Pete might start at the beginning with an introductory course in practical reasoning.

It's the sort of logic used by both Darwin and Aquinas to help them get down to specifics. Completely nonpartisan, nondenominational, and unbiased.

If the ability to reason carefully doesn't appeal to you (or to GfS, if he's out there), there really is nothing to discuss. You'll believe what you like because it makes you feel good, regardless.

Unfortunately, scientists have to believe or suspect - on the basis of evidence - plenty of things that don't make them feel good at all.
