Published posthumously in 1964 just a year after C.S. Lewis’s death, “The Discarded Image: An Introduction to Medieval and Renaissance Literature” is a wonderful book even if its title is far from accurate. Anyone who goes into the book expecting an introduction to literature will be sorely disappointed. You won’t learn what the “Canterbury Tales” and “Sir Gawain and the Green Knight” are about; ironically for an “introduction,” Lewis mostly assumes you’re at least passingly familiar with the so-called Great Books from roughly 500-1500 A.D. Instead, he builds a comprehensive, synthetic medieval “model” of the universe that will help you inhabit the medieval imagination – from assumptions about cosmology to science, history, the human body, psychology, the liberal arts, and more. To do this, he doesn’t go to scientific texts of the time but gleans everything he can from imaginative literature.
What will make the book difficult for contemporary readers is that much of Lewis’s material comes from a lifetime immersion in the literature of the period. The usual suspects – Augustine, Aquinas, Lucan, Apuleius, Boethius, etc. – all make appearances. But just as many insights are drawn from authors that aren’t read by anyone but classicists: Statius, Claudian, Chalcidius, and Pseudo-Dionysus. It is still very much worth the effort. Just know that you’ll have to hand yourself over to Lewis’s literary interpretations and inferences, which isn’t a big ask when the author in question was a medievalist himself, as Lewis was.
To unpack the medieval mind, Lewis suggests that we remember two things: the intense bookishness of their intellectual life and their extraordinary talent for categorization, organization, and classification. There is no contradiction a medieval scholar could not reconcile if they wished to. Their intense bookishness led them to treat their ancient forebears with a bit too much credulity – surely one of the reasons why Aristotle remained the go-to author for many subjects even two millennia after his death. Lewis argues that the same credulity also allowed for a seamless blending of pagan and Christian which we recognize as uniquely medieval.
The tidy world-building connected every aspect of their hierarchical world in a Great Chain of Being, with everything reflecting the divine unity of God himself, redounding down to the nine choirs of angels and eventually humans and animals. Each have their place: from the Earth to the final sphere, the Primum Mobile, which God alone can touch and imparts all motion to the spheres below it. The medieval model postulates four substances – cold, hot, moist, and dry – the combinations of which gave us words that we still use to describe human dispositions like sanguine, choleric, phlegmatic, and melancholic.
In an epilogue that is a literary and cultural parallel to Thomas Kuhn’s “The Structure of Scientific Revolutions,” Lewis writes that the medieval image he describes has since been discarded for a more modern one, and that the modern one will eventually be displaced as well. In much the same way that Einstein’s idea of gravity replaced Newton’s in the light of new evidence, the prevailing ideas we use to make sense of our world slowly change with cultural norms and values.
The contemporary world, even the worldview of contemporary religious people, is highly secularized. Freedom of conscience and a wall of separation between church and state are mostly taken for granted, but these would have been wildly foreign concepts to most people during the period Lewis discusses. While the greatest medieval and Renaissance literature will always appeal to our imaginations, “The Discarded Image” is a short book that goes a very long way in recreating the complex intellectual architecture that shaped that literature. It thereby bridges a gap to an earlier time that can seem so utterly different from our own. Read it not as an introduction but as a companion piece to everyone from Cicero to Boccaccio and it’s sure to constantly reveal new facets and nuances to the literature we already love, but Lewis can help us appreciate anew.
