Catch Up Before You Speak Up

Luke Muehlhauser admonishes his fellow atheists to do a better job of catching up with the current states of various aspects of the scholarly debate between theism and atheism before presuming to publicly debate theists.  He gives a couple instructive examples of failure to do so:

  • In a debate with theist Bill Craig, agnostic Bart Ehrman paraphrased David Hume’s argument that we can’t demonstrate the occurrence of a miracle in the past. Craig responded with a PowerPoint slide showing Bayes’ Theorem, and explained that Ehrman was only considering prior probabilities, when of course he needed to consider the relevant conditional probabilities as well. Ehrman failed to respond to this, and looked as though he had never seen Bayes’ Theorem before. Had Ehrman practiced the virtue of scholarship on this issue, he might have noticed that much of the scholarly work on Hume’s argument in the past two decadeshas involved Bayes’ Theorem. He might also have discovered that the correct response to Craig’s use of Bayes’ Theorem can be found in pages 298-341 of J.H. Sobel’s Logic and Theism.
  • In another debate with Bill Craig, atheist Christopher Hitchens gave this objection: “Who designed the Designer? Don’t you run the risk… of asking ‘Well, where does that come from? And where does that come from?’ and running into an infinite regress?” But this is an elementary misunderstanding in philosophy of science. Why? Because every successful scientific explanation faces the exact same problem. It’s called the “why regress” because no matter what explanation is given of something, you can always still ask “Why?” Craig pointed this out and handily won that part of the debate. Had Hitchens had a passing understanding of science or explanation, he could have avoided looking foolish, and also spent more time onsubstantive objections to theism. (One can give a “Who made God?” objection to theism that has some meat, but that’s not the one Hitchens gave. Hitchens’ objection concerned an infinite regress of explanations, which is just as much a feature of science as it is of theism.)
