Question from Rory:
When confronted by the issue of the existence of ghosts or spirits by a religious person I find myself stumped to find a scientific explanation to respond with.
Obviously many supposed sightings of ‘ghosts’ have been misunderstandings, camera trickery or an exaggerated memory.
Much like the stories of religion and the image of god, our perception of what a ghost is is entirely manmade; usually the image of a transparent human figure.
But suppose someone really did see something paranormal, irrefutably standing in front of them, maybe a human figure or some other unexplainable entity. Are there any scientific theories to explain these things? Is it possible to see reflections of the past, for example?
I should point out, I do not believe in the existence of ghosts and have never seen anything that I could ever perceive to be anything paranormal.
I am an atheist and don’t believe in much more than what we see and can be proven.
Neither do I believe in ghosts. I simply feel that when combatting an argument against someone who claims to have seen a ghost, the argument of the sighting potentially being anything and simply a misunderstanding comes across as vague and weak (although almost certainly true).
IF someone really did see a ghost, spirit or other supernatural entity, and could prove beyond reasonable doubt that they did (have fun imagining how), then naturalistic views of the universe would be challenged. That’s a big if. Significantly, this has not happened (or even been convincingly faked) in centuries of investigations and claimed sightings.
Thinking sideways for a moment, if the basketball at the next NBA finals were to suddenly fall upwards and get stuck under the scoreboard, the theory of gravity would be challenged and science would have a lot of catching up to do. That does not mean it’s at all likely to actually happen.
That said, since science is permanently in the business of correcting itself when new information and evidence come to light, it’s probably quite likely that phenomena will be observed which at first do not seem natural, but will ultimately be furnished with a natural explanation which is then confirmed by experiment.
James Randi has a word to describe such phenomena: perinormal rather than paranormal. Peri, as in “periphery”, implies that such things are right on the edges of human knowledge waiting to be discovered. When Randi was running his Million Dollar Challenge to test self-proclaimed psychics, it was his faint hope that a candidate would pass the test and demonstrate a real perinormal ability, and that the discovery of its mechanism would be well worth the prize money.
For the moment, however, there are no unambiguously demonstrated perinormal phenomena to consider, let alone genuinely paranormal. So we wait, and we investigate claims. The burden of proof is on those making the claims. Responses to unsubstantiated claims are necessarily vague, since an unsubstantiated claim tends to be devoid of useful, verifiable details. That doesn’t make the responses weak relative to the claims, it simply makes them appropriate.
One other point I should make is that if religious people are making claims of ghosts in order to support their religions, it’s worth asking them and yourself whether what they describe actually links exclusively to one religion. Otherwise they may in fact be describing events which, if true, suggest that they’re worshipping the wrong god or gods.
