Why is the Universe Comprehensible?

Comprehensible universeStone Age man 10,000 years ago had no use for calculus.

We have pretty much the same Stone Age brain and, with effort, we can understand calculus. And physics. And chemistry. And economics, math, literature, and other complicated topics for which primitive man had no use. These particular skills couldn’t have been selected by evolution.

As Einstein observed, “The most incomprehensible thing about the world is that it is comprehensible.”

The Christian has a ready answer: God did it. Our brains are able to understand the universe because we’re made in God’s image, and he wants us to understand.

A related example: skin

Let’s consider another marvel, animal skin. It can heal after being burned, but it’s possible that getting burned was such a rare event that natural selection didn’t have the chance to select animals for skin able to recover from burns. Worse, evolution has had no time to prepare us for modern injuries such as skin burns by nuclear radiation or from concentrated acids or other nasty chemicals.

And yet human skin does heal after injuries from fire, chemicals, or radiation. Evolution selected for general-purpose skin that responds well to general injuries like cuts, bites, and scrapes, and it’s able to repair after the new injuries as well.

In the same way, it seems to have also selected for a general-purpose brain that could make tools and coordinate hunting parties—and understand calculus and physics. So the quick answer to, “Why did evolution give us a brain that could understand calculus, physics, and the universe?” is, “Why not?”

The Flynn effect is a startling recent example showing how our brain adapts to environments that would be novel not only to the humans of thousands of years ago, but even to the previous generation. For about a century, new stimuli (possibly including new media like movies, TV, and the internet; broader education; or new work challenges) have driven up average IQ scores in the West by three points per decade.

The evolution connection becomes clearer when we consider some of the new fields we’ve entered in the last century or two. We’re comfortable with the everyday physics we see around us—gravity, buoyancy, air pressure, centrifugal force, and so on. But we live in a medium world, and the world of the tiny (cells, atoms, quantum physics) and the enormous (galaxies, black holes, the universe) are described by science that is well validated but often violates our common sense. As physicist Richard Feynman is quoted as saying, “If you think you understand quantum mechanics, you don’t understand quantum mechanics.”

But is the universe comprehensible?

Before we congratulate ourselves too much on how much we can understand, keep in mind that we understand only what we’re capable of understanding. There could be enormous reservoirs of scientific fact that we’re inherently unable to perceive, let alone understand, because of our limited brains—like a red-green color distinction to a color blind person or a joke to a lizard.

The part of the universe that we comprehend isn’t that surprising, and much of what we don’t comprehend may be forever beyond our grasp.

You can’t explain why the tide goes in.

Does the Old Testament Condemn Homosexuality? (2 of 2)

Bible HomosexualityLast time we looked at the Sodom and Gomorrah story. Let’s move on to the book of Leviticus.

You must not have sexual intercourse with a male as one has sexual intercourse with a woman; it is an abomination (Leviticus 18:22).

Sounds pretty damning, but the word “abomination” also describes eating forbidden food (Deut. 14:3), sacrificing blemished animals (Deut. 17:1), performing divination and similar magic (Deut. 18:12), and women wearing men’s clothing (Deut. 22:5). These are ritual abominations.

Making sense of ritual abominations

Mary Douglas clarifies the confusing purity laws in Leviticus, where things are clean or unclean seemingly arbitrarily. She argues that “clean” things are proper members of their category. A proper fish has fins and scales, so that makes it an abomination to eat improper sea animals like clams and shrimp. A proper land animal—one that is part of civilized society—is cloven hoofed and cud chewing like a cow or goat. To be clean, any animal or wild game must share these characteristics—hence no rabbits (not cloven hoofed) or pigs (not cud chewers). “Unclean” means “imperfect members of its class.”

A sacrifice must be a perfect animal, hence no blemishes. A priest must be a perfect man, hence he can’t be blind or lame. Don’t mix seeds in a field; don’t mix textiles in a garment.

Homosexuality fits easily into this taxonomy—proper sex is man with woman, so man/man or man/animal sex is explicitly forbidden. But it’s ritually forbidden, not forbidden because of any innate harm.

Leviticus, take 2

Here’s another popular bludgeon:

If a man has sexual intercourse with a male as one has sexual intercourse with a woman, the two of them have committed an abomination. They must be put to death; their blood guilt is on themselves (Lev. 20:13).

First, note that this again is nothing more than ritual abomination.

Second, note the punishment. Don’t point to the Bible to identify the crime but then ignore its penalty. There is no crime if there is no penalty. Do modern Christians truly think that the appropriate response to male homosexuality is death?

Third, note what else this chapter demands: unclean animals can’t be eaten (20:25), exile for a couple that has sex during the woman’s period (:18), death to spiritual mediums (:27), death for adultery (:10), and death for anyone who curses his father or mother (:9). It comes as a package of out-of-date tribal customs—with what justification can a Christian select the anti-homosexual verse and ignore the rest?

