One of them is the world-famous author of "The Name of the Rose", a renowned scientist, philosopher, who calls himself an unbeliever, the second is a high-ranking clergyman and respected scholar of the New Testament. Dialogue awakens their thoughts and brings true intellectual pleasure. They argue about the main issues of modern life, not for a moment forgetting that they are separated by the gulf between faith and unbelief, but also without losing respect for someone else’s point of view. This highly intellectual and highly spiritual exchange of views will undoubtedly touch sensitive chords in the souls of both believers and non-believers.* * *Original title: Carlo Maria Martini e Umberto EcoIn cosa crede chi non crede?
