Each of you, for himself, by himself and on his own responsibility, must speak. And it is a solemn and weighty responsibility, and not lightly to be flung aside at the bullying of pulpit, press, government, or the empty catch-phrases of politicians. Each must for himself alone decide what is right and what is wrong, and which course is patriotic and which isn't. You cannot shirk this and be a man. To decide it against your convictions is to be an unqualified and inexcusable traitor, both to yourself and to your country, let men label you as they may. If you alone of all the nation shall decide one way, and that way be the right way according to your convictions of the right, you have done your duty by yourself and by your country — hold up your head! You have nothing to be ashamed of.

Everyone is a moon and has a dark side which he never shows to anybody.
¶ Following the Equator, ch. 66 (1897)
There are several good protections against temptations, but the surest is cowardice.
¶ Following the Equator (1897)
We despise all reverences and all objects of reverence which are outside the pale of our list of sacred things. And yet, with strange inconsistency, we are shocked when other people despise and defile the things which are holy to us.
¶ Following the Equator (1897)
There are many humorous things in the world, among them the white man's notion that he is less savage than the other savages.
¶ Following the Equator (1897)
We should be careful to get out of an experience only the wisdom that is in it — and stop there; lest we be like the cat that sits down on a hot stove-lid. She will never sit down on a hot stove-lid again — and that is well; but also she will never sit down on a cold one anymore.
¶ Following the Equator, ch. 11 (1897)
I was gratified to be able to answer promptly, and I did. I said I didn't know.
¶ Life on the Mississippi, ch. 6 (1883)
Courage is resistance to fear, mastery of fear -- not absence of fear. Except a creature be part coward it is not a compliment to say it is brave.

¶ Pudd'nhead Wilson (1894)
The holy passion of friendship is so sweet and steady and loyal and enduring in nature that it will last through a whole lifetime, if not asked to lend money.
¶ Pudd'nhead Wilson, "Pudd'nhead Wilson's Calendar"
If he had been a great and wise philosopher, like the writer of this book, he would now have comprehended that Work consists of whatever a body is obliged to do and that Play consists of whatever a body is not obliged to do.
¶ The Adventures of Tom Sawyer, ch. 2 (1876)
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 attain. If he had been a great and wise philosopher, like the writer of this book, he would now have comprehended that Work consists of whatever a body is obliged to do, and that Play consists of whatever a body is not obliged to do. And this would help him to understand why constructing artificial flowers or performing on a tread-mill is work, while rolling ten-pins or climbing Mont Blanc is only amusement.
¶ The Adventures of Tom Sawyer, ch. 2 (1876)
Travel is fatal to prejudice, bigotry, and narrow-mindedness, and many of our people need it sorely on these accounts.
