Orthodox Judaism is a thicket of detailed injunctions, Biblical commandments elaborated during centuries of prohibited proselytizing, functioning to limit interaction with outsiders. At the opposite extreme, Islam, still the most rapidly expanding of faiths, demands little immediate knowledge from those who would convert.

The human species thinks in metaphors and learns through stories.
