Since Adam was the first human being, his experiences wholly unique and also establishing conditions for the rest of humanity, Dante’s insatiable curiosity is understandable (and humorously characteristic of Dante). Adam explains that when he and Eve were cast out of the Garden of Eden, it wasn’t because their appetite was sinful in itself, but because they transgressed God’s boundaries. Adam also gestures to the idea that language evolves over time. This point was of special interest to Dante the scholar, who wrote about the importance of vernacular speech (local native languages) in his
De vulgari eloquentia.
