This chapter charts the existing literature on ethics in security studies and -where relevant - related subjects. The purpose of this is to point to existing gaps in the literature; gaps which Just Securitization Theory competently fills. The chapter proceeds by separating the existing literature into approaches concerned with the ethics of security (i.e. reflections on the concept of security itself, including what it should be) and normative reflections on the practice and value of security as a special kind of politics (we might call this the ethics of securitization, whereby securitization designates security as a process, or a special kind of action as distinct from security as a state of being). It is argued that while perhaps more work has been done on the ethics of security as a state of being, works on the normative value or disvalue of securitization have been disproportionally influential. Although some scholars are bucking this trend, I show that we do not currently have a systematic normative theory of security that applies to all actors and threats across the entire range of security sectors. Taken together this is the starting basis for Just Securitization Theory.
