A philosopher’s questioning and a scientist’s eye shape Enrique Martínez Celaya’s original approach to art and to life. A world-renowned painter who trained as a physicist, he’s fascinated by the deeper order that “whispers” beneath the surface of things. Works of art that endure, he says, possess their own form of consciousness. And a quiet life of purpose is a particular form of prophecy.

A passionate translator of the beauty and relevance of scientific questions, Margaret Wertheim is also wise about the limits of science to tell the whole story of the human self. Her Institute for Figuring in Los Angeles reveals evocative, visceral connections between high mathematics, crochet and other folk arts, and our love of for the planet.

Singing is able to touch and join human beings in ways few other arts can. Alice Parker is a wise and joyful thinker and writer on this truth, and has been a hero in the universe of choral music as a composer, conductor, and teacher for most of her 90 years. She began as a young woman, studying conducting with Robert Shaw at Juilliard, and collaborated with him on arrangements of folk songs, spirituals, and hymns that are still performed around the world today.

The Brazilian lyricist Paulo Coelho is best known for his book, The Alchemist — which has been on the New York Times bestseller list for over 400 weeks. His fable-like stories turn life, love, writing, and reading into pilgrimage. In a rare conversation, we meet the man behind the writings and explore what he’s touched in modern people.

Something of a celebrity in Quaker circles, Carrie Newcomer is best known for her story-songs that get at the raw and redemptive edges of human reality. This week, a musical conversation with the Indiana-based and born folk singer-songwriter who’s been called a “prairie mystic.” She writes and sings about the grittiness of hope and the ease of cynicism.

The philosopher Simone Weil defined prayer as “absolutely unmixed attention.” The artist Ann Hamilton embodies this notion in her sweeping works of art that bring all the senses together. She uses her hands to create installations that are both visually astounding and surprisingly intimate, and meet a longing many of us share, as she puts it, to be alone together.

Eve Ensler has helped women all over the world tell the stories of their lives through the stories of their bodies. Her play, “The Vagina Monologues,” has become a global force in the face of violence against women and girls. But she herself also had a violent childhood. And it turns out that she, like so many Western women, was obsessed by her body and yet not inhabiting it without even knowing she wasn’t inhabiting her body — until she got cancer.

Computer scientist Bernard Chazelle has an original take on what music works in us — especially the music of Johann Sebastian Bach. Just as mathematicians talk about discovering rather than inventing great equations, so, he says, Bach set out to “discover” the musical rules behind the universe. After hearing this conversation, you may never listen to any piece of music — whether Bach or Jay-Z — in quite the same way again.

As the daughter of Johnny Cash, singer-songwriter Rosanne Cash describes her life as “circumscribed by music.” But, it’s through her love of language and quantum mechanics that she’s finding new sources of creativity and mathematical ways to think about the divine. The mother of five shares her perspectives on being present, Twitter as a “boot camp for songwriters,” and how she wrestles with love and grief through her music.

He is a genius of improvisation; a genre-bending vocal magician and conductor. And he sings the territory between music, mystery, and spirit. Who better to contemplate the human voice — its delights, its revelations, and its mystery — than Bobby McFerrin?

A kind of archeologist of the human voice, singer and composer Meredith Monk says that “the voice could be like the body” — flexible and fluid with practice. Through music as through meditation, the longtime Buddhist practitioner pushes the boundaries of what we can do without words.
