I'm not sure if this warrants a whole new thread, but anyway. . .

I was intrigued by what Avy said about dreaming with languageless thoughts and got to thinking about how one actually thinks without language. I can't speak for everyone else, but when I think, I basically hear the words in my mind. But how would someone, say a person that was raised by wolves, think? Obviously there are wordless feelings and impulses, but does this constitute thought? Also, does a deaf person think by mentally seeing sign language or the written word? In what manner did Helen Keller think?
