A redated post.
In response to Mr. Aspray, I would hope that he gets the chance to read the second chapter of my book, "Assessing Apologetic Arguments." There I distinguish three positions with respect to the relation between faith and reason, fideism, which denies that religious beliefs are open to rational assessment, strong rationalism, which says that in order for it to be rational to believe something in religion we should have a proof that at least ought to be acceptable to every reasonable person, and critical rationalism, which says that although we should have good reasons for our beliefs, we should not expect that the proof we expect will, or even should, be acceptable to every rational person. I endorse the third option, but not the second, in spite of spending the remainder of the book providing reasons for preferring theism to naturalism. (In passing, it looks as if Richard Carrier is a strong rationalist who keeps taking me to task for failing to successfully shoulder the strong rationalist's burden, something I explicitly indicate probably cannot be done. And then I have seen commentators who think maybe I claim to little for my arguments).
I believe strongly in reason; I just don't believe that there is a neutral, emotion-free perspective from which to reason. I expect people will reason from where they are intellectually, not from some Cartesian/Archimedean point of absolute zero.
A lot of people like to read Lewis's apologetics more rationalistically than it really is, and then say that since he met a real philosopher in Anscombe, he gave up the business of making religion rational. That's a bunch on nonsense, a crock of manure eight feet high. Lewis emphasized both reason and the emotions throughout his career, and did an excellent job of avoiding the Star Trek fallacy, the fallacy of assuming that when emotion is present, reason is not, and when reason is present emotion is not. Notice, for example, the Professor's rational argument for believing Lucy in the Lion, the Witch and the Wardrobe. Who would care at all about reason if we didn't have a passion for the truth?
