“If I were two-faced, would I be wearing this one?”

“No man has a good enough memory to be a successful liar”

“With malice toward none, with charity for all, with firmness in the right as God gives us to see the right, let us strive on to finish the work we are in, to bind up the nation's wounds, to care for him who shall have borne the battle and for his widow and his orphan, to do all which may achieve and cherish a just and lasting peace among ourselves and with all nations.”

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

“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.” 

“The loss of enemies does not compensate for the loss of friends.”

“The legitimate object of government is to do for a community of people whatever they need to have done, but can not do at all, or can not so well do, for themselves – in their separate, and individual capacities.”

“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.”

“No man is poor who has a Godly mother.”

“It is the eternal struggle between these two principles — right and wrong — throughout the world. They are the two principles that have stood face to face from the beginning of time; and will ever continue to struggle. The one is the common right of humanity, and the other the divine right of kings. It is the same principle in whatever shape it develops itself. It is the same spirit that says, "You toil and work and earn bread, and I'll eat it." No matter in what shape it comes, whether from the mouth of a king who seeks to bestride the people of his own nation and live by the fruit of their labor, or from one race of men as an apology for enslaving another race, it is the same tyrannical principle.”

“Don't give up. Come on. Just keep on trying. Don't frown. Smile! You can do it. If you just try a little harder. I've got a feeling this whole thing might just work out okay. You'll see. Don't give up. Tomorrow is a brand new day. Now I want to see all of you get up on your feet and look like you're enjoying yourselves. Come on, let's see some of that famous ‘Pennsylvania optimism’ I've heard so much about..." [Excerpted from the recently discovered preamble to Gettysburg Address]”

“It's not me who can't keep a secret. It's the people I tell that can't.”

“I can see how it might be possible for a man to look down upon the earth and be an atheist, but I cannot conceive how a man could look up into the heavens and say there is no God.”

“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.”

“Don't worry when you are not recognized but strive to be worthy of recognition”
