This article examines how philosophers have approached the ethics of war, from Socrates to contemporary discussions. Philosophers throughout history have actively participated in combat and developed ethics of war that continue to inform doctrines of war, but these ethics also have shortcomings that require reevaluation. Factors such as national origin and religious beliefs have significantly influenced philosophical perspectives throughout history. However, philosophical approaches do not consistently align with these factors; some philosophers criticize the military positions of their own countries, while others misuse religious ethics in their arguments. Furthermore, philosophers sometimes change their views after conflicts arise, disregard historical facts and theological foundations, overlook the approaches of earlier scholars, even while drawing from them, and may even endorse harmful ideologies. The history of ethical philosophy related to questions of war presents scholars from diverse backgrounds with ample opportunities to explore the complexities of warfare.
