Suketu Mehta tells a story about pinkie fingers, dancing and kissing. It is as confounding as it sounds. And utterly heartbreaking, too. In his assertive and essential new book, This Land Is Our Land: An Immigrant’s Manifesto—as well as on this episode of Time Sensitive—he describes the scene: Friendship Park, a half-acre fence on the U.S.-Mexican border. A Mexican man living in the U.S., who hasn’t seen his mother in 17 years, and has been working hard to send money back to her all that time, at last reunites with her at that fateful fence. But because of its thick and rigid design, he can’t see her clearly. Through the holes in the fence, mother and son can only fit stick their pinkies, wagging them back and forth, gently touching, caressing, connecting—but only for a few moments. This small act serves as a greater metaphor about immigration, one with vast implications and consequences, and not just in America but around our world today.

Mehta, a Calcutta-born, New York–based journalist and N.Y.U. professor who was a Pulitzer Prize finalist for his 2005 novel Maximum City: Bombay Lost and Found, is full of stories like this one. (The dancing, kissing pinkies, however, may be among his most gut-wrenching and tear-inducing tales.) As a reporter and writer, Mehta is slow and methodical in his approach, and it shows in his rich and varied body of work, which spans decades and is written with the elegance and grace of a poet. A sort of modern-day Walt Whitman, he has the rare ability to home in on deeply personal human stories and craft narratives around them that reveal larger truths about culture, politics, and society.

On this episode, Mehta speaks with Spencer Bailey about his challenging high school years as an Indian immigrant growing up in Queens, his belief in how the future of democracy “rests on storytelling,” and the importance of considering historical time frames when thinking about today’s contentious immigration debates.
