“A half effort is a wasted effort.”

“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.” 

“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.”

“Whatever you are be a good one.”

“Our safety, our liberty, depends upon preserving the Constitution of the United States as our fathers made it inviolate. The people of the United States are the rightful masters of both Congress and the courts, not to overthrow the Constitution, but to overthrow the men who pervert the Constitution.”

“A universal feeling, whether well or ill-founded cannot be safely disregarded.”

“There can be glory in failure and despair in success.”

“I may be wrong in regard to any or all of them; but holding it a sound maxim, that it is better to be only sometimes right, than at all times wrong, so soon as I discover my opinions to be erroneous, I shall be ready to renounce them.”

“It often requires more courage to dare to do right than to fear to do wrong.”

“The most altruistic man is the most selfish.”

“Give me six hours to chop down a tree and I will spend the first four sharpening the axe.”

“The best way to predict your future is to create it.”

“Writing, the art of communicating thoughts to the mind through the eye, is the great invention of the world...enabling us to converse with the dead, the absent, and the unborn, at all distances of time and space.”

“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.”

“In great contests each party claims to act in accordance with the will of God. Both may be, and one must be wrong. God cannot be for, and against the same thing at the same time.”
