I can't speak for everyone, because I am, unfortunately, not able to read minds, but I'm going to assume that most people are like myself in that we all think in literal terms. I mean, we all think in words, sentences and paragraphs. I do this all the time, I'll think of something as if I'm composing a letter. It actually bothers me sometimes, because I'll actually get caught on a word and stumble around trying to complete the thought even though the thought was already fully formed in my head. I'm only assuming that this is how most of us view the world and compose our thoughts; with language.
Something that jumped into my mind for some unknown reason is; How did Helen Keller think? I don't mean to imply that Helen Keller could not think, or was mentally inferior to others(quite the opposite in fact), but I cannot at all imagine how her brain must have worked. To have to piece the world together without a picture to go with it or a language to express it in. Of course, eventually sign language came into it, but that's still a stumbling block for me. She wouldn't have had a visual image to think with, or words to compose. I can't conceptualize how she must have seen the world and how her thought process must have worked. She wouldn't have had a visual image to think with, or words to compose.
