Capitalism, he wrote in Ways of Seeing, “survives by forcing the majority to define their own interests as narrowly as possible”. It was narrowness he set himself against, the toxic impulse to wall in or wall off. Be kin to the strange, be open to difference, cross-pollinate freely. He put his faith in the people, the whole host of us.
The book of his I pick up more & more often as I get older is his collaboration with Jean Mohr, A Fortunate Man: The Story of a Country Doctor. I have a beaten-up old paperback–from the early 70s, I think–which doesn’t get any easier to read without it falling to bits; but it’s now available from Canongate with an introduction by Gavin Francis, who describes it in his first sentence as “a masterpiece of witness”. That was what Berger felt like back then, and what he made me want to become: a witness.
