All three caravans of the Traveling Symphony are labeled as such, THE TRAVELING SYMPHONY lettered in white on both sides, but the lead caravan carries an additional line of text: Because survival is insufficient.
“Survival is insufficient” is a line that I heard twenty years ago in an episode of Star Trek, and it stayed with me forever. It just struck me as an elegant expression of something that I believe to be true. You don’t have to look to a fictional future to find that phenomenon—as a species, we do things like put on plays in war zones and play musical instruments in refugee camps. You could look at such activities as a waste of time and resources in desperate times, or you could look at it as the thing we do that reminds us that we’re human.
