"The pre-Enlightenment mindset of the Out campaign has little time for values. Human rights are cast as a European plot. Never mind that Britain was a moving force in creating the European Court of Human Rights. Migrants are demonised as criminals and scroungers. Ironically, the self-styled upholders of parliamentary sovereignty want to overturn, well, parliamentary sovereignty: two-thirds of MPs oppose Brexit.
There is hard-headed interest here alongside the moral dimension. The open international system on which security and prosperity rest is in turn rooted in the rule of law. Britain, with global interests, is particularly reliant on a rules-based system. Throw away the values underpinning the rules and you invite a return to Hobbesian chaos.
None of this, one supposes, troubles Brexiters. Theirs is the mantra of populists through the ages: go on, give the establishment a kick. You can see the appeal. But look at the cost."
