Science and a "spiritual dimension"?

The BBC’s online magazine asks “What do you get if you divide science by God?”, which is possibly one of the daftest questions imaginable. In an article about “the meaning of physics”, Mark Vernon reports:

The Templeton Prize, awarded for contributions to "affirming life's spiritual dimension", has been won by French physicist Bernard d'Espagnat, who has worked on quantum physics with some of the most famous names in modern science.

What the heck is a “spiritual dimension”? What does “spiritual” mean? Blowed if I know. Why not add a comment on the BBC website?

Yes, I know. I’m just a grumpy old sceptic.
