Final answer:
Dante discusses the immortality of the soul and the knowledge of future events with the heretics in Canto 10 of Inferno, rather than their specific heretical beliefs.
Step-by-step explanation:
In Canto 10 of Dante's Inferno, Dante engages in conversation with the heretics, but the dialogue does not focus on heresy in the context of religious beliefs. Instead, Dante addresses two distinct topics during his discussions with the heretics. First, he explores the nature of the soul's immortality, contemplating its existence after physical death. Second, Dante investigates the knowledge of future events, to what extent the da_mned are aware of the earthly future. These are philosophical discussions that touch upon the heretics' beliefs, but they do not delve into the specifics of their heretical views against Christian doctrine.
