One of the highlights of the Edinburgh International Book Festival was hearing Yanis Varoufakis in conversation with Shami Chakrabarti – two sane voices in a world gone mad. The former Greek Finance Minister’s most recent book is Adults in the Room. Near the end of his session, in response to a question from the audience, he paraphrased Gramsci, saying we have to be pessimistic with the mind but optimistic in the heart. Sound advice!
