Book excerpt: When he stands before Giorgione's La Tempesta, Booker Prize-winning author John Berger sees not only the painting but our whole notion of time, sweeping us away from a lost Eden. A photograph of a gravely joyful crowd gathered on a Prague street in November 1989 provokes reflection on the meaning of democracy and the reunion of a people with long-banished hopes and dreams. With the luminous essays in Keeping a Rendezvous, we are given to see the world as Berger sees it -- to explore themes suggested by the work of Jackson Pollock or J. M. W. Turner, to contemplate the wonder of Paris. Rendezvous are manifold: between critic and art, artist and subject, subject and the unknown. But most significant are the rendezvous between author and reader, as we discover our perceptions informed by Berger's eloquence and courageous moral imagination.
