The Moon Isn’t Made of Green Cheese … Is It?

A moon made of cheese is cut, and a wedge is pulled awayEaster has recently passed, and I’d like to rerun a post on the resurrection.

In a fable going back centuries within various cultures, a simpleton sees the reflection of the full moon in water and imagines that it’s a wheel of green (that is, young) cheese. It’s a tale that we often pass on to our children and that we discard with time, like belief in the Easter Bunny.

But how do you know that the moon isn’t made of green cheese?

Physicist Sean M. Carroll addressed this question recently. After a few moments exploring physical issues like the moon’s mass, volume, and density and the (dissimilar) density of cheese, he gave this frank broadside:

The answer is that it’s absurd to think the moon is made of green cheese.

He goes on to say that we understand how the planets were formed and how the solar system works. There simply is no reason to suppose that the moon is made of green cheese and plenty of reasons to suppose that it’s not.

This is not a proof, there is no metaphysical proof, like you can prove a statement in logic or math that the moon is not made of green cheese. But science nevertheless passes judgments on claims based on how well they fit in with the rest of our theoretical understanding.

Bringing this thinking into the domain of this blog, how do we know that Jesus wasn’t raised from the dead? The answer is the same: it’s absurd to think that Jesus was raised from the dead.

  • We know how death works. We see it in plants and animals, and we know that when they’re gone, they’re just gone. Rats don’t have souls. Zebras don’t go to heaven. There’s no reason to suppose that it works any differently for our favorite animal, Homo sapiens, and plenty of reasons to suppose that it works the same.
  • We know about ancient manuscripts. Lots of cultures wrote their ancient myths, and many of these are older than the books of the Old Testament: Gilgamesh (Sumerian), Enûma Eliš (Babylonian), Ramayana (Hindu), Iliad (Greek), Beowulf (Anglo-Saxon), Popol Vuh (Mayan), and so on. For whatever reason, people write miracle stories, and we have a large and well-populated bin labeled “Mythology” in which to put stories like those in the Bible.
  • We know about how stories and legends grow with time. We may have heard of Charles Darwin’s deathbed conversion to Christianity (false). Or that a decent fraction of Americans thought that President Obama is a Muslim. Or that aliens crash-landed in Roswell, New Mexico. Or that a new star appeared in the night sky with the birth of North Korea’s Kim Jong Il. In our own time, urban legends so neatly fit a standard pattern, that simple rules help identify them.
  • We know that humans invent religions. There are 42,000 denominations of Christianity alone, for example, and uncountably many versions of the myriad religions invented through history.

Natural explanations are sufficient to explain Christianity.

Might the moon actually be made of cheese? Science doesn’t make unconditional statements, but we can assume the contrary with about as much confidence as we have in any scientific statement.

Might Jesus have been raised from the dead? Sure, it’s possible, but that’s not where the facts point. Aside from satisfying a preconception, why imagine that this is the case?

Principle of Analogy

I recently found the name for a simple and common sense idea that is often abused in apologetics circles, the Principle of Analogy.

Bob Price described it this way:

We don’t know that things have always happened the way they do now.  But unless we assume that, we can’t infer anything about the past.  If we don’t assume that physics and chemistry have always worked by the same laws, we’re just going to believe anything any nut says.  …

[Imagine being confronted with the claim,] “I met a guy today who turned into a werewolf when the full moon came out.”  Wait a minute—I know of no one who has ever seriously claimed to have ever seen that, so there is no analogy to current day experience to such a claim.  But … there are fictional stories and movies where that happens.  I bet this really is one of those.  (Source)

How do we categorize a miracle claim from history?  What’s it analogous to?  Does it look like the plausible activities of ordinary people or does it look like legend?  You can’t say for sure, of course, but which bin does this claim best fit into?

Did a winged horse carry Muhammad?  Did Joseph Smith find golden plates with the help of the angel Moroni?  Can faith healers cure illness that modern medicine can’t?  Science has no analogy to these claims, but mythology and legend do.

Incredibly, I’ve heard Christians reject this principle and argue that an atheist must bring positive evidence against their claims.  Say for example that the question is whether Jesus raised Lazarus from the dead.  The Christian points to this story in John—that’s the evidence in favor.  And then he says, “So where’s your evidence against?”

Of course, I have no direct evidence against this particular event.  I have no direct evidence that Jesus didn’t raise Lazarus or that Merlin wasn’t a shape-shifting wizard or that Paul Bunyan didn’t exist.  The plausibility test that we all use helps ensure that we don’t simply believe everything we hear or read.  Well, all of us, I guess, except someone who’s eager to make exceptions to preserve a preconception.

Something can violate the Principle of Analogy only with substantial evidence.  The claim “I can see through opaque objects” properly fit into the magical category until Wilhelm Röntgen demonstrated x-rays.

Until we have an analogy to a miracle story, it properly belongs in the magical category as well.
