Ghosts seem unlikely. If it’s possible for something as complex as intelligence to be manifested incorporeally, you’d think that natural selection would have done more with the principle by now.
Even if ghosts are just some sort of freaked-out time hiccup or something, there really ought to be more evidence of them. They are observable phenomena after all, and people find them really interesting. It seems like such a huge pile of eyewitness information should be a real aid toward understanding and predicting the phenomenon.
It worked that way for comets. For thousands of years comets were these incomprehensible random messages from the gods. Then somebody got the idea to examine them systematically, and lo and behold they’re eminently predictable. The guy on PBS will even tell you when to go outside and look for one.
Yet ghosts are just the opposite-- their manifestations are most impressive when they are at their least verifiable. The most impressive ghost stories are those that happened to the friend of a friend, or in decades-old folkloric accounts. The Headless Baron walks the battlements every full moon, leaving a trail of steaming blood. The ghost of Illinois Central 42 appears, spectral whistle a-screaming, along the very stretch of track where it derailed 20 years ago this very day.
Look any closer, and it all starts to come apart. Okay, it turns out that ghosts can be photographed! That’s something! Except the photos have always looked suspiciously identical to ordinary double exposure effects. I’m pretty sure that ghosts were not generally described as semi-transparent or glowing prior to their representation in stage illusion and spirit photography.
Nowadays everybody has cameras built into their pocket phones, and yet somehow modern paranormal researchers are forced to chase after minute variations in temperature and imperceptible magnetic fields in their search for evidence. Nobody ever told a ghost story featuring a scary magnetic field! Where’s the Headless Baron? Where’s the blood?
I think that ghosts are an interpretation of a particular category of human experience, and as such will continue to occur as long as humans have those experiences. They’re sort of analogous to the fovea of the eye, in a way. Most people assume that they have a seamless and uninterrupted field of vision. Is this really a mischaracterization of one’s perception? It’s easily demonstrated that this is not objectively true, but only by examining one’s vision carefully.
For thousands of years, nobody realized that every human being has a huge blind spot in their field of vision. And even after this was discovered, people who know about it don’t actually experience it subjectively. We don’t suddenly find ourselves troubled by this missing expanse of visual field on a daily basis.
Similarly, ghosts are a perceptual phenomenon that are probably experienced by everyone. It’s just that the experience itself is not truly objective. “Oh, I thought I saw someone over there in the moonlight for a second,” says the person who does not believe in ghosts; or “I could have sworn I heard someone speaking.” If you’re actively expecting your dead family members to appear, though, it’s a different story: you DID see them, you DID hear them, that’s what you’re going to tell others, and pretty soon everyone knows about the Headless Baron.
I’ve seen this effect in my own family. My mom is surrounded by ghosts. She even has a photo of one, which she can look at and identify easily as the robed spirit of my grandmother. To me it looks suspiciously like an out-of-focus streak of bird poop on a window.
She also saw the ghost of my brother soon after he died. That wasn’t how she first described it, though. At first, very shortly after the funeral, she was startled into a fit of crying by a “shadow” passing by the window. Some weeks later, she was certain that it was my brother who had looked in at her. Later still, she was confidently able to describe details like his expression, his clothing, and the fact that he was wearing his favorite hat.
I don’t think this is very unusual. Ghosts are supposed to be the spirits of the dead. We’re most vulnerable when people we know have died. Strong emotions-- grief, fear, anticipation-- all contribute to reinforce such perceptions.
I don’t even want to start in on the Ouija board. Two people have their hands on the damn thing, and it’s supposed to be a miracle of supernature when it moves. If it spelled out messages without anyone touching it, that would be something else again.
