I got the same reaction from that closing statement as you, in fact, I thought to myself "Funny, it seems to me that it would be the Objectivists (and/or atheists) who would get a bad taste from the notion that Faith and Reason occupy the same regions of the brain."

That said, historically, by and large, Catholicism (in general; there's no accounting for select individuals) has always been the Faith most accepting of Scientific discovery, regardless of how seemingly contrary to the Faith. So it's no wonder to me that this would be the case for us. After all, Gregor Mendel, the Father of Genetics, was a Catholic priest.
