A generation which ignores history has no past — and no future. - Robert A. Heinlein

Mass psychology is not simply a summation of individual psychologies; that is a prime theorem of social psychodynamics—not just my opinion; no exception has ever been found to this theorem. It is the social mass-action rule, the mob-hysteria law, known and used by military, political, and religious leaders, by advertising men and prophets and propagandists, by rabble rousers and actors and gang leaders, for generations before it was formulated in mathematical symbols. It works.

"I've found out why people laugh. They laugh because it hurts so much... because it's the only thing that'll make it stop hurting"
...
But that's not all people laugh at."
Isn't it? Perhaps I don't grok all its fullness yet. But find me something that really makes you laugh sweetheart... a joke, or anything else- but something that gave you a a real belly laugh, not a smile.

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.
