Many believers think that believing in a god or a divine force is the same as believing in a scientific theory.
Obviously, this is a fallacy - a clever but misleading play on words. Belief in a scientific theory has absolutely nothing to do with belief in a deity. In fact, even using the word “belief” in a scientific context is inaccurate.
I suspect this is a way for some believers to logically justify their faith - by playing with language and framing things in a way that equates science with belief.
On the opposite extreme, equally unfounded, are those who claim they can prove the existence of a god or the supernatural.
Personally, I find these attempts - both to equate faith with science and to “prove” faith - unnecessary. Believers should embrace the reality that their faith has nothing to do with science, that it isn’t proven, and that it doesn’t need to be.
After all, it’s easy to “believe” when you have proof. At that point, it’s no longer belief - you simply know. The real challenge is to have faith without guarantees or evidence.
And perhaps that’s exactly what believers should take pride in.
Notes
1. In science, the word "belief" is rarely suitable. We prefer hypothesis, model, "we propose".
2. We all know that science is not absolute. Scepticism is built-in. There is no absolute scientific truth. All scientific theories are evolving. Some theories are proven simply wrong. Some evolve into better theories.
The concept of falsifiability is worth mentioning. Religious or supernatural belief is not falsifiable.
3. Science produces provisional, evidence-based truths.
Some theories are extremely stable. Some not.
4. So here's the interesting question, it's the meta: what is truth in science?
The theory that I particularly love is utilitarian/pragmatic. It is very suitable in engineering, and in social sciences (management, sociology), but also applicable in all sciences.
"A theory is true if it works."
5. Mathematics is probably the weirdest science, btw. It is at the same time very practical, and also very abstract, both in language and concepts. It is full of paradoxes - it even negates itself (it proves that it cannot be complete, it is limited by design - Gödel's incompleteness theorems).
And mathematics also works: we use it exceptionally well to cook food, to build houses, generate fake photos, discuss on Facebook, and to put people on the moon.
7. So no, we don't "believe" in science, or scientific theories. We build it, we discover it, we invent it, we demonstrate and prove it, we challenge and evolve it, we apply it in practice.
8. No matter what theory of science we use, the idea that we "believe" in a scientific theory is, in principle, inappropriate.
