After 2016, is that dream still possible? Some perspective is in order. This newspaper believes that Brexit and a Trump presidency are likely to prove costly and harmful. We are worried about today’s mix of nationalism, corporatism and popular discontent. However, 2016 also represented a demand for change. Never forget liberals’ capacity for reinvention.

The task is to harness that restless urge, while defending the tolerance and open-mindedness that are the foundation stones of a decent, liberal world.
