This week, we pay tribute to the activist, essayist, and critic Susan Sontag. 15 years after her death, Sontag's perspectives on language, sexuality, and politics still resonate. She elevated art forms like film and photography, and believed that dedication to high culture was in itself a form of activism. On October 2, 2019, biographer Benjamin Moser and writer and activist Rebecca Solnit came to the Sydney Goldstein Theater in San Francisco to discuss the life, work, and legacy of Susan Sontag.
