Between people like us, this is somewhere between a failure to allow for the looseness of speech and the kind of interesting contradiction we like because it's evidence-rich, and probably closer to the former. To a religious person, this is just a pretty combative trap. There are a large number of such traps you can run on religious people, and they very rarely accomplish anything, because these almost always aren't the kind of people who take logic and rationality seriously enough to change their beliefs due to contradictions, but they normally are the kind of people who fail to Keep Their Identity Small and hence become personally offended when you try to bring up contradictions. Asking the philosophers he's going to see trap questions like this will just annoy them (they'll probably even see the "looseness of speech" explanation for this one), provoke useless stock answers, and waste the potential of the conversations.
Thank you for your comment: you have shown me that I failed to make my intention plain. I have edited my original comment in the hopes of remedying this; please let me know if I have succeeded by up-voting, or if I have failed by down-voting and, if you are again willing to help me, offering me further critique :) My sincere thanks, again.
I am about to graduate from one of the only universities in the world that has a high concentration of high-caliber analytic philosophers who are theists. (Specifically, the University of Notre Dame, IN) So as not to miss this once-in-a-lifetime opportunity, I have sent out emails asking many of them if they would like to meet and discuss their theism with me. Several of them have responded already in the affirmative; fingers crossed for the rest. I'm really looking forward to this because these people are really smart, and have spent a lot of time thinking about this, so I expect them to have interesting and insightful things to say.
Do you have suggestions for questions I could ask them? My main question will of course be "Why do you believe in God?" and variants thereof, but it would be nice if I could say e.g. "How do you avoid the problem of X which is a major argument against theism?"
Questions I've already thought of:
1-Why do you believe in God?
2-What are the main arguments in favor of theism, in your opinion?
3-What about the problem of evil? What about objective morality: how do you make sense of it, and if you don't, then how do you justify God?
4-What about divine hiddenness? Why doesn't God make himself more easily known to us? For example, he could regularly send angels to deliver philosophical proofs on stone tablets to doubters.
5-How do you explain God's necessary existence? What about the "problem of many Gods," i.e. why can't people say the same thing about a slightly different version of God?
6-In what sense is God the fundamental entity, the uncaused cause, etc.? How do you square this with God's seeming complexity? (he is intelligent, after all) If minds are in fact simple, then how is that supposed to work?
I welcome more articulate reformulations of the above, as well as completely new ideas.
