not stand another Fredericksburg or Chancellorsville. Then and there I made a solemn vow to Almighty God that if He would stand by our boys at Gettysburg, I would stand by Him, and He did stand by you boys, and I will stand by him. And after that, I don't know how it was, and I cannot explain it, soon a sweet comfort crept into my soul. The feeling came that God had taken the whole business into His own hands, and things would go right at Gettysburg, and that was why I had no fears about you.”

“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.”

“The world has never had a good definition of the word liberty, and the American people, just now, are much in want of one. We all declare for liberty; but in using the same word we do not all mean the same thing. With some the word liberty may mean for each man to do as he pleases with himself, and the product of his labor; while with others the same word may mean for some men to do as they please with other men, and the product of other men’s labor. Here are two, not only different, but incompatible things, called by the same name, liberty. And it follows that each of the things is, by the respective parties, called by two different and incompatible names, liberty and tyranny. The shepherd drives the wolf from the sheep’s throat, for which the sheep thanks the shepherd as a liberator, while the wolf denounces him for the same act as the destroyer of liberty, especially as the sheep was a black one. Plainly the sheep and the wolf are not agreed upon a definition of the word liberty.”
