The atheist David Attenborough considered that:
Great minds can express themselves in music. Bach can communicate not only to his own people but across the centuries. Bach is about mercy and about love of humanity and a vision of the infinite—what that means I have no idea—but I can’t think of any other words to use to explain many a Bach cantata.
This was followed by an astute observation from Russell Grigg:
Very interesting, especially in view of the fact that Bach once said, ‘Music’s only purpose should be the glory of God and the recreation of the human spirit.’
