“It was not by making yourself heard but by staying sane that you carried on the human heritage.”

“Maybe this was how you stayed sane in wartime: a handful of noble deeds amid the chaos.”

“The only way to stay sane is to go a little crazy.”

“Geraldine: I'm quite sane!
Rance: Pull yourself together. Why have you been certified if you're sane? Even for a madwoman you're unusually dense.”

“Tradition and heritage are all dead people's baggage, stop carrying it. Move forward.”

“You can go through your whole life telling yourself that life is logical, life is prosaic, life is sane. Above all, sane. And I think it is. I've had a lot of time to think about that.”

“It didn't matter what you looked like. It was how you carried yourself, how you saw yourself.”

“What does it mean to be crazy? To have a disorder of the mind. But "disorder" can only exist if there is some kind of pre determined "order" set in place. And who decides on order relative to the human mind? Human society. Sane and insane is a judgment based on perspective. And according to many other perspectives within this universe, it is human society that is rampant with disorder. So there is no reason to think of yourself as insane; if the very mindset of the society that determines whether you are sane or insane… is in and of itself insane!”

“Life's single lesson: that there is more accident to it than a man can ever admit to in a lifetime and stay sane.”
