There’s a point to being a skeptic, and learning how to be a good one. You can’t just pick what you’re skeptical about. I don’t understand how someone can claim to see and feel an inordinate amount of ghosts, but then argue the validity of them to what her friends see, or what she sees on TV.
Anyway, the point is to learn how to discern the truth. Not something that feels like truth, but the truth even when it blows. Being a skeptic means that everything you encounter has to fit in with all of the substantiated evidence we hold. And unfortunately for ghosts, there’s an insurmountable amount of evidence against. Not only directly, as in scientists testing psychics and waving around myriad detectors in “haunted houses”, but also indirectly as in everything we know, and put into practice about the laws of physics says it’s practically impossible.
Yes, I understand that science changes its own rules over time on a regular basis, but they’re more of a refining than a complete paradigm shift, as finding out there’s such thing as a “spectral realm” would be. If it exists, how can you reconcile it with our physics as they stand now? How are these ghosts, who aren’t detectable by any sort of instruments we have, and who can pass through any sort of matter, able to interact with people and see our light and watch our movies? How are they able to cling to the earth which is hurtling around the sun as the sun is hurtling through the milky way, and as the milky way is – well, you get the idea. It opens up a whole can of worms.
Also, if there is a spectral realm where these ghosts reside, what is this plane of existence like? Does it mean there is a God, after all? And who is he? Also, why don’t we see alien ghosts from other worlds? Blah blah blah…
In my experience with people I’ve encountered with people who assertively believe this stuff (my youngest sister is one of them), they are of a certain personality. They are heavily credulous, lack even the most basics of healthy skepticism, no good scientific knowledge, are attention grabbing, and being able to “see” these things makes them feel special.
In the end, not being a skeptic deprives you of living a life that is able to take in the true mysteries of the universe, to recognize what those are, appreciate them, and see our place in the cosmos. It keeps you gullible and open to cons. It may be fun to believe in this stuff, but it’s a deluded game of pretend, a distraction at the least and damaging to your ability to discern what’s real and what’s not, at the worst.
