British academic lawyer Professor Sir Ian Kennedy explores the concepts of modern medicine in the fourth Reith lecture from his series entitled 'Unmasking Medicine'.

In this lecture entitled 'If I Were You, Mrs B', Professor Kennedy contemplates the ethical medical issues that doctors have to make and debates whether they are trained enough to decide such complex issues. He argues that doctors are making principled and moral decisions rather than just technically medical ones and with this blurring of boundaries comes consequences. He explores some examples to argue his point that doctors need to be trained in the humanities and not just the sciences.
