Copied from Poul Anderson Appreciation:
I am continuing to read and discuss John C. Wright's article on time travel. See here.
My second post on this topic refers to Alfred Bester, Charles Dickens
and Superman but not to Poul Anderson so that post will remain on the
Logic of Time Travel blog whereas its predecessor will probably be
copied here since the page view count continues to indicate that more
people read this blog than that one. I value discussions of time, logic,
free will, Heinlein's "By His Bootstraps" and Anderson's There Will Be Time and want to share them as widely as possible.
In Audrey Niffenegger's The Time Traveler's Wife,
Henry sees his future wife draw a picture and tells her not to sign it
because he has seen it unsigned in the future. See signs it. When he
returns to the future, he looks for the picture on the wall and it is
not there. It has fallen behind the fridge. When he retrieves it, it is
unsigned. She had trimmed the signature off because she did not want to
risk Henry returning to a future other than the one he remembered. In
this novel, there seems to be only a single consistent timeline but the
characters want to make sure of that.
My comment would
be: in a single consistent timeline, logic dictates that, if the artist
were the sort of person who would not have trimmed off the signature,
then Henry would have seen her draw the picture and would not have told
her not to sign it because he would remember having seen it signed in
the future. This has taken us away from Poul Anderson but it remains
relevant to the kind of time travel in his There Will Be Time.
