By His Bootstraps

Robert A. Heinlein

4 ideas

  1. Bob Wilson becomes every visitor

    While finishing a thesis arguing that time travel is impossible, Bob Wilson is urged through a time gate by a stranger, while a second stranger tries to stop him and a fight breaks out. The gate drops him thousands of years in the future, where a ruler named Diktor sends him back through the gate. He comes to realize that the stranger, the objector and Diktor were all himself at later points, and the story leaves him as Diktor, about to set the same sequence in motion for his younger self.

  2. The notebook with no origin

    Bob uses a worn notebook that translates the future people's language. When it falls apart, he copies it into a fresh one, which later becomes the worn original he first received. The information in it was never written by anyone and exists only because it loops through time. This is the bootstrap paradox: an object or piece of knowledge that causes itself, with no first author.

  3. Choosing freely inside a fixed loop

    When Bob relives scenes he has already watched, he deliberately tries to say and do something different. Each time, his own reasons lead him to reproduce the exact words and actions he saw before. The story argues that a fixed history does not feel like compulsion from the inside. The loop is closed because of the agent's choices, not in spite of them.

  4. Role determines how events are read

    The same argument in Bob's room looks like a sinister manipulation to the youngest Bob, a desperate recruitment to Joe, and a futile intervention to the oldest version. The facts are the same each time; only his position in the sequence and what he knows change. Reading any conflict through this lens means asking which participant's slice of information produced a given interpretation, including a person's reading of their own past self.
