Here's what Carrier says about his chapter of The Christian Delusion.
Two of The Christian Delusion's fifteen chapters are mine. The first is Why the Resurrection Is Unbelievable, which is the most definitive refutation of warranted belief in the resurrection I have ever composed. It's a deliberate tour de force, such that I doubt I'll ever have to write another. It even takes down recent attempts to use Bayes' Theorem to argue for the resurrection, and it contextualizes everything so there just isn't any rational basis left for claiming the resurrection is historically proven.
In the next paragraph he refers to both of his contributions as tours de force.
When you talk like that, you had better be able to take out the McGrews. In my brainwashed opinion, that's a chess game he has no chance of winning.
