Adaptability

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.
