“I will, to the best of my ability, preserve, protect and defend the Constitution of the United States. It is not the Constitution as I would like to have it, but as it is, that is to be defended. The Constitution will not be preserved & defended until it is enforced & obeyed in every part of every one of the United States. It must be so respected, obeyed, enforced and defended, and let the grass grow where it may.”

“The way for a young man to rise is to improve himself every way he can, never suspecting that anybody wishes to hinder him. Allow me to assure you that suspicion and jealousy never did help any man in any situation. There may sometimes be ungenerous attempts to keep a young man down; and they will succeed, too, if he allows his mind to be diverted from its true channel to brood over the attempted injury. Cast about and see if this feeling has not injured every person you have ever known to fall into it.”

“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”

“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.”

“He can compress the most words into the smallest ideas of any man I ever met.”

“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.”

“I'm a success today because I had a friend who believed in me and I didn't have the heart to let him down.”

“In your temporary failure there is no evidence that you may not yet be a better scholar, and a more successful man in the great struggle of life, than many others, who have entered college more easily.”

“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.”
