"What is the purpose of houses? It is to protect us from the wind and cold of winter, the heat and rain of summer, and to keep out robbers and thieves. Once these ends have been secured, that is all. Whatever does not contribute to these ends should be eliminated."

“The murder of one person is called unrighteous and incurs one death penalty. Following this argument, the murder of ten persons will be ten times as unrighteous and there should be ten death penalties; the murder of a hundred persons will be a hundred times as unrighteous and there should be a hundred death penalties. All the gentlemen of the world know that they should condemn these things, calling them unrighteous. But when it comes to the great unrighteousness of attacking states, they do not know that they should condemn it. On the contrary, they applaud it, calling it righteous.”
