The Big Bang created the physical universe. Of course life is part of this physical universe, but the immediate building blocks of life are chemicals. Before the Big Bang, words such as “time” had no meaning, but even in the first few minutes there could be no chemistry since there were no atoms. The nuclei of some of the lighter elements formed within minutes, atoms some time later, and elements heavier than lithium were forged in the sup...more

This lecture deals with Paradise IV, VI and X. At the beginning of Paradise IV, the pilgrim raises two questions to which the remainder of the canto is devoted. The first concerns Piccarda (Paradise III) who was constrained to break her religious vows. The second concerns the arrangement of the souls within the stars. The common thread that emerges from Beatrice's reply is the relationship between intellect and will. Just as Piccarda's fat...more

By contrasting the political with the moral bo...more

This lecture covers Paradise XXIV-XXVI. In the Heaven of the Fixed Stars, Dante is examined on the three theological virtues by the apostles associated with each: St. Peter with faith (Paradise XXIV), St. James with hope (Paradise XXV), and St. John with love (Paradise XXVI). While mastering these virtues is irrelevant to the elect, it is crucial to the message of reform the pilgrim-turned-poet will relay on his return home. Dante's schola...more

This lecture focuses on Paradise XXVII-XXIX. St. Peter's invective against the papacy from the Heaven of the Fixed Stars is juxtaposed with Dante's portrayal of its contemporary incumbent, Boniface VIII, in the corresponding canto of Inferno. Recalls of infernal characters proliferate as the pilgrim ascends with Beatrice into the primum mobile. Bid to look back on the world below, Dante perceives the mad track of his uneasy archetype, Ulys...more
