I think Bateson's definition of information is very convenient (and more
appropriate in the context of memetics than Shannon's - which deals
basically with the 'form' of the message): "Information is a difference
which makes a difference". A nucleotide strand in a test tube is not
information, like an unread book is not information, both have the potential
for making a difference, though.
There are two ways of studying memes. One is asking sociological and
psychological questions: why is an idea successful, why do humans preferably
believe one idea over another. Actually the kind of questions which interest
me most because of the possibly ethical and social impact (we could become
'better' beings by better understanding what is going on in our minds and
The second approach is trying to find analogies between biology and culture.
My conclusion is that written, electronic, printed, ... TEXTS are best
comparable to genes, and thus are the real memes (when thinking in
(To make sure: this has nothing to do with Gatherer's conclusions concerning
Windsor knots and pottery.)
Texts have unlimited informational content (cfr. Maynard Smith & Eos
Szathmary: The major transitions in evolution), texts are recombinable,
texts are copyable (replicable), texts have high copy fidelity, texts exist
independent of ongoing metabolic activities, texts are material stuff like
genes are, texts are differences which have the potential of making a
difference, like genes have, etc.... This is of course a completely
different story of memetics/genetics and maybe only of secondary importance
in the social context.
