For those who love to learn and love the flow of learning, a fascinating first entry to a trilogy — read the whole thing.
It often takes weeks of hard labor together to reach such a point. One gets a very hard text and says nonsense about it at first. The talkative one in the group, how often I have played that role, says his piece and re-says it until he learns to be quiet. The silent student in the corner is at last provoked to say something and we discover that the one who has said nothing has something to say. Both are tempered. The louder one is mellowed to leadership, the silent one grows deeper and wise.
I remember many such moments from high school through college (why should it stop then?) — treasures of a lifetime.
