Dante’s Purgatorio has always seemed to me to fly under the radar. Inferno draws most people’s attention, and Paradiso, while much less well known in its details, is generally understood to be the final objective of the work. But what is the point of purgatory, after all? Just a way station between the horrible beginning and the heavenly end?
But Purgatorio contains much of what is “political” in Dante’s thought. Purgatory is in some ways a Christian metaphor for this world. While Inferno houses the souls of those who have done unspeakable things, Purgatorio is the place for those with evil in their hearts, impure motives, sinful dispositions that still separate them from paradise. Each of the seven “terraces” concerns a different vice, with virtuous counterexamples. One of the most memorable scenes in the Terrace of Pride is the building of the Tower of Babel, a central metaphor for political pride throughout the ages from Dante to today (see, for example, the magnificent final essay by Michael Oakeshott in this volume).
Here is a new book that focuses on Dante’s political thought in the Purgatorio, with a special emphasis on the role of law: Dante’s Philosophical Life: Politics and Wisdom in “Purgatorio” (Pennsylvania Press) by Paul Stern.
When political theorists teach the history of political philosophy, they typically skip from the ancient Greeks and Cicero to Augustine in the fifth century and Thomas Aquinas in the thirteenth, and then on to the origins of modernity with Machiavelli and beyond. Paul Stern aims to change this settled narrative and makes a powerful case for treating Dante Alighieri, arguably the greatest poet of medieval Christendom, as a political philosopher of the first rank.
In Dante’s Philosophical Life, Stern argues that Purgatorio’s depiction of the ascent to Earthly Paradise, that is, the summit of Mount Purgatory, was intended to give instruction on how to live the philosophic life, understood in its classical form as “love of wisdom.” As an object of love, however, wisdom must be sought by the human soul, rather than possessed. But before the search can be undertaken, the soul needs to consider from where it begins: its nature and its good. In Stern’s interpretation of Purgatorio, Dante’s intense concern for political life follows from this need, for it is law that supplies the notions of good that shape the soul’s understanding and it is law, especially its limits, that provides the most evident display of the soul’s enduring hopes.
According to Stern, Dante places inquiry regarding human nature and its good at the heart of philosophic investigation, thereby rehabilitating the highest form of reasoned judgment or prudence. Philosophy thus understood is neither a body of doctrines easily situated in a Christian framework nor a set of intellectual tools best used for predetermined theological ends, but a way of life. Stern’s claim that Dante was arguing for prudence against dogmatisms of every kind addresses a question of contemporary concern: whether reason can guide a life.
