Can war ever be justified? Why is it wrong to kill? In this new book Richard Norman looks at these and other related questions, and thereby examines the possibility and nature of rational moral argument. Practical examples, such as the Gulf War and the Falklands War, are used to show that, whilst moral philosophy can offer no easy answers, it is a worthwhile enterprise which sheds light on many pressing contemporary problems. A combination of lucid exposition and original argument makes this the ideal introduction to both the particular debate about the ethics of killing and war, and also to the fundamental issues of moral philosophy itself.
