Paul attended his first college class today. Afterward, he said to me, "That was the best class I was ever in." He told me how hard the students were thinking, how easily they shared their ideas, how the teacher let the students guide the discussion, how much he learned, how much he could tell they were learning.

I told him that this is what people hunger for: this kind of intellectual engagement that is so intense that it becomes an emotional bond.

"Yes," he said.
