The child is immediately placed into the most extreme of sensory deprivation environments and simply hooked up to life-sustaining equipment and raised to adulthood. He can't hear anything, see anything, move or feel anything etc.
Does this human being have a mind? My answer would be no, because a mind can only be defined in terms of a suite of interactive relationships between an individual and its external environment. I suspect that such a being would still have an internal bodily environment which it would be able to sense but it seems unlikely that in the absence of an external referential frame this would in any sense constitute an awareness of self. Agree or disagree?
Agree. To start there's no language, nor any need for it. What level of sentience can be achieved when only internal processes can be perceived?
There's a somewhat related case, where an autistic girl finally cracked the language barrier in her teens, communicating with one finger typing. Until then, everyone including her parents assumed that she had no mind. It turned out that she was every bit as aware as any other child. Shockingly so. She was actually bright, perceptive and wise beyond her years. Her father tearfully remembered all the times he'd spoken about her in front of her as though she wasn't aware. A touching understanding between them followed.
When the girl had strange spams, it was actually a completely normal response for a person afflicted with terrible physical sensations, one that she said felt like being stung all over her arms (that weird arm slapping of autistic people finally has a reason). It seems so much of their inappropriate reactions are due to sudden overwhelming bursts of pain. It makes the sudden shouts understandable.
Imagine that - stuck in a body while thinking normally and experiencing frequent intense pains that make you behave in embarrassing and incomprehensible ways. As a result people treat you like you as though you are mindless and there's nothing you can say or do to make yourself understood.
