Summary and Keywords
The concept of security is central to the study of international relations (IR), yet it remains heavily contested, both in theory and in practice. In part, this is because the concept contains intractable tensions and contradictions. Nevertheless, or perhaps as a result of this, security—if understood as a state of being that is a function of war and peace—has been the subject of ethical reflection for millennia. Greco-Roman, Judeo-Christian, and Islamic traditions, among others, all have their own conceptions of how war and violence ought to be addressed. One of the more prominent ideas drawn from these debates is the concept of the just war, which emerged from the Christian tradition. It became an influential source of critical reflection upon both legal and practical dilemmas in international security, informing a wide range of debates around the world, and it has persisted at the heart of the field of Security Studies that emerged post-World War II. However, in the last couple of decades of the 20th century, changing notions of legitimate authority and broadened conceptions of conditions that cause harm and insecurity led to challenges to state-centrism and war-centrism in Security Studies. Issues such as global health security, counterterrorism, and humanitarian intervention have demonstrated the inherent tensions within security practices and demand novel ethical engagement. Approaching the issue of security from the perspective of international political theory (IPT) allows us to probe the ethical dimensions of security and ask how justice, authority, and security are linked and with what consequences.
