“Believing everyone is dangerous, but believing nobody is more dangerous.”

“Don't believe everything you read on the Internet.”

“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]”

“A woman is the only thing I am afraid of that I know will not hurt me.”

“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.”

“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.”

“A friend is one who has the same enemies as you have.”

“It will not do to investigate the subject of religion too closely, as it is apt to lead to infidelity.”

“And this, too, shall pass away.”
