This discussion seems to be wandering far from anything to do with
neuroscience or medical physics. How about taking it to a more
appropriate group? May I suggest sci.philosophy.meta, which is
oriented toward technical discussion of metaphysical issues? If you
want to follow this suggestion, just add a line to the header of your
responses, saying "Followups-to: sci.philosophy.meta", as I have done
with this post.
Many thanks,
