SHAVING WITH OCCAM’S RAZOR
In the
beginning, God created skies and earth.
Welcome back. Let’s
think about Occam’s Razor.
I remember watching Jupiter once during a high school football
game. It shone
brightly in the sky before kickoff. By the 4th quarter, it appeared to be moving backwards.
When I was a kid, I used to race my younger brother. We’d draw up a finish line. I’d give
him a head start. I would
pass him a few yards before the end. While I
was passing him, he appeared to be going backwards.
To ancients who believed the earth was the fixed, immovable center
of the universe, the appearance of a planet moving backwards must have
contributed to the belief that planets were heavenly beings watching them.
Jupiter appears to be moving backwards because our planet rotates,
but Jupiter also recedes from the sky. It can
vanish for weeks.
An ancient Greek named Ptolemy attempted to explain such celestial
oddities with epi-cycles. He
proposed that planets moved in circles as they moved across the sky.
This earth centered theory, what we call the geocentric theory,
was the prevailing theory of ancient people for millennia. It underlies all Biblical thinking about the cosmos.
This earth centered cosmology, or world view, would eventually be
replaced by a sun centered theory. Now, we do not believe there is a
center to the universe, just our solar system.
This heliocentric theory, first proposed by Nicholas Copernicus,
in the 16h Century, changed everything: philosophy,
politics, religion, and Poland. It put Poland on the intellectual map.
Too bad the earth centered theory was the explanation of the
universe when the Bible was written. That fact has caused a ton of grief
and centuries of bad Bible reading.
Think the Bible is inerrant? This earth centered universe is
one whopping huge error in the Bible. In many places in scripture,
ancient writers wrote that the earth did not move. Upon pain of death, it
did not move by God.
Copernicus was no dummy. He knew
he would be burned at the stake for suggesting the earth moved when the Bible
clearly said it did not. Thus, he arranged for his book Revolution of the Heavenly Orbs to be
published after he died. His
theory set the sun in the middle of the universe and proposed that all planets,
including Earth, orbited the sun.
His theory satisfied the requirement of Occam’s Razor. It did not need a bunch of epicycles to explain planetary motion
in the universe. Once the
sun was in the center of a solar system, the motions of all the planets became
the simplest explanation. Just
because it was the simplest did not mean it was believed.
Look up Galileo’s trial if you want to see how humanity, upon pain
of death, resisted the idea of an earth centered universe.
By the way, when I say universe, I mean a tiny cosmos. Ancient people thought the skies and earth were all there was and
there would ever be. They
could not conceive of a solar system let alone billions of suns, billions of
galaxies, and infinity.
Yahweh was immortal, but not infinite when compared to our God of
love we worship today, who is the ground of Being-itself. Next to our God
in whom everything that is moves and has its being, all other gods are just sky
gods.
Truly, science in general, and Occam’s Razor in particular, are
faith's best friends.
Indeed, when it comes to religion, I apply Occam’s Razor. It cuts off whiskery superstition and idolatry. The Bible thereby inspires faith that is strong and sensible
rather than idolatrous and silly.
If what we know to be true conflicts with our faith, then we need
to take a long hard look at what we believe about how to believe. St.
Augustine said something just like that centuries before I wrote these words.
In the case of the Bible, the problem is not God or the
Bible. The
problem is how we are interpreting the Bible.
As John Crossan has asked the question, and I paraphrase here,
were ancient people so dumb that they wrote the Bible literally and we are so
smart today to read it as symbolic and metaphorical; or were they so smart that
they knew they were writing poetry and we are so dumb we take it literally?
I have on my car a Jesus fish and a Darwin fish. Mine was the first and second car in Chattanooga to have them
joined on one automobile bumper. I put them on my Corolla in 1995.
I hoped to start a trend. A
decade passed, and my indomitable Corolla died underneath an overpass on
Interstate 75. A few
days later I bought a new Fusion.
I stuck a new Darwin fish and a new Jesus fish on that car too and
thus became the second person in Chattanooga to post them on his car. I suppose it takes two to begin a trend.
One day, I was walking out of Best Buy in Chattanooga, when I saw
three teenagers standing behind my car. One of
them pointed to my car and asked me to explain my fish.
I said, “They belong together don’t you think?”
One boy replied, “I don’t see how.”
I asked, “Have you ever read Origin of
Species?”
“Nope.”
“How about the Bible?”
“Some of it. ”
“Well—I,”
These young men sensed a long explanation coming…and they were
probably right…so they dashed off before I could get started.
I relished the opportunity to explain to them how I read The Origin of Species. Why I
knew Darwin was right, and how, like Copernicus’ book, it changed everything.
Nonetheless, I was never leaving God.
Blessings…
