So, What Time Is It?
It’s not often that we in the Fantasy and SF community get two time-travel related productions – the movie Arrival, and the TV series Timeless – at once. Even better, we’re being served two different theories of time, and time travel. (There might be some spoilers for those of you who haven’t seen either film or TV show, so watch out.)
I’ve talked about time as a literary device before, and I’ve looked at time travel specifically as well. In the earlier piece I mentioned the 17th-century English philosopher John Locke, and his Essay Concerning Human Understanding (1690), in which he suggests that humans don’t experience time (or any other abstraction) directly. What we experience is actually a sequence of events, which he calls “duration.” One thing follows another, in one direction, which give us the idea that time is linear.
Aside, Fun Experiment: ask someone to point at yesterday. As a general rule, they’ll do one of two things. They’ll point behind them, or they’ll point to the left (or maybe to the right, if their culture reads that way)
