The sequel to the hugely acclaimed "Big Numbers", "Big Questions" brings the most challenging issues about life, the universe and everything to 10-13 year olds. Is there a reason for everything? Can you trust the experts? Can you prove who you are? Do animals have rights? Does anything really exist? Is there only one answer? Asking questions can be a very risky business. When we start to think about things we've always taken for granted, we can end up with some surprising results. "Big Questions" is full of entertaining and challenging questions about the world around us - many of them have been puzzled over for thousands of years. The book includes sections on How to Win an Argument, Mind, Bodies and Brains and Right and Wrong.
