Kantian-inspired approaches to ethics are a hugely important part of the philosophical landscape in the 21st century, yet the lion's share of the work done in service of these approaches has been at the theoretical level. Moreover, when we survey writing in which Kantian-inspired thinkers address practical ethical problems, we do not often enough find sustained attention being paid to issues in military ethics. This collection presents a sampling of how an ethicist who takes Kantian commitments seriously addresses controversial questions in the profession of arms. It examines some of the less frequently studied topics within military ethics such as women in combat, military careerism, homosexuality, teaching bad ethics, immoral wars, collateral damage and just war theory. Presenting philosophical thinking in an easy to understand style, the volume has much to offer to a military audience.
