A rigorously researched and intensely moving examination of empathy. Beam carves through the noise with a revelatory exploration of how we perform empathy, how it is learned, what it can do - indeed, what empathy is in the first place. She takes us to the labs where the neural networks of compassion are being mapped, and the classrooms where children are being trained to see others' views. Beam visits courtrooms and prisons, asking how empathy might transform our justice system. She travels to places wracked by oppression and genocide, where reconciliation seems impossible, to report on efforts to heal society's deepest wounds through human connection.
