The book challenges the accepted monotheistic vision of the afterlife. The Cathars did not believe in hell a belief which leads to unexpected consequences. The conclusions are life changing.
Long crusades and the Inquisition took care of Catharism because the concept of "no hell" unlocks the structure of monotheism and is the harbinger of an intellectual revolution impacting on Judaism, Christianity and Islam.
"Indulgence" will change the way we think in a Western World heavily influenced by monotheism.
Humanism, atheism, and antitheism among other philosophical systems help to cope with life and offer different views of the world. The writer Albert Camus in some of his well known books reflects on life without the god-idea.
He wrote the beginning of "La Peste" in le Chambon sur Lignon a village in the Cevennes known also for saving thousand of Jewish children during the 2nd World War.
Le Chambon had been at the heart of the turmoil during the religious wars and was a centre for the Resistance during the 2nd World War.
