Perhaps we should define what 'Bloch's paradox' actually *is*. I thought
he was saying that you cannot study an extinct meme without 'resurrecting' it.
Now, I repeat what I said previously - you cannot study an extinct meme *at all*
if it is truly extinct - because it is lost forever. Hence, there is a paradox,
but a slightly different one.
I would say that the only way to really study an extinct meme is to infer that
there probably was a meme, and deduce what its nature was. (e.g. a missing
word, a silent film of children singing a missing song).

This would be extinction 'in the wild', with a few limited copies of the meme
held in isolation. However, you have to start with a non-extinct meme and
'preserve it' while it goes extinct elsewhere - this does not allow you to
study already-extinct memes.

if you can "observe directly" a meme THEN IT IS NOT EXTINCT!

This is more interesting. Memes describing behaviours or 'what it's like',
(for example: what it's like to see the colour red, or to smell coffee) seem
to be tricky things. Certainly, they seem to be lost when using the written
word. I can't write down a copy of my belief in Zeus (should I have one).
I can't write down exactly what it's like for me when I see the colour red.
Perhaps music is a better form of transmittal for these memes, but even so...
What I'm getting at, is that your belief in a deity is a personal thing.
I'm not sure it gets 'transmitted', more 'recreated' with help from others.
So these memes seem to only exist within humans, not in any form of written
storage. And there seems to be no *direct* transmittal (I can't give you a
copy of my faith in Zeus). So can such 'behavioural memes' become extinct or
