The author asks his old professor about the purpose of college. She says,
I wonder about how one becomes thoughtful. Can thoughtfulness be taught? I think so - I hope so. Hence, I believe questions are more important than answers. Questions invite thoughtfulness; answers deny it.
Did I learn thoughtfulness in school -- any of the schools from kindergarten to graduate school? Or did I learn thoughtfulness growing up in a family that asked questions. For example, when my older siblings and I were growing up, my father would ask each of us at mealtime: What did you do today for the benefit of humanity?
