Eugene Volokh has some interesting posts asking readers, both religious, and irreligious, to answer some challenging questions (the religious to explain their belief in miracles, and the irreligious to explain their secular moral axioms).
As Eugene says:
I’m not expecting or intending to convert anyone in either direction — just to enlighten people about others’ world views, by asking each side to explain themselves about something that I think the other side really is curious about.
It’s a cool idea. Let’s see how well it works out.
