This book is a sweeping intellectual biography and cultural history that brings to life one of the most brilliant yet misunderstood thinkers of the Middle Ages. Born in an obscure Scottish village and rising to the heights of Oxford and Paris, John Duns Scotus reshaped Western philosophy with ideas so bold that they still animate debates in metaphysics, ethics, and theology today.

Set against the backdrop of a Europe in upheaval-where kings battled popes, universities exploded with new learning, and the mendicant orders reinvented religious life-this book traces the dramatic rise of the Franciscan intellectual tradition and the extraordinary mind that would transform it. From the mystical vision of Bonaventure to the radical voluntarism of Peter John Olivi, the Franciscan world was a crucible of spiritual passion and philosophical daring. Scotus inherited this world and remade it, forging doctrines of freedom, individuality, and divine love that would echo through the centuries.

Drawing on the latest scholarship and the richness of medieval sources, this book offers a vivid portrait of Scotus's life-from his uncertain beginnings in Duns to his meteoric academic career, his exile during the Parisian political crisis, and his final years in Cologne. It also follows his ideas far beyond his lifetime, showing how his thought shaped the Franciscan school, influenced modern philosophers from Kant to contemporary analytic metaphysicians, and ultimately contributed to his beatification in 1993.
