A Buddhist philosopher of ecology, Joanna Macy says we are at a pivotal moment in history with the possibility to unravel or create a life-sustaining human society. Now entering her 90s, Macy has lived adventurously by any definition. She worked with the CIA in Cold War Europe and the Peace Corps in post-colonial India and was an early environmental activist. She brings a poetic and spiritual sensibility to her work that’s reflected in her translations of the early-20th-century poet Rainer Maria Rilke. We take that poetry as a lens on her wisdom on the great dramas of our time: ecological, political, personal.

She has called Brain Pickings, her invention and labor of love, a “human-powered discovery engine for interestingness.” What Maria Popova really delivers, to hundreds of thousands of people each day, is wisdom of the old-fashioned sort, presented in new ways. She cross-pollinates between philosophy and design, physics and poetry, the intellectual and the experiential. We explore her gleanings on what it means to lead a good life — intellectually, creatively, and spiritually.

The poet, essayist, and playwright Claudia Rankine says every conversation about race doesn’t need to be about racism. But she says all of us — and especially white people — need to find a way to talk about it, even when it gets uncomfortable. Her bestselling book, Citizen: An American Lyric, catalogued the painful daily experiences of lived racism for people of color. Claudia models how it’s possible to bring that reality into the open — not to fight, but to draw closer. And she shows how we can do this with everyone, from our intimate friends to strangers on airplanes.

Pico Iyer is one of our most eloquent explorers of what he calls the “inner world” — in himself and in the 21st century world at large. The journalist and novelist travels the globe from Ethiopia to North Korea and lives in Japan. But he also experiences a remote Benedictine hermitage as his second home, retreating there many times each year. In this intimate conversation, we explore the discoveries he’s making and his practice of “the art of stillness.”

Brain surgeon James Doty is on the cutting edge of our knowledge of the brain and the heart: how they talk to each other; what compassion means in the body and in action; and how we can reshape our lives and perhaps our species through the scientific and human understanding we are now gaining.

Tracy K. Smith has a deep interest in “the kind of silence that yields clarity” and “the way our voices sound when we dip below the decibel level of politics.” She’s a welcome voice on the little leaps of the imagination that can restore us. She’s spent the past year traversing our country, listening for all of this and drawing it forth as the U.S. Poet Laureate. Krista spoke with her at the invitation of New York’s B’nai Jeshurun synagogue, which has been in communal exploration on creating a just and redeemed social fabric.

“People believe things that are mutually contradictory; I think we all do. I know I do.” — Erick Erickson

Earlier this year, the University of Montana invited On Being to attempt an outside the box civil conversation between two political pundits on contrasting ends of the U.S. political spectrum. It became a sold-out, public event in the spirit of Montana’s Senator Mike Mansfield, who famously modeled integrity, courage, and humility across the partisan aisle in the tumult of 1960s and 70s. Sally Kohn and Erick Erickson are both controversial, lightning-rod figures, yet neither of them fits neatly into a partisan mold. The reaction of the youngest people in the room is what compelled us to put this on the air. They said they had not witnessed or imagined a political conversation like this possible: one marked at once by bedrock difference — and good will, humor, and a willingness to bring our questions as well as our arguments, our humanity as well as our positions, into the room, if only for an evening.

An exuberant experience of conversation and singing. There are nearly 5,000 spirituals in existence. Their organizing concept is not the melody of Europe, but the rhythm of Africa. They were composed by slaves, bards whose names we will never know, and yet gave rise to gospel, jazz, blues, and hip-hop. Joe Carter lived and breathed the universal appeal and hidden stories, meanings, and hope in what were originally called “sorrow songs.” This was one of our first weekly shows, and it’s still one of our most beloved.

We don’t really reward or allow our politicians, good or bad, to be searching, or to change their minds and grow — to admit their human frailty. So it’s surprising to hear Cory Booker say that the best thing that’s happened to him is “being broken, time and time again.” He’s taken flack for talking about politics as “manifesting love.” He speaks with Krista about the inadequacy of tolerance, strengthening the “muscle” of hope, and making your bed as a spiritual practice.

Maria Shriver’s life is often summarized in fairy tale terms. A child of the Kennedy clan in the Camelot aura of the early 1960s. Daughter of Eunice Kennedy Shriver, who founded the Special Olympics, and Sargent Shriver, who helped found the Peace Corps. An esteemed broadcast journalist. First lady of California. This hour, she opens up about having a personal history that is also public history — and how deceptive the appearance of glamour can be. We experience the legendary toughness of the women in Maria Shriver’s family — but also the hard-won tenderness and wisdom with which she has come to raise her own voice.
