A.O. Scott says
And, indeed, “Examined Life” is less a tour of present-day philosophy than a study in academic celebrity. Ms. Taylor has offered each of her subjects the chance to show off a little, and they find different ways of rising to the opportunity of subverting it. Some, like Mr. Zizek, Mr. Hardt and the Princeton ethicist Peter Singer, explicitly comment on their surroundings. Judith Butler, a gender theorist at the University of California, Berkeley, makes the act of taking a walk into an occasion for philosophical inquiry. Accompanied by the filmmaker’s sister Sunaura Taylor, who uses a wheelchair because of a disability, Ms. Butler in effect transposes some of her difficult and subtle ideas about bodies, identity and social space into the language of everyday life.
