Through her multifaceted work, the Bulgarian-born, Brooklyn-based writer, reader, and researcher Maria Popova, founder of the “free, ad-free, A.I.-free, fully human” website and newsletter The Marginalian, braids together literature, science, philosophy, poetry, and art in beautiful, alchemical ways. Traversing centuries, she approaches various ideas and thinkers, living and dead, as active references in the expansive, ongoing project of learning what it means to be human. Now, nearly 20 years since the site’s founding, she continues to cultivate a singular space on the internet—one devoted not so much to information but to illumination. Her latest book, Traversal, which links figures such as Mary Shelley and Walt Whitman, alongside other writers, poets, physicists, and philosophers, serves as an intellectual journey and an across-time meditation on creativity, consciousness, and interconnectedness. On this episode of Time Sensitive, Popova discusses the idea of “spiritual ancestors,” why today’s A.I. debates are fundamentally modern versions of age-old questions about the soul, and the mystery of being alive.
