Well, in the first place an armed society is a polite society. Manners are good when one may have to back up his acts with his life. For me, politeness is a sine qua non of civilization. That’s a personal evaluation only. But gunfighting has a strong biological use. We do not have enough things to kill off the weak and the stupid these days. But to stay alive as an armed citizen a man has to be either quick with his wits or with his hands, preferably both. It’s a good thing.
— Robert A. Heinlein
