I like to think. If I didn’t, this would be the wrong job for me. But I realize that as open-minded as I like to consider myself, I’ve taken a thick, black sharpie to certain areas of the philosophical map, scrawling “here there be monsters” and leaving them be. We’re all like this to some extent—it’s the flip side of interest—even if you’re super-curious, the things that interest you most become safe spaces. Comfort zones. And there’s nothing wrong with that.

But if you want to keep learning, it’s necessary to spend time in regions of reality that scare the crap out of you. The things you don’t want to look at. And if, like me, your unsafe spaces include the many catastrophes that could befall the human race—you couldn’t ask for a more affable, well-informed, tour guide than Josh Clark. Trained in history and anthropology, Josh is a writer and podcaster—host of Stuff You Should Know and now, The End of the World—a 10 part series that looks at the many ways humanity might go extinct. And what we can do about them. And why it’s all worth taking very, very seriously.
