' The Big Questions' series is designed to let renowned experts confront the 20 most fundamental & frequently asked questions of a major branch of science or philosophy. In ' The Big Questions: Ethics' Julian Baggini, one of Britain's best-known philosophers, condenses complex, contemporary issues of right & wrong into 20 key questions. He examines how we can start to answer them, what they might mean to us & how they influence the way we choose to live our lives. Among the ideas debated are: What is free will? Can it ever be right to kill? Is terrorism ever justified? Should euthanasia be legal? Are some people superior to others? Do animals have rights?
