Génie du christianisme, genius of convents?

In Génie du christianisme, Chateaubriand tries to promote monastic orders, attacked by Enlightenment philosophers. Beside their charitable actions, he praises the enchanting and poetic side of these religious lives, and he attempts to prove the historical necessity of the shelter offered by convents to melancholic souls. But flaws in the argument appear which are developed in fictions of early nineteenth century, by emphasizing inner dramas that take place in convents.
