Why are we conscious?
It turns out that much of what we do – much of our behaviour – can be conducted at an unconscious level. That raises a profound question. What is the point of consciousness?

And we ask a philosopher whether science can ever unravel the deep mysteries of consciousness. The programme is guaranteed to hurt your brain.Presenter and producer: David Edmonds Editor: Richard Knight(Photo: / Credit: Doorway to another world - stock photo. Getty Images)
