How do we know the difference between right and wrong? How can we make decisions about issues from germ-line genetic engineering to the regulation of banking, from nuclear power to ethnic bioweapons, from end-of-life care to global warming? What does it mean to live a good life? Ethics Matters introduces students and general readers to the business of making moral decisions, engaging them in meaningful dialogue and inspiring them to find out more. Beginning with a discussion of the question of truth in Ethics, Peter and Charlotte Vardy outline and evaluate major approaches to doing ethics from Natural Law and Virtue Ethics to Situation Ethics and Postmodernism, considering how these might inform decision making in today's world. Ethics Matters places the latest scholarship in context, clarifying how it relates to today's biggest challenges, without in any sense 'dumbing down'. The style is engaging and accessible; good use is made of examples from film, literature and current affairs to shine a light on the fundamental philosophic questions which underpin practical dilemmas. A new web site, www.what-matters.org provides recommendations for further reading, a rich anthology of primary texts, questions for discussion and related activities.
