Archbishop Desmond Tutu is one of our wisest models on the territory of reckoning with past wrongs that infuse and haunt the present. In the 1990s, he helped galvanize South Africa’s peaceful transition to democracy after decades of white supremacy as the law of the land. He tells a story of how healing and human redemption unfold from his time chairing the Truth and Reconciliation Commission, which granted amnesty to those who would fully confess their crimes. “Human beings can leave you speechless, really. They can leave you speechless by the horrible things they do, but they also leave you speechless with the incredible things,” he says.

The physicist Leonard Mlodinow changes how we think about the agency we have in shaping our own destinies. As a scientist, he works with principles like Brownian motion, by which Einstein helped verify the existence of molecules and atoms. As the child of Holocaust survivors, he dances with the experience we all have: that life never goes as planned, and yet the choices we make can matter. “The course of your life depends on how you react to opportunities and challenges that randomness presents to you,” he says.

Public theologian Ruby Sales opens up what it was like to be a teenage participant in the civil rights movement — including the impatience she had with religion and how she circled back, through her experiences of the movement, to a sense of the deep reason for inner life and religious groundings. The question she carries with her, “Where does it hurt?”, models new ways for us to understand one another.

Men of all ages say Richard Rohr has given them a new way into spiritual depth and religious thought through his writing and retreats. This conversation with the Franciscan spiritual teacher delves into the expansive scope of his ideas: from male formation and what he calls “father hunger” to why contemplation is as magnetic to people now, including millennials, as it’s ever been.

Naturalist Terry Tempest Williams brings meaning and direction to the grief around ecological loss and climate change. She’s a self-described “citizen writer” rooted in the American West, and she draws connections between fierce love and hard work — both in the natural world and the human world. “It all comes down to relationships, to place, to paying attention, to staying, to listening, to learning — of a heightened curiosity with other,” Williams says.

Father James Martin is a beloved Jesuit writer and teacher who says desire is not selfish, but rather a path to understanding our callings in life. He believes everyone has a vocation we can find by asking: What moves me? “We all have an image of the person we want to become — more loving, more open, more free. That’s a call,” he says.

Matthieu Ricard is helping us redefine happiness in a culture convinced that it’s a passive experience. The French-born Tibetan Buddhist monk reframes happiness not as pleasure but as practice that requires discipline — akin to marathon training or learning chess. He asks, “What are the inner conditions that foster a genuine sense of flourishing, of fulfillment?”

Astronomer Natalie Batalha embodies a planetary sense of what “love” is and means. She says her experience searching the universe for exoplanets — earth-like bodies beyond our solar system that could harbor liquid water and life — fundamentally shifted how she thinks about the human experience on this planet. “You see the expanse of the cosmos, and you realize how small we are and how connected we are,” she says. “And that what’s good for you has to be good for me.”

A civil rights elder and speechwriter for Martin Luther King, Jr., the late Vincent Harding brought the wisdom of the movement to young people in hurting places. He offers the image of a “live human signpost” as a guiding light toward the kind of support and mentorship we can offer one another in the path toward a beloved community. “When it comes to creating a multiracial, multiethnic, multireligious, democratic society, we are still a developing nation,” he says. “But my own deep, deep conviction is that the knowledge, like all knowledge, is available to us if we seek it.”

Rami Nashashibi is a champion for how art can make humans visible to each other. He brings a new energy to Islam’s core commitment to beauty and humanity — and to the power of stories to heal and electrify us across geography and generation, culture and faith. He founded the Inner-City Muslim Action Network on Chicago’s South Side, where he also lives with his family. “The arts have become the real factor for us in both humanizing each other’s stories, connecting our stories, and revealing to one another the possibilities of what a better world can look like,” he says.

A rabbi and parent, Sandy Eisenberg Sasso wants us to think about how we might teach our children’s souls, not just their minds. She says nurturing the spiritual lives of our children is the work of understanding for ourselves “what really matters in life, what’s precious, what’s more important than earning a living and going through our daily routine.”

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.
