Ijon Tichy is an ordinary space traveler whose extraordinary curiosity leads him to the very fringes of science. Their plans are grandiose, the bargains they make too often Faustian, for the ends these scientists pursue concern humanity's greatest and most ancient immortality, artificial intelligence, and top-of-the-line consumer items. By turns philosophical, satirical, and absurd, Lem's stories follow Ijon's adventures as both an observer of—and participant in—strange experiments. Faulty time machines, intelligent washing machines, suicidal potatoes—Ijon Tichy navigates them all with common sense and in so doing shows why he endures as one of Lem's most popular characters.
