Life off Earth: are the aliens out there?
"I was impressed by the intensity of the debate and the high level of intellectual engagement, not least by the audience. It was an invigorating, even exhilarating experience to be part of a festival based on the conviction that disagreement is good. The Battle of Ideas is a fantastic concept, may it spread epidemically to the rest of the world. I am already looking forward to next year's event."
