The discussion of Providence and Fate allows Philosophy to slightly update the argument she has already made, that everyone always gets their due because of God. Nothing is evil in Providence, but in Fate, God sometimes has to introduce evil to keep things in balance. Here, Philosophy makes something of a power move: since God is superior to humans, humans sometimes will fall short of understanding what He is trying to do. But because they are capable of knowing
that he exists and has this power, they should trust in His Providence. This is not a reason to reject reason and choose blind faith, but rather only a reminder that reason—although infallible about what it
does cover—ultimately has its limits.
