“That's for the best. Otherwise they might realize they're in prison. It can't be helped. You women are used to harems and prisons. A person can spend his whole life between four walls. If he doesn't think or feel that he's a prisoner, then he's not a prisoner. But then there are people for whom the whole planet is a prison, who see the infinite expanse of the universe, the millions of stars and galaxies that remain forever inaccessible to them. And that awareness makes them the greatest prisoners of time and space.”
