Sirona... that definition of love could be tested via questionaires.
Obviously to say we know it all is an incorrect statement.
But the very changable nature of paranormal experiences according to enculturation is illuminating.
People see UFOs in the sky . People used to see angels, armies and mythological beasts in the sky.
Studies of NDEs indicate the nature of the NDE is shaped by a person's feeling of self-worth.
Christian's have different paranormal experiences to Animists.
This is clear evidence they happen due to internal factors rather than external entities.
So, what we have seems to be internal factors. Given that, is it real?
Well, if you believe we were created in anyway the following isn't of much interest to you.
Evolution hates waste. If we have something, it has to be efficient, or else it wouldn't be there. Natural selection produces organisms with the features they need to survive. If an animal needs to run, it will have legs; they are not 'inheritable' in the sense of blue eyes, they are basic equipment, albeit that works in differing efficientcies in different people.
The fact that not everyone has paranormal powers indicates they are not of a survival benefit, or they just don't exist.
The only exceptions to this explanation are;
1/ Paranormal powers are selected for by some other process other than natural selection; sexual selction, e.g.
2/ Paranormal powers have a survival benefit, but are a comparatively new development and thus have not penetrated the genome to the extent other survival benefits have.
So, in short I advance the theory that unless paranormal powers can be shown to have some non-survival benefit, or are a new thing in human evolution, they just don't exist, as their is no explaination for them coming about, and natural selection can't develop things for fun, it can only develop things due to selection pressure.
