From a critical security studies perspective is the concept of human security something which should be taken seriously? Does human security have anything significant to offer security studies? Both human security and critical security studies challenge the state-centric orthodoxy of conventional international security, based upon military defence of territory against threats. Both also challenge neorealist scholarship, and involve broadening and deepening the security agenda. Yet critical security studies have not engaged substantively with human security as a distinct approach to non-traditional security. This article explores the relationship between human security and critical security studies and considers why human security arguments have not made a significant impact in critical security studies. The article suggests a number of ways in which critical and human security studies might engage. In particular, it suggests that human security scholarship must go beyond its (mostly) uncritical conceptual underpinnings if it is to make a lasting impact upon security studies, and this might be envisioned as Critical Human Security Studies (CHSS).
