“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.”

“As a nation, we began by declaring that 'all men are created equal.' We now practically read it 'all men are created equal, except negroes.' When the Know-Nothings get control, it will read 'all men are created equal, except negroes, and foreigners, and Catholics.' When it comes to this I should prefer emigrating to some country where they make no pretense of loving liberty – to Russia, for instance, where despotism can be taken pure, and without the base alloy of hypocrisy.”

“Let not him who is houseless pull down the house of another, but let him work diligently and build one for himself, thus by example assuring that his own shall be safe from violence when built.”

“It is said an Eastern monarch once charged his wise men to invent him a sentence to be ever in view, and which should be true and appropriate in all times and situations. They presented him the words, "And this too, shall pass away." How much it expresses! How chastening in the hour of pride! How consoling in the depths of affliction!”

“Investment in knowledge pays the best interest.”

“Gentlemen, why do you not laugh? With the fearful strain that is upon me day and night, if I did not laugh, I should die. ”

“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.”
