So, after all, dualism is possible. the "I" seems to be no more a language convenience. It becames the substance.
That's right. 'I' becomes the substance. The idea is a thoroughly bad one.
First, by saying 'I' am here, and my brain is 'there', I have only extension - or one substance, so it would not be a dualism. But I can't say that I am here and my brain is there anyway, because that would mean that I would be inside a brain bag, and the brain is not a bag. There is nothing I can construct that I can call 'I' such that I can distinguish it from a material brain.
The answer is that 'I' is a grammatical convenience, which cannot be influenced by the brain. But this also means that the brain is limited as a concept because it fails to support consciousness. So we must abandon the idea of the brain. This is easy to do if we remember that the brain is a theoretical construction (to be precise, a paradigmatic oxymoron, a conceptual hybrid) assembled from social criteria mapped to chemical events.
