B the end of last year, anyone who had been paying even passing attention to the news headlines was highly likely to conclude that everything was terrible, and that the only attitude that made sense was one of profound pessimism – tempered, perhaps, by cynical humour, on the principle that if the world is going to hell in a handbasket, one may as well try to enjoy the ride. Naturally, Brexit and the election of Donald Trump loomed largest for many. But you didn’t need to be a remainer or a critic of Trump’s to feel depressed by the carnage in Syria; by the deaths of thousands of migrants in the Mediterranean; by North Korean missile tests, the spread of the zika virus, or terror attacks in Nice, Belgium, Florida, Pakistan and elsewhere – nor by the spectre of catastrophic climate change, lurking behind everything else. (And all that’s before even considering the string of deaths of beloved celebrities that seemed like a calculated attempt, on 2016’s part, to rub salt in the wound: in the space of a few months, David Bowie, Leonard Cohen, Prince, Muhammad Ali, Carrie Fisher and George Michael, to name only a handful, were all gone.) And few of the headlines so far in 2017 – Grenfell tower, the Manchester and London attacks, Brexit chaos, and 24/7 Trump – provide any reason to take a sunnier view.
