St. Francis de Sales answered your points already in the above chapter.
Yes. I am sure he did, but sometimes having things formed as questions helps us think better.
I know for myself I get lost in all the words and lose some understanding. People do not all learn the same way. For me to really understand something, I have to have a conversation. I have to talk it out, ask questions, and reform my thoughts. I can't be the only one who learns this way.
