This article examines the growing relationship between security and education, particularly in the light of the UK government’s Prevent Duty that seeks to tackle radicalization in a variety of milieus, including universities. However, rather than seeing this process as being merely one-way, through a so-called securitization of education, what is explored here is the dialectic between these two spheres. It is suggested that a heightened sensitivity to the supposed consequences of inflammatory rhetoric on the well-being of supposedly suggestible or vulnerable students has been in existence within education for quite some time.
