Foucault-L mail-list

Hello,

I'm looking for information about how discourses replicate.

I think memetic theory provides some insight into the reproduction of 
discourses. I would like to know if there is some sources where I can 
look into this further. 

Can memes be interpreted in the categories used in Archeology of 
knowledge? Is a meme a 'statement' or it is a 'discourse'?

I have a feeling that there might be some use into looking at 
discourses in terms of fitness and I just wonder if anyone knows where 
I can begin looking to see if this feeling holds any water.

Thank you in advance,
Sam
