The Hanseatic League — the medieval trading network that made these Dutch river cities wealthy — had no army, no police, no enforcement of any kind. It ran entirely on reputation. A merchant who cheated in one city couldn't trade in another. The whole network held together because everyone understood their good name was worth more than any single deal. Walking east of Doesburg last summer, I passed honor-system egg boxes tied to trees beside the path. Same principle, smaller scale. New in The Curious Wanderer.
