This is the 2010 Richard Dimbleby Lecture, where much-loved fantasy writer, Terry Pratchett, argues the case for assisted dying as a human right in specific circumstances. Since being diagnosed in 2007 with early onset Alzheimer’s disease, he’s been the public face of the movement. While he gives the introduction, the lecture is given by actor Tony Robinson, since his disease makes it impossible to read the lecture. Writing it is another matter. Sir Terry makes a warm, witty, cogent, utterly unsentimental case for assisted dying, which manages at the same time to be immensely moving.
