Memes have becomes memes.
When i first read Darrel Ray's God Virus I was confused as to whether he was positing a real phenomenon or was drawing an analogy. And when i hear or read others expand on or elaborate about some meme or other i am similarly unsure as to what is meant.
So for anybody who is a proponent of memes are you making a metaphor or do you mean that there is some observable and measurable phenomenon. Is there a change at the molecular level once a person has been memed into a belief?
