"Our ancestors - well, as you know, came from a very warlike background. They wanted to put down everything that seemed to them related to it and make sure that their descendants couldn't go right back to making war on each other. They built a ship. It has a - machine, a very complicated machine, I can hardly imagine how complicated, which - controls the ship, grows crops and manufactures medicines and controls the weather, in response to prayers. And the settlers... I guess thought that it would be easier, for everyone to get along, if they all believed in a god commanding them to do so. - if we don't all show up, representatives from every group of people on our world, to sing the Gloria every year, it'll start attacking the planet rather than let us dig into whatever conflict would prevent us from observing it together."
