At The Times we like a good argument. The passionate, rigorous defence of an idea is the stock in trade of our Opinion pages. That’s why so many of our writers and readers take part in The Battle of Ideas, a weekend of informed, but informal jousting among the intellectually curious. If you don’t want your arguments limited to 140 characters, prepare your thoughts and get ready to do battle. If you do, join in online at http://www.timesonline.co.uk/tol/system/topicRoot/Battle_of_Ideas/ or join the twitter feed at http://twitter.com/instofideas
