Science is often criticized for not being able to address the supernatural. It is argued that by adhering to methodological materialism that we automatically preclude supernatural explanations. Some people see this as a weakness of science and argue that this blind spot gives religion some value in explaining our world. I believe that by looking at the concept of the supernatural that one can come to the conclusion that it is not a weakness for science at all. And even that it is largely irrelevant.
For something to be supernatural it must be outside of our world. Angels and demons and God are supernatural because most people see them as inhabiting a sphere of existence separate from our mundane physical reality. In other words, they are beyond nature, hence “super”natural.
I would argue that anything that acts on our world must be a part of our world, or at the very least become part of our world to have any impact. Therefore, anything that is truly supernatural would not be able to affect our world. How can something that is outside of nature have an effect on nature? Anything that can act on or in our world is therefore natural in origin and is therefore a valid target for scientific inquiry. If God exists and can affect our world then God must be natural, or at least have some natural component which means that science is perfectly capable of exploring the nature of God. If God exists and is truly supernatural, and thus beyond science’s grasp, then God cannot have an impact on our world. In which case God may as well not exist for all the difference it makes.
