William Lane Craig is on his
UK tour, and recently had a debate with the atheist philosopher
Stephen Law. Premier Christian Radio seems to be organising the tour, and
they've posted the audio of the debate.
I listened to the debate. A short summary is below, with a longer one underneath the cut.
The debate topic was "Does God exist?". Craig ran some of his standard arguments
- The Kalam Cosmological argument, a First Cause argument which avoids the usual "who made God?" riposte by only claiming that "everything that begins to exist has a cause".
- The moral argument.
- An argument based on the evidence for the Resurrection of Jesus.
Law relied heavily on the
evidential argument from evil, and his own variant of that, the one from his paper
The Evil God Challenge, which Luke Muehlhauser has previously summarised
here. Law has summarised his main argument in the debate
on his own blog.
If you want to see my notes on the whole thing, read on, otherwise,
skip to the end for my thoughts on how both of them did, and how atheists might do better.
( The gory details )How did they do?
Who won? Hard to say, especially as I'm obviously biased. At the very least, Law wasn't crushed in the way that some of Craig's previous opponents have been.
I'm mostly going to offer what I hope is constructive criticism of Law. This is because I'm on his side :-)
Law's first rebuttal sounded a bit hesitant. He seemed to be astonished that Craig had actually claimed that theists don't conclude that God is good from looking at the world and didn't know how to respond to Craig's assertion that it's all about the moral argument.
Law had recovered a bit by his second rebuttal, but even later on, at times he didn't quite seem to have processed Craig's statement that looking at the world didn't provide evidence against either an Evil or a Good God: even after Craig had said that, Law sometimes seemed to be arguing as if Craig had said the opposite.
Craig's not afraid to use explicit
syllogisms or arguments with numbered premises rather than relying on wordy arguments, so laying out the Evil God argument in that form would have allowed people to follow it better.
Law's failure to respond to the Kalam allowed Craig to score against by calling him a strange sort of atheist who believes in a creator (but see armchair generalship, below).
Craig accepts that we should generally be careful about accepting miracle reports but then argues the Jesus's resurrection is special. Law is right to say that Craig's reasons are flimsy, but he needs to say why.
Craig only used for 3 of his usual 5 arguments for God's existence. He left out the fine tuning argument and the argument from religious experience (which he usually turns into something close to an
altar call). Law has written some
strong rebuttals to the experience argument, and Law wondered whether Craig avoided it because of those. It'd be interesting to hear from Craig whether he avoided it for that reason.

In which I play the armchair general with 20-20 hindsight
Craig's claim that theists don't conclude the creator is good from looking at the world sounds well dodgy: you do see Christians saying stuff about how beautiful the world is and how that's evidence for their God. When Craig makes a claim where he seems to deviate from what Christians actually do, it's worth playing that up: "If you're a Christian who thinks that the beauty of the world is evidence for the Christian God, Dr Craig would disagree with you, apparently."
How do you solve a problem like the Kalam?
I'm not sure what I think of Law's refusal to say much about the Kalam (other than that it was also an argument for Evil God). It allowed Craig to score, but it could have ultimately been a good tactic as Craig's previous debates on the Kalam tend to turn into people trading obscure arguments about infinite sets or quoting from popular physics books.
If you're going to use Law's tactic, though, again you need to play it up more: "The title of the debate is 'Does God Exist?', and it's the Christian God that Craig is advocating, not any other possible gods. Craig is a Christian evangelist, the Kalam is there to lead you towards Christianity. But even if you are convinced by the Kalam, you are a long way from Christianity. There are
countless other possibilities which shouldn't be ruled out merely because they're not as familiar as the Christian God you learned about at school, or because believing in them would make you a strange sort of atheist."
Arguments from authority
It's noticeable that Craig's allowed to quote people at length, but as soon as anyone else does, it's an
argument from authority. That should be an easy (and funny) point for an opponent to make: Craig's defence of his moral argument is mostly quotes from people saying they agree with one or other of the premises. If Craig responds that he's quoting competent authorities, ask whether Swinburne or Plantinga are incompetent :-)
The resurrection
Craig didn't seem as polished on the resurrection as he has in the past, perhaps because he was expecting to get into the details and quote some more authorities. Law took it in another direction: just another unexplained weird report, like a UFO sighting that we reasonably assume wasn't caused by aliens without getting into the details of who saw what. All Craig can say about that is that there's no obvious natural explanation (which Law seemed to agree with and which doesn't affect Law's argument) and that there's something special about the context, by which he seems to mean the life of Jesus. That seemed ideal ground for a more specific counter-attack from Law than just calling it "flimsy".
The moral argument
The moral argument is a tough one because people are psychologically attached to both premises. In front of a general audience, I can see why Law wanted to be a bit careful not to deny absolute morality: Craig can then go into his usual routine about how there's nothing wrong with rape on atheism, or whatever.
Arif Ahmed famously did go after Craig on that second premise: "Dr. Craig says that 'objective moral values exist, and I think we all know it'. Now that might pass for an argument at Talbot Theological Seminary, and it might pass for an argument in the White House, but this is Cambridge, and it will not pass for an argument here." But Ahmed was talking in front of philosophy students.
Craig does get away with denying strong feelings, responding to the problem of evil. He says that philosophers are called to think rather than go on feelings, so perhaps that's sauce for the gander: our strong feeling that some things are Just Wrong shouldn't prevent us from thinking about it. If you're going to do that you do need to genuflect in the direction of people's feelings, though, as Craig does.
I think I'd try to unpick the psychological attachment: what looks different in a world where are no moral absolutes of the sort Craig wants when compared with a world where there are? Not much, as far as I can tell: even if they are there, people need some reason to obey them and it's open to them to say "I don't care what's Right". If you somehow discovered that there really were no moral absolutes, would you run out an murder your neighbour?

The segue
Craig accepts that the Kalam establishes the existence of a creator who might be evil, for all the argument tells us, but goes on to say that the moral argument shows that God is good. How does he know that whatever being "grounds" morality is the same being as this creator from the Kalam? Can the "God" in that the "no God means no real morality" premise be someone other than the creator? What is it about being a creator that also grants you morality-grounding powers? It's all pretty mysterious.
Similarly, what is it about the resurrection that links Jesus to the creator and to the morality-grounder?
In both these cases, Craig's relying on the audience's familiarity with Christianity to make the segue from one argument to the next seem obvious, but these are very
burdensome details. The audience's familiarity with this stuff makes them vulnerable to conjunction bias. It's worth trying to get the audience to take an outsider's view of how the arguments work.
Other reactions
This Christian apologist thought Craig lost and came up with his own Evil God version of the moral argument, but thought that not questioning the Kalam made Law a funny sort of atheist.
Randal Rauser, another Christian, hosted
an interesting discussion about Law's choice to only attack God's goodness. If Law is right, has he shown "God does not exist"?
Edit: Gregory Lewis has produced some excellent
argument maps of the debate. I'd recommend those for another view of how it went.
