Against the domination of moral deliberation by rights-talk In Defence of War asserts that belligerency can be morally justified, even while it is tragic and morally flawed. Recovering the early Christian tradition of just war thinking, Nigel Biggar argues in favour of aggressive war in punishment of grave injustice. This is a major contribution to the literature on the morality of war, written in two voices, one argumentative, the other reflective and open to other perspectives... a rich reflection on a wealth of literature, historical and contemporary, addressing the justifications for making war.
