Is consciousness everywhere? Human consciousness - our subjective experience - remains a mystery. How is it that we can smell coffee and feel the touch of a flower? How does the brain produce consciousness? Well, one of the world’s top philosophers, David Chalmers, has a suggestion. Perhaps consciousness exists everywhere, in some form; perhaps it exists in every subatomic particle – the particles that make up not just humans, but tables and chairs. It sounds completely wacky? But Professor Chalmers explains why it’s a theory worth taking seriously. Presenter David Edmonds Producer Ben Cooper (Image: Glittering Particles Credit: Shutterstock)
