The paper develops the implicit as well as explicit meaning which evokes Stanisław Lem’s concept of the Body and the Corporality portrayed in the novel Return from the Stars. Moreover, Lem’s novel about an astronaut Hal Bregg and his return on Earth is analysed. In this novel author uses the idea of Einstein’s twin paradox. Hal Bergg—the stereotype of masculinity—is confronted with decadent and egalitarian society, which may be refers to the reunion masculinity with femininity. Such storyline shows the multidimensionality of the issue of Corporality, and presents the Body as a epistemological metaphor of modernism and postmodernism. In addition, the Body is depicted in the Return of the Stars as a figure of a mask and a costume. Furthermore, the Body in Lem’s novel is also interpreted as part of the Universe—as the boundary between what is temporary and what is infinite and transcendent.
