The thing about our being so adaptable. We could be born into any world, no matter how fantastic, and would take it for granted. This might explain the persistence of culture as nurture, the staying power of so many elaborate beliefs. Born and reared by them we know no better, yet they become us, they bring us full circle, unless we happen to witness the certain amount of ruin they may cause, as happens more and more today on an Earth with fewer and fewer shadows.
