What is meant by “the supernatural”? Supposedly, a realm that transcends nature.
What is nature?
Nature is existence—the sum of that which is.
It is usually called “nature” when we think of it as a system of interconnected, interacting entities governed by law.
So “nature” really means the universe of entities acting and interacting in accordance with their identities.
What, then, is “super-nature”?
Something beyond the universe, beyond entities, beyond identity.
It would have to be: a form of existence beyond existence—a kind of entity beyond anything man knows about entities—a something which
contradicts everything man knows about the identity of that which is. In short, a contradiction of every metaphysical essential.
To assert the existence of another Nature is to create what is unnecessary.
Karl Popper (developor of Falsifiability in Science) explained Occam's Razor in these terms:
a simple theory applies to more cases than a more complex one, and is thus more easily falsifiable
The Supernatural can mean anything to anybody, cannot be tested nor falsified and creates unnecessary complexity in place of verifiable simplicty.
So then, WHY DO YOU BELIEVE IN THE SUPERNATURAL? The Supernatural can only be accessed by "faith".
The alleged short-cut to knowledge, which is faith, is only a short-circuit destroying the mind.
