You did know I would end up here, right?
A Zombie is a corpse said to be revived by witchcraft, especially in certain African and Caribbean religions. The Magic Island, a sensationalized account of a narrator who encounters voodoo cults in Haiti and their resurrected thralls, introduced the concept of the voodoo zombie into western culture. Since then the zombie has evolved into a mindless flesh/brain eating re-animated corpse, popularized by movies like Dawn of the Dead, shows like The Walking Dead, games like Left for Dead, and books like How to Survive the Zombie Apocalypse by Max Brooks.
Excerpt from Hogfather by Terry Pratchett
“All right," said Susan. "I'm not stupid. You're saying humans need... fantasies to make life bearable."
REALLY? AS IF IT WAS SOME KIND OF PINK PILL? NO. HUMANS NEED FANTASY TO BE HUMAN. TO BE THE PLACE WHERE THE FALLING ANGEL MEETS THE RISING APE.
"Tooth fairies? Hogfathers? Little—"
YES. AS PRACTICE. YOU HAVE TO START OUT LEARNING TO BELIEVE THE LITTLE LIES.
"So we can believe the big ones?"
YES. JUSTICE. MERCY. DUTY. THAT SORT OF THING.
"They're not the same at all!"
YOU THINK SO? THEN TAKE THE UNIVERSE AND GRIND IT DOWN TO THE FINEST POWDER AND SIEVE IT THROUGH THE FINEST SIEVE AND THEN SHOW ME ONE ATOM OF JUSTICE, ONE MOLECULE OF MERCY. AND YET—Death waved a hand. AND YET YOU ACT AS IF THERE IS SOME IDEAL ORDER IN THE WORLD, AS IF THERE IS SOME...SOME RIGHTNESS IN THE UNIVERSE BY WHICH IT MAY BE JUDGED.
"Yes, but people have got to believe that, or what's the point—"
MY POINT EXACTLY.”
