“’All You Zombies—’” takes full advantage of the cause-and-effect paradox inherent in the concept of time travel. The tale assumes not only the existence of time travel but also its necessity. To forestall the atomic destruction of the earth, for example, agents of the Temporal Bureau must selectively manipulate what becomes the past, taking care not to leave too many anachronisms. Temporal agents do not change the past, for that is impossible; rather, it is their hidden presence in past events that ensures that history turns out as it really does. For example, the intervention of a temporal agent turned what could have been the nuclear disintegration of New York into what became known as the Fizzle War of 1963.

The Corps takes good care of its own, and many end up getting married to pilots.
Jane’s dream, though, is shattered in 1963. She is seduced by a...
