“In some ways being a parent is like being an anthropologist who is studying a primitive and isolated tribe by living with them.... To understand the beauty of child development, we must shed some of our socialization as adults and learn how to communicate with children on their own terms, just as an anthropologist must learn how to communicate with that primitive tribe.”
—Lawrence Kutner (20th century)
“I saw Eternity the other night,
Like a great ring of pure and endless light,”
—Henry Vaughan (1622–1695)
