I believe the brain is an outcropping of our nervous systems. It
has gained dominance over the rest of our nervous system but it
is integrally a part of it.
I don't believe the "self" stops at the skin either.
We are connected physically, tangibly, perhaps even measureably,
right now, right here.
Through communication. I see communication as a physical process
that utilizes Time in a flexible fashion.
If you and I, William, were part of an organism, which I
somewhat believe we are, my sensory output and your sensory
inputs and feedback loops are physically connected.
The lag inbetween is, ultimately iinconsequential to the
organism.
So I suppose, I do believe in a slime-mold view of humanity or
life in general as an organism that has existed for a very long
time indeed.
