“If any man tells you he loves America, yet hates labor, he is a liar. If any man tells you he trusts America, yet fears labor, he is a fool.”

“I have come to the conclusion never again to think of marrying, and for this reason, I can never be satisfied with anyone who would be blockhead enough to have me.”

“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 wll ever to struggle.”

“The world has never had a good definition of the word liberty, and the American people, just now, are much in want of one. We all declare for liberty; but in using the same word we do not all mean the same thing. With some the word liberty may mean for each man to do as he pleases with himself, and the product of his labor; while with others the same word may mean for some men to do as they please with other men, and the product of other men’s labor. Here are two, not only different, but incompatible things, called by the same name, liberty. And it follows that each of the things is, by the respective parties, called by two different and incompatible names, liberty and tyranny. The shepherd drives the wolf from the sheep’s throat, for which the sheep thanks the shepherd as a liberator, while the wolf denounces him for the same act as the destroyer of liberty, especially as the sheep was a black one. Plainly the sheep and the wolf are not agreed upon a definition of the word liberty.”

“Allow me to assure you it is a perfect certainty that you will, very soon, feel better - quite happy - if you only stick to the resolution you have taken to procure a military education. I am older than you, have felt badly myself, and know, what I tell you is true. Adhere to your purpose and you will soon feel as well as you ever did. On the contrary, if you falter, and give up, you will lose the power of keeping any resolution, and will regret it all you life.”

“Those who write clearly have readers, those who write obscurely have commentators.”

“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.” 

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

“My earlier views of the unsoundness of the Christian scheme of salvation and the human origin of the scriptures have become clearer and stronger with advancing years, and I see no reason for thinking I shall ever change them.”

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

“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 progress in degeneracy appears to me to be pretty rapid. 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.”

“To remain as I am is impossible; I must die or be better, it appears to me.”

“And this, too, shall pass away.”

“If friendship is your weakest point, then you are the strongest person in the world.”
