Doris Lessing, the winner of Nobel Prize for Literature in 2007, produces a series of science fiction novels, Canopus in Argos: Archives, which analyze and criticize the existing social contradictions and conflicts from a unique angle. The author puts forward, by adopting metaphor, metonymy, megametaphor, analogy and ‘strong analogy’, her own understanding on how to develop a safe and healthy human world for our descendants, and emphasizes the critical role the human collective strength and wisdom play during the change of times and in the turning points of human destiny. This article attempts to discuss the profound connotation by interpreting the content of the novels, and study the metaphor of human destiny in them. It also calls on researches on Lessing's science fiction works by the domestic scholars.
