Is God a delusion? Is lying always wrong or violence ever justifiable? Could you know if the universe had doubled in size overnight? And should arguments always be reasonable? These are just some of the questions to be discussed at a public "arguing" event on the University of Kent's Canterbury campus during its Open Day on 4 October. The event, which has been organised by Laurence Goldstein, professor of philosophy, is titled "For the Sake of Argument". Professor Goldstein said: "Arguing is an intrinsically enjoyable activity, and sometimes a view may be put forward that is so subtle and persuasive that it can be savoured like a work of art or a piece of music. Arguing is also the best way to develop argumentative skill. This involves the ability to devise good reasons, to express oneself clearly and rigorously, to understand an opponent's position and either refute it or abandon or modify one's own position in response."
