At a time when the external borders of Europe and the entire West are being reinforced more than ever, and the inhabitants of the Global South are being reduced to less than nothing, any theoretical intervention that disrupts this hardened consensus is especially welcome. Heins and Wolff, on the one hand, provide a wealth of empirical material — particularly valuable are their insights into the (para-)agency Frontex — and, on the other, return to fundamental reflections on the effects of enclosure on the internal dynamics of society. A society that closes itself off is, of course, no longer open; however, this does not necessarily mean it is simply closed, tyrannical, and restrictive. The transformation produced by obsessive enclosure from the outside is much more complex, far more elusive, and, in the long run, significantly more dangerous. Some may believe they know what awaits us at the end of this path. But if the process continues in the direction in which political and fabricated popular consensus wishes to push us, the final destination will be so foreign and inhospitable that we, too, will wish to flee.
