Funny thing about those Middle Ages, said Joseph. They just keep coming back. Mortals keep thinking they're in Modern Times, you know, they get all this neat technology and pass all these humanitarian laws, and then something happens: there's an economic crisis, or science makes some discovery people can't deal with. And boom, people go right back to burning Jews and selling pieces of the true Cross. Don't you ever make the mistake of thinking that mortals want to live in a golden age. They hate thinking.
