<<In a recent e-mail convesarion with Mario Vaneechoutte he pointed out to
that since memes don't self-replicate although they do evolve, they do not undergo natural selection in a similar manner to biological life.>>
Memes do self-replicate by definition. Memeplexes [Blackmore] and Viruses of the Mind [Brodie] also self-replicate. Saying they self-replicate is simply invoking the model known as the intentional stance [Dennett]. How "true" it is depends on the accuracy of the predictions made.
A lot of the confusion in memetics stems from not realizing there are more than one kind of cultural replicator.
