The heart is the most symbolic organ of the human body. Throughout history it has been seen as the site of our emotions, the very centre of our being. But modern medicine has come to see the heart as just apump; a brilliant pump, but nothing more. And we see ourselves as ruled by our heads and not our hearts.
In this documentary, filmmaker David Malone asks whether we are right to take this view. He explores the heart's conflicting histories as an emotional symbol and a physical organ, and investigates what the latest science is learning about its structures, its capacities and its role. In the age-old battle of hearts and minds, will these new discoveries alter the balance and allow the heart to reclaim something of its traditional place at the centre of our humanity?
