Would you say, at least, that the brain is responsible for behavior?

This conversation was originally on the topic of artificial intelligence,
so whatever it is in us that leads to physical changes which manifest as
third-person observable behavior, do you believe that to be entirely
influenced by physical and (in theory) detectable matter/energy/fields?

If not, what mechanism do you theorize mediates between mental and physical
events?  Is it one way or two way?  If two way (or if as you often say it
is just the other side of the coin) then why not say it is physical?

If such a mechanism exists, it must conform to some set of laws, some rhyme
or reason, as otherwise how could the mental world (or side) so reliably
control our physical actions, and how do the sensations picked up from
physical sensors (retinas, nerve endings) so reliably make their way into
our mind?  If there is a separation between the mental and physical worlds,
there must be reliable rules that govern any interaction between the mind
and the physical world, and the interaction must be two way.  How then, can
they rightly be called two separate worlds?

Regardless of who is making the mistake, above you seem to agree with
my premise that there are real natural phenomenon.

This is an interesting way of looking at things: that the capabilities of
natural phenomenon change as it develops more and more complex states of
being.  However, I think the potentiality for those capabilities was there
from the beginning, and the determination of whether or not such
potentialities existed in the primordial universe could in theory, have
been made by a sufficiently great intelligence that had a proper
understanding of the natural phenomenon.

What did the universe have to do to set the speed of light?

If not laws, then what?

You might need sense to notice the pattern, but patterns exist that we are
unaware of.  If this were not the case, there would be no room for

I'm not opposed to the idea that possibility or experience could in some
sense be more fundamental, but I don't see how this could change the fact
that we observe matter and energy to always follow certain rules, and find
evidence (when we look at stars and galaxies very far away) that these laws
have been in effect long before life on Earth arose.

So you deny there are any natural laws?  This might explain why some people
find it difficult to carry on conversations with you.

So then natural laws come from nature.  Earlier you said natural laws don't

That's fine.  The question is whether you believe that a sentient being, in
theory, is capable of developing such a formal system and in it, a
codification of the natural laws that govern the behavior of brains and

If in every experiment we conduct, we find an accordance between physical
experiments and predictions made by our acquired understanding of the
natural laws then this would hold true to an emulation of a human brain.
 If there were any difference between reality and the the physical
emulation, it would indicate to us that our model was incomplete.

You seem to believe that no matter what progress is made, we can never
understand all the natural laws that govern brains and bodies.

Precision and accuracy are exactly what is needed to emulate the subatomic
particles that compose our "ambiguous and volatile" brains.

Remember, I am not talking about awareness above, only behavior.  Do you
think any machine could approximate Einstein's behavior to such a degree
that his friends, family, and colleagues could not tell the difference?
