Here Dr William Large from the University of Gloucestershire talks about one book, Martin Heidegger's magnum opus, Being and Time. Here we try to get to the bottom of this endlessly fascinating book, looking at some of the key moments from the text such as death, anxiety, authenticity and how we are beings in the world. Will is the author of, among other things Heidegger's Being and Time: A Philosophical Guide. You can find out more about Will here.
