Umberto Eco is known as the author of six classic novels, but he considers his scientific work more significant. He is an outstanding semiotician, medievalist, cultural scholar, and mass media scholar, as well as an honorary professor at several universities. In this book, he introduces readers to the works of great thinkers of the Middle Ages such as Thomas Aquinas, Saint Bonaventure, Duns Scotus, and William of Ockham, who studied problems of aesthetics. Questions about beauty and its nature—whether there exists objective beauty independent of the viewer—help better understand the sense of the beautiful and appreciate the diverse manifestations of beauty in the world.
