In the paper the author interprets a number of Stanisław Lem’s works, trying to liberate himself from humanistic trails and head towards posthumanistic reading. The problem of rationality present in many Lem’s texts is a good demonstration of this possibility. In Golem XIV, Observation on the Spot, Solaris, Lem argues, in various manners, with the anthropocentric vision of the mind, arguing that it is too narrow, limiting and intellectually confusing. This makes man face a challenge of giving up man’s universalistic claims, but also of reflecting on man’s place in reality.
