Robert,
You accuse Nick of talking about "the brain", when he was
talking about "the mind".
The most basic tenant of behaviorism is that
all questions about the mind are ultimately a question about behavior.
Thus,
while some behaviorists deny the existence of mental things, that is
not a
necessary part of behaviorism. On the other hand, the behaviorist must
deny
that the mind is made up any special substance, and they must deny that
the
mental things are somehow inside the person (hence the comparison with
soul,
auras, etc.). If the behaviorist does not deny tout court that mental
things
happen, what is he to do? One option is to claim that mental things are
behavioral things, analyzed at some higher level of analysis, just as
biological things are chemical things analyzed at some higher level of
analysis. So, to answer your question: There IS a brain, and the brain
does all
sorts of things, but it does not do mental things. Mental things
happen, but
they do not happen "in the brain". As Skinner would put it, the
question is:
What DOES go on in the skull, and what is an intelligible way to talk
about it?
The obvious answer is that the only things going on in the skull are
physiological.
For example, if one asks why someone chose to go left
instead of right at a stop sign, one might get an answer in terms of
the brain:
"He turned left because his frontal cortex activated in such and such a
way."
However, that is no answer at all, because the firing of those neurons
is a
component part of the turning left! Ultimately, the explanation for the
choice
must reference conditions in our protagonists past that built him into
the type
of person who would turn left under the current conditions. In doing
so, our
explanation will necessarily give the conditions that lead to a person
whose
brain activates in such and such a way under the conditions in
question.
Put another way: To say that he chose to turn left because a part of
his brain chose to turn left misses the point. It anthromorphizes your
innards
in a weird way, suggests homunculi, and introduces all sorts of other
ugly
problems. Further, it takes the quite tractable problem of
understanding the
origins of behavior and transforms it into the still intractable
problem of
understanding the origins of organization in the nervous system.
Neuroscience
is a great field of study, and it is thriving. Thus, people hold out
hope that
one day we will know enough about nerve growth, etc., that the origin
of
neuronal organization will become tractable. One day they will, but
when that
day comes it will not tell us much about behavior that we didn't
already know,
hence they won't tell us much about the mind we didn't already know.
Or
at least, so sayith some behaviorists,
Eric

Let me try this on(e)... it's because the brain is the physical
structure within which our thinking processes occur and collectively
those processes we call the 'mind'. I don't see a way to say the same
thing or anything remotely parallel, about soul, aura, the Great
Unknown and such. Is there an argument to say that the brain, or the
thinking processes don't exist in the same way we can argue that the
others don't (or might not)?
Thanks

How is banging on about mind any
different from banging on about soul, or aura, or the Great Unknown?
