I refer to the restaurant—and here I am guessing. But imagine the confidence, the civility required for people first to come to a strange table, possibly in a shady courtyard in Loyang, and to sit down with others whom they do not know, or only remotely know, without fear of being attacked or stabbed. An unknown chef then serves food, which they eat without fear that it may be poisoned. It’s a revolution! The restaurant opens a new era in social relationships. In those remarkable circumstances, one not only eats, one converses. And from conversation new ideas are born.
