A team of philosophers from the University of Reading (Geraldine Ng, Joe Donnolly and Rhianwen Daniel) descended on Chigwell for a double-bill of philosophy, centred around our responsibility (or lack of it) for global warming. Why shouldn’t I drive my gas-guzzling 4×4? What difference would not driving actually make to the temperature of the planet and the sea-level around the Maldives? Through carefully structured questioning, the team from Reading teased out thoughtful responses from our students, and made us look again at what might have seemed simple ethical questions.
