Christianity, Science & C.S. Lewis

April 28, 2021

Casual readers of C.S. Lewis are not always familiar with his supremely balanced view of science and faith.

In a world where skeptics allege science and religious faith are incompatible, Lewis upheld the orthodox Christian understanding that Christianity and true science are 100% compatible. The problem arises when people attempt to use science to explore matters science cannot address.

In “C.S. Lewis and How Christians Should Think about Science,” we read that “C.S. Lewis has written extensively on science or specifically on how believers should think about science. Lewis himself was not antiscience. But he had grave concerns about the use of science to either manipulate nature or validate worldviews based on reductionism or naturalism.”

I would like to emphasize this warning, by adding three simple letters. C.S. Lewis “had grave concerns about the misuse of science.” And so should we all.

In Mere Christianity, C.S. Lewis describes science’s proper role.

Science works by experiments. It watches how things behave. Every scientific statement in the long run, however complicated it looks, really means something like, “I pointed the telescope to such and such a part of the sky at 2:20 a.m. on January 15th and saw so-and-so,” or, “I put some of this stuff in a pot and heated it to such-and-such a temperature and it did so-and-so.” Do not think I am saying anything against science: I am only saying what its job is.

And the more scientific a man is, the more (I believe) he would agree with me that this is the job of science—and a very useful and necessary job it is too. But why anything comes to be there at all, and whether there is anything behind the things science observes—something of a different kind—this is not a scientific question. If there is “Something Behind,” then either it will have to remain altogether unknown to men or else make itself known in some different way.

The statement that there is any such thing, and the statement that there is no such thing, are neither of them statements that science can make. And real scientists do not usually make them. It is usually the journalists and popular novelists who have picked up a few odds and ends of half-baked science from textbooks who go in for them. After all, it is really a matter of common sense. Supposing science ever became complete so that it knew every single thing in the whole universe. Is it not plain that the questions, “Why is there a universe?” “Why does it go on as it does?” “Has it any meaning?” would remain just as they were?

There are, of course, many, many thousands of scientists who are Christians.

I recently read an interesting article on the Society of Roman Catholic Scientists. I commend it to everyone, whatever your religious affiliation (or lack thereof). It is entitled “Christianity in Scientific Mythology,” and begins with the author saying,

It shocks many people to find out that I am both an astrophysicist and a religious believer.  It shocks some of my fellow astrophysicists and even some of my fellow Catholics. . . . But why should this be?  Why should it be a surprise that someone whose chosen profession is the scientific study of the universe is also a person of faith? Why the perception of conflict?  Is it intrinsic to the business of science that it be “at odds” with religion?

Despite the fact that Professor Clemens fails to mention C.S. Lewis in his essay, he makes many valid points. The first lays a solid foundation for his message, and dispels a patently obvious, but seldom acknowledged, fact.

One of the defects of contemporary culture is the undue and unhealthy reverence we show toward scientists.  The public imagines scientists to be too smart to disagree with, too objective to be swayed by emotion or bias, and experts on every subject they choose to talk about.  None of these things is true, of course, and the unquestioning acceptance of these notions does great harm.

C.S. Lewis’ Concept of Scientism

Like all sane people, C.S. Lewis appreciated the great value of science. What he warned against was a sort of deification [my word] of science. It is like the elevation of scientific mythology to the status of ultimate religious truth, able to answer even metaphysical questions with certitude.

If you would like to read more on this subject, consider the following articles:

Science and Scientism: The Prophetic Vision of C.S. Lewis

C.S. Lewis: Science and Scientism

C.S. Lewis and the Religion of Science

C.S. Lewis on Science, Evolution, and Evolutionism

Another worthwhile article, published in the journal of Science and Christian Belief, is available at “Science and Religion in the Writings of C.S. Lewis.”

As a person of faith, albeit not a scientist, I concur wholeheartedly with C.S. Lewis. In the following passage from The Weight of Glory, Lewis makes a profound point, although it may require more than a single reading to comprehend. You may wish to read the entire essay to see how he builds up to this observation, but I offer it here on its own merits.

The waking world is judged more real because it can thus contain the dreaming world: the dreaming world is judged less real because it cannot contain the waking one. For the same reason I am certain that in passing from the scientific point of view to the theological, I have passed from dream to waking. Christian theology can fit in science, art, morality, and the sub-Christian religious. The scientific point of view cannot fit in any of these things, not even science itself.
