Uniformitarianism is the assumption that the laws of nature are unchanged across space and time. For example, many natural laws rely on the speed of light being constant everywhere and at every time in the history of the universe. Assumptions such as this are accepted by most scientists because they produce verifiable theories, especially in geology and astronomy. Furthermore, there is no scientific evidence to suggest that natural laws have been changing.

Christians will sometimes criticize uniformitarianism because it disproves the idea of a 6,000 year-old universe. Indeed, radiocarbon dating and astronomical observations suggest a much older universe, and these findings can only be dismissed by questioning the perennial validity of the scientific laws they are based on.

When asked how the laws of nature changed, Christians contend that God did it without leaving any evidence behind. Thus, one could make the equally unsupported counter-claim that a natural law or process that we haven't discovered yet (rather than God) caused the Earth to be 6,000 years old.

Uniformitarianism in Geology

Ockham's Razor

Ockham's razor is the principle that the best explanation for an observation is that which makes the fewest assumptions. Scientists obey Ockham's razor by assuming that the speed of light, the rate of radioactive decay, and all other natural laws operate today as they did millions of years ago. Indeed, until there is evidence to suggest otherwise, uniformitarianism is the common-sense position because it makes the fewest assumptions.

By stating that natural laws were different in the past, Christians are making superfluous assumptions, including:

  1. Natural laws can change over time.
  2. There is undiscovered evidence for this change.
  3. Something exists or existed that could have caused the change.
  4. The Abrahamic God is the cause.
  5. The Abrahamic God had a reason for causing the change.

The end result could be called Ockham's duct tape because of the number of unsupported claims that are used to hold the theory together.

Sometimes Christians will present the Bible as evidence that the Earth is 6,000 years old. Perhaps also, Alice in Wonderland is evidence that the laws of nature were different in a 19th century rabbit hole in Oxford. Unfortunately, writing something down doesn't make it true. Not even science textbooks describe truths. Science describes experiments and their associated uncertainties that have been performed to explain the observable world. These experiments can be recreated at home or in a laboratory so that people can test the explanations for themselves. The experimenters state their assumptions, and accept that if the assumptions were ever proven wrong, the experiment would be invalid.

Sometimes we do experiments just to test if our assumptions are reasonable.

Assumptions in Science

Science does not suppose the irrelevance of the assumptions it is based on. Religion does, and that is the key difference between the two philosophies. In science, assumptions are a reason for doubt; an addendum that the results could still be wrong. If the assumption is proven wrong later, scientific findings that rely on it will be thrown away.

Therefore, uniformitarianism is not presented as an absolute truth. As we cannot directly test conditions in the deep past, experiments assume uniformity in order to further our current understanding of the universe. The question of uniformity will be returned to when experimental tools are capable of addressing it. This doesn't mean our current understanding is flawed. Indeed, scientific theories that assume uniformity appear to accurately model our observations.

In fact, assuming uniformity is currently the best way to test if it is wrong. Experiments are performed to test predictions and, therefore, they also test the assumptions those predictions are based on. If predictions turn out to be false, assumptions such as uniformity can be brought into question.

Christian Misunderstandings

Unfortunately, Christians appear to view science as a competing religion with a competing set of absolute truths. For example, some scientists have theorized that the universe popped into existence from a state of nothingness. As a result, Christians often claim that scientists believe this explanation en masse. However, it's unlikely that any scientist would imbue this theory with belief; it is merely a slightly better theory than creationism because it makes one less assumption (it doesn't require God to make it pop). Even the Big Bang, evolution, and general relativity are still only theories. Many scientists will commit to believing these theories because of the substantial supporting evidence, though the possibility of their falsity is never completely dismissed.

The Bible shouldn't be used to pick and choose the science we accept.

The scientific assumption of uniformitarianism is criticized by Christians who are motivated to reconcile the differences between irrefutable scientific observations and the explanations given in the Bible. When scientific endeavor leads to unwelcome discoveries, the findings are ignored or attacked by Christians for suggesting what is seen as a competing set of absolute truths.

Though science is only as accurate as the assumptions it is based on; religion is the will to fall short of this standard. Indeed, an opinion based on no evidence is not equal to an opinion based on mountains of evidence, especially when the former ignores the entirety of the latter. If, as a result, science fails to recreate the deities and creation stories that your imagination demands, it is not science that is limited; rather, it is your expectations that are inflated. Science is a tool for reducing uncertainty, not eliminating it. It takes a brave person to face the uncertainties of our existence, and a coward to wish them away with theoretical absurdities.

      I agree that they don't `need' to compete. The problem is religions have traditionally focused on providing definitive answers to questions that fall under the remit of science. If a religious person said, "I believe in God", that might be fine for some. They could still perform all manner of scientific research in an objective way (I know some Muslim scientists who do fine). But, beyond mere theistic belief lies all the other scriptural garbage. Opposition to things like evolution, abortion, stem-cell research, the origin of morality, etc.

      However, I would say that faith in God is incompatible with science too. It's an unnecessary assumption based on no evidence, and that is completely alien to science. They don't need to compete, but they're certainly not compatible at any deep level of understanding. When you say that religions can impart meaning, I agree. Just like any story can inform people about right and wrong, the Bible and Qu'ran are no different. But... none of that requires one to faithfully believe in a supernatural being. That, if I'm not mistaken, is the essence of what religion is, though I realize there is some debate on that. For example, what would you categorize Wicca as? Some would say Buddhism is a philosophy rather than a religion, for example.

