That, in my opinion, was the most diabolical aspect of those old-time big brains: They would tell their owners, in effect, 'Here is a crazy thing we could actually do, probably, but we would never do it, of course. It's just fun to think about.' And then, as though in trances, the people would really do it--have slaves fight each other to death in the Colosseum, or burn people alive in the public square for holding opinions which were locally unpopular, or build factories whose only purpose was to kill people in industrial quantities, or to blow up whole cities, and on and on.
