One of the great pleasures of reading and re-reading is encountering conceptual connections between authors and works that you may have never considered in common. I had one of these experiences recently while reading a short book about Dante. While working through the author's discussion of Monarchia and its relation to the Purgatorio, I found myself thinking that in some respects Dante's dualistic political philosophy anticipated important elements in Kant's short monograph Groundwork of the Metaphysics of Morals and his essays "What Is Enlightenment?", "The Idea for a Universal History with a Cosmopolitan Intent," and "Toward Perpetual Peace."
