The following discussion of time travel precedes the use of the device:
Dow smiled.
“The eternal question,” he said. “The inevitably objection to the very idea of time travel. Well, you never did, did you? You know it never happened! I think there must be some inflexible law which forbids the same arrangement of matter, the pattern which is one’s self, from occupying the same space time more than once. As if any given section of space time were a design in which any arrangement of atoms is possible, except that no pattern may appear exactly twice.
“You see, we know of time only enough to be sure that it’s far beyond any human understanding. Though I think the past and the future may be visited, which on the face of it seems to predicate an absolutely preordained future, a fixed and unchangeable past — yet I do not believe that time is arbitrary. There must be many possible futures. The one we enter upon is not the only way. Have you ever heard that theory explained? It’s not a new one — the idea that at every point of our progress we confront crossroads, with a free choice as to which we take. And a different future lies down each.
"I can transport you into the past, and you can create events there which never took place in the past we know — but the events are not new. They were ordained from the beginning, if you took that particular path. You are simply embarking upon a different path into a different future, a fixed and preordained future, yet one which will be strange to you because it lies outside your own layer of experience. So you have infinite freedom in ail your actions, yet everything you can possibly do is already fixed in time.”
“Why, then — then there’s no limit to the excitement a man could find in navigating time,” said Eric almost reverently...
