I recently ran across a discussion of quantum mechanics from C. S. Lewis.
The older scientists believed that the smallest particles of matter moved according to strict laws: in other words, that the movements of each particle were “interlocked” with the total system of Nature. Some modern scientists seem to think — if I understand them — that this is not so. They seem to think that the individual unit of matter … moves in an indeterminate or random fashion; moves, in fact, “on its own” or “of its own accord.”
He goes on to explain that the macroscopic behavior of matter appears deterministic because the average behavior of billions of particles is very regular. His explanation is remarkably cogent for a professor of medieval literature writing in the 1940’s. He then discusses the philosophical consequences of quantum mechanics.
Now it will be noticed that if this theory is true we have really admitted something other than Nature. If the movements of the individual units is “on their own,” … then those movements are not part of Nature. It would be, indeed, too great a shock to our habits to describe them as super-natural. I think we should call them sub-natural. But all our confidence that Nature has no doors, and no reality outside herself for doors to open on, would have disappeared. There is something outside her, the Subnatural. … And clearly if she thus has a back door opening on the Subnatural, it is quite on the cards that she may also have a front door opening on the Supernatural …
