Volunteers for Isis are surfing for the sublime and all that is lacking in the jaded, tired world of democratic liberalism, especially on the margins where Europe’s immigrants mostly live. Many are just “vacationers” for jihad, going to Syria over school breaks or holidays for the thrill of adventure and a semblance of glory. The beheadings are doing what the images of the collapsing twin towers did for al-Qaida, turning terror into a display of triumph over and through death and destruction. In Burke’s sense, a display of the sublime. As philosopher Javier Gomá Lanzón recently mused: is this sense of the sublime part of Isis’s attraction? Is the west’s failing its cynicism about a visceral rather than purely intellectual quest for meaning?
