In 1925 the philosopher GE Moore wrote a Defence of Common Sense which argued against philosophical idealism, on the grounds that it seemed to deny a set of propositions that he claimed were indisputably true. His colleague Ludwig Wittgenstein wrote a detailed response to Moore's paper, and its influence extended into the work of contemporaries like Susan Stebbing. How do we understand common sense now? What role does common sense play in politics? Matthew Sweet's guests are the philosopher Dr Rachael Wiseman, the politician Ann Widdecombe, the historian of emotion Dr Tiffany Watt Smith and the journalist and scholar of post colonial culture Dr Sarah Jilani.
