“The fact that a believer is happier than a skeptic is no more to the point than the fact that a drunken man is happier than a sober one. The happiness of credulity is a cheap and dangerous quality of happiness, and by no means a necessity of life.”

“We have no more right to consume happiness without producing it than to consume wealth without producing it.”

“A life spent making mistakes is not only more honorable, but more useful than a life spent doing nothing.”

“A gentleman is one who puts more into the world than he takes out.”

“Beware of false knowledge; it is more dangerous than ignorance.”

“The secret of being miserable is to have leisure to bother about whether you are happy or not. The cure for it is occupation, because occupation means pre-occupation; and the pre-occupied person is neither happy nor unhappy, but simply alive and active. That is why it is necessary to happiness that one should be tired.”

“Life does not cease to be funny when people die any more than it ceases to be serious when people laugh.”
