Dante’s "revolution" refers to the profound literary, linguistic, and philosophical upheaval sparked by the medieval Italian poet Dante Alighieri through his masterpiece, The Divine Comedy. Writing between 1308 and 1321, Dante shattered a thousand years of medieval European dogma, shifting the focus of human nature from inherently sinful to optimistically driven by individual free will and love. Scholars like Professor Jiang often describe his impact as a "quiet revolution" because it provided the intellectual blueprint for the Renaissance, the Scientific Revolution, and modern secular humanism.
