Good writing begins with good research. Joe, I recommend you do some investigating into North Sentinel Island, pretty much the only place on Earth where the sort of thing you're talking about has happened. It might benefit you to learn about how this sort of thing has played out in the real world.

Diver Dan, the Indonesians were already being “loaned” wives by the nw coastal tribes.
I’m presuming that explains part of the physical differences seen in these areas.

SteeleRedux, just out of interest, what parts of culture are you reviving?
I’m always pleased that people take an interest in preserving local languages but that’s a very small part of the overall culture.

Dear Steele,

Thank You for your kind words.

I wasn't sure what sort of statement Joe (Loudmouth)
was trying to make with his novel. However, it intrigued me
enough to learn more and therefore I definitely want him
to persevere.

His story appears to have all the elements to enthral us -
great characters (Condorcet, Beccaria, et al), humour
(Monsieur Antoine), and possibly a firm moral couched in
entertaining surroundings that will hit home gently.

Joe's reference to "the noble savage" aroused my interest.
Shades of Desmond Morris and "The Naked Ape."

I look forward to what happens next.

Sometimes when we venture on a particular journey (as Joe
is attempting to do) we get more than we initially expected.
And the experience is its own reward.

Don't you just lurve the affair between Foxy and SteeleRedux! Thanking each other. Complimenting each other. For Foxy, it used to be A.J. Philips, another extreme Left misanthrope. A.J is out, SR is in. It's like watching one of those 'reality' TV shows.

Dear ttbn,

Don't be jealous.

I'm sure that there's people on this forum that
like you as well. (smile).
