“…This common starting point notwithstanding, IR research on ontological security is characterized by increasing diversity with constructivist (Berenskoetter, 2014; Berenskoetter and Giegerich, 2010; Flockhart, 2016), post-structuralist (Browning, 2019; Eberle, 2019; Kinnvall, 2004, 2018), and post-colonial (Agius, 2017; Shani, 2017; Untalan, 2020; Vieira, 2018) approaches being developed. Recently, this internal heterogeneity seems to have prompted a terminological shift away from Ontological Security Theory (OST), a label that might be taken to imply a single standardized theory, toward OSS (Donnelly and Steele, 2019; Steele, 2019; Steele and Homolar, 2019) as a way to better capture the plurality of approaches. Irrespective of the precise denomination, however, ontological security has proved fruitful for addressing a wide variety of theoretical and empirical concerns.…”
