What was C.S. Lewis’s wartime BBC broadcast series first called in 1941?

C.S. Lewis’s wartime BBC broadcast series was first called Right and Wrong: A Clue to the Meaning of the Universe.

Lewis delivered a series of radio talks for the BBC during the Second World War. The first set was broadcast in 1941 under the title Right and Wrong: A Clue to the Meaning of the Universe. Later groups of talks were broadcast under different titles, including Christian Behaviour and Beyond Personality.

The talks were eventually revised and collected as Mere Christianity, one of Lewis’s best-known works of Christian apologetics. Rather than defending a single denomination, the book presents what Lewis described as shared or “mere” Christian beliefs. The title therefore belongs to the later collected publication, not to the original first broadcast series.

This publication history causes frequent confusion because readers often use Mere Christianity as though it were the original radio title. Lewis’s broadcasts became popular partly because they translated theological arguments into direct, conversational language for a broad wartime audience.
