"I know where I came from, but where did all you zombies come from?""—All You Zombies—" (1959) is a short story by Robert A. Heinlein that presents to the reader an interesting time paradox. "The Unwed Mother", as a bar patron calls himself, unloads his life story onto a willing barman. The barman, however, knows more about The Unwed Mother than he could ever guess.At roughly a dozen pages, "—All You Zombies—" provides a provocative story and incorporates many of Heinlein's favorite themes.A film adaptation called Predestination, starring Ethan Hawke and Sarah Snook, was released in 2014.As the story contains a twist ending, it is recommended you read it for yourself before reading the associated tropes.
This short story provides examples of:
- Everyone Calls Him "Barkeep": The narrator is only referred to as "the barman" until the end of the story when he reveals his real name: Jane.
- Foreshadowing: The barman becomes very annoyed at the song "My Own Grandpa."
- Fun with Acronyms: The same "elite military service corps" is referred to at various points in history as the Women's Emergency National Corps, Hospitality & Entertainment Section, the "Space Angels" or Auxiliary Nursing Group, Extraterrestrial Legions, and the Women's Hospitality Order Refortifying & Encouraging Spacemen.
- No doubt inspired by the Real Life Women Airforce Service Pilots and their naval counterparts, Women Accepted for Voluntary Emergency Service.
- Help Yourself in the Future
- Luke, You Are My Father / Luke, I Am Your Father: And mother.
- Most Writers Are Writers: The Unmarried Mother writes short stories for magazines.
- My Future Self and Me
- My Own Grandpa: In possibly the most convoluted, mind screwing way possible.
- Noodle Incident: The Mistake of '72.
- One Degree of Separation: The various characters are connected by zero degrees of separation.
- Ouroboros: The bartender, quite understandably, wears an Ouroboros ring.
- Parental Incest: Again, all part of the story's Timey-Wimey Ball.
- Screw Yourself: After the protagonist has his one night stand with his female past self, the barman comments that the idea of seducing yourself is irresistible.
- Stable Time Loop: The barman already knows the recruitment will work. After all, he remembers the other side of it.
- Tangled Family Tree: It's a very tangled family tree, considering that there's only one person in it.
- Take That: Jack Chalker claimed he wrote Downtiming the Nightside to address the questions this story raised but failed to answer.
- Time Paradox
- Time Travel
- Time Travel Tense Trouble: "The By-Laws Of Time" read as such:Never Do Yesterday What Should Be Done Tomorrow.
If at Last You Do Succeed, Never Try Again.
A Stitch in Time Saves Nine Billion.
A Paradox May be Paradoctored.
It is Earlier When You Think.
Ancestors Are Just People.
Even Jove Nods.
- Timey-Wimey Ball: Don't think too hard on the paradox of the story. You will start bleeding from the nose.
- Title Drop: In the closing lines.
- Twenty Minutes into the Future: As with all Heinlein's works. The latest date given in the story is 1993.
- Wrong Genetic Sex: The protagonist starts out as an intersex female and...it gets complicated. Her actual degree of intersexualization approaches true hermaphrodism and isn't biologically possible, at least for normal humans. But of course the protagonist isn't related to any other humans.
- You Already Changed the Past: The barman remembers all the parts of the story from when they happened to him in his original timeline. He's just acting out his part now to complete the loop.
