Drawing from David Wittenberg's book, Time Travel: The Popular Philosophy of Narrative, as a guide, Evan Puschak goes in search of the origins of time travel in fiction. Along the way, he connects Charles Darwin's work on evolution to the largely forgotten genre of utopian romance novels to the depiction of time travel in modern sci-fi.
P.S. While I was in France, I met up with Evan for lunch (we happened to be in Paris at the same time). We'd never met before, and it was really strange hearing the voice of one of my favorite YouTube channels coming out of an actual person.
