" '—All You Zombies—' "[a] is a science fiction short story by American writer Robert A. Heinlein. It was written in one day, July 11, 1958, and first published in the March 1959 issue of Fantasy and Science Fiction magazine after being rejected by Playboy.
"'—All You Zombies—'" further develops themes explored by the author in a previous work: "By His Bootstraps", published some 18 years earlier. Some of the same elements also appear later in The Cat Who Walks Through Walls (1985), including the Circle of Ouroboros and the Temporal Corps.
The unusual title of the story, which includes both the quotation marks and dashes shown above, is a quotation from a sentence near the end of the story; the quotation is taken from the middle of the sentence, hence the dashes indicating elided text before and after the title.
"'—All You Zombies—'" chronicles a young man (later revealed to be intersex) taken back in time and tricked into impregnating his younger, female self (before he underwent sexual reassignment surgery); he turns out to be the offspring of that union, with the paradoxical result that he is his own mother and father. As the story unfolds, all the major characters are revealed to be the same person, at different stages of their life.
The story involves an intricate series of time-travel journeys (see diagram). It begins with a young man speaking to the narrator, the Bartender, in 1970. The two of them relate in that both of them are from unmarried parents. The Bartender remarks that no one in his family ever gets married, including him. He wears an Ouroboros ring. The young man is called the Unmarried Mother, because he writes stories for confession magazines, many of them presumably from the point of view of an unmarried mother.
Cajoled by the Bartender, the Unmarried Mother explains why he understands the female viewpoint so well: he was born a girl, in 1945, and raised in an orphanage. While a fairly ugly teenager in 1963, she was seduced, impregnated, and abandoned by an older man. During the delivery of her child, doctors discovered she was intersex, with internalized male sex organs as well as female sex organs. Complications during delivery rendered the female organs unviable and forced them to give her a gender reassignment. The baby was kidnapped by a mysterious older gentleman, and not seen again. The Unmarried Mother then had to adjust to life as a man, despite an upbringing which left him unqualified for "men's" jobs; he had planned to get into space as a sex worker for male workers and colonists. Instead he used his secretarial skills to type manuscripts, and eventually began writing.
Professing sympathy, the Bartender offers to take him to the abandoning seducer, whom the Unmarried Mother wishes revenge on. The Bartender guides him into a back room, where he (Bartender) uses a time machine to take them to 1963, and sets the young man loose. The bartender goes forward eleven months, kidnaps a one-month-old baby and takes them to 1945, leaving them at an orphanage. He returns to 1963 and picks up the Unmarried Mother, who was instinctively attracted to his younger female self and has seduced and impregnated her. The Bartender nudges him to connect the dots, and realize that the seducer, the young woman, the baby, and the time traveler are all him.
The Bartender then drops the Unmarried Mother at an outpost of the Temporal Bureau, a time-traveling secret police force that manipulates events in history, to protect the human race. He has just created and recruited himself.
Finally the Bartender returns to 1970, arriving a short time after he left the bar. He allows a customer to play "I'm My Own Grandpa" on the jukebox, having yelled at the customer for playing the song before he left. Closing the bar, he time travels again to his home base. As he beds down for a much deserved rest, he contemplates the scar left over from the Caesarean section performed when he gave birth to his daughter, father, mother, and entire history. He thinks, "I know where I came from—but where did all you zombies come from?"
As the story is told as a disjointed point of view reference by several other points thereafter, this is the actual chronological history of "Jane" according to the story, although the story itself is still a classic example of a time paradox.
Philosopher David Lewis considered " '—All You Zombies—' " and "By His Bootstraps" to be examples of "perfectly consistent" time travel stories. Stating that it and other Heinlein time-travel stories "force the reader into contemplations of the nature of causality and the arrow of time", Carl Sagan listed "All You Zombies" as an example of how science fiction "can convey bits and pieces, hints and phrases, of knowledge unknown or inaccessible to the reader".
