“If I were to try to read, much less answer, all the attacks made on me, this shop might as well be closed for any other business. 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's 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.”

“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.”

“Abraham Lincoln was asked by an aide about the church service he had attended. Lincoln responded that the minister was inspired, interesting, well-prepared, eloquent and the topic relevant. The aide said, “Then it was a good service?” Lincoln responded, “No.” The aide protested, “But, Mr. President, you said that the minister was inspired, interesting, well-prepared, eloquent, and that the topic was relevant.” “Yes,” replied Lincoln, “but he didn’t challenge us to do any great thing.”

“If this country is ever demoralized, it will come from trying to live without work.”
