“Better to remain silent and be thought a fool than to speak out and remove all doubt.”

“They [the signers of the Declaration of Independence] did not mean to assert the obvious untruth that all were then actually enjoying that equality, nor yet that they were about to confer it immediately upon them. In fact, they had no power to confer such a boon. They meant simply to declare the right; so that the enforcement of it might follow as fast as circumstances should permit.”

“The facts with which I shall deal this evening are mainly old and familiar; nor is there anything new in the general use I shall make of them. If there shall be any novelty, it will be in the mode of presenting the facts, and the inferences and observations following that presentation.

“In regards to this great Book [the Bible], I have but to say it is the best gift God has given to man. All the good the Savior gave to the world was communicated through this Book.

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

“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.”

“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.” 

“No man who is resolved to make the most of himself can spare time for personal contention.”

“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 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.”

“Republicans are for both the man and the dollar, but in case of conflict the man before the dollar.”

“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.”

“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 up to what light I have.”

“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.”

“He whose wisdom surpasses that of all philosophers, has declared that 'a house divided against itself cannot stand”
