[net.books] Time Paradoxes

I just finished a short (20 page) RAH story called "All You Zombies...."
This story deals with a time paradox, presented in Heinlein style.  I won't
comment on the physical probability of the story happening, but the paradox
is interesting.  The paradox is very similar to that presented in another 
one of his short stories called "By His Bootstraps."  Anyway, I thought the 
paradox presented in this story was unusual enough to summarize to this
newsgroup.  So...

   A time traveller, an older gentleman in his fifties, has set himself up 
as a barkeep in 1970 so as to meet a certain person.  A 25-year old man 
comes into the bar.  The time traveller engages in conversation with the 
man, who then tells his strange story.

   It seems the man was born a girl, and brought up in orphanage, never having
any clues as to parentage.  When the girl (man telling the story) is 
about 18, she meets a man.  They have a short fling and she winds up pregnant
and he winds up gone.  Nine months later she goes in to have the baby.  She 
wakes up in the hospital.  The doctor tells her a tale of how (s)he had two 
set of sex organs (each not fully developed).  The baby (a female) is fine, 
but having a baby did irrepairable harm to the female set of sex organs.  
All the doctors can do is perform subsequent operations and let her develop 
as a man.  Well, at least she figures she can raise the baby as the father.  
No orphanage for the little baby girl.  Three days later, the baby is 
snatched out of the hospital and is never seen again.  Now it is seven years 
later.  The man tells the time traveller that he would give about anything 
to get ahold of the man who ruined his life (got him (her?) pregnant).  

   The time traveller, of course, offers the man this opportunity.  They go
back to 1963.  The time traveller drops the man off to find the man that got
him (her?) pregnant these seven years past.  The time traveller says he will 
pick him up in a little while.  The time traveller jumps ahead 11 months to 
1964, locates the baby in the hospital and takes it.  The time traveller 
takes the baby back to 1945 and drops it off at an orphanage, making sure
that the baby gets taken in before leaving.  The time traveller then goes back
to 1963 to pick up the man, who is badly shaken.  It seems the man met himself
as a woman and seduced his younger self.  The time traveller then offers 
the man a job as a fellow time traveller, who accepts the job.

    It is now 30 years later, and the 25-year old man is now the time traveller
in the bar in 1970, waiting for his younger self to appear.

    Strange.  But, it is a rather interesting paradox (the baby grows up to
be the man who seduces himself as a woman who has a baby that is really 
himself, etc.)

Sound like he went and fucked himself.  (Sorry -  I couldn't resist :-)

"All You Zombies" is definitely a classic.

Try "The Man Who Folded Himself" by David Gerrold for an
interesting variation on the theme. I read this one about 
ten years ago. The writing style is good but not great. The plot
however, carries the Heinlein paradox to the extreme.

*** REPLACE THIS LINE WITH YOUR MESSAGE ***

Another great time-paradox short story is called Kingmaker.  It
appeared in an anthology of first-published short stories that won
some kind of recognition at least 7 years ago.  I don't remember
the name or editor of the anthology or the name of the author. 
General plot involves successive meetings of a famous political
figure and his biographer from 500 years in the future.

If anyone recognizes this short-story and can supply the name of the
anthology (and hopefully the year) or the author, please post it
in the net.

A good discussion of time travel is also in Larry Niven's collection
"All the Myriad Ways"  and is called "The Theory and Practice of Time 
Travel."
