“How can you talk if you haven't got a brain?I don't know, but some people without brains do an awful lot of talking.”

“Scarecrow: I haven't got a brain... only straw. Dorothy: How can you talk if you haven't got a brain? Scarecrow: I don't know... But some people without brains do an awful lot of talking... don't they? Dorothy: Yes, I guess you're right.”

“Some people without brains do an awful lot of talking, don't you think?”

“The brain can be a dangerous thing. Even more so if you haven't got one.”

“And stop talking in that puffed-up way they taught you. Words aren't brains, you know.”

“Who knows what I want to do? Who knows what anyone wants to do? How can you be sure about something like that? Isn't it all a question of brain chemistry, signals going back and forth, electrical energy in the cortex? How do you know whether something is really what you want to do or just some kind of nerve impulse in the brain? Some minor little activity takes place somewhere in this unimportant place in one of the brain hemispheres and suddenly I want to go to Montana or I don't want to go to Montana. How do I know I really want to go and it isn't just some neurons firing or something? Maybe it's just an accidental flash in the medulla and suddenly there I am in Montana and I find out I really didn't want to go there in the first place. I can't control what happens in my brain, so how can I be sure what I want to do ten seconds from now, much less Montana next summer? It's all this activity in the brain and you don't know what's you as a person and what's some neuron that just happens to fire or just happens to misfire.”
