In this article we, the authors, outline the thematic concerns of our special issue of the Journal of Global Ethics . We argue for a need to engage with notions of violence from an interdisciplinary and transformative perspective. The theoretical framework that provides such a perspective is critical theory, broadly construed. Critical theory has always been concerned with the relation between practice and theory, as well as notions of violence. It is therefore surprising to note that in the current critical (...) theoretical debates a sustained engagement with the theme of violence has largely been sidelined. We argue that critical theory is not only fruitful for the study of conflict and violence, but also that such practical issues can shed and help further develop critical theory itself. (shrink)
