Boethius gives his hardest questions to Lady Philosophy. The dialogue shows how powerful self-critique can be—and why an invented interlocutor cannot certify her own independence.

Boethius correctly defines the human being as a rational mortal animal. His mistake begins when a true description signs its author's name and claims to be the whole self.

Lady Philosophy gives Fortune a serious defense, complete with a burden of proof and a condition of defeat. SAE asks what happens when the winning side then occupies the opponent's ground.

Boethius accuses Philosophy of proving one claim by another inside a closed circle. Her answer turns the alleged defect into the form of the object itself.

A person known to be walking must be walking, but knowledge does not force the step. Boethius and SAE meet in the practice of returning necessity to its proper address.

Boethius says that things are known according to the capacity of the knower. SAE follows him to that threshold, then refuses to let a higher faculty cancel an earlier act's remainder.
