Reith Lectures #2: Is there such a thing as evil?

In a career spanning over 30 years, Dr. Adshead has heard many of her patients ask: "I have done evil things, but does that mean I am evil? In her second BBC Reith Lecture, Adshead asks if there is such a thing as evil. She argues we all have capacity for 'evil' and says we need to find ways to cultivate societal and individual 'goodness.' *The Reith Lectures originally aired on BBC Radio 4.
