Richard Holloway's mix of entertaining, challenging and thought provoking chat and music. Today Richard is in conversation with a woman who's been at the heart of public debate on important social and moral issues for over forty years, Mary Warnock. A member of the House of Lords, Baroness Warnock is a philosopher, a teacher and an author of a number of challenging books, but she's probably best known for chairing two influential committees, one of Special Educational Needs and the other on Human Fertilisation and Embryology. Now in her 80s, Mary reflects on her life and work.
