Ever since Gao Xingjian gave his invited speech titled“Witness of Literature: Pursuit of the True” in Nobel Literature Prize Centennial Academic Symposium in The Swedish Academy,witness literature and literature as witness have been more and more paid attention to by people for years.The first novel A Pale View of Hills of last year’s Novel Prize Winner Kazuo Ishiguro can also be interpreted as a novel on witness of Japanese immigrants’ mentality of guilt and self-deception.The most significant characteristics of witness literature are historical accuracy,pursuit of reality and inquiry for truth.That is to say, as an author of witness literature,he or she has to be a observer and a recorder with firm conscience of the public intellectuals.American writer Susan Son-tag,who has been praised as “the conscience of the public intellectuals”,made quick,active and enthusiastic response to Victor Serge’s witness novel long time before researchers of Russian Witness Literature master Victor Serge.Sontag writes the article titled“Unextinguished:The Case for Victor Serge” for defending with passionate humanitarianism for life-writing witness novel of an author who believes in cosmopolitism while being doubly forgotten in histories of modern Russian literature and modern French literature.Through studying this article, we are not only acquainted with another Russian writer on exile and get to know their literature be-liefs and achievements.What’s more important, we also are conscious and gnosis of the truth that value of literature lies in authenticity,inferior of self-restraint,sympathy and feeling of compassion for pain and bitterness of “the other” in their association and writing of seeking contacts and insisting on dialogues.
