But this may be a matter of taste. Some shamans think that it is better to be killed in a war, or to die in childbirth, or to starve in misery, than never to have lived at all. They may be right. But I don't have to like it —and I don't.

“I beg your pardon, sir,” Thomas apologized sincerely. “Nevertheless, I wish there were some way for me to do something for you.”
“That is another matter. Help your brother when you can, and help will come to you when you need it.”

You can sway a thousand men by appealing to their prejudices quicker than you can convince one man by logic.
