An extensive essay on science fiction and futurology is at the same time: an original and innovative attempt at creating a theory of the genre; a witty self-interpretation of Lem's works; an overview of world output of science fiction in search of authors and works that could enter the lists against scientific futurology and prove the value of literature in modeling the future of man.  Yet another „theory of everything” by Lem – of everything that deals with science fiction and its role in human comprehension of the world.
