Yet other scientists with equally impressive credentials are not so sure and are increasingly willing to consider a very different analogy – namely that the relationship of consciousness to the brain may be less like the relationship of the generator to the electricity it produces and more like the relationship of the TV signal to the TV set. In that case when the TV set is destroyed – dead – the signal still continues. Nothing in the present state of knowledge of neuroscience rules this revolutionary possibility out. True, if you damage certain areas of the brain certain areas of consciousness are compromised, but this does not prove that those areas of the brain generate the relevant areas of consciousness. If you were to damage certain areas of your TV set the picture would deteriorate or vanish but the TV signal would remain intact.
We are, in other words, confronted by at least as much mystery as fact around the subject of consciousness and this being the case we should remember that what seems obvious and self-evident to one generation may not seem at all obvious or self-evident to the next. For hundreds of years it was obvious and self-evident to the greatest human minds that the sun moved around the earth – one need only look to the sky, they said, to see the truth of this proposition. Indeed those who maintained the revolutionary view that the earth moved around the sun faced the Inquisition and death by burning at the stake. Yet as it turned out the revolutionaries were right and orthodoxy was terribly, ridiculously wrong.
The same may well prove to be true with the mystery of consciousness. Yes, it does seem obvious and self-evident that the brain produces it (the generator analogy), but this is a deduction from incomplete data and categorically NOT yet an established and irrefutable fact. New discoveries may force materialist science to rescind this theory in favour of something more like the TV analogy in which the brain comes to be understood as a transceiver rather than as a generator of consciousness and in which consciousness is recognized as fundamentally “non-local” in nature – perhaps even as one of the basic driving forces of the universe.
