“To believe in the things you can see and touch is no belief at all - but to believe in the unseen is a triumph and a blessing.”

“...THAT FROM THESE HONORED DEAD WE TAKE INCREASED DEVOTION TO THAT CAUSE FOR WHICH THEY GAVE THE LAST FULL MEASURE OF DEVOTION;...”

“IF you are going to fight, don't let them talk you into negotiating. But, if you are going to negotiate, don't let them talk you into fighting.”

“Every man's happiness is his own responsibility.”

“A house divided against itself cannot stand." I believe this government cannot endure, permanently half slave and half free. I do not expect the Union to be dissolved — I do not expect the house to fall — but I do expect it will cease to be divided. It will become all one thing or all the other.”

“If Friendship is your weakest point, you are the strongest person in the world.”

“Commitment is what transforms a promise into reality.”

“Our progress in degeneracy appears to me to be pretty rapid. 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.”

“Our safety, our liberty, depends upon preserving the Constitution of the United States as our fathers made it inviolate. The people of the United States are the rightful masters of both Congress and the courts, not to overthrow the Constitution, but to overthrow the men who pervert the Constitution.”

“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.”

“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.”

“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.”

“you can fool some of the people all of the time and all of the people some of the time but you cannot fool all of the people all of the time”

“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.” 

“I remember my mother's prayers and they have always followed me. They have clung to me all my life.”
