Not magic

I got in a friendly argument online a few days ago with someone who finds my reliance on the scientific method "limited."  (His word.)

He accepts science, he said, but added that if that's your only way of understanding, there's stuff you'll miss.  "There are features of reality that science can't, or won't, study," he said.  "Science deals with what is tangible and quantifiable; there are other ways of knowing that allow you to access what is intangible and unquantifiable.  Without those, you're ignoring half of the universe."

The whole thing put me in mind of biologist Stephen Jay Gould's idea of non-overlapping magisteria -- that there are different domains of inquiry, and science only addresses one of them.  (Gould considered religion to be one of those other magisteria -- and that science and religion could coexist just fine unless one chose to tread on the other's toes.)

The problem with this is that science has been progressively chewing away at the other magisteria, as more and more of the universe is explained scientifically.  Phenomena that were thought to be utterly mysterious are now accounted for by rational scientific models -- heredity and tectonic activity are just two of many examples.  (In some realms -- such as legal documents -- we still have vestiges of this older way of thinking, in calling certain natural occurrences "acts of God.")

Even some religious people are uncomfortable with this approach.  Theologian Dietrich Bonhoeffer referred to it as "the God of the gaps," and pointed out the most obvious problem with it:

How wrong it is to use God as a stop-gap for the incompleteness of our knowledge.  If in fact the frontiers of knowledge are being pushed further and further back (and that is bound to be the case), then God is being pushed back with them, and is therefore continually in retreat.  We are to find God in what we know, not in what we don't know.

So accounting for a phenomenon using some not necessarily religious, but non-scientific, explanation is basically nothing more than the argument from ignorance; "we don't yet know how this works, so it must be beyond science to explain."

Emphasis on the word "yet."

Take, for example, the bleeding polenta of Padua.

In 1819, there were reports of what some were calling a miracle and others a work of Satan -- the appearance of what seemed to be drops of blood in polenta, bread, and other starchy food.  Whatever it was did look convincingly like blood, as you can see from the above photograph.  Italy in the nineteenth century was a devoutly Roman Catholic country, and the phenomenon was considered a "sign" (of what, depended upon whom you asked; some thought it was a harbinger of the end of the world, unsurprising considering how often this claim still comes up).

But a chemist at the University of Padua, Bartolomeo Bizio, firmly believed that there had to be a natural, rational cause for the spots.  He obtained samples of the red-stained food, and very quickly discovered two things: (1) if he put a drop of the red material on a sterile dish of starch, it rapidly developed red streaks as well; and (2) when he looked at some of it under a microscope, he saw cells -- but not blood cells.  Whatever it was might have the same color as blood, but it wasn't blood.

It was, in fact, a bacteria, which Bizio named Serratia marcescens -- the genus name after Florentine biologist Serafino Serrati, and the species name from a Latin word meaning "decay."  The red color comes from an organic compound called prodiogiosin.  Serratia marcescens has been found to be a more-or-less ubiquitous bacteria in soils and on moist surfaces -- it's responsible for the pinkish color that sometimes shows up in spoiled food and around the edges of unscrubbed sinks and drains.

It's a simple example, but it does show how "it happened because of something supernatural" is not really an explanation at all.  It is, in fact, a way to stop thinking.  Bizio started from the standpoint of "let's assume this has a rational cause," and it was only because that was his baseline assumption that he was able to take the step forward into understanding it.

Now, don't misunderstand me; it's not that I'm sure that science can explain everything, and it's certainly not because I think science has explained everything.  It's more that before we jump to a paranormal answer, we'd better make sure we've ruled out all the scientific ones first.  Because in the past two hundred years, the other magisteria have gradually shrunk as science has explained more and more of the universe.

As the inimitable Tim Minchin put it: "Throughout history, every mystery ever solved has turned out to be -- not magic."
