From my limited knowledge of the physics of the human Eye.. I got the impression that the
image enters the brain via optic nerve which I always assumed to be an electrical impulse
circuit. But if this were indeed the case, vision interpretation would be purely a psych/brain
function. The question I have is this: Has a human *ever* seen the real world?
Bizarre question, an electrical impulse from a nerve to the brain is NOT true vision but
rather something the brain perceives, interprets as sight. I guess the same could be true
of the other senses as well... hearing, touch, taste, etc are just signals that the brain
interprets. I am no biology expert, but science teaches me these things that my simple brain
has a hard time accepting or fully understanding.
Thanks,
