Sometimes Alton Darwin would talk to me about the planet he was on before he was transported in a steel box to Athena. 'Drugs were food,' he said. 'I was in the food business. Just because people on one planet eat a certain kind of food they're hungry for, that makes them feel better after they eat it, that doesn't mean people on other planets shouldn't eat something else. On some planets I'm sure there are people who eat stones, and then feel wonderful for a little while afterwords. Then it's time to eat stones again.
