By the time you read this, I may already be dead.
I say that in the sense that statistically any of us could be dead by the time you read this. Though if you are reading it you are yourself not dead, obviously, but you could be dead by the time the next person reads it. We're all floating above the black, snarling pit of death on soap bubbles.
I live in a world where nobody believes in ghosts but everybody believes in the soul. Go to a funeral and it's perfectly acceptable--even expected--to say something like, "I know your father is in a better place, looking down on us." But if you say, "I see your father standing there in the corner, and you should know the separation from his physical body has already driven him insane," then they ask you to leave.
Why believe one statement and not the other? They're both equally strange. What is the soul but a ghost that happens to be possessing a pile of spoiling meat, walking the earth until the meat rots around it and the ghost escapes? Probably 90% of the earth believes that.
Look your best friend in the eye, what are you seeing? According to all of the major religions, it's a ghost. A spirit, peering out at you from two round, squishy orbs. When your friend says hello, that's a spirit, animating a flapping, wet slab of meat to speak to you from the beyond.
Either that is true or it is not. I can't make you believe one thing or another. But if you do believe in souls, and gods and devils, then you have to accept another thing: when you look at them, they look back. A priest once told me that reading about Satan isn't like reading about rocks or plants. If he's real, and can do everything they say, then he knows he's being read about. He peers back at you through the pages.
