Philosophy for Life (and other sentences). Some interesting thoughts about teaching philosophy to prisoners … how to do so and whether it is after all something worth doing. “I got onto the idea of focusing on what you can control rather than what you can’t. I told the story of Rhonda Cornum, how she had used Stoic techniques to cope with being a prisoner-of-war. ‘When you’re a prisoner, your guards control everything about your life, everything external anyway, except your thoughts and beliefs.’ That got their attention. Stoicism, after all, is very much a philosophy of finding inner freedom in external imprisonment – that’s why it’s inspired various inmates, from James Stockdale to Nelson Mandela.”
