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

“In giving freedom to the slave, we assure freedom to the free -- honorable alike in what we give, and what we preserve. We shall nobly save, or meanly lose, the last best hope of earth”

“We shall need all the anti-slavery feeling in the country, and more; you can go home and try to bring the people to your views, and you may say anything you like about me, if that will help... When the hour comes for dealing with slavery, I trust I will be willing to do my duty though it cost my life.”

“I fear you do not fully comprehend the danger of abridging the liberties of the people. Nothing but the very sternest necessity can ever justify it. A government had better go to the very extreme of toleration, than to do aught that could be construed into an interference with, or to jeopardize in any degree, the common rights of its citizens.”

“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.” 

“He has a right to criticize, who has a heart to help.”

“A house divided cannot stand.”

“Whatever you are, be a good one.”

“Investment in knowledge pays the best interest.”

“I do the very best I know how, the very best I can, and I mean to keep on doing so until the end.”

“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.”

“I am in favor of animal rights as well as human rights. That is the way of a whole human being.”

“My concern is not whether God is on our side; my greatest concern is to be on God's side, for God is always right.”

“I have never studied the art of paying compliments to women; but I must say that if all that has been said by orators and poets since the creation of the world in praise of women were applied to the women of America, it would not do them justice for their conduct during this war.”

“Upon the subject of education, not presuming to dictate any plan or system respecting it, I can only say that I view it as the most important subject which we as a people can be engaged in.”
