Crazy Paris Art Work

An exhibition in Paris at the Bibliotheque Nationale has caused a bit of a stir, with the work on an insane man's ramblings that were carved into his floorboards.
Plancher de Jeannot (Jeannot's Floorboards) is the bedroom floor of a schizophrenic French farmer, carved with 80 lines of unpunctuated text. It mentions religions, brain controlling machines, Hitler and the Pope.
People are saying that the work should not be on public display and is simply the work of madness. But isn't it "madness" that inspires so much great art throughout art history?. Jeannot's bedroom floor is an extreme case, as he was truly mad, but the measure of one's sanity can hard determine the value of one's art.
Paris revolts over morbid artwork
Some of the text on the floorboards.. "Religion has invented machines for commanding the brain of people and animals and with an invention for seeing our vision through the retina uses us to do ill.. the church after using Hitler to kill the Jews wanted to invent a trial to take power.. we Jean Paule are innocent we have neither killed nor destroyed nor hurt others it's religion that uses electronic machines to command the brain."