      Anyway, I wouldn't define a belief in the efficacy of certain stories and myths as making someone religious. Also, I would say that psychological research is doing a lot to help us understand why certain stories are appealing to us. This may lead to the creation of more meaningful stories in future. Science fiction, for example, is very good at revealing and teaching us about the human condition. I share Dawkins' belief that science can be beautiful if we allow it to be, and if we teach it in the right way.

      Ultimately, if we learn how our minds and bodies work, we can become more than what we are. We can conquer our primitive drives. For me, that is a greater motivation than reveling in stagnation, however joyous. You can pop a pill and make yourself happy, or you can believe heaven exists and get the same effect. Like flicking a switch in our heads; we're a slave to these comforts (in my opinion).

      See, I think religion and science don't need to compete; just like art and science don't need to compete. An abstract painting can have truth and meaning, even if it's not a literal interpretation of something that actually exists.I think people are going to move away from orthodoxy and dogma, and more toward religions that do not take myth as literal happenings, but as stories from which we can draw ancient wisdom and meaning because (as Joseph Campbell puts it) they convey the human experience. I think they can co-exist in their rightful places. Religion needs to make way for science to do it's thing, to find the facts and explain things for us, and bring us advancement and progress; and science needs to stand back and realize that the human psyche is complex, and that truth and meaning are not exclusively found or adequately expressed in literal, provable, rote facts. Like your heart bursting with love when you hold your newborn child in your arms for the first time (or, not to mention, look down upon your child in his coffin with your heart breaking) and the mere understanding of chemical reactions just doesn't do justice to the experience for the human mind. We need to celebrate, or we need to mourn-- the majority of people throughout the ages feel the desperate need for religion and spirituality as an outlet for that, to feel connected to others, for rites of passage to go through the transitions and such-- that clinical explanation of a chemical reaction in the brain causing rushing hormones just doesn't do justice to certain human experiences. I don't see what's unhealthy about that; like most things, it can be taken to unhealthy places. I wouldn't compare it to morphine; I'd compare it to diet and exercise-- a basic need, and good for people overall, but can be taken to an unhealthy place.

      I think you've hit the nail on the head Wiccan. As science advances to the point at which scientific knowledge becomes common sense, religions are being forced to reinterpret and revise scripture to cohere with what is plain to see. In the case of uniformitarianism, Christians have found what they see as a weakness in science, and (some) are attempting to exploit it by claiming that it `must' be wrong. Of course, other Christians dismiss the notion of a 6000 year old Earth. They do what Christians have been doing for the past 500 years (reinterpretation and revision).

      It was Dawkins who first coined the phrase `God of the Gaps'. Perhaps this is `God of the Stopgaps', because it's only a matter of time before the new interpretation is shown to be just as foolish.

      Personally, I don't believe religion and science are compatible. One depends on the existence of certainties, and the other depends on everything being uncertain (to however small a degree).

      I agree that religion will die out as science answers our questions about the world. I think that's a good thing, though, as I've said in my recent hub, religion provides a lot of people with comfort. I don't believe this comfort is healthy (any more than morphine is healthy), but I do believe it needs to be replaced. Either that, or root cause of their unhappiness needs to be addressed before it becomes a problem.

      Thanks for commenting fpherj48, I'm glad you found it interesting. Much of this hub comes from my science background and education, though the reason for writing it was a discussion I had on google+ about a year ago. The other person was a Christian who was trying to use uniformitarianism to dismiss scientific findings. I saved the discussion to my computer and made a note to return to it. Many of my hubs come from debates I've had down the years. I think it's better to wait a while before writing them up though. `Reactionary' articles never seem to work.

      This is interesting and well written. I think it's sad that so many feel the need to dismiss science and insist that scripture must be inerrant, including creationism. Just like religious people finally accepted that the Sun was the center of the universe, not the Earth, eventually they're going to have to start accepting the mounting evidence for things like evolution. Ultimately, this is going to destroy a lot of people's faith in their religion when they can no longer deny the facts, because they'll have been raised with an ultimatum that it must be either/or-- religion vs. science. I've always believed that religion and science can go hand in hand; but people get so hung up on details and 'being right' it kind of misses the point of religion entirely. I enjoyed reading this, voted up.

      Hey chefsref,

      Evolution (et al) are theories, but of course, not all theories are equally well supported by evidence. There is nothing close to competing with evolution in terms of explaining the data. Like you say, it will remain until someone finds something better. Christians interpret this as meaning evolution is worthless when compared to things that have "stood the test of time" (like the Bible)... which is where the fundamental difference is I think. For a scientist, a crackpot story written 2000 years ago is no more truthful than one written yesterday. Even the worst theory destroys the Bible because, to be called a theory, it has to make verifiable claims based on observable phenomena. Cheers for commenting.

      Hey Thomas

      I think it is sad that in the US the Evangelicals promote religious dogma as absolute fact while any evidence pointing to differing conclusions is dismissed as irrelevant. Pretty much the exact opposite of Uniformitarianism.

      Saying evolution (et al) is "only a theory" dismisses almost all scientific discoveries. Any theory is an explanation of the evidence based on observation and experimentation. Once accepted as the best theory, it remains until someone offers a better theory that explains the evidence.

      On the other hand, life is simpler if you have absolute truth, it becomes easy to dismiss facts and evidence.

      Thanks Positron Wildhawk. Well, 100 hubs was my target, but I have a couple more planned. After that, I might try some lengthier works of fiction elsewhere.

      Very interesting - voted up. Another fascinating science vs religion conflict.

      Congratulations on your 100th hub. Long may it continue!
