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

“A capacity, and taste, for reading, gives access to whatever has already been discovered by others. It is the key, or one of the keys, to the already solved problems. And not only so. It gives a relish, and facility, for successfully pursuing the [yet] unsolved ones.”

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

“All I have learned, I learned from books.”

“You can’t make a weak man strong by making a strong man weak”

“Whenever I hear anyone arguing for slavery, I feel a strong impulse to see it tried on him personally.”

“From whence shall we expect the approach of danger? Shall some trans-Atlantic military giant step the earth and crush us at a blow? Never. All the armies of Europe and Asia...could not by force take a drink from the Ohio River or make a track on the Blue Ridge in the trial of a thousand years. No, if destruction be our lot we must ourselves be its author and finisher. As a nation of free men we will live forever or die by suicide.”

“With educated people, I suppose, punctuation is a matter of rule; with me it is a matter of feeling. But I must say I have a great respect for the semicolin; it's a useful little chap”

“A half effort is a wasted effort.”

“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.”

“If slavery is not wrong, nothing is wrong.”

“Anybody will do for you, but not for me. I must have somebody.”

“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.”

“Be with a leader when he is right, stay with him when he is still right, but, leave him when he is wrong.”

“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.”
