A Man Called Charles Williams, A Thing Called Coinherence, Part 1

Sayers had a friend named Charles Williams, who had a theory
called Coinherence. This man and his idea figured largely in her
later work. In this episode, we learn a bit about Williams and a
lot about what Coinherence is, how it works, and, truth be told,
how it can help us in our hour of need. On the surface, it's one
of those general, pleasant ideas that we all assume is true. But
Williams gave it a name and considered it one of the most
powerful forces in creation. And Sayers agreed with him.
