Third Ear braids together personal narrative with scholarly inquiry to examine the power of listening to build interpersonal empathy and social transformation. A child of Holocaust survivors, Rosner shares stories from growing up in a home where six languages were spoken to interrogate how diverse areas of scholarship such as psychotherapy, neurolinguistics, and creativity can illuminate the complex ways we are impacted by the sounds and silences of others. Drawing on expertise from journalists, podcasters, performers, translators, acoustic biologists, spiritual leaders, composers, and educators, this hybrid text moves fluidly along a spectrum from molecular to global to reveal how third ear listening can be a collective means for increased understanding and connection to the natural world.
