Surrealism is often confused with magical realism as they both explore illogical or non-realist aspects of humanity and existence. There is a strong historical connection between Franz Roh's concept of magic realism and surrealism, as well as the resulting influence on Carpentier's marvelous reality; however, important differences remain. Surrealism "is most distanced from magical realism [in that] the aspects that it explores are associated not with material reality but with the imagination and the mind, and in particular it attempts to express the 'inner life' and psychology of humans through art." It seeks to express the sub-conscious, unconscious, the repressed and inexpressible. Magical realism, on the other hand, rarely presents the extraordinary in the form of a dream or a psychological experience. "To do so," Bowers writes, "takes the magic of recognizable material reality and places it into the little understood world of the imagination. The ordinariness of magical realism's magic relies on its accepted and unquestioned position in tangible and material reality."[50]
