“Your own resolution to succeed is more important than any other”

“I am slow to learn and slow to forget that which I have learned. My mind is like a piece of steel, very hard to scratch any thing on it and almost impossible after you get it there to rub it out.”

“The Bible is not my book nor Christianity my profession. I could never give assent to the long, complicated statements of Christian dogma.”

“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 you think you can you can, if you think you can't you're right!”

“You cannot build character and courage by taking away people's initiative and independence”

“There's no honorable way to kill, no gentle way to destroy. There is nothing good in war. Except its ending.”

“People who like this sort of thing will find this the sort of thing they like.

“Nothing will divert me from my purpose.”

“You can fool some of the people all of the time, and all of the people some of the time, but you can’t fool all of the people all of the time.”

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

“Don't give up. Come on. Just keep on trying. Don't frown. Smile! You can do it. If you just try a little harder. I've got a feeling this whole thing might just work out okay. You'll see. Don't give up. Tomorrow is a brand new day. Now I want to see all of you get up on your feet and look like you're enjoying yourselves. Come on, let's see some of that famous ‘Pennsylvania optimism’ I've heard so much about..." --from the recently discovered preamble to Gettysburg Address”

“If any man at this day sincerely believes that a proper division of local from federal authority, or any part of the Constitution, forbids the Federal Government to control as to slavery in the federal territories, he is right to say so, and to enforce his position by all truthful evidence and fair argument which he can. But he has no right to mislead others, who have less access to history, and less leisure to study it, into the false belief that "our fathers who framed the Government under which we live" were of the same opinion - thus substituting falsehood and deception for truthful evidence and fair argument.”

“You may deceive all the people part of the time, and part of the people all the time, but not all the people all the time.”

“I am approached with the most opposite opinions and advice, and that by religious men, who are equally certain that they represent the Divine will. I am sure that either the one or the other is mistaken in that belief, and perhaps in some respects both. I hope it will not be irreverent for me to say that if it is probable that God would reveal his will to others, on a point so connected with my duty, it might be supposed he would reveal it directly to me; for, unless I am more deceived in myself than I often am, it is my earnest desire to know the will of Providence in this matter. And if I can learn what it is, I will do it! These are not, however, the days of miracles, and I suppose it will be granted that I am not to expect a direct revelation. I must study the plain, physical facts of the case, ascertain what is possible and learn what appears to be wise and right.”
