Because this is something I’ve been thinking about lately whenever I see the news: 

“‘HUMANS NEED FANTASY TO BE HUMAN. TO BE THE PLACE WHERE THE FALLING ANGEL MEETS THE RISING APE.’ 

“‘Tooth fairies? [Santa Claus]? Little—’ 

“‘YES. AS PRACTICE. YOU HAVE TO START OUT LEARNING TO BELIEVE THE LITTLE LIES.’ 

“‘So we can believe the big ones?’ 

“‘YES. JUSTICE. MERCY. DUTY. THAT SORT OF THING.’”