Cafeteria Christianity

If Jesus was the once-and-for-all sacrifice that did away with the need for the Old Testament ritual laws (Heb. 7:11–12 and 8:6–13), then get rid of them all.

God said, “I will establish my covenant as an everlasting covenant between me and you and your descendants after you for the generations to come, to be your God and the God of your descendants after you” (Gen. 17:7). Verses like this would saddle Christians with all the Old Testament customs, from the sacrifices to the crazy stuff like genocide that they’d like to distance themselves from, and they’ll say that these verses apply to Jews only. Fair enough—then stop cherry picking Old Testament passages from sections of the Old Testament that don’t apply to you.

This selective reading reminds me of Rev. O’Neal Dozier, an honorary co-chair of Rick Santorum’s election committee, who said that homosexuality is the “paramount of sins” and that it is “something so nasty and disgusting that it makes God want to vomit.” My first impulse to this energetic condemnation is to wonder if Haggard’s Law applies, but more to the point, why is homosexuality at the top of the list? Why should it be any worse than any other “abomination” such as eating shrimp, telling a fortune, or a woman wearing pants? (Unless, of course, Rev. Dozier is simply using the Bible as a sock puppet to have it speak his opinions, which is certainly where the evidence points.)

Apologists like Dozier who say that the Bible is clear in its rejection of homosexuality won’t say the same thing about the Bible’s support for genocide, slavery, and polygamy. They’ll say, “Okay, slow down and let me tell you why the surface reading isn’t correct.” The predicament for today’s Christian is the clash between modern morality and the warlike culture of the early Israelites.

A common response to God’s embarrassing actions in the Old Testament is to say that he is mysterious and inscrutable to our simple human minds. But then these same Christians will contradict themselves and say with certainty that God is against homosexuality, abortion, and taxes.

Apologists who pick and choose which commandments must be taken literally are beating the copper of the Bible against the anvil of their faith. Shouldn’t it be the other way around? Why is the atheist the one letting the Bible speak for itself?

Or if the Bible is simply the sock puppet used to give an argument credibility, I’d appreciate Christians dropping the middleman, admitting that their beliefs come from their innate moral sense, and defending them as such.

Morality is doing what is right regardless of what we are told. 
Religious dogma is doing what we are told regardless of what is right.

Does the Old Testament Condemn Homosexuality?

Bible homosexualityThe Sodom and Gomorrah story is where many Christians point when arguing that God rejects homosexuality. That’s a lot to place on just six verses. Let’s look at them:

All the men from every part of the city of Sodom—both young and old—surrounded the house. They called to Lot, “Where are the men who came to you tonight? Bring them out to us so that we can have sex with them [literally: so that we can know them].”

Lot went outside to meet them and shut the door behind him and said, “No, my friends. Don’t do this wicked thing. Look, I have two daughters who have never slept with a man. Let me bring them out to you, and you can do what you like with them. But don’t do anything to these men, for they have come under the protection of my roof.”

“Get out of our way,” they replied. “This fellow came here as a foreigner, and now he wants to play the judge! We’ll treat you worse than them.” They kept bringing pressure on Lot and moved forward to break down the door. (Gen. 19:4–9, NET Bible)

There are a couple of interpretations of this story beyond the typical conclusion that homosexuality is so bad that it gets your town destroyed.

Did angels have secret knowledge?

We’re so familiar with to “know” in the Bible meaning “to have sex with” that we forget that sometimes a cigar is just a cigar. The Hebrew word in question is used 947 times in the King James Version, most of which have nothing to do with sex. For example, “When you eat from [the fruit] your eyes will be opened, and you will be like God, knowing good and evil” (Gen. 3:5), “The man has now become like one of us, knowing good and evil” (Gen. 3:22), and so on.

If that’s the interpretation, what might the townspeople have wanted to know? Robert Price suggested that the idea of supernatural visitors wouldn’t have been too surprising within that culture. It was a violent time, and any military advantage for their town would have been helpful. Angels could have provided important information.

What to me undercuts this is Lot’s response, “Don’t do this wicked thing,” which isn’t in keeping with a request for knowledge, though it’s conceivable that this was added by later copyists. But if we conclude that gang rape is commonplace for this community, why is this godly man still living there? The story leaves this unclear.

Does the homosexual argument even make sense?

Let’s consider a second interpretation: if the townsmen were homosexual, why would Lot have offered them his daughters? Perhaps instead they were simply violent bullies who wanted to use rape for domination or humiliation. Isn’t this how rape is sometimes used in prison?

(That Lot volunteered his virgin daughters as if they were merely expensive possessions raises other issues, but let’s not go there.)

One unambiguous conclusion from the story is that gang rape is bad. Okay, no disagreement there. But what critique does this give of a loving homosexual relationship, which is the issue that society is addressing today?

Next time: we’ll conclude with Part 2.

Christian Magic Power Doesn’t Work if You Don’t Believe It

Christian Magic PowerThe Friendly Atheist recently highlighted the video of a Finnish karate master defeating opponents without a punch or kick. He used what he calls “Empty Force.”

