We assume that below a mental 'surface' of conscious awareness lies a deep and complex set of inner beliefs, values and desires that govern our thoughts, ideas and actions, and that to know this depth is to know ourselves.

The pair discuss the latest research in psychology and neuroscience detailed in Professor Chater's book The Mind is Flat, where Professor Chater argues that rather than being the plaything of unconscious currents, the brain generates behaviours in the moment based entirely on our past experiences and environment.

The brain, Professor Chater contends, is a ceaseless and creative improviser. Read an extract from the book at here.
