How we engage with catastrophe has to show up in our social and cultural fears, anxieties, paranoias, and uncertainties. What scares us and how—and that things scare us—are a fundamental aspect of history. More on this in more detail, as I limp towards completion of my manuscript on toxic fear. But thinking more broadly about fears, and fears of the unknown, and unknown fears (fears we didn’t know we had?), these stories and imaginations probably shape a good deal of our histories. And we should acknowledge that. And, back to the catastrophic, it might help us to read more deeply into our cultural histories of fear—and how the catastrophic functions within the modern human condition. Below is another sound stub, linking three pieces of writing that resonated or helped draw on implicit connections that might not be there, but encouraged me to dig deeper into ideas about the uncertainties surrounding the abyss, the unknown, where catastrophe might lurk.
