So just how did the brain come into existence physically? ... To exploit an available resource perhaps? Which, I think is the whole point, why does anything evolve, if not to exploit the resources at hand? Why did our eyes elvolve, if not to exploit the available source of light? What would be the difference between that and say designing an amplifier in order to reproduce sound? Wouldn't it be fair to say that the amplifier exists solely to reproduce the sound? So why should it be any different with the brain which, is just a means by which to capture/contain consciousness?
