War

Some reject the very idea of the “morality of war”.[1] Of those, some deny that morality applies at all once the guns strike up; for others, no plausible moral theory could license the exceptional horrors of war. The first group are sometimes called realists. The second group are pacifists. The task of just war theory is to seek a middle path between them: to justify at least some wars, but also to limit them (Ramsey 1961). Although realism undoubtedly has its adherents, few philosophers find it compelling.[2] The real challenge to just war theory comes from pacifism. And we should remember, from the outset, that this challenge is real. The justified war might well be a chimera. However, this entry explores the middle path between realism and pacifism. It begins by outlining the central substantive divide in contemporary just war theory, before introducing the methodological schisms underpinning that debate. It then discusses the moral evaluation of wars as a whole, and of individual acts within war (traditionally, though somewhat misleadingly, called jus ad bellum and jus in bello respectively)
