At age 16, Reginald Dwayne Betts was sentenced to 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. In this profound talk, 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.

Wealth inequality gets talked about as an economic problem. Writer Xochitl Gonzalez makes the case that it’s a civic one, too — a slow, quiet threat to democracy. Drawing on her research into the psychology of social class, she shows how growing up with (or without) money changes how we experience politics, community and society. (Recorded at TED Democracy Philadelphia on June 13, 2026)

What sound came after the Big Bang? Astronomer Mark Whittle takes us back to the infant cosmos, where massive sound waves pulsed through primordial gas in a pattern that’s still traceable across the universe today. Working with sound artist Ander Mikalson and composer Caroline Shaw, he turns those ancient tones into a glorious, awe-inspiring choral work.
