Habit is habit, and not to be flung out of the window by any man, but coaxed down-stairs one step at a time. - Mark Twain

Let us consider that we are all partially insane. It will explain us to each other; it will unriddle many riddles; it will make clear and simple many things which are involved in haunting and harassing difficulties and obscurities now.

The man who is a pessimist before 48 knows too much; if he is an optimist after it he knows too little.

I wanted to damage every man in the place, and every woman--and not in their bodies or in their estate, but in their vanity--the place where feeble and foolish people are most vulnerable. So I disguised myself and came back and studied you. You were easy game. You had an old and lofty reputation for honesty, and naturally you were proud of it — it was your treasure of treasures, the very apple of your eye. As soon as I found out that you carefully and vigilantly kept yourselves and your children out of temptation, I knew how to proceed. Why, you simple creatures, the weakest of all weak things is a virtue which has not been tested in the fire.
