A TED Talk, featuring, Reginald Dwayne Betts, who spent nine years in prison. He turned to books to help hold onto his sanity — and developed a belief that we find what we look for, even in the toughest places. Now a lawyer and poet, he’s opened hundreds of Freedom Libraries inside prisons across the US, putting books he once dreamed of reading into the hands of incarcerated people. He makes the case that hope is something people pass on to one another. “We put millions of people in prison. I would put millions of books inside,” he says. Watch now.
