A. C. Grayling is one of the world’s most widely read and celebrated philosophers. This year, the long-time Sydney Writers’ Festival favourite transcended the barriers of distance and the disruption of the global pandemic to join us from the UK to discuss his latest work, The Frontiers of Knowledge, with host of ABC Radio’s Conversations, Richard Fidler. In his inimitable style, this exploration of the paradox of knowledge – that the more we know, the greater our ignorance – reflects on the importance of education and culture to connect us to one another, to new ideas and to different branches of knowledge that can help us understand who we are in the world.
