During World War II, when Britain was fighting against the evils of Nazism, the director of religious programming at the BBC, asked C.S. Lewis to give some talks about faith. The Oxford professor reluctantly agreed, and on August 6, 1941, at 7:45 in the evening he gave his first broadcast.

This first broadcast on right and wrong would go on to e the most read radio series in British broadcasting history, and was used as the first chapter of Mere Christianity, one of the most influential Christian books of the twentieth century.

All but one of the original broadcast have been lost, but CSLewisDoodle has produced this animated recreation which highlights Lewis’s argument about how the natural law provides a clue to the meaning of the universe.
