Neurobiologist and lecturer of Physiology at the University of Cambridge Colin Blakemore considers mental illness and morality in his sixth and final Reith lecture from his series 'Mechanics of the Mind'. He questions why society attempts to regulate the behaviour of its members and tries to order them into normal and abnormal.

In this lecture entitled 'Madness and Morality', Professor Colin Blakemore expands on the many ways cerebral irregularities have been treated throughout history; invasive psychosurgery and electro-therapy were the precursors to modern day medicines and psychiatry.
