Security has a multi-layered definition, with different interpretations de­pending on the theoretical framework that studies it. The understanding of the concept has also evolved from what it meant in traditional interna­tional relations, where the focus was on the security of the state against external aggression, more specifically military security to what it signifies today, when the concept has expanded in scope and structure. This expan­sion of security’s scope was discussed by Barry Buzan, who explains that the concept of security is linked to survival, and for an issue to be consid­ered a security concern, threat whether military or non-military must be an “ existential threat to the referent object posed by a securitizing actor, which thereby generates support for urgent measures outside the rules that would otherwise be binding”(Buzan, 1997:13). A Historical Perspective on the Development of the Practice and Idea of Security Security itself has a relatively obscure history, certainly shorter than that of culture. The concept of security from more recent history belongs to the field of international relations and is a part of a broader political science discipline, with its own specific historical roots and culturally determined evolution. Before the mid-20th century, the term“security” was never used in relation to issues of international relations or, more generally, in the domain of politics. The end of World War II marked a period when this term began to be used, almost hesitantly, but it did not yet have the dominant role it plays today. In ancient times, the concept of security was primarily associated with the spirit and spirituality and was the essence of a theological idea. Security was understood as a disposition, a worldview, and a spiritual state, both psychologically and morally. The Greek word“ataraxia”(meaning a state of mind or peace) was used to describe a state of security(Burgess, 2008). During the transition to the Middle Ages,“ataraxia” was translated into Lat­in as“securitas”. In the moral logic of medieval Christianity,“securitas” ac­quired a negative connotation. Security was seen as an evident subjective characteristic, indicating a lack of emotional and spiritual problems, which was interpreted as a lack of engagement with them. Security was a personal matter, not connected to the state, society, or any other group, and largely remained morally and psychologically based. According to Burgess, if some­one is secure, they are also without interest and reflection, and thus without self-awareness, likely on the path to danger especially concerning“heavenly Chapter 1 – Security Culture as a Concept Synthesized From the Terms Culture and Security 37
