Science and Belief

By Eilene Lyon

I once asked a classroom of college biology majors, some of them pre-med, whether they “believe in evolution.” About half raised their hand.

Ha! Trick question.

Science is not about believing. Belief and faith are the realm of religion and spirituality. In fact, you could say that science is the antithesis of belief, because it’s rooted in skepticism. (Though I don’t think I’d want the students who didn’t raise a hand to be my doctor – just sayin’)

This is why science and religion aren’t mutually exclusive. Some scientists are religious. Faith is a very natural human desire.

Science is a methodology. It is analysis of empirical evidence, collecting data, making observations, experimentation. Results need to be replicable and peer-reviewed.

It’s important to understand that science does not prove anything. The scientific method produces hypotheses based on evidence and observation to explain how the world and universe function. Then scientists set about trying to disprove the hypotheses.

Sometimes non-scientists confuse the terms hypothesis and theory, such as when they say that “evolution is just a ‘theory’.”

In science, a theory is the currently accepted understanding of a natural phenomenon that has withstood many, many years of attempts to disprove a hypothesis. If new evidence arises to suggest a revision to the theory, it must undergo the same rigorous testing to become accepted. This has not happened to the theory of evolution since Darwin and Wallace introduced it in 1859.

In other words, theories withstand the tests of time and skepticism.

Science has not proven what gravity is, for example. But it is observable and measurable. Through mathematical formulas, gravity can be understood and be used in a variety of ways.

Once science has a workable theory in place, amazing things can happen. This is why science gives you space travel. Religion does not.

Science gives you artificial hearts and chemotherapy. Religion does not.

Science gives you plastic, electricity, television, and the internet. Religion does not.

Science gives you nuclear bombs. Religion does not. (Thank you, Religion!)

Science deals with the physical realm. Religion, the soul.

Like gravity or solar energy, evolution is an observable phenomenon. It’s the reason new flu vaccines are produced every year. Humans have harnessed evolution through artificial selection (rather than natural selection) to create food, such as corn (I don’t mean the GM variety) and broccoli, for example. Evolution is occurring every moment of every day.

When someone tells you they “don’t believe in” evolution, it’s like they’re closing their eyes tight, sticking their fingers in their ears, and shouting, “La La La La La La La.” They’ll just pretend it doesn’t exist. But it exists regardless.

Darwin and Wallace knew nothing of genes and DNA, which makes the robustness of their theory all that much more impressive.

So, what is the theory of evolution? I’ll explain in my next science post, where I answer the question posed by my friend’s college-age son:

“If humans descended from monkeys, why are there still monkeys?”

Why, thank you for asking!! Stay tuned…

  1. I hear often that atheists have a lot of faith in science. No, but I trust science as it has an incredible success rate, and new technologies and product compositions prove beyond all doubt it is working. Some hypothesis on difficult topics change, but with each change we advance closer to truth and sure knowledge. Just because some are a work in progress, doesn’t make religion a default truth. Great article today. I like!!

    1. Trust is a good word. To me, it’s all about evaluating the evidence to come to an understanding, but always keeping an open mind that knowledge is fluid. There’s never 100% certainty. Rigidity in our thinking doesn’t solve problems.

  2. “They’ll just pretend it doesn’t exist. But it exists regardless.”

    Those two sentences are the crux of why I get exasperated with people. Denial isn’t reality, reality is reality. And avoidance of reality doesn’t help anyone. But then I realize that not everyone wants to help people, themselves included, and that any change for the better, or my accurate understanding, is difficult for certain people to accept. A reality I have to accept, I guess.

    1. I see the problem as one of “willful ignorance.” With a single individual, that might be a benign thing, depending on who that individual is (I’ll let you work that out to its conclusion). However, willful ignorance in a larger mass of people can have disastrous consequences, leading to large numbers of deaths. This is a problem.

“There are two lasting bequests we can give our children: One is roots, the other is wings.” Teaching children values and giving them the opportunity to excel are essential to good parenting. However, I feel I must also provide my children (and myself) insight into the ones who came before us: our ancestors whose lives and stories have shaped us into who we are. This is my journey; these are their stories…
