The author wrote a piece called "What Our Children Should Learn about 9/11." In that piece, the author made just four simple points. These include: (1) children should know the facts; (2) once they had a grounding in the facts, the children should not abjure moral judgment; (3) children should learn to make both analytical and moral distinctions; and (4) children must learn to live with uncertainty, and specifically to understand the difference between living in fear and living with fear. Ten years have passed 9/11 and more than nine years have passed since he wrote that piece. He would not change a word had he to write it over again, but he has learned plenty over the past decade. Without repeating that little essay, the author wants to go back over each of the four points, especially the first one, in order to reflect on what the past decade has wrought. In this article he focuses on the first point: the importance of basic facts. (Contains 8 online resources.)
