Doris Lessing started as a realistic novelist, but the publication of The Golden Notebook (1962), marks a turning point in her career. In 1957 she had praised nineteenth- century realism as the highest form of literature but five years later she changed her previous attitude and abandoned her previous opinions because that form of the novel would not suit her to 'play' with time and memory (1) . In Briefing for a Descent into Hell (1971), The Summer before the Dark (1973), The Memoirs of A Survivor (1975), Shikasta (1979), The Sirian Experiment (1981), Lessing has been experimenting with techniques related to nonrealistic modes such as expressionism, fantasy, science fiction, and allegory. A Lessing novel or story often offers a world of practical reality on the one hand, while on the other her reader is projected into a world whose dimensions are more of those of The Arabian Nights or a dream as we are going to see in The Memoirs of A Survivor . Doris Lessing has given the disintegration of the self a close attention, and she sees it steadily as a kind of experience, and an end in itself. There are no over tones or promises, and she is only " writing about human beings and how they can still operate under near- zero conditions ).