You can, too—for a fee.

The video shows opponents falling to the floor, but these were students of the master. When he tried his magic on skeptics, nothing happened.

The Friendly Atheist noted that the karate students falling to the ground in response to the master’s touch was like Benny Hinn’s celebrated public healings, where sick believers are “slain in the Spirit” as they fall back and writhe on the floor in response to Hinn’s magic wave. But you have to be a believer for it to work—or be in on the scam.

What if the opponent isn’t your own student?

Another example is Kiai Master Ryukerin, who has a touchless energy technique similar to Empty Force. Here’s a demonstration of the master sparring with and knocking over his students.

It looks like a stunt but is still intriguing. How would this work in an actual fight? Surprisingly, Master Ryukerin was confident enough not only to offer to fight anyone but to put up prize money. Another fighter accepted the challenge, and the results are predictable. Though respectful, he quickly thrashed the old man (another view here). The magic force field was only in the mind of his students and had no hold over an outsider.

The Christian energy field

The naïve Christian street preacher or door-knocking missionary is similar to Master Ryukerin. They care what the Bible says, so they’ll support their argument with Bible quotes. They had a compelling personal experience of Jesus, so they’ll share it. They are swayed by emotional (rather than intellectual) arguments, so they’ll use them.

They’ll talk about how the church community is important to them, or that the pastor is charismatic. It works on them, so it should work on others, right?

But this has as much impact on skeptics who demand evidence as Master Ryukerin’s energy field does to a fighter outside his school.

More experienced evangelists faced with such an atheist may try intellectual arguments or move on to look for easier conquests.

Christians know what I’m talking about when it comes to cult leaders like Jim Jones or disgraced televangelists like Jim Bakker. How could people have not seen through them? But, of course, to the people in their circles of influence, these frauds were very persuasive.

As was Master Ryukerin to his students.

is what stops you from raping and murdering,
that doesn’t make you a good person,
that makes you a sociopath on a leash.

Christians: Why You Need an Atheist Speaker at Your Next Conference

I read or listen to lots of Christian apologists. Frank Turek. Norm Geisler. Dinesh D’Souza. William Lane Craig. Gary Habermas. Mike Licona. Jim Wallace. Greg Koukl. Peter Kreeft.

I went to John Warrick Montgomery’s two-week Apologetics Academy in Strasbourg, France in 2011. I want to hear the best that Christian apologetics has to offer.

The reverse is rarely true.

Christian conferences

I see the ads for Christian apologetics conferences that promise to equip dedicated Christians to win souls for Christ. Sometimes they cover arguments for a historical Jesus. Or review scientific arguments that can be used to argue for a deity behind nature. Or even role play interaction with mock atheists.

It’s not enough. They need to hear from an actual atheist. A faux atheist is no foe.

To me, their refusal to invite one means that conference organizers don’t trust their material to carry the day. They’re afraid that they’ll get embarrassed or upstaged or that the attendees would get freaked out or overwhelmed with material that’s just too real.

But then how well do they prepare attendees? If the conference must tiptoe through the material to avoid the difficult topics, how will newly minted apologists do when they get out and talk to real, live atheists? If you hope that God will give you the right words as he did with Moses, you are setting yourself up for embarrassment.

If someone wants apologetics lite, they can read a book, but a conference should ramp it up. Attendees shouldn’t be spoon-fed straw man arguments but given the real thing.

In this blog, I’ve responded to many Christian arguments—from books, interviews, articles, blog posts, podcasts, lectures, and debates. It’s one of my favorite kinds of posts because they pretty much write themselves. Christians’ arguments are easy to refute. I’ve seen enough to know that the good stuff isn’t kept secret, like magic tricks, and whispered to worthy initiates. If you’re counting on an apologetics conference to show you the landscape, you will be disappointed. I’ve heard the good stuff, and it’s not very good.

My proposal

The next time you see a notice for an apologetics conference, tell the organizing team to invite me to speak, either in a debate or with a lecture.

I can educate the audience about atheism. (Yes, atheists have purpose and morality. No, atheists don’t see their worldview as empty or hopeless.) I can argue for same-sex marriage and abortion rights. I can attack intellectual arguments for Christianity, and I can provide positive arguments for atheism. And then you get the last word.

The Christian arguments will be tested in the field. Shouldn’t they be tested in the conference?

My fee: $0

Give me an audience of 50 or more, and I’ll do it for free. Just cover my expenses. I’m meeting you more than halfway—you donate expenses, and I’ll donate a day or a weekend of my time plus preparation.

Read my books and blog to see how I think. I’ll even provide my books to attendees at cost. If you want someone with a higher profile, that’s great. I’ll be happy to make suggestions.

You think that after an atheist presents the best that that worldview has to offer, you can give your audience an adequate response? Great—then an atheist would be an asset to the conference.

You know how to reach me.
