Do philosophers have an obligation to public philosophy, that is, do they owe the pubic an effort to explain their work in a form that the public can understand and make use of? A prior question is whether public philosophy is possible, and this question is open because the role of the public philosopher may not be a possible role in our society. In Plato’s view, public philosophy was not possible in a democracy, as the only role for public philosophy was in a society in which philosophers were rulers. But the differences between our conception of democracy and Plato’s may show that his view of the social fate of the potential philosopher in a democracy does not hold for us.

What are the ethical principles underpinning the idea of a just war and how should they be adapted to changing social and military circumstances? In this book, Steven P. Lee presents the basic principles of just war theory, showing how they evolved historically and how they are applied today in global relations. He examines the role of state sovereignty and individual human rights in the moral foundations of just war theory and discusses a wide range of topics including humanitarian intervention, preventive war, the moral status of civilians and enemy combatants, civil war and terrorism. He shows how just war theory relates to both pacifism and realism. Finally, he considers the future of war and the prospects for its obsolescence. His clear and wide-ranging discussion, richly illustrated with examples, will be invaluable for students and other readers interested in the ethical challenges posed by the changing nature of war.

Modern warfare cannot be conducted without civilians being killed. In order to reconcile this fact with the principle of discrimination in just war theory, the principle is applied through the doctrine of double effect. But this doctrine is morally inadequate because it is too permissive regarding the risk to civilians. For this reason, Michael Walzer has suggested that the doctrine be supplemented with what he calls the idea of double intention: combatants are not only to refrain from intending to harm civilians; they are also to take precautions to reduce risk to civilians, even at the expense of increasing risk to themselves. The article develops the idea of double intention by addressing two questions: What does it mean to intend to reduce civilian risk, and how much should civilian risk be reduced? The results of this discussion are then used to consider a moral issue that arises in technologically asymmetric warfare, namely, the extent to which the use of precision-guided munitions, which allow more accurate targeting, can by itself bear the moral burden imposed by the principle of discrimination
