Why the Word “Supernatural” Is Meaningless

[Periodically, a question comes up asking whether atheists reject the entire idea of “the supernatural” all together or whether it’s just God that we don’t believe in. I can’t speak for all atheists, but as far as I am concerned the entire idea of “supernatural” is a wholly empty and meaningless concept to begin with. Of course, every time this question is asked, I come up with a slightly different way to express my feelings, so this post just captures my various responses.]


The word “supernatural” is wholly meaningless because:
  1. The natural world encompasses everything we can see, feel, hear, taste, measure or in any way detect.
  2. In order for something to truly be “supernatural”, it would necessarily need to not be part of the natural world.
  3. Anything that is not part of the natural world cannot be seen, felt, heard, tasted, measured or in any way detected.
  4. Therefore, regardless of whether anything supernatural exists or not, it is meaningless to talk about it since there is no way to detect it or know anything about it. The moment it becomes detectable in any way, it ceases to become supernatural. 

In my experience, “Supernatural” is just a term that people use to describe proposed things for which there is no proof or good evidence but which we nevertheless think might possibly exist in some sense. Or, perhaps, things that we really wish existed despite all evidence to the contrary. For example:
  • We have no real proof or good evidence that God exists, but we really, really wish He did, so let’s say that God is “supernatural” to explain why we can’t detect any evidence of His existence rather than acknowledging He doesn’t actually exist.
  • We have no real proof or good evidence that ghosts exists, but we really, really wish they did, so let’s say that ghosts are “supernatural” to explain why we can’t detect any evidence of their existence rather than acknowledging they don’t actually exist.
  • We have no real proof or good evidence that psychic powers exists, but we really, really wish they did, so let’s say that psychic powers are “supernatural” to explain why we can’t detect any evidence of their existence rather than acknowledging they don’t actually exist.
  • We have no real proof or good evidence that the human spirit or soul exists apart from human brains, but we really, really wish they did, so let’s say spirits and souls are “supernatural” to explain why we can’t detect any evidence of their existence rather than acknowledging they don’t actually exist.
Rinse and repeat.

Atheists, as a rule, don’t claim to have beliefs or knowledge about ultimate or absolute truths. That’s usually the realm of theists, and atheists generally say they don’t believe those claims.

As a rationalist, however, I strongly believe that “supernatural” is just a term made up to justify a belief in something for which there is no supporting evidence. Sure, there are things in the world that people can’t currently explain. Perhaps there even things that we will never be able to explain (why does seeing a person yawn make us want to yawn as well?). But anything that we can observe or detect or that has any effect whatsoever on the natural world is, as far as I’m concerned, part of the natural world and therefore, by definition, not supernatural.
Or, to put it another way, the supernatural cannot exist because existence itself is a natural state:
  1. Something can be said to exist if it is composed of matter or energy and occupies time and space.
  2. Anything that is composed of matter or energy and occupies time and space is part of the natural world.
  3. Anything “supernatural” would, by definition, not be part of the natural world and would therefore need to not be composed of matter or energy nor occupy time or space.
  4. Therefore, anything supernatural cannot be said to actually exist. Q.E.D.
