In today's click-happy world, humour all too often strikes at the heart of the other. It's about laughing at another's expense, guffawing in superiority, and generally casting our eye on other people's failings. Walter G Moss reminds us that this social habit is a long way from what humour once was -- a method to maintain perspective, and to look at the world in such a way that we can overcome whatever hits us. Life can be funny -- not just other people's lives, but our own lives. Moss says this very ability is a sign of both maturity and of wisdom. When we laugh at ourselves, all the world can laugh with us.
