In this week’s books podcast, I talk to the former head honcho of the National Gallery and British Museum, Neil MacGregor, about his new book Living With The Gods: On Beliefs and Peoples.

What do religions have in common? How do you represent icon-averse creeds through physical objects? Why should there be an evolutionary advantage in engaging with the intangible or imaginary? And what does the history of religion tell us about the common threads of humanity?
