On the neurobiological claims, Dr. Kevin Spencer had inmediately 
remarked on Tue, 2 Apr 1996 03:03:14 -0300:

On which Zaman answered the next day, Wed, 3 Apr 1996 13:46:22 -0300

The same day Tue, 2 Apr 1996 16:30:59 -0300, Dr. Paul Bush 
<paul at>	<paul at> signaled, regarding
previous postings of the divinity student:

It was in this situation that I (Gabriel David Noel

(Per omnia saecula saeculorum, I ought to have added.) I am not
interested in struggling with the shamanic proteism of this netter.
The short time to ordering all the messages I have at hand was
perhaps useful for newcomers or occasional visitors to the
forum. But IMHO we all, those who were interested in this thread,
shall harvest the best fruit if concentrating on the evaluation of what
possibilities had Verzeano's work to fulfill the role anticipated by
Zaman.  If so, even against himself Zaman would have provided a
service to the neuroscience community. If not, I feel it shall be
yet instructive to our work.
