Once I learned the power of memetics I started imagining weird stuff. Picture this: I saw a movie when I was a kid in 1953—Invaders from Mars
. One of the great early sci-fi movies, along with The Thing
The evil monster was a head with numerous tentacles inside a fishbowl (you can see it at the end of the trailer.) When it pointed a tentacle at a freaky-looking slave that looked like a walking potato sack, it did the head's bidding. If you never saw this movie you're in for a treat.
That's the way it is with religious meme complexes. The invading brain tumor points to an idea in the brain, and the membot obeys: get a tatoo of a cross, wear rosary beads around your neck, kiss the floor and stick your ass up in the air, tell everyone you know about "The Word." What else could convince a person to join an order, climb up a mountain to a little shack, and stay up for the rest of life, praying and reading the Bible?
Or how about blowing oneself up for instant martyrdom?
When the memeplex points its tentacle, obey? God will bless you.
