In A General Theory of Love, psychiatrists Thomas Lewis, Fari Amini, and Richard Lannon unravel one of humanity’s oldest mysteries with a startling truth: love isn’t just a feeling—it’s a biological necessity written into the architecture of the human brain. Through the lens of neuroscience and evolutionary psychology, they reveal that our deepest bonds are not mere matters of choice, but neural imperatives shaped by the limbic system. With prose as lyrical as it is scientific, the authors trace how early emotional experiences sculpt our hearts and minds, why our relationships can heal—or harm—us at the cellular level, and how genuine connection can rewire our brains. This episode doesn’t just review a book—it opens the door to understanding why love can be our greatest strength, or our undoing, and how the science of emotion can set us free.
