I was down in London yesterday to record my first column for BBC Radio 3 Night Waves. The science media is all a-buzz about ‘analogy’ at the moment after the publication of the new book by Pulitzer prize winning cognitive scientist Douglas Hofstadter and his collaborator, French psychologist Emmanuel Sander: Surface and Essences: Analogy as the Fuel and Fire of Thinking. They argue that rather than analogy just being a part of reasoning, it it actually the key to cognition – the only way we understand anything is by comparing it to something we already know. Interested by their arguments, I take a look at how analogy figures in literature and science and what is can tell us about the relationship between them. It’ll be broadcast sometime next week – I’ll post the link when it comes out, so watch this space.
