Famous quotes containing the words primitive and/or pit:
“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)
“Treading the soil of the moon, palpating its pebbles, tasting the panic and splendor of the event, feeling in the pit of one’s stomach the separation from terra ... these form the most romantic sensation an explorer has ever known ... this is the only thing I can say about the matter. The utilitarian results do not interest me.”
—Vladimir Nabokov (1899–1977)
