Jorge Luis Borges's fantasy novels stand out in the world in light of their indistinguishable nature between virtuality and reality embodying philosophical contemplations.In his writing,he uses strategies such as rigorous research and authoritative endorsement,quasi-realist background,and documentary style to blur the boundary between fiction and reality,combines rich imagination with abstract philosophical thinking,and presents them in a highly functional form of fantasy,which not only makes an extraordinary effort to realize the fictional legitimacy of novels,but also contributes remarkably to the expansion of imagination in novel writing.
