“The best way to get a bad law repealed is to enforce it strictly.”

“If you think you can you can, if you think you can't you're right!”

“I am not bound to win, but I am bound to be true. I am not bound to succeed, but I am bound to live by the light that I have. I must stand with anybody that stands right, and stand with him while he is right, and part with him when he goes wrong.”

“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.”

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

“When you reach the end of your rope, tie a knot and hang on”

“A nation that does not honor its heroes will not long endure.”

“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”

“Education does not mean teaching people what they do not know. It means teaching them to behave as they do not behave.”

“The will of God prevails. In great contests each party claims to act in accordance with the will of God. Both may be, and one must be, wrong.”

“I consider the central idea pervading this struggle is the necessity that is upon us, of proving that popular govenment is not an absurdity. We must settle this question now, whether in a free government the minority have the right to break up the govenment whenever they choose. If we fail it will go far to prove the incapability of the people to govern themselves.”

“When you have got an elephant by the hind legs and he is trying to run away. it's best to let him run"

“Slavery is founded in the selfishness of man's nature, opposition to it in his love of justice. These principles are an eternal antagonism, and when brought into collision so fiercely as slavery extension brings them, shocks and throes and convulsions must ceaselessly follow.”

“I know not how to aid you, save in the assurance of one of mature age, and much severe experience, that you can not fail, if you resolutely determine, that you will not.”
