Defined *that* weakly the only thing required of a meme [long form,
self-replicating information pattern where the locus of action is a
brain/mind] is that there be a previous instance that is "copied,"
imitated, whatever. It even matches my distinction that a never
communicated idea falls short of being a meme, although any such idea is a
*potential* meme. ("Self" doesn't add much to "replicating" in the weak causal requirement, "there was an earlier one.")
I can certainly go along with that.
It is analogous to the way viruses replicate by hijacking the DNA/RNA
replication machinery of a cell where they don't have a hand in creating
the replication machinery (or certainly not all of it).
Prions (mad cow, BSE, CJD, variant CJD) are another class of
"self-replicating" in this sense. They are tightly folded proteins that cause a particular nerve cell protein in contact with a prion to fold into the same tightly folded form. They are, of course, parasites requiring the normal protein as "feed stock." There is no complete causal loop to make more normal protein since replicating prions kill the organism by destroying its brain. [Incidentally, prion cases arise spontaneously in brains on rare occasions. So do new memes. :-) ]
Memes infesting humans that induce suicide, or celibacy, or whacking off
gonads are in this class of deadly parasitic replicators (or
self-replicators in this weak sense). They thrive--to the limited extent
they do--by hijacking the mental machinery built by genes to be receptive
to the large class of rock-chipping, pot making memes, i.e., the survival
enhancing memes that enabled humans to become the most successful animal
for our size in the history of the planet.
There *is* a strong (though long and complicated) causal loop for survival
enhancing memes which includes selecting genes that build brains/minds
better able to propagate the survival enhancing memes. (Just as there is a
short causal loop for genes that make DNA replication machinery and a much
longer causal loop for animal genes enhancing brain traits that lead to
behaviors that improve reproductive success.)
It seems to be a law of nature that any success gets parasitized. Viruses
do it to cells, computers have them, and some memes parasitize human minds.
It has been my opinion for many years that investigating the spectrum from
deadly self-replicating information parasites to essential memes like
agriculture is where the most "survival enhancing" progress in memetics
could be made.
Perhaps in discussing memes we need a little ASCII graphic to denote where
we think a particular meme lies on this spectrum from deadly parasite (Jim
Jones), neutral fad (songs?), and essential symbiote (agriculture).

Thank you for inducing me clear up the way I present this material.
