“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.”

“Allow the President to invade a neighboring nation, whenever he shall deem it necessary to repel an invasion and you allow him to do so whenever he may choose to say he deems it necessary for such purpose -- and you allow him to make war at pleasure. . . . If, today, he should choose to say he thinks it necessary to invade Canada to prevent the British from invading us, how could you stop him? You may say to him, 'I see no probability of the British invading us'; but he will say to you, 'Be silent; I see it, if you don't.”

“You cannot escape the responsibility of tomorrow by evading it today.”

“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 now leave, not knowing when or whether I may return, to a task before me greater than that which rested upon Washington. Without the assistance of that Divine Being who ever attended him, I cannot succeed. With that assistance, I cannot fail. Trusting in Him, who can go with me, and remain with you and be everywhere for good, let us confidently hope that all will yet be well. To His care commending you, as I hope in your prayers you will commend me, I bid you an affectionate farewell.”

“The dogmas of the quiet past are inadequate to the stormy present. The occasion is piled high with difficulty and we must rise with the occasion. As our case is new, we must think anew and act anew. We must disenthrall ourselves, and then we shall save our country.”

“We have been the recipients of the choicest bounties of Heaven; we have been preserved these many years in peace and prosperity; we have grown in numbers, wealth, and power. … But we have forgotten God. We have forgotten the gracious hand which preserved us in peace and multiplied and enriched and strengthened us, and we have vainly imagined, in the deceitfulness of our hearts, that all these blessings were produced by some superior wisdom and virtue of our own. Intoxicated with unbroken success, we have become too self-sufficient to feel the necessity of redeeming and preserving grace, too proud to pray to the God that made us. (“A National Day of Fasting, Humiliation, and Prayer.” Proclamation March 30, 1863)”

“If you would win a man to your cause, first convince him that you are his sincere friend.”

“Character is like a tree and reputation its shadow. The shadow is what we think it is and the tree is the real thing.”

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

“Хората са толкова щастливи, колкото съзнанието им позволява.”

“You can fool some of the people all of the time, and all of the people some of the time, but you can not fool all of the people all of the time.”
