Number one, I don't believe, requires much explanation. Never be cruel means, of course, always be kind. I believe that kindness is the natural human instinct, not cruelty. I have no illusions about humanity. I know its faults, its frequent blindness, its capacity for making terrible mistakes. But my work as a writer takes me among all kinds of men and women, often the very rough and the very poor. Everywhere, I have found generosity and nobility men who would have gladly given their lives for me, because I had done them some slight kindness.
