Overheard on my volunteer shift in the bookstore the other day: one member of a couple declaring very seriously to the other, as the duo browsed the $5 bestseller table, “I’m just opposed to time travel in general, you know?” I was unable to crane my head around the computer without it becoming obvious I was eavesdropping, so I didn’t hear the rest of the conversation– but it did go on, giving the impression that there was much of urgency to discuss, in the way of real-world possibilities (and their attendant merits, ethical dilemmas, and so forth) of leapfrogging from one era to another.
Sure, this topic has provided grist for literature and film both great and inane; I’ll admit to finding the first Bill and Ted movie, well, excellent, maybe because it could really qualify for membership in both of those categories at the same time. And why not discuss time travel seriously; not too long ago, space tourism was inconceivable, and now we’ve got bazillionaires chomping at the bit to spend a few hours in oxygen- and gravity-free zones, rather than throw down some of that cash on, say, the alleviation of global poverty or at least something that won’t pollute the atmosphere with a sloshing tank of rocket fuel and other detritus.
But I digress. Maybe confronting supposedly impossible scenarios, such as time travel, could act as a training ground for development in mature civil discourse. After all, getting shouted down and insulted by your opponent regarding the ethics of popping into your parents’ teenage years is far less likely than being (emotionally, at least) mauled by an ideologue at a town hall meeting. I’m certainly not going to base a curriculum in civics on the possibility, but maybe because there’s less at stake in digging into far-fetched hypotheticals, people are more willing to entertain each other’s conflicting views and arguments– and if they realize they can get along even in a heated debate about worm holes or the risk of retro- (or would it be pro-, here?) actively annulling your own existence, they could take it to a real-world level and be willing to work together to confront anything from potholes to prison reform.
That rosy little pipe dream is probably akin to the faith I want to have in kids– and adults– who really took Harry Potter, especially volume 5, to heart. If those readers can remember that particular volume’s beautiful elucidation of how ideology works– and the entire series’ wrangling with the noblest way to confront very difficult, very terrifying situations, and apply it to their own world, I’m willing to refrain from throwing in the towel just yet. And if an examination of magical worlds can do that for us, well, so, too, can a variety of other apparently frivolous conversations. Carry on, then, with your bookstore conversation, sci-fi couple. Carry on.
