Philosophy’s song about knowledge references the structure of her dialogue with Boethius: he has forgotten the truths of her wisdom due to his misery and preoccupation with material things, but he still “holds the sum” of truth somewhere deep in his mind, and learns to recover it over the course of their conversation. In fact, her argument—that people somehow have “the sum” of truth inscribed somewhere in their souls, but forget it through the bodies until they are able to relearn it through philosophy—comes straight from Plato’s theory of knowledge in the dialogue
Meno, and is essentially a statement of philosophy's purpose for its disciples.
