Augustine discerns an inner connection between imperium and pornography.
Imperium is the political form of the libido dominandi. Pornography is the sexual form of the same libido.
Both imperium and porn reduce human persons to bodies to be manipulated for the manipulator’s pleasure.
Decadence is built into imperium.
