Mark Twain

“The fact that man knows right from wrong proves his intellectual superiority to the other creatures; but the fact that he can do wrong proves his moral inferiority to any creature that cannot.”

“There isn't time — so brief is life — for bickerings, apologies, heartburnings, callings to account. There is only time for loving — and but an instant, so to speak, for that.”

“Fame is a vapor; popularity an accident; the only earthly certainty is oblivion.”

“Education consists mainly in what we have unlearned.”

“You can't depend on your eyes when your imagination is out of focus.”

“Patriotism is supporting your country all the time, but your government only when it deserves it.”

“Nothing that grieves us can be called little: by the eternal laws of proportion a child's loss of a doll and a king's loss of a crown are events of the same size.”

“He had discovered a great law of human action, without knowing it — namely, that in order to make a man or a boy covet a thing, it is only necessary to make the thing difficult to obtain.”

“Prosperity is the best protector of principle.”

“When in doubt, tell the truth.”

“Travel is fatal to prejudice, bigotry, and narrow-mindedness, and many of our people need it sorely on these accounts.”
