But this information about the brain seems to suggest that not only will we never know what is truly real, but that because of the very nature of the brain itself, we can never know what's really real. Of course, this is based on what we know of the brain, and if we can't really know anything...and this line of reasoning might be of great importance, and it might (probably is, I think) be pure and pointless sophistry, but how can we (and can we) know? I would have like to see more information about the sensory deprivation chamber and how that affects the brain. I don't know if the research simply isn't available, or if Wolfe didn't see the relevance in regards to his discussion of humans as Homo loquax, but simply extrapolating from the scant mention he makes of it might have been sufficient. For instance, how would, or...

I don't think these are things, though, that can ever truly be known -- though whether that is a result of the physical realities of the brain, the metaphysical limitations of speech, or a complex relationship between the two, I cannot really say.
