What a bad opinion you have of him; I thought you would apologize to him, not confirm it... (I'm afraid I can't answer your question because I don't have direct evidence; I haven't spoken to him personally to confirm this. Nevertheless, his biography shows that at some point in his life, he had a positive reaction to his sister's plans for monastic life. He was a member of the so-called Jansenists, who downplayed the role of man in some matters and said that God's role in his life was particularly great. He openly argued with the Jesuits, saying that they were not demanding enough in terms of human morality, that they attracted people to the church but did not care about their religiosity, although they should. If he was insincere in all of this, if it was all for show, then... This is not only extremely offensive to this person, but it is also at least implausible.)
