A genius maligned, this one. Susan Sontag was indeed what Carl Rollyson calls her, "the most important public intellectual of her generation". She was perfect for the Sixties: Mod, hip, ever ready to epater le bourgeoisie, flippant, beautiful, and spoke French. The subjects of her essays, Godard, Cioran, Levi-Strauss, Bergman, were all au courant. She knew film, fashion and fiction. Sontag's political commitments, the famous trip to Hanoi at the height of the Vietnam War, for and later against the Castro regime in Cuba, perfectly fit the temper of youth protesting out in the streets. Her ambiguous feelings towards feminism reflected both her privileged upbringing and wish for privacy concerning her sex life. When the calendar turned from 1969 to 1970 Sontag flipped too; devoting her writing more towards personal hobbies, photography, and her own battle with cancer (ILLNESS AS METAPHOR). All this makes for a fascinating portrait, so why is this biography so lifeless and dull? The writing is pedestrian and Rollyson never gives a hint on why he considers Sontag worthy of a revisit after several other biographers of late have scrutinized her life. Valuable end notes are the only point of interest in this latest entry in Sontag studies.
