I'll have to reply to your comments in three individual posts, as I
need to include your own text, and I can't get my email to merge your
three messges into one for easy quotation.

Yes, phylogeny! Or maybe we should say phyloMeny...? Armed with my
tatty library copy of Murdock's Ethnographic Atlas, and a freeware copy
of Phylip, I have been struggling with this one for a while.
Initially, I had decided that the easiest societies to analyse would be
the simplest, so I spent much of last summer rooting around the data
on archaeological sites from the English Palaeolithic. I tried to
classify societies according to whether they had a certain stone tool
culture or not, on the rationale that tool design was more likely to
spread horizontally in a Rogerian diffusion model than to be reinvented
repeatedly. However, I soon ran into the problem that it is never
possible to say for certain that a particular group of cave people
_didn't_ have a certain tool - all we can say is that we haven't yet
found an example of tool type x for population y. Since my phylomenies
(ahem!) could change quite markedly by the addition of one tool type or
another to a particular society, I had to concede that my cultural
trees are probably not going to tell us much about the evolution of
Palaeolithic society in England.

For this reason, I moved on to Murdock's Ethnographic Atlas, which at
least has complete data sets for its population groups. However, it
does make the tree construction a little more complicated. I was also
quite alarmed to see that Cavalli-Sforza had written the following
(Guglielmino et al 1995, p.7585)

'....It [ie. Cavalli-Sforza' method] does not try to reconstruct the
history of the origins of innovations in the tree of descent; this is
sometimes a difficult proposition, given that the spread of a group in
a new area rarely can be represented by a tree branching without
reciprocal connections.'

which does make me wonder if I am perhaps barking up the wrong tree on
this one?

> Can't we study the structural epidemiology of belief, as objectified in

I would say yes, but only if the symbol is something we can objectively
identify and if possible quantify. Eg. the number of prayer books
manufactured in Victorian England that have silver crosses on the front
of them - since that tendency was noted by Trollope (I'm stuggling to
remember which novel, I think it was the first one in the Barchester
Chronicles but the title escapes me - The Warden, that's it!) to be a
reflection of the spread of Anglo-Catholicism.

and Paul countered with:

Well, in that case you have to perhaps explain to me what Geertz means
when he says: (Geertz 1973, quoted by Durham 1991, p.32)

'... the whole point of the semiotic approach to culture is to aid us
in gaining access to the conceptual world in which our subjects live.'

Gaining access to the conceptual world in which our subjects live?
Sounds like understanding from the inside to me. And is it really 'the
whole point' as Geertz says?

Of course, we both agree it isn't the whole point, so I'm being
rhetorical, but I mention it just to point up the differences of
emphasis between the inside-out and outside-in approaches.

> they are interested not in what you have but what you pass on,

Good. I am in absolute agreement. Memes are not what we have but what
we transmit. (I'll be pursuing Aaron further on this one in
another post).

I object to none of this, as long as it _can_ be measured. We should
be clear however, that we are not measuring internal mnemons.

Yes, I will start a new thread on that one, in a week or so perhaps.
