Commentary Par XVIII 3

Few commentators point out the obvious (but see at least Carroll [DDP Carroll.Par.XVIII.1-18]): The third verse reflects Cacciaguida's promise ([Par XVII 43-45]) of an eventual harmonious resolution of the problems inherent in Dante's exile.  The protagonist is now capable of a larger and wider view of the impending events in his life, knowing that they are a part of the divine plan, one that includes his writing this text and that corroborates the rightness of his political decisions in the greater scheme of things.  Unlike Cacciaguida, however, he is not yet capable of seeing essences without their contingent trappings.
