Thanks acs - I will look for the albert schweitzer biography. That sounds like a good one that will lead to some interesting discussions. I think books with the "reverence for all life" principle, and other core principles that I don't really have a grasp on, are the sort of thing i'm looking for. Or maybe even philosophy. I guess I don't really know exactly what i'm looking for, but i do know i felt pretty stupid trying to quickly explain god and faith to DS before he got it from preschool. blush
