“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.”

“To remain as I am is impossible; I must die or be better, it appears to me.”

“In your temporary failure there is no evidence that you may not yet be a better scholar, and a more successful man in the great struggle of life, than many others, who have entered college more easily.”

“The inclination to share thoughts with one another is probably an original impulse of our nature.If in pain I wish to let you know it,and ask your sympathy and assistance;and my pleasurable emotions also,I wish to communicate to,and share with you.”

“Don't interfere with anything in the Constitution. That must be maintained, for it is the only safeguard of our liberties.”

“Allow me to assure you it is a perfect certainty that you will, very soon, feel better - quite happy - if you only stick to the resolution you have taken to procure a military education. I am older than you, have felt badly myself, and know, what I tell you is true. Adhere to your purpose and you will soon feel as well as you ever did. On the contrary, if you falter, and give up, you will lose the power of keeping any resolution, and will regret it all you life.”

“I will not say that we may not sooner or later be compelled to meet force by force; but the time has not yet come, and if we are true to ourselves, may never come. Do not mistake that the ballot is stronger than the bullet. Therefore let the legions of slavery use bullets; but let us wait patiently till November, and fire ballots at them in return; and by that peaceful policy, I believe we shall ultimately win.”

“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.”

“When I get ready to talk to people, I spend two thirds of the time thinking what they want to hear and one third thinking about what I want to say.”
