ah, no, i'm all about thinking
however, i think Descartes is wrong when he says: i think therefore i am
i think he should have stopped at: thinking
the whole concept of "i" is learned
one example is feral children, who grow up without contact to other humans. they don't have self-awareness. so this self-awareness stuff is not natural, it is what others, who were taught in it, teach their children.
it is like someone creates a name of his computer, and begins to treat his computer as a person, and then the computer will look as a person, to some extend, because this personality was projected in it
with brains - i.e. neuro-nets - it's even easier, because they are more plastic. if you communicate with a brain as if it is supposed to form a "self", it does. this even works with animals, check the most recent studies on primate language acquisition and intelligence. you can train a monkey to have moods, and sometimes it will say to be sad or happy, depending on circumstances etc. but if you don't teach it - it won't
anyway, the main point is that we take this most fundamental thing for granted, it's everywhere in our language, in all forms of communication, but it's not something natural or fixed.
