As Some Kind of Stranger said, but the phrase, 'the human attributes of conscious self-awareness and free will are evidence of the human soul and will never be fully defined by molecular activity in the brain', stands out.
How on earth do you know that? For one thing, it's clear that the brain operates in terms of modules or specializations, so for example, some kinds of brain damage produce loss of speech (aphasia). There is also a kind of holistic operation as well, where different modules interact.
I would think that there is optimism among neurologists and psychologists that the link between brain and consciousness will one day be understood.
