One of the people who has greatly influenced my thinking about conversation is the Oxford scholar and thinker Theodore Zeldin.
He has published a new book The Hidden Pleasures of Life: A New Way of Remembering the Past and Imagining the Future which has just landed on my door mat that I am greatly looking forward to read.
He is a fascinating gentleman. Yo can hear him talk about his new book in this Radio 3 interview.
He says he is not a teacher - he does not tell people what to do but "this is what I have found - what does it excite in you?".
Take a look at his Oxford Muse: "A Foundation to stimulate courage and invention in personal, professional and cultural life.". In particular, his Conversation Dinners. He really is an interesting thinker.
