The extinct meme can be studied indirectly by the evidence it left, much
as even the Big Bang can be studied.

Actually, the whole notion of ever saying that two entities are in some
way "the same" is a tricky matter that is often taken for granted in
science and elsewhere. It is the axiom of abstraction, (also called the
axiom of comprehension), and we can only say that two entities are "the
same" with respect to an abstraction. But then we try to make our
abstraction system have a good correspondence to external reality, and
biological evolution has favored brains capable of this to some extent.
But here we have abstractions about the mental or neural information of
animals,--in this case humans. Even in an ancient Demeterism no two
people had EXACTLY the same neural information, but only the same with
respect to some abstraction. Hence in Demeterism retransmission, the
resultant new host's neural was never exactly the same as anything in
her instructor's nervous systems. But we are especially tempted to think
of them as EXACTLY the same because of their close proximity and
intimate communication. But what if communication goes from an ancient
scribe to a slightly less ancient reader several generations later? Or
several millennia later? Surely the "copying fidelity" of such
transmission events will be lower than for the typical mother to
daughter communication. Whether you count the 20th century believer as
having "the same" belief depends on how strictly you define Demeterism.
Embedded in this is how well any modern abstraction system (including
the definition of Demeterism) represents a real ancient phenomenon, for
only by an abstraction that corresponds well to reality can you be
CORRECT in saying that someone's ancient belief was "the same" as
someone else's modern one.

Well, to examine ANYONE else's belief system requires us to become host
to at least PART of that person's neural information, even if merely in
a representational way. But with a well-defined "sameness" criterion,
this does not generally cause a new instantiation of the meme under
study, and hence neither an incrementation of that meme's host
population. If it did, then the question of whether the other person
lives today next door or last millennium next continent does not matter.
When I study the beliefs of a Muslim next door, I do not thereby
increment the host population of Islam by 1. By the same token, if I
indirectly study the ancient Demeterist, I do not thereby increment the
host population of Demeterism by 1--and Demeterism remains extinct even
under retrospective scrutiny. It's a matter of being careful (and not
getting confused) about what you count as "sameness."
