HarperCollins | $34.99 | pages In our fight with Covid-19 we have supported authoritarian measures and suspended the shared commerce of daily life that holds together the delicate tissue of democracy. The virus that travelled here from Wuhan has weakened our immunity to the virus of tyranny. That is Stan Grant’s contention in his latest book, With the Falling of the Dusk. “We find ourselves now at a hinge point in history,” he writes, and he has an ominous view of the prospects we face. After more than a year of disruption and uncertainty — a time when coping with anxiety was a major challenge — this might seem like the last perspective we need. In spite of its portentous title, though, the book is no empty indulgence in doomsaying. Grant wants to make an urgent case for a fundamental political reorientation.
