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

“In regards to this great Book [the Bible], I have but to say it is the best gift God has given to man. All the good the Savior gave to the world was communicated through this Book. But for it we could not know right from wrong. All things most desirable for man's welfare, here and hereafter, are found portrayed in it.”

“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 this government of the people, by the people, for the people, shall not perish from the earth.”

“I have seen your dispatch expressing your unwillingness to break your hold where you are. Neither am I willing. Hold on with a bulldog grip, and chew and choke...”

“Any people anywhere, being inclined and having the power, have the right to rise up, and shake off the existing government, and form a new one that suits them better. This is a most valuable - a most sacred right - a right, which we hope and believe, is to liberate the world.”

“I do the very best I know how—the very best I can; and I mean to keep doing so until the end. If the end brings me out all right, what is said against me won’t amount to anything. If the end brings me out wrong, ten angels swearing I was right would make no difference.”

“If you once forfeit the confidence of your fellow citizens, you can never regain their respect and esteem. It is true that you may fool all of the people some of the time; you can even fool some of the people all of the time; but you can't fool all of the people all of the time. -Speech at Clinton, Illinois, September 8, 1854.”

“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.”

“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.” 

“Those who look for the bad in people will surely find it.”

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

“It's not me who can't keep a secret. It's the people I tell that can't.”

“As our case is new, we must think and act anew.”

“I am growing old enough not to care much for the MANNER of doing things.”

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