I think an interesting topic would be how Steve uses his knowledge of different belief systems to analyze his life and to make meaning out of events that happens to him and to others.
For example, he talks about how religions, objective reality, and subjective reality (and to an extent, world and psychic experiences), can act as a lens in which to view reality. I'd be interested to hear how (and when) he chooses which specific lens to use. And if he wanted to go in greater detail, how he then uses those lenses to analyze the situation(s). It'd sure make for some interesting discussion!
