The title of this episode is Scholasticism
One of the most important questions faced by philosophers & theologians throughout the centuries has been the interplay between Faith & Reason. Are they enemies or allies? Is the Christian faith reasonable, or a blind leap into an irrational darkness? A major advance in answering this came with the emergence of a group of medieval theologians known as the Scholastics. Chief among them were Anselm of Canterbury in the 11th C & Thomas Aquinas in the 13th.
In his novel Pillars of the Earth, author Ken Follett spins an intriguing tale of the construction of a cathedral in England. While the cathedral & town are fictional, Follett does a masterful job of capturing the mindset and vision of medieval architecture.
