It's a myth that crazy people don't know they're crazy. Many of us are surely as capable of epiphany and introspection as anyone else, maybe more so. I suspect we spend far more time thinking about our thoughts than do sane people.

Perhaps if you know you are insane then you are not insane.

Because that’s really something I can’t stand — when people refer to themselves as crazy. The truly crazy are labeled so on the grounds that they see nothing wrong with their behavior. They forge ahead, lighting fires in public buildings and defecating in frying pans without the slightest notion that they are out of step with the rest of society. That, to me, is crazy.

Initially, he worried that he might be going crazy. But then he decided if you felt you were crazy you weren't really crazy because he had heard somewhere that crazy people didn't know they were insane.

Is everyone really crazy but me?

...everybody thinks I'm crazy, but I'm not. I know-every crazy person says that, but really, there's nothing wrong with my head. If only God would make me crazy! It's my heart that's sick, not my head, and there's no cure for that. ("Crazy")

Crazy people are not crazy if one accepts their reasoning.

I don't think I've gone insane. If I’m seen enough to be worried about my sanity, how crazy can I be? Or am I just fooling myself?

A question that sometimes drives me hazy: am I or are the others crazy?

I am crazy, I know, Thérèse. But who is not?

I'm not crazy. My reality is just different than yours.

Don’t worry if they say you’re crazy. They said that about me and yet I was saner than all of them. I knew. No matter. You know. Insane or sane, you know. It’s a good thing to know - no matter what they call it.

What sane person could live in this world and not be crazy?

I'm very eccentric. I do everything excessively. Maybe some people tell me I'm crazy. Others maybe say I'm vain. Others say something else, but everyone is wrong. I'm not crazy.
