Is Science Based on Faith?


When someone is trying to prove a point (usually to do with the physical world), they will often refer to science by saying something along the lines of “it’s been scientifically proven that X is true.” After this is said, supposedly the case is settled unless there is some sort of evidence to the contrary. This points to the fact that today in current culture science has been venerated, and for clear reasons too – technological advancements (phones, space rockets, computers) – biological advancements (health care, genetics), the list could go on and on.

Great as this may be (and I am a huge fan of science), my one fear is that this sort of progress has led to a very biased approach towards how we view science. Many people have lifted science above all other fields of discipline such as, history, philosophy, art, politics and so on. The most extreme version of this bias comes in the form of scientism – the view that science is the only way to know truth – now this worldview is easily defeated (the statement itself cannot be scientifically tested and so if it is true…it is false), however, that isn’t my main focus here. I really want to focus on the concept of science and faith.

For clarification, when I say faith, I don’t mean it in the sense of religious faith in a creator (there are at least four different definitions of the word faith), I mean faith in the sense of warranted faith, the type of faith that everybody on earth exhibits on a daily basis whether they are religious or not in order to get through life. For example, when you go to drink water from the tap or a bottle, you do not conduct science experiment upon science experiment to determine if the water is clean to drink. When you are sleeping at night, you do not barricade yourself in your room for fear that a family member or friend will walk in and suddenly pull a knife on you in order to do you damage. The list runs deep but when we really take time to view how we live life, we realise that we really do exhibit a lot of faith, and that is what gets us through. The main question again I want to address is this: Is science based on faith?

Now before we get into this, we need to define the word faith. The English Oxford Living Dictionary defines faith as:

Complete trust or confidence in someone or something 

In this sense, we don’t necessarily have to include anything specifically religious at this point, we are just talking about having confidence and trust in something, and anybody is capable of that.

So, is science based on faith? Well on the surface, it seems that the answer is a clear NO, of course it isn’t. Science works via observation, testing, repeating and confirming results, it is in the business of strictly empirical findings. This would seem to be true, and it is! However, the question that I’m asking is not about what science does, but rather what it is based on…or in other words, what makes science possible? I will just focus on one topic below in order to try and help answer the question…mathematics (there are many more paths we could go down).

Mathematics, science and faith?

Science, especially the discipline of physics is based upon mathematics. Mathematics underpins science and seems to uphold it (in a sense). The problem here is that, mathematics – as any scientists will tell you – is law like, so much so that it is essentially refer to as “laws of mathematics”. In order for scientists to be able to land people on the moon, and to be able to send satellites into orbit around the world they have to utilise these laws of mathematics. The huge underlying questions however are: what are the laws of mathematics? Where did they come from? And why are they so consistent? Notice that scientists didn’t create and do no not uphold these laws of mathematics. Einstein knew this very well when he made the statement saying: “How is it possible that mathematics, a product of human thought that is independent of experience, fits so excellently the objects of physical reality?”[1]

The problem is that science is supposed to works empirically, however, the laws of mathematics are immaterial. E=MC2 is not something physical you can touch, it is an immaterial mathematical equation which helps us to understand the nature of mass and energy. Hopefully you are starting to see the big picture here.

Fundamentally, there is a major disconnect between ‘doing science’, and ‘knowing why science works’. The ‘knowing why science works’ part is something that is believed primarily by faith when it comes to truths such as mathematical laws. In fact, this topic cuts so deeply into the world of science that it caused Nobel Prize winning mathematician Eugene Wigner to write an entire paper entitled The unreasonable effectiveness of mathematics in the natural sciences. The last quote at the end of the paper is probably one of the most striking, and it puts a finger on Wingers central thoughts on the whole topic. Winger says that:

The miracle of the appropriateness of the language of mathematics for the formulation of the laws of physics is a wonderful gift which we neither understand nor deserve. We should be grateful for it and hope that it will remain valid in future research and that it will extend, for better or for worse, to our pleasure, even though perhaps also to our bafflement, to wide branches of learning.[2]

This to me is a bit like a statement of faith from Wigner, and this is not a bad thing! It is just simply an admittance that science does not contain all the answers, and furthermore, it is an admittance that science cannot even fundamentally account for why it works in the first place.


Science and Religion

With this now is mind, I think it is easier to show that the straight line that people tend to draw between science as being “empirical truth” and religion as being “based on pure faith” in not as easily marked as first thought. A few point to consider are that:

  • Faith is a concept that applies to everybody whether religious or not.
  • Science is based upon faith on mathematical laws (and we could extend this to faith in gravity, energy, and light as well since nobody in the world knows what any those things fundamentally are)
  • There are at least four definitions of the word faith (Warranted, blind, evidence based, irrational,) and so we must know which definition we are talking about when we speak about the word
  • Scientists have a fundamental faith in certain unexplainable phenomena just like religious people do. God’s existence cannot be explained by humans, but neither can the laws of mathematics, or gravity, or energy, both fields exhibit very large degree of trust…faith!
