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.

Naomi Shihab Nye says writing is “an act that helps you, preserves you, energizes you in the very doing of it.” She calls herself a “wandering poet,” and her words point to shining corners of beauty in the world we see every day.

Philosopher Kwame Anthony Appiah offers hope for quiet, sustained culture shift through the “endless shared conversation” of friendship. The writer of the New York Times “Ethicist” column studies how deep social change happens across time and cultures. “If you have that background of relationship between individuals and communities that is conversational, then when you have to talk about the things that do divide you, you have a better platform.”

“There is a place inside me that is far more powerful than the continuous mental noise,” says Eckhart Tolle. The spiritual teacher began to gain attention with his 1997 book, The Power of Now. Millions of people around the world have found pragmatic tools in his vision that fundamentally complicates the notion, “I think, therefore I am.”

“Imagine yourself alone on this planet. Would anything be the same?” Jennifer Michael Hecht is a poet, philosopher, and historian who wants to change the way we talk to ourselves and each other about suicide and staying alive — starting with her insistence that we believe each other into being. “Sometimes when you can’t see what’s important about you, other people can.”

Editor’s note: Given the focus of Jennifer Michael Hecht’s work, this episode briefly touches on the topic of suicide.

“Who am I?” Brazilian writer Paulo Coelho reframes the practice of pilgrimage as a journey into this mysterious question. “We have every single day this possibility, this chance of discovering something new,” he says.

When the wise and whimsical Sharon Olds started writing poetry over 40 years ago, she explored the subjects that interested her most — like diaphragms. “The politeness and the prudity of the world I grew up in meant that there were things that were important to me and interesting to me, [but] I had never read a poem about,” she once said. She won the Pulitzer Prize in 2013 for her collection Stag’s Leap about walking through the end of a long marriage. Her most recent book, Odes, pays homage to the human body and experience.
