Mark Twain

"I was gratified to be able to answer promptly, and I did. I said I didn’t know."
"A person that started in to carry a cat home by the tail was gitting knowledge that was always going to be useful to him, and warn't ever going to grow dim or doubtful."
"A lie can travel half way around the world while the truth is putting on its shoes."
"In a good bookroom you feel in some mysterious way that you are absorbing the wisdom contained in all the books through your skin, without even opening them."
"The easy confidence with which I know another man's religion is folly teaches me to suspect that my own is also."
"The man who does not read has no advantage over the man who cannot read."
"There are many humorous things in the world; among them, the white man's notion that he is less savage than the other savages."
"Travel is fatal to prejudice, bigotry, and narrow-mindedness, and many of our people need it sorely on these accounts. Broad, wholesome, charitable views of men and things cannot be acquired by vegetating in one little corner of the earth all one's lifetime."
"Keep away from people who try to belittle your ambitions. Small people always do that, but the really great make you feel that you, too, can become great."
"Peace by persuasion has a pleasant sound, but I think we should not be able to work it. We should have to tame the human race first, and history seems to show that that cannot be done."
"I have never let my schooling interfere with my education."
"Thunder is good, thunder is impressive; but it is lightning that does the work."
