Nine philosophers step out of the seminar room and into the world, each given a setting picked to sharpen their argument. Peter Singer works out the ethics of consumption while walking past the boutiques of Fifth Avenue. Cornel West talks philosophy as jazz and blues from the back seat of a car crossing Manhattan. Judith Butler and disability activist Sunaura Taylor walk through San Francisco's Mission District questioning the culture's obsession with independence. Slavoj Zizek delivers his segment standing in a garbage dump, using the trash itself to make a point about ecology and ideology. Michael Hardt considers revolution against a backdrop of wealth and leisure, and Kwame Anthony Appiah, Martha Nussbaum, and Avital Ronell each get a location matched to their subject. Director Astra Taylor keeps the format consistent across all nine: one thinker, one walk or ride, one argument delivered without jargon or a lectern, treating the city itself as the classroom.
