ABSTRACT
This chapter does three things. First, it sketches a very basic overview of perspectives on the question of expertise, outlining a nominalist approach focused on technologies of expertise rather than a more conventional sociological approach oriented to the characteristics of expert personnel. Second, the chapter voices some critical points of view concerning the concept of security itself and, briefly, its application in the historiography of security studies. Finally, we offer some ad hoc remarks on the work of Michel Foucault in so far as it is relevant to these concerns. The chapter does not contain a summative argument so much as a series of reflections, some of which will be more or less obvious, some perhaps slightly more contentious.
