Peace of mind is that mental condition in which you have accepted the worst.

Men resort to talking only when they haven't the power to enforce their convictions upon others.

In fact,I believe the reason why the Chinese failed to develop botany and zoology is that the Chinese scholar cannot stare coldly and unemotionally at a fish without immediately thinking of how it tastes in the mouth and wanting to eat it. The reason I don't trust Chinese surgeons is that I am afraid that when a Chinese surgeon cuts up my liver in search of a gall-stone, he may forget about the stone and put my liver in a frying pan.

The wisdom of life consists in the elimination of non-essentials.

I feel, like all modern Americans, no consciousness of sin and simply do not believe in it. All I know is that if God loves me only half as much as my mother does, he will not send me to Hell. That is a final fact of my inner consciousness, and for no religion could I deny its truth.

O wise humanity, terribly wise humanity! How inscrutable is the civilization where men toil and work and worry their hair gray to get a living and forget to play!

Nothing matters to a man who says nothing matters.
